ASUS M4A88TD-M help me get ram to 2000MHz

[QuietIce]

QuietIce, I think that you are saying that it is possible. Is that what I should be taking from that? It looks like the ram at 1867 with tighter timings beat the ram at 2000 speed. Correct?

i'm also getting that as well. Looks like 1800ish is key for best performance with low timings

1600CL7 13560/9360
1873CL8 15100/10300 (adj. 13326/9090)
2000CL9 13480/9720

The cpuNB for the 1873CL8 tests is running 2273 MHz, not 2006 (stock) as in the other tests. So the cpuNB is ~13.5% faster and the scores average ~11.5% higher. You'll also note the Everest scores for 1600 and 2000 have a variance of ~2%±, which is not really statistically significant, and that the SiSandra scores are virtually the same at < 1%±. If you include the adjusted scores Everest results are ~3%± and SiSandra is, again, virtually the same at < 1%±. You might also note that while the other tests were run at 4.0+ GHz, the 1600CL7 tests were done at a CPU speed of 3.2 GHz, though the 3.6 GHz Turbo mode may have kicked in, we don't know.

So what, exactly, did all that extra RAM speed (+400 MHz = +25%) actually do for performance?


Don't you find it interesting that the only real boost to RAM performance came from increasing the cpuNB speed?

Don't you mean increasing the FSB/HT speed?

No, the HTRef is 200 MHz @ 1600CL7 and 250 MHz @ 2000CL9 with no change in RAM scores.


If you're talking about the HT Link speed it's the same as cpuNB speed in all cases BUT the HT Link passes no/zero/zilch RAM data ...
