It's a 9950x3d rather than a 9800x3d, maybe that's part of the issue. Yes the motherboard is probably the one thing I would have changed if building myself or speccing from scratch but I'm hopeful the issues can be resolved. Firmware update is the next step, but have held off because they want me to use their agreed version so want to follow their instructions whilst still in the return period then probably manually setting timings. I'm not sure at the end of the day how much any of this will make performance wise but to me if they are using 6000mhz 64gb in their advertising it should run as such.

Ah, my bad.
Looking back through the thread, I got mixed up with Kingtreelo mentioning the 9800x3d!
Sorry about that, I've been burning the candle at both ends recently with work and stuff.
So it's the fusion 80

Looking at reviews, the motherboard should be more than capable of running your components.
Personally I have no issues with the build, I was under the impression it was the B850 Prime Plus.

Yeah, I'd just go along with what they suggest. The last thing they want is to have the system returned for something that can be resolved remotely. I'm sure they will be able to pinpoint the issue and sort it out.
Regarding performance, bandwidth with a 9850x3d 1:1 at 6000m/t CL30 looks to be roughly in the 80000 GB/s range, not sure of the exact figures as I've not tested one myself. You won't see much difference running slower speeds/latency, but higher bandwidth and lower latency help keep framerate dips/hitches and stutters at bay.
You could try running Aida64, even though it's the trial version you can still see what your Memory read and Memory latency figures are.

Here's a couple of my memory benches at different speeds that I did a while ago. I've managed to tighten up things a bit since I ran these and they are not really comparable to AMD, but it's something to look at. Intel sweetspot is latency under 50ns at 8000m/t CL 34 32gb A-die or 8200m/t - 8400m/t CL36 48gb M-Die, at that point going any faster is going well into the realm of diminishing returns. These benches were using 48gb M-Die sticks at 8200m/t - 8600m/t.
Some people run the benchmark in safe mode to get the best figures as not as many processes are running, but I just run the benchmarks in windows so my latency figures are not as low as they can be.

Yes, that's the one. With the £900 cash back from Very I don't think I could source the components for that money! To be fair to their tech support they seem to have located the issue and are trying to fix it. I'd prefer not to have to return it, but will do if they can't get it stable at the rated speed
2 things, that ram should run on a potato at this point with the maturity of the bios's, and he has a 2 CCD cpu, Ryzen 9950X3D, that and the 5090 are why I feel they cheaped out on the mobo, and somewhat on the ram (since Corsair Vengence is generally some of the cheapest out there (I'm running it fine at EXPO with an X series mobo)
Out of curiosity, what capacity ram are you using? What CL is it?
No ram is cheap these days, especially 64gb CL30. And whilst Corsair ram can be generic slop, it can also be great ram. In some instances the only difference between kits is the heatspreaders.
For general usage, theres not much difference between B850 and X870/E from my understanding. And for someone simply having 1 GPU and a couple of NVMe drives, either will serve the purpose.
I dont have an opinion on whether 6000 CL30 will run on a potato as I haven't tested it myself.
But from a perspective of someone who builds pcs for mates with a use scenario and budget in mind, this build covers all bases and is a good build imo.

That graphic card is 2.5k rest of it aint worth the extra 2k though.Good job I was sat down£4500
If I spent that on a PC I'd need to be retired and be gaming 18 hours a day
Better not add up the value of your cabs then, and how often you play them. LolGood job I was sat down
If I spent that on a PC I'd need to be retired and be gaming 18 hours a day
It's a fair point lol
well roughly all the machines in my house Ive spent about £6/7000 but 2 alone were £3000 being F355 and OutRun dlx cabs and the most expensive i've bought, some I bought i've had money back selling parts I didn't want so brings price down overall, bonus is it's probably £20,000+ worth now
huge amount of my machines were anything from £10-200
Yes, but I paid 3.6k and the 9950x3d is about £600 and the Samsung 4tb 990 pro is at least another £250.....

Not bought a Gigabyte board for my own builds in ages! I did buy a cheap GIgabyte for a budget build for a mate but can't remember the model offhand, it was 50 quid brand new off eBuyer, no frills but worked fine.
Over the past few years I've had a tinker with:
Asus x570 Crossahair Dark Hero
MSI B550 Unify-X
Asus Z790 Maximus Apex
Asus Z790 Apex Encore
Asrock Z790i Lightning Wifi
Asrock B760i Lightning Wifi
MSI B760m Mortar
Asrock Z790 Taichi
All above boards have been solid, no issues at all. I even had a watercooling leak happen on the Apex Encore and it survived that due to a short circuit safety feature kicking in. Once the board had dried out it was fine.
MSI used to be really bad back in the day, but these days as long as the power delivery and vrm cooling is good and you are not using a 50 quid board to power a high end CPU you shouldn't have any issues with any brand.

i have an ASUS MB in my newest build, its been perfect, the wifi gets better speeds than my CAT5 so i unplugged and only use that for emergencies now
I have a question for the pc experts, I checked the ram part number earlier and it isn't on the motherboard qvl list. On further searching it looks like it's 2 separate sticks of 32gb albeit with the same part numbers rather than a 64gb kit. Is it possible this is causing the issue? I didn't get an opportunity to call them today but just trying to think of solutions (yes I know that should be their job 😁)
The part number is cmk5x32g2b60z30a2
The part number is cmk5x32g2b60z30a2

im going to be totally naïve here, but i dont think you can get a single stick of RAM that is 64gb
No, but you can get a matched pair of 32gb in a kit, which this doesn't appear to be.
Usually when you buy a kit, it's a matched pair.
Most of the time there's a serial number on each module (See pic attached, I've erased some of the SN but you can see the last 3 digits), the number should be consecutive showing it's part of a kit. It's been a while since I bought Corsair, but this G.Skill kit has the SN, but a set of Patriot sticks I recently bought didn't.
It *may* cause an issue if they are not actually a matched kit and are 2 sticks from different kits. When using 4 sticks it's best to keep the matched pair as a channel as it can cause issues if you mix them. And I'd imagine it's the same with 2 sticks, but it's been a long time since I didn't buy a kit and simply mixed random ram modules.
