XFX RX 6800 SWFT Low clock speed. Temps are good, power is good. | Linus Tech Tips | Page 1

GPU: XFX SWFT RX 6800
CPU: Ryzen 5 5600
PSU: Seasonic focus GX 750W

Core clock won't get higher than 1175-1179. Checked VBIOS- All good, does not seem mined. Loaded a different VBIOS with the same results. Also flipped the switch on the GPU with the same result.
Nothing is limited in windows or amd adrenalin power wise
I am using two separate 8pin pci-e cables from the PSU to deliver power.(everything is plugged in properly)
GPU can handle 2400 OC + UV (900-920mV) + 2100 memory clock with fast timings.
On default settings it consumes about 125W tops.
The gpu is usable but i need to know what's wrong.
The performance is below what you'd see on other rx 6800s in Furmark, 3dmark steel nomad, superposition and Cyberpunk (both benchmark and regular gaming).

What are your idle temps in the sensor tab

this is while running parsec and a web browser

#

potent skiff this is while running parsec and a web browser

Did you get the gpu used?

potent skiff Aug 25, 2024, 9:15 PM

#

yep

#

seals on the back are intact

#

supposedly never used

#

don't think it's another GPU pretending to be a 6800 as it handles 2400 OC+UV quite well

#

no mining bios either

mild dune Aug 25, 2024, 9:16 PM

#

Well the bios can always be reflashed back to stock and you’d never know. Let me do some searching

#

What mobo do you have btw?

potent skiff Aug 25, 2024, 9:34 PM

#

b450 gaming x

#

gigabyte

#

still would it just have artifacts and crashes if it was mined and damaged during that?

#

i'd get the lower clock speed if it had a custom bios

#

don't think pci-e 3.0 would limit clock speeds

#

considering it can do 2400

mild dune Aug 25, 2024, 9:37 PM

#

Go to your bios and set your PCIe link speed from “auto” to “gen 3”

My gb b450 was giving me 65% perf in my 2080 super way back in the day

#

I don’t think it’s related but humor me

potent skiff Aug 25, 2024, 9:39 PM

#

sure

#

Done

mild dune Aug 25, 2024, 9:42 PM

#

potent skiff Done

Are you still in bios?

potent skiff Aug 25, 2024, 9:42 PM

#

Nope

mild dune Aug 25, 2024, 9:43 PM

#

No prob, go try a benchmark

potent skiff Aug 25, 2024, 9:43 PM

#

shit dude

#

haha

#

that was it

#

reached 2000 mhz

#

in furmark

mild dune Aug 25, 2024, 9:43 PM

#

I AM THE BEST

potent skiff Aug 25, 2024, 9:43 PM

#

you are great!

mild dune Aug 25, 2024, 9:43 PM

#

have fun man

potent skiff Aug 25, 2024, 9:43 PM

#

thank you so much!!!!

mild dune Aug 25, 2024, 9:43 PM

#

No prob

odd coyote Aug 25, 2024, 9:44 PM

#

Gigabyte really just needs to not be this ass

mild dune Aug 25, 2024, 9:44 PM

#

(We all have gigabyte boards)

odd coyote Aug 25, 2024, 9:44 PM

#

(false I just helped this tard build an asrock system)

#

Anyways gl with gamin bro, that issue plagued eso for ages till he figured it out

potent skiff Aug 25, 2024, 9:57 PM

#

guys

#

i fucked up

#

i had the OC applied

#

reverting to default in amd adrenaline

#

sets me back to square one

#

@mild dune

#

@odd coyote

#

rip

odd coyote Aug 25, 2024, 9:59 PM

#

Ripppp

#

Hmm

mild dune Aug 25, 2024, 9:59 PM

#

Hmmmmmm

potent skiff Aug 25, 2024, 10:00 PM

#

usually amd resets the OC on startup because of some windows update i can't uninstall anymore

#

no graphics driver crash or anything

#

so i didn't bother to check after restart

mild dune Aug 25, 2024, 10:01 PM

#

Are you familiar with RED bios editor

potent skiff Aug 25, 2024, 10:02 PM

#

not at all

mild dune Aug 25, 2024, 10:02 PM

#

I want you to download your bios in GPU-Z, then open it in RBE. You can find the download from Igor’s lab or techpowerup

potent skiff Aug 25, 2024, 10:03 PM

#

on it

mild dune Aug 25, 2024, 10:03 PM

#

Post screenshots once you are viewing the tables of ur vbios

potent skiff Aug 25, 2024, 10:03 PM

#

not supported

#

hmm

odd coyote Aug 25, 2024, 10:06 PM

#

Eso says u might need to get morepowertools from igors lab for it

mild dune Aug 25, 2024, 10:07 PM

#

Ya my bad RBE is the old one

potent skiff Aug 25, 2024, 10:09 PM

#

OC limits?

mild dune Aug 25, 2024, 10:09 PM

#

Did you find the software? Sorry I’m being vague I’m at work lol

potent skiff Aug 25, 2024, 10:09 PM

#

#

same lol

mild dune Aug 25, 2024, 10:11 PM

#

Shit that looks good.

potent skiff Aug 25, 2024, 10:12 PM

#

yeah..

#

as far as i can tell anyways

mild dune Aug 25, 2024, 10:13 PM

#

Can you run a 3dm timespy

#

I know it’s not gonna stress much but I want to see the results page

potent skiff Aug 25, 2024, 10:14 PM

#

don't have it

#

steel nomad

#

is what i have

mild dune Aug 25, 2024, 10:14 PM

#

It’s free if you have 3dmark on steam

#

Ok

#

Only thing I can think of is windows 11 power settings at this point

#

Make sure it’s all set to full perf

potent skiff Aug 25, 2024, 10:15 PM

#

nvm i can run timespy

mild dune Aug 25, 2024, 10:15 PM

#

Do it

potent skiff Aug 25, 2024, 10:15 PM

#

tried high performance mode

#

#

gpu clock tops at 1170 in this one

mild dune Aug 25, 2024, 10:28 PM

#

Why is it not plotting your gpu temp on that chart? The core just isn’t boosting

#

Can you toggle that graph at all if you still have it open?

potent skiff Aug 25, 2024, 10:30 PM

#

yep

#

#

quite low

#

47 tops

#

at 99% load

mild dune Aug 25, 2024, 10:33 PM

#

Can you reapply the OC? Also do you have another pc that you could put this card in to see if the behavior is consistent

potent skiff Aug 25, 2024, 10:33 PM

#

don't have another PC but i can apply the OC and run the benchmark

mild dune Aug 25, 2024, 10:34 PM

#

Ok 👍

potent skiff Aug 25, 2024, 10:34 PM

#

which looks like this

mild dune Aug 25, 2024, 10:35 PM

#

Can you run another timespy now?

#

Then show those 2 charts again

potent skiff Aug 25, 2024, 10:36 PM

#

Yep on it

#

It’s a bit annoying that it takes time to run a cpu test too

#

And the demo

#

What do you think we’ll find out with this test?

mild dune Aug 25, 2024, 10:39 PM

#

I want to see if your gpu is capable of running at normal clocks now. If it is, then we know it’s a driver/software problem and not a hardware problem

#

Have you used DDU before?

potent skiff Aug 25, 2024, 10:41 PM

#

#

yep but this is a fresh windows install

#

no other drivers present before

#

\

#

with oc it reaches ~2200

#

57 degreees celsius

#

so with OC it's a slightly below average card KEK

#

336 USD

mild dune Aug 25, 2024, 10:47 PM

#

Can you open event viewer and look for any errors related to gpu drivers or amd

#

I don’t remember which category they will appear under but you can figure it out I’m sure

potent skiff Aug 25, 2024, 10:49 PM

#

can't see anything gpu driver related

mild dune Aug 25, 2024, 10:50 PM

#

Also have you reset your bios settings to stock since you did the fresh install of windows?

It’s gotta be either the gpu hardware, or a bad bios setting from your previous install.

#

Or PSU? I’m trying to think of anything that hasn’t changed

potent skiff Aug 25, 2024, 10:50 PM

#

bios was reset after the install

mild dune Aug 25, 2024, 10:50 PM

#

Ok

potent skiff Aug 25, 2024, 10:51 PM

#

PSU is brand new A tier

mild dune Aug 25, 2024, 10:51 PM

#

So basically when you fresh install drivers the core speed can’t reach advertised speeds?

potent skiff Aug 25, 2024, 10:51 PM

#

would secure boot/ TPM impact anything?

mild dune Aug 25, 2024, 10:51 PM

#

No

potent skiff Aug 25, 2024, 10:52 PM

#

yep

#

i could try DDU but i'm not feeling optimistic about it

mild dune Aug 25, 2024, 10:52 PM

#

Can you DDU, restart, reinstall drivers from adrenaline, restart, and run timespy one more time. Don’t touch OC or anything.

#

Hell even reinstall Adrenaline

potent skiff Aug 25, 2024, 10:52 PM

#

sure

#

safe mode mandatory i suppose

potent skiff Aug 25, 2024, 11:16 PM

#

done with DDU

#

rip

#

#

so cooked hardware?

mild dune Aug 25, 2024, 11:24 PM

#

potent skiff

Yeah best you can do is try older drivers at this point. It’s either a really specific bug with the drivers and your version of windows, or hardware

#

Rip

potent skiff Aug 25, 2024, 11:24 PM

#

hope it's software KEK

mild dune Aug 25, 2024, 11:25 PM

#

You could make a bootable ubuntu usb and try to benchmark the card LOL

potent skiff Aug 25, 2024, 11:25 PM

#

sure why not

#

but not right now

mild dune Aug 25, 2024, 11:25 PM

#

Yeah, that’s all I got at this point sorry dude

potent skiff Aug 25, 2024, 11:25 PM

#

no worries

#

thank you for your time and help!!

#

card still works great with OC

mild dune Aug 25, 2024, 11:27 PM

#

On your timespy score graph there is a blip in your range that shows other people have similar scoring cards. Guessing you’re not the only one with this problem

#

potent skiff Aug 26, 2024, 1:35 AM

#

shit i did not see it

#

yeah

#

but i scanned the web quite a bit before asking for help as not to waste anyone's time

#

but to no avail

potent skiff Aug 26, 2024, 1:31 PM

#

any chance reseating the gpu would help?

mild dune Aug 26, 2024, 5:13 PM

#

You can give it a shot

potent skiff Aug 26, 2024, 6:10 PM

#

resize bar can't hurt, right?

mild dune Aug 26, 2024, 6:32 PM

#

potent skiff resize bar can't hurt, right?

Shouldn’t have any bad effect

potent skiff Aug 26, 2024, 6:32 PM

#

friend got a 6800XT second hand from the same guy which works as advertised

#

maybe i got a bad one

#

or maybe win 11 is messing with me

#

tried to run linux

#

but i couldn't get a benchmark to run haha

mild dune Aug 26, 2024, 6:33 PM

#

Oh lol that’s fine. You can always install w10 and see if that changes anything

#

It’s a pita but I’m running out of ideas

potent skiff Aug 27, 2024, 1:07 PM

#

windows 10 install did not help

potent skiff Aug 27, 2024, 3:05 PM

#

Christ dude

#

im sorry for wasting your time

#

hope the puzzle was somewhat fun to you

#

you know what the issue was?

#

the bios switch

#

the first time i flipped it, it did not do anything and then i restarted, flipping it back

#

this time on windows 10

#

i flipped the switch

#

powered computer on

#

and win 10 gave me a notification about hardware changes and needing to restart

#

so i restart

#

#

mild dune Aug 27, 2024, 4:08 PM

#

Was it in like eco mode or something lol?

#

I thought the dual bios on those cards was used for normal perf and increased perf haha

potent skiff Aug 28, 2024, 12:27 AM

#

yeah no idea
