So for someone that rarely upgrades. Replaced my 8800gtx last month (for a 1070) and I'm still rockin a i7 920. The question is Ryzen 1800x or TR 1950x

I use routing software (courier route planning) Photoshop/Lightroom and VR Elite Dangerous. Both are probably overkill now but to future proof as much as I can

Here's mine... even with the trial version, the mem can't be quite right?

Bugger sorry: Mem read: 68344 ; Mem write: 82664; Mem copy: 72733; Mem latency: 103.2ms.

L3 cache seems low too: Read: 323.65; write: 166.05; copy: 163.6

Not sure how to insert an image, as it clearly didn't work above!
 
Those numbers are very odd, especially the L3 cache.

What's also strange is the reported agesa version of 0.0.6.0 even though it shows the latest 0503 bios which states it contains agesa 1.0.0.3 patch 4.

I really have no idea why this'd be the case; haven't seen anything like it before. Tried the new 0603 BIOS - L3 cache numbers look better, but mem values are still very slow and the AGESA version is still 0.0.6.0

Got round to trying to get my memory to its rated 2800 today after being stuck at 2133 for a bit - got it all working fine with Ryzen Master in about 5 mins after having many woes with the auto Asus stuff over the last week.

I've built a low noise system on air only, so I don't think I've got a much headroom for heat and was a little sceptical about hitting the rated speed on the memory I went for (8x8GB Corsair Lpx 2800 c14 1.35v) as a couple of people advised it was going to be hard to get above 2666 on a X399-A Prime with 8 sticks.

But it was that kit or get 32GB 3200 4 stick kit at same price so I took the risk - as double the memory but slightly slower seemed like a good trade off, quite pleased its c14 too.

Makes me grin like an idiot when I use this PC, and I'd been worried TR would not match the dual Xeon I was replacing. If I'd gone Intel again, the cheapest route to this level of performance if buying new would have been to go dual Xeon Gold 6134 (8c16t, 3.2/3.7GHz Turbo, 25mb cache), but its £2K per cpu and the motherboards make TR boards look cheap!
 
It's a great platform. I can honestly say this is the best upgrade I've ever made/experienced.
 
It was how I understood the chip, I could have course have the wrong end of the stick, I though it was two channels per chip into the infinity fabric with intra chip communication done the Infinity fabric
 
Yes :) .

This is the same for all TR models. This is how quad channel is supported.

As I understand only way to have one memory controller to use dual channel would be to know which specific RAM slots are wired to which memory controller and occupying those with RAM.

I was hoping someone had got info/figured this out so I could implement the same. Currently I'm using a kit of F4-3200C14D-16GTZ, hoping to buy another after the bank account has recovered from recent purchases :o .

I reckon Quad channel is probably the best setup when aiming to use all threads on a TR.
 
I would have thought the way the manual tells you to install sticks would be to the appropriate slots for dual channel certainly seemed fine for me on the MSI board using the outer slots on either side of the CPU, machine fired up said dual channel and had reasonably low latency and over 50k read/write bandwidth on Aida. I would have had quad but 2 of my sticks didn't work.

Tried everything I can think of, and can't get higher than: Mem read: 68344 ; Mem write: 82664; Mem copy: 69897; Mem latency: 103.2ms.

Yes I am using either side of CPU and as manual guides on ZE, but it does not allude to which memory controller I am using.

I would assume it would guide a user to use 1 channel from each memory controller, regardless of dual or quad channel, as this would be more optimal for all thread/CPU node usage.

I have slots as below and CPU in center.

D1, D2, C1, C2 < CPU > A2, A1, B2, B1

Now I populate C1 and A1 as guided by manual, I believe I am using 1 channel from each memory controller, resulting in dual channel. I would assume if I used A1 and B1 I would also have dual channel and there are other iterations IMO.

To do quad channel I would use D1, C1, A1 and B1. Thus a channel from each memory controller. This still does not allude which slot is which memory controller.

It maybe UEFI/AGESA does not allow us to populate RAM in the way to use just one memory controller for dual channel. I will try moving around RAM slots as soon as I can :) .

Strange behaviour, Normally read and write bandwidth are quite close, not sure what to suggest, is all your RAM working properly, I had an issue with mine where with 4 sticks in the bios could see them as in read SPD etc, but would report less ram than I have, and sure enough I would get into windows and it would tell me I have 32Gb but report half as it as reserved. Messing about with it I discovered that my machine wouldn't boot with two of the sticks, something is up with them, despite things looking fine.

It looks like you have a couple of issues, some RAM and the microcode update, try setting the machine to BIOS defaults and running with just the one stick of RAM, in this default state, try a reflash of the BIOS, see if it will take the microcode? Perhaps clutching at straws here but it's not going to hurt beyond time.

Then perhaps test bandwidth in single, dual and quad and see if the numbers chnage in the expected fashion.

Cheers for the help - I'm just about ready to try anything! All the RAM seems to be working ok, as is; just slowly. Windows shows 32Gb with 31.9GB usable.

Disable GearDown Mode so odd CL is not rounded to 16.

Other than that suggestion I reckon you gotta tweak timings/higher MHz for gains.
