post #1461 of 4152
Today I take a little time to play with voltages and find a nice sweet spot for the RX 480 reference.-
In my case with a Maelstrom 120K AIO water one per video card.-

Core: 1390 Mhz
Mem: 2160 Mhz
Voltage Core: 1.175 (Real 1.170/1.178)
Voltage Mem: Stock

GPU Temp: 60º C
VRM: 74º C

Bios: Unlocked Air Bios from der8auer

No memory errors, in single or CrossFireX.-
Very recommended overclock setting with a nice equilibrium of performance, voltage and temps - For example I need to put 1.20v more or less to get 1400 mhz, that 10 mhz of difference need for me a lot of voltage and the VRM and GPU get very hot unnecessary - The mem freq more than 2160 Mhz give me some random memory errors in HWinfo but this can vary in every video card, usually 2130 to 2170 it's the safe zone without memory errors.-

About the CrossFireX make sure the two video card have the same voltage in Wattman, in my case Wattman detect one video card by default with 1150v and the other with 1100v in stage 7 - So in MSI Afterburner I need to put without sync the settings of video card's and set manually another % of voltage for the second card to get the same final voltage - Its probably something related with the motherboard or something like that.-

Another thing I discover the performance with low voltage and high freq like this setting, it's everything more smooth - I mean the FPS are the same probably with 1.175v or 1.200v but the movements and the image looks more smooth and faster, probably it's my imagination but I read something here about another person who see the same.-

All this with the last Driver 16.6.2 in MSI Afterburner disable ULPS and the voltage control put "Reference Desing" with the "Standard MSI" the MSI Afterburner sometimes get freeze.-



About the picture the Black fan it's only at 1100 rpm to get VRM cold and the AIO Water fan's are controled by every single video card with a custom fan curve in MSI Afterburner no more 1400 RPM - Very quiet and low temp's at full stress.-
The Video cards have the original back-plate to refrigerate memories and VRM with a few minor cuts to make space for the pump near the core.-
The Maelstrom 120K pump of course with a nice zip ties biggrin.gif

And by the way make SURE all the are around the center of the GPU have electrical insulation for example the black insulation tape because I discover (with a lot of luck) the pump cover all the place and touch the little electric components and start to have power draw issues and rare sound in the water pump probably interference, I have the luck to not frit any part of the video card - In the normal desing the cooler have a crest in the center to only touch the GPU center, in this case it's the same so take care about that with a little insulation.-

Yeah the only reason i got it was it was the only one that had no warranty stickers on the heatsink screw that I could get my hands on plus it had dual BIOS. Also I overclocked my two cards and it's been fine heheh

Hold up. I need to put some kind of insulation or it'll have problems? Or is it just a sometimes you need sometimes you don't?

My recommendation it's do it, if you put a "plane" water pump, because you never adjust exactly in the same way the 4 corners (for example it's imposible in my case with zip ties) so you can touch one of the components and have problems, the center of the GPU will be always good dissipated but the pump its very big and can touch some other things, it's not harder to do and you can avoid a big problem.-
I Discover this with the second video card when I put the water block have a lot of problems in performance, electric noise, power draw issues, black screens, reboots, and say... "crap man, I make the same things and this it's failing", then I put the insultation just in case and discover all this.-
Why not fail in the first video card? Noob lucky - Well the first video card I pay more attention in the position of the zip ties so probably it's more straight than the second one.-

Hmm I see ok...seeing that I have no issues with my two cards I think I'll leave it at that. I'm also using zipties btw hahaha

Jaja ok if you don't have problems, don't pay attention, but if you someday change the thermal paste or something, do it, don't play with your luck padawan.

Hahah yeah I will remember that but I don't think I'll be taking them out anytime soon it was a pain in the ass to put in this cramped case.

Any idea how much you score with a single card?

Good, I will do the test probably this night (Argentina) and compared - Just in case tongue.gif

From my POV the stock cooler is flat too so there should be no need for a raised base like pre2013 Tahiti. Sure if the components around are tall it's not the best design choice by AMD :/

But hey at least it's not worse than this, so one last time, the Powercolor 480 sucks and here you go again why it is so:



Here is the rest of 480s:

I have games to review,test, and play so a solution is needed quickly.

Not sure If I will keep the RX-480, since I'm pretty sure my R9-290 underwater will best the rx-480. I plan to find out for sure though before deciding which card to keep. May even buy a waterblock for the RX-480 which is why I picked up a reference card.

I'm not very happy that my other card died again, and in short notice. Pushing 4k isn't easy, and I would like a faster card, but paying 600$ for a 1080 aka a midsize die gpu is a hard sell. I wanted to hold my cards till Vega, or 1080ti. Oh well maybe rx480 crossfire watercooled in my future, *shutters* crossfire. Eh rolleyes.gif

My 2nd reference card is also a asus rx480 reference card. The voltage defaulted to 1150mv at 1266mhz on that one. Card works a lot better at 1068mv. Just an fyi.

Edit: fixed typo and I should also ask. I get a blanking screen during login on that card but not on the sapphire reference card as my display card. You see this? I'm going to crossfire the two cards but I'm waiting to figure out some of my single card issues first.
