How would this card get to 90c before crashing in games anyway? I am 1000 and I am not even breaking 75c in fur mark. I guess I need that overvolted bios.

Furmark isn't a very good test anymore due to current limiting and drivers throttling the card when simply detecting that furmark is running. I go by what my temps are with vsync off in games.

So did you make the coolers yet? I'm wondering how things turned out.

I'm thinking that win8 just lacks a driver database for it. Installing a driver manually should make it work.

Personally I recommend that you do not get an AMD APU. I tried to get an A10-4600m with a 7660g running well and I simply could not do it. The system had very bad stuttering that I simply could not fix. I doubt that the stutter was not just my system in particular since with the tweaks I did (locked NB frequency to max, locked CPU to 2.7GHz/3.2GHz, tightened memory timings including CAS)I was significantly outscoring a default APU, but the stuttering was still just as bad.

I think the main reason for the stutter was terrible driver management. With GPU-Z and afterburner you can see the GPU clocks switching several times per second between 324, 485, and 685. I tried to lock the GPU frequency to max, but disabling power saving features would lock the GPU to either 324 or power-on clocks (200).

The stuttering was so bad that I would definitely recommend an HD4000 over it even though in benchmarks the APU usually scores much higher. If you can get a dedicated GPU though in your price range then by all means get that over the HD4000 though.

Thanks for the very informative post. I'd forgotten that mPCIe only goes as high as PCIe 2.0 x1. Being pretty recessed it was kind of hard to make out what kind of slot it was but it sure looked like mPCIe on the surface. But what do I know; I never would've seen the difference in pins.

Yes the Ultrabay is PCIe 2.0 x8. So you're saying that the Lenovo actually implemented a proprietary slot which is essentially a full-sized PCIe x16 with lines removed to make it x8?

Yeah it looks like it's just a proprietary x8 connector.

On a side note the mPCI-E connector was originally designed for x2 and it has enough pins for it, but x2 mPCI-E never materialized. The only devices that need more bandwidth than 1GB/s (PCI-E 2.0 x1) are graphics cards.

Couple reasons, the system was crashing with a slight overclock + overvolt. Neither card exhibits this behavior when run by themselves so its not a GPU issue. The PSU never shut down but I was getting warnings from the Asus monitoring software (not the most accurate in the world) that the 12v line was dropping to 10.

12V rail is very easy to measure with a multimeter. Just stick the leads in a molex connector.

That connector has many more pins than a mPCI-E connector. It just happens to have the break in a similar spot to make it look like one.

It would be suicidal to rely on only an x1 link for SLI like that since the ultrabay GPU would need to send its framebuffer and other synchronization data over PCI-E to the internal card. Adding PCI-E links only requires 4 signals each. The reason PCI-E x16 has so many lines is mainly for power and the motherboard not knowing the capabilities of the card that is being plugged in (an x4 card must work in an x16 slot), but when you know what exactly is going to be plugged in, you can cut out a lot of lines.

I am guessing that the ultrabay GPU is x8 PCI-E 2.0. Possibly x4 3.0, but I doubt lenovo made a good enough connector for 3.0. You can check if it is or not in GPU-z. Just make sure you do the little render test to make sure the link is fully engaged.

As for hooking up an eGPU to the slot, you can't without an enormous amount of work and resources. SLI requires 1 card to be a master, and others to be slaves. The BIOS will likely be set up to always treat this slot as a slave. And that is the least of your problems. The main problem would be to somehow design and manufacture your own custom PCB to plug into that slot and wired to a full size PCI-E slot. It takes very good connections to transmit PCI-E 2.0, let alone 3.0.

You're basically making your own PE4H but without the cables and without any documentation on the pinout of the motherboard connector.

Well from the article it would appear that everything should be just fine which rests my mind a little. First off I just want to make it abundantly clear that I'm a bit of a noob when it comes to PC building. I've been a console gamer for years and then a laptop owner for 3 years so my experience with these details is only recent.

With that said. The guy at the computer store that sold me my 2nd Titan told me that I'll be under-powered with this PSU and that the wattage only tells part of the story. He pulled up the details for the Titan and showed me this: 600 Watt Power Supply (minimum 42 Amps @ 12 volts) and he went on that my PSU can not accommodate 42 Amps x 2..

Do you understand any of what he meant?

Plus, does anyone truly know if this Legacy mode for PCIe really affect my GPUs performances??

That salesman is a dick. The AX860i is a very high quality PSU. That 600W figures is assuming you're running a titan full load and have like 6 HDDs, 6 fans, several CD-ROM drives, a floppy, a ZIP drive, a high power CPU, and you lined your case with christmas lights. Titan has a TDP of 235W. That means 470W for 2 titans alone, then add 250W for a realistic conservative number for the rest of the PC. 720W, not this 1200W BS.

You might have problems if you do a lot of overvolting then run furmark with current limiting disabled, but that's it.

@Brian What makes you thin the 12V rail was an issue? Was the PSU shutting down? When messing around with my 580 in furmark I could drop a 550W PSU down to 11.48V. I thought it may have been hurting my overclock so I got an HX850 which never dropped below 12V, but it made no difference.

What are the major differences in the 1.0v all the way to the 1.5v?

With only having the 240w PSU am I limited to what volts I can run?

With my CPU over 4GHz and using the 1V BIOS I need to turn down by screen brightness to prevent my 240W PSU from shutting down. My GPU temps are mid 70s with fans on automatic so I will go higher voltage after getting a stronger PSU (and VRM/MOSFET) cooling). You should be able to push higher voltages than me though since I doubt your CPU will pull over 80W in games like mine.

Hello to everyone

I'm new to laptops...since i can remember I always used desktops...but now,for working reasons,I am forced to switch to a laptop. so I bought the laptop ,I tought was the best,the p370em3 .

but for me,used to play with Evga and Asus mb's bioses ,it was kind of a shock to see that a 4000 euro laptop has the same bios options as a sh...ty 300 euro one.I mean ,this it's supposed to be the enthusiast niche.

Ok,I have a 3920xm CPU and i try to run with a Corsair Ram kit CMSX8GX3M2A1866C10 ...but it does not works,the W8 keeps crashing after a few seconds,and MemTest is failing.The modules are installed under the keyboard,if that matters.if i couple the ram kit with a second 1600 kit in order to slow them down to 1600 it's ok.I've tried all bioses...currently I have Prema's 1.0.4 2T ,still no go.

So ,is there any way to pass this 1600 barrier?

is there a 1866 Ram kit known to work well with this machine,possibly in 4 x 4 configuration? Or better yet a 2133 one?

oh.one more thing.I bought this laptop with only one 680m .don't have the cash,I will add a second one later: but nearly all clevo ressellers refused to sell me the 3d version with only one card,they said is not recommended by Clevo,said the gaming is impossible.

in the end I've managed to convince a German retailer to sell me one ,and frankly,until now ,i only had issues with one game:Batman Arkham City.It crashes as soon I hit start button.all other games,Crysis 3 ,Mass Effect 3 ,CoD BOps2,Max Payne 3,Hitman Absolution are running flawlessly 2d and 3d ,with the GeForce Experience optimal settings.

So,does anyone know why Clevo won't sell non-SLI p370em3's?

could this be the cause of my ram problem?(highly unlikely,but I'm new on laptops)

will be thankful for every imput.

Thanks

Yes clevo BIOS options are horrendous. Luckily though you can do most things with XTU that you would normally do with proper BIOS settings.

You're only running 2 RAM sticks? On the P150EM and P170EM if you only have 2 sticks you're supposed to use the memory slots under the backplate, not the keyboard. I'm not sure if it really matters though and if the P370EM is the same.

Hello, I don't know where to ask so I thought I'd ask it here.

So, I've flashed my GTX680m with proper vbios. Everything is fine except the one thing. Clocks are jumping randomly between 771mhz to 980mhz after OC (980mhz is my target). Anyone know the cause of it?

Notebook is MSI GT60-0NE.

Best regards.

PS. sorry for my english.

If the GPU is under light load it will automatically clock down to save power even when plugged in. You can prevent this with nvidia inspector if you want, but I haven't noticed the clock changes causing any stuttering so I don't think this is something to worry about.

The card will slow down to 758 if it reaches 90C, but yours is dropping to 771 so it looks like it's just not being stressed.

Unlocking it slowly Loving this beast and among gaming and stuff i have been playing around with settings now. I need to get some faster memory for this thing as its got junk in it atm, then will test some more and see what happens!

NVIDIA GeForce GTX 680M video card benchmark result - Intel Core i7-3930K Processor,Notebook P570WM score: P14504 3DMarks

How did you overclock the CPU? You got a real BIOS?

Sorry for noobish question, what is the difference between the stock heat-pipes and the triple 3 pipe CPU cooler?

I've been trying to figure this out too since in theory 2 8mm heatpipes can transfer heat more efficiently than 3 6mm heatpipes (2*4^2 = 32 vs 3*3^2 = 27).

I think the reason the 3 pipe is better is because it has more contact area. Many laptop heatsinks have the heat pipes embedded within the radiator for heat to transfer from the heat pipes to the radiator better. I think since the m18x does not do that and instead has the pipes on top of the radiator causes surface area to be a bottleneck.

Yeah i will do some soon. Its a great design like the X7200 was but just uses a bigger sink.

Yeh im using that OV 1.025 bios atm as the next one up doesn't really help much really so id rather be on the lowest i can. Those runs were @ 1049/2200 i think. Yeah your right about the PCi 1.1 but there is only a slight drop in score due to it so its no big deal unless you wanna break records or just have a huge numbers which im not worried about. I get higher FPS from this machine than i did with both the P370EM and the M18x and i can game at 980mhz and it runs sooo cool so im happy as.

As far as the bios yes it sucks bigtime! I don't even know how you are overclocking at all ??? XTU comes up and allows you to set the settings but then when you reboot, it says error cannot apply those changes etc.. Was giving me the shits so i uninstalled it. lol Its only a matter time before there will be a nice bios for these machines as there are a few people on "notebook review" forum that have them and i think Xotic pc has some tweaks already. Mine runs really cool so i have a fair bit of room to OC having the fans 100% of coarse.. Most good 3930k,s chips can go to 4.5-4.6ghz with stock volts which doesn't make that much more heat. I have 2 that can do it and 1 needs a lot of volts so depends on the chip is how its gonna be and if your lucky!

To overclock my P150EM I need to edit the BIOS with AMIBCP to force higher turbo ratio limits. Each multiplier change = BIOS flash. It's annoying, but it works. PM me if you are interested.

lawtq did you find another method or are you doing the same thing I'm doing?

FPS drop may be due to instabilities in the system. In your case it may be because of the CPU throttling.

If you set the clock to something lower, then you probably will get a more constant performance.

You have mod your cooling system?

It has to do with the VRM and MOSFETs overheating. I replaced the MOSFET cooling pad with a copper shim and it lets me sustain another 10 watts or so. The system will toggle turbo on and off if I run over 75W for too long. Before the shim turbo would disable in the low 60W range. This will occur with the CPU temp in the upper 80s. The shim made a direct impact with no improvement in CPU temps so it is definitely voltage regulation related.

Yes but I can see why clevo did it, they're not confident enough with the cooling for the CPU. Tbh it can't handle an oc'd 3930k. The thing is I could oc and undervolt at the same time. But that control is taken away, the x7200 was great as I could oc my 980x to 4ghz on all cores while undervolting slightly which kept temp good

Clevo does provide VRM schematics if you want to try to figure out a hardmod to reduce voltage. There did not seem a to a practical one for my P150EM but perhaps that is not the case for you.

Also BCLK overclocking does not automatically raise the VID like raising the multiplier does. I'm not sure if FTIC will work for your chipset but if it does then you can follow http://forum.techinferno.com/general-notebook-discussions/2091-lets-enable-overclocking-all-6-7-series-laptops.html to get BCLK overclocking. I only got 104.17 fully stable so it doesn't get you very far, but that's around .05V off VID at the same clocks as just raising the multiplier.

I really really thought hard about it, but decided against for the fact I'm always tinkering and removing heat sink which would mean a new application would be needed each time. Too expensive!

Other pastes were just not up to the task so I'm using coollaboratory liquid ultra. Just as good and removing heat sinks doesn't require new application,just a tidy up of the liquid metal with the brush,evening it out.

Around 4c better than normal paste for me on my CPU 3930k and sli 680m.

OK I'll look into that. I thought about that stuff but I never saw someone try it on a raw processor die, but you did with the 680ms so it looks like it's OK.

I also thought of indigo since it would discourage me from taking the heatsink off and wasting time messing with the laptop, but not sending $9.50 down the drain each HS removal is nice.

Update:

Just ordered liquid ultra. It looks like people who didn't have good results with it either got a bad tube or applied it wrong (used the q-tip).

Actually my laptop had a 120W PSU. I mod a old 180W HP PSU in order to upgrade my GPU (560M to 680M).

I'll buy a dell 240W or 330W PSU for it. I'm designing a big mod for the cooling sistem. I don't think

it will be a issue. I'm from Brazil and I was just thinking if it will worth the $400.

I'm playing Crysis 3 and I saw 100% CPU usage many times.

You can give a idea of how much improvement I will get with this upgrade?

Worth a memory upgrade from 1333mhz to 1866mhz?

The memory speed increase will help. Your current memory can likely run much faster though if you force it with XTU or flash it with thaiphoon burner.

As for CPU I will occasionally get VRM temperature throttling in BF3. When it cuts from 4.3GHz to 2.4GHz my fps will sometimes drop from the low 60s to the high 30s, so CPU speed matters.

Yeah my p570wm is great too. Came from the x7200 which I liked too but its 480m gpu was pants!

My oc'd 680m's are at 954/2349 and average 65c in games and I have demciflex custom made on all the 4 fan ports under the laptop protecting from dust! Games are making my 3930k Max out at about 58c after exteded play. 3dmark will get CPU to 62 and gpu to 69c though, still good. This is all using auto fans and the fan profile on the p570wm ain't great tbh. Cooling can be even better cause fans come in too late, most of the time the 2nd CPU fan doesn't even operate! Gpu fan profiles are good though

Only thing pissing me off is the CPU oc abilty which clevo has made sure is not there for this system. Its messed up! Example is if u do a small 3.7ghz oc on CPU vcore is rammed up to around 1.35v! Which is enough for a 4.3ghz oc! This produces way too much heat for daily use! There is no way of controlling CPU vcore! Gpu could perform better also as clevo have locked the pcie at 1.1 instead of 2. With the nvidia patch we could unlock pcie 3 but nope, clevo says 1.1 only! Grrrr!

Apart from that its an excellent machine. If BIOS is sorted out to allow cpu oc while controlling vcore I'll have an orgasm!

And I forgot to mention I use coollaboratory liquid metal-ultra paste on CPU and gpu's. ..very, very carefully lol! Around 4c better than any other paste for me

I hear ya about the Vcore for mild overclocks. Same problem with a p150EM. Only solution I see is to make 4.3GHz thermally stable, which is no small task. Fixing this would require having real BIOS settings, which it seems clevo is committed to never doing.

Hey thanks! Yeah i am pretty happy with it and so one must be for how much it costs! lol Its just a monster with a Ton of potential, im glad i got it. Will post up more as i test and play around with it further.

111

*Damn, this thing runs sooo Cool. Great cooling design on this monster for sure!! Playing games now at Ambient room temp of 23 degrees C now running the 1050v OV bios the 680M,s don't go above 74 degrees. And CPU doesn't even go above 60 degrees C. WOW! Gaming @ 980mhz / 2100mhz and killing every game.

Are those temps with the fans forced high?

Great CPU temps but it makes sense if you think about it. Games have a hard time using 4 cores let alone 6, so it's like you're running a regular mobile quad core but the cooling is overkill. What does prime95 and the like look like?

Looking at P570 cooling gave me an idea for something that I think will work on a P150. Move the fans back and put in an extra radiator. Buy extra GPU cooler and add the core radiator to the CPU side and memory/VRM radiator to GPU side. That HAS to make a difference assuming I don't mess up.

Yeah pretty damn good. Did a base Stock default run of 3dmark11 and CPU never even went over 60 degrees (100% fan speed on) And GPU,s 60-65 degrees C and 29.1 degrees C room ambient temp. Mind you its stock and 3dmark11 states it was only 3.2ghz. Big jump in physics score as i expected due to ram running in Quad channel. There is a huge difference running in Dual and quad channel as i just tested it. CPU score was 10,780 dead stock untouched at only 3.2ghz and ram @ 1600mhz CL11 and to get the same score on a mobile CPU 3940XM it had to be at around 4.4ghz so i think im liking this according to what it is doing dead stock. Seems to have a lot more potential but will see soon enough after more playing around!!

Here are the temps after that benchmark: remember the room temp is 29.1 degrees C lol Max temps are what it reached in 3dmark11 with fans 100%. The idle temp you see there are with Fans back on Auto. On average with this Ambient it idles at mid to high 40,s.

Those are great temps for that room temperature. I'm just worried that XTU won't work so you'll need to use AMIBCP to overclock, which is a PITA.

So how are temps? Can you overclock it with XTU?

I'm tired of thermal pastes drying out on me. I'll get good performance at first, but then the paste starts drying out and temps start going up 3-5C. shin-itsu would start drying out after a month, and PK-1 after 3 days (although the PK-1 beat the shin-itsu substantially before drying out and tied it while dried out). AS5 dried out too bad when I tried it years ago so I'm under the impression that pretty much any paste will dry out, so I figure I'll try something that's not a paste. There's also the plus of it outperforming everything else. I am just 2-3C away from being able to run BF3 with the CPU fan on medium at a constant 4.3GHz and I think that if I get indigo to work then I'll get that 3C if not more.

So indigo xtreme is designed for each individual socket for desktop systems. Installation is to place the thing on the IHS, then seal it on the motherboard. Clevos have a fairly high surface area heatsink, so I think it may be possible to apply and seal on the heatsink. I don't see why applying it to a heatsink instead of an IHS would make a difference.

So does anyone here have experience with indigo xtreme? Do you think there's a chance of being able to apply it properly to a laptop?

Yes your current CPU will be holding you back in some games like BF3. You'd need to be able to overclock the 2920xm for it to be a significant improvement. I don't know if XTU will let you overclock or not even if you flash on a 170HM BIOS, so it may be necessary to set overclocks by flashing the BIOS for each multiplier change (which I have done with my P150EM).

Another problem is the 150HM cooling unmodified won't be able to handle a 2920xm at any higher than stock. You will get headroom though if you lap the CPU heatsink to get rid of the bends clevo put into it during manufacturing, but it won't be much room since the 150HM has an aluminum CPU radiator (I paid extra for copper).

And the final problem will be power. I'm surprised that you're not getting PSU shutdowns already with your 180W PSU. I have a 240W and it shuts down on me with the 680m under load and the CPU pulling 75+ watts. If I use the 180W the PSU will cut out with any overclocking at all.

So it's up to you. You can get significant gains with an xm CPU, but it will be a lot more complicated than just getting a new CPU.

What PCI-E are you running with these cards? I assume both cards are at least x8?
