AMD discusses upcoming ram settings in Ryzen

AGESA 1.0.0.6 officially adds 26 new parameters that can improve the compatibility and reliability of DRAM, especially for memory that does not follow the industry-standard JEDEC specifications (e.g. faster than 2667, manual overclocking, or XMP2 profiles).

A source of annoyance with current and potential buyers of Ryzen systems is the lack of configuration of ram settings, especially for more advanced users wanting to push ram further. The possible answer was known to be in the next AGESA update, and now we have details of what it offers. It is unclear if this will also help existing not-so-compatible ram to reach higher speeds also, either automatically or with manual tuning.

If you’re the kind of user that just needs (or loves!) virtualization every day, then AGESA 1.0.0.6-based firmware will be a blessing for you thanks to fresh support for PCI Express® Access Control Services (ACS). ACS primarily enables support for manual assignment of PCIe® graphics cards within logical containers called “IOMMU groups.”  The hardware resources of an IOMMU group can then be dedicated to a virtual machine.

Virtualisation users also get an update. I believe the above will help those wanting to do a "X gamers 1 CPU" style build themselves.

 We are now at the point where that testing can begin transitioning into release candidate and/or production BIOSes for you to download. Depending on the QA/testing practices of your motherboard vendor, full BIOSes based on this code could be available for your motherboard starting in mid to late June. Some customers may already be in luck, however, as there are motherboards—like my Gigabyte GA-AX370-Gaming5 and ASUS Crosshair VI—that already have public betas.

And we also have a when, mentioning mid to late June here. Some boards may have a beta bios already offering it, I note the above mentioned are high end boards. Those with lesser boards we will have to wait a bit longer for mobo manufacturers to get them ready.

pretty sure i have my ram at 2800mhz so far i think, but im using a beta bios, so i cant check(bios says 2800mhz)

People can and have run ram at 3200 and likely beyond, but the annoyance is that general compatibility isn't as good as where it is with Intel platforms yet. On my two Ryzen systems I've tried G.Skill 3333 and Corsair 3000 ram, and I've not managed to get either running above 2666 so far. Even 2666 was only attainable with AGESA 1.0.0.4. Launch day bios was only getting me to 2400.

my mate is running b-die 2666 with BCLK taking it up to ~3400 without the AGESA on his crosshair, will be interesting to see what the new bios can do.

yeah, i might have to research the ram more, and maybe return the kit i have

TBH that's not too surprising as one's D-die and the other's most likely Hynix. Would have expected 2800 or 2933 on the G.skill, but 2666 is close. 

 

Proper B-die isn't that much more expensive than binned lesser IC's (and in some cases even cheaper); I don't understand why this is really an issue. Pay $100 for a basic Hynix set that'll do 2400-2800 or spend $140 for a set that'll do 3200+. If anything it's the fault of misleading advertisement on the side of memory manufacturers confusing consumers into buying kits in between.

If building a system from nothing, certainly research and pick known compatible modules at whatever speed you're targeting. I was doing Ryzen on the cheap by reusing ram from existing systems. I had what I had. Also higher speed ram compatibility on Intel isn't 100% perfect either.

 

The G.Skill 3333 is actually an old Ripjaws 4 kit targeted at X99. It will boot at rated speed on most Intel systems, but I had difficulty stabilising it depending on the board. Dropping it to around 3000 and problems went away. It was too close to the limit at rated speed for most boards to handle.

I've had my vengeance LPX at 2997 since 1004 came in beta BIOS 0082 for the crosshair, which I feel is pretty good considering its a Hynix kit. Though I will be flashing to 9945 beta BIOS tonight just to see these new changes brought in with 1006.

 

On an evolving platform such as this the ability to flash beta BIOS' has been great  I've had everything at rated speeds since the beginning of April.

If they'd just give us access to tertiary timings, then it wouldn't be a problem to get Hynix IC's to 3200+. Part of the problem is, we cannot define the perimeters for multi-rank, or 2DPC configurations via tertiary timings due to the fact that the options themselves don't exist.

 

If we had access to tertiary timings, literally every kit would be "ryzen compatible" with a little tweaking.

This make the case for a "Twelve Gamers 1 CPU NOW WITH RYZEN", that much more compelling.

I love the new Beta Bios for the C6H. Finally able to get 3466 without pushing BLCK over 100 on all 4 sticks. 

[Jito463]

Anyone have the FTP site where Gigabyte stores their beta BIOSes?  I want to see if they've got one available for the K7.

[Doobeedoo]

Well nice, better support for it. Goodie. 

[TrueMegaManiac]

Noice. Really wanting to do a two-gamers style build with Ryzen and now that's possible... once Asrock adds this to the Killer board.

Well, to answer my own question, I found this forum post on the Gigabyte.us website.
