ASUS Z87 Motherboards - Overview, Guides and Official Support

I think most of those kits were out long before Haswell if my memory serves me correctly (excuse pun). Which means the XMP settings they are programmed with were conceived before the platform,...

I have the Team Xtreem single sided Hynix here - its a kit I purchased early last year. Works fine on my Extreme board - mind you CPU has a good IMC...


When you say LOOSE timings, are you taking third timings into account? Haswell needs looser tRDRD on some kits over IB. I don't want to argue either. Just giving you some of the fixes I know of. Up to you if you want to use or not.

Both sets of TeamX 2666c11 [MFRss] were purchased two weeks ago SN# 5130314044
tRDRD was 6
REF cycle was increased to 363 and then 460
tWCL 10

this set was introduced to the max DDR voltage available on this particular motherboard, also- cpu input 1.9V

bottom line is ,this is mainstream mobo and bioses are not optimized as other higher-end motherboards offered by Asus,I understand

Not sure if the wink implies something untoward. The ROG boards are engineered in a different way on the DRAM side - as they should be as that's the target audience. As a DRAM enthusiast, you should be able to tune a board and understand how XMP works - plus understand IO variance between platforms without thinking you are being treated like a mushroom (kept in the dark and fed bull).

Change some of the other turnarounds too if you want the kit to work.

Now if it's performance oriented clocking you want, then yes go for the ROG boards as that is what they are made for. If you knew this in the first place, you would have waited. The mainstream boards are engineered for mainstream overclocking use. They employ layouts "closer" to Intel spec - we have very good reasons for that as well. For the special stuff, we put different emphasis on ROG.

Do not assume that all the optimizations are UEFI based. They are not - the layer count and routing comes into play as well (as does MRC which can change, but that's up to Intel, not us). The fact you asked for a UEFI update initially suggests you think this can be cured solely via UEFI - too many factors to assume its just that. Your usage scenario is suited to ROG, so that's what you should be using.

There you go, it's out in the open without needing winks.
