New Microcode to further enhance AMD Ryzen memory compatibility
AMD will be releasing a new AGESA microcode update this month, this is now being worked on by the motherboard manufacturers. The new microcode (which is located in your BIOS) will further enhance memory compatibility.
This news has reached us by way of Gigabyte. A technical marketing employee has been explaining that AGESA 1.0.0.6 for Ryzen processors will enhance memory compatibility with high clocked DIMMs and would open up 20 new memory registers.
Gigabyte employee: Wish I could drop in and give you guys a new BIOS but I don't have them yet. Latest word is they are working on a new set with AGESA 1006.
Just to recap these are the issue being worked on:
- For those looking for IOMMU fixes we are hopefully going to have an option to force boot off a specific PCIe slot. Its not the grouping fix, but a work around for now.
- Disable LAN (Per request)
- Disable Audio (Per request)
- "ROM Image update" (Being worked on with AMI, no ETA)
- Cold boot / Wont boot. Have to re-flash BIOS. (people have referred to this as "soft brick")
- AGESA 1006 - improve memory (Got high hopes for this one. Going to enable 20+ memory register)
That means there will be another 20 memory kits added and supported. AMD back in April already released AGESA 1.0.0.4a which brought slightly better performance, lower memory latency and also increased memory support as well as faster bootup (post) times.
As you can see AGESA 1006 is in the works and should see the light of day with initial Beta BIOS updates soon. Btw the Gigabyte employee mentions AGESA 1006 twice, he could actually mean 1005 as the last AGESA release from AMD was 1004a.

I might be wrong but perhaps Windows is reporting the base rate before it's doubled? (DDR = double data rate)

If you are using 2400MHz DDR4, and windows and/or CPU-z/or other monitoring program is showing 1200MHz, that is indeed correct.
1200MHz x 2 (DDR)= 2400MHz. Of course, if you are using 3000MHz RAM, it should be running at ~1500MHz to give you your rated speed.
My 2666MHz Gskill FlareX modules report @ 1333MHz for me. This is how DDR memory works, this is the same for Intel systems-- it is not an AM4 or Ryzen specific issue.
Agree about the responsiveness of the 1700. Paired with a decent SSD and AGESA 1004 BIOS update, my Win 10 Pro system boots in mere seconds, and once booted the system is extremely snappy-- I suspect having 16 threads helps tremendously with all the little background processes happening in Windows...
Ryzen is def. a game changer and an incredible value, AMD deserves good sales and some financial breathing room, the engineering of Ryzen was a valiant effort for such a small firm (compared to Chipzilla).

This is the new Agesa microcode big update that everyone it's waiting for and finally it's been worked on right now. New bioses are on the way and we can expect higher memory clocks with Hynix ics based memory as well as Micron , much better compatibility , more memory dividers ( hint ! DDR4-3600Mhz anyone

I'm sure you're right. The system is too fast to be otherwise. It just threw me off because the X99 chipset I upgraded from, actually reported the doubled speed. But that could have been the ASRock BIOS on the x99e-itx/ac mobo.
I will say I also love the AM4. It's a helluva lot quicker to slap on an AIO water cooler.

Much needed. Just upgraded yesterday to Ryzen 1700 from an i7 5820k @ 4GHz on water. At stock 3GHz entire system and all apps are noticeably more responsive. Rise of Tomb Raider @ 1440p high settings with HBAO+ the Ryzen was 61fps (+3fps), Gears Ultimate Ultra @1440p 70fps (+1fps) w/GTX 1070.
Got it OC'd to 4GHz but can't do "anything" with memory. HyperX Predator DDR4 3000 CL15 running at 2400MHz. Windows reporting at 1200MHz. Memory definitely needs a fix, but even with Memory dragging me down it's so much better than the 5820k it's ridiculous. There's something fishy with all these benchmarks, Ryzen performs fantastically and its still gimped. No wonder Intel is running TV commercials non-stop.
Kudos to guru3d for being one of the first tech sites to stop drinking the Kool-Aid and report on the true performance of Ryzen.
I got the 1700 on sale, and sold my 5820k for $250 online in an hour. I'm ready for Ryzen 2 and a better than Biostar (it's OK) mini-itx motherboard. I actually don't think I'll need to up the processor for some time if they can get my DIMMS running right.
It's my first AMD processor. I definitely no longer consider them second class. Looking forward to seeing if their new GPU can actually deliver equivalent value and performance.
