Ryzen BIOS update --> much better

Thu Jul 26, 2018 5:36 am

Hello,

I recently upgraded my Crosshair VI / Ryzen 1700X from a relatively ancient BIOS to the latest version and was shocked by the improvement.
- RAM used to run at 2800/CAS16/CMD2T now can even run 3000/CAS16/CMD1T. This is the worst possible RAM for Ryzen: double rank, non-Samsung B. Left it at 2933/CMD1T for more stability.
- ECC support is now visible in the BIOS. There is a setting to enable/disable and a couple of other details (word length, RAM poisoning -- don't know what this is). I would now feel quite confident buying ECC unbuffered sticks.

It's a pity that RAM compatibility was not as good at launch. There was also a complete lack of information concerning ECC support. The platform matured considerably.

Yeah, if your BIOS was from pre-1.0.0.5 or so AGESA, then memory compatibility wasn't great. Glad you were able to get something out of the update.
I do not understand what I do. For what I want to do I do not do, but what I hate I do.

Definitely ANY Ryzen mobo needs 1.0.0.6+ AGESA bios; that's where I really noticed memory timings and stability improvements. Unfortunately, AMD did rush the release a little, but they were already a bit behind on when they really wanted to release the initial Ryzen. AMD might have felt they needed to get the revenue running, even if the mobos/bios were not A+ on release. All in all, I think they did good and the 1.0.0.6a bios were out for my Asrock mobo around mid July 2017. I didn't mind being a "test" user... it was a long wait for some good competition.

I have the Asus ROG Crosshair VI Hero also. I noticed the big improvement after I updated to BIOS 6201. I have the Corsair LPX 2x8GB (Part#: CMK16GX4M2B3000C15 ) could only run at 2666Mhz and higher timings. After the update it runs at the rated speed just fine of 3000Mhz and CAS16-17-17-35. I dont believe these sticks are Samsung B-dies either and they are double rank. Another BIOS improvement was the fan profiles and its ability to regulate properly.

Two Ryzen 5 1600 systems here. Home desktop is in an Asus ROG Strix X370-F and home vSphere is in an Asus Prime X370-Pro. The BIOS updates that came out for Ryzen 2000-series seem to have finally cured the very occasional stability woes of both boards. I think it's versions 4012 and 4011 for these two boards. Prior version (last of the 3000 series BIOSes) was pretty good but there was still a monthly or so hang/reboot. i was a little nervous that there might be a regression with the support for new procs but it seems to be smooth now. 13 months with the vSphere system and 7 months with the PC in current config.
Be careful on inserting this (or any G34 chip) into the socket. Once you pull that restraining lever, it is either a good install or a piece of silicon jewelry.
