I can't get a backup of my bios made, can I use the one posted earlier in this thread if I have to send my laptop off one day?

Yes you can use the stock V2.02 I provided. That's what I flashed when I returned my first Y500 unit which was defective. That originally came with V1.05 but I flashed to modded 1.05, stock 2.02 and finally modded 2.02. When I returned it after getting a replacement I flashed both the BIOS and Ultrabay vBIOS using my backups and it worked perfectly to restore the factory firmware. If you need a backup of the stock Ultrabay vBIOS let me know.

I got excited and made no backup but I searched the web and finally found the original rom for the ultrabay gt650... and perhaps, if you have time and there's no big trouble I would still like that moded oc with whitelist v2.02 bios [without menus - I do development on this machine and if something gets wrong, the machine won't start [unable to reflash bios] and if warranty is required then they'll void it as soon as they check the bios - the chances they do a checksum or code comparision is less, but graphics is first seen]

svl7 said he's not going to release a version without the unlocked menus so just flash the stock BIOS back before taking it in for service if you're worried about voiding the warranty. Here is backup of stock V2.02 from my machine I made using fptw64.exe.

I did what you said,added admin in the compatibility section of fpt64 and then ran backup.bat, but it didn't make a bin file. The command prompt pops up for a second then closes so fast taht I can't read any of it.

If it generates an error file what does it say?

Sorry, I did make the flash drive, but to make a back up you have to run that in windows correct? I keep trying, but I get errors when I try and use backup.bat.

I can get fptw64 to run. It made two dll files are those the back up of my current bios?

fptw64.exe needs to checked to run as an administrator from its Properties>Compatibility. Then execute backup.bat and it will generate a BIOS backup as a .bin file in the same folder.

I'm new to overclocking and changing bios. How do you boot your SD card into DOS? Also, is there any point in your guide in which you need to load back into windows, and then back into dos?

You need to use a USB flash drive, not an SD card, and make it bootable per the instructions in the OP. Just follow the instructions carefully; everything is in there.

Thanks for the informative post. I'll have a go running BF3 with Throttlestop enabled and see what kind of temperatures I get.

Edit: Yeah, things got toasty quick. Most games seem to be GPU-bound on this system anyway, so it isn't too bothersome.

You never though. 2.4 GHz to 3.2 GHz is a big jump. A lot of games nowadays, especially the most recent shooters and RTS and MMO games will benefit from Turbo Boost even if you crank up the graphics settings.

If you don't need the unlocked menus... well then just leave them and don't change anything, it's actually pretty simple. It's not as if the additional stuff which shows up does any harm as long as you don't use it.

And as a corollary to this, don't mess around with any settings you're not 100% familiar with. Some of the settings, such as the ones related to the Intel GPU, don't do anything and some of them will disable important functionality or make your system unbootable. I messed around inside the modded V1.05 BIOS when I first flashed it and ended up somehow disabling one of my USB ports. I thought the port was dead until I flashed to V2.02 which reset all BIOS options and gave me back my USB port.

I've never seen temps over 82C on the CPU; with it being the 3230qm with a temp threshold of 95c before it starts throttling I know I still have some wiggle room, especially after I buy a laptop cooling pad.

That's a lot lower than what everyone else is getting. What is your maximum CPU temperature while running 3DMark 11, Prime95, and Linpack? Most people are getting around 90 C in 3DMark 11 when using ThrottleStop.

Unclewebb the ThrottleStop author has informed me that Lenovo, like most laptop manufacturers, has changed the thermal throttling scheme in this machine from Intel specifications. Intel sets the thermal throttling temperature for mobile Ivy Bridge CPU's at 105 C and the thermal shutdown temperature at around 130 C. They do this on purpose so that the CPU can gradually throttle without shutting down instantly, and it is almost always good enough to prevent the CPU from reaching anywhere near 130 C. That way the CPU slows down but keeps on running so that the user doesn't lose what they're working on. Lenovo, on the other hand, does away with Intel's incredible engineering and does a premature thermal shutdown at 105 C with no throttling beforehand except in the case I describe below.

By default, Turbo Boost will be disabled when the system detects simultaneous heavy load on the CPU and GPU, such as when running Prime95+FurMark or in certain portions of 3DMark 11. Therefore, the CPU will run at 2.4 GHz instead of 3.2 GHz. You can test this yourself by firing up a Prime95 torture test on all 8 threads. You'll see that when just Prime95 is running, each core will be running at 3.2 GHz,. But soon after you start up FurMark while Prime95 is still running, all cores will drop down to 2.4 GHz and stay there. This is similar to the CPU throttling mechanism triggered by the Bi-Directional Processor Hot (BD PROCHOT) signal but Lenovo is actually not using BD PROCHOT in this machine. This method reduces CPU heat considerably when both CPU and GPU are pegged but of course reduces performance.

What you have to do to overcome this is to use ThrottleStop and force the Turbo multiplier. When you do that, the CPU will run with Turbo Boost enabled under all circumstances. This is why people who are benching this machine recommend ThrotteStop to get the highest scores. In 3DMark 11, for example, the Physics score is around 6000-6600 without it and 7600 with it. The downside is obviously increased heat generation. In most real-world situations it's fine but if you do an extreme test like OCCT or FurMark+Prime95 the CPU will reach 105 within minutes and the system will shut down.

Hey svl7, definately sending you some booze money soon, really appreciate your fine work.

Any chance we can get a vmod on the GPUs? I'm up to 1175/1135 on mine with temps not exceeding 80c but they seem to be thirsty for more power in order to continue further. Thanks again for your work.

I believe the lack of thermal headroom, especially regarding the CPU, is holding us back. The CPU is already running near its limit and any increase in the temperature of the GPU directly affects the CPU since they share the same cooling system.

hey svl7, can you post the stock for the gt650m ultrabay ? and maybe a version of the rom with oc only for bios and ultrabay [without unlocked menu and without MODIFIED label - warranty won't like that]

That's what you made the BIOS backups for. If you need to get warranty service then flash back the stock versions. Anyway svl7 doesn't own this machine so he probably can't help you with the stock BIOS files. And I think it's a little too much to ask him to remove his watermark on the modded BIOS because then what's to prevent someone from taking his work, claiming it as his own, and soliciting payment for it?

Whoops, I need to fix that.

Hey svl7, how is the fix for default core clock reporting coming along?

I tried the Intel Rapid Storage before I modified my BIOs without any luck. If it is only limited by the BIOs, then would it work correctly now with the modded 2.02? Is it better than using Expresscache?

I think you're a little confused about what Rapid Storage Technology is. It is just another name for Intel's own AHCI/RAID controller drivers. It's required for RAID to work but not if you're using AHCI, although most AHCI users install it as well.

It is NOT used for SSD caching. That would be Intel Smart Response Technology for RAID-enabled chipsets or third-party caching software such as Condusive Technologies' ExpressCache for those who don't have RAID.

Has anyone disassembled the ultrabay 650m yet?

I have.

Repasting will not improve your temperatures. I repasted the Ultrabay GPU with OCZ Freeze, which in my experience works better than IC Diamond, and it didn't didn't help at all. Follow the advice of all of us who have repasted and don't do it.

Yeah bro i know it too ..that modded bios is better...if its not why would i flash...

I am asking to revert for a purpose...in future if suppose lenovo updated its bios to 2.03 or something else..slv7 also will update bios respectively ..in case should i revert back to stock and flash the modded bios again or can i update to modded bios directly. ..then a doubt raised in mind 'if i need to revert back then am i able to revert back to stock again or not' so asked...

If i dont have any backup can i flash stock bios directly?

And i had onemore doubt...am i able to overclock my single gpu...since there is guide to overclock only for sli(dual gpus)

Will u let me clear on that?

If Lenovo ever provides an official update then you would just do what we did for modded V2.02: Update to Lenovo's official BIOS then flash the modded version of that.

- - - Updated - - -

In Nvidia Control Panel go to MANAGE 3D SETTINGS

CUDA - GPUs: Change this to the second adapter, and now you will play games on the Ultra Bay Card

The best way to use this is of course to do this only with the program you need it for.

In my opinion you should put power scheme to balanced and do some nice registry editing and set the upthreshold higher, this is only for professionals of course. I wouldn't recommend touching it unless you know what you are doing.

That won't disable GPU0; all it does is force PhysX onto GPU1. As others have mentioned, since the display is connected to GPU0 it's probably impossible to disable it.

thank you bro... i successfully flashed modded bios...

thank you for helping me out

and i have a small doubt..can i revert to my original bios?

Glad to help.

If you saved a backup of your stock BIOS per svl7's instructions then you can flash that to go back to it. Make sure you turn on 'BIOS back flash' in the BIOS menu before you do. But I don't see why you would ever want to go back; the modded one is just so much better.

i tried to backup my bios by Fptw64 tool ..its getting closed soon after opening the bat file with admin permissions....

is there any way to make backup of bios?

plz help me out

You need to run fptw64.exe, not backup.bat, as an administrator. Right-click on fptw64.exe, click Properties, go to Compatibility tab, and check 'Run this program as an administrator' at the bottom. Then, run backup.bat normally and it should generate a BIOS backup in the same folder.

@octiceps - Do you think it's possible to disable the GPU0 and just use GPU1(ultrabay) as the main gpu? I think this will lower the CPU temps/

I do agree that this will lower the CPU temperature, but I don't think it's possible without some hacking, most likely not at all. If you disable SLI in the Nvidia Control Panel it just turns off the Ultrabay GPU.

The Intel Rapid Storage does not work on the Y500, as the Y500 does not support RAID setup from the BIOs.

In order to use the mSATA caching, you need to use Expresscache provided on the Lenovo site.

See here for instructions I used installing my 32gb Samsung mSATA

Y500 - How do I tell if automatic SSD cache is wor... - Lenovo Community

That's not entirely correct, Intel Rapid Storage Technology does work for the Y500, and pretty much all systems from the last few years. It simply installs the latest AHCI/RAID controller driver for your Intel chipset motherboard as well as a tray application that gives some general diagnostics for your connected drives. While it's obviously required for RAID functionality, most people who are using AHCI install it as well because it is the most up-to-date AHCI driver and should give you better performance than the generic Windows one.

Hello!

I'd like to install a small, inexpensive SSD as a cache for stock 1TB HD of my Y580. The problem is that I can't put together all the information in order to understand how to set it up.

Facts:

- HM76 supports RST (info via Intel ARK), but

- RST needs RAID mode activated in BIOS, which

- default Y580 doesn't have, but

- some versions of Y580 are sold with small SSDs for caching purposes.

Conclusion: caching is supported, but using strange configuration, such as software RAID.

Thoughts:

- If RST is supported by hardware, why Smart Response Technology isn't ?

- What is Lenovo RapidDrive ?

- What is ExpressCache ?

- If caching is configured in some stock Y580s, how it behaves in Linux or multiboot scenario? (if supported)

Can anyone provide a comprehensive guide ? It's would be nice to clarify this questions once and for all...

Thank you very much !

That is true. HM76 does not support RAID or Intel Smart Response Technology, only HM77 does.

I don't know what the situation is like for the Y580, but for the Y500 configurations that come with the 16GB SSD cache, they bundle third-party caching software with the machine. I believe that for the Y500 the included SSD is a SanDisk one, so the bundled software is a SanDisk-licensed version of Condusive Technologies' ExpressCache software.

hm...i can´t get my second GPU to flash I followed the steps in the guide and already flashed my bios to mod 2.02V which worked fine, the nvflash part tells it´s working but doesnt do anything

removed write protection with

nvflash -i1 -r (says write protection is removed) then flashing with nvflash -i1 -6 sli.rom which also runs through and says bla successfull complete but nvidia inspector doest show bios as modified and clock is still locked any suggestions ? nvflash -i 1 -r || nvflash -i 1 - 6 sli.rom has same effect, no errors warnings or anything displayed

as I was flashing the bios I found 2 things misleading in the guide

Put the fixed BIOS, the prr.exe tool and the fpt.exe (along with the fparts.txt file) on the root of your prepared DOS bootable USB drive, restart your system and boot from that drive.

It sounded to me like I was going to flash the v202Fix because the downloaded v202.rom was not mentioned

fpt.exe -f filename.bin -bios

made me wonder if I had the right file because of the .bin extension in the example and the downloaded .rom

note: your win8 will not boot into desktop the first time after flashing, win8 will restart once and show screen like first boot (little tutorial thingy, don´t panic you didn´t format ^^)

you may change that for others who are not venturous enought to just try it

I don't know, svl7's instructions seemed pretty straightforward to me. I got everything right the first time around and didn't run into any problems.

You can confirm that your BIOS flash was successful by booting into BIOS and it should say 'svl7 mod' at the top-right corner with a bunch of previously-hidden advanced options unlocked. Also, Nvidia Inspector should show the vBIOS of GPU0 as '80.07.27.00.33 [MODIFIED].'

If you have SLI and successfully flashed the vBIOS of the Ultrabay GPU the Nvidia Inspector should report the vBIOS of GPU1 to also be '80.07.27.00.33 [MODIFIED].'

If everything completed successfully with no error messages but your BIOS is still unmodded then the only thing I can think of is that you got the files mixed up and didn't flash the correct files. Double-check everything and flash again.

Oh lord, I got it now.

I don't understand how I missed it. It's morning now, perhaps late night tired induced witlessness? 1080p screen makes things too small? I didn't have my glasses on?

*cough*

Took you long enough LOL.

Whoops, I need to fix that.

Thanks. It's merely a reporting error but should ease a lot of paranoia from users who get confused.

Any success, OP?

It's already been available for a few days. Check the sticky at the top of this subforum.

Nope, I got that. I'm talking about turning the write protection off using the -r command. Otherwise it gives you a write error when you try to flash?

Gee you are blind.

nvflash -iX -r is the command to remove write protection. That's what I lassoed in that screen capture. Far-sighted much?

Erp, seriously? I read it all twice, and the nvFlash guide. Eeeeeerrrr, whoops.

EDIT:

Honestly, I can't find see it? Am I that blind?

Yes you are.

Perhaps it'd be good to include a note about turning protection off for flashing the SLI card? It was a stumbling block until I remembered someone mentioning it.

Actually if you read carefully he did write that in the guide.

I see u use 306 driver, 310.9 or older driver u don't need modding the bios!

LOL I know that; I've been keeping up-to-date with all the developments and am well aware of these things.

Of course I'm going to update to the latest driver. 306.00 doesn't even have SLI profiles for games released in the last 6 months LOL. I just haven't had time to do a clean install yet, so as of right now I'm still rocking all the factory drivers and bloatware.
