Need help with an OC

What is a good range to overclock an AMD A64 X2 4400+? I'm currently running fine at a moderate 2.31, which is about a 5% increase. Can I get more out of this thing? I never hear too many people OC'ing the 4400+.
 
see sig :D

for an indication of how others are doing with their 4400+...

Well, that answers that question. At 5%, I left my VCore at 1.408. Should I up my voltage or is my OC so moderate that I'm fine?

If I do a 10% OC, what should my VCore be?
 
Download prime95. See how high you can get your proccessor on stock voltages.
 
Honestly, you could get probably a 200mhz OC without any Vcore changes. My 2800 will post 400mhz over stock stable (450 it starts to get flaky) without any extra voltage. A huge jump to 1.525 is then required to post anywhere between 450-800mhz over (it's as stable at 2.77 at 1.525 as it is at 2.46... strange).
 
I'm currently at a 2.31, but I would like to go to a 2.4 OC. My RAM is my next question. I have 2x 1GB XMS 3500LLPRO at 2-3-2-6 T1 @231MHz. Now if I OC my CPU to a 2.4, do I need to change my RAM timings? How much more MHz do I need for a 2.4 OC? 240MHZ?

I just don't want to create a bottleneck. I'm a total newbie overclocker so any help is appreciated.
 
90 mhz increase in cpu speed and 9mhz increase for the ram should be fine i don't think
you would have to hurt your timings too much if anything, if you can't do it on the timings
you have now then i would raise them to like 2.5/3/3/8 at most anything higher would
really hurt you performance wise. But you should be able to hit even 2.5ghz with those
timings without taking a huge performance hit from the ram. IMO

Your going to have to use a divider.
 
If you're new to overclocking, you'll want to read this guide from Eclipse. It's easy to understand, and great especially for new overclockers.

Don't be afraid to run a divider; memory bandwidth really doesn't have a significant effect on applications (unless the're ultra bandwidth intensive).
 
Eclipse's guide is amazing and extremely helpful. But it's the RAM that is killing me. I'm just not grasping this.

If I set my HTT to 220, my muliplier is 11x so that will give me a 2420MHz OC. That part I get. When looking at CPU-Z, it shows memory as CPU/10. So going by that, my RAM would be 2420/10, which works to a 242MHz, but that's a 1:1 ratio. So something is not right. Should I not use CPU-Z's CPU/10 to get my RAM OC?
 
If your RAM is running at a 1:1 ratio, it will run at the same speed as the HTT.
