AMD RYZEN Builders Thread

Question:

If I can get hold of an AsRock X370 Taichi, should I return the Gigabyte GA-AX370-Gaming K7, or should I stick with the Gigabyte?
 
Good deal, My R7 1800x replacement shipped out today. So looks like I will be back up and running on Friday.Now hopefully one of my two boards actually posts if not both boards knock on wood.
 
I'm guessing motherboard manufacturers can't officially state support for CPUs that haven't officially been released yet.

I will not be surprised if AMD manages to screw this up as well.

But atleast as rock requires a bios upgrade. So I won't be surprised if others do too.

EDIT: this is interesting, when you enter the link for the first time you can see the updates, but if you refresh the page, it goes away. hehe

Do you know if it'll work at faster speeds in the future?
Let me grab my magic eight ball!

Seriously though, there seems to be some hard restrictions on ranks and amount of DIMMs with the Ryzen memory controller but things have already improved since release. My guess is that you'll get faster but only single-rank dual-DIMM will achieve the highest speeds.
 
BIOS flashback:
Download latest BIOS 1001 or better and name c6h.cap, place on USB drive formatted in FAT32. Insert into USB port labeled BIOS. Hold down BIOS button on back panel for 3 seconds until it starts blinking (does not require boot, only power to motherboard). If it stops blinking, the filename or something isn't correct. If it recognizes the file, it will proceed to blink until finished (takes some # of minutes).
THANK YOU IEC. I should get the C6H Friday afternoon.
 
Live with it for now and *hope* it gets solved with some BIOS update or buy some new RAM and *hope* that solves the problem. No guarantees either way..

I own the Corsair memory recommended by AMD and I still have the issue.

New memory t'ain't going to fix it.

I have faith that it'll be fixed up in the next month or six. 😛
 
Interesting. 1.55 beta already had SMT toggle in the UEFI. Is 1.6 the same as 1.55 beta? If so, that is disappointing.
That would be my guess. It's likely just a finalized version of 1.55.

EDIT: I think they removed it again. I am thinking about going back to 1.5.

I put my PC to sleep, and when it woke up Dr Debug was giving me code 30, which has something to do with the CPU or memory.

I just put the PC to sleep and woke it up, and again I see code 30.

It goes away with a reboot though.

If it didn't have any new DDR4 timing settings then it's just a finalization of 1.55 beta. Might have a few improvements in there, but until they start supporting more ratios per the new AGESA code I'm not going to bother flashing to anything new.

That's in May from AMD to mobo makers so June-ish for BIOS updates.
 
Huh, thought the new AGESA code shipped already? May was supposed to be when they started rolling out more microcode to improve compatibility with non-Samsung ICs . . .
 
Hey guys.
Those of you with G-Skill Trident Z RAM (F4-3200C16D-16GTZ, F4-3200C14D-16GTZ, F4-3400C1xD-16GTZ, F4-3600C1xD-16GTZ)
What are you doing to have the boards post with any speed other than 2133?
How are you assigning the settings? Manual everything at the UEFI? Ryzen master?

I finally decided to thinker a little with this ram, and it was frustrating.
Stuck at 2133...
The AB350 Pro was updated to UEFI P2.20, just released today. No difference in its hate for this ram after the new firmware...

In my ASRock AB350 pro (bios 1.43 and 1.44 both work) I just set it to 2933 cl 14,14,14,34 and rebooted, all is fine. using (I think) F4-3200C14D-16GTZ

Well I spent most of last night Googling.
I think this might the root of the problem:
RAM Ratio and timings are applied very early during POST before BIOS has control which might give problems when changing both REFCLK and DRAM Ratio, if you get problems because DRAM Ratio applies first use Retry button.

AMD has their own DRAM recovery mechanism that automatically lowers the DRAM Ratio and resets timings if DRAM training fails (F9 → 0d) during early POST). If you reset at this point you might get stuck at CF or 90 POST codes, manually reset again and the system should POST with the lower ratio and default timings. AMD CBS settings are also reset when this happens.
http://overclocking.guide/asus-rog-crosshair-vi-hero-extreme-overclocking-guide/#Known_issues

I think what might happen is that every once in a while, the ratio gets applied first and for a split second, the memory tries to run at a high frequency with low timings and hangs.

Also, who knows at what time during the POST process the higher memory voltage gets applied. It might be that the memory initially tries to run at 1.2V for a short while, until the 1.35V that most high performance kits require can be applied. This would explain why I have POST problems but the memory is stable once the system has booted. In that case, memory that is sufficiently stable at 1.2V to at least POST and let the BIOS take over would probably work normally.

The C6H has a DRAM boot voltages setting, no idea if the Prime Pro has it.

Are those Samsung b 1rx8 rams?

This is bloody confusing. I found a F4-3000c14d-gvk last night for like 70 dollars new 2x8gb. I think its 2Rx8 hynix rams, but I cannot be sure. Does anyone know?

Got them anyway as those were at prices and hope for the best. If cannot reach the rated speed I feel like I will be debating weather to sell it or wait for AMD to fix it. It should be fixed right?
 
Unfortunately yes, there's absolutely nothing indicating each model is dual or single rank unless they're physically inspected, someone posts a CPU-Z SPD display for the RAM, or the manufacturer themselves advises you such.

I was planning on getting the Gaming 3 from Gigabyte. It's memory QVL actually lists if the memory is single or dual rank. In some cases it even lists the chip manufacturer.

Even if you don't plan to get that particular board looking at the QVL might be helpful.
