Sony Vaio S Bios Mod For Gt640m Le

I've created a 900 core/900 memory MOD last time, maybe you can use that instead.

thank you very much!!!!

 

I want to increase the GPU performance, but keep the thermal and power envelop as close to stock as possible.

Can you create a 735Core/900RAM mod? (the one by svl7 is 735Core/1000RAM)
Also another one for 625Core/900RAM?

 

Hi Amal,

THX 4 your great work! In the first post you did not mention the DDR clock at all? I did not get my S15 so far and that is why I do not know what the standard clock is of the DDR3 Vram. I thought that the memory will easily be the bottleneck, at least if you overclock the GPU. Isn't that right?
Did you check the vram as well as the GPU for it's (over)clocking capabilities?

 

Hi, got my S15 yesterday and I want to use the bios-modification. For fun I just installed gpu-z, and I can see that my graphic card only has 1024 MB DDR3. Is that correct? I thought it would be 2048..
The most important question is; will this bios mod work with my graphic card? Is there anything I have to worry about if I can use the mod?
Is this graphic card weaker than the 2048 version?

EDIT: Okay folks, I did some reading which was pretty useful It seems that 1 or 2 GB DDR3 really doesn't matter, and that the mod will work anyway. That is great news! The next I need to find out, and you can maybe help me, is which mod I should use. Would you recommend the 950Mhz mod in every case? I'm not going to play very much, but when I do I would like to get the best I can with this wonderful Vaio

 

Is there some progress on the OC with voltage?

 

A bit busy these couple of days.
Will post it when I have time to MOD it.

The Memory standard clock is 900MHz, most of the default MOD is MODded with a slight increase of 100MHz(1000MHz) since it is quite stable at that speed.
The highest clock without causing an artifact for mine is around 1140MHz. You may get different results though.

Yes, you may use 900MHz or 950MHz MOD for optimum(fast and stable) result.

Still testing.
What I can tell you is that our GPU might not be able to handle higher clock like the GT650M.

Tried on 1.0v(stock 0.925v), I can finish running 3DMark 11 on 1100MHz Core / 900MHz Memory. An increase of the memory to 1050MHz doesn't seem that stable. Might be our GPU limitation, who knows.

Will share with everyone once it is considered stable.

 

"The system bios is current, and does not need an update." I updated my BIOS with the original bios from sony.com, is that why the update fails?

 

I'm having a bit of trouble with this.

Tried both the 900Mhz and 950Mhz mods, GPU-z recognises the new clock rates, but when I bench it using 3D Mark, it has poor performance, scoring around 1500, and only recognising the core speed as 400Mhz.

Is there something I'm missing? I've switched the hardware switch to SPEED and also turned high performance on for 3dmark in the nvidia panel.

 

ADDITIONAL INFO 1 :
You may experience that when you run benchmark, games, or any application, but your Clock seems to be not at par as the Base clock.

Please follow the instructions
Nvidia Control Panel -> Manage 3d Settings -> Select the app you want to run full clock -> Select high performance nvidia processor on the option 2 -> Select Prefer Maximum Performance for the Power management mode.

OR

Nvidia Control Panel -> Manage 3d Settings -> Global Settings -> Select Prefer Maximum Performance for the Power management mode.
Now, all the app should run in Maximum clock.

You should be able to run at the full clock afterwards.

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.

 

Thanks but as I said originally, I've already set the high performance settings in nVidia..

 

Yes.

How about the "Prefer Maximum Performance on the Power management mode"?

 

... I tried to flash it back to stock with your stock file (R0142C5), but that is the same Bios-version that is already flashed. So I got the same message. Can I flash the oldest stock bios from somewhere? Thanks for your help, appreciate it!

 

You download it from here ?
https://rapidshare.com/files/2518519213/R0142C5-KeplerMod_STOCK.zip

 

Yes, and now I'm again reading the first and awesome post in this thread, and I find this:
Sony eSupport - SVS13A15GDB - Drivers & Software
Can I downgrade/downflash/flash to an older Bios version?

Edit: ok, that is the same version...

 

Did you run the InsydeFlash file?

By right it should just overwrite the BIOS, irregardless what version you're on.

 

No, I ran WBFLASH.exe... Thanks, I'll try it now!

 

Alright! Gpu-z shows nice results! And another question, is it always running at 950MHz when I'm in speed mode? (Or as long as the graphic card is active, is it always 950Mhz?)

Edit: bug with Gpu-z that keeps it running at maximum. Ok, thanks
Installed MSI Afterburner to verify that the clockspeed is normal when not on load, and it's perfect! Awesome mod guys, well done!

 

I didn't even know I had an account here, though that is off topic.

Amazing job, I got between a 10-25 frame increase in Arkham City with this.

If you feel like doing a bit more with this maybe you can try adding your mod to some of the advanced bios menus I've seen around.

 

Where do I find this setting?

 

Not my picture, just borrowed it from somewhere :


You can also set it only at the programs settings so that it won't always run at max for all of the application.

 

Have fun.

Currently we still don't have the Advanced BIOS Menu BIOS MOD for our VAIO S 2012.

 

Hmm.. set the above as well in the nvidia settings but still strange results.

Looking at MSI afterburner, it seems that the GPU idles at 900Mhz, but when I run 3DMark, it actually dips to 225Mhz while running the benches (memory dips to 450Mhz)? When I go back to desktop it goes back to 900Mhz, 1000mhz memory.

very strange...


EDIT: I'm using this on SVS13A1C5E, 1GB 640M

 

Found the source of the problem.

For future reference, VAIO control centre --> Power Management --> Cooling Fan Control --> Priority to ventilation.
Seems that even default "Balanced" fan setting for the SPEED switch, the GPU still freaks out and throttles itself if it goes above a certain heat limit. 60 degrees C maybe?

 

If you have been paying attention lately, the Priority to ventilation already been discussed and mentioned like a gazillion times to prevent throttling.

 

Ok this is a little off topic, but I want some options on this, I am looking at two models on newegg

Intel Core i7-3520M 2.9GHz, 8GB RAM and Windows Pro for 1399.99 after rebate.
or
Intel Core i5-3210M 2.5GHz, 6GB RAM and Windows Home for 1069.99 after rebate

Now the RAM is no big deal because I have a spare 4GB stick that I can use to upgrade the RAM, I will add my own SSD after the fact as well. Is it worth 300 bucks to move to the i7 over the i5? I figure the OS is a wash because I get upgraded to Windows 8 anyway for free.

I mostly play SC2, MW3, and Source games (LFD and Half-life, TF2), and a little bit of CIV 5.

Thanks, great work on the BIOS mod as soon as I order the laptop and get it in I will be doing this mod on it and to be honest this thread and form is the reason I am buying this laptop. Sony should be paying you guys referrals.

 

Not worth it.
Better save the 300 dollars and put it to use for something else.
Unless you don't mind offcourse.

I bought mine with the i7-3520M is because of the 1600x900 resolution. My country only sells a pre-configured Sony, no customize option. So, the only one with the 1600x900 is the one with the i7-3520M.
I need the extra room for my work.

As for the games you mentioned, I don't see any issue at all for this laptop.
Since our GPU now is as fast as the Stock GT650M, have a look at the benchmark below and focus your result on GT650M instead of GT640M LE.

If the Sony released the new BIOS for WIN8, you will create a new OC BIOS?

 

Most definitely...

 

in waiting for my svs15 to arive i have read through every vaio s 2012 thread in exstance and this one has been the most interesting. after reading i feel like a few things are abiguous... or have been answered but in a few different ways and id like to clear it up.

1) you we're testing over voltage mods, what ever happened to those. i plan on starting out with 975/1100 (though id rather have 950/1050) is that one over voltaged ?

2) when running the mod i know that it increases the boost clock, but i also read that it breaks the auto scaling, so when it runs it will run at 975mhz until it goes to sleep and sits at 135. so does it auto scale or not?

3) do we NEED gpuz or more importantly do we need afterburner to overclock. i remember amal77 saying that it is not needed but i read somewhere that this just raises the maximum overclock limit and that afterburner will be used to actually overclock. which one is it?

 

U don't OC with afterburner numnuts. The bios mod is the one that unlocks and increase the permanent clocks of the core and the memory. If you have been payin attention and reading the thread you would know this.

 

Be NICE...

 

thats what i like to hear steve...
i would like to point out that while im new here, this isnt the first forum ive ever been on, and in most cases i am on your side... and i understand where your frustration comes from. but i did read an article somewhere once upon a time from a questionable source that may or may not have mentioned afterburner so it stuck in my head... but you have cleared it up for me!

but my other relevant question remains. about mid way through the thread amal77 was talking about the clocks and mentioned that the auto scaling feature was broken... is this true. can i only run at 975mhz or the sleep clock of 135?

 

Hi there.

1) All the MOD shared in here is the normal voltage(including 975/1100 MOD), I haven't yet shared the OV, it need some more testing.

2) It will still have 4 clocks, Base clock(example 950MHz), 570MHz(usually if you don't force it to run at max performance, it will run at this clock), 180MHz(rarely see it running at this clock), and 135MHz (Idle mode). We are only missing on the boost clock, because it is currently locked by some configuration which I don't know.

3) We need GPU-Z and MSI AB to check and monitor our clock, to see whether we successfully MOD our GPU. If you want to keep monitoring your GPU clock, you may need to open both GPU-Z and MSI AB so that it won't stuck at the max clock OR you may may open 2 instance of GPU-Z.
As for overclocking, you can use MSI AB to OC your Memory, it still work, unlike the core clock.

 

thanks amal that answers my questions perfectly. thanks for all your work, its really amazing to see how great you make our laptops run!

 

Someone on Youtube brought up a good question on one of my videos. Can we update the Nvidia drivers once we have flashed the mod, without reverting to stock first?

 

that one i can answer. no you dont need to revert to stock, and you dont need to revert to stock to flash a new bios. however there is the inf mod roaming around that allows you to install nvidia drivers over sony drivers. and even after that it only needs to be done once. every new driver after that will just install.

and i know i looks like i have no life bc ive been every other post and that is partly true... but im beating my head against the wall as my vaio is supposed to ship any minute now...

 

Just curious if anyone is seeing any benefits running the latest NVidia drivers (not Sony one). I have read the S13 thread and a while back there were some comments that the Sony drivers seemed to work better than the latest/beta drivers.

 

Hi Amal,

Why is this "normal clock" - 570 mhz still higher than the the normal clock which would be 500mhz, right? Could you please also mention the memory clocks in the first post? Is the memory always clocked @ 1000mhz apart from the 975/1100 MOD? Does the memory also have dynamic clocks for different modes?

Again, thank you so much for the work and effort which you put into this project and which makes this machine so much more appealing!

 

I guess as what tmckenn2 mentioned.
It should be no problem.

Thanks for the explanation.

I'm not sure on this.
Been using 301.42 since the first day.

Updated on the first page on the memory info, thanks for reminding me(actually someone else already mentioned to me ).

I don't quite understand about your question on the 570MHz.
570MHz was supposed to be our Boost clock on default VBIOS.
I'm not sure why it is still in there. ^_^

 

thank you for the explanation and the update of the first post ;-)
I thought the standard clock was 500mhz (and not 570). I was wondering if a lower clock for standard mode would be good for battery life as we do have to switch to boost mode for games etc anyway. But maybe I just did not understand your post properly. English is not my native language btw

 

Still don't quite understand. heheh.

If your concern is on battery, then you don't have to worry much, because on idle the clock will stays at 135MHz which is quite low already.

You can also force the Laptop to use the Intel HD4000 by switching to the Stamina Mode if you wanna save more battery.

 

Thank you for this amazing BIOS tweak! I am currently waiting for my S13 to come in. In the meantime, do you think it would be prudent to install the newer nvidia drivers or stick with the stock sony ones? I know the VBIOS is what ultimately determines the clock speed, but would a change in driver have any effect on the card's ability to OC?

 

I'm not really sure though, maybe others can share their experience.

Though I'm using the 301.42 driver(not from sony) and it seems fine.

I have heard that different driver might affect the overclockability of the GPU. Again, I'm not sure.

There's a new dev driver(305.53) out there which I haven't tried yet.

 

Just became a new owner of the S15 ! I'm really interested in getting this mod to work flawlessly and not break anything. I'm not too knowledgeable on bios and system information so i was wondering about any details on the steps to do this.
first: do i need a certain version of the bios for this to work? like do i need to download anything, using whatever it came with atm (not sure how to check version number),
after that, is it a simple download, unzip and execute of what Amal77 posted on the first page?
is an overclocker program needed to get to the higher clock speeds? or is it an automatic thing if i set it to speed and set it to use nvidia card instead of the intel

any help would be much appreciated, just want to be careful and slowly know what i'm doing

 

Dude, seriously? Everything you asked is answered in the VERY FIRST POST: http://forum.notebookreview.com/sony/677079-sony-vaio-s-bios-mod-gt640m-le.html#post8706585

 

JukeX stop being lazy and start reading the first page of this thread!!

 

I'm currently using the beta verde driver 304.79. After applying the mod, my core clock stays at 935mhz even when not gaming. Not using gpu z, monitoring temps with msi afterburner. Also, where can I find official drivers? Nvidia site only lists beta ones.

 

Thank you for the info.

Please refer here for the 301.42 driver :
v301.42 Windows 7/Vista 64bit | NVIDIA Mobile OEM - 30x Series GeForce Driver release - LaptopVideo2Go Forums

So, anyone else face the same issue with 304.79 driver??

 

I used the 304.79 driver and i could not for the life of me get the gpu to clock down from 950mhz.
I had to send my laptop in for repairs so i haven't been able to figure out a workaround for dropping the clocks but when i get it back thats priority number 1
