My previous RAM didn't have that low of timings either. So I've been putting in the timmings manually and I could get it to boot up if under 1800 MHz. Not very good for 2400 MHz RAM that costs almost a grand lol.
I will set everything to default and see if I can get the RAM any higher playing with some settings. Not looking good though.
That all sounds pretty similar to what I was getting with my 32GiB @ 2133 version of your sticks. I can get mine to boot reliably by using the 1866 settings from XMP. I'm not happy about that, but 2x the memory at 7/8ths the speed is a good enough deal that I'm putting up up with it.
I know from a bazillion forum posts, here and everywhere else, that larger capacity
sticks always imply reduced overclockability. Apparently that's also true with large stick quantities
, which I suppose makes sense. You've gotten double trouble by upping both in one go. Your sticks may not like being underclocked by as much as you'd need to underclock them, maybe? Catch-22.
Disappointing. I was hoping it was possible. I think, though, that the supported-ram chart on ASrock's extreme11 pages, which told me that eight of these particular g.skill 2133's were confirmed at 2133 (and
higher with OC), were simply lying. After the false claims about 3.4GB/s transfers with the LSI RAID, I'm not surprised, though I'm angry that I spent money buying sticks that ultimately don't seem any better than the mushkins I already had.
By the way, how well do those 2400's work if you only run 4 of them? Can you get 2500 out of them, as ASrock claims the board can do? I got the mushkin 2133's up to 2400 or so, but it was borderline. Besides, I wanted 32GiB, so OC is just plain out at this point. Maybe I should have just shelled out $500 for four of those sticks you have. I bet you can at least run four of those at 2133, maybe higher.
