Hey Guys! Will there be a firmware for the 880M posted anytime soon? Any way that I can help?

Thanks!

Will you guys be working on 880m custom vbios as well?

Maybe someone else can give you some ballpark overclocks for that. In the meantime why not just try upping the voltage a notch or two & then seeing how high you can push the clocks without crashing or artifacting, while keeping an eye on temperatures. Then you could post back here saying what your stable overclocks were for gaming, which will help others like yourself when they read this thread.

Well, I am a bit of a newbie at this. Last night anytime I raised it over +130/+300 - even bumped voltage to 1.025 - heaven crashed/black screened (ie 135/300) I just know that even for synthetic benches a lot got higher than that. So I am concerned I am doing something wrong - like I am not sure at what point I should start tinkering with voltage. When it was crashing, I was at around 68-70C. I know temperature isn't everything but it just was odd to me that I have seen numbers of like +200/+600 for benching and I can't even do that. Again, I know no two will oc the same - it just seems kind of like a huge margin. That is why I was looking for insight.

Also, I was using EVGA Precision. Not sure if that will make much of a difference.

I don't have a 780M, but know a little about it. The stock voltage is 1.00V at 850Mhz isn't it? I was going to say don't go any higher than 1.05V, which is what I run my card at, but my card uses close to 100W at 1.05V, so your 780M at 1.05V would probably use close to 1.5 times more Watts than mine based on the number of shaders your card has. So, if yours was at 1.05V, then I estimate each card would use about 135W. MXM slots are supposedly rated for 100W, but I don't know how dangerous (if at all) it is to push them above the 100W ceiling for extended periods. I've seen people bench 780M cards at up to 1.1V, so they would be using over 150W per card, but that's only for a short time. I should think 1.025V would be OK for extended use provided temperatures are good, you definitely want less than 90 degC, and ideally less than 80degC. This is just my opinion though, based on the things I've learned & read, so it's your judgement call.

Thanks for your response, Robbo!

Yes, you are right on the stock numbers. I want to give it a little nudge for gaming - I have read through a lot of threads of benching but not many really give good insight on what they use for gaming situations in terms of overclock or higher voltage. Perhaps someone can point me at what they run? I know the whole "no 2 chips are the same" thing applies...I just want a realistic goal that CAN be ran for longer periods of time. Can someone point me in the right direction? Thanks

I just recently started dabbling again. Can someone tell me what the max "safe" voltage is for 780m (in sli if that matters)? I am having trouble going past +100 and +250. Temperatures are fine, but I get black screen/driver crashes at anything beyond that. Would that be a voltage issue? Currently at stock volts using stock drivers - with SVL7's wonderful bios!

Thanks for your help!

Is there any mod at all that can allow the NP9390-S to use a 120hz screen yet?

Time to tinker! I have the [h=1]Sager NP9390-S (Clevo P375SM)[/h]

I know this may be a loaded question but, What are the mods Prema's bios brings to this machine? I am unclear of which ones apply to it. I enjoyed Prema's product on another machine - I look forward to trying it on this one!

Thanks Prema! Can you check your PM please?

These are the latest 'Stock Clevo BIOS & EC' files combined into a single flash!

Make sure to select the version for your model and follow the flashing guide!

Please use the recovery guide in case of problems.

ENJOY being up-to-date!

P.S.: I am constantly collecting the latest versions to improve my mods.

In case you come by any newer files or a vendor specific version from Metabox, Sager etc, kindly post them here!

Yeah I think I can get you one tonight. Been taking a bunch of pictures for my other project...

I used some copper flashing and other scrap metal. I wedged metal under the edge of the heatpipes that runs out under the steel retention bracket to hold to bracket up for each screw. Then I made shims for each screw to widen the area they pushed down on. You can probably get away with a much simpler solution of just big shims that reach well into the plate to push down directly.

The idea behind lapping in this case is not to make the heatsink smooth, but to just make it level. Smooth is nice and helps a little, but the big deal is making it level. This gets a 10C+ improvement on clevos due to how they smash the heatpipes into the plate, warping the plate. If you look closely you can see stress marks on the die side of the copper late directly under the heatpipes. For the GPU I used an edge of a stone countertop to get between the mounting brackets. For the CPU I used the countertop itself since it does not have brackets poking through (which may not be true for the P370EM).

It sounds like you are getting poor die contact. If you have good die contact almost all the paste should be squeezed out from between the die and heatsink so that the die looks almost bare when removing the heatsink. I'm guessing that the paste needs to be very thick to make it between the die and heatsink so that you can't see the die at all after heatsink removal. If so then you need to increase pressure on the heatsink. This can be done by placing wide shims between the heatsink and heatsink screws so that the screws push down directly onto the heatsink instead of indirectly through the very thin steel.

In addition clevos heatsink assembly process is a bad one that warps the processor contact plate, but this issue affects both GPUs and the CPU, so it should not be the cause of your temperature discrepancy.

Is the fan on that GPU kicking up? Any dust in the heatsink for that GPU? Can't think of anything else.

It appears to be running fine, and I have gassed her out with the ol' can of air - I am going to try reseating with a different thermal paste. I mean, I have only heard of it happening - but maybe I got a bad tube?

Does anyone have a link for the stock 680m Clevo firmware? I need to go back to stock - thanks!

780m runs hotter, it has a higher default voltage and higher default clock.

Which cards are you referring to?

I asked this previously regarding the 680M but I recently bought a Sager NP-9390. Since these cards run much cooler than the 680m cards did, is it more feasible to game with mild overclocking? Thanks!

(Also, I am aware to monitor temperatures and what not - I just want to know what others have experienced!)

That's great work on the unlock for the 780! Still waiting on the Sager 9370s to get support for the 780...Dear Clevo, FASTER!

But meanwhile, I think this was overlooked (or perhaps no one knew) in my last post: Does anyone actually game with their 680m (I am running SLI) overclocked? Or just use it to bench? IF you game that way, what have you found to be comfortable? Or is it different per game? I have pushed mine for benches but saw the temps in there and didnt trust it for gaming!

It's been a bit since I checked back in on this forum. Does anyone with a 9370 680m SLI actually game with any overclocking? I found my temperatures were too high to trust it before - so I was wondering if anyone else had any revelations or found a comfort zone I could aim for? If so, what vbios, drivers, and overclock are you running? From what I can tell of picking through the 200 pages here, a lot of people game at stock speeds.

Thanks in advance!

Thats a Sager 9370, of course. Anyone at all?

Also I see a lot of people here talking about lap coolers, those things never really seemed to help my temps not even by 1 degree C. The best move I made was making something to lift the back the machin abouthalf an inch. That brought temps down a little. Has anyone found a cooler that actually suits this machine? Thanks!

Nope, but it's always fascination to hear that things appear to have changed which where never touched.

I am already maintaining dozens of BIOS versions and won't make T2 versions for all the P-models as that is what the stock BIOS does...

I have made one for your case though as no one else seams to have an issue...PM me as soon as you can and I'll send it to you. Also there won't be any BIOS menu unlocks for the EMs, too dangerous to try doing that on a system that I don't even own.

Aw, that's sad! But understood. Any idea how I can maintain my XTU overclock through power cycles/reboots? I seem to have to load the program each time I reboot - or is this par for the course?

I sent you a small tip for a beer on me! Thanks for all the help. Also, where can I twist arms for those hidden menus on a 9370?...haha.

So I used Intel XTU and pushed everything up 4 - everything seems smooth as butter. Hottest temp I have seen with benchmarks or stress tests is about 79C. So that seems great! Thanks Prema! But I have more questons! And don't worry, I will send some beer change your way soon! Just waiting on PayPal to correct an eBay issue - the ticket got closed today so I should be set soon =)

Anyway, the values don't seem to be loaded on startup and I see no option to set that. With it running at that temp, I feel safe keeping it there. So is there a way to load the OC values on boot?

Has anyone messed with ram overclocking any?

and last but not least...I am not familiar with things like Turbo Boost Power Max and Turbo boost short power max. there is also the time limit, voltage, core current limit...is there any reason to change any of these values? I have only overclocked an old Q6700, i5-2500k, and i7 2600k desktop processor So this is a learning experience! So if there are any tweaks laying around out there that anyone has advice on, shoot them my way! Sager NP9370 is my poison...

Okay I installed the Prema magic - is there a guide somewhere or some pro tips to overclocking the 3740qm? Also, how sensitive is it's temperature? Like will there be a general overclock I can just keep or something I have to monitor being I am on a notebook? (First time doing all this jazz to a laptop!).

Thanks!

Hello @Prema! I am fairly new to posting on these threads and keep toying with my new Sager e9370 =). I was curious, what are the benefits to running your bios over stock?

Edit for clarity:

I read the first post of the thread that tells me your changes. I am just curious what they actually benefit in newb terms? Ha!
