I'm sure it rocks, but I'm not sure you need to spend that much
I've been evaluating the Kingston Value Ram in my 845e based P4 system. I got a 512MB PC2700 stick for my sister's machine, and surprisingly enough, it got stuck in my machine. It runs at PC3500 speed (432MHz on my board, 162 at 3:4) on only 2.7V with cas 2,7,3,3 timing on my BD7-II. I just got in a second stick, the 256MB version this time. It performs identically to the first one. With more voltage I am sure even more clock speed would be feasible, but I am limited at present by the cpu. Very nice ram.
The part numbers I am using are KVR333X64C25/512 and /256. They have Kingston (?) branded chips on them with the following number: D328DW-60. I'm not sure if this is a winbond chip or what but it really performs. Given the stability it shows at PC3500 speed I can't help but wonder if the expensive stuff isn't the same module with a heat spreader attatched...
