Re: XFX 6900 XT merc, hard stuttering and audio dropout

Intel® Core™ i7-5820K Processor (15M Cache, up to 3.60 GHz) Product Specifications

Yep, I thought as much but didn't want to jump on the old x99/socket 2011 deal. I think the card is more than the current components can handle. Green screen is the voltage too low, clock too high. If you adjusted the VRAM up, that will do it too. Try leaving the clocks at stock, but moving the minimum clock to within 100Mhz of maximum. Leave the voltage stock. But do turn the zero RPM fan off. Moving the clocks closer should help with or eliminate the stutter. The minimum clock shouldn't cause a green screen but undervolting the GPU might or if you raised the max clock at all. 

Another thing you could try is reducing the GPU clock to 2100/2300 min/max, VRAM 2100 or stock, zero RPM fan off. The next lowest for that card is 1900/2000 min/max, VRAM stock or 2100, zero RPM fan off. Voltage left stock. At the end of the day it might be like trying to knock a square peg through a round hole. The board is a PCIe 3.0, the oddball Intel 2011 they made for about a year in 2014, 2400 RAM is no help either. The GPU is nearly more powerful than the entire PC, lol. Hopefully one of these "tricks" gets it running decent for now.

Now as far as building an AMD based PC, if gaming and medium work load is all you need, go with the 5600X. It's fairly cheap and available. An affordable B550 motherboard or an X570 is the next thing and go with a $70-100 DDR4 3600 16GB RAM kit. Really affordable is the 3600X like I'm running, paired with an X570 board. The 5800-5950X CPU's are not the best for gaming, more geared towards work but if you really need the best of both worlds of work and play then the 5900x is the top dog. The 5950X is not a good gaming CPU and the 5800x is not worth the money difference of the 5900X that out performs it in work loads. Read some reviews and you'll see that as far as pure gaming with a 5000 series, the 5600X is the best overall. Much like the 3600X was the best in 2019-1st quarter 2020 for gaming. In any case ~$500-600 gets you all you need to finish an AMD build using a 5600X or 3600X.

Re: XFX 6900 XT merc, hard stuttering and audio dropout

I'll test the lower clocks when I have the chance, but outside of that I'm probably not going to do much else before I get my new parts. 

I actually have a 32GB 3600MHz kit sitting here, waiting for my motherboard and 5900x to come back in stock. Hah. 
Been on a waiting list from my local retailer since early November, it truly sucks, but that's just the situation now I suppose. 
Nothing I can do but wait, just have to contain my frustration for now. 
Appreciate the help though.

Re: XFX 6900 XT merc, hard stuttering and audio dropout

Why not skip the 5900x and get the 5600x off Newegg for less? Unless you do video editing or some massive work load, that 5900x is all ego, lmao. Fleabay even has the 5600X for ~$400 and the 5900x for $780. Unless you pre-paid, then your stuck. Check this out:

Amazon.com: AMD Ryzen 5 5600X 6-core, 12-Thread Unlocked Desktop Processor with Wraith Stealth Coole...

Amazon.com: AMD-Ryzen 9 5900X 4th Gen 12-core Desktop Processor Without Cooler, 24-Threads Unlocked,...

Crazy if you don't need the 12 cores for real work. Newegg has nada. Boards?

AM4 AMD Motherboards | Newegg.com  Pick you poison.

 As far as 32GB RAM goes be careful on the board. B550's tend to be "daisy chain" memory and have issues running 4 sticks at 3600. The X570's seem to be much better as most are "T" topology. 32GB is overkill for gaming as well. We can't even max 16GB yet, add the 6900 XT and never getting close to using 16GB RAM. I have 20+ years building PC's, had my own business for about the same time frame. I know all about the overkill, lol. Been there, done that.

Re: XFX 6900 XT merc, hard stuttering and audio dropout

Should have mentioned that I'm located in Norway, Newegg is a no-go for me. 

5600x and 5900x have not been in stock since release, but recently the 5800x has been in stock all the time, but the 100-ish dollar difference between the 5900x and the 5800x doesn't make that much sense to me when I have the money. 

When I was reading on boards the x570 Tomahawk seemed to be a good performer with pretty good power delivery, I went for that since I also got a discount on it together with a 4th Gen Corsair M.2 drive. (1TB). 
I'm more than fine with a little overkill :smileyvery-happy:

Re: XFX 6900 XT merc, hard stuttering and audio dropout

You European guys always have the most trouble getting parts and you're closer to China! In Norway, yes, go for the overkill because you only get one chance at these parts, lol. The X570 Tomahawk should be ok, but all MSI boards seem to give problems with 4 sticks of RAM since they mostly use "daisy chain" topology. I would advise going with a Gigabyte Aurous Elite, Asus ROG Strix, if you must have MSI the Godlike has "T" topology and is very much overkill. Perhaps they'll give you the discount on that M.2 for one of those boards. If not, weigh the potential headache if the RAM doesn't work right out of the box. I fielded a lot of complaints on MSI Tomahawk boards, they were all B550 or B450, maybe the X570 will be different.

Re: XFX 6900 XT merc, hard stuttering and audio dropout

I have 5900x with tomahawk. 
Only problem with 5900x is the heat!
So make sure that you have a decent cooler with it!
I had to put a manual overclock 4450 all cores to keep my temps at bay.
If I were you I would order from few places and get the fastest one. Like you said money is not an issue?
I had 3 orders from 3 different stores. After I got one I canceled the other ones.

Before you do get those new parts and before amd releases new drivers for 6900 you just need to keep finding the right clocks for some games. 

You could try to use vram with fast timings too. (VRAM TUNING- Memory timing)
Undervolting is way to go BUT I tested some games and if you put full 15% powerlimit some games start to stutter. With 5-12% seems to be ok with my card.

Re: XFX 6900 XT merc, hard stuttering and audio dropout

I caved in to the waiting time... 
I really wanted it to be solved with changing my PC parts, but that doesn't seem to be the case...
This has to without a doubt be a driver issue, but I'm reading that this issue existed on the old 5000 series as well. 
In the end if possible, I'm going to return the card... 
I don't want to pay 1500 dollars for a card that doesn't function as it should.

Re: XFX 6900 XT merc, hard stuttering and audio dropout

Sadly, you might need to RMA it. It seems a few are having issues with the Merc line in general. XFX messed up possibly. Also to be sure, make sure you are using 2 PCIe power cables on that. Each cable can only handle ~300W and 9A. So even with a single 12v rail PSU you need to run 2 cables for stability. Full tilt think 2.5W per frame and the card using ~14A or more.

The 5000 issue was different. It's not the same as what you're describing and there's no known audio issues with the 6000 series until this. Frame stutter, yes and that can be the power limit or voltage too high. Clocks too high are another or VRAM sett too high. Using the "fast" option for the VRAM is best over increasing the frequency. However, in my case my OC failed at lower VRAM frequency as opposed to maxing it out at 2150. Very odd. In any case, my card worked out of the box as any card should without going through hoops. 

If your RAM is checking out, the PSU isn't defective, nothing weird like a board standoff shorting out the board or a broken USB port/SATA connector, the CPU is seated and cooled properly, and the BIOS is the proper one and also set right, you might have a bad card.

The 319's look good but there are a few that RMA'd theirs. If you do return it out right, might want to try a Gigabyte WindForce, they seem to run fine.

Re: XFX 6900 XT merc, hard stuttering and audio dropout

It's def a driver problem, got my hands on a brand new XFX RX 6800 XT Merc and it has the same problem, lags when clocks drop, audio stutter and high DPC...

Re: XFX 6900 XT merc, hard stuttering and audio dropout

Latency monitoring programs are total junk. They seem popular in Europe, linked to viruses and other malware, Windows highly recommends NOT using one, the list goes on. 100ms isn't a Windows issue or driver issue, that's what these programs play on. They tell you there's this "DPC" issue and you'll either pay these guys for some software or buy some hardware to "fix" it. If you have a latency issue so severe it causes audio dropout's or pops, etc., it's probably RAM timing or a CPU issue. Or it's the fact your phot shows high latency in the HDAudio BUS, which would be the motherboard's audio not in use because you are running a Sound Baster AE! 

Your sound should be coming out of that Sound Blaster card, not the GPU. So you need to check what audio source you're using as "input" & "output". For the GPU it would be the AMD High Definition Audio Device. For that card it would be the Sound Blaster AE, mine is the Sound Blaster Z. Creative had a problem with audio drops and such recently with the AE. In any case, toss that DPC program, it's utter non-sense. The last time anyone tried to introduce that was in 2016. It's still a junk program/potential malware hazard. 

Your radiator is upside down as well. Hoses need to go down or you need to remount the radiator to the top. You'll get an air pocket in the top tank causing the pump to suck air and you will eventually burn out the pump. The AIO's only come about 90% full on the best of them to leave room for expansion. So you want the hoses 100% submerged in liquid. Read up on that on Gamer's Nexus on YouTube, there's a whole video on how we all mount radiators wrong and why it's a problem. Radiator fans should be pushing out as well, that's in the video too. So if yours are pushing out now, you're pulling hot air off the GPU into the radiator.
