Hardcore DDR2 RAM by Corsair, G.Skill, OCZ and Patriot

G.Skill F2-8500CL5D-2 GBHK (2x 1 GB)

This memory makes most sense at its default speed of DDR2-1066 (PC2-8500), but at increased voltage and tightened CL4-4-4-12 timings. It's important to note that the product is rated for CL5-5-5-15 timings; we were able to achieve the quicker timings at an increased voltage of 2.4 V.

Unfortunately, this G.Skill RAM did not work on MSI's P35 Platinum at all.

Speeds And Timings

The G-Skill PC2-8500 RAM, which is specified for CL5-5-5-15 operation, ran reliably at quicker CL4-4-4-12 timings at DDR2-1066 speed when we increased the voltage to 2.45 V. At 2.4 V, Prime95 still reported errors.

Overclocking to DDR2-1173 speed was easily possible at 2.45 V, but the timings had to be relaxed to CL5-7-7-22.

The same was necessary as we went to DDR2-1200 speed: it was only reliable at CL5-7-7-22 timings.

Finally, DDR2-1219 was the fastest clock speed we could achieve. However, this required another relaxation of the memory timings to CL5-8-8-22. Clearly, squeezing out a few megahertz at the expense of memory timings doesn't make sense.
