After testing with voltages, I found that OCZ sticks had incredible difficulty exceeding 2.2V, an oddity for Fat body D9s. Corsair sticks ran gladly at 2.65V and Crucial’s ran best at 2.4V. In every of these cases sticks were cooled by their default spreaders and a pair of low-speed Antec 80mm Fans. After fixing with timings, I found that altering tRas didn’t help with over clock at all, and altering tRC beyond 3 didn’t help to any great extent either.

While results show OCZ sticks clearly behind rest, mainly due to their voltage problems, they still completed spectacularly but I am comparing them with best. A stellar 900MHz from PC2-4200 sticks is big in anybody’s eyes, representing almost a 70% over clock from default clocks.

One stick was capable of taking up to 2.3V with reasonable strength, though this meant running in only channel. This caused a noticeable loss on benchmarks, in particular those bandwidth intensive ones. At 2.3V, I am enabling to push stick to 920MHz at fairly tight timings of 5-3-2.

Over clocking Performance

I executed my test set up with CPU at 2.45GHz with a 350MHz FSB and utilized dividers to keep RAM as close to default as possible for first test, and as close to its maximum at every respective timing set.

• Over clocked Test Setup
* Core 2 Duo E6300 @ 2.45GHz
* 975X @ 266MHz
* Stock: 1:1 @ 3-2-2-8 (533MHz DDR2)
* 975X @ 350MHz
* Setup 1: 4:3 @ 3-2-2-8 (525MHz DDR2)
* Setup 2: 1:1 @ 3-2-2-1 (700MHz DDR2)
* Setup 3: 4:5 @ 4-3-2-1 (875MHz DDR2)

Fairly impressive results, particularly when overclocked, with top benches far exceeding stock results, supporting my hypothesis that this memory is designed for overclockers.

A remarkable oddity is Everest Read speed on Setup 1 which I confirmed with subsequent benches. Why was it lower than bench with similarly clocked memory and a lower FSB? Probably it was divider used in Setup 1 that harms the score. Also, the Everest Latency on Setup three being weaker than latency on Setup 2 shows effects of using an asynchronous ratio.
