Question Getting some Really low scores compared to others on FurMark with RX 6800.

[Axolotl_98]

Hello,

So, I just bought a refurbished RX 6800 and ran furmark on it, here is my score: FurMark Score Result

Compared to others with same card my results are quite disappointing, I have seen others with RX 6800 going upto 200+ FPS on 1080p, while I am at 180, Is something wrong with my card should I return it?

Just in case an Image as well:

RX6800 is a 250W rated part. So 227W is a little low and the temperatures look a little too good for running furmark.

Max boost clock is only 1953Mhz. Looks like the default is normally 2105Mhz on other off the shelf units. The BIOS on this one may be different. Either someone messed with it before it made it to the refurbisher, or they put a lower power BIOS on the card to make it stable when it wasn't stable at stock settings.

What does GPU-Z say about the max boost?

Within 10% isn't terrible though, just to be clear.

Hi, Here is the screenshot of GPU-Z, Should I mention that to the store? There is almost a 20 fps difference but the temperature is cooler. I would rather have stock settings.

Let me know if There is something else I can share.

What psu do you have? Ram speed? Hard drives full? Are you pigtailing the 2 power connectors to the 6800 or are the 2 independent lines from the psu?

Any massive draw on the system when idle?

Also look up how to enable resizeable bar in bios, that should help. Currently shows disabled, that could account for the loss.

PSU: MSI MAG A1000 Watt (I can't find enough information about this, mostly MPG comes up but mine is MAG)
RAM: Lexar 16GB x 2 (3200 MHz) Not fancy RAMs.

It's a brand new 1tb SSD NM620 also Lexar. (Only one partition 'C')

I will ask the Store about BIOS stuff, I am not very well versed in doing these things own my own.

I think the lines are independent, since they seem to be different cables, see the picture:

I agree, resizeable bar can gain performance. Basically allows the CPU to send larger chunks of data to the GPU. Though I wouldn't think that would do anything to Furmark.

Max boost is listed as 2190, so not sure why it isn't aiming for that. Looks like it is staying at or under the baseclock, which is not normal behavior.

Load up MSI Afterburner and see if you can get it to boost or increase the power limit. If it can, then it is some sort of software issue.

Does this card have a dual bios? A quiet and performance setting?

 

[Eximo]

Good idea. Some XFX RX6800 appear to have dual BIOS, though they don't make mention of a quiet vs performance mode.

I may have used the wrong word in performance. OC and Quiet might be better but it was my first thought when I saw the lower boost and power usage. Only because I have been down a rabbit hole before only to find a switch would have sorted things. Let's see if there is even a switch I guess
