I wonder if anyone can my mate with a speed and timing problem he's having with his RAM?

I have 2 x 1GB kits of Kingston Hyper-X RAM, with 4-4-4-12 timings at 800mhz. However, the RAM is showing as 667mhz with 5-5-5-15 timings. I've checked the bios & all tweaking options, I can't set the speed anywhere, though can adjust the timings.

"Each module pair has been tested to run at DDR2 800MHz at low latency timing of 4-4-4-12 at 2.0V. The SPD is programmed to JEDEC standard latency 667Mhz timing of 5-5-5-15 at 1.8V. Each 240-pin DIMM uses gold contact fingers and requires +1.8V. "

Timing Reference: 667MHz 5-5-5-15 at +1.8V / 800MHz 4-4-4-12 at +2.0V


nTune was showing my RAM had 1.85V, so I upped that in the bios to 2V. It's still showing as 667mhz... Do I need to lower the timings to 4-4-4-12 before the 800 speed will apply? Or is there something I'm missing? I bought this RAM for the 800mhz & 4-4-4-12 timings, so a bit annoying that it's defaulted to the slower rates

Thanks in advance.
