    0044 = Air/H2O. Fixes memory divider issue, normal BIOS, have memory fail 3 counts recovery mode.
    0045 = LN2. Fixes memory divider issue, no fail 3 counts recovery mode. Can use retry button forever

    Nice bandwidth dude, but TRRD_S and TRRD_L are wrecking your latency there. Can they not tighten up? With sticks that good 4/4 should be possible, maybe even 3/3? I would expect sub 60ns, my lowest is 63.2ns @ C16 with double sided 16gb sticks.

    4800 C18 bin...crazy sticks . T-force 4500 C18 are tempting me, I've had the browser tab open for about 2 weeks now.

    Thanks PILsY
    4 is the min. value. Imo 4/6 better with 12-9-9
    60ns with fclk 1900 probly possible with cpu on single stage
    fclk cold bugged @ 1500, max out @ 1400ish on ln2

    No worries, that's looking way closer to what I expected. 12-9-9 is ridiculous, utterly ridiculous

    If you want a superpi boost then B-Die can run TRCDWR at half cas latency. i couldnt get it fully stable, but it ran most benches (16-16-8-16 in my case). That'd be 12-9-6-9-18-1T-27 if you wanted minimum possible off those primaries. Like I said, no stability promises but that kit you have is godlike...

    The only thing putting me off buying a high bin 2x8gb kit is the performance hit from running single sided puts me pretty much back to where I am now with double sided at c16. Ive tweaked up to 56k read, 55.5k copy and 63.2ns stable (no BGS/BGS_Alt options for Gigabyte so im down a few thou in AIDA), but that really is all I can get. Looks like C12 flat timings with average subs on single sided will be around where my C16 flat timings with maxed subs are on double sided.
