AMD RYZEN Builders Thread

What do you mean: AMD's memory controllers "really" like dual-rank DIMMs..? Can you explain..?

Certainly.

More ranks = more performance @ identical frequency and timings.

For older Kaveri APUs the difference can be quite dramatic:

It means if you have dual-rank DIMMS at DDR4-2666 vs single-rank DIMMs at the same speed/timings, you get more performance from the dual-rank DIMMs. But it's tricky getting dual-rank DIMMs to run at high clockspeeds. A few have gotten DDR4-3200 with dual-rank 2x16GB DIMMs, but that list of people is rather small.

What DrMrLordX said. More ranks equal more parallelism, kind of like SSD channels. The more the better.

Thanks for the replies guys. I've been leaning towards the Taichi or Gigabyte (seems like most of what I have in the past 5 years is either asrock or gigabyte), price has me shying away from the Asus CH6. Ram wise I'm debating between getting RGB for the lulz or not. Not sure I want to pay the price for those. Either way it has to be stuff that can run at 3200 or better.

I have the Taichi and the K7 currently. The Taichi is a much better board. The K7 won't even boot into Ubuntu. Can't say that I'm surprised really. There is always some catch when I try a gigabyte. Probably return it and get another ASrock.

Sigh...

I know what dual rank memory is. I wanted to know why he put such emphasis on AM4 and dual rank. The review he linked is 2 years old. Ryzen is a different chip, so I was asking for the reason in which he states Ryzen really loves dual rank.

Secondly, if you populate 4 DIMMS, the benefits of dual rank doesn't matter, right? (technically)

 

[hotstocks]

Of course I looked for other power plan options. In all of them the CPU option % is just gone. Maybe because I am overclocked to 4ghz it doesn't show because it doesn't matter, the cpu is always at 4ghz on all 8 cores.

I think we're talking past each other. I stated AMDs memory controllers generally really like dual rank DIMMs. Not Ryzen in particular.

4x dual rank should give a bit more performance then 4x single rank, all other thing equal.

 

[HumblePie]

Not really. This is the second time he's hooked me up. Hoping a vega card comes through to play with. If not, oh well. What he already gave me was nice enough.

Friend is back with a couple of surprises for me. Unfortunately I can not disclose said surprises at this time. I will just say they are going to be fun surprises for me.

There's a review or two around here somewhere showing game performance with R7 using DDR4-2666 single rank, DDR4-2666 dual rank, and DDR4-3200 single rank. In the end the 3200 wins, but not by all that much. Hypothetically the best performance would be DDR4-3200 dual rank. But that's hard to do, for now.

 

[HumblePie]

Vega? Lol

I was being silly but maybe

Hmm, not good to hear. Thanks for the info.

I would avoid the Gigabyte K7 for now. On the F3 BIOS with tweaking overclocks I received a "ROM image not found" error and then my OCs would no longer apply. The only way to resolve this error is to reflash the F2 BIOS, flash back to the F3 BIOS, and then reset your settings. At the rate that BIOS corruption appears to happen on these boards, you will likely need the dual BIOS...

I am actually considering returning the K7 for a refund as I consider it to be considerably less mature BIOS-wise versus my ASRock and MSI boards. In the interest of fairness I may see if I can load the latest beta BIOS first to see if they've made any recent progress.

Don't know if this was posted before, but apparently, DRAM Boot Voltage being stuck at 1.2V is a bug:
http://www.overclock.net/t/1624603/rog-crosshair-vi-overclocking-thread/9700#post_26020881

Once this gets fixed, it should enhance memory compatibility significantly, especially with boards that lack a separate option for DRAM Boot Voltage (such as the Asus Prime and Gigabyte Gaming 5). Most high performance RAM is obviously designed for 1.35V, so trying to boot it at 1.2V is what causes a lot of the cold boot/reboot problems people are having.

Some reviews looked at DR vs. SR. Browse to the tables here:

I'm getting the same issue of "Rom Image not found" on my Gigabyte motherboard. Gigabyte is able to reproduce the issue and is working on a fix now: http://forum.gigabyte.us/thread/952/aorus-ax370-gaming-update-denied?page=2

Man it looks like ram was finalized extremely late in the process ! This product was rushed to the market.
We dont know where this stuff end but one have to wonder if may agesa is just a stepstone. A cpu that gets 1% faster each month just by biosupdates. Crazy stuff.

Was all excited when my 1070s came in today, until I realized I don't have an SLI bridge (needs to be one of those fancy new high bandwidth ones, too) and the cards don't include one.

Your motherboard didn't come with one?

Ah, that's better. Guess I'll hold onto the board and wait for further updates.

 

[Crono]

Wow, I'm dumb, yes it did. That didn't occur to me for some reason, even though I'm sure I saw it when I first opened the box. Thanks, you saved me $33. Installed, AMD + Nvidia harmony:

EDIT: Looks like it's working

 

[Agent-47]

Kinda got scared shitless today ,

Boot up PC , hello Bios prompt i never see because normally you boot straight into windows..
5min later , hello Bios prompt still being there
...eum reboot
Hello bios prompt again
5min later , black screen , still responding but very slowly to numlock on/off ok so not stuck
7min later tap delete
10min later ow bios interface , working normally

eeeeeeeeeum save and quit

Rebooting followed by instant windows loading screen ........

WTH.....


Spec:
No OC
AB350-Gaming 3 Gigabyte , default bios settings + SVM(virtualization) turned on , Bios F5
Saphhire nitro RX 470
16GB ADATA XPG

I also have a similar issue. If I activate raid and turn off serial/parallel com in the bios, I get a 10 sec long post on the RAID welcome page. If I press Ctrl+R to try and enter RAID, nothing happens.

Funny times we are dealing with, not that it has not been exciting.

The Asus Prime X370-Pro is $109 at Microcenter right now. In-store only though.

I was pricing out an R7 1700 plus a Taichi mobo and there is still a $50 off combo at my local Microcenter (Boston). Well, local as in a 50+ miles drive

Well that is a pretty good price for that board just be aware that board RAM support is pretty dismal at this point in time. Pretty much want to make sure you get Samsung b die single rank if you want to be certain of running higher clocked ram.

 

[guskline]

Just finished my second Ryzen build last night. My first is listed in my sig below.
The second is based upon the Asus Prime B350 Plus mb I got at Micro Center last month which was used with my 1800x until I could snag an Asus C6H which I now have as per below.

My son-in-law and daughter have computers I have built them in the past and they do some limited web design. My daughters computer uses some old parts including an AMD X4 cpu so it was time to get her updated.

The new build for them uses the Asus Prime B350 Plus mb, Ryzen 1600x cpu, 2x8G Gskill DDR4-3200 ram which at present is running at 2133, a EVGA GTX1050TI SC video card (4G), Corsair H110i GT AIO cooler, Crucial 240g ssd for boot and win 10 Pro OS coupled with a WD Blue 1TB HDD for storage, an EVGA Gold SuperNova 550W PSU all housed in a Fractal Define S windowless case.

I must say it is a smooth running rig. I hooked it up to my one 2560x1440 monitor just to get it installed and the GTX1050TI gpu was fine. Not a high end gaming gpu but perfectly fine for what they will need. The Ryzen 1600x stock really has some chops. Cinebench15 MC score was 1205 and Aida64 Queen cpu score was 66900.

They do a bit of work with blender etc so the extra cores should really help.

Really impressed with the 1600x cpu.

I have the K7 and arch, the booting issue on ubuntu/mint is due to the iommu handling in the K7, but since my last board was a gigabyte with iommu problems I made sure I used the boot command iommu=soft , and everything works buuut, i've heard it's ubunut/mint specific from the kernel they were using.
