Prime 95 shuts off computer no BSOD.**Fixed***

post #1 of 21
Thread Starter 
I thought it might be voltage but now I'm not sure. Just installed XSPC Rasa and went up to 4.2 after being stable @ 4.0 for months.

I've been playing with voltages for a bit with no luck. This all started happening while at 4.2 Ghz. All I upped multiplier to 21 from 20 (at 200 FSB) and while playing GTA the computer just turned off completely. No BSOD and I already have windows set to not restart on BSOD.

I doubt it's this, but did you check temperature?

Temps are fine. XSPC Rasa is a beast. Computer is booting just fine, for some reason as soon as a big load is put on the cpu it shuts off and reboots. I wonder if my mobo isn't seeing a cpu fan and shutting down to prevent damage...

just a stab in the dark, could be the psu providing dodgy voltage.

I was oc'ing my 480's to 850 on the cores while oc'd to 4.2. Think I could've bunt my PSU or damaged it?

I doubt it, Ultra isnt a top end PSU, but its not all that bad. I have run a few of them.

For your system you dont need much more than 850W so I doubt you could have overloaded the PSU.

How old is it? If its old it may be starting to give out..

Try a different setting, maybe go for 210 and the 20 multi.

Some CPU's dont like certain multi's...

What are your voltages?

WHOA!!!

Just saw the SS, why do you have your VTT at +850? That is crazy....

You dont need more than 150 - 250...... +250 = about 1.35v which is Intel's Absolute Maximum

this is my 24/7 voltages for 185 x 23 - 4.25
Code:
Voltage Control
EVGA VDroop Control ( Without VDroop )
CPU VCore ( 1.35 ) 
CPU VTT Voltage ( +150 ) - 1.33v windows
CPU PLL VCore ( 1.80v )
DIMM Voltage ( 1.65v )
DIMM DQ Vref ( +0 )
QPI PLL VCore ( 1.20v )
IOH VCore ( 1.25 )
IOH/ICH I/O Voltage ( 1.575 )
ICH VCore ( 1.2v )

Yeah...that was a dumb run. I have it at +100mv now. That's where it was to begin with when this all started. I'll try upping the multiplier.


Edit: Tried multiplier and nothing. Trying to tighten up ram timings. Been up for hours now. Think I should give up and try when I get up later.

Wow...this is really getting annoying. No BSOD, just the computer shuts down at full load.

Tried GTA, Vantage, Prime, it seems it only does it at full load.

Need some sage advice here. I'm seriously considering going out right now and buying a 950 and just saying screw it. I think intel will still rma and it would make for a nice spare chip.

Opinions? Should I just get a new chip and be done with it?

picture of your rig? i think its your PSU also cause the only time my pc shut off is when my psu over heated because my fan is facing down with very small air flow.
