Why you wish I get a bad board

was jk man

Not really. I cannot run my memory at its standard 1600MHz at any timings.

damn :/
are you sure its not the mem tho?
does it work fine on another board or 50mhz lower or higher than 1600?

You're also running 24 TRAS man. I'm running 20.
That's huge.

dude, tras doesnt really have an impact at all...

I got my evga board back from step-up today. I took 4 weeks, so while I have been waiting I have seen all this bad stuff happeing. So I hoped mine would be OK. But with an E8400, 2x8800GT and Kingston 1600 7-7-7-20 2GB it's not stable at stock. It crashes in CoD4 after 2 mins. I have tried a lot of gtlf volts, and vtt's. But 10 mins of CoD 4 is the most i can get out of this board. And that was with Vtt 1.35 and -0.25mv. Lowering the ram to 1333 doesn't do diddily, nor do any vcore. I will continue to try combinations of volts, but I was looking forward to play some games after 4 weeks without a computer. Is there any hope P03R2 is better than P04?

wow... kingston bins very lose... so the mem should def be fine...
not even 1600 or 1333? i mean lets say its a config problem, and if configured rght you can get the board stable... but thats not ok... how many hours is it supposed to take tweaking to get the system stable at stock? :S

and you disabled p1 and p2, right?

Ok, here are my settings for 445FSB prime stable for 14 hours with no errors on any cores.

QDR/RAM=1780 Unlinked
PCIE1/PCIE2 = 100
SPP<-> MCP= Auto
vCORE=1.375(1.344 in windows per cpuz)
Loadline =Enabled
vTT = 1.28
PLL=Auto
vDIMM=1.9
vSPP =1.46
vMCP = 1.55
CPU GTL_REF0 = -29mV
CPU GTL_REF1=-32mV


I am gonna run 3dmark06 in a loop, to see how 3D stable I am.

sweet, finally some good news

thanks for sharing!

I don't know why disbling SLI would crap the driver out.

either your not 100% stable or... the nvidia driver just crapped outlike they tend to do
dont forget the statistics microsoft released showing one 3rd of all reported vista crashes were caused by buggy nvidia drivers

im going to update the first post of the 790 corruption thread now
