Well, the pauses aren't caused by the Samsung NVMe driver -- I just finished a clean install of the Creator update. With no drivers installed besides what Creator comes with I was able to trigger the pauses with IBT AVX. Back to the drawing board...

After reading the posts regarding the use of LLC by Raja@ASUS, elmor, and the other knowledgeable people here I was forced to re-think my overclock. These guys know transients, overshoots, VRM stress, and such far better than I ever hope to, so I followed their advice which basically amounts to:

"Keep your damn Mitts off those LLC Levels! Just set your voltage correctly in the first place!"

Well, OK then, I can understand that much tongue.gif

So I journeyed back into the land of UEFI, where the use of the sacred F1 is required to succeed in my quest for a 4GHz P-state overclock with LLC set to auto. Through various doomed attempts, I arrived at an offset voltage of .265 compared to .234 volts with an LLC of Level 3. That is .005 more than what I calculated that would be needed for my first attempt at P-state.

That boils down to running at 1549.9 MHz at idle with tctl at around 1.150 volts, and under stress at 4GHz averaging 1.385 volts. Temps averaged 73.2, though I would guesstimate 76 degrees as something near a median after temps stabilized. So now I feel better - 4 GHz and 3200 MHz Dram with no LLC.

Others are having the same pauses. Mine only happens while fully stressing the CPU with stress tests -- never had it happen with CB or any other benchmark. They don't fail the tests either.

Some were thinking it might be a driver issue with the Samsung NVMe driver, but that isn't the case (for me at least).

I have the G.Skill Trident Z RGB 2x8GB 3200MHz CL14 kit with part number F4-3200C14D-16GTZR. These are running on my ASUS C6H board with a Ryzen 1700. Memory modules have the serial number where digit five starts A500 so supposedly they are Samsung B-Die.

Thought I would post my experience so far with the memory as I've seen a lot of people with the same memory either say (1) this memory should work with no tweaks or (2) it is not working for them.

So far I have been unable to get 3200MHz stable with any timings, voltages, 1T/2T, and every beta UEFI released to date (including 1001, 1002, 0079, 0081, 0082, 0083).

I have reset UEFI to defaults, no other overclocking, and tried to set memory both via DOCP and manual. Also tried setting DRAM voltage & boot voltage to 1.45v, SoC to 1.2v, loosened memory timings to 18-18-18-38, tried ProcODT up to 80, etc. I have tried one change at a time and then multiple changes together. Nothing works for 3200MHz -- the system just attempts training, fails with code 0d, reboots, and resets to 2133MHz.

Running the kit at 2933MHz with its rated timings of 14-14-14-34 and 1.35v works great -- no issues at all.

I have gone through every single page of this thread, up to this point, and have tried so many suggestions that those before me have posted. I emailed G.Skill support explaining what I have tried so far and their response was "try one module at a time and try more SoC voltage" however that has not helped. I am waiting for another response back from them although they are replying rather slow.

At this point I have a few days left to either keep the memory or return it and try something else. I did order another kit of the exact same memory and will try that -- thinking perhaps the first set I ordered has some defect.

Ok, another update on my issue with getting my G.Skill F4-3200C14D-16GTZR memory running at 3200MHz.

Bought that second kit of memory, same part number, and tried it with same ASUS C6H and Ryzen 1700. Would not boot at 3200MHz no matter what settings I tried. Works great at 2933MHz.

Bought another Ryzen 1700 and installed it. No other changes here. Now the system boots perfectly with memory at 3200MHz using my original F4-3200C14D-16GTZR kit. Have not had a single boot/training fault at 3200MHz yet. Been testing for the past few hours and gone through 20+ cold/warm boots.

One Ryzen 1700 could not run memory at 3200MHz.
Another Ryzen 1700 can run same memory at 3200MHz.

Some people are saying that the Ryzen IMC is not the root cause -- so if swapping the CPU is the only change then how do you explain one not working and another working ok?

The downside to all this is my second 1700 is not as good of an overclocker. First proc would do 3.9GHz at vcore 1.375v -- second proc is struggling to get 3.9GHz at vcore 1.425v (still doing stability testing).

I am kind of wondering now if I should just get a 1700X and hope that I can at least get 3.9GHz. Would not really mind spending the extra $80. I use water cooling so do not care about the included AMD heatsink/fan (although good to have as a backup if needed someday).

Well I see that as sort of good news, I did not want to try to ditch the Samsung NVMe driver specool.gif

Hmm, 80 bucks or tickle your voltage a tad more - I'd tickle first biggrin.gif

At least you know that chip is running your memory well.. and glad to hear you got to 3200 MHz!

I only notice pauses in IBT which I think is normal for it. But in Samsung Magician with their driver for 960 Evo Nvme, system compatibility
says VID 1022 some functions can't run, blah blah. Rapid mode may become inactive due to system internal errors on some of the AMD//////////AsMedia Controller or Driver. Does everyone get this message or is it because BCLK is 117 for me and going to gen 2?

I have the same message and I'm not overclocking at all (at the moment).

To whoever is stating that 81 WILL be the exact next official bios, I say I will wait till they post it. No need to flash it when there will most likely be some changes, or they would have posted it already.

I have the 1700X with the C6H with the same RAM kit, only boots into 2933MHz...
Tried bumping voltages and loosening some timings to see if I could get to boot 3200MHz and no luck.

So not guarantee the RAM will work at 3200MHz with 1700X.
