I believe the valu ram does not carry the lifetime warranty...I have gskills and the higher end line...It will do cas 2,2,2,6 at pc3200, but I cant get this stuff to run rated speeds of 550ddr at cas 2.5,3,3,7....however I think that may have to do with the memory controller and my high HTT (295-330 depending on the multi)
I have talked to the ppl at gskill and I actually think the stuff is more tested on prescott systems and I dont think it is that good on A64 systems if you plan on ocing and have a high OC planned....
that is my 2 cents now from 4 sticks tested and sizeable amount of ram tweaking testing....Take it for what it is worth...
Edit: I can run 550ddr at cas 2.5,3,3,7 but I have to drop the multiplier to like 8x 277 to get it to work and even then I haven't done an extensive memtesting like I normally do...the problem was that that was dropping my cpu 400mhz to get it to work...At 8.5x277 it was not stable....at 9x277 it needs cas 3 to run and not all that stable....
I am not ipressed....
I am thinking of getting some ballistix so I can run cas 2.5,2,2,7 timings like zebo at 480-500ddr range....
