From Ryan @ OCZ

Just though I would let you see the great results Joey from extreme overclocking is getting with our Gold PC-3700
DDR520 with CL2 timings.[email protected]%20520.JPG

Also in our labs this weekend I personaly broke the DDR 540 with CL 2.5 mark.

and a sneak peak of some unbuffered scores with our PC-4000 betas that just arrived running @ 555Mhz
