What set man? I go highest at 125 strap

please set command rate 2T first

having issue with BFR and CFR IC to run 1T now ... others alll working perfect

I actually did set 2T manually. I may have to go back and look at screenshots from successful 2933+ runs with these kits on the Gigabyte Z87 OC Force and look at the timings that were set.

Aaand...today my Patriots decided they wanted to play nice. Absolutely no changes at all to the settings that weren't working last night.:shrug:

set boot cycle to 3 ,sometimes it takes 4~5 times (55) and smooth sailing after that :yepp:
A3-hit reset
D9-wait
- semi-tight timings are better on some IC's then semi- loose
-start with tREFI high ,I found refresh intervals to be somehow to tight on some of the profiles

managed to get my PSC to run 1200 6-11-7, but can't get 7-11-7 or 8-11-x to work with exact same settings :shrug:

Did you leave trdwr set of timings auto?If manual the tighter tcl and twcl get,the tighter you can go on those and i experienced problems when not setting those 3 trdwr accordingly...

trefi higher means tighter actually,in other means you get little boost setting in higher than default 7936

bro setting 1 for thirds is slower than setting 4 for me

Subs are so tight on this board! It makes it really hard to do high clocks with double-sided MFR. Just compare the settings from the 2933 preset to what passed 32M on the Gigabyte board.

Z87 OC Formula 2933 preset (auto subs are pretty much the same)

I've been trying to replicate the settings from the Gigabyte but it seems to make things more unstable. Any tips? Brute voltage isn't working, these don't like much more than 1.8v.

I am going to venture and say you are trying with twcl 8? If so try 7 or preferably 6 even with 8-11-7 or 7-11-7.

Z87 OC formula series tool update


Formula drive update to 1.0.61.3 , it is including lite version and full version inside .

1. Fix dram voltage issue when u set higher than 1.85

2. Fix cache ratio issue

thank you nick i was wondering what was wrong with vmem but thought it was just me chopped os...:up:

What ram (ICs) on your try Splave ?

I tried alot on MFR sometime 1 better over 4 but from average i think it not different between 1 to 4 for third
however for SAMSUNG ic i have tried with 1 and not easy to boot or not boot and for CFR if setting 1 on third
it will lost for Mem BW

So i think value 1 on third have some real value for MFR like tWRWRDR/tWRWRDD cause some time i saw
it by auto which 1 or 3 value from many time i tried

btw. i will try more and will update about this it real or not for value 1 on third ;)

Sorry, no pics of IOL and RTL from the Gigabyte board to compare to the Asrock.

Timings for tertiary side vary._dd timings have impact when all 4 slots are populated,if you have only 1 stick/dimm u can set 1-7 whatever,performance is ~same,if you run 2 sticks/channel for high speed(2600+) values of 6-7 are needed)i need 6 for both samsungs and psc otherwise no boot)._dr timings reffer to single rank/dual rank,e.g single sided memory or dual-sided,if you are running single-sided sticks like 4GB MFR then 1-7 performance not make a difference,when benching double-sided memory 4 is optimal.

Here are the RTLs from the OC Formula.

2x8GB seems fine for clocking 2933+

Hey man, where did you get the desktop background from, looks good. ???

My Settings with Win 7

Which settings i need for better/lower latency?
i have don?t found until yet

Experiment & see what works for you.

See this post http://www.xtremesystems.org/forums/...=1#post5200470

My ram runs stable for 24/7 at those timings with the exception of tras 22, trfc 120, trdwr 13, trdwr_dr 13, trdwr_dd 13 RTL & IOL Auto, twr 6 1.65v

Thanks alot Alex this details very helpful to me :up:

btw. a bit more question on mind my i feel it different performance for 4 and 7 if benching on Windows7 x64 :shakes:
