@Dan111baSh - Great to hear it, thanks for quick report back! So, all settings you wanted now visible too, correct?

Please don't send PM's for help on BIOS edits, I can't help with BIOS in PM's. Please make a thread and I will try to help as soon as I can - thanks!
If you appreciate my efforts and are willing to donate to help improve my hardware, gift cards work for me (Amazn, NuEgg, eBa) - send me a PM

hey @Lost_N_BIOS :) im back again with a short question.
is it possible to change the RAM ratio / multiplier via Biosmod? In the Asus Uefi i just can run 3466 or 3600mhz, but i want to try 3500/3533mhz with my bad Hynix AFR chips

@filip1404 - So, you need coffee mod BIOS? If yes, do you have a flash programmer, like CH341A? If not, order one now and wait for it to arrive.

@Dan111baSh - Enable Dram Odd Ratio, and or choose BCLK Frequency : DRAM Frequency Ratio 100 or 133 then you can x-multi 01-28h = below is max
100 x 28h (40) = 4000
133 x 28h (40) = 5320

In your target area mentioned, once you enable Dram Odd Ratio and or choose 100/133, you will be able to choose one of the below speeds. There is no way to do 3533
100 x 23h (35) = 3500
133 x 1Bh (27) = 3591

Please don't send PM's for help on BIOS edits, I can't help with BIOS in PM's. Please make a thread and I will try to help as soon as I can - thanks!

unfortunately no. no matter if I activate odd ratio or not.
i made 2 screenshots:
1st: 100:100; 2nd: 100:133 (both with odd ratio on)

is there an other way? maybe change the "ratio table" in the Biosfile? @Lost_N_BIOS

"IF" BCLK Frequency : DRAM Frequency Ratio = Auto, then what I mentioned (The largest list of multipliers) is hidden from you - Was this auto in your first screenshot?
If yes, how was 4000Mhz shown? Maybe this is going by DDR and not DDRx2, so 8000Mhz max if using... Na, can't be, no tables end in 14h to equal 4000 as highest option ** See continued though below
"IF" DRAM Odd Ratio Mode = Disabled, then what I mentioned (The largest list of multipliers) is hidden from you.

** I think maybe this is case, last set is 0xE = 14.... Hmm, not sure still. I need to see more images!
Please show me Max multi with 100 and 133 BOTH with Odd enabled and disabled, so 4 images, 2 each 100 odd yes/no and 133 odd yes/no
OK, sorry, all this reply will be a jumbled mess, I edited above and below after already typing it all out, and added this middle part here towards the end. I need to see these images before I can be sure what is going on here
And really, all of this is possible, in some combination, to use the highest multipliers, this isn't something that generally required a BIOS edit to use the multi you want, you just have to pick the correct combo to end at the multiplier/speed you want
Sometimes that means odd enabled, ratio auto - so look at it that way in BIOS too.

The first image you showed, had the first list here visible (ie top ram speed 4000 via 28h (40) x 100
Dram Odd ratio would be enabled by default, thus first set is visible to you by default, while dram odd enabled + Bclk/Dram = auto

Yes, looking this over now as I reply, maybe, I need to Null first Suppress If - QuestionId: 0x2955 equals value 0x0, so you can change this (Bclk/Dram) to 100/133 and still have dram odd enabled or in auto (0/1).
What BIOS are you using now, the biosregm.bin I sent you on 7/16? If yes, let me know and I will make this change.

See in spoiler below, the suppress if before each set of multi's refers to QuestionID of items above the memory multi list, so you can see what it's talking about/suppressing because of, hopefully you can see how this works
This is tricky to sort, because of how many lists there is, we can't unsupress them all because you ideally only want one (the largest). So, if above does not work how I think it will, then we can just take this first set, and null out all the suppress if's
Then change the other smaller sets to be suppressed no matter what, by changing their suppress if's into being suppressed by some other items questionID that is always true or always false etc (ie something you never change from default, tell me, and we change the ID's and values to that, so it's suppressed due to this)
Sorry, hard to explain that last part, hope you get what I mean, or maybe we wont even need to go there anyway

first of all, thank you @Lost_N_BIOS for your detailed reply.
Unfortunately i have to admit that the half of your text is beyond my technical understanding. :D

Im still on your modded Bios from 7/16 & it works perfekt, thanks again.

Here are the required screenshots:

100:100 odd off

100:100 odd on

100:133 odd off

100:133 off on

if I understand you correctly, you want to change some of the lower sets (like ddr4 800, ddr4 933 or ddr4 1066) with the matching ratio for ddr4 35XX mhz, right? :S

@Dan111baSh - Thanks for the images. It would be great if I could see the settings above timings, while the max is also shown.
Can you please redo them, so this is visible instead of the dropout pulled up? Sorry, I did not think to mention this before
Also, can you please add an image for BCLK Frequency : DRAM Frequency Ratio set to Auto + DRAM Odd Ratio Mode disabled = What is max memory speed then too.
Leave all images above when you add all these new ones, thanks.

Do you have XMP enabled, or AI Tuner set to XMP? If yes, disable that, set to manual, this may be messing with things, not sure.

It's OK about the stuff being too technical, it messes with my mind sometimes too As you can see above

No, I considered making only one set of multiples available for you always. All speeds, either way, are available to you without mod, but you have to have correct other settings applied before they're visible.
The longest list, with the most multiplier/speed choices (First one in spoiler above) should be visible to you if you have Bclk/Dram set to 100 or 133 manually AND Odd enabled manually.

okay, i am reassured @Lost_N_BIOS

here are your new screenshots in the same order with highest Freq selected
100:100 off

100:100 on

100:133 off

100:133 on

@Dan111baSh - Sorry for delays, always buried!
Can you please add one more image, so I have a total overview of some of this >> BCLK Frequency : DRAM Frequency Ratio set to Auto + DRAM Odd Ratio Mode Enabled

Notes to self for later
100 = max 3200 no matter what (So you never want/need to use this)
133 = max 4266 no matter what - 3466/3733 w/ Odd Disabled / 3466/3600 w/ Odd Enabled
CPU/DRAM Auto + Odd Disable = 4266
