Yes,.....in this case you will eliminate any fault from memory side,first.

Edit:
My 3770K is far from "golden",but I know excatly how much voltage I need for any multi (45-50).
The best thing is to apply"Optimized defaults" in BIOS and set voltage only for CPU (Vcore,LLC Vtt,IMC,etc...)
After you know what your CPU is capable of ,next step is memory.

Thanks you so much, tonight will try to OC again without X.M.P profile, hopefully can success this time

No doubt.

Hi guys, what is tRFC (Refresh Cycle Time)setting? where do i change the setting? how do i determine i insert a correct timing for overclock the ram?

I try with new setting this time

Vcore = 1.32
LLC = Turbo
Extreme memory profile (x.m.p) = DISABLED


but i still getting the 0x0a error code when run prime95 for 1 hour +

but then i do have passed the Intel Burn Test with standard stress test, so is my system stable ? or i still need to increase Vcore ?

hmm, this time i increased vtt to 1.08v with the following result after run prima95 almost 2 hour and i have the vcore from 1.344 to 1.35 read from cpuZ during test

Set Vtt to 1.10V as suggested earlier.
Try this setting with LinX 10-20 runs.
Which Prime95 version you run?
(I using IBT or LinX,which is sufficient for my view of stability)
You can check also memory with Memtest86+ v4.20.

Can you show Tweak Launcher next time when you testing.

Asrock Z77 OC Formula.....BIOS 2.00

ftp://download.asrock.com/bios/1155/Z77%2...la(2.00)ROM.zip

1. Improve memory compatibility.
2. Support Intel UEFI RAID configuration in BIOS setup.

Got a better BBSE kit which just did 2500 8-11-7 stably. Too bad 8-10-7 is not possible I believe it needs cold or stonger IMC to shine.

hello guys..just wanna ask about overclocking ivy bridge..currently one of my ram slot is dead..running on single channel now..does it affect the cpu overclocking?

RAM wont affect CPU clocking so does the faulty DIMM slot. Just that you're running at slower mem bandwidth resulted by the single channel. Why dont you try OC your CPU and see how? Why dont you RMA the board?

hello guys. long time hasn't post here. need help oc'ing my samsung ram. specs on my sig. no screenshot yet coz still running memtest. right now my timing is 9-10-10-10 @ 2000MHz. based on most ram timing I see, the tRAS value is around 20~28. is it possible to have it at 11 like mine?

tRAS = CAS+tRCD+tRTP in your case the most efficient tRAS is 9+10+10 = 29 and above

Asus MVF OC Guide

thanks for the link. just tightening and now reached 8-9-10-27-1T. running memtest now. will post screenshot later

Anyone have idea on this?

Asus MVF OC Guide

It's in the RAM Timing Control menu in the BIOS settings.



AFAIK there's no specific calculation formula for tRFC but the lower the value, the faster the Super Pi benchmark will score. I will just leave it to auto for daily usage.

Overclocking my ITX Rig for 24/7 use... Using Corsair H80 + 2x Scythe Gentle Typhoon at full speed. Add to front page pls



Also, anyone else using this mobo and ram having problems OC'ing ram past 2000MHz. Can't even POST when set to 2133MHz or more even at very loose timing

Very nice!

So I just bought a Samsung based kit of G.Skill TridentX 2666C10 2X4GB

2666 10-12-12-25-1T @ 1.6v

Hi all,

My CPU temp sometimes exceeds 100c while on stress test via Prime95.Is it normal..??

Btw,my spec is below..Thanks!

Its normal if u clock ur proc at high frequency. how much u overclock ur processor and how much is the core voltage? easier if u post your cpu-z reading
