Core clock remains stable at 1342 MHz under sustained load; I haven't attempted any OC yet. This is in a Corsair 250D, I imagine a larger case with more airflow would give lower temps.
Oh man, the BF1 default config is so clumsy, are there no door opening sounds yet?
How do I enable DX12? I can't find it. It is not there where it should be in options.

BF1 and Doom seem to run cooler than Evolve. Maybe 2C lower and 100rpm slower fan. I have stock clocks same as reference for now, BF1 DX11 no problem 1920x1200px, I may run Fraps stats later or something to get average but so far I've seen 80-100+fps or so.

Slap me, I'm still on Win8.1 in the process of moving to Win10 so of course the damn M$ doesn't support DX12 below Win10. Gorram it, devs stop using DX and use Vulkan ffs. No DX12 for me now in BF1.

Anyone knows how to extends the core voltage range in the new MSI Afterburner's beta? I can only decrease 96 mV the core and it's perfectly stable. I wanna try something lower, as the temps are better.

Exhaust from the heatsink is directed out the case and towards the power connector, it's a good idea to make sure the internal exhaust isn't being fought against with case fans for this reason.
I disagree with the Nitro cooler design. The backplate as usual seems useless cooling wise and the only contact it has is with VRM backside:

Look at the GTR bottom, now that is a proper opening for exhaust, sure quite useless at bottom but if it was on top like that on Nitro it would exhaust much better.

Pushing air out the case and to front around the power connector is quite difficult for coolers.

If you look at the MSI Gaming cooler, they finally got it right and as such their cooler is usually the most efficient, it has a lot of open space all around the heatsink, top, bottom, back, all the sides and you can see the heatpipes which are the only thing blocking air.

If I keep the Gainward 1060 I'm tempted to go dremel on the plastic fan cover or make a new cover... if only I had a 3D printer biggrin.gif

Yes, if that is the LED and it's simply wired and stuck in the plastic cover you can discocnect it as seen in picture.

Having owned both, the Sapphire is better. You underestimate the value of simply having air movement over the PCB. The GTR backplate does get quite hot - and if you add airflow you can drop idle temps and VRM temps quite a bit... but as it stands, the Sapphire provides that airflow - the GTR does not.

Yes it is. I thought about blocking off the outside half of the fans and using only half of the flow region to see what impact that would have on temps. Maybe the Nitro+ would even be better with just one fan. I had to return mine before I was able to get too deeply into its physical cooling.

Yeah, I would like to redesign the XFX cooler some as well. Probably will take it off after I do a full series on its temperatures and fan speeds and apply some new TIM. I also have high performance thermal pads I might use - but XFX already used the same kind on the VRM, so it would just be going on the memory.

Why did you swap out from Nitro to GTR?

The Nitro I had would get repeated no video on boot situations - even while the system was working fine... seriously, Windows would boot, but no video output would occur. I would shut down the system using the Windows keyboard shortcuts.

The video would cut out sometimes just sitting at the desktop, and a couple times in game. Kept getting worse. When I installed the card into another computer to see if there was something strange with my computer not allowing the memory clocks to actually work the problem happened two times in the span of thirty minutes. So I RMA'd it.

I then stumbled across the XFX RX 480 8GB GTR for just $17 more than the Nitro+ 4GB RX 470... pretty simple choice thumb.gif
post #1150 of 4143
This Powercolor RX470 makes no sense.

I saw that a new driver was released...so I broke out the card again. I ran a few benchmarks using Wattman and the new MSI Afterburner Beta.

I just made a few runs of Firestrike, and I get some odd scores.

Here is a screen shot:


The first 4 runs are at the stock settings with just the power raised to the max(+50). The last two are with the core OC'd to 1300. My score and graphics both take a big hit.

Any reason as to why?

The first one at 1300 was ran using Wattman. The second at 1300 was via AB.

Strange....to me anyway.

EDIT: Used the same settings...took the memory to 1850....lower than the last one by a little:
