**[Official]]** ASRock z87 OC Formula + (M) Thread

[nickshih]

I only tried cfr and mfr double side.. over 2400 is impossible to enable 1t....bfr i never try..haha

Seems i didnt fine tune BFR and CFR kits .

I will try to borrow the kits and check the issue .

[l0ud_sil3nc3]

CFR 1T seems to stop at 2666 regardless of voltage.

Tested up to 1.85 but for 2666 c11 1.62v was fine



finishing up with Samsung on air, what a blast!

[owikh84]

So ur issue happen on the gskill 2800 11 13 13 35 kits or 2800 11 14 14 35 ?

Gskill has new 2800 11 14 14 35 single side with MFR ic .. old one is cfr

Please check ur kits and let me know ..and u said overvolt.. any screenshot?

Alright, thanks for the responsive PMs bro.
Another kit which is CFR based Corsair Dom Platinum 2800 11-14-14 also no POST with 1T, but 2T works fine.

[l0ud_sil3nc3]

So gave my BFR a spin under cold and also to make sure 1T works and all is well:



Tighter is not always faster



I had a 7:21:5xx saved on the desktop and then corrupted Windows going for some c6 action

At the end of the session I decided to test this cpu with safe vccin (2.2v)






2c 2t valid is still on the drive and only required 1.65v.

Some 4c 8t action:

Not interested in your sex life bro lmao

[TaPaKaH]

Is there any setting that is so seriously wrong that causes my 2400C8 to fail 1200 8-11-8 at 1.65 (spec)?
Bios screens - 1, 2, 3, 4
Tried subtimings - Auto, PSC profile

CPU is capable of 1200 with PSC with any voltages, kit can do 1200 CL7/CL8 at 1.57V on ASUS.

[Splave]

try setting XMP profile option enabled even if you set manually the timings

also change
twrrd to 24
tcke to 5
trfc 100
trdrd_dd 6
trrd 6
tfaw 27

so its same as your asus timings

[TaPaKaH]

no and no. I tried another CPU to be sure and things are the same.

[Shiranui Gen-An]

So far is this the best Z87 board for memory OC?

[Splave]

no and no. I tried another CPU to be sure and things are the same.

try SA auto, IOA auto IOD auto
