Sony Vaio S Bios Mod For Gt640m Le

You wont be able to install as it will complain the version you have is as current as the one you're trying to download.

The install of this mod is simply double clicking on 1 .exe and waiting a moment, then rebooting. Done.

To revert, you must use the other custom one (KeplerMod-STOCK - it doesn't care what version you have), this one will flash you back to stock. It is also a matter of running one .exe and rebooting.

If you can install any software at all, you can perform this mod.

 

I don't do much gaming at all really, but I'd like to be able to run my games on 1080p when I do. Which bios mod would be most appropriate. Should I just go for the 950mhz one? Or is the 735mhz a happy medium? I plan on using graphically intensive programs (like games) 1 time per month.

 

The modded BIOS works exactly like stock when not using the GPU, so you might as well go with 900/950/1000 so when you do play a game you are getting the most performance for gaming.

 

It's possible to play games whit ventilation balanced? Priority to ventilation it's so loud!!!

 

I've read all 26 pages of this post and I'm very convinced that the Modder and Amal did some great work. But my only question is about stock speeds of 135mhz. It seems like a headache, people are having to always run GPU-Z and MSI to get the 640m to deactivate and let the hd4000 run? I'm going to be in classes that require me to go without a charge for 3-4 hours. Its also intensive lectures so I can't be fiddling around with MSI AB trying to figure out if my damn laptop is sapping my power for no reason. Has this problem been resolved and stablized?

Thanks.

 

I think if you run neither GPU-Z or MSI AB, the 640m will deactivate and the integrated graphics takes over

 

can anyone confirm this?

 

Yup, mine is like that. I used the 850MHz version though, it should not be any different. I'm more wary about temps since I live in the tropics and ambient temps go up to 35-37 deg.C daily

 

Anyone try out BF3 at 900p and medium detail settings with the new OC'd bios? If so, what FPS do you seem to avg?

 

Hi Guys,

anyone got any idea about the nvidia driver? it seems that when i did the 3dmark benchmark...at the results page it says that my graphics driver is not approved.....and getting a bit low results compared to the ones everyone is getting...

NVIDIA GeForce GT 640M LE video card benchmark result - Intel(R) Core(TM) i7-3520M CPU @ 2.90GHz,Sony Corporation VAIO score: P2094 3DMarks

 

I've been playing quite abit of BF3 on my VAIO and I've noticed that the big maps run alot smoother than the cqc ones with the gun game. I've also noticed very little difference between the visual quality between low and medium, so I've just kept mine at low at 1600x900 and on the cqc maps I usually get around 40fps with a 900MHz mod. It can drop into the 30's but only when alot of stuff is going on and I'm moving quickly.

On automatic settings the computer defaults to much higher settings, and can usually run pretty well on big maps, but its frustrating on cqc. I leave it on low, the game still looks great.

 

This thread is basically the reason I am going the buy the Vaio! Assuming that I do buy it of course. I'll know for sure in about two weeks haha. Thank you Amal77! (and svl7 from TechInferno of course, although he may never see this!).

Just to check, is there any technical difference between the mods? or is it all just what ever clock speed appeals/is best for the user (and of course who made the mod)?

 

If the driver is beta, it will say not approved. This is normal and nothing to be concerned about. A long time ago there was a big deal about drivers cheating on 3DMark and so now Futuremark "approves" drivers but really nobody cares and it doesn't affect anything.

 

Hi rubbateckie,

The reason why we comeout with different MOD is due to the Boost features not working on our card.
It also currently cannot be OC through software method.

Like normal method of OC, different Card may give different Overclocking results especially in stability and temperature.

So, you have to test and see which MOD suits best to your needs.

From the testing I did, I can say that temperature will definitely increase, but still within the safe range.
It increased around 3 to 6 celsius from stock on stress test, depending on which MOD is used.

Hello,

It's not really working on my computer :
I launched a 3DMark11 benchmark with the original config : 1360

then I flashed my bios with one of yours (900mhz), new benchmark : 1550
I expected something like 2200, so i checked my nvidia control panel and yes I forgot to set the Manage 3d Settings. (high performance nvidia processor/Prefer Maximum Performance for the Power management mode)
I start a new benchmark, it seems to work the fps has increased but then after 5-10s it descreased to a very low fps ! like if the nvidia graphic card stopped ...

anybody has an idea ?

thank you.

 

"
ADDITIONAL INFO 2:
Currently there is a bug with GPU-Z, it will make your clock stays at FULL even when not doing anything(gaming, benchmark, etc).

The only way for your clock to stay or goes back to idle(135) is by closing the GPU-Z when not using it OR open up MSI AB at the same time if you want the GPU-Z to remain in the background.

This will definitely saves your battery when you're not plugged in.

Proof and Explanation :
"

Could anyone explain this problem? If I install the mod the graphic card won't go on idle automatically? And what is a GPU-Z? Please explain, thanks.

 

Does the "speed vs stamina " button effect this at all. For example if I ahve the 900mhz mod, can I just put the computer in "speed mode" then when I wanna save power, if I switch it to "stamina" will the 135mhz clock take over?

 

That's not at all what the posting said.


IF <------------ !!!!!!!!!!!!!!!!!!!!!!

you run GPUZ, the 640m LE WONT clock down.


Flash the mod, the GPU will behave as it normally would

EXCEPT WHILE <<<<------------------------- !!!!! ***** !!!!!!

you run GPUZ




and as for what GPUZ is, if you're asking, you don't need it. If you think you might, check out http://.com/?q=gpuz

 

Stamina switches to the IGP.

 

Have you tried "- To ensure the CPU/GPU don't throttle or revert to the HD4000 when gaming, open Vaio Control Centre and go to Power Management. Within the Power Management settings, under Cooling Fan Control, set the "Speed" setting to "Priority to Ventilation" ?

 

That was exactly the solution, thank you !!!!!

 

If you read the message very closely, you will see the bug has nothing to do with this mod. GPU-Z is a tool many people use to monitor what their graphics card is doing, you can watch voltage use, temp, memory speed, etc.. Problem is just by running this monitoring tool you're going to force your graphics card to clock up to full speed (stock it's 500, will be higher depending on your mod) and that's gonna heat up your computer, and drain your battery. If you need to monitor the temp of your graphics card, then run both, MSI Afterburner, and GPU-Z. If you don't need to watch the stats, don't run either and you're good to go.

 

woot ! ty!

 

Well the nvidia 304.79 beta drivers installed for me without the .inf hack, so that should be good news for anyone that doesnt want to tinker.

As for 3dmark scores compared to the stock drivers, it went from p2345 stock to p2333 with the new drivers. That update did a whole lot of nothing in 3dmark, but i'm sure there are other programs where gains will be more noticeable.

^^ those scores are at 1000mhz as well, with the quad core

I discovered something else about this driver. When in stamina mode it doesn't clock the gpu down, it just stays at 1000mhz. So i reverted back to the stock sony drivers.

 

Thanks for the info! In this case i'm gonna install it, don't use GPUZ anyhow xD.

ONE LAST QUESTION. I noticed an increased amount of OC possibilities. Why should I choose which one? Why shouldn't everyone take the highest OC?

 

In some cases the highest OC isn't stable. My S15 is not stable at 1000mhz, games crash and the display driver stops responding. At 950mhz my laptop is fine though. The highest frequency will be different for each individual graphics chip, so it may take a few bios flashes to find the fastest stable one.

 

So I guess I should go for a safer option with my i5 1Gb 640m? I'll try it out!

 

where did u get the original driver? im using the beta as well and seems that when checking wei...stamina and speed sgive me same results...before it doesnt...

 

I have no idea, what is causing my low score on 3DM11 and Vantage. Im constanly getting around 100GPU points less in d3m11, than results posted here in equal clocks. GPU tests get millisecond hickups and that brings the score down. Im now sure that it is not stability issue, because even with 735/900 im getting those millisecond hickups. However 950/1100 is perfectly stable in BF3 and WoT. No hickups, no artifacts, just perfectly smooth.
Same deal looks to be at vantage, where im getting 7470 gpu points at 950/1100. Should be getting around 8000.

 

Maybe you can check your GPU-Z log?
When you notice the the hickups, 10 or more seconds after that you just press escape to get out of the 3DMark11.
Then have a look at your GPU-Z log, see whether got any hiccup in there.

 

The original driver is on the sony support site. Here's the link right here Sony eSupport - SVS151190X - Support

 

Everything looks good in log as well.
Not a big problem, since games are smooth, but i´d still like to know what is causing it. So far i have no idea.
Im going to run prime95 blend test all night, to see if its memory or CPU problem.

BTW. Could you make 975/1100 bios if its not too much trouble .

 

Here you go :

Do report to me for any issue.

Thanks.

 

So I found something strange. I am using the 950 version of the BIOS, and everything works when testing with 3dmark 11 (GPU at 950Mhz), but when I play SWTOR, the GPU drops down to 570Mhz. Before loading the game GPU-Z is reporting 950Mhz, but once the game loads it drops to 570Mhz. Any ideas?

Edit: forgot to mention that I did set the preferred processor in 3D settings and set power management mode to Prefer max performance.

Edit2: strange. Rebooted, and now it is 950Mhz in game. Not sure why. I have been rebooting all day, so not sure why this specific reboot fixed it. Oh well. 60Fps in game. Very happy!

 

Only on SWTOR?

Howbout other games?

Did you OC your card using MSI AB?

 

So far only loaded SWTOR.
Seems it is working now after the reboot. BTW, I am not doing any OC in afterburner(it's set to 0+). I have it open so I can see the frame rate and the freq, but that is it. An I supposed to do any OC in afterburner?

Thanks

 

Is it just me or does anyone else have to reboot anytime they make a change to the NVidia control panel, whether of it is to change the global or program settings.

Also, even though I selected the game under program settings and set the power management mode to max perf, it does not work. It may be specific to SWTOR because when you select the exe (launcher.exe) it comes up in NVidia as World of Warcraft (launcher.exe), but I don't have that game. So since both games use launcher.exe it may be confusing SWTOR for world of Warcraft, which is why it won't stay at 950Mhz and drops to 570mhz. However, if I change it globally it works fine. Just not sure why changing program specific does not work.

 

No, you don't have to OC it on MSI AB.
Sometimes it act weird if it detect core clock OC on MSI AB, coz currently the Boost features doesn't work.

As for the nvidia control panel, mine does not need to restart whenever I do any changes.

You're probably right about it getting confused with the WoW launcher.

I don't have SWTOR or any games with the app launcher called launcher.exe. So, I can't comment.

 

Works perfectly fine. Played BF3 for 1.5 hours just now.
Max temps: CPU 86C, GPU 78C, System 84C. My ambient is around +26C.
GPU is still currently the coolest component.
Im building a modified desk cooler for my S15. Its not easy and takes time, but as a result im hoping to get more than 5C reducement for GPU and CPU. I already tried a temporary solution and i got 3C off both in full stress test.

svl7 wrote that he knows how to raise voltage on GPU. I have asked him to make 1.05v 1100mhz bios, but he has not done it yet.
Hopefully soon .

 

Good to know that it works fine.
Btw, today I tried myself to increase the voltage of our GT640M LE. Unfortunately it didn't work. hahah.
Better leave it to the pro(svl7) I guess.

Mind sharing your temporary solution you tried there?

Btw, have you found out what's been causing you the hiccup(low 3DMark scores)?

 

Hi guys. I'd like to share my findings of the S13 BIOS mod.

First off, I'd like to thank Amal77 and svl7 for their hard work and effort into both creating this BIOS mod and their forum community work.

I received my S13A a few days ago and installed the 900mhz BIOS mod created by Amal7 today. Here are my findings in my preferred stress tester and benchmarker, BF3.

All settings are on medium, except textures are on low. My resolution of preference was 1366x768 (1600x900 was too small for my liking). AA post and deferred are both off, and AF is on 1x. For both tests a game of conquest large was played on Operation Firestorm with 64 players. It is summer here in California, and my room has been 27 degrees Celsius for the past 3 days.

Without BIOS mod: FPS ranged from 30-50. 50 while idling at base, 40 when driving around or capturing bases, and 30 in smoky areas with intense combat. Max VRAM usage was 440. Max CPU temp was 78C, and max GPU temp was 71C.

With BIOS mod: FPS ranged from 30-75. 75 while idling at base, 50-65 (usually around 60) while driving around or capturing bases, and down to 30-35 in intense combat. Max VRAM usage was 460. Max CPU temp was 85C, and max GPU temp was 78C.

Overall I am very happy with the additional performance, and it is extremely noticeable in BF3.

 

^ this is off-topic, but if you want more performance out of BF3, create a file named user.cfg in the same folder as bf3.exe and put the following line in it

 

Thanks for that. That modification gave me an extra 10-15 FPS. Amazing what so little can do.

+Rep

 

Nice info.
Glad it work well.

Btw, is BF3 bottlenecked by the CPU?
Will we get significant results using a Quad Core vs Dual Core?
Coz when I play it on my Quad Core and 6970M, I can game it on Ultra Settings on 1920x1080 without any issue.

What does it actually do?
Will it reduce the graphics a lot?

Thanks

 

I actually think that there could be a slight CPU bottleneck in BF3. I usually get 60 FPS while playing thanks to the above modification, but every 30 seconds or so my FPS instantly drops to 30 and creates stutter for around 1 second, then my FPS goes back up to 60. This is very annoying while in game.

I doubt it is a throttling issue since my CPU does not go over 82 degrees and my GPU stays under 75 degrees.

Are there any good CPU monitoring programs that have graphs like GPU Z? CPU Z does not have monitoring unfortunately.

Also, it is NOT a VRAM issue since VRAM rarely exceeds 430 MB in BF3.

 

You can use AIDA64.
Just open up the system stability test.
Do not start the test, just use it to monitor your CPU
It will also show you if there's any throttling.

 

Thanks, I'll test it out tomorrow. Going to go to bed, I have to work tomorrow .

Even if it does throttle, there is no way I will ship this laptop back for the S15 with the 3612QM. The laptop is too big for my needs.

 

Same goes for me.
I need the portability.
Else would've go with the S15.

 

it does not reduce graphics quality at all. DICE has designed Frostbite 2 with with the single-player campaign and multiplayer maps like Metro in mind and has optimized the deferred lighting technology in the engine for small spaces with many light sources (like the tunnels in Metro), using DirectX 11 compute shader path.

however, if you play mostly on open, big maps where there is ONE GIANT LIGHT SOURCE (that is the sun), then all that optimization for maps like Metro actually become a burden for the engine and reduce the performance. by disabling the Deferred Compute Shader path in the engine, you gain about 10fps.

i never play Metro and always play big maps like Caspian Border or Operation Firestorm, so that command is a gift from DICE to me which i enjoy every time i play the game
