Man, i can't even go cas 8 on ddr3-1500 without rounding errors in prime in under 5 seconds. I've never seen this kind of underperformance

yeah that is pretty bad, does it pass memtest at stock?

Using same bios f4j, my corsair dom. are prime stable at 8,8,8,24 with 1.64v up to 1680 or so...may just be higher binned. Though mine will not boot at 1800 even trying 1.78v and 10,10,10,30 but havent tried loosening subtimings yet.

Edit: well not sure if loosening up subtimings (just standard instead turbo,nothing manual yet, or trying uncore 21 instead 20 or using F4m bios with f4j manual channel timings, or fact that i forgot change main timings to 9,9,9 but booted up fine 1800 8,8,8 with 1.68v dram had tried for hours before and no luck
