PREMA BIOS MOD Review

That's the same model...

 

Sorry for asking prema and therefor sound a bit impatient is the version for us W150ER users close to a release? since you mentioned you didnt own the model urself and all

 

YES, the W1x0ER PM2.0 version is next...I can't promise OV/UV mods, but OC will be unlocked as usal.

 

Hey Prema this is a very nice Bios Mod =)

But can you add the Functions Undervolting CPU?
Because my CPU it is very hot

And more Fan Speed Modes?
20% Fan Speed and 40% Fan Speed...


For W110ER Please

 

hey Prema

I Have some questions about the 2.0 OV bios.

I can't have more than 980 mhz on the 650m memory.With the 1.4 OV , i can reach 1120 mhz.

When i want to O/C more than +80 mhz , the drivers crash , but no notification , nothing , the gpu goes to 405 mhz for the core and the memory.

Have you don something between the two version that can cause this ? Is it possible to modify the Vmemory or something else ?

I tried to re setup the drivers , nothing. Have you a solution ?

I can bench the Ts bench 32M with 4 cores at 4 ghz : 7,561 secondes , 8892 for the cpu score in 3Dmark11 !

Thanks a lot for your work

 

CPU undervolting isn't yet possible on SB/IB processors.
Though you may reduce the processors TDP values (Long Duration Power Limit & Duration ) with the Mod to keep the system cooler.

Fan speeds are a lot of work (as the values differ from BIOS to BIOS & model to model)...also I am not yet able to code different speeds to different keys.
Sorry!

Happy that the CPU overclock works well for you! It also works on 3840QM (timsp8 just looked for the sliders in an other place. OC sliders are the "1-4 Core Ratio Limit" under "Advanced" "CPU Configuration". Also we have to use the full multi that we want to see 36,37,38,39 etc, not just 1-4)

I don't have those issues with PM2.0 OV version on my GT650M.
(313.95 driver, OC tested with NvidiaInspector +3dMark11)
Clevo updated the base vBIOS, but the volt hacks are "identical".

 

thanks for the answer

I tried to test with the lastest Nvidia beta drivers , and now , when the frequency is too hight , the drivers reset to the good default value , 835 mhz for the core and 900 mhz for the memory , but nothing about the memory issue. I can't reach more than 980 mhz , i use nvidia inspector for overcloking and 3Dmark to test rapidly the stability..

I'm not the only one to have this issue , a membre of HFR.fr (french forum) and maybe AscheWandler of this forum ( #4107 of the Clevo W110er Owner's Lounge) are at the same point as me. AscheWandler have artifact , not me ... that's the difference..

Have you test th Oo/c of the Gram with the 2.0 ? Maybe this issue is caused by the new clevo vBIOS v80.07.58.00.A1 ?

Thanks a lot Prema

 

Ah well I pumped the vRAM slider to my old max values of 1135Mhz and it crashed the system...don't know what NVIDIA changed with the vRAM, but we didn't touch that at all...
If nothing helps the OV version of Prema Mod 2.1 for W11 will get the old vBIOS back.

EDIT: SVL7 just gave us the info, that it looks as if the vRAM timing table was changed by NVIDIDA. So I would guess its running tighter timings now which in return reduces the OC potential of the vRAM.
Anyway if you guys prefer the older GT650M vBIOS, then it will be back with PM v2.1 OV EDITION for W11.

 

Is it within your expertise to loosen the timings? The gt 650m needs all the mem bandwidth it can get. If not i wouldnt mind getting the old vbios back for the UV version as well provided it is still uefi secure boot capable? this absolutely ridiculous on NVIDIAs part, CUDA memtest is reporting rampant soft errors even with modest overclocks of 50mhz.
God im even getting soft errors at stock which should NOT happen considering i run quite a few CUDA apps, accuracy of the calculations paramount.

 

Thanks one more time Prema

That's what I thought , can't wait for the 2.1 OV .

For the next Bios , was it possible to unlock few options like voltage of the gpu and the Gmem ? It would be nice , i expect goods temperatures with a little mod .

:hi2:

 

I am using Prema's awesome BIOS for the W370ET, but I appear to have no sound in Windows 8. It looks like there was a revised BIOS by Clevo to fix this specific issue, is there a Prema BIOS in the works for this new updated BIOS.

p.s. Prema, you rock

 

yes!

W110ER/NP6110 Prema Mod version v2.1 now on the blog

Changelog:

- Updated Clevo base to BIOS v1.02.11 & EC v1.02.07
- Downgraded GT650M vBIOS to v80.07.14.00.A6
(NVIDIA stock v80.07.58.00.A1 has a "vRAM bug")
- Enabled Configurable TDP for XM CPUs
- Combined EC & BIOS files into a single update
- New UOV EDITION = energy savings & higher OC

(UOV = All clocks undervolted & Turbo clock overvolted) Credit: SVL7

ENJOY! :hi2:

P.S.: I haven't forgotten about you W1x0ER & W3x0ET owners, but NVIDIA's vRAM bug needed to be addressed first.

 

Hey Prema ,

thanks to your new Bios I have one question about 2.1 UOV bios , how does it realy work ? what are the voltage when the gpu is no working , and when the gpu is on load ? At what moment the vgpu is increasing ? How can i o/c the card ? Because between the turbo and standard clocks , there is some differences that can't be handle by the increasing of the voltage i think.

Thanks

 

The UOV version is basically a hybrid. The 2D clocks are undervolted exactly like on the UV BIOS (exact voltage levels are on the blog). So it will safe us energy and keep the system cooler while we just want to watch a video or do other mild stuff which uses the GT650M, but won't require its full potential.

But, instead of having the 3D/Turbo mode undervolted as well, it has the 3D voltage of the OV version, so when we overclock the card we also have the benefit of reaching higher 3D clocks.

 

It works very well ! Thanks again Prema

 

This is pure gold, thank you very much for the prompt reply. There's a small pressie waiting in your Paypal

 

I may have to switch back the UV Version of your latest BIOS. My W110ER draws around 140 watts from the wall under full CPU and GPU load and has some strange issues with it. When both are under full load, the CPU will draw 39-42 watts and then cause the GPU utlilization to drop to 67-70 pecent causing games to lag. The minute I take the load off the CPU (via burn in test) the GPU jumps back up to 99%. Another thing, if both are left loaded (Folding) the CPU will VERY slowly drop to 23watts after being around 39-40 for about a minute. I have seen this in games too and over the course of a couple miuntes the game will start to lag horribly. I have tested it overclcocked and stock..Never had this issue with the UV bios. I am sure going to miss the overclock of this bad boy though..Has anyone else seen this? I am sure we are just hitting a power limitation that HT says these laptops have. I could not believe I saw it draw 140 watts! This was with the battery not installed by the way.. For reference, my coworkers Dell M6600 draws 170 watts under similar conditions.

EDIT: I just noticed that it now idles around 30 watts where as before it was idling around 16-21.

 

Here are some benchmarks for the CPU OC.

My w110er - 3840QM, 8GB Kingston Hyperx, Samsung 830 256GB, Prema 2.0 OV bios. Ambient room temp was about 70F-75F. My laptop idles at about 60C. No external cooling used.

I used 3DMark 11, WEI, and Passmark Performance Test - PassMark Software - CPU Benchmark Charts. Temps were from HW Monitor 1.21, highest after the test was run.

1 note - on the Passmark website, the 3840QM is rated at 8900. I ran it when I initially installed W7 about 1 month ago, and got 2807 overall and 9027 for the CPU. My scores today were much lower at stock. Dont know what affected it, if anyone has any ideas. It also doesnt use the 650M for 3D.

Sorry about formatting.

I think it makes a huge difference. Thanks Prema for the bios mod. Just saw 2.1 was posted, going to download it now.

 

Mine idles between 8.5w-16w with the same version. Your NVIDIA driver doesn't shut down the GT650M it seams. Try to reinstall the latest driver 313.96 and make sure no software is forcing the use of the GT650M

@timsp8 sweet, but those temps are a bit high, we should keep them under 90c for. Did you use the FN+1 function during those benches?

 

With my 3840QM , 8898 on CPU score of 3Dmark11 with a ratio core limit at 40 , 7.33 on cinebench.
Before i was at 8000/8050 approx..

 

i didnt force the fan on high. i wanted to see what it would get to on its own.

i have a notebook cooler that i modified with a case fan that has higher airflow. it normally idles at about 40C and gets up to about 60C in games. i didnt have that fan on during the benchmarks, but i use it every other time.

 

New 3DMark results:

Core Ratio Limit at 42:
Ice Storm - 73125
Cloud Gate - 8364
Fire Strike - 1358
Fire Strike Extreme - 651

Core Ratio Limit at 42 and TS set at turbo:
Ice Storm - 84609
Cloud Gate - 9276
Fire Strike - 1362
Fire Strike Extreme - 652


It still made a difference. I had my external cooling set at high this time, and the CPU jumped to 95C at times. The internal fan was running on high most of the time too during the tests.

 

Hey there,

I have W110ER Prema Mod v1.4.

Should I update to W110ER Prema Mod v2.1???????????



What's with the "Downgraded GT650M vBIOS to v80.07.14.00.A6"???? (updating BIOS will downgrade GPU's Bios too??).

Instead of downgrading, Isn't there any newer Vbios from Nvidia that would Fix that (Couldn't you officially contact Nvidia???).


ps: I don't believe in downgrading Vbios, because how can I be so sure that instead of increasing FPS from updating, won't it actually make some games to even have less FPS's because of downgrading the Vbios (and maybe some problems with some Nvidia Driver versions).

EDIT: , I already have Nvidia Vbios on version: "80.07.14.00.a6". God damn it, now I can't live knowing there's a higher version . (PLEASE CONTACT NVIDIA to see if they have a newer version than the bugged one).
Keep Cool

 

Clevo introduced a new vBIOS which causes artifacts (one person had them even on stock clocks) and lowers the OC potential of the vRAM.
I just put the old vBIOS back in. So v1.4 & v2.1 use the same one on W11.

BTW: Sending final test versions of Prema Mod v2.1 for W150ER & W170ER to tester...

 

Thats great news!!!

 

But wouldn't that bios actually make you have more FPS?

And that one person couldn't by any chance be a "one of a kind case?" (maybe bad manufactured GPU????).

But do you know if Nvidia actually have an even updated Vbios than that one causing probs?? (It would be awesome if you could contact them).


BTW I flashed with your Bios 2.1 (THANKS AGAIN:thumbsup .



ps: Do you have the stock Vbios version that I could flash? (Wanted to test)
Keep Cool

 

Overvolting possible in this version ?

 

Everyone complained about that vBIOS, just download the stock 11_07 BIOS & EC from my site and raise the vRAM OC slider...you will see that you won't reach nearly as high as with the old one.

@ xanyanou not today

thanks man, good job

 

nevermind, seems to be a problem with the heatsink.

 

I was one of the people in question, the new vBIOS didn't seem to bring many noticeable improvements but the most noticeable drawback was the highly unstable tightened vRAM timings at the stock frequency of 900mhz. This is no mere faulty GPU as the problem specifically manifests with the vRAM system.

Basically, you probably know well that system RAM stability is partly frequency and partly latency. Tightening latency doesn't really improve situations where raw throughput is required (i.e. GPUs which tend to stream info from a single dataset) but the potential for instability increases.
In theory, yes the new vBIOS could bring more FPS through the tightened vRAM latencies but you gain much more by OCing the vRAM clock (if FPS was important to you).
For me, stability is the most important metric, there is no point putting up with random crashes while gaming as you totally lose immersion.
You can only truly test memory stability with very sensitive software like CUDA memtest as human eyes are unreliable at spotting artifacts.
Granted, the vRAM instability is difficult to detect in most normal usage scenarios but it becomes very obvious with CUDA memtest. With the old vBIOS I could clock to 1200mhz memory with an error rate from CUDA memtest of 1-2 per pass. I was getting the same error rate at stock with the new vBIOS. With the 1200mhz OC, I could game on Shogun 2 but there would be infrequent crashes about 6hrs apart. One can deduce that an error rate of 1-2 per pass is roughly equivalent of 6 hrs of Shogun 2 stability.
I'm certain it is the new vBIOS since I'm back to zero CUDA memtest errors now with the version 2.1.

 

i have a 3610Qm here and am running prime95 atm with throttlestop enabled. temp is at 81 degrees for both CPU and cpu package and the cores are the same. im also on the PM 2.1 here so im not sure whats the problem with urs then.

Why would you consider a 3632QM then do those tend to run a bit cooler?

 

Definitely a problem with the heatisnk, corner seems to be in contact with the package.

The 3632 runs cooler but at the cost of lower frequencies(2.2-2.9 typical) vs the 3610qm (2.3-3.1 typical). And it is also $100-$150 more for OEM new/used. Might as well just use ThrottleStop. I had first assumed it was a change in the manufacturing process that made it possible, but I suppose that's impractical.

 

Just threw a few more bucks your way Prema. Thanks for your continued support.

 

+

Well, Yes. I'm aware of that. But the problem is that the PC idles at around 70Cº and goes to 90Cº easily, I wouldn't ever make OC in it (Only throttle stop for the CPU that helps a damn lot on BF3 and removes all the lag with the I7 3610 QM).

I will only make OC when someone get me a new CPU\GPU cooling block for this


I'm playing The "War-Z" and have all on high (W110ER) and shadows and one more thing on medium, but it's sad that even with the GT650M, it goes to 12FPS . (I know, the game is still not optimized... but it SUCK).


The only time I could really OC like HELL, is when I remove the bottom cover and use the good efficient thermaltake laptop cooling pad I have with a huge fan, the GPU idles at less than 30Cº . But it also suck, since the grips go away with the cover too, so the laptop is always sliding .


PS: But nvidia on newer vbios tend to always improve the coding and patch new things to make the gpu even faster than just driver improvements, that's why I'm always thinking what would be my FPS on newer games on latest Vbios?? (Some times they can lower a lot the mhz, but make the gpu 20% faster, even though there was smaller clocks. Sometimes they even disable\enable some components on the gpu to improve either stability or speed of coding).
Keep Cool

 

is there a complete tutorial for using the mod ? i cant seem to find an in- depth tutorial for it

 

Hi prema any news on the OV front for np6165/w150erx? You've done great work will pitch in a bit if there's a chance to get an OV mod.

@notanutcracker: go to prema's website and you can see a tutorial there for the bios mods.

 

FLASHING GUIDE « Prema Mod

There are also most functions explained on each release page, have yet to find time to update that info though...

BTW: Prema Mod 2.1 beta for W370ET/NP6370 & W350ET/NP6350 now with testers...

EDIT: Got ninja'd by feelseasy...we will look into OV

 

You should repaste your CPU and GPU. I had a problem with temps too and repasting solved them.

 

W110ER doesn't run as cool as the W150ER, but given those temps, you will easily knock off 10C by repasting with Prolimatech PK-1 which is one of the best thermal compounds. Of course other compounds will reduce your temps significantly too. You can go liquid metal if you want to increase that even further, but you need great contact and no gaps.

GPU on my W150ER runs a lot cooler than my CPU usually, so I put mini heatsinks on the GPU pipe only to hopefully hold more heat to let the CPU drive more of its heat faster to the vent, this actually improved my CPU temps 2C in gaming and GPU still runs cooler.

If you're running with stock paste job, then that is the problem, some resellers do horrible jobs at pasting.

What would be cool is to mod the bottom panel and drill in fan intakes/outtakes, and being able to screw it on.

 

Yeah I know that. But the laptop rarely reach 90Cº so I won't change the thermal compound yet.

But If I ever change it, I will only use Artic MX-4 (I have been using all the Mx series since the MX-2, and liked it a lot. I still have some MX-4 here).


I wanted to also add little memory cooler in the GPU\CPU cooler, but there was a guy in this forum saying he was going to make a full coppe bigger replacement cooler, I'm still waiting for it .
Keep Cool

 

He's going to sell you it? I don't quite understand. Can't go wrong with some memory coolers though, in the right place it does wonders, I would advise against epoxy, though.

 

I added a twitter page to the blog to keep you guys a little better informed about what's coming up next:

Thanks Prema for another awsome release.
Just one question, has anyone had success installing win8 with uefi? So far I can't boot the usb drive to install it.
I already formatted it with fat32 and copied the win8 iso content to it. The problem is it doesn't do anything when I select the usb drive using F7 boot menu.

 

You first have to set the BIOS to WIN8 and enable secure boot then it will detect the .EFI file on the stick and boot from it.

 

Already did that:
OS-> Win8
uefi boot -> enabed
secure boot -> enabled

When I try to boot from usb drive it just go to setup menu again. And it doesn't seem to recognize the efi file in usb drive because it doesn't show "Windows boot manager", instead it shows "uefi: generic mmc".

I also tried this guide: http://forum.notebookreview.com/sager-clevo/695285-how-clevo-usb-efi-install-windows-8-a.html
But the same problem occurs. I even tried with Win7 iso to make sure it wasn't some problem with my win8 iso.

p.s.: I have the Clevo w150er, not the 110er

 

Try to just set Win8 mode and leave secureboot disabled...

 

Hi,
Could someone explain how to use the core ratio limit on the i7 3520M please ?
