If you are seeking out a new DDR2 kit, then make sure it’s at least 2GB! The 6400PRO from Corsair boasts the fast speed of DDR2-800 with timings of 5-5-5. Best of all though, it rolls in at 2GB and includes some purdy LED’s! (This article has been edited since first publishing due to debunked results the first time around.)
Before any testing occurs, the modules were tested at stock speed throughout the night, about 10 hours, using MemTest 1.65+. The tests proved error free as I had hoped, so I continued with the overclocks. All of the overclocks listed have been proven stable throughout multiple runs of test 5 and 8 in MemTest. The final setting, DDR2-1000 proved stable in a 6 hour MemTest run. For quick reference, here are the overclocks again:
- #1 400MHz – DDR2-800 (PC2-6400) @ 1.9v – 5-5-5-12 : 200FSB – CPU 2.8GHz
- #2 400MHz – DDR2-800 (PC2-6400) @ 1.9v – 4-4-4-12 : 200FSB – CPU 2.8GHz
- #3 400MHz – DDR2-800 (PC2-6400) @ 1.9v – 4-4-4-12 : 240FSB – CPU 2.8GHz
- #4 400MHz – DDR2-800 (PC2-6400) @ 1.9v – 4-4-4-12 : 267FSB – CPU 3.75GHz
- #5 440MHz – DDR2-880 (PC2-7000) @ 2.0v – 4-4-4-12 : 220FSB – CPU 3.08GHz
- #6 445MHz – DDR2-890 (PC2-7100) @ 2.0v – 4-4-4-12 : 267FSB – CPU 3.75GHz
- #7 500MHz – DDR2-1000 (PC2-8000) @ 2.2v – 4-4-4-12 : 250FSB – CPU 3.51GHz
- #8 467MHz – DDR2-933 (PC2-7500) @ 2.2v – 4-4-4-12 : 280FSB – CPU 3.93GHz
- CPU: Pentium D 820 @ 2.8GHz
- Motherboard: ASUS P5WD2-E Premium
- Memory: Corsair 2GB PC2-6400 PRO
- Video: eVGA 7800GT 256MB PCI-E
- Sound: Realtek HD Audio
- Storage: WD 200GB 7200 8MB
- Odds and Ends: D-Link WiFi PCI Card
- Etcetera: Windows XP Professional SP2, Windows x64 Professional SP1, NVIDIA 81.98 Drivers
I will be comparing the benchmarks to the OCZ modules I took a look at last week. They are not the same stock speeds, but that doesn’t really matter. You can check out that review here, although select benchmark scores will be used here.
Lavalys EVEREST 2005 2.21
I am using a slightly outdated version of EVEREST because I have found the newer versions to escalate scores to a level that’s just not that believable. Therefore, until I find that the scores are more evened out, I will be sticking to this version.
Everything looks keen here! I have taken a look at many modules in the past, and not too many have broken through the 8,000 barrier, but these ones stormed through. Excellent WRITE speed especially, 3,300MB/s with our #8 overclock.
At our top overclocks, we managed to score lower than 70ns latency. If you are not very keen on DDR2 then that may seem quite high… which it is. But in the DDR2 world, it usually takes a LOT of tweaking to score below 70ns. Great stuff.
Compared to the OCZ kit here, this one stormed past in the bandwidth department. 4,500MB/s!
