I have an AMD Athlon 64 X2 4400+, 2 GB of Corsair 3500LL Pro, an ATI All In Wonder X1800XL, Creative X-Fi Xtreme Music, and a bunch of Seagate 250 GB SATA-2 Hard Drives and 2 NEC DVD burners.

I have been doing a lot of reading on overclocking, but I am still somewhat unsure of how to proceed. I got my system up to 2.62 GHz (238 MHz X 11), but it was extremely unstable, and started to ignore my PS-2 Keyboard.

Right now (after clearing CMOS), my keyboard is functional, and I am running SuperPi without any errors at BIOS defaults. My approach the other day (that resulted in an unstable system) was to lower the memory clock to 100 MHz, and gradually increase the CPU clock. Once I got it to 238, I increased the memory clock to 183 MHz, as prior experience told me that the system would not boot with a CPU clock of 238 MHz and memory clock of 200 MHz. This is when I ran into trouble.

I realize that the MB is new, and experience is limited, but can anyone out there suggest some settings for this CPU/MB/memory combo that have been successful?

Thanks a lot, any help will be greatly appreciated.

Welcome to XS!

I have almost the same spec (see sig) and found that the memory divider works alot better when set to 166 or 133. 183 caused instabilty for me too and wasn't recognised in the bios post.
My system runs fine @
Memory 2.8v
2.5-2-3-6 1T on a 166 divider

CPU
opty 165 at 1.3v(+0.2v)
290x9(2.610ghz).

Chipset
K8 to NB 600mhz - all others auto.

This is with all the overvolt options enabled and EEC disabled.

Hope this helps.
