Polaris Bios Editing ( RX5xx / RX4xx ) - Page 170

post #1691 of 3315
Trust me 99 errors, isn't a lot but I guess if we or you would much rather see 0 errors haha try this bios

By way way reason I say that isn't a lot since I've seen way over 1,000,000 errors to 1,000,000,0000...

So 99 isn't much haha

I wonder if your ASIC goes up with 1033mv memory? here are these two... 275GB/s memory 2149Mhz

Jeztur2003_1320mhz_2149Mhz_1033mv_86C_88C_86C.zip 110k .zip file

Your Total Crossfire Throughput of both cards is...

84 billion 480 million pixel's every second
380 billion 160 million texel's every second
&
550GB/s combined GPU memory Bandwidth... Not bad

If you bought reference 480's from Visiontek and ran 1407Mhz core & 2266Mhz memory

90 billion 48 million pixel's every second
405 billion 216 million texel's every second
&
580GB/s combined GPU memory Bandwidth

That's about 6% haha not much but it makes a difference for sure haha

Oh that's no good haha maybe timings are cutting out? Usually that won't occur on regular timings, just tons of errors.

Let's increase memory voltage and try 2188mhz... on default timings... you were down to 9 errors anyway, at 4GB usage... it's best to throw 8GB load at it to see the real error count...

It's not always ideal to do this actually but if it helps then were good... haha 1067mv memory voltage stock timings 2188mhz.

imc voltage in polaris is 1000mv. just use wattman to change it.
to change the mem voltage you need a hardmod. Stock is 1.5v

Yeah if you use the right HWInfo v524 on 16.9.2 it will report the VDDCI at 0.900 on all Polaris cards...

VDDCI is the true integrated controller, the memory voltage in polaris bios editor is the module voltage for the memory VRM.

We can't change the actual IMC on these cards except in hex like on Tonga... which is pretty nice it's locked static at 0.900...

Since Tonga would increase the VDDCI with the Core voltage as an offset... too much vCore would call on way too much VDDCI and cause instability... Unlike Polaris.

Everything past Tonga fixed the issues Tonga had with it's voltage increasing VDDCI if changing 65288 value.

For instance Hawaii and Grenada had it "static" locked as well. Though on Hawaii/ Grenada the vddci was a major culprit of far too much power consumption and heat... ie VRM near 100C. Reducing the VDDCI was locked in 1:1 with IMC and VDDCI for memory VRM so it was very stable as low as 888 millivolts from 1000mv. Not to mention since they were locked together IMC : VDDCI, it made a huge impact on power consumption and heat since they were combined (1000:1000 vs 888:888). Which reduced it's total power consumption and VRM temperature equally as much. biggrin.gif

Basically that reduced all the VRM, the Core, and the entire cards power consumption and temperature by 12.61%... max temp 90C to 79C without touching anything... Although I modded mine and sped it up so temps were different. If left stock voltage power limit, it would drop that much.

Fun stuff, I learned all this from Tonga. Tonga taught me so much about these cards since they all carry the "same" stuff. That "same" stuff just behaves more appropriately in later tech newer cards.

hey chris this is with the 1320 2149 1033mv only 2 errors

Try 1000mv the other one and see how many errors so we know if we need to go up in voltage or leave at 1000mv or go below 1000mv haha

If we find that out, and get the error count. We can globally know what to do for errors for everyone. thumb.gif

By the way if you notice GPU 2 @ max 1.250v that's amazing... The GPU is so intelligent it knows it's not pulling 75w from the slot... it's probably pulling literally 18.75 watts from the slot since PCIe slot 2 is wired to x4 right?

So it's making up for the loss in Slot Power Capacity via extra power from the PCIe power pins... Interesting for sure.

Here's the results and scores on benches are impressive.

Nice guys and nice results jeztur, no errors! haha 1000mv?

Yeah generaleramon : VDDCI is an offset to the core voltage of 65288, 65287 etc... in the 02 FF like stuff. With the XX FF etc and so on

Basically it's static though so messing with it probably isn't ideal, its not tonga after all.

Just so you guys know if you ever wanna mess with it focus on 65288 only to start if wanted... not needed just fyi.. but as for Tonga.

It went like this I think the stock 65288 offset in hex was value -50 basically 1225mv vcore to 1175 vddci ... = -50

in hex it was that but actually in hex you add or -1 so it's -51 ... Decimal to hex is CD FF ... the calculator will say FF CD but you flip it...

So for Polaris we can see from Jeztur the true max 65288 voltage is 1.250v ... so basically it's 1250 - 900 = -350 so -350 add 1 for -351 decimal to hex is FE A1 so flip it for A1 FE...

Would need fiddling but that value is what would be found in bios if bios is set to 65288...

As far as Polaris goes ATOM BIOS READER doesn't work properly and data is pretty well invalid. We can take this as a "Shew" that there's no need to hex mod the Polaris. biggrin.gif

Maybe somehow Hex-mod out the sensitivity would be the best thing so the fan actually abides by the min/med/high/max temperatures, rather than soley PowerTune.

I suppose though it's best left as is... Unless we could some how "Fix" sensitivity but I actually find it to work fine for what it does if found the ideal Sensitivity value... Anyway haha

By the way I did find the ideal sensitivity value so were golden.

yep that's the 1000mv and I'm currently getting over 40fps in ghost recon 4k! Had to resize image as it was over the 10mb limit

So I really like these latest bios and no errors in crossfire so thought I'd test a single card to check performance and got about 27 errors strange right? Runs like a dream though single card or in crossfire.
