Overclocking

was used to test for stability thoughout our overclocking tests. If it failed, we'll be clocking back until the tests pass.

The first test was to see if we could run the OCZ DDR PC3200 Dual Channel at its rated 400MHz, 2-2-3-5 T1 settings. This is always a good first step just to make sure your ram is working as it should be. Remember that the specs on the site say 2-2-3-5 and my SPD settings are 2-4-4-9, but the two settings passed the test.

Everything was running well so we will go up 1 MHZ at a time until we reached our maximum overclock. As we approached the higher speeds, we had freezing issue, and we've had to increase the memory voltage up 2.7v to maintain stability. At 2-2-3-5, we managed a maximum over clock of 230MHz (460MHz DDR), but the ram fail the Memtest86 tests. Clocking back down to 22MHz (440MHz DDR) resolved the problem.

I had trouble with CPU-Z software didn't want to detect my ram. We downloaded old versions and new versions, but for whatever reason, no dice. So I have included few charts to show my results...

200MHZ(400)2-2-3-5

230 MHZ(460) 2-2-3-5

Test Setup

Abit NF7-S nForce2: Athlon XP 2500+ (11x166: 1830MHz), 2 x 256MB OCZ EL DDR PC3200 Dual Channel Platinum, MSI FX 5200, 40GB Maxtor, Windows XP SP1

Test software will be:

SiSoft Sandra 2003
PC Mark 2002 Memory
PiFast
Quake 3
UT2003

We'll be presenting benchmarks at both the ram's stock speed (400MHz), as well as at the overclocked speeds, with the timings as shown earlier this page. Tests were done with the FSB and memory speed syncronous @ 166 (333DDR, 2-3-3-5), and asyncronous for 200MHz (400DDR) and up. At all FSB settings, timings are 2-3-3-5
