Hello guys.
I just unlocked the voltage tweak , it seems I can set more than 1087 MV but when I try to set for example 1150 , It doesnt apply.
My MSI version is 2.1.0. Do I have to flash my 465 GPU ? If so , how ? Thanks.

Also what is the absolute safe voltages ? How far can I go on my ASUS GTX465 ? Im currently at 800 / 1600 / 1900 @ 1087 but you know ?...

I have a GTX 465 that unlocked to a 470. I have run the volts up to 1.215v on a few suicide runs (950 / 1900 / 1900 clocks) with the original cooler @ 100% fan. It would be stable with that setup IF I had water cooling, Im not comfortable with 95c temps in furmark. Temps usually were around 80c in games at those settings, but for safety I dropped back down to 800 / 1600 / 1800 @ 1.087v.

In reality, for my setup the conservative settings are better. I can run almost everything with 8-32x FSAA and max details, but I am resolution limited at 1680x1050.

For your problem, a modified vga bios is REQUIRED for more than 1.087v. You didn't mention anything about flashing it, so I'm going to point my finger at the NV voltage limitation in the BIOS.

Oh, forgot to mention... As far as I know, ~1.2v is a hard limit on the cards. The voltage regulation circuit probably can't even supply that voltage reliably with 100% load.

Haven't had any luck with editing on these forums yet, sorry for the double post.

Thanks dude , yeah I flashed my card and I can set high voltages now.
Its still 465 though.
My overclock is 800 / 1600 / 2000 MHZ @ 1112 v.
Fans are maxing at %80 and max voltage is 79 C at BF3.

Just be careful not to burn your card like frenchdonuts did here at OCN

Thanks dude I'll take a look to that thread.
