It's the same bios for Lenovo Lenovo Y400 and Y500. I think the difference is the size of the patalla. Thank youGil Quote Link to comment Share on other sites More sharing options...

Ullebulle Posted August 18, 2014 Share Posted August 18, 2014 Can you run 3DMark 11?You flashed your 650M Ultrabay vBIOS with the modded 80.07.27.00.33 in the OP? Does SLI work for you in Window 8.1? I thought it doesn't?I use win 8.1 and yes the sli works very well. At first when i upgraded, i had to update my ultrabay gpus vbios with upgrade by lenovo. But at the moment i use the 2.04 bios from the first pages attachments and the ultrabay modded bios from the attachments also. Works perfectly. It will allow you to increase voltage, clocks over the +135 limit but so far only with nvidia inspector. Quote Link to comment Share on other sites More sharing options...

Correct me if I'm wrong.First you flashed factory 80.07.27.00.33 vBIOS to .3A from the official Lenovo update. Then you flashed modded 2.04 sBIOS. And .3A to modded .33 on the Ultrabay. Now you have unlocked overclocking limit and voltage control and SLI still works in 8.1. Is this right?Can you provide screenshots of your Nvidia Inspector for both cards with overclocking window open? Thanks. Quote Link to comment Share on other sites More sharing options...

octiceps Posted August 18, 2014 Share Posted August 18, 2014 Interesting...So I wonder why my modded .33 vBIOS on the Ultrabay does not work for SLI in 8.1. Perhaps flashing it over .3A overwrites something and fixes it. Are you able to update Nvidia drivers without breaking anything?One last thing. I noticed that you have prioritize temperature checked and set to 91C on both cards. Are you able to remove this temperature limit? Because every time I uncheck it, it automatically rechecks itself. Don't know if this is a driver or Inspector bug. Quote Link to comment Share on other sites More sharing options...

Don't know if this is a driver or Inspector bug. Haven't really updated any drivers yet. Have the latest drivers as you can see. And i could not uncheck that either, although haven't been that close to 91c 87 during 30min benchmarking. During gaming like bf4 top 82c. i really hope that everything stays in its place when updating drivers. I'm really not the right person to help you here, i'm just an novice with these things, but i will do everything in my power to help you, which ain't much... :S Anyways, here is the order i did things. Win 8 SLI works fine. --> win 8.1 SLI stops working but the problem was fixed with second vga update. ---> decided to overclock with the bios mods, flashed to 2.04 found in the attachments of the OP, nothing changed in the nvidia inspector after this one. ---> flashed the index 1(ultrabay gpu) with the vbios mod provided in the ops attachments. Nvidia inspector was now unlocked, boost disabled and the OCing began. Hope this helps at all. I suggest you follow the instructions perfectly, dont miss anything like i almost forgot to disable write protect from vbios with nvflash -i1 -r command . I wish you the best of luck. I answer here as fast as possible if i can provide you any help, because i'm living proof that even a person who doesn't understand these things better than a pigeon understands quantum physics, can do this by following instructions. (not that pigeons could help us with quantum physics even with instructions but anyways). Sorry for the bad joke. I'm a bit tired right now so it was funny to me... sorry for the bad English also. You can pm me also if it does any help. Edit: corrected some words. 1 Quote Link to comment Share on other sites More sharing options...

Jeka-22 Posted August 19, 2014 Share Posted August 19, 2014 This will work if SLI was enabled by flashing . Try SLI disable and re-enable, you will get an error 43. Sorry for english Quote Link to comment Share on other sites More sharing options...

Sorry for englishSo basically you're screwed if you update your driver since it disables SLI automatically. Quote Link to comment Share on other sites More sharing options...
salmantkhan Posted August 20, 2014 Share Posted August 20, 2014 How to check your current bios version, as I have ordered an AC card and it turns out I found out about this issue and would like to resolve it before receiving the card.

And no I'm not going to try that. Can't understand why would it stop working after disabling sli and trying to turn it on. Everything works perfectly otherwise so far.

2dotcom Posted August 22, 2014 Share Posted August 22, 2014 hi there! new member here. got here because i was trying to upgrade my wifi card and found out it's not possible without the bios mod from svl7. damn you lenovo!! Quote Link to comment Share on other sites More sharing options...
programmargorp Posted August 23, 2014 Share Posted August 23, 2014 TECHNICALLY what you can do is1) Flash the Lenovo SLI BIOS for W8.12) Enable SLI3) Flash the Modded BIOS.SLI will still be enabled and you'll have voltage control. The problem would be that if you disabled SLI for any reason, you'll have to do the above steps again. Quote Link to comment Share on other sites More sharing options...

DARKWORLD Posted August 23, 2014 Share Posted August 23, 2014 Nah I upgraded to Windows 7. I said "fuck it" and did the same two weeks ago. Tried to solve somehow, but when I learned about VSYNC bug I was 100% positive to move back on 7. Quote Link to comment Share on other sites More sharing options...
NyMartin Posted August 23, 2014 Share Posted August 23, 2014 I did this whitelist BIOS mod back in January. I updated to the modded bios and put in a new WLAN card in my Y500.My issue now is that I have a 1TB HDD and the 16GB Cache Msata in my y500. I just bought a 1 TB Samsung mSata to make it the boot device, however whenever I try to boot the system without the 16GB cache device (in legacy mode since I put Win 7 on my Y500) it gives me an error that says Atheros and that there is no bootable drive available. This is impossible since my 1 TB HDD Win 7 is my bootable drive. Any help on why I can't boot to my Win 7 HDD to then migrate to my new 1 TB mSata? It's very frustrating since I bought the mSata and now I can't make it my bootable drive/ migrate OS to it. I've also tried using a bootable Win7 USB to just try a clean install on my new mSata but it hangs at the Lenovo logo screen at boot not going anywhere when the Win7 USB is in. The system boots fine when my 1 TB HDD is in and the 16GB cache is in, which makes no sense to me that the cache needs to be in.I'd really appreciate it if anyone can help me with this as soon as possible. Thanks TechInferno. Quote Link to comment Share on other sites More sharing options...

I'm officially done with Windows 8 forever. I can understand why M$ is abandoning this POS. Full steam ahead for Windows 9. Hopefully it's any good, but I'm not counting on it.
