Lobby high = reboot

[M.Beier]

Hey, which part of the computer sets the limit if this test fails?? - None of the other causes reboot...

I can run everything else at speeds @ 327x8.5 - but only lobby high at 323x8,5...

Quite a difference...

I've tryed giving bad timings @ memory, didnt help :(

It's your memory failing.

Do you know your memory 1:1? 1t?

Running with divider, mem speed is just 0,xx mhz below 250mhz T1 2,5-2-2-5 (A64-Tweaker: 2,5-9-10-2-2-5-2-2-1-2 133Mhz 3,9us /// 16x 128 bit, disabled, disabled, 7x 9ns 6.0ns 256 clks enabled 166)

Could be mem voltage.

Tryed everything from 2.6v to 2.9v, no difference, tested mem with 32M SuperPI though ;)

Could it be because vcore is to high?? - Not running warm but... I got a REALLY bad PSU...

My 400W NorthQ with 15a ~ 12v has a hard time running my CPU + x850XT I guess...

By the way Oppainter... You've tested quite some x850 cards... - Stock VGPU is 1,4v, right? - Would I gain lots of mhz changing it to 1,65v with a vgpu mod...? - Running 588 for 24x7 usage - and benchable at 621mhz core (618 in 01SE).. And artifact free to 610 mhz core, but running 01SE+03+05 without rebooting causes computers' freezing :\

Maybe more mem volts, and try loosening that Trfc to 15.
