It's all good? What do you guys think about my XFX RX 480 8Gb reference.

Nice. thumb.gif

What is everyone's opinion on the reference XFX 480? Seriously considering it, as have a 470 Strix right now, and too much warm air accumulation in my case under both GPU & CPU full load (S340). Airflow is optimized with case fans, so no improvement there. My 470 has a 84% ASIC, so hesitant to change if these reference XFX's have lower ASIC's, and seem to have worse voltage scaling. Still, cooling on the 470 Strix is far less than optimal...

Nice Overclocks Bros thumb.gif Yeah ASIC also has to do with the quality of the input power. Meaning the power from the PSU through the PCIe slot and the 6-pin. Lower Quality PSU gives less ASIC like mine 70%. I haven't tested on good psu yet with idle 12.5v through PCIe slot and 6-pin. The Reference RX 480 from Visiontek can do 1407Mhz stock voltage. It can do 1466Mhz on 1233mv with fan speed.

@Beat Is Ellesmere the original Sapphire BIOS that came on the card, or the RX470_Original? It's always best to use your original bios that came on your card buddy biggrin.gif. You never want to flash a different Card's BIOS to your card. That always screws everything up with Device ID's and what not in the card.

So it is Ellesmere?

I have the Strix 470 too, and IME the 60c target hard coded into the BIOS really shafts the card's performance. A lot of ppl complaining that it is faulty because of this, but it's really just the absurdly low throttle temp. Almost positive that with delimited BIOS and re-targeted temp, card would behave flawlessly. Or, it could be that the VRMs are just not high quality, but I doubt it.

1407 MHz @ stock vcore is very impressive. I'm going to have to go into the BIOS and reset everything to see what it can do.

Polaris is reminding me of the 5850 & 7850, where they would just devastate the next GPU tier above them once clocked into the mid-upper ranges. biggrin.gif

Do you have any recommended settings or a BIOS that I could flash to resolve the issue?
post #1546 of 3471
@btupsx Thanks yeah these cards are good. Only if the power is DeLimited, clock alone can't make it faster. It needs more power to get more work done, ya know?

@Zorgon If you would kindly send me the bios .rom to me from GPUz dump, I can help fix your problem. Thanks

Posted that picture just to show the temperatures biggrin.gif Got an aftermarket cooler and CooLaboratory Ultra on the chip..

Dunno why but the memory clock i cannot rank up to much... Got perfectly stable at 2050 (running almost 1 year whithoud problems 1345/2050)... Tryed that clock at 2100 no errors, but i was playing cs go and got a blue screen... Even give more voltagem, 1100mv on the modded bios.. but... mehhh The gpu clock i can go at 1400Mhz whithoud problems...

I do not recomend Reference cards... Two easy things, noise and temperature.. Only if you mod the cooler like me... My Asic is 80.6%...

post #1548 of 3471
Yeah I hear ya bud but the reference blower performs awesome and isn't "loud" at 3300rpm or so... in the 4000rpm+ range it could be a little loud but that's too much anyway.

On 1433Mhz it can be just fine at 3000rpm which is not loud and performs awesome. It's all about dialing in the ideal fan rpm that sounds fine to the ear and performs amazingly.

Take chris89 up on his offer, he knows what he's doing. I haven't had an opportunity to dive into the BIOS yet, but the fixes are easy. I've dealt with the throttling by settling on lower vcore and ramping up fans much much higher than I want. Temporary fix until the BIOS is edited.

Oh that would be really cool. I am down with either reference clocks or the Strix ones. What exactly needs to be changed?
