What ever happened to AGESA 1.0.0.5 that was supposed to release in May? Have seen nothing as of yet from Gigabyte...

Considering 1.0.0.6 was released in may, i'm not sure how that matters?
Companies skip version numbers all the time, generally for reasons we are not fully let known. But i'm just not sure i understand why it would matter...

Eerliest tests with beta BIOS versions by The Stilt are looking very good. New AGESA gives option to change most of the subtimings. Huge difference between 3200MHz vs 3200MHz LL (tightened timings).

Is it technically over clocked ram if the speed it's advertised at is what your going to be running it at though if say I bought a dimm that's advertised as DDR4-1333MHz and I run it at 1600MHz then that's would be over clocked but if a dimm I buy is advertised as 3200MHz and I'm going run it at 3200MHz how is that over clocked

Replied on that official AMD page for it but it's waiting for moderation. Fits to paste it here. Seems like it's working great!
"Already went from Crucial Ballistix Tactical 2666mhz 1.2v to 3200mhz 1.36 with good timings after updating to MSI Tomahawk B350 Arctic beta bios with this. Wasn't able to post at all with over 2666 before using any settings.
For 3333mhz now I would probably need to adjust some of these bios variables listed as it doesn't always post(5 memory tries per post) but when it does, passes all memory tests(even prime95 25min with memory test settings)."
It's manufacture overclocked. Default JEDEC is 1.2v for DDR4, all that are 1.35v and such are factory overclocked. Or at least considered such. So it's like stock OC on gfx cards. It's overclocked but not by you; and it's promised to work at that. Afaik, could be wrong too.
EDIT: That AMD source about AGESA with new bios parameters https://community.amd.com/community/gaming/blog/2017/05/25/community-update-4-lets-talk-dram

Hilbert glossed right over this brings DDR4-4000 support. That is pretty crazy by my calculations that should get 1080p gaming another 10-12% performance like going from 2133 to 3200 netted about 15% performance.

I assume that also depends on the timings, if you have to increase the timings to reach 4000MHZ the performance improvement will not be that big
Dygaza
Well as you can see from the chart I posted, timings actually do more difference (naturally effect varies between applications and games). But overall decent performance uplift just by updating bios which allows for proper memory timings.
If only these changes were possible when first reviews of Ryzen came out, most people would have very different opinnion of Ryzen's performance.

Those IOMMU changes basically made Ryzen the only affordable proper VM solution on the market.

The virtualization feature sounds pretty awesome if it works as intended 🤓.

AGESA 1.0.0.5 for Gigabyte x370 is out for 2 weeks now
http://forum.gigabyte.us/thread/886/am4-beta-bios-thread?page=55&scrollTo=4891
but it didn't get much publicity since it was only released as beta because of the fact that it fixed mainly the FMA instruction bug when running a specific type of benchmark. Standard workloads like gaming or productivity were unaffected.

Its not at all hard to understand-- nothing was released in May, at least from Gigabyte. 1.0.0.4a is still the latest BIOS rev for the Gigabyte gaming boards. That came out in mid-April.
Second, didnt AMD say 1.0.0.5 was slated for May and was for better memory compatibility and now they are talking 1.0.0.6-- unless I am mistaken and it was never called 1.0.0.5. In any case, I dont really care what they call it, but if they say they will release 5, never do and then release 6, then yeah, thats a bit strange...
jortego128
Ahh... I wasnt aware of that-- it was never released for their B350 Gaming series boards. Hopefully that is not the case with 1.0.0.6...

Very nice gains. Do you happen to know what the same test provides on intel? Just curious to see how much this closes the gap.
Prince Valiant
I only see the one chart in the original post.
Someone else posted Witcher 3 results a few posts down (60fps at 2133 to 76 at 3200). Looks like they mention the 7700K but no chart. I think they're saying Intel is still about 10 - 15FPS higher on the minimum?
Dygaza
Akselic is saying that before the difference was 10-15 fps for Intel, but now his Ryzen is only 5fps behind of his 5GHz 7700k with 4000MHz memory.
MorganX
Ryzen has done excellent during this teething period. It can only get better once the BIOS' and memory support matures. I think then we will see the Dell's of the world jump on board.
This is good.
Loophole35
If this is true, it's great news. Looking forward to possible re-reviewing of ryzen after all the micro code and memory issues are ironed out.

Elmor from Asus ( R&D ) just posted 2 new Bios based on the latest Agesa microcode 1.0.0.6.
Early Beta Bios for Asus CrossHair 6 x370 = 9943 and 9945 ( If Hynix AFR 4x16GB or Samsung B 4x8GB, you might have more luck with this ) , post #15903 on this thread at ocn from Elmor download here - http://www.overclock.net/t/1624603/rog-crosshair-vi-overclocking-thread/15900#post_26106654
New multipliers:
3066
3333
3466
3600
3733
3866
4000!
People are reporting great things on this very early beta bios , Hynix dual ranked memory now works at 3200Mhz as well as Micron memory on 2x16GB as well as 4x8GB populated dimms. People are getting DDR4-3733Mhz + on Samsung B-die memory without touching bclk 🙂 and i expect to see DDR4-4000Mhz soon ... , as they keep tweaking and improving this Bios before they are official at Asus website. Keep in mind these are very early beta bios and the first one to come out with the new Agesa microcode , so they still have a bug here and there to iron out. So sad i'm not at home to thoroughly test this bios 😏, but once i get home i shall test it for maximum Ram speeds.

That virtualization info sounds pretty slick, better access to faster RAM for the masses is very good news too.
