Posted March 2, 20178 yr ROG Crosshair VI series Disclamer: This is not an official support thread and tools/software is provided as is. Use at your own risk. BIOS 0083 0081 + "2T" DRAM mode 0082 0081 + specific DRAM patches 0081 0081 + ProcODT = 53.3 ohm 0079 New AGESA 1004a 1001 (DRAM 1T mode) Restore defaults before flashing, or use USB BIOS Flashback. 0038 (DRAM 2T mode) Same as 1001 but DRAM set to 2T mode, better on some systems. BIOS 0902 First BIOS with fixed "BIOS updating" problems. 1001 newer and recommended over this. 0090 Has some performance tweaks for Geekbench3, has BIOS updating bug on some boards.

March 2, 20178 yr Looks like fun,i love platforms that leave some performance and bugs to be found out with new bios or new findings .
March 2, 20178 yr Author Cheers guys, small update to the OC guide. Mostly a few error corrections but also added info on timer skewing and HPET.
March 2, 20178 yr Nice one! Finally there is some bus speed adjustment back, giving more headroom for perf. tweaking. nice!
March 2, 20178 yr Thank you for this elmor, hopefully I receive my R7 1700 + CH6 tomorrow when I Ryzen! .
March 3, 20178 yr Was going for X370 Prime Pro, but after seeing this, CH VI Hero is tempting me. Thanks for sharing!
March 3, 20178 yr Jon,can you put some info about cpu binning like what do good cpu's do and what bad do,is scaling linear like best on air = best on cold,are there any hard-walls ? Also CPU-NB appears to be linked to DRAM Clocks from what i see in screenshot,is it possible to adjust it independtly? Thanks

Thanks LOL 3.9 bad 4.1 good. you want to spend $329.00 USD at min to bin for a water/air chip to gain 100-200? $500 chip binning for ln2 will get expensive quick.

Also CPU-NB appears to be linked to DRAM Clocks from what i see in screenshot,is it possible to adjust it independtly? Thanks No strong correlation so far, all depends on scaling with temp/voltage as usual. Good air chip with good scaling is what's needed for a good LN2 chip. Fabric, IMC and DRAM all run at the same frequency and is not adjustable.
March 3, 20178 yr Thanks Jon, I made a good choice to get the Crosshair board again, but they wouldn't sell me a CPU before NDA lifts. Now it's national holidays and I have to wait until monday, but don't know which chip to get. It seems they all clock the same +/- 200MHz, but you probably have 4 - 4.1 pretty much guaranteed with 1800X. Anyone tested 1700 and 1700X under LN2? I know AMD wants to promote their flagship CPU, but not convinced it is worth it atm.

March 3, 20178 yr Author in download link is stll guidev03. Its only bad name of file? Snoozed for a bit there, updated now.
March 3, 20178 yr I read a lot of review and seems, Ryzen scaling with RAMs clock in games also solid I will try test to Superpi 32M vs RAM at locked 4 GHz CPU
March 3, 20178 yr Wasn't amd allways good in scaling with ram in coralation to perf. At least that was my understanding Verstuurd vanaf mijn MotoG3 met Tapatalk
