Buying used 7900xtx. What to look out for?

[gusty quiver]

I decided that its a good time to update my GPU. After considering lots of things, i decided to get 7900xtx.
My options are to either get a new one from retail for 1300$, or used one for 850-1000$.

As with any second hand hardware, i will be testing it at the seller's place before buying it.
But its not like we can sit there all day running benchmarks, so what tests are the quick surefire way to see if theres something wrong with the card?
What temps should i be seeing for 7900xtx?
Anything i should watch out for?

If temps are too high, replacing the thermal paste will probably fix it

3dmark for benchmarking and furmark for stress testing are my go to

[gusty quiver]

thanks

[gusty quiver]

its "bought half a year ago" 7900 xtx asrock phantom gaming oc

[gusty quiver]

so unless he messed with it badly, it should display close to stock temps

and i see conflicting info on what PSU i would need

as some posts on reddit say that 750-850W is enough (my PSU is 850)

but the retailers recommend a 1000W one

(my cpu is 7600X, so not the most power hungry one)

[clever kernel]

No, it can increase overtime

But it'll be fixed by replacing the thermal paste

[clever kernel]

What's the model?

[gusty quiver]

Deepcool PQ850M

[clever kernel]

Great psu

[gusty quiver]

ik, out of options available at the time this one was the best according to the spreadsheet

[coarse jackal]

The temps can vary depending on airflow and workload, but it’s not the thing that I’d think of

[gusty quiver]

then what would you think of? besides the GPU hitting the claimed specs during furmark

[coarse jackal]

I’d do a benchmark (and compare results), pull up gpu-z, and check for windows errors

[coarse jackal]

Furmark is not a good benchmark

[coarse jackal]

Here are some good alternatives

[clever kernel]

Furmark is not for benchmarking

It's a stress test

[coarse jackal]

Exactly

[coarse jackal]

Well there is benchmarks

[clever kernel]

Who are you going to compare results with

Ain't no one using it for that

[coarse jackal]

[coarse jackal]

Remember that people use Userbenchmark

[clever kernel]

Right right

[gusty quiver]

nah id look at furmark to see that it hits the promised clocks and see the temps under load

[coarse jackal]

Hm ok

[coarse jackal]

But still look on gpuz, it’s even integrated into Furmark anyway

[gusty quiver]

yep

just wish it was easier to find what to compare the numbers with

[gusty quiver]

ig i will try occt

am kinda worried now, since ill be also bringing my GPU for tradein

what if there are issues with my gpu found during testing

cant even test it now cuz already removed both card and drivers, and will drive with it there right after work😔

worst case im just not gonna tradein ig and keep it for my home server

[coarse jackal]

what gpu? ¯_(ツ)_/¯

[gusty quiver]

3070Ti

palit gamerock

never serviced

bought it second hand in 2022 i think and it was in my pc since

[quick gate]

Alot of people sold XTXs in the UK second hand. Nothing wrong with them, they panic bought and realised they never really fully utilised the GPU so cashed in and down sized. Imagine its the same elsewhere

[gusty quiver]

yeah but when buying you want to make sure you arent getting a faulty product, no?

lots of people downsizing doesnt always mean this particular one isnt a bad actor

[quick gate]

Most people not utilising it fully, unlikely to get something that’s gone bad or wrong. An XTx atleast in the Uk, never heard of someone buying faulty.

[gusty quiver]

while i see what you mean, this isnt quite the information i am looking for.
I agree that its unlikely that the GPU is bad.
But the point if my question is - what to look at to make sure it isnt. I wont know what the previous user did with it, and its not like i can take his word for it. theres no cheque, no warranty, not even box

[gusty quiver]

well i bought it

didnt sit through entire hour of occt

but first 10 minutes looked good enough

not sure if 102C hotspot after continuous max load is good or bad

unlikely to ever reach that during my normal use

but i might just undervolt it or set some limits instead so it doesnt reach so high

[quick gate]

XTX does run hot yes. Around 100c isn’t unusual on hotspot

[coarse jackal]

Hm? My 7900gre is 66°C hotspot

[quick gate]

That’s gre . Not an XTX.

That’s like me telling him my hotspot on my 7800xt at 100% gpu utilisation with RT is 84c. It’s not the same card.

100c is normal for the XTX hotspot. it’s running close to its power limit as a card.

after some testing at home, the fan noise is uneven

so slightly annoying under load

couldnt find a separate control for fans in amd's app

will check out if asrock has anything today after work

[coarse jackal]

FanControl work for my gpu

[gusty quiver]

looking at the replacement guide it seems that all 3 fans are chained together, so no separate control

[coarse jackal]

Of course

[gusty quiver]

im debating if i want to do fan replacement or just straight up remove shroud and slap some 120mm fans there

[coarse jackal]

Try controlling them

First

[gusty quiver]

yeah ill be looking at it in like 11 hours when i get home

until then just thoughts and research

[clever kernel]

meh probably would benefit from a repaste

[clever kernel]

u arent pushing the gpu

[clever kernel]

all 7000 cards run at their power limits

[gusty quiver]

i wont open it up unless im certain that its necessary

just excessive risk

and in general its easier to resell the card later if it has all the stickers in place

[clever kernel]

u dont need to remove the sticker

[clever kernel]

u use something like this

not a screwdriver

[gusty quiver]

[clever kernel]

it works and u still have the sticker

[quick gate]

I can get 320 out of my 263w 7800xt which allows a manual 15% above. By default it’s nowhere near its power limit

[clever kernel]

thats running at ur new power limit

[coarse jackal]

Don’t bother overclocking on Linux, also Im at 1440

[gusty quiver]

used that to manually change fan speeds.
result:
annoying noise starts after 35% and becomes almost indistinguishable after 80%

the noise itself leads me to believe that one of the fans might be off balance, as instead of a consistent humm its more like a repeating pattern, which speeds up with increased rpm

[gusty quiver]

yeah i feel like that requires replacement

cant seem to find the right fans on aliexpress though😔
