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

[boldenc]

That is the bios selection jumper which allows you to move from the primary bios to the secondary backup or default which came with the board originally, moving to 23 will allow boot in the backup bios then just shut down and move the jumper back to 12 and boot again at which it will ask to flash the primary bios to whatever you want by instant flash or internet flash or other source such as a thumb drive. Reboot again and your good to go with the new bios, backup bios can not be changed yet i believe like on Gig boards but that might change.

You sure about the shutdown and move the jumper back to 12?

What I did
- move the jumper to backup bios 23
- boot the system
- asrock logo showup then it redirects to a screen asking for the bios file
- if I shoutdown and move back the jumper to 12, it doesn't ask me to flash and it boots with the old bios

[flesheatinvirus]

I took that from the book though I never did that for changing my primary bios. I just loaded defaults then rebooted and used instant flash to jump to 1.60, have not tried the newer bios yet.

Hi, i've a problem with rapid oc. I can encrease the ratio but i can't encrease the BCLK.
I've install the INF file after rapid oc instal can be this the reason? or need some particular driver?

[nickshih]

Hi Nick,

can one put with the OC Formula Transmitter and Receiver Slew, how with the Asus Board?

Asus made up the name of that option . They have their own way to tweak dram overclocking . It is not common solution inside the bios.

I have improved the memory overclocking ability in my BIOS already .

Base on different way of tweaking . The same memory module is possible to have different overclocking ability on different mobo .

[nickshih]

there is random red led which appears after a restart, at the post checker behind the ATX 24
When I enter the bios, then exit, there is no red led, later restart windows and the red led is back. may I know what does this read led mean? nothing in the guide.

It shows the booting sequence of ur mobo .

If it stops at CPU led , it means cpu initial failed

If it stops at memory LED , means memory training failed

[nickshih]

anyone tried the bios select jumper method to reflash bios?
when I move the bios jumper from 12 to 23, it boots and instantly it shows the instant flash screen asking to plug a fat32 device. Do I need to move the bios jumper back to 12 while the system boots and showing the instant flash screen?

Move the jumer from 12 to 23 , It is backup rom to support instant flash function .

It will flash ur main bios rom . Please follow the instruction on the screen .

Put the bios rom file into ur USB ,then choose the file from ur USB device.

After flashing the bios , follow the instruction on the screen . It will ask you to move jumper from 23 to 12 .

After that .... reboot . Everything is done .

U need to install Intel MEI driver

http://www.asrock.com/MB/overview.as...20OC%20Formula

Intel Management Engine driver ver:8.0.10.1464

[nickshih]

Doubt it,ram is very poor on asrock oc formula,hate to say this but rog boards are far better.Cpu side si another story,here oc formula is very good

Seems that u got a defective mobo .

I found that someone has the same situation as yours .

After he changed another mobo , then everything is fine .

How to set the OC Formula IO L (CHA) and IO-L (CHB), if I, for example:

IO-L (CHA) 4
IO-L (CHB) 3

have?
I can set a maximum of IO-L (CHB) +1Clock, but then I have. 4/4, I can not at IO L (CHA) -1 Clock so I have 3/3,
that's not so Can this be said, the IO-L (CHA) & (CHB) tREFI dependent?

RTL will reference IO-L . If u modify the value of IO-L. RTL will change also .

So TREFI is more important . U can leave IO-L as auto .

Just write out a BIOS, what is working and if possible without memory profiles, which are good for nothing anyway.

Obviously you must have a bad board as this is easily one of the best memory clocking boards imho. I can clock my dimms fine with or without memory profiles, but I prefer to use them as it saves a little time over manually setting every secondary and tertiary.

My first one had a small issue with vdimm, and after a swift RMA the new board has been painless for me with PSC and BBSE

And keep in mind I have tested every top tier Z77 board minus the M Power from MSI.

[flesheatinvirus]

I agree my OC clocks ram very well and takes chips to the absolute limits with ease and I too have tested a load of boards, money is not an issue so my torture rack always has the very best. I currently have four liquid systems active in this room and this board build is the best one by far, in the last month nine different 3770K chips have passed through this board plus Gskill, Corsair, Teamgroup and Avexir ram all of which ran faster then there rated speeds rather easy on this board.

I did not say that the Maibord is bad and I had already some other motherboards including Asus and this is much better in terms of memory, all the same whether Hypers, BBSE, PSC.
On the OC formula, I have to max now 2 Kit BBSE 1225MHz CL9 ran 4 kit PSC 1225 CL8/1300 CL9, 2 Kit Hypers 1200CL8, 3 Hynix 1275 CL9 kit, 2 Kit Samsung.
Does not matter whether PSC BBSE or Hypers, the mainboard constantly spits 55 and I have experienced so far with no Z77 board. Except OC Formula and that has to do with BIOS.

Actually, for me, 55 on POST display on ANY 1155 BOARD is a timing or voltage issue, not anything else. Get 23, and you might as well forget it, but 55 can be dealt with.


I run 2750 Mhz with all DIMMs populated with 0.925 V VCCSA/IMC, and 1.05 VTT, no matter what board. Only one Z77 board has issues wit hthat, and that is the Gigabyte Z77X-UP7, where you need to use specific BIOS for whatever IC you use, at least, to get that memory scaling without increasing VTT or IMC/VCCSA.

I've been clocking ram on these boards the past two months(with about 5 more missing there):

I had the same thing with the MVE and vaseline after replacing the board all my issues were gone, do you have another sample to at least test with before you blame the bios?

I have been using P.160 with no issues at all and I have good samples of every ic (BBSE, PSC, Hynix, Samsung) and they all work flawlessly on the OC Formula, but PSC and BBSE really do fly on this one.

Test a new board before you blame the bios

Probly more Vdimm will help for 1300+ on rams regardless of board used.
Most of my "good" bbse/psc need 1.87~1.95Vdimm on air to finish 32m and less for other benches.

[flesheatinvirus]

Nice collection cadaveca, looks like this room.

Thanks!


Z77 has added so much to memory OC, I like it a lot. The OC-focused products from each brand are doing pretty good, but this ASRock is the one I had the least number of issues with, and I got mine rather early, too. Worst thing I could find about this board is that the yellow isn't the same colour on all the yellow bits and bobs. The BIOS wasn't as mature as it is now when I reviewed the board, but it has come a long long way.

I don't have many chips, and seemingly ones that do not like 2800 MHz or more, unfortunately, and no board has helped with that at all.


I'm done with Z77 now though. Didn't even keep me interested for a year.

You're all absolutely painless, from 1.87 to 1.95 V VDimm?
Then I will prefer not to 1300MHz, here are a couple results:

1200MHz CL9 1.78 V VDimm BBSE




1200MHz CL8 PSC 1,74V



1250MHz CL9 PSC 1,755V



1300MHz CL9 PSC 1,795V



Of course you can treat Post Code 55, the problem is that you have to flash with this mainboard, new BIOS.

[Alex-Ro]

It does not need a new bios,it needs a different memory vrm.It';s implementation it's ,other bbse or psc chips complete the 32M on other boards with 0.05 V less than this board,alsi the real voltage is 0.02 higher than what you see(a good friend tested extensively this board).It's a good board for CPU(Even if it's limited to 1.92V on ln2) but for memory it sucks badly.I am not going to start any fanboy war here,my sticks of samsung which performed flawless on maximus V gene,V formula and V extreme sucked so bad on this board.It's possible my board was broken,but it was then you better send me a new one for free cause i am not goind to start binning motherboards now,already tired of binning cpu's,ram,now mobo....?

I absolutely loved this board for it's CPU vrm,but memory is a crucial part too and this one it's unacceptable.

[Zeus]

I'll be honest. I was able to boot at 2933 with the Gene even though it wasn't stable, it did enter Windows. With the same ram in the Asrock it would not post at 2933. Apart from that this Asrock board was stable as a rock and i really liked it even though it took me some time to get used to the spacey UEFI, especially with the sound effects turned on.

Also at 3D marks this board really shines.

[nfszocker]

The board is not bad, I'm not the person to issue the same and get all the chips on the board up and running, is a fact that the board is not the high-flyer is the way it is made is,
as for memory performance, self cheapest Asus can more as this board and under 1.80 V.
Furthermore, I have now shot up even with no board windows, with this here already twice.

Seems that , u guys has some problem with memory OC .

I believe that it is pcb quality issue of production from Factory . Nothing related to the BIOS and Mobo design

I think you can just send the mobo back for RMA and replace a new one .It is the fastest way to solve this problem.

I know u guys want to compare with ASUS mobo . In fact , lots people also clock bad on M5g ,M5e etc.

Thanks for u guys's advice . I will try to improve the quality of production on Z87 OC formula . For better consistence of overclocking ability.



About the 2933 booting . I tighten the threshold of memory training for better memory verification .
