I recently upgraded to a windows 7 64-bit computer with a 4gb kit of g-skill 4GBRL ram in it. I have tweaked everything in my system for efficiency, last of which was this ram. The stock timings are 9-9-9-24-40 2T @ 1.50 volts..
I have been able to tighten them to 8-9-8-24-40 1T completely stable @ 1.561 volts, 12 hours+ prime95 64 bit on 4 cores and 7+ passes in memtest86+.
Going to 8-8-8-24-33 1T is a different story, I have not got this stable even @ 1.63 volts and I refuse to go any higher because I value the lifespan of my ram more than any marginal gains it would bring. Actual tests at this speed showed performance degradation in some areas actually, not to mention being unstable.
My question here is what I should be running the 'row cycle time' any lower @ 8-9-8-24 1T? Is there an optimal setting for 'row cycle time' at this timing, and furthermore is it not optimal to run the first three settings @ 8-9-8 instead of having them even across the board? (8-8-8 or 9-9-9) I have seen in AIDA64 tests that the memory read, write & copy times benefit from these timings, but these are synthetic benchmarks to the best of my knowledge, and I would like to know if the 8-9-8 timings would work best with a certain "row cycle time"?
Is ram best run with the TRP, TRCD & TCL (8-9-8 currently) @ equivalent numbers (8-8-8, or 9-9-9) and what should the 'row cycle time' be set to with 8-9-8-24-1T timings, optimally?
I am a novice overclocker with very favorable results recently.
System Specs:
AMD Phenom x2 555 BE 3.2ghz unlocked to x4 3.6GHZ (200x 18) 50 degrees load air cooled in a centurion 5 II case w/ 5 fans (cpu, rear, top, HDD, side panel) w/stock CPU voltage.
4gb G-Skill 2x2 4GBRL Ram stock 9-9-9-24-40-2T @ 1.50 volt-- running @ 8-9-8-24-40-1T 1.56 volt, ddr3-1600 (800mhz)
ASRock 870 Extreme3 mobo, NB 2400mhz (x12), ht 2000mhz
Thank you g-skill for making ram that I trust in any system! I know the voltage I have the ram running at is only slighly above stock 1.5 voltage, but I would like for it to last a while, and be reasonably tightened to it's potential-- that's why I'm asking. I was very happy to see it run flawlessly with 1T settings and would just like to match the row cycle time to this efficiency level.
Thank You!
