iwhat are the rest of your settings, ram latencyetc.., are you using a ram divider?

2.4GHz seems about typical for default voltage, and I've seen as high as 2.8GHz using stock voltage as well. Nothing is wrong; you just happened to get a chip that does very well at stock voltage.

yes i need better ram
No, you don't need better RAM. Link

I'm saying you don't need to run it at 260MHz. You can try that if you want, but you'll gain virtually no performance, as the link showed.

Lucky you, you got a beautiful chip there. I can hit 2.4ghz on my 3500+ Winchester at 1.35v, but to hit 2.5ghz I need like 1.45v. And to hit 2.6 I need 1.5v+. And finally, for 2.7 I'd need 1.65+. So basically it's easy to OC a bit on low voltage, but as soon as you hit your stock voltage limit you'll really need to increase to get those extra clocks.

PS - I do my OCs a bit differently though. Usually what I do is have the multiplier set pretty low (like 8 - 9ish) and pump the FSB. Right now I'm at 278x9 (which is lower than I normally like it) and have my ram running at 227.5mhz.

i have my ram on the 166 divider. if i make my fsb any higher i will need to lower my ram to 133 divider EWWWWW

The 133 divider is fine (again, refer to the link).

By the way, when OCing an A64, lowering your core clock multiplier and running something like 9x300 instead of 10x270 won't really increase your performance at all, because memory bandwidth isn't a key factor in performance.

TS3433 it makes me feel better that's all.

Anyway I'm running 294 x 7.5 (which is 2.2ghz) right now at 1.2v, P95 running stable. Load temps top out at 42 :p. These A64s can really run low voltages.

I have a question about the ram dividers. Right now I have mine set to 166 because its the highest I can go (200 craps out on me). But originally I thought they were the actual ram clocks, but I guess I was wrong. Someone care to elaborate?
