Latest beta bioses

• 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.
• 0902 First viable bios for C6H. Superseded by 1001 & 0038.

Great list, and thank you for posting it.

I'm curious about the 1001 bios though. I am running it and getting 2T with both stock/defaults as well as an overclocked profile matching another person's numbers exactly. Any thoughts?

1T/2T rule only applies at 2666 and above.

If 2DPC or using dual-rank sticks (All 16GB and some 8GB modules) you'll be in 2T mode at DRAM Ratio's below that on both bioses.

I filled it yesterday from another forum I think.

But for testing purposes I post it here too for the users to see:

CPU: R7 1700
RAM: G.Skill Trident Z RGB DDR4 3200 CL14 (14-14-14-14-34-1T)

RAM is stable and works at @ DDR4-3200 14-14-14-14-34/36-1T.
Performance:

-1T



-2T




RAM is stable and works at @ DDR4-3500 14-14-14-14-34/36-1T but gives problems to POST sometimes (F9---->0d)
Performance:



I hope this helps with the research and futue BIOS updates.

You're running pretty well there so not that useful for us to make improvements We're working with AMD to have a fix for issues during POST with high memory clocks.

That would be great. It's frustrating to have to reset my bios to defaults every morning when i turn my system on, to get it to post. Then apply my OC settings an hour later after the system has warmed up...

Great! Can you post your BIOS settings, please?

If I have two sets of F4-3200C16D-16GTZR for a total of 32GB, would that be the same as F4-3200C16Q-32GTZR ?

It is generally advised not to combine multiple kits - even the same make and model. The kit is tested at the rated density (of a single kit) only, so two kits together may not achieve the same speed. When you purchase a single high-density kit, you're paying extra for the fact there's more chance the kit will work as advertised.
