You can, but IMO, if your sticks are not doing XMP on this platform, then it most probably AMD, Mobo maker or your CPU IMC's fault.

Of course you don't have to keep it, but I don't think its the RAM manufacturer who missed the mark in the binning process. Just my 2 cents. smile.gif

Interesting, so how would a memory controller that is failing to manage 3200 on a mobo advertised as capable of 3200, be grounds for RMA'ing your chip?

How exactly do these memory controllers work?

I know the quality of silicon can cause electrons to "stray" off path into adjacent pathways causing instability-- and its these rogue electrons that make us unstable.
(To go on even further, the cooler something is; the better it conducts, therefore electrons stay on their pathways--hence LN2 / water cooling = better overclocking).

/\ /\ But thats all to do with the CPU cores. How Does a memory controller come into that? I'm just curious as to the science behind it? Is it part of the "main silicon"? I.E. if thats the case; surely a chip with a poor memory controller would also be a poor overclocker? (I.E. less likely to hit 4.0GHZ)?

I need you guy's advice. I have a MSI TomaHawk B350 board (Crosshair Hero 6 in for repair) and I'd like to know if this board could hold back my Overclocking. I have 2 Ryzen CPUs, the 1700 and 1700x that I have can only do 3.9Ghz at 1.42-1.44 volts, are they duds or could the board be at play here. I'm really looking to get 4Ghz. I might not get back my CrossHair hero board for another 2 weeks (sent for repair since March 26) as they currently have a shortage of boards -_-

Memory controller at end of the day is still part of the silicon & we know there are variance from chip to chip. As no 2 CPUs overclock the same, neither are 2 memory controller always the same. It just about how low the does the worse one swing. Intel is at a point with their Skl/Kbl architectures that even the worst of the worst IMC will still do 3733-3866. Good ones will do 4266+.

On AMD Ryzen, seems like the worse memory controllers are bad enough that they cannot even do 3200Mhz. CPU manufactures are smart & hence they don't specify memory speeds outside of safe zone, just as they don't specify overclocks that the user will be able to achieve. I haven't checked, but I think Intel specifies upto 2400Mhz on SKl/Kbl & so does AMD (Again these numbers can be off, but neither specify more than 2666 for sure). Anything above those speeds is considered "OC", aka there are no guarantees & they CAN, if they want to, deny you RMA on a chip that you consider has a bad IMC.

I think mobo makers can get off by saying that its the chips fault (weak IMC) unless you can prove that the same CPU does 3200mhz on other mobo. Again, these are how these things are setup legally (IANAL). But if you tried to RMA your CPU or Mobo due to not being able to hit a certain mem speed, they'd probably accept your RMA because they don't want an unhappy customer. But I think they can legally say no to you if they want to.

So my bracket for the Arctic Liquid Freezer 240 came in, but the stand off has a very short thread causing the backplate to not be snug fit with the mother board back frown.gif I have not installed the cooler yet, but I dont think the cooler with stick with the CPU given the loose backplate frown.gif Anybody came across something like this? Gonna try and find some washers I guess.

EDIT: X370 Taichi mobo.

Yea, I'm hoping that AMD can fix the ram problems with updates, but I am worried that this might be the case. Some people's CPU can overclock extremely well but are stuck at the lower end for memory. Mine cannot seem to reach 3.9Ghz stably unless I go 1.38v+. However, my SOC can do 3200mhz 14-14-14-34 at 0.97v. I intend to keep my CPU at 3.8Ghz, keep my Vcore below 1.3v, and go as high as possible with ram if they unlock higher speeds without increasing REFCLK/BCLK.

I have a Artic 120 and didn't have this issue, backplate is snug. Just get 1 nut on 1 corner, then 1 on the adjacent corner and you should be fine. It still had wiggle room once I put the stand offs in the bracket.

Thanks for replying! So the wiggle room with just the stand offs is fine? I will proceed with putting the cpu unit on then and hopefully it tightens things up.

Ya, There was a bit of play, but nothing crazy. Since the back plate has that insulation piece you'll be fine. Just gotta give the bracket some tough love, on 1 corner, just get the screw/knob on the threads barely so it stays on there, then do another corner the same way, and proceed around by tightening in a STAR pattern.
