A tad dissapointed

[shils]

Hello to all! Been lurking and reading this thread for a few weeks now and decided to pop in for a little advice. I Just finished building my new A8N-SLI rig a few days ago. It's guts are as follows:

A8N-SLI
Athlon 64 3000+ winchester
2 512 OCZ platinum rev 2
2 XFX 6600 gt's
Ultra X connect 500 watt P.S.
W.D. 74 gig raptor SATA
Maxtor 300 gig SATA
NEC 3500 DVD/RW
Thermaltake Big Water cooling

The thing went together perfectly, XP pro installed without a hiccup, Nforce, video, and sound drivers went in without a hitch. And she runs along pretty snappily. (no benchmarks, sorry)

Thing is, when I attempt to overclock, even a bit, I get the "boot fail due to overclock" message. I can get maybe up to a 210 FSB, but anything over that and she'll choke. I've had the voltage tweaked up to 1.5 and I'll be able to boot once right after exiting bios, but on a system restart.... "boot fail due to overclock".

She's running really cool, (I live in Alaska and the box is located next to a sliding door that leads to my porch which remains open a crack so my wife's plants don't croak). Speedfan reports CPU @ 22C at idle, 28 under load. (nice now, but it'll go up in summer I'm sure.) Anybody got any ideas? Did I just get a weenie chip?

Prolly or maybe something just ins't right with the mobo.

Have you tried 3dmark? I think you should 8)!

Im pretttty sure that its the mobo, the least ive seen people able to OC their winnies is like 2.3ghz.

Make sure you have the PCI bus locked, set your HTT multiplier to x4, and try raising your memory timings to something like 2.5-3-3-10.

Adrian's Rojak Pot has a nice BIOS guide that may help.

Since it's such a new board, it's hard to say what else it might be. Maybe some of the SATA ports aren't locked, a la the MSI Neo2.

my guess would be your memory can't handle it at the timings you have it at, though OCZ is good for getting obcene FSB speed its timings are sloppy as hell. Personally i recomend Crucial Balistics or Corsair Xtreme for an AMD system the OCZ does better in Intel because intel needs the bus and the sloppy timings does not effect it as the processor is not as tight as the AMD

I agree make sure your HTT is 4 or 3 you can find this in Advanced under CPU configuration. I recomend setting the memory timings to "Auto", then increase your CPU voltage to 1.5-1.55 in the jumper free settings.

Your ram is not a problem. I have the same ram(OCZ is the best ram ever! Crucial phooee!) and I have had the FSB up to 290.6(the max for this board). I am currently running 270 x 9.5 = 2565mhz on a Winchester 3200+

Beside, when you raise the FSB past 220 the board will automatically apply a memory divider and run your ram asynch between 160-190mhz @ 2-2-2-5 timings.

To run you memory 1:1, you have to set the memory clock manually to DDR400, DDR433, DDR466, or DDR500 and adjust FSB from there. I can run 246 x 10 = 2460mhz w/ram 246mhz @ 2.5-3-3-8
