Sony Vaio S Bios Mod For Gt640m Le

@Amal77 glad to see that your mod is up. i'm sure everyone appreciates the work you've done here. I don't know if i have the heart to push my GPU all the way up to 1050mhz, and knowing my luck i probably didn't get a chip binned well enough to go that high anyway. I might try this tonight if the other mods don't go up online but i will be sure to post the results of whichever mod i end up using.
EDIT: well i tried out the 1050mhz mod and as soon i started 3dmark the display driver restarted, looks like i'll be waiting till the 950 or 835 mods come out because my chip can't handle 1050 at all

 

No worries.

Maybe I'll release a 1000MHz version tonight.

Don't want to duplicate the MODDER's work since he already made it.

Thanks.

 

the numbers seem kinda random... is there any reason he chose 625MHz, 735MHz, 835MHz, 950MHz

also would it be possible to make a bios that would allow you to manually adjust the 625MHz, 735MHz, 835MHz, 950MHz speeds without reflashing... kinda like a list of options you could select.

 

Actually those numbers came from me.
I suggest the modder to test one by one.
Those numbers I got are from the existing clock of the GT640M and GT650M.
Wanted to see the comparison as well.

Currently we cannot manually adjust the clock until we can unlock the boost features.
When that happen, then we can manually adjust our clock easily using nvidia inspector.

 

I don't feel too comfortable going all the way to 1050MHz from stock, I have a feeling that's getting too greedy. Hopefully tomorrow the links will be restored.

 

1050 is pretty greedy. my laptop didnt like that at all so i'm waiting till the 950 bios mod gets posted and hopefully that one will work... otherwise i may have to go even slower. Too bad i didn't get a ridiculously good gpu in mine

 

I definitely don't want to break anything, so that makes me wonder, what is the weakest link? Is it the GPU temperature, or could it be the DDR3 memory? I just want the safest upgrade possible, even 950MHz sounds too good to be true. It's not awful on a stock clock, but just knowing how much better it could be keeps me interested.

 

I haven't got any response yet from the Modder.
Probably he is quite busy with something.

If the modder didn't response yet in 3 to 4 hours from now, then maybe I'll release another 3 version, which is 800, 900, and 1000MHz.

The more the merrier I guess.

Currently at work, no time for modding.

 

this almost makes me want to get a S13A now.. do you guys notice any difference in palm rest temperature? does it get uncomfortable under heavy load? and hows the fan noise? does it get any more noisy under heavy load as well?

thank you!

 

Guys,

Just updated the first page with my own MOD.

So, now there'll be 3 versions (900MHz, 1000MHz, and 1050MHz).

Please do report to me if there's any issue whatsoever.

Have fun!

Thanks

 

Is there an 850 MHz option? That would make the 640M le pretty much the same as the DDR III GT650m, but I suppose 900 MHz is close enough.

 

FYI some 650M is 950mhz(boost). Like my Asus.

Spoiler

 

Ok fair enough - I shall wait my turn soon. The 650m is a good midrange gpu and well it's going to be plenty enough for me, I'm still using a nvidia GTS 250 myself.

 

Hi everybody.
Amal, can you check the MD5 Checksum of my bios from s15 (Russian version) please?
I can't check it, but i want to try your bios mod
https://rapidshare.com/files/1369555299/EP0000268941.exe

 

Hi there,

Yes, it is the same.

 

hi amal why i can't send you pm? can you send me 950 original mod? [email protected]

tnx

 

Thank you very much.
Can you send to me 625MHz and 735MHz mods please?

 

Sorry, will only share it with everyone once the modder(svl7) shared me the link.

Thanks.

 

OK so i installed the 1000mhz mod and it worked flawlessly for the most part. 3dmark 11 went from P1400 to P2345. 3dmark 06 went from 8974 to 13367. These are both with the i7 3612QM...
temperatures in 3dmark were very resonable, the gpu was at 62 and the cpu hit 78.
I have no soul and thus ran furmark and prime95 at the same time. I kept furmark small at 320x240 to keep the gpu load around 95% which allowed the cpu to stay clocked at the boost clock of 2.8 on all 4 cores. the CPU got up to a toasty but not dangerous 89C and the gpu got up to a perfectly resonable 76C. Ran for 10 min without artifacts or problems and then shut it off and promised to be nice to my new lappy from now on. Those are my results, hope everyone else sees similar results

 

I'm having the slightly odd symptom that someone else was reporting, mainly that the GPU/Memory seems to be stuck at 950mhz/1050mhz (using the 950 modded bios obviously), even when the computer is "at rest" with nothing running other than the monitoring programme.

This has only started recently, like in the last day. Prior to that (but after running the modded bios), the GPU would idle at 135mhz and clock up to 950mhz when the GPU needed to - now it's always at 950mhz.

Are others seeing this? I use GPU-Z 0.6.3 to monitor the GPU frequency.

EDIT: If I run MSI Afterburner, then the GPU will clock down to 135mhz - the very act of booting up MSI AB allows it to downclock. As soon as I exit MSI AB, the GPU clocks back to 950mhz... weird?!

Petrov.

 

@Petrov That's very interesting. I've been running the 1000mhz mod that amal77 posted for a few hours now and my card downclocks to 135mhz and 405mhz when idle.

I am running the standard nvidia drivers that come preinstalled and all my drivers relating to video are stock sony ones.

In the nvidia control panel i have the gt640 set as the preferred chip and i have the global settings set to prefer maximum performance.

In your case, there could be an application open that is causing the chip to clock up, even if the gpu load remains at 0%. I would try setting custom profiles for applications that need high 3d performance and setting to prefer maximum performance for those, while leaving the global settings for power management at adaptive. Some background application is probably keeping the clocks up, or at least that is my best guess.

 

So just a quick question, how does the overclocked performance of this card compare to the 650M (specifically the one the Asus N56, which is apparently clocked higher than norma?)?

 

See the thread. There are comparison screenshots, and other goodies...

 

According to GPU-Z, my non modified GT640M LE is stuck right 499.5MHz, speed or stamina mode, power adapter or battery, it wont come to a rest. I've got chrome, skype, and gpu z open.

EDIT: Memory was also locked at 900MHz.

I just downloaded MSI afterburner and launched it. At first nothing changed in gpu-z, but after I focused on the afterburner window (clicked on it) I saw gpu-z read a drop down to 135MHz and 405MHz (memory). This is weird, and it has nothing to do with the mod. Note: When gpu-z said the speeds dropped, the fans also got quieter.

Now that I've shut off MSI afterburner the clock speeds cranked back up once I started using chrome.

Going to uninstall GPU-Z and listen to my fans.

I think GPU-Z may be the cause of all of this confusion. I can hear the fans cool down as soon as I close GPU-Z.

 

Yeah, I'm seeing the same thing. I'm wondering if HeyWitMarsh is on to something regarding application specific settings in NVC. I'm going to try a few things. By the way, I'm running the original 950 mod.

 

I've just reset my settings in the nvidia control panel, now when you say you've set the gt640 as your preferred, are you doing this speed or stamina mode?
Also, when you say you have the global settings set to prefer max performance, are you referring to the power management mode within the global settings?

I've also just reset my defaults in the advanced windows power options.

I'm 99% sure it's GPU-Z causing this. Sit idle for a few moments in stamina, then open gpu-z go to sensors page and watch the temps climb and fans speed up.

 

Gents, whether I set it to Adaptive or Preferred Maximum Performance makes no difference - either way the gpu clock stays at 950mhz, so I don't think it's that. I think Kardon might be on to something about Gpuz itself causi it to boost to 950 and stay there....although we still can't explain why loading MSI AB allows the clock to go back down to 135 even with Gpuz on and running... Hmmm.

Petrov.

 

Yep, I think it's GPU-Z too. Afterburner sensors are saying it's sitting at 135 for core and 405 for memory.

 

Oops, but now GPU-Z is reporting the same thing - 135 and 405.

 

And immediately after Afterburner is closed, it goes back up according to GPU-Z.

 

And wait, and let it run at the full speed in stamina mode for a few moments, then close gpu-z and do nothing-just listen to the fans slow down.

Anyways incase anybody was wondering the difference between the i7 and 3320 i5 in 3dmark11 here you go!
i7 3520M (taken from the first page of this thread)


Anybody have a benchmark of stock i7-3612QM?
Quad core vs dual core would be more interesting

i5 3320M STOCK CONFIG 500MHz


I'm glad I went with the i5, now I'm gonna go try the 900MHz mod.

I could tell it worked just by watching 3dMark go through it's tests!

 

Mine is a 3612QM. You can see the results earlier in the thread.

 

I didn't see one from before the mod, maybe I just can't find it. I did see yours after the 950MHz mod

BTW: BF3 is running at 1080p very nicely, definitely a noticable improvement.

 

Hi guys,

Just want to address your concerned on the Full Clock on idle issue.

IT IS the GPU-Z that is causing the problem.

If you don't open up any monitoring tools at all, your GPU clock will maintain at idle(135).

For example, without GPU-Z running for about 1 minute, then you bring up MSI AB, you will definitely see that the temperature have a slight increase because the GPU clock start to increase to FULL, but it only happens for probably couple of seconds, then the clock start to idle(135) back again.


Focus on the Temperature of the picture above, it obviously shows that the temperature was low(43c) when it started, then goes up abit(47), then goes back down.

But when you run the GPU-Z without MSI AB, the Clock didn't just went up for couple of seconds, instead it remains at full clock, unlike MSI AB.
It only goes down, either if you close it totally or you open up MSI AB while the GPU-Z is still opened.

Conclusion:
If you want to save your battery, make sure you close the GPU-Z or you open up MSI AB if you want GPU-Z to be opened all the time.

 

Very nice mod. I am using the 1000 Mhz BIOS with nary a stability issue. This makes my decision to choose the S13P over the Clevo W110 even better

Thanks!

 

Just tried the 900mhz mode on my s15 - works like a charm. Thank you so much for this.

If I format windows and do a clean install, would I have to reflash? Or not because BIOS is t affected?

Cheers.

Totally agree. Im selling my w110 after seeing this beauty, though I may change again when the u2442 gets released state side.

 

Ha funny that, I was waiting for he u2442 myself when I came across this mod and realised that the s13p would be perfect for me if I could over clock the gpu.

Ordered mine last night!

 

@Kardon403 All of my settings are done in speed mode. I have my global settings for power management as adaptive and my specific application settings for some applications set to prefer max performance. But as Petrov said it doesnt look like the power management settings make a difference.

If i run only gpu-z my clocks jump up to 1000/1000 for a few seconds, then drop right back down to 135/405, so for me gpu-z is not causing an issue. I also do not have gpu-z installed if that makes any difference.

 

i also had the problem of full use of my GPU in 1000Mhz mod but i solved it by passing my S13p speed mode in normal and not in high performance ^^

i'm here though for two other concern that i also asked to svl07 :

- first can we unlock the SATA 3 in this modified Vbios ???
- second can we unlock the PCI-E 16x because the GT640LE run in 8X (S13P)

 

I also have confirmed that GPU-Z will lock the GPU at highest speed if you leave it running. This is likely to be a bug in GPU-Z and not a problem with our laptops.

I played Diablo III for about an hour on the laptop, 1080p resolution with all settings maxed but no AA. I finally made it to Act III so I played the opening portion of the act during the Siege of Helm's Deep and it was just about flawless, averaging 45-50 fps during the part on the walls lighting the signal beacons. This is the first time I've ever owned a laptop which was really capable of gaming, it was a nice feeling doing it on this beautiful IPS screen.

Oh, I didn't save a 3DMark 11 screen from before the mod. Hopefully someone else with the quad-core can do a run before they mod theirs.

We'll need to find someone experienced in hacking the Advanced BIOS stuff in these BIOS. Maybe one of the guys who was hacking the other VAIO BIOS can help us there.

I doubt our GPUs are powerful enough where 8x vs. 16x will make any difference, even with the BIOS mod. Even very powerful desktop GPUs don't really benefit from the full number of PCI-e lanes. My desktop machine runs GTX 470 SLI and one of the cards is stuck at 8x because of my motherboard's PCI-e slot layout. I don't notice any difference there.

 

I went straight for the 1000/1000 MHz setup. I have the worst CPU (i5-3210M) and 1 GB graphics card:
Stock, P1356: NVIDIA GeForce GT 640M LE video card benchmark result - Intel Core i5-3210M Processor,Sony Corporation VAIO score: P1356 3DMarks
Modded, P2230: NVIDIA GeForce GT 640M LE video card benchmark result - Intel Core i5-3210M Processor,Sony Corporation VAIO score: P2230 3DMarks

Very happy with the increase, however I still haven't done anything to stress the computer more than 3DMark, so I'm not yet sure if it's fully stable at these clocks. My ambient room temperature of 27-28 degrees isn't helping, but the temps don't seem too bad. The fan certainly (and understandably) is louder after the modded BIOS, though. Doesn't really matter, it's not like I'll be gaming on this without headphones anyway.

 

Hmmm.. that's weird.
How do you check your clock without GPU-Z installed?
So, you're saying that your clock still runs on 1000/1000 for idle even when the GPU-Z is not installed?

You may also get tricked by GPU-Z if you open up 2 instance of GPU-Z.
Means that once you open up the 2nd GPU-Z instance, couple of seconds after that, your clock will also drop back to 135 EVEN without MSI AB.

I also noticed that if I open HWINFO64 after at the same time GPU-Z is opened, and check the GPU sensor on HWiNFO64, the clock will also reduced back to 135 after couple of seconds.

Sorry, what do you mean by passing the S13P speed mode in normal and not in high performance? ^_^

Yeah it would be awesome if someone can unlock the SATA 3 and the PCI-E 16x.

 

when you are in speed mode Go to control panel => power management => then you normaly can switch between 3 mode Normal\high perf\energy saver

in high perf GPU will always be at full range (ex:1050Mhz)
in normal it will adjust performance when needed

i just test GPU-Z and after a minutes it's a 135Mhz instead of 900Mhz for my bios !!!

sorry i'm french so i don't have Win 7 in english ^^

FACELESS i noticed a slightly difference between my GT640LE in GT650M mod (which run in PCI-E 8x) and the GT650M of a mate in a N56VW (which run in PCI-E 16 X)

so i think it worth the try , if we can win a little more graphic power ^^

 

The 650M is most likely using GDDR5 memory instead of the DDR3 in 640M LE, which makes it faster despite similar clock frequencies.

 

low life it's a GDDR3 GT650M on the N56VW !!! if it wasn't , i wouldn't have told that

 

With the BIOS modded 640, does anything change with the Stamina/Speed switch? If I put it in Stamina mode does anything change by running this BIOS? I guess energy consumtion goes up in Speed mode?

 

I see...
I've tried the normal mode(on mine stated as Balanced instead of normal). Still the same.
But when I try the Power Saver Mode, yes after about 10 to 20 seconds after that, it does goes back to 135. Also your laptop will be slow if you play games on that settings(Clock speed maintains but the GPU load reduced).
So, for me it is not the best method. I rather close the GPU-Z or run it with MSI AB, so that it wont affect my performance.

Maybe someone else can try as what Novokaine advise, and comment?
Probably it'll work to some.

As for the GT640M LE on PCI-E x8 vs GT650M DDR 3 on PCI-E x16, we can probably get some more SPEED from our GPU, but a voltage increase might be necessary(Our GPU run Max 0.925v on whatever high clock we pushed while the GT650M runs on 0.9750v on 900MHz and 1.0370v above 1000MHz).

It still work as per normal.
Just make sure your GT640M LE don't stays at FULL Clock even while using the Intel4000HD.
Workaround as what we all have been discussed, do not open GPU-Z or you can put it on Power Saver Mode(slow mode).

 

Shouldn't the 640 LE shut down completely when I flip the switch to Stamina mode? Is that not what happens normally?

So if I don't run GPU-Z (which I doubt I'd even install to begin with unless I have to) the 640 LE clocks down in Speed mode?

 

I've noticed that if I have MSI AfterBurner running even in stamina mode, the 640M LE does NOT get shut down completely and affects my battery life.

With the extra battery sheet, in stamina mode:
10+ hours without MSI AfterBurner running.
~5 hours with MSI AfterBurner running
