Hi, my A64 broke basically (Had it on a mad overclock prob did it). So i replaced it with.

Intel E5200
Asus P5K Pro
4gb Geil PC6400 Reaper Ram

Now I forgot how to overclock lol, I had my 3800X2 Toledo at 2.9ghz. I want to overclock this its currently at 2.5ghz.

I kinda remember how to overclock the A64 but this is totally different I don't know how DDR2 and the figures relate to FSB and stuff.

Any help appreciated, even links to a dummies guide will be welcome.
 
Im getting weird results in CPU-Z.

I've updated my BIOS and put FSB to 200 and Multiplier to 12.5 (thats stocks) and also ram at 800MHZ (also stock).

In CPU-Z my Core Speed goes from 2500.0 Mhz to 1200 Mhz, Multiplier changing from 12.5 to 6.

Also I noticed ram says at 400Mhz but at 1/2 ratio? Isn't that 1/1 ratio? I'm worried that my pc is running below half the speed it should be! Is there any quick benchmark out that I can check just to see if its performing at stock?
 
That's Speedstep. It cuts the multi when the CPU does not need to be fully stressed, therefore cutting back on heat and power usage. If you want to switch it off, turn off C1E and EIST in the BIOS.
 
It shouldn't; I've never found it to anyway. Some people say that it does at a really high clock, but I wouldn't know. If you start clocking and find it unstable, you can't lose anything by turning it off and seeing if it improves your stability. Personally I quite like it being on-don't see the need for my CPU being on full blast if I'm just browsing the web.
 
Yeah, think i'll turn it off when overclocking and once I find a stable clock i'll put it back on to see if its stable, think I got my head round how it works nice thanks. Will post with my results later.
 
Cool cool, I'm quite interested to see how this goes! If it's any good I may buy a 5200 myself.

I learnt to overclock about a year ago-found that the easiest way to do it was to dive into the overclocking section in my BIOS, have a look round, then come back here and match it to the guide. The guide is a lot more understandable once you work out what everything refers to. Good luck!
 
Looking forward to some results myself, though I should be able to have a play with one when I get home :)

Just hope for once I actually get a good clocker! I have the worst luck when it comes to good clockers :(

Don't want to go over 1.45V, but am hoping to get at least 4GHz :)
 
Right just been having a quick go, upto 3.4ghz at 1.275volts, my 2nd core is very very weak compared to my first. But CPU-Z again reports different voltage than my bios at 1.25, same as Asus Probe that says 1.25. Which is right my bios or the programs? What typical volts do people run these at 24/7? Just wondering what my limit should be.

My pc cooling is terrible have a coolermaster wavemaster thats being no help to this overclock and I got the Akasa AK-965BL Blue LED CPU Cooler (Socket LGA775) one of the cheapest coolers around lol.
