嗨， 有人知道如何解鎖 UX 上的 bclk 嗎？我有很好的 BIOS 但是.. 沒有看到選項

 

Could you please share your UX BIOS thanks

Anyone tried the ASUS ROG STRIX B660-I GAMING ? 90MB19C0-M0EAY0

I have one of these and it unfortunately does not.  Neither does the ROG STRIX B660-A GAMING WIFI D4 which is what I was shipped first instead of the B660-I.  

I have also tested the ROG STRIX Z690-G GAMING WIFI and it does not work either. 

I have a B660-G on the way from Germany, however it's been stuck in the Netherlands for almost a week now.

here's bios a22 releases for unify-x for specific cpu steppings. first bios versions that support non-k cpu oc at least from my testing

C is for C0 stepping CPUs, H for H0 stepping

Hi all, first post in 12 years ;o Been a lurker.

I'm mostly interested in B660 with DDR4, so I tried a few things:

Motherboards:

1/ ASUS ROG STRIX B660-A GAMING WIFI D4

2/ ASUS PRIME B660-PLUS D4

3/ ASUS PRIME B660M-K D4

4/ ASRock B660M-HDV (also D4)

 

Tried all available BIOS versions, dug around through settings, but none had BCLK overclocking. I didn't physically inspect them, as I didn't know where / what to look for back then.

So I have a direct contact at ASRock whom I asked and they checked with their mobo people in Taiwan: There are no D4 boards (ever?) supporting BCLK overclocking. The board needs an external clockgen (the latter we all already knew).

Buildzoid's most recent video suggests that there are/were/could be D4 boards that had the external clockgen/ - So I'm not sure if ASRock and Bullzoid are at odds there.

Hello..
And it also happens in the B660?

The z690 from MSI and Aorus??

That MSI z690i, when you restart with the OC by BCLK, does it restart normally, or does it turn off, and then turn on again?

Thanks a lot  

[Birilio]

Yup bclk OC is bugged when you restart. OC failed -> bios -> restart OK. Try to enable GO2BIOS. It's working a bit better with it on for me. MSI is already working on it according to skullbringer.

[Birilio]

I would like to add the two first bios for the z690i unify aren't working, v111 and v122. Retail v124 bios isn't working either, only the modded v124 from skullbringer is bclk oc capable for H0 chips only.

I found Buildzoid's vid from a week ago on the ASUS TUF Gaming Z690-PLUS D4 (BIOS 0808).

It has a "Manual" option in the overclocking section, and unlocks BCLK OC.  Not sure what to make of that information. Would it allow for BCLK OC on D4?

Does this MB have an external clock generator?  If not, it's most likely showing the Manual option because he is using a 12600KF.  I imagine once you install a Non K CPU that option goes away like on the Z690-G Strix MB.  

[Allubz]

Ah, right. It goes on the internal clock regulator of the CPU. I forgot about that. Thanks

Same for UX.

[MrPils]

Any sign of bclk oc for C0 stepping on the Unify ITX? I was hoping something would crop up when the new bios was released, but that came out Friday and my Google-fu has turned up nothing. Maybe not looking in the right place, but couldn't even find much discussion about it at all...quite surprised.

Are you able to keep it and test it with future bios ? The mini itx.

Yes, I do plan on keeping it.

Picked up my Unify ITX last week - latest bios 126 has no support for non-K OC, at least on a C0 stepping 12400f.

@skullbringer @Birilio Apologies for the @ from a random, but have either of you seen any sign of a C0 stepping non-K OC bios for the ITX board?

sadly no, also don't have eta. but you can mod the microcode from ux a22tc into 126, same worked for h

That's a great tip, thanks. I've had a quick poke with mmtool and figured out how to extract the microcode (well it saved something anyway lol). As is usual when you help someone though, I'm afraid I need to bother you with a couple more questions if you happen to know and are able to answer?

First do you know if the mflash embedded in bios will flash a modified file or is there a version in the public domain that will that I need to find? The ITX doesn't have a flashback button so there's no hard flash option.

The second question is a bit trickier but you may be able to answer if you helped with the H0 step mod. There's 6 microcode's in the bios for various stepping CPUs (two duplicates for 0670 and 0672 I assume for AVX512 support). Does the listed order matter? I suspect it doesn't normally (or maybe ever) matter, however I wonder if the AVX512 support that was worked in may affect that? No worries if you don't know, I'm just a little hesitant to check myself without a flashback button ?

If/when I get this working I'll share here, your help is much appreciated - Thanks!

Went with 124 to avoid worries about the many microcodes included in 126. MFLASH in bios works fine, no issues - just remember to maintain the original uefi rom filename.

Here's a link to the folder on my google drive with the extracted CO stepping non-K OC microcode, correct version of mmtool and C0 stepping modded 124 bios: https://drive.google.com/drive/folders/1lci7Womgksah48LfIJ1BGa64d9HKI2W_?usp=sharing

Direct link to the patched 124 bios for bclk unlock on C0 stepping cpus only: https://drive.google.com/file/d/17COf-uosnqr57Fzd9g6Zc7R3ve9_4X9G/view?usp=sharing

Tested and working, though memory ratio support seems a bit shit. On 126 unmodded I was stabilised but not fully tweaked out at 6933mhz, I can't post using ratios above 6000mhz at 100bclk with the microcode modded 124 bios. As long as the actual headroom is still there the higher ratios are irrelevant now bclk works.

I have made a modded 126 but its untested - I won't be risking it unless I cant match memory oc with 126 unmodded on this bios.

Thanks @skullbringer 

 

EDIT - I flashed 126 I modded myself and bricked my board. I used the exact same modding procedure as I did with the working 124 linked above, so I don't think I screwed up but it still could be a me problem if anyone else has the balls to try (no flashback). 124 bios linked above works fine, but isn't as good as the 126 stock bios for memory clocking - TM5 stability over 6600 was very delicate and not reliable between boots. I probably should've flashed stock 124 first to get a comparison point, too late now.

I'd like to try it at 12100, but...
Which board can I run reliably?

It's nice to dream, isn't it?

12100 should all be H0 stepping I think, so for MSI the Unify-X with A22TH or the Unify ITX with the modded 124 bios posted by Birilio above.

For Asus on z690 the Extreme, Apex and Hero using bios 0811 or various beta's between 0072 and 0096 (some do some dont). Haven't tried anything newer or seen anyone posting on anything newer.

On B660 I think only the top two ATX and mATX ROG boards, the Strix B660-F and the Strix B660-G. Not sure which bios version, its in Der8auer's second video on YT.

 

Just bear in mind the microcode isn't the best for memory. On the Apex I managed 6180 1T c28 1.45v/1.41v/1.41v stable, nothing I did would get it fully stable higher but it could 3d mark up to 6400 or so with more volts. 6460 2T was stable and would 3dmark up to 6570 on a good boot same voltage. Unify ITX with 124 modded bios went about a hundred mhz higher than the Apex at the same voltage, but still behaved the same. Both boards wouldn't go any higher even with clear voltage and timing headroom that gave improvement when not using the unlock microcode. For example, the z690i Unify using 124 unmodded went 6933 2T stable easily using the same voltage set with trcd43, only change being microcode and MC voltage.
