G.skill DDR500 won't run at DDR500

I've just bought a 2GB G.Skill PC4000 kit to replace my old GeIL 1GB value ram. I was running the CPU (Opteron 170) at 250x10 and used to have the GeIL on a 333 multiplier. After installing the new kit I set the memory to a 400 multiplier so it would run at 500Mhz. Unfortunately the PC was very unstable and would not even start a Prime95 run at these settings

I then set the CPU to the default speed (200x10) and set the memory to DDR500. This time the PC wouldn't even boot! I just got a load of beeps and a blank screen.

Am I doing something wrong or is this RAM defective?

Thanks for the replies

. The MB is an Abit AN8-32X. When I had it running in Windows at 250MHz CPU-Z reported that the timings were 3-4-4-8. Would it make a difference if I set these in the BIOS? I had left the voltage at 2.6, but also tried 2.7 with the same results.

I'll try the memtest later - should I try it when running at 250Mhz or 200Mhz?

Hmm I just found this:

If I read it correctly, I need to use 2T rather than 1T. Does that sound right?

Mine's the 2GBHZ kit btw.

ITR there's a post on the forum I mentioned earlier for the DFI boards:

I've currently got mine set at what they recommend for the Abit board - 3-4-4-8 DDR400 with 2T command rate. It's stable in Prime95 but I keep getting crashes in WoW where it just bombs out with a page fault.

Think I might have to eBay it and get something else.
