Polaris Bios Editing ( RX5xx / RX4xx ) - Page 173

post #1721 of 3402
Jeztur I feel these numbers will decrease errors & increase stability possibly worry free. It's all about finding the precise max rpm of the fan's capabilities while going just a tiny smidge over.

2867rpm - temperature & pwm adjustments - 80C - 88C - 88C

1313Mhz Core for 84 GPixel/s total : 378GTexel/s total : 540GB/s total

Stock voltage

80C and clock drops until fan kicks up to cool below 80C core to let it eat.

Max Temp is the value key for continuous stability. Shutdown is pretty well ignored, I saw VRM once rise well past 93C.

So 80C Core Max, 88C Shutdown (Pretty Well Ignored/ Still abides by stock 109C), 88C Hotspot (It abides by the hotspot). If 88C is unstable then we shall lower it to 80C as well.

I'll give these a try in the mean time i wanted to show you stock .153 bios vs. the 1320 2120 84-88-84 ones I just tried.

The difference in FPS is temperatures. Specifically the Max Temp and Hotspot. If we raise Hotspot to what 100C? It will perform faster, but that's too hot man. We don't want to melt the mPGA solder balls. haha

We are still picking up memory errors which is no good. Try 1313 : 2110 and re-test.

Also the first run through on my bios is the slowest run. You should set wattman to max fan targets and then hop into the test.

Since it'll throttle before fans kick up. Setting max fan will keep hot spot below the 88C limit and let it run max speed continuous.

Plus it gets faster the 2nd, 3rd, 4th run. So run it multiple times saving each score and post the fastest... Or post showing how it speeds up.

Running those ones you just made right now brb with results.

OK I haven't been using wattman at all I just set fans to 100 in afterburner and apply that's all I change.

Wattman will more accurately state max possible rpm and also log it so we know for the BIOS... haha cool dude

As long as you leave it open minimized you can check the clock stability graph, it has useful information.

OK here's results run 1 with afterburner



run 2 with afterburner



run 3 after you told me about wattman closed afterburner




run 4 fresh reboot to make sure afterburner had no effect on wattman so i never started afterburner applied settings in wattman

Haha nice man great results, astounding haha Glad to know it is getting faster over time... gotta run it a couple times

One thing I noticed is fan only going to 2669rpm. If only we could run the positive negative gpu fan wires to 12v and monitor the rpm when using the psu direct, could probably squeeze out another 200 points.

Actually using an external 4-pin molex adapter with a nice static 13v input, we can rev the fans up over 3,000rpm and clock 100mhz higher.

Since I know we saw near 2,800rpm or more before. That's great though.

Looks like on the 4th run it finally was peaking on it's big end in top gear haha Noice.

I'm on one Xeon since with my 2nd Xeon riser I can't boot the system. So I bought "Contact Cleaner" to clean the memory slots/ riser pins and hopefully getting them both chiming on all cylinders soon.

To see beyond 15,800 gfx I need at least 2,100 total frames on Test 1 & over 2,600 total frames Test 2.

On Thermagon T6100 I am 10-20fps lower on the "High End" fps spikes in Test 1 & 2. Where on Thermeez I would near 100fps spikes in parts of Test 1 & 2.

On Thermagon T6100 I see barely 90fps "Spikes" on Test 1 & 2.

Basically the more Exotic the thermal material used, would see more "Freak" fps spikes in Test 1 & 2. Those "Freakish" FPS Spikes is what I count on for max scores.




That took a while but finally we are on the same page now. You are on 14800 graphic score range on preformance presets which is exactly where it should be. As i thought, 15800 graphic is a custome run result. Please stop telling to users that you are scoring around 15800 in Firestrik as it is misleading.

I was trying to reproduce your clocks on my card and run firestrike and my score is almost identical, i saw in your posts that your card is operating on 1407-1416 MHz, so i choose 1410 which is more or less in the middle. I saw that your memory is set on 2267, i use uber V2 timings and my memory max out to 2100 with few EDC errors and i set such clock to the test. Firestrike do not benefit a lot on memory actually it will increse the score by 100-200 graphic points. Let sa that RX 480 is a mid range card and CPU do not limit this card.

As far as i know your are using old drivers 16. 09 or 12 i dont remmeber, these drivers boost a bit FireStrike score, I was using latest 17.3.3.

Summary: 1410/2100 with uber V2 timings.

Time for magic: 14727 Performance Firestrike comparing to your 14801

http://www.3dmark.com/3dm/18950731?

So, let's validate the statements which i saw in your posts which to be honest were stonishing for me:

1. You said that using some exotic thermal compound on VRM will increse FPS - BUSTED - my VRM is burnning and i did that to prove that your statement is false, VRM temperature is absolutely irrelevant before you reach the threshold of 115 C degrees and you will find such information in this thread in other posts as well. This is the way how VRM works. You can improve thermal conductivity and maybe lower a bit power efficiency and work culture. That's all, for sure it will do not impact FPS in direct way.

2. You said that cooling of some cold chips on the PCB has extended your performance capabilities - BUSTED - irrelevant for performance, i do not have any heatsinks on mentioned chips, most of them are cold, no impact on FireStrike score.

3 . You said that you have scored 15800 in Firestrike performance run on ~1416 core and 2266 mem - BUSTED - score do not lie, usually smile.gif The real score is around 14800 points and it is very predictable score. Bare in mind that on core set 1410-1420 and dicent voltage around 1.21-1.23 your card will start to exceeding power budget = power throttling. If you didn't extend the power limit in bios your card will slightly throttle due to insufficient power budget,

There is no reason to romanticize RX 480, it's a very good card in resonable price range. There is no need to falsify the results of this card.

I'm open to discuss about above, if you can proove this mistical 15800 graphic score i will be very interrested to have a look on that.

Thanks for the score, you can enter the link as well, then we can have a look on the overall setup.
