If you are in the market for a 1GB DDR2 kit, then this kit proves to be a great choice. Despite being value memory, it overclocks quite well with the ability to keep stock timings.
- CPU: Pentium D 820 @ 2.8 GHz – 3.85GHz on AIR
- Motherboard: ASUS P5WD2 Premium w/ 0606 BIOS
- Memory: OCZ 1GB Gold PC2-5400 XTC 4-4-4-12
- Video: eVGA 7800GT 256MB PCI-E @ 490/1.15
- Sound: Realtek HD Audio (Onboard)
- Storage: WD 200GB 7200 8MB
- Odds and Ends: External WD 200GB 7200 8MB via USB2.0
- Etcetera: Windows XP Professional SP2, Windows x64 Professional SP1, NVIDIA 81.98 Drivers
Before I attempted to overclock anything, I ran MemTest 1.65 overnight to make sure there were no errors at stock. When I find a new setting I want to test, I load up MemTest again. To make sure my current setting is stable, I run MemTest’s #5 test in a loop of 3 and it’s test #8 in a loop of 2. Once that’s done, I consider it a stable overclock and continue up the ladder. My highest overclock is one that still uses a stock CAS setting. Here are my results:
- FSB 200 (DDR2-667) – 4-4-4-12 (1.9v)
- FSB 200 (DDR2-667) – 3-4-3-8 (1.9v)
- FSB 220 (DDR2-733) – 3-4-3-8 (1.9v)
- FSB 240 (DDR2-800) – 4-4-4-8 (2.0v)
- FSB 267 (DDR2-800) – 4-4-4-8 (2.0v)
- FSB 275 (DDR2-733) – 4-4-4-8 (2.1v)
- FSB 275 (DDR2-825) – 4-5-5-10 (2.1v)
My final overclock attempt, DDR2-825 proved error free in a MemTest run over the course of 10 hours. I am quite impressed by the overclocking ability here, I was able to push them further than I originally anticipated. Granted, I had to raise the TRCD and TRP, but the benchmarking results prove that it’s hardly an issue! Speaking of benchmarking results, let’s get right to them.
EVEREST Ultimate Edition 2.20
There is a newer version of EVEREST available, but it’s results were jumping all over the place which is why I chose to use last years version. Each test is run three times and the average of the three are the final result.
Since I am pretty new to the DDR2 world, these results impressed me quite a bit. At stock speeds the modules yielded near 6,000MB/s read and overclocked was just short of breaking through the 8,000MB/s mark! We can see that the overclocking tightened up the latency quite a bit also. 20ns difference from stock to overclocked is quite a large difference.
