Hey guys,

The slave GPU fan inside my P375 is giving me some trouble. A few members report odd fan noises but obviously all cases are exclusive of each other.

I popped open the case and disassembled the fan to diagnose the issue. It seems that whenever the fan makes contact with pressure to another object, the fan make a strange buzzing noise.

Hence, when the fan is screwed in properly, the noise occurs. If the fan is removed from its housing and spun freely, the noise does not occur.

You'd like this would be caused by vibration but it seems this isn't the issue and is too ambiguous to try and resolve via the forums.

I've tried searching for the fan part with no luck. Does anyone know a site I should be looking at? Should I call up Sager or Clevo directly?

The laptop was ordered from Xotic PC (from the original owner) just over a year ago, so the manufacturer's warranty is out of date.

Thanks a lot for the help.

Anyone have an update on this? I have a P375SM that I just bought a 120hz screen for (from the P370SM3).

I finally found the part # I need (which led me to this thread), but we will see where this goes!

Thanks.

when i run the backup.bat file no backup is being created. what am i missing?

These 375sm GPU heatsinks will fit a 370em correct? I'd like to slap these onto my 680's

Yeah unfortunately the slave card on the P370EM is always going to be an issue due to the design they went with. The slave card heatpipes for the sink are just too long and have to travel too far to be efficient. The main GPU is better but still not optimum. best you can do is re paste and make sure for a good contact, there are a few mods and tricks on here you can do. And if you want to go further lapping the sink surface also helps but the problem will always be there, just with less effect.

Here is an e.g where you see the 2nd GPU and how far the pipes have to travel..

This is great info. Thank you! Kind of a bummer with the design. Maybe I can go with some 375EM heat-sinks. That could always help. I could always repaste, too!

It looks like this may be a bug with precision. The graphic reports 91C while the graph says 45C. The P370EM is known for high temps anyway though.

As for cooling improvements, you could get 375sm heatsinks, which have bigger heatpipes and radiators for the GPUs, or you could work on die contact with your current heatsinks.

GPU-Z is actually showing you GPU1's temp (Primary),vs. GPU 2 (slave). I verified that there is no bug with Precision. They match up when I have them aligned on the same card.

It just looks like Crysis at Ultra settings is very intense and the cooling on the Sagers, like people have mentioned, isn't very good

I logged 3DMark11 on stock temps and voltage and it maxes out at 84c.

Thanks for the replies, man.

I'd love additional members to chime in if they have any insight!

Then, here's the temps while benching at +220/600 on stock voltage.

Clearly a temperature and throttling issue.

Kind of stuck on what to do. Looks like there isn't much room to OC on this P370 due to heat! I wonder If I can apply a better heatsink and/or thermal paste to the cards?

Even Crysis 3 throttles due to heat with STOCK clocks.

Check it out.

GPU-Z must be monitoring the Primary card. It's at ~50c.

But my slave is at 91c! Stock voltage and clocks...

This is playing Crysis 3.

BF3 is just fine sitting under 80c.

Weird!

How hot is the slave card? Usually that runs hotter than the primary on the P370.

Well, my labeling might be wrong.

The identities of the cards are 0 and 1.

If you take this into account, I assume 0 is the primary and 1 would be the slave. #1 is running hotter.

The slave would be the one I am experiencing the issue with, then, and it's running at a little over 90c on stock clocks/voltage in Crysis 3.

I'm going to go home and make sure everything's gravy when running BF3. If not, then it's possible the connections between the heat-sink and card might be an issue.

Anyone? I will Paypal and buy you a beer

Hey all,

Just started posting on the forum. Lots of useful information here! Thanks for the responses thus far.

OK, so here's what's going on.

Flashed both cards with slv7's Clevo 33.10 non-OV bios.

Using Precision X to monitor and OC.

Everything was going well. +220 on core, +600 on memory.

Temps playing BF3 around 80c.

I could bench 3dMark11 showing no signs of throttling. 12.5k score. Vantage score of 35k.

This is with my 3740qm at 41x 40x 39x 39x and my memory at 9-9-9-24.

So, I decide I want to OV a bit.

I go with the 1.050 version of 33.10 and I notice that my bench numbers dropped. Now, this is probably a fault on my end, as I wasn't logging temps with Precision X during this test.

However, I switched to Nvidia Inspector, and my recorded max-temp, albeit I need to make sure that this was my primary GPU, was 78c.

Note that my bench numbers dropped with the SAME clocks, which leads me to believe that the card is throttling due to temperature. I dropped to an 11.9k on 3DMark11 during this period.

I try some other versions of the VBIOS. The 1.000 and the 1.025. No dice. Around the same scores.

I notice that the performance IN-GAME is not affected. Everything runs great with OV and higher clocks. I was able to run 1050/2400mhz in game with no issues and increased performance. Temps no higher than 80-82c in Precision X (primary card). So, even though I can't bench well, I decide let's go for it since my in-game experience is improved and I show no signs of detriment to the system.

Today, I try to give Crysis 3 a try.

Oh, no.

On max settings, I'm recording temps of 90-94c. And it's perfectly clear that the card throttles itself when it reaches 90-92c.

Runs like butter during less intense areas, but as soon as the card has to bump in performance, temps spike and card throttles.

I immediately know that this is exactly what's happening during benching, and Crysis 3 is a very intense game.

I decide to mess around with the VBIOS again to decrease temps.

I move down from the 1.050 to the 1.025 to the 1.000. No dice. Temps still hit 90c with my +220/600 settings.

THEN, I start detuning to see if I can decrease temps. Again, no dice. How?

I end up going BACK to the non-OV bios and this is what concerns me.

Crysis 3 at stock clocks is still hitting 90c on my computer...

Now, I don't think I've done any damage to the heatsinks. My card would be at much higher temps at idle if that were the case.

What concerns me is that this game is so intense it's causing my primary card to overheat and throttle.

I'd love for an experienced vet to help me out here.

Now, if running Crysis 3 at stock clocks (on very high) can cause temps to hit this, so be it, but I can't seem to think this is the case.

Hope this all made sense.

Any help would be appreciated.

I am not. Think this is the issue?

I will download it now.

Are you running throttlestop to prevent the CPU from losing turbo when the GPUs are active? P150EM and P170EM will do that when the GPU draws a significant amount of power.

No dice Same results.

Have done a bit of testing over here

Setup is:

Clevo P370EM

i7-3740QM (41x40x39x39)

Clevo 680m SLI

16GB DDR3-1600 at 9-9-9-24

128GB SSD

------

Flashed using the 33.10 VBIOS. Scored 12.5k 3DMark11 and 35k on Vantage.

Tried running the OV version of 33.10 and my scores ended up dropping (even at same frequencies).

Stable on the non-OV version was 980/2400.

Again, the same frequencies on the OV version actually dropped my scores. While I did not have any issues in game, I had issues when benching.

Finally, I tried using the MSI version of the OV bios on my Clevo cards. They work fine However, no score improvement.

My GPU temp isn't exceeding 80c. I tried keeping my processor at stock clocks to see if it would help with power draw. No dice.

Anyone have any idea why this would be happening?

This actually seems to be a common issue - at least I've seen it on the forums once or twice with no real response.

The power block on the P370EM is 300w. Should be no issue there.

The only things I can think of are:

-The GPU temp is actually hitting 90c but my monitoring programs are inaccurate.

-Power draw from other components are causing the GPU's to throttle.

....Pretty lost.

I will say that I'm not too concerned as my in-game experience is great. I am just curious on the benching results.

Any thoughts?

mine was the same original but i found the 33 10 better. I dont understand, if i use the 33 10 stock without OV and clock it to +130 / +600 i get higher score than if i use a OV 1.025v or 1.05 and clock to +230 / +600 wtf? i mean i got the P150EM with the 180W PSU and i dont have a XM cpu just a 3610QM shouldnt i have space to Overclock? why am i getting lower score like 200-400.

EDIT: +130/550 3dmark vantage 24800 score and 3dmark 11 P7255. I have the 7970M aswell and it scores higher ( 26k vantage) with the same Notebook, well its optimized for benchmark probably. Well i dont know why my 680M doesnt work well with higher clocks (OV) its getting around 80C°while benchmark and while gaming farcry 3 85-90C.

Strange... more voltage e clock.. e worst benchmarks... and in real world, fps games? is worst too?

Are you using 33.10 MSI?

I'm having the same issues.

Clevo P370EM. 680SLI. Used the Clevo BIOS 33.10 OC, 980/1200 stable. 12.5k 3DMark11. 80c max BF3.

Upgraded to the Clevo BIOS 33.10 OC/OV 1.025 and 1.050. Same clocks. 11.9k 3DMark11.

Only issues in 3DMark11, In-game I seem to have zero issues at increased clocks, however I'm a bit anal and I'd like to bench as high as possible knowing that everything is running aOK.

Should I try the MSI version of the BIOS?

Other thoughts?

Voltage is fixed on the mobile vBs Mods, so 3D Turbo voltage will always be @ 1.050v.

Thanks, Prema. I noticed it OV'ed at higher clocks!

I'm now having issues with performance, which is very strange. My temp doesn't exceed 78c but the card isn't performing well even at 1050mhz/2400mhz vs. the 980mhz/2400mhz i was at without OV.

While playing BF3, I have no issues. When I benchmark 3DMark11, my scores drop from 12.5k to 11.9k.

You will gain for example extended CPU Turbo Times and 1T. Also your 3740QM should already have 4 extra multis in XTU irc...

What's weird is that I went ahead and ran 3DMark11 with the OV Bios. Temps didn't exceed 78c and my score went down! Almost looked like it was throttling...Used GPU-Z to monitor. Very strange.

I tried reloading the non-OV Bios and scores went back up to the normal 12.5k. Scores dropped to 11.9k using he OV 1.050 version. Tried the 1.025 version with no dice as well.

Core was at 1020 vs. the 980 I was testing with the non-OV Bios.

Wondering if the updated 320.18 drivers are the issue.

Messaged slv7 to see what's up!

90°C is way too much for a 680m, not even in my M15x I reached such high temps. Clevo seems to have some issues with their heatsink design, make sure that the heatsink sits fine and applies enough pressure on the GPU dies, 90°C sounds almost as if some modding is required. @Khenglish once mentioned that his heatsink wasn't completely level... which could also be a serious issue when it comes to temps. Or maybe there's a huge gap between cooling fins and fan... you'll need to take a closer look at this to find the cause of those temps.

Hey svl7, thanks for all your hard work.

I was using your modified VBIOS with default voltage and was able to get some good results.

I just now reflashed using the 1050v version. For some reason my voltage is still greyed out when using Precision X or NVIDIA Inspector.

Thoughts?

Thanks!

You need the Modded main BIOS too, to get your CPU up to task! >>> http://forum.techinferno.com/clevo-sager/3119-premas-bios-mods.html

Prema, I'm a pretty experienced OC'er, albeit working with desktops.

Right now I'm using Intel's Extreme Utility and was able to up my multipliers and adjust my memory timing to 9-9-9-24-2T.

Is there any reason I need to be downloading your BIOS update if I've done the above and I'm running an I7-3740QM?

Thanks!

Is there a modded BIOS for the P370EM? I agree with the OP as the BIOS is a little lacking. However, I don't mind using the OC programs that automate per Windows start.

Jesus! Almost $1k per card OEM?

I actually did some research and it seems that I have about 7-8 degrees to work with. I'm not comfortable with the temp. going above 88-90c consistently. Will load the OV BIOS when I can download!

1. because the high clocks you see are overvolted vbios,s and 2. the M18x has better standard cooling capacity..

Right now I'm running 960/2400 stable.

Temps between 78c-80c.

Running the P370EM.

i73740QM

16GB DDR3-1600

128GB SSD, 750GB 7,200RPM Data

SLI 4GB 680m

Around 12.5k 3dMark11 (Graphics around 14.5k) and 35k Vantage.

I'd like to hit 14k and 39-40k if possible.

Was thinking about loaded the OV bios but 80c, while healthy, is getting warm.

Thoughts?
