My Corsair 2x1GB passed memtest for 8 hrs on Expert while that setting could never go for more than a second with any benchmark. SuperPi errored out as soon as it started. Windows had frozen screen. I spent hours only to find out, it's the DRAM Drive Strength issue. On my Ultra-D it's ok at Level 7 so I just copied that value to my Expert. Turned out, it has to be Level 9 to be stable with the Expert.Quote:

So have fun tweaking some more!
I actually don't know what Merlin BIOS is based upon.. AFAIK, folks at DFI-street are very happy with it. My Expert had trouble with official 406 BIOS (can't push FSB > 300MHz) but once I flashed it to Merlin 10-07-2006, the FSB could finally go as high as my Ultra-D (~355MHz.) TMod's v9.0 CD has a more recent Merlin BIOS release. Give it a try if you have exhausted all the options. Hope this helps.
Ok thanks guys, I knew memtest wasn't 100% but but I never had a situation where it wasn't. I'll check out this merlin BIOS. Does anyone know though why with the 3.3V jumper Mod though I don't have more than 3.2V available? For some reason I think I recall that your not supposed to flash your BIOS with the jumper mod...can anyone confirm?

Damn, that was it, I forgot about the CPU Voltage thing!

If the pc only froze or the superPI, ORTHOS just reported error but keep the pc running, it is fine and I know that prob either ram or cpu problem.
But it wasnt, many of the time it just power off by itself which is scary me.:slapass:
Hopefully it was just casued by the ram, not the damage of the mobo
dual priming @ 3003MHz at the moment .
Opty 175 CCBEE @ 1.4V

will post pics in a few hours if this thing stays stable...
DevilCry, how'd it do? Any further testing? Stable?Quote:

You probably got software issues then, or do the problems dissapear on lower speeds? How's prime?Quote:

won't hurt to tryQuote:

It's CCBWE 0550 UPMW. And I have it under a Coolit Freezone. Dual-priming at ~2.7@1.56v gives me Core Temp readings of ~50C. I was under the impression that the AMD processor drivers were only useful if you planned to use Cool n Quiet.Quote:

It's not a problem as long as your temps are OK. 50C is fine for that voltage. I'm actually selling my 175 and grabbing a 165. Of course I'm going to ascertain the stepping first, this time around. Hell, half the fun is just overclocking these suckers. Then I'll worry about my gaming addiction.Quote:

i'm working on a stable setup right now so that i can be a member of the 3GHz club :D
Good luck brother. :)Quote:

I've now ordered a NEC pci usb2.0 controller and will disable the onboard one.
Thought it may be of help to somebody.

Definately software related then, start removing drivers one by one until the application that crashes for you stops behaving that way.Quote:

Can u help me with it?

Thanks :rolleyes:
My lock ups would be totally random. I have a few things connected to usb, ipod, printer all in one, Ps2 controllers, hub, mobilephone cable, digital tv receiver etc. I'd be surfing or in Word. More frequently, we'll be playing a game and it would freeze (the ps2 controllers).Quote:

Hopefully the new USB pci controller will work without conflict.
lol got my Opty 165 0617fpmw some cold this day.. its coldbuged bad, when temp its around +6c-+10c its look with htt over 350mhz :( , i will test the Opty 170 later.. i think it will be much easyer... 10 multi x 350htt =3.5ghz
0615 EMPW @ 3.06 @ 1.525 vCore on Water with my old 2x 512 Kingston Value RAM... I dont know why, but I cannot make it work with my GEIL 2 GB Kit, maybe some of you guys could help me:
