1133 first then 1172mhz ..

Send your Screenshot here of HWinfo temperatures

Run it through Time Spy & FireStrike

I can see in powerplay that made several changes but you downclocked the RAM params freq, the GPU clock 2 and power from 1000 to 875, you also made some changes in the fan profile.. Can you please explain PW Fan max value?

Last, the VRM settings you almost deleted everything in the firmware 1172 MHz??

I'm just learning from you biggrin.gif That's why I need explanations... Learn from the best thumb.gif

I think you confused the BIOS up... Here is your bios again.

********************************************************************
1133.1250.875.1333.zip 43k .zip file
1172.1250.875.1367.zip 43k .zip file
********************************************************************

It's power delimited, zero power limit, I also found ASIC at 57599 as well is a little trick maybe gain a few points, Idk if it's placebo as that ASIC temperature doesn't even seem to work, it defaults to 94-95c

57599 values is the max allowable & yields absolute peak performance...

57599 gives continuous 110,000% consistent throttle-free performance for whatever you wanna use it for. Just makes the card a far better work horse.

390x @

1133mhz = 6.3 Tera Flops
1172mhz = 6.5 Tera Flops

So R9 290/390 would be like 6.2 & 6.4 tera flops... which is barely any slower at all.

Otherwise for the other guy I set 0 VDDC offset .. meaning closest to the voltage set is ideal.. an offset isn't ideal.. we need all the voltage for stability

VRM to 255... just allows peak power.. barely tell a difference at all but I think it helps out the frame rate... It's just a way to get the card running all the way out to it's absolute fastest possible speed possible... That's the way I like it... As Fast As Possible & Stable & Cool.

I altered the states for efficiency & everything in there is edited & pre-tested... I flashed & tested THOUSANDS of different settings finding the lowest/ highest/ most stable voltage per every clock & tested fan settings THOUSANDS of times over so the BIOS is basically a masterpiece of hardwork & lots of testing... Testing testing testing.. I tested it all & it works perfectly

Make sure you monitor your VRM temperature's though.. The core should be Cool but the VRM might be warm @ 1172mhz

Thank you for the explanation specool.gif Can you please tell me what kind of R290X you have?

It's a Reference R9 290X 4GB & I have a 390X 8GB

I just flashed the first firmware, can I ask why lowered the ram freq ?

Because allowed to use 875mv to save 100 watts cooler temps...

Your looking at like 1 frame per second by consuming an extra 100 watts for 1350mhz to 1375mhz...

Test Firestrike, post results & HWINFO

I reflashed the stock firmware, while on ur firmware I was playing overwatch the fans are running like a jet! The stock firmware runs it cool and silent I guess it needs tweaking concerning the fans profile,,

Your gonna hit 100C if you leave it stock. I do it so you don't rape the video card. Check your temps.

If you couldn't tell a difference in performance .. then let it eat & the caps solder will become cold-solder-joints & the card will stop posting... Notorious r9 290x issue & 390x .. hawaii in general is notorious to fail
