well i updated my rig and i still have my 550w BFG psu and i can't get my rig to a stable over clock. my rig is

intel Q6600
asus P5N-E SLi mother board
2gb ozc platinum PC2 8500 1066mhz ram
2 XFX 9600gt xxx alpha dog in SLi
550W BFG psu

when i oc my rig it will be ok until i start putting a load on it and it just reboots.
I'm thinking sence the vid card boxes state that for sli i need a 600w power supply That maybe my problem i hope.
any ideals if i need a bigger psu.

It reboots? Then I'm not sure that's a power supply problem. Sure, sometimes if a PSU's voltages drop out of spec the PC can reboot, but there are a lot of other things that can cause this that aren't PSU related. More typical PSU problems would be shut down or lock ups.

How did you "update" your rig? Buy adding one card? Adding both cards? In other words: At what point was it stable and then what did you change when the problems began?

Go to System Properties, Advanced and click on Settings for Startup and Recovery. Make sure the box is unchecked for "Automatically Restart". There could actually be a BSOD that you're not seeing.

That said, you ARE pushing a 550W PSU with a pair of 9600 cards, but let's make sure we nail the problem before swapping out a bunch of parts.

i updated by going from a AMD 4800+ skt 939 to a intel Q6600 and from a 7800gs AGP card to the 2 9600gt's and from pata HDD to a 500GB sata HDD

Ok...

So you swapped out the motherboard, CPU, graphics card, hard drives... RAM too, right? Didn't you go from DDR to DDR2?

So this problem really could be anything.

Start with disabling the "automatic restart". Did you do that all ready? What happened? Did you get a BSOD this time?

[DieHard007]

yes i did that and haven;t oc yet every thing is fine stock

what is the vCore? not enough perhaps?

[DieHard007]

one thing that really puzzles me is i can change the vcore voltage in bios to any thing and it still reports on cpu-z as 1.262v all the time. and the north bridge heat sink is so damn hot you can;t even touch it. at any voltage form 1.2 to 1.5 volt.

My Asus board is the same way. Pissed me off.

So go ahead and do the OC, run Prime95 and ATI Tool and see if you get a BSOD.
