@GecKoTDF I don't know if you're still around, but I found that I can't hit as high of an overclock on the der8auer custom air bios you recommended. I'm way limited. If I customize my stock bios to use the same settings as the unlocked air bios I can hit my overclock and have all the power settings plus the advantage of having my overclock built into my bios. Same settings on the der8auer unlocked air bios and I'm unstable. That explains why I couldn't get my overclock with asus's utility. It wasn't the utility it was the bios. Since you're running that BIOS I thought I'd let you know. The workaround for the bios signing is a pain to implement but works great for me. could just be that bios vs. my card. You're experience may differ. I upped the power limit slightly from the der8auer settings and got a slight bump in bench scores. I'm still fine tuning it. I need to get the killawatt back out and my temp sensors to make sure i"m not pushing anything too hard.

Just got done overclocking my memory. Did I hit the ram lottery because on my rx 470 4gb I can hit 1945 mhz on the mem without anymore voltage. I can even get 2000 mhz but after a couple benches ill crash.

Let me see my english it's not the best - I never test the "default" bios of my card 10 minutes after put it in the PC change the bios no RMA in Argentina - Well, so you think the der8auer bios its not the most stable ? - I try edit my bios with the "Polaris Bios Editor" with the der8auer configuration like you made because I think thats the best way, you save you stock factory bios and put new information but, without luck, when I save the bios and flashed into the video card Windows not start well only 640x480 resolution.-

First, how you edit your bios? manually?

If you want, you know I have water cooling, can you send me your original but modded bios with power unlocked like der8auer I can flash and test if I can get better overclocks, if I get it, its the der8auer broken, if I have the same, probably its the der8auer bios with your GPU

Sounds about right in regards to exceeding the point where the memory can't correct the errors it is experiencing.

Run HWInfo and look at its sensors window for the entry "GPU Memory Errors" It should read zero, though you can get away with a few errors a second - even a hundred - and still gain performance... probably not the best of ideas, though, to exceed the single digits per minute.

It seems like a useful tool but even at stock I have exactly 245 memory errors.

Also the 16.8.3 drivers have seem to tank my performance. Literally halved my unigen heaven preformance.

I used the Polaris BIOS editor and I'm using windows 10 test mode and a driver patch made available by Lordkag at http://www.win-raid.com/t892f16-AMD-and-Nvidia-GOP-update-No-requests-DIY-19.html#msg30028 and the test signing utility listed there. generaleramon, the op of the Polaris Bios Mod thread and gupsterg worked with Lordkag on the patch and procedure. I'll have to donate to that forum because it worked well. Only problem was my anti-virus didn't like the test signing program. I had to run the test signer in safe mode but launch it from an elevated command prompt because it wouldn't launch in safemode by right clicking and choosing run as administrator.

My bios has my overclock built in which you don't want but I could send you a bios without the overclock built in but the same power unlocks to test. It'll take me a bit. I'm multi-tasking. My stock bios is the sapphire 8gb reference rx480 bios. That's what I'm working from.. You'll need to do Lordkag's patch though. it'll lock you in to 16.8.2 driver version to as there are only patches for 16.7.3 and 16.8.2. It may be more trouble than it's worth to you.

It's not that the unlocked air bios is unstable, I just couldn't overclock as high with it and I needed much more voltage for the same frequencies. I was trying to bake my overclock into it. It was easier to bake his power unlocks into my bios and bake my overclock onto that. I added another 10% on the power limit. You may not want that either as you're running 2 cards. Let me know if you want to try.

I've gotten the same problem a couple of times. going to reset the driver in wattman, doing a cold boot and reapplying my overclock usually fixed the problem. I caused the problem when I edited the memory clocks while hwinfo was open. I got locked in to low memory clocks or something.

I see, well that's what I want, Your bios with the unlocked TDP, Ampers, Voltages,etc but without the clocks, like the der8auer BIOS but, in this case in your dump, so I can start to check, first my clock's and then try to go more high, If I can do it, means the der8auer bios have a problem in some way, and thats going to be a nice discover, and if I can't go more high, means probably the der8auer have a trouble with your video card.-

You are looking for the change in numbers, not the actual count (since the count is cumulative).

If the numbers stop going up, you are no longer getting more errors.

It is easier to see if you have something like Furmark or Tessmark running in a window while you changing the memory clocks. Then you will see the errors start to build.

You are looking for the worst-case error accumulation rate. If you have only 5 or so errors a second, you're really at the limit of where you want to push the clocks. Those errors represent a memory bit failure that was correctable. With so many bit in play, the probability of a fatal error is still rather low, but they climb rapidly over time (meaning you can still see the random crash).

A proper, on-the-edge, memory overclock will have less than one error per minute. You had 245 in a span of what I can only imagine is, maybe, a minute... and probably while not stressing the system. That means your clocks are too high.
