I recently purchased a dual-channel set of G.Skill's DDR2-1066 Cas5 Ram to replace some failing Crucial Ballistix DDR2-800 sticks. From the second I installed the new sticks, I of course began testing their limits.
They are rated to run at between 2.0-2.1v, and for my tests I selected 2.1v from the motherboard's BIOS (GA-P35-DS3L)
I ran a handful of different different timing configurations; For each one I used SetFSB to push the memory frequency higher until Orthos Blend was no longer stable (or the computer froze), and recorded the highest stable clock for each setting. Note that the subtimings stayed constant throughout all the tests, and were set based on the EPP recommendations for 533 MHz (DDR2-1066)

RESULTS
6-6-6-20 : 690 MHz (DDR2-1380)
6-5-5-20 : 631 MHz (DDR2-1262)
5-6-6-17 : 590 MHz (DDR2-1180)
5-5-5-15 : 588 MHz (DDR2-1176)
5-4-4-15 : 475 MHz (DDR2-950)
4-5-5-12 : 500 MHz (DDR2-1000)
4-4-4-12 : 473 MHz (DDR2-946)
4-3-3-12 : 360 MHz (DDR2-720)
3-4-4-12 : 365 MHz (DDR2-730)
3-3-3-10 : 360 MHz (DDR2-720)
Considering these tests were only performed at 2.1v (and may have even been less due to any voltage droop/drop on this board), these are excellent results that get up into DDR3 speed territory. Based on the performance of this Ram Kit and its price (To view links or images in this forum your post count must be 2 or greater.
