ASUS Z87 Motherboards - Overview, Guides and Official Support

[cstkl1]

think Shammy alread said these are offset so no reported in UEFI - that's how it actually works. OS reading could be bugged or whatever as well.

As for tCPDEN etc - these are power saving features, time from a transaction to power down. If you disable all power saving features of DRAM I wouldn't bother with this kind of "tweaking" myself. I am being sarcastic with that comment, but I think you'll get what I mean :P

The salient tweak features of this chipset are already pointed out in the guides. If you want to move outside that - don't expect much if any return for your efforts.

Change values till you get what you want. Min internal spacing for this will be 4 clocks - not many DIMMs will do that at high freq.

nah i always like my trtp and twtr to be the same. Not aiming for minimum. Cause at default theres a issue with memtest, on cold boot it always shows error on test 1. But rerun or restart it disappears. Changing this solved it. Just seriously want 2600 1t.

Btw thanks for making this board. Its awesome.

My biggest headache with haswell is digital i/o n twrwr_dr/dd. this is whats stopping me atm. Also need this to be stable to have a shot at 2666 . Personally gut feeling is telling me this is where trdrd 4 taps out.

If any board can do it .. It will be m6e at 4x4gb. The exact settings to make 2400mhz 1t work is what did the trick for 2600 2t. So hoping 2600 1t will do for 2666 2t
