Makes no difference, I've found the above latencies only really need changing when I switch cpu's. Ive used 1gb tccd, micron and cheap value and now 2gb of uccc, and these settings havent changed much. I guess you need to get the sweet spot with these specific settings to get stability at high fsb regardless of ram.
The "trick" to get quick stable dram settings on these dfi boards is to first use "Set Optimised Default" in BIOS,
Then set the HTT to the rated speed of your ram, do this
before booting into windows and then in windows write those settings from A64 Tweaker down and set them in bios manually next boot...otherwise you will never get a good start. knowing all your dram settings and switching them off auto will make for a more stable system. auto=bad
Ok, once you have input the "main" ram latencies manually into the bios thanks to A64 Tweaker you can start fiddling with the stuff that makes a big difference with your max overclock
when on a divider.
try these out for size 1st…….
Max Async Latency - 08.0 Nano Seconds
DRAM Drive Strength - 5 (weak 3)
And try these 3 relaxed tref settings out and see which works best for you, 1168 work best for me...
0908= 100mhz(7.8us)
1032= 133mhz(7.8us)
1168= 166mhz(7.8us)
This way is about the easiest and quickest way I found to get good dram setting on the dfi board.
edit: make sure your off the factory flashed bios and on the 623, or 704 bios.
the early 310 or 510 bios just wont do for overclocking
