6800XT not boosting over 2470. Is it the switch?

Hi all. I got the 6800XT installed in my PC yesterday. It works lovely, but for some reason it will not OC past 2470. It is the Strix model, and has the switch. This one.

I have noticed that the fans do not spin at all until I put a load on it. Neither the two 120s or the blower for the fets etc. Is that why I can't clock it past 2470?

Sorry for asking. I'm not being totally lazy it's just a arse pain to get to the switch given the case I have.
 
ASUS has placed a dual-BIOS feature on the STRIX that lets you switch from "Quiet" BIOS to the "Performance" BIOS. The difference is fan RPM and a bit more cooling performance. The clock frequencies and power distribution are identical in both modes. Both BIOSes also offer fan stop in idle, meaning the card is passive there.

from a quick google.
 
Fans generally don't spin up until ~47c odd depending on the card. It's not the reason why your GPU can't go past 2470Mhz.

Are you increasing the voltages as well or just trying to boost the clocks on stock voltages? I would imagine for that speed the default volts won't be enough.
 
Also from a quick google:

Speaking of overclocking, you can use Asus's GPU Tweak II (and GPU Tweak III) software suite in addition to the built-in Radeon Software options. By default, like many of Asus's graphics cards, the 6800 XT ROG Strix LC will run at 'gaming' clocks, and you need to install GPU Tweak II and select the OC profile to unlock the full potential. We did this for our testing, though the difference between 'gaming' and 'OC' modes is pretty minimal.

ASUS Radeon RX 6800 XT STRIX OC Liquid Cooled Review - Incredible OC Potential

The ASUS Radeon RX 6800 XT STRIX OC LC comes with an integrated 240 mm watercooling unit that achieves outstanding temperatures. We found unbelievable overclocking potential on our sample, much better than all the other RX 6800 XT cards we've tested before.

its in quiet mode, look at the switch top right. Quiet mode, hence why the fans go quiet. Q Mode - Q for Quiet shhh its Quiet Shh because its being restricted shhhh :cry: MOVE IT TO PERFORMANCE MODE (P Mode, P for Performance) to release it into the wild and let it fly.
 
2360 is the advertised boost so if its going to 2470 by itself then thats better then you should get.

if you cant maunally go higher its power or voltage, try using msi afterburner and setting custom voltages and clocks
 
OK have figured it out. I had an install of Afterburner on the PC, so when I installed the Asus one *and* AMD drivers (which included an overclocking app) it was all a bit much.

Clicking the button in the Asus app gives you 2470, the same as any other. I did get it over 2700, but my scores decreased. Which was odd. A few tests in and the screen started acting up. I am pretty confident that was not the card itself. At all. I am more than confident it was the 60cm ribbon I have in the case that is not PCIE4 verified.

Given the cost to replace the ribbon I am more than happy with 2470.

That could be it tbh. I don't want to mess with it any further for now. It's very important I am able to play PUBG most nights :D I didn't touch the voltage because it's the first Navi card I have had. So I really don't know what the heck I am doing lol.

I'm really happy with the performance uplift from the 2080Ti Kingpin. I used to max at about 168 FPS and see lows of 100. Now I am seeing lows of 140, highs of well over 200 and averages that used to be max FPS.

It's not as odd as it might first seem. Nowadays it's far from unheard of for higher max clocks to result in lower performance.

The reason is throttling, either thermal or power draw. It's easily overlooked because simple monitoring of clock speeds usually won't show it and monitoring of temps won't show power draw throttling. You need software that will monitor throttling, which I think most if not all monitoring software will do. Preferably software that will monitor the number of times throttling is applied as that's far more useful than just knowing it happened at least once.

The most striking example I've had was a Radeon 7950 I had a while back. I got a ~30% increase in performance and ~20C reduction in the worst temps with lower max clocks by undervolting it. I tried various combinations of voltage and clocks and that was the best performance I could get, even without considering the reduced temps and reduced noise. That was an extreme case, though. The card was effectively over-volted out of the box, perhaps to achieve higher clocks for marketting purposes. It couldn't reach those clocks at a lower voltage, but it was power throttled much less and thus had a much higher performance.

You could try monitoring for throttling events and if you see power throttling then you could try undervolting (which will probably require reducing clocks to maintain stability) and maybe increasing the power draw limit throught software such as Afterburner and benchmark with various combinations to see which is best. Or not, since you're really happy with the card as is and you don't want to mess with it any further for now. I've been running my current card (a 1070Ti, bought soon after release) bone stock for years now for the same reasons. I did some "Donkey Kong overclocking" (How high can you go?) for sport when I first got it, but found very little headroom for performance increase. It was a very well cooled and very well optimised card straight out the box. To get anything more out of it I would have had to power the cooling seperately to give the card a bit more power for the card itself and probably gone to water cooling.
