SOB. I can't get ANYTHING windows related to boot up for some reason. Not Windows 7, not Windows 8, neither recovery options, nor the windows 7 cd. Across the board epic failure right now. The only thing I can get running is Ubuntu, which I had set up already (thank God). I'm wondering if it has to do with the BIOS, as it seems to be giving me similar BSOD errors. SVL7, could you possibly pm me on how I'd go about flashing back to an earlier BIOS version from Linux/Ubuntu? I would greatly appreciate it!

My y400 with windows 7 and a lower end SSD in the hard drive bay takes 12 seconds or less to get to the login screen. Used to be under 9 seconds when I first installed the OS, lol.

I wonder if its possible to control the fan speed now...

Actually, I did some more fiddling arounf with .bat files, and now I can get the voltage to go up to 1.2v, constant P0 state. It absolutely will not go any higher than that using .bat files. Maybe the slider will let you inch it up a bit more... I dunno. I can only get the overclocks to work correctly when I use either the .bat or the sliders in nvidia inspector. Touching both of them always causes problems, lol.

I flashed to the official 2.02 version using the easy flash tool included with the 2.02 file linked on the first page, then to 2.04 from that. And as far as blowing up the laptop is concerned, nvidia inspector and .bat files are a bit clunky to use, but it seems that there's a real cap on the voltage level in the slider, and in what the system will allow th gpu to run at. Setting it above 1.15 volts results in the gpu being knocked down to 1.15v when on full load, no matter what. I'd attempt to see if there's a way to get around that limit, but messing with inspector and .bat files too much seems to result in the core cluck going up without the voltage increasing, rapidly sending the gpu into "good night" mode . I can't use msi afterburner to change the voltage either.

You can now use software to overvolt the 650m using SVL7's v2.04 BIOS mod. From my testing so far using nvidiainspector to overvolt and overclock, the most it'll let me do is about 1250 Mhz core, at 1.15~1.187 volts max for the P0 state. However, it wont lock the gpu at P0 (boost state). Attempting to increase the voltage any more will usually see the gpu throttle down to 1.15 volts max, even if temperatures are below 85C. Even with those limitations, 1250 core @ 1.15v gives me a 3dmark11 score of 3440! Quite nice.

Oh wow, so software overvolting can be done with the 2.04 BIOS? I'll flash it right away . I can flash 2.04 from a modded 2.02 bios as long as I use the stock/official 2.02 backup to create the rom, right? Also, is this for 650m users? ***EDIT*** I can confirm that it works. Used the automated tool on the first page to flash the official bios version, then upgraded to 2.04 using the included mod tool. I can also confirm that you can use software to change the voltage! Awesome stuff svl7!

I also have Ubuntu installed alongside Windows 7 (primary) and windows 8 (never use it). Works great, just somewhat cumbersome to switch between them as Code mentioned. There's a way to have the ubuntu bootloader come up and give you the option of selecting between them without having go into Bios/boot menu, but I'm too lazy to attempt doing all that, lol.

^ I concur.

Just an update in case anybody was wondering: I switched back to the SVL7 2.02 bios, and still got BSOD errors when the gpu was overclocked with .bat files. I then updated to the new drivers, and the crashes seem to have stopped. Therefore, it was likely not a problem with the BIOS specifically, but the display drivers messing things up in the previous version. - - - Updated - - - I think what he means is disabling turbo boost will significantly cut down your temperatures. Same goes for using throttlestop to lock the core speeds above the regular 2.1Ghz nominal speed (to say... 2.4Ghz), it's still a lot cooer than letting the system boost up to 3.2Ghz. The loss in CPU power wont be noticed in any games, I'm fairly certain you wouldn't see a significant fps drop. OTOH, this would allow you to further overclock the gpu before reaching critical temperatures, thereby increasing your overall performance/framerates. You don't really lose anything by scaling down the CPU speeds, and gain more overclocking headroom for the gpu.

I'm just hoping they'll continue to carry the 650m version so I don't have to go about trying to flash 750m bios onto the internal 650m card .

I think I'm going to go back to the SVL7 unlocked BIOS without the voltage mod. For whatever reason, my system is very unstable (the BSOD on waking/shutting down problem) whenever I have the card overclocked, no matter how tame the clocks are (even at 1100 Mhz, stable on stock voltage). I'm assuming this has something to do with the card not liking operating at 1.1V, ot just something else in the BIOS...

Question... If I'm using a y400/500 with the 650m and bios v2.02, would I be able to upgrade to 2.03 or 2.04 (since I believe those include 750m BIOS, not 650m)?

After a few weeks of being too busy to play games, I can confirm that the use of nvidiainspector .bat files to overclock the gpu have been leading to the BSOD issues. Problem is it happens on clock/memory settings that were below even the point of stability on the other BIOS versions :/. I'm not sure why that is. Has anyone else had BSOD issues with the overvolted BIOS? Maybe my card just can't handle the voltage or something...

Thanks jester. Here's what it gives me from the latest BSOD. It's similar to the previous ones listed in the program. Also, these crashes tend to occur when I'm not at the computer, when the computer is entering sleep mode or shutting down: 053013-13821-01.dmp 5/30/2013 9:39:23 AM KMODE_EXCEPTION_NOT_HANDLED 0x0000001e 00000000`00000000 00000000`00000000 00000000`00000000 00000000`00000000 ntoskrnl.exe ntoskrnl.exe+75bd0 NT Kernel & System Microsoft® Windows® Operating System Microsoft Corporation 6.1.7601.18113 (win7sp1_gdr.130318-1533) x64 ntoskrnl.exe+75bd0 C:\Windows\Minidump\053013-13821-01.dmp 8 15 7601 295,088 ntoskrnl.exe ntoskrnl.exe+6d5fe fffff800`02e1f000 fffff800`03405000 0x005e6000 0x5147d9c6 3/18/2013 8:21:42 PM Microsoft® Windows® Operating System NT Kernel & System 6.1.7601.18113 (win7sp1_gdr.130318-1533) Microsoft Corporation C:\Windows\system32\ntoskrnl.exe hal.dll fffff800`03405000 fffff800`0344e000 0x00049000 0x4ce7c669 11/20/2010 6:00:25 AM kdcom.dll fffff800`00ba5000 fffff800`00baf000 0x0000a000 0x4d4d8061 2/5/2011 9:52:49 AM mcupdate_GenuineIntel.dll fffff880`00cb9000 fffff880`00d08000 0x0004f000 0x4ce7c737 11/20/2010 6:03:51 AM PSHED.dll fffff880`00d08000 fffff880`00d1c000 0x00014000 0x4a5be027 7/13/2009 6:32:23 PM Microsoft® Windows® Operating System Platform Specific Hardware Error Driver 6.1.7600.16385 (win7_rtm.090713-1255) Microsoft Corporation C:\Windows\system32\PSHED.dll

Is anyone else getting random BSOD errors with the overvolted BIOS? I'm getting them, and can't figure out a particular reason...

How do you go about disabling one or more cores? Is that only in the BIOS, or can it be done with throttlestop? It might be nice for battery saving.

I errored. Your first versions do scale down the voltage at lower clocks/p-states. I must've been drunk when I first examined it, lol. - - - Updated - - - Nice! The most stable one I can get with my single 650m about 1205 core, 2450 memory. For MLL I have everything turned up in the game settings, except AA is off and physx on, and that gets me between 30 and 60fps with the new drivers. The first time I tried to run the game it cooked my cpu, had it going up to 106 according to HW monitor :/. After that, I use throttlestop to turn off the turbo boost state while playing it. In fact, I'm doing it for all games, since gpu is still far more of a bottleneck than an i7 cpu. Running at 2.4Ghz for any game gives you power to spare, and keeps the temps around 85 or below even while playing Metro (vs. 95+ for most games with the GPU overvolt). GPU stays at 78~80 or below.

Wait, why doesn't it let you use software? Is it a locked version?

Make sure the filename is 8 characters or less.

I started playing that too. The new drivers do help, along with the latest patches. Initially the game nearly fried my system (temps went up to 106 on the cpu), and scared the heck out of me, lol. That game is definitely demanding, but the updates have brought that down some. Still, it grasps for every bit of GPU power, and as such, I've used throttlestop to disable turbo boost, which keeps my cpu temps in the 80s at all times.

I updated, and oc works just fine. Good boost for games too.

Is there no way to have the voltage scale up the way it does on the stock BIOS? I believe it should start low and go higher with higher core clocks. But on the modded one it stays constant.
