**[OFFICIAL]** Asrock Z77 OC Formula Overclocking / troubleshooting/ Discussion

[Alex-Ro]

1.085 i see there,not so high in my opinion,it;s pretty safe for daily use.

[emertX]

For booting I needed 1.15V VTT1 & 2!
Now I booted with 1.07 on VTT1 and VTT2 @ default - 1.034!
But it runs like hell! Especially with these subs
Here with linx running.

1.15 is pretty safe dont worry hahahaha gogogogo let's overclock

u can use vtt1 115v vtt2 keeps default

[emertX]

Great...I just came into windows with 2600 10-12-11- @ 1.64VMEM and 1.11 VTT1 and 0.96 SA
Afterwords with 2666...but my timings have been too low! couldn't run more then one aida bench

New bios updated

Improve timing for PSC and BBSE with 2400~2600 memory ratio
My psc is flying now . 8 12 8 28 1t 8 86 4 4 4 16 7 2652mhz directly boot into os memory 1.835v

[emertX]

So, I found the problem!
@nick
the booting voltage for the vtt is too low! I think, that's the reason, why my mem's won't be dedicated.
I can boot now with vtt1 1.076, vtt2 default, vcssa 0.958.
In windows, it's no problem to lower the voltages! Booting with 2666 needs 1.15 vtt1 and 0.98 vcssa, but in windows, I'm able to lower the settings to 1.08 and 0.96.

Please have that in mind while constructing the next BIOS

Little bit try for cas 7 on my PSC kits and can holder for Spi32 max at 2520MHz it cool but will try again for last new bios

btw. 1.75V Vdimm, 1.25Vsa/vtt

please try 1.83v 8 11 7 , u will get boost ! CL7 is useless for PSC chip ...CL8 gets better performance .

i have auto rule for different memory clock speed , u dont have to set the vtt and vccsa actually .. it will raise up automatically .

Vtt and Vccsa still depends on cpu quality . some need high , some not . But it is great that u make ur memory clock boost now . congrats !

emertX, the motheboard must boot with VTT 1.050-1.057 this is Intel stock.
The memorys with higher XMP( 2400-2666) set with the XMP the VDRAM voltage but also the VTT(1.100-1.150v).
On Samsung you don't have profile at 2400 neither at 2600.
On MV may on AUTO the board set's a better VTT.
On Asrock may be on AUTO even though oc is in , the board just let it to default - 1.050v.

Or may be i missunderstood, when fail to boot your VTT was on AUTO or MANUAL 1.050V?
It's just that you have to set the voltages manual, other than that ....


Man i have to have a lot of patience, one more week and i will have the board to....
I have a PSC kit and BBSE kit . I hope they do at least 2600.

Thanks Nick i'll try again tomorrow with your post new bios and Yessss you right C8 better over C7 from i try before on other MB

[nickshih]

cool , ur event in Thailand is cool . please send me some pictures ! nice work

Thanks! So you mean, I'll have to let the voltages @ auto???

Here's a message from vita. I should give it to you!

Hi Nick,

Thanks for your mod bios(0.31M) good work.
However, I have a problem, if I set the offset mod, LLC Level.5, takes over the board level only. 1, there is a bug?
you Would be very grateful if you could help me.

greeting Vita

So...I'll test Auto config now!

So...I'll test Auto config now!

VTT1 is more important for memory OC , i have auto rule . Normally 1.15~1.2 is enough for 2800

VTT2 u can leave it auto

PCH1 is more important for BCLK OC , i have auto rule . 1.15v is enough

PCH2 u can leave it auto

VCCSA 1.15v is enough for even 2800

[emertX]

Thanks!
And now my last question concerning mems
Which would you prefer for that stunning board?

gskill 2600 CL10 maybe samsung , i am not sure . Maybe is high-bin hynix

gskill 2666 CL11 it is hynix

Team group 2666 CL10 it is samsung

samsung is best choice . Cas latency is 10 .

[emertX]

Thanks a lot - due to some answers in the g.skill thread, there is samsung under the 2600's

then u can choose the brand u prefer ..

for ASRock Z77 OC Formula event here you can check ton of pictures from link below

http://www.facebook.com/media/set/?s...7573870&type=3

from event we have some good chip it can bench 3D easy at 6.6GHz but not enough time for
more tweak or try for other benching and for max post at event can show at 6.9xxGHz screen

Thanks for hard of work from you man

btw. can fix about Rapid OC for can select more Vcore limit ? it not enough for 1.7V, should be max

1. u have to enabled the extreme voltage in BIOS !

2. u have to set your own Vcore limit in the rapid OC software for some safty reason . please download from this link

http://picx.xfastest.com/nickshih/as...latool0830.rar

[ZoLKoRn]

1. Yes already enable

2. it limit only 1.7V for max select on Rapid OC Software and for Formula drive it can setting over 1.92V but Vcore won't go up it stuck at 1.92V on CPUZ

u have to choose the limit in the drop down option of vcore limit . i can choose to 2.1v here no problem !

And if u use the early P bios to bench , u cant change it for sure . Only the new L bios here and new P bios in the future will support 2.1v on rapid OC !

[ZoLKoRn]

OK i let checking it again later now it not on test bed, Thx for help

edit : Ahhh...Okay i see on event we still used old bios 1.13 it other board with on my hand so bad for not update or checking before

[nickshih]

OK i let checking it again later now it not on test bed, Thx for help

hopes we will bench together again soon !! see you

[ZoLKoRn]

Yah.. i hope so !!! see you too
