ecently I replaced my A64 3500+ with a Retail Opteron 148. Performance improved across the board with a server based chip now binned for socket 939 desktop applications, extra L2 cache onboard. As mentioned previously I reviewed TWINIX2048-4000PT
on the same motherboard/BIOS but had no where near as successful an overclock at 265FSB DDR530. Conclusion:
is a high performance beast with glowing eyes. Surpassing 580MHz was a breeze and while the memory wasn't completely stable in all benchmarks at DDR580 (it failed only in Far Cry) it was 100% stable at DDR570 including Far Cry. Had I spent more time tweaking the DFI Phoenix-Award BIOS I've no doubt I may have taken this product further. I weighed the time spent and the speed attained at SPD and felt it wouldn't be worth it to the average PC-Enthusiast to push the memory that far which would involve testing the product with a full benchmark suite. Only using this method can you be sure while Gaming or running an important program their system won?t randomly crash.
570MHz was the best stable speed and given the memory kit size this was definitely high performance. I did experience some problems with the DFI BIOS in which I had to manually set CL3-4-4-8 to maintain stability at and above 550MHz (275FSB). I verified these timings using CPU-Z 1.34.1
which indicated these were indeed the SPD programmed timings. Corsair has chosen some high quality DRAM IC's for its TWINX2048-4400PRO an attribute made apparent not just in its overclocking prowess, but its compliment at 2GBs. PRO
Stable to DDR570
Runs 2.5-3-3-6 to DDR480
2048MB kit size
Ergonomics LED look great in window case
Decent price with $25 rebate until 6/21
Could OC slightly higher, given kit size this is still greatP
rice at time of writing. Corsair seems to be offering a $25 mail in rebate until 6/21 for US readers:$261 ZipZoomFly with $10 Instant rebate and $25 Mail in rebate.
$271 Newegg after $25 Mail in rebate.
Thanks to Corsairmemory for the loan of the kit.
