My Watercooled 7900XTX is having some serious issues when compared to others with the exact same setup listed below.

MSI B550 MAG Tomahawk Wifi
5800x3d
7900xtx
WD SN850x 1 tb
64 gb corsair lpx 3600mhz
1000 watt corsair 80 gold

I have tried at least 3 different bios
about 15 different adrenalin driver versions
I've tried drivers only
OverClocking
under volting
Default settings

tried with afterburner, tried in another motherboard Aorus X570

When comparing my stats to others, my scores are more in line with a 3070ti than they are with 7900xtx

See attached scores from Uningine Superposition, Time Spy (sometimes I do score about average as in the attached pic), PassMark. The lower numbers from each benchmark are default and the higher numbers are with OC settings of +15% power, 3000mhz gpu, and 2700mhz vram. All of these were taken within a few days of each other.

I just dont understand, this POS has been giving me issues since I bought it. Constantly having to ddu and reinstall drivers because it crashes my system. When it does work it performs like a $300 gpu and not the $1k I paid for it. AMD refuses to help because I bought it from BestBuy, BestBuy refuses to help since it has been longer than 1 year. Every time this POS gives me issues I want to rip it out of my system and beat it to death with a sledge hammer.

Thoughts other than I have a crap 7900xtx???

I'll run these when I get home - very similar setup to yours.
 
Your CPU score is kinda low? Well configured 5800X3D should be 13k plus or high 12s at the very least. Yes, Timespy CPU score doesn't really reward X3D so it will be roughly similar to a 5800X, but your score is even lower than my 5700G.

Overall score is still higher than my 7900XT was, but whether it's still low overall idk. Certainly not as big a gap as the CPU score.

The later BIOSes (AGESA 1208 and later) seem to change the V-F curves significantly for some 5800X3D, making performance/thermals/power all incredibly bad until compensated for with a hefty Vcore offset. Might be the case, might not be.

You might have to provide some more useful metrics like HWInfo data.
 
There is something definitely wrong, stock vs stock this is barely faster than my 7900XT. I don't know what could possibly cause this, at what clocks is it running ? There is at least a good 15-20% missing performance.

If you had problems with it since day 1 you really should have returned it and definitely not wait until the warranty ended.

This!
 
Run some benchmarks and monitor with gpu z and hwinfo64, post the output.
 
Is it AMD branded? Didn't a good portion of those have vapor-chamber issues? Check thermals. Maybe mention that magic phrase to get AMD to do something.

He's got it watercooled, not air.

Oh, duh. I need more caffeine.

Could be a pump or other water cooling related issue? Dunno.
 
Oh, duh. I need more caffiene.
Come on over and I'll convert you to my insane caffeine consumption. :roll:

As for OP, what are your power draws on the card? Mine does about 360-375w stock.

Fight me bro. I sleep in a bed of discarded diet dr pepper cans.
 
What did you set your core mv to? Also also, try backing the memory back down to stock, it tends to take up extra power from the core from my own experience.

I guess your CPU is throttling. What's your case, airflow and temperatures?
 
Your Superposition screenshots think you have a 7900 GRE?
Nothing new of Superposition showing the wrong model from the same GPU family.
 
GPU Core Clock frequency on Time Spy is barely above 2500MHz, that's on the low side for a 7900 XTX while W1zz's review sample of the 7900 XTX liked to hang in the 2600-2700 range and would boost higher when it had the power budget. But your score is average for Time Spy. Have you enabled the +15% Power Limit? Have you tried undervolting a little to 1100 mV or even 1075 mV to see if it makes a difference?

On passmark my cpu is 99% if supposed to be over 13k on timespy then a little low I suppose. "Well configured 5800x3d" I thought the ONLY thing you could do to these was increase the power like 1% or something?

As stated in original post I have tried everything you mentioned and more. Barely make a difference. The Uningine's are default vs max tuning in Adrenalin.

My gpu never goes over 40c even at 100% load. My cpu highest I ever seen was 71c

Same 350-375

It is AMD branded but I watercooled right away as I did have one with the vapor chamber issues.
 
Pro tip, don't watercool it till you have confirmed card is working 100%.

Well day one issues were driver issues. These low scores are recently. My scores when first got it were way higher and even at these much lower scores I don't really notice it when gaming because the 7900xtx is a beast. It still pisses me off though because I could have spent 600-700 instead of 1k

I don't think anyone has ever used Passmark in the past 7 years for serious benchmarking purposes. Instead of Passmark, you could do a run of R23 to see where your baseline scores are.

5800X3D may be a hardlocked CPU but that doesn't mean curve optimizer doesn't hide significant potential gains, and like I said before the potential huge performance losses in later AGESA that revises V-F tables. Especially if your stock CPU is noticeably underperforming.

It's a little hard to tell just about anything without some HWInfo data under load, at the least.

Running R23 now
 
All HWInfo values after some time under max load on GPU and CPU, Zen timings values, and Aida 64 RAM benchmark latency value could be useful. GPU-Z and CPU-Z as well. Also, have you tried 1.2.0.6c AGESA based bios release for your board?
 
Timespy CPU score is alright if stock. -30 CO, tuned ram gets about 12500-13000 range (Timespy highly affected by ram) I'm afraid it's on the GPU. Maybe also use Radeon OSD while testing to see if there are sudden drops or any unusual values while running (GPU clock, power, usage, voltage etc).

Isn't AGESA part of the BIOS update? I have the newest BIOS. I've tried at least the last 4-5 BIOS versions hoping one would work better. Currently the newest one from 3/2024 I think is installed.
