One question that popped into my head is whether the hard limit around 3000mhz seen in larger RAM configurations is related to memory amount or number of DIMMs used.

I'm thinking it is the second one. The only way to test this would be running, for example, both 16gb x 4 at 3200mhz, and then trying 8gb x 8 at 3200mhz. I can confirm the first configuration worked, and the second gave me trouble, but unfortunately, memory type differed so we can't isolate the cause. I ran 16gb x 4 at 3200mhz with Samsung B, and failed 8gb x 8 with Hynix.

If anyone out there collects Samsung B, and has a variety of DIMM densities lying around, it would be an interesting exercise. We could also figure this out by crowd-sourcing a bunch of us who have Samsung kits of various densities.

But back to Ivanov's case, you might also take a look at a 16gb x 2 configuration to get your 32gb.

Surprised by the negative reviews on Newegg. At least as part of a larger kit, 16gb sticks gave me no trouble at all. Could be Samsung vs. Hynix issue. Some of the crosstalk in the Newegg reviews supports my theory on the X399-specific memory that Gskill started selling - the kits ending in X. I think it just Samsung B die memory binned one speed category slower than it can actually run, to ensure plug and play with Ryzen.


Man the 2x16 GB kit is 100$ cheaper than the 4x8GB. I already ordered the 4x8GB to be able to utilize the quad channel setup but the other one is a lot cheaper. it will realistically cost me 280$ more for the extra 32GB if i buy 4 sticks of the 16GB one. I'll have to think on that one. As of right now i have the 4x8GB kit on the way that i will have 30 days to exchange/replace. If it is running good i will consider it

Ah, never mind. No Ivanov, you did well buying what you did. My mind is locked in 128gb land, and I simply forgot that 4 sticks would allow you to take advantage of quad channel. Yes, indeed, setting aside the stability issue, 4 sticks is a MUCH more sensible buy for you than 2 sticks. It only becomes a factor if one of the configs isn't stable.

Right but the 2x16GB kit was 100$ cheaper so after i saw what you linked I'm now thinking about going with two of those for 720$ instead of the 470$ i paid for one kit of 4x8GB. end of the day I will have 4 sticks that give me 64GB instead of 4 sticks that give me 32GB for only 280$ more

G.SKILL TridentZ RGB Series 32GB (2 x 16GB) 288-Pin DDR4 SDRAM DDR4 3200 (PC4 25600) Desktop Memory Model F4-3200C14D-32GTZR

is this RAM also guaranteed to be Samsung B die?

Ah, I see, you were doubling your purchase. I was comparing the kits straight up. Yes, assuming they work, that would be a better overall buy for you!

Like I said before, I can't speak for the stability of 64gb Samsung in 4 slots. I just know Hynix wasn't stable in that config. And while testing the 128GB kits, going up from 1,2,3,4,6,8 DIMMS, the 4 dimm 64GB config was clean stable at 3200mhz on both the 2933mhz c16 kit and 3200mhz c14 kit.

That is really good to know, i will see if I can run 4 slots with the one I ordered and if that is the case i will consider going to 4x16GB version

One of my 128gb kits was two F4-3200C14Q-64GTZR, and all Samsung. Its possible that SKU you list in your post is simply half of one of these 64 gb kits, because D and Q just refer to 2 or 4 sticks, and 32 and 64 are the total RAM. So the two kits we are referencing are possibly identical at the stick level.

Saw your other post. Yeah, see what the one you bought does and go from there. That's the best way to go. thumb.gif

Still a good reminder to read through that stuff again!

I reckon with TR it could be more tricky to:-

i) tune CLDO_VDDP
ii) to know if we have a memory hole

than Ryzen as we have 2 memory controllers.

I moved down to 3333MHz as 3466MHz was unstable and encountered post issues. I believe the post issues where memory training errors as I had "Memory D0" on OLED and board would retry post. Since being on 3333MHz I have also experienced post issues, vastly less cases of "Memory D0" although but same error redface.gif .

Sucks as I'm only using 2x 8GB single rank Samsung B die at 3333MHz CL15 redface.gif, hoping this is UEFI/AGESA issues that will be ironed out and hope it isn't that due to further complexity of TR that we are less likely to achieve what we may on Ryzen.

Just had something weird happen to me, after my pc has been running for probably 24 hours, my windows froze and when I restarted it won't pass Memory check until I reset the CMOS. Have you guys encountered that before?
post #1230 of 2021
gupsterg, I was looking into CLDO_VDDP yesterday and couldn't figure out how it worked. It looked like the only value my board would accept (latest bios which I think is 801 or something) was 0 / zero for the value. Does anyone have CLDO_VDDP working cause I'd love to try tweaking this voltage to see if I can my 8-sticks stable at 3200mhz, right now I'm at 3066mhz?

EDIT: I read that this option was recently enabled however I couldn't find anyone actually changing this value with this motherboard, just people tweaking these values on the C6H.


Ivanov88, It sounds to me that you weren't fully stable to begin with. Was your box Prime95 blend and MemTest86 stable for 24hrs each?
