Interesting it’s not such a big of a difference like it is with DDR3, that voltage difference would make it well worth-while too
Haha I was just checking biostar’s URL for the bios updates and found a new unreleased BIOS for our board. It was built yesterday.
https://www.biostar.com.tw/upload/Bios/X37AG919.BST is the link
Edit: I haven’t used it yet and wanted to tag you @ket
Time to re-redo our edits now 
Nope, turns out I’m an idiot. It’s actually last years BIOS. 19/09/ 2 0 1 7 
@ket @Lost_N_BIOS sorry for the false alarm guys.
lol yep I was about to say thats an ancient firmware 
@barisuraz I’ve finished the UI heres some images for compare;
The firmware is going to be passed back to Lost for any further driver updates and then we can all start looking at how to unlock specific CBS options, if you haven’t already been looking in to that that is in which case tell us what you know 
That looks nice, seems like asrock cbs is indeed more compatible with our board so I’ll stick to transplanting it.
@barisuraz alright once Lost has updated any other drivers that need it I’ll shoot a link your way for the CBS changes. I’ve got some ideas which I will be trying as well using the Biostar CBS. Once a solution is found to unlock individual CBS options the sights will then be set on the biggest issue of all; memory compatibility.
Look at that smiley in default boot logo!!! Who approved that on the graphic team? 
Images look great, good work and I know it’s draining editing all those headers! I especially like what you’ve redone in the actual BIOS UI, if they don’t like some of the changes, hopefully they would at least consider those for the main BIOS GUI
@ket I would ask you how to unlock CBS options, so you’ll have to advise me, then I can advise you back If I had board/CPU I could work on that, but it’s all Intel or AM3 over here Tell your Biostar contact to send me a test sample, along with cheapest ES AM4 CPU, then I can help 
Did you try change Suppress if hex string value to FF where I mentioned?
@Lost_N_BIOS I added the smilies to the default images as a way to express how unimpressed I am with the intern amateur hour designs lol.
Ahhhhhhhhhhhhhhhhhhhhhhh!! I thought they did that, too funny you did it to show how unimpressive it was 
I didn’t see the smaller ones until now
@barisuraz Can you give me the make and model number of the RAM you have been fighting with along with a screenshot of Ryzen Timing Checker showing your current memory settings? I might be able to do something to make them more friendly in the modified firmware being worked on and I can pass the information on to my Biostar contact.
RTC: http://i64.tinypic.com/ixqh4p.png
Memory model: Team Group TEAMGROUP-UD4-3000
After 20 or so days of trial and error to make it work without mem errors, I found out I needed to raise the voltages significantly. Ram chips usually start to spit out errors after 52 Celcius degrees and the raised voltages cause them to eventually reach that temperature while continuously memtesting. I put a fan near the modules and the temp factor was eliminated. The subtimings are from The Stilt’s Hynix MFR Safe timings. Extra settings that had to be applied are as follows:
Memory interleaving size: 2MB
Memory interleaving: Channel
Channel interleaving hash: Enabled
Memory Clear: Disabled
I had to raise many of the voltages in the ONE section to red values. DRAM voltage for instance is 1.46v. Also the board has booting issues when the RAM is overclocked. It takes nearly 15 seconds to post. Ryzen Master can’t read anything related to the RAM and RTC also reports CAD bus settings wrong. I’d be grateful if you could pass these to your contact at Biostar.
@ket
@barisuraz thanks I’ll look in to it and give the info to my contacts. Theres no way you should need almost 1.5v for that kit. I’d recommend experimenting with CLKDrvStr, AddrCmdDrvStr, CsOdtDrvStr, and CKEDrvStr ohm settings as these make a significant difference for memory stability the right value for those settings can lead to not having to increase memory voltage at all. I’ll send you an internal build of the GT7 firmware thats being worked on that has these options exposed in the AMD CBS.
EDIT Forgot to mention Ryzen DRAM Calculator you would also likely find extremely helpful in tuning your memory kit.
Those are enabled in my modded CBS but they don’t do anything useful in my case. Tried lots of different combinations but still needed +0.252v for the max stability.
@barisuraz are they enabled through editing the Biostar CBS module or by replacing the Biostar CBS module with one from another manufacturer? If it is the latter then that could explain why those settings are not having any real effect for you. Be sure to grab Ryzen DRAM Caclulator as well if you aren’t using it already.
They were transplanted. I used DRAM Calc for some of the timings it’s a pretty good program. Are Precision Boost Overdrive settings enabled on the insider build? Also wonder if we could change our SKU to X470 for the sh*ts and giggles
@ket
@barisuraz I haven’t looked but if PB isn’t enabled should only take a few mins for me to enable it. I replied to your query about changing SKUs in the other thread
