Sony Vaio S Bios Mod For Gt640m Le

Wow...thank you very much @kanuk!!!
...it´s so easy...hehe great work and great forum...tschüßi

 

Hi guys,
One stupid question.....I have a S15 that came with Win8...Can anyone suggest how can I change the BIOS to overclock the gfx card?

 

You can't. Please read the previous 100 pages of this thread.

 

Short of a physical replacement. Could be fun

 

Ok it is now April, Did SVL7 or Amal finally find a way to bios mod the Windows 8 version of S13/S15?

 

SVS13A15GG : S Series : VAIO™ Laptop & Computer : Sony India

This is a Windows 7 version with the 2GB 640LE - will the BIOS mods work here? Thanks!

 

It should.

 

Hy,
I`ve searched the thread and almost found my answer, but still feel beter to ask. So the new Nvidia driver boosts up the performance for Tomb Raider and Bioshock i really would like to use this driver, but as everyone know if i update my clock and memory speed drops. Is there a way to update? with this changing ini files or what? maybe? if yes, how exactly?

 

If i have a windows 7 machine, and update it to windows 8, will the mod still work? and does the process change?

 

Yes it still works, no the process doesn't change. You will have to reinstall the BIOS after you upgrade to W8.

 

Just did the Mod to my 151S. 3d Marked 2145 at 935/1000. I was only temping at about 63-64C . Going to try 1000/1000 now. I am using the latest driver that still allows overclocking. 310.90 driver. Is there a better driver for performance or is everyone using that?

 

Temps mean absolutely zero in this scenario, just use the highest speed bios that doesn't give you artifacts in any game

 

Yes I understand that. I was referring to the Nvidia Driver. Im using the last one that allowed for overclocking. Is there an older one that might give better performance that I can test it against? Anyone using another one besides 310.90

Thanks

 

Well, the newer the driver, the better the performance. As 310.xx is the latest driver which allows overclocking, I'd suggest you to stick with it, until someone comes out with a workaround.

 

Temps will depend on the game. I get ~60C with some games and 75C+ on others.
If you mod too high it'll simply crash or you will see weird colours and artifacts - it won't let you fry your card.

 

hi, is it possible to build a bios with 1000mhz on core and 1150mhz on memories...maybe could it be stable

thanks!

 

The memory clocks are software overclockable. You can go ahead and try it in software.

Anyone owned the latest Vaio SVS13A390X?

Saw there's a new BIOS(R1021C8) on this model.
Sony eSupport - SVS13A390X - Drivers & Software

Not sure if this one is locked or unlocked.

Anyone willing to give a try?

Edit : Those like the SVS1313/SVS1513 with a BIOS R1020C8, MIGHT also flash this BIOS, knowing how Sony BIOS works previously.

 

I do have the bios R1020C8. Is that locked or unlocked?

 

I can update my fall 2012 model to that BIOS. I currently have R0081C8 bios. I searched for it in the tread, but no matches How can I try the mod? Is there a serious chance I will brick my laptop? Rather not, just one day old..

 

No you can not at the moment.

 

Hi guys!

I´m using notepal u2 when playing. I´ve got decreased around 4 aprox. celcius degrees in highest temperature, and 5-6 in average temperature.

The problem is: When idle without notepal, I think that fan noise has increased a bit. I measured it with an iPhone App just on the right side, where it has the air supplies and it marked 48 dB.

Is this a good value? Or am i going nuts?

Thanks in advance!

 

is there also a version, where the advanced options are enabled too, like here:
http://forum.notebookreview.com/sony/641671-sony-vaio-sa-sb-sc-se-advanced-menu-bios-hack.html ?
or maybe someone could combine them?

 

That bios mod is for an old vaio, Don;t think they will be combinable, but I don't know much about it so I could be wrong.
Currently there is no advanced bios mod hack that i know of.

 

Interesting thread ... anyway, i have SVS1513C5E EU model with BIOS R1021C8.. can i flash the nvidia bios too? thank you.

 

Read the first page or the last 5 pages then you will know

 

i did, few times but didnt find proper answer... nevermind, thank you for help...

 

This may be a silly question, but I have a Sony Vaio S with windows 8. If I was able to switch the operating system to windows 7 would I be able to use the BIOS mod?

 

I want to know this too. Or does one need to modify more than the operating system to make the gpu mod work?

 

no, The bios is independent of the operating system.

 

I understand.
Other than the screen, this fact is the only thing holding me back from pulling the trigger on this amazing notebook

 

you can pretty readily find windows 7 versions new on Amazon still! Just pick up one up there and your good to go.

 

Just got one, in Used - Like New condition for 670USD. Great deal.

 

Wow! that was with the 640m Le right? There is also a non premium s13 that does not have the dgpu

 

Yep, i5-3210, 640GB HDD, 6GB RAM, GT640M-LE, Windows 7 Pro,1600*900 screen. BIOS modding, here I come!

 

Hi guys.

I have the SVS1511V9EB with the GT640M le but this bios mod doesn't seem to work. GPUz detects the 1000 Mhz but when I run 3DMark 2011 I get the results from 500Mhz. I double checked the settings on the NVidia Control Panel but still get the same results. I flashed with the new bio mods R0143C5.

The results were the following:





help would be good

 

What driver are you using?
Anything after 310.90(I think) doesn't allow the overclock on our cards.

Try that.

 

Yes, the 310.90 is the last one we can use. Is there a fix for the newer drivers?

U use the 314.22 driver,take the old one and then everything will work.

 

Anybody know where I can find the BIOS/EFI flash IC on my SVS1312H3ES motherboard? I want to flash a new IC (pin compatible) via flashrom and change it with the original to overclock


@Amal77
Can you say the tool name for mod the Insyde BIOS? I want to mod my bios (R0081C8), because I dont know if I could use the older modified bios file.

 

Can I software overclock the gpu after installing the bios mod? Nothing seems to work.

I have a like new, boxed and BIOS - moddable S13 Premium available if anyone is interested? Comes with sheet battery and Premium Sony leather case. Just mail me slvrarrow(a)gmail(dt)com, I'm UK based.

 

so I modded the bios successfully and then undid it using the stock bios via the first page as instructed because i thought i was sending the unit back. Turns out I am keeping it, and now I can not get the mods to take. I run them, it appears sucessfull, but when I run a benchmark it still scored around the same as the default bios.
Any suggestions?

the system is a SVS13A12FXB , windows 7 model. I succesfully installed the 1000/1000 insyde mod earlier. Now I have attempted multiple and none of them take.

 

Which driver do you use? It should be 310.90, not newer.

 

Hi guys, I've few documents/pictures and infos for the new SVS1312 Win8 model:

Here is the Service Manual for SVS131 from 2013:

2012
http://www.docs.sony.com/release/MDSM/989092601_sm.pdf


And few pictures from my disassembled SVS1312H3ES Windows 8 Model. Images may be helpful for anyone

Images.rar (high res images)




I disassembled my netbook (you can see it on the pics) to desolder my BIOS flash IC (on the last image right under the battery). It's a Macronix "MX25L6406 EM2I-12G" 8pin SOIC. @ the Bios menu screen (or with CPU-Z) it says its a MX25L6405, the old and discontinued version from MX, because the new chip have the same SPI ID! After desoldering, I've read the content (64Mbit = 8MByte) with the tool flashrom.exe (Win32 v0.9.6.1 - r1671 specially compiled for me and my chip ). I've sent the backup to svl7 to unlock the OC function for me.

 

Cool, I hope svl7 can work his magic. I'm contemplating the Vaio S, but am being held back by the difiiculty to overclock at the moment (with the newest models).

How far can you overclock with a stock Windows 8 version, using Nvidia Inspector (and possibly the older driver)? Anyone has some info on that?

Good luck ottelo! I see btw that your mainboard does not have a TPM module (page 3-4 of service manual). Which versions do come with one? Or can we buy it separately?

 

There's info that 2013 models preinstalled with Windows 8 are not supported, but what about 2012 models? Can I use modded BIOS under Windows 8?

 

that's great man! hope for unlocked bios, thanks ottelo and svl7 =)

 

If it came with W8 from the factory, the BIOS mod will NOT work.

 

And if it came with W7 Professional and I would like to try Windows 8 and get BIOS mod working in it? Then what?

 

Then it will work. Mine came with W7 and I upgraded it to W8. You just have to reinstall the BIOS after installing W8. I use the 900/1000 mod and it works fine.
