Geil Ultra pc4000

i got some guy telling me hes running his dfi board w/ nforce 4 3200+ @ 9x250 and the pc4000 geil pc400 memory. from what ive read its not so good on amd. and this guy says it bench's @ 6.6 gb/s when my ocz pc4200 enhanced latency platnum series benched @ 6.5 and works better on amd. and my timings are better. and ALL the benchmarks i can find on sisoft sandra are around the 5.8 gb mark. i think this guys full of ****. any comments?

It seems about right but of course he could be streching it a little. There are lot of factors that affect memory benches such as running processes also.
