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

[nickshih]

is there any way to solder up a "slow-mode" switch like on MVF/MVE ("LN2" switch on UP7) ???
this is the one feature that i use a lot on the z77 ROG boards that is not on this board. Any ideas?

i dont have it on Z77 . Z87 will have it for sure

[AMD LOving man]

it looks like u are failed on bios updating to 1.6

U can try to update again by the bios jumper close by the bios rom .

Follow the instruction on the screen step by step

Thanks for the help and the advice. Appears the problem was not with the 1.6 UEFI, but it is totally my fault. I got the same problem with 1.42L, but I managed to isolate it. Appears my CPU is not tolerating high VTT, PCH and PCH DMI voltages. If I push them around 1.3V I get the booting problems. I was trying to raise them to stabilize the CPU 4.7@1.395 but appears the CPU simply needed more voltage for this frequency. It can not go lower than 4.7@1.41 for Prime95 stability.
But lesson learned, now its time to fry the GPU

hey nick,how is the imc on hasswel?What memory is best for it,samsung or hynix ?

[kagula323]

Playing with samsung

verry nice Dumo! can you try and post also the voltages you use when taking this kind of screens? it would be helpfull for others too

testing another 2133 8-9-8 kit 1.88v

First off, loving this board for the most part. It was solid on subzero and efficiency looks good, but I have one issue.

Is there anything I'm missing for getting PSC to boot at 2600, with bclk or with the 26x multi? Either just gives me 55 postcode error. Tested back on my MVF and everything is fine, same standard PSC profile timings, 2600 and boot @ 1.82v. No IMC voltage changes. But it's just not working on the formula.

I can boot in on the 2400 multi and bclk up to 2600 once in windows and it will pass 8m no problems (didn't bother running 32m) so it should be able to post with those settings I would have thought. 1.60 bios. Any help appreciated, really need PSC working on the 2600 multi for some 32m runs I have planned.

Thanks.

P.S: Samsung works just fine on Z77-OC, 2666+ no problems.

have you tried setting timings and booting at 2400 divider, then restarting back into bios and just bumping mem divider up to 2600?

Thanks for the suggestion Splave, just tried that now and got the same 55 post code after bumping up to 2600.

TRY higher vtt & vcssa!

Good to hear no more issues God bless ur GPU ..

Hey buddy, i have NDA about anything on Haswell . But on OC formula , everything will be fine . I think it is clear

Thanks for the suggestion Splave, just tried that now and got the same 55 post code after bumping up to 2600.

Can u try higher Vtt2 ? what sub timing u used ?

Bcz different mobo the bios is not the same

[Dumo]

got the same 55 post code after bumping up to 2600.

I set psc tight settings, mem perf 2 @ 2600-1.925V/ccsa 1.247/vtt ddr 0.834 in bios then change tertiaries in windows.

Hope it helps.

Hmm, no issues with 2600 divider here, nor getting to 2600 with bclk, but as Splave posted go ahead and try booting with 2400 divider then reboot and try the 2600 that should work with no issues.

I actually tested a few kits of the same Crucial Ballistix PSC kit you have and they could all boot at 2608 8-12-8-28 but not always pass 32M with super tight secondary and tertiary timings even with 1.86v, but then again this was on air.

2800 c11 XMP is not working for me, however probably just IMC.

[jjjc_93]

Thanks for the help guys, same story though. Tried different vccio and vtt voltages, booting with the 2400 multi then trying to go to 2600 straight after, manually setting loose tertiaries, leaving tertiaries on auto, using the PSC profiles. Nothing seems to work, the board doesn't even seem to be trying to boot, just instant 55 error code. I'll try flashing the bios again and seeing if that helps, but I'm not too hopeful at this point. Tried multiple PSC kits that are all able to do 2600 on my MVF.

[Splave]

long shot but can you try loosening the motherboard PWM cooler a couple turns, also try reseating CPU

[jjjc_93]

Just got it working now, looks like it was a bios issue. Flashed back to 1.42g and 2600 was as easy as it is on my MVF. 1.82v, 9-12-9, 2600 divider and it boots no problems. No IMC voltage adjustments or anything.



Thanks again to everybody who posted and helped.

[emertX]

Yep...that's what I found out!
1.42G is the better BIOS!

[l0ud_sil3nc3]

1.42G is the better BIOS!

In what aspect?

1.6 seems ok but I will retest 1.42G tomorrow and see if anything changes

[emertX]

Yep! Do that!
I pretty sure, that it's the better bios for ram and cpu voltage!

[nickshih]

1.42g and 1.42k are with different training rules

Let me know which bios u guys prefer .. P1.6 same as 1.42k

[Dumo]

1.42K works awesome with cross section of ram chips

[emertX]

I prefer 1.42g!
But right now, I didn't test it under ln2!

Nickshih , i sent you the reply in a PM bro thank you.

Kind Regards: Angelo.
