This is some pretty fast RAM, but the timings are still way high. CL5 doesn't sound all that impressive to me, but I'd imagine that we're well on the road to seeing those timings get better.

"Patriot says that its R2 1000 MHz (PC2-8000) module has been approved by Intel for use with its 955X chipset. The 240 pin module is available as either 512MB single or as a 1GB paired kit. The new memory modules are designed to operate at latency rating of CL 5-5-5-15 and at 2.2 volts."
