Overclocking Problem on a A64 3200 Venice

[killdroidxx]

Hello I realize this OC may be a little after the fact and it might be a better idea just to upgrade to a new system but I'm broke I have an Athlon64 3200+ Venice on a Abit KN8 mobo. I have some pretty crappy memory mixed w/ some halfway decent stuff. I have 512 of DDR400 and 2x 256 DDR266. I have a brand new Antect 500W PS.

The problem I hit is when I try to OC the FSB even a little bit. I can get it to run at 210 when I send the HT down to 4x. But higher than that and I can't POST. I was highly suspicious of my DDR266 so I removed it and no dice, still can't POST.

I heard there have been monster OC's on these Venice chips and I just can't seem to get any peice of that action. Any suggestions at all are greatly appreciated. Thanks a bunch.

(edit) I have tried to keep the RAM frequency the same but I can't find a FSB ratio in this BIOS. I just kept keeping the RAM manually at 200

I recommend reading a oc guide. I believe its your memory and your not using a divider.

I can't find a divider in the BIOS which is the problem. I can manually set a frequency but I'll still have problems.

There isn't a specific divisor setting. You have to change a setting that limits the memory clock speed. Typically you can set it to auto, 200, 166, 133, and so on. Check out one of the recent A64 O/C guides. Some of them have nice tables that show what divisors the different settings give you.

That setting you mention in the OP is what we're referring to. Try setting that to 166. Also, you might want to relax your ram timings, notably CAS and possibly command rate, before you change the divisor.

I see. Thanks a lot. I'll be sure to check that out.
