I have fixed a few issues on

I have fixed a few issues on Polaris (VRAM amount and GPU Memory Controller Utilization reporting). No other issues known so far, so all should be well.
Here the latest build of HWiNFO64: http://www.hwinfo.com/beta/hw64_531_2894.zip

Thank you, will try it when I get back from holiday on Tuesday if you haven't published yet.

9 valid so far this morning, no invalid or inconclusive. Times are similar to a 7970 at 3x.

Anything after the 3x 1 July 15:04 results should be ignored for time, as I had a few stray tasks I stopped and started, and am letting them finish up before I shut down the machine for the weekend.

On the same i5-4690K host

On the same i5-4690K host which was running a HD 7990 ( effectively two HD 7970s) and Platinum 750W PSU, swapped gpu for RX-480.

Unfortunately the new gpu needs the new drivers (AMD gpupro drivers - not fglrx), which in turn needs a new OS (Ubuntu 16.04 from 14.04). The old card is not supported by amdgpu yet.

Some results

Some observations at x4.

Before - HD7990 Ubuntu 14.04 + fglrx
GPU temp 89C
Wall power 500W (220V)
Tasks being validated ok.
Run times stable at ~9000s
CPU time ~2600s

After - RX-480 Ubuntu 16.04 + gpupro 16.30
GPU temp 79C-
Wall power 235W (220V)
Tasks being validated ok.
Run times stable at ~10300s
CPU time ~580s

and a lot quieter.

One interesting side note is the CPU time, which i suspect is OS change related.

I suspect the drivers and card have a lot of room for optimisation, and i haven't found how to adjust clock speeds on the RX-480. no aticonfig etc.

Sadly the HD7990 is not supported on amdgpu drivers- yet :/

The RX-480 uses only 6 pin external connector (instead of an 8 pin). The 7990 needed two 8 pin connectors. This may be a mistake from what i read in the press.

I have just dropped down to x3 to see where this takes us.

AgentB for clarification, you

AgentB for clarification, you were running x4 and not the x5 suggested by the 0.2 setting from your recent scheduler logs?

I am maybe getting my hopes up but I have a Sapphire RX480 8Gb arriving tomorrow (the cheapest deal I could find) for testing to destruction!!

My current expectation of the RX480 is for 280X performance from much lower power. I don't however expect the performance / power reduction available from the newer NVidia offerings, at the same time I am not prepared to pay the huge premium for a little higher throughput and in real terms arguable energy savings for a crunching card.

Exciting times!

Learn something every day at E@H, i didn't know that was passed in the scheduler logs.

Currently i'm running an app_config.xml which overrides the setting, so you don't have to wait to the cache clears.

It was 0.25 until this afternoon.

I had hopes of it being better than a 7970 for crunching, it's not quite there but it's a lot cooler and quieter than the 7990.

Indeed, there is supposedly a new driver on July 5 to address some of the power issues, i think they missed a trick in using a 6 pin plug.

Point of clarification: use the of the Einstein preference web page mechanism to adjust number of simultaneous GPU jobs takes effect the next time a relevant WU is downloaded after the web page change has been made, and takes effect for all work of that type the moment the download is complete (including currently running work at that moment). So a full cache clear is never required.

I received my Sapphire RX480

I received my Sapphire RX480 this afternoon and have installed in my daily driver perhaps an hour ago. I'm posting far too early to give real thoughts on this cards crunching abilities but wanted to share one or two early observations.

I installed beta driver 16.6.2 direct from AMD a few days ago in preparation for the RX480 so all I had to do was simply install the new card, wait those few moments of black screen hell thinking "oh crap!" and continue crunching from where I'd left off... After those brief moments of panic I am happy to announce the transition completed successfully :-) and the card is merrily working away at completing the in progress tasks I had left and running at my previous x3 setting.

Initial impressions of performance are slightly lower than I hoped but are probably in reality pretty close to the 280 (non X) cards. Future better drivers and some judicial tweaking of clocks may well unleash more oomph.

With the installation of the 480, AMD's overdrive has gone and been replaced by a new utility called Wattman, which at first is less than intuitive but after a few minutes of fiddling I managed to tune the fan speed and temperature targets to achieve my goals. At default settings and a room ambient of 23C this card was sat at 80C which is far beyond my self imposed limit (I run all my cards at 60-65C with an upper limit of 70C but I'm perhaps just over cautious)! To find a happy medium with the reference blower noise and GPU temperature I have set target and max temperature to 74C and fan speed max to a little under 2900 rpm, after that it gets annoying. GPU-Z reports that to be 64% fan speed and a max temp of 72C. GPU-Z also reports core clock at 1266MHz, Memory speed at 2000MHz, GPU load average 98% at x3 concurrency and average power draw as 104 Watts.

Going off at a slight tangent I installed driver 16.6.2 on my R9 390 Hawaii toting machine and removed the config file limiting it to a single task, this card has been running x2 for several hours and I am happy to report 10 valid tasks and a couple of pendings. There are however 4 inconclusive tasks in the mix... Considering all tasks would end as validate error with previous drivers its looking like progress :-)

This is good news, if you do get a run of valid results, might be worth posting to this old thread as there will be a lot of GCN 1.2 cards waiting for this.

Meanwhile back to x3

GPU temp 79C-
Wall power 235W (220V)
Tasks being validated ok.
Run times stable at ~7760s
CPU time ~540s

and sadly a black screen (but still crunching)

I'm back. Did a little

I'm back. Did a little reading when I got home and found someone who managed to get Windows 8.1 drivers working, by manually updating the driver through Device Manager and using the included CD. I now have a beta driver running the card on the Win 8.1 machine. No audio through HDMI yet, though.

It's now doing 3x on an i5-3570.

Eyeballing the first set of 3x has tasks coming in slower than my downclocked 7970, and slower than this card was running on a Xeon E5-2670 with Windows 10. First glance, I'd agree with Gavin, 7950 / 280 level. On the 2670 with Windows 10, it was looking more like a 7970 / 280x. However, I suspect I'm running poorly optimized drivers, given they're labeled beta and AMD hasn't even released them for Windows 8.1 on their main driver page.

Power consumption at the wall (well, at the UPS) is slightly lower than a 3x 7970 on the i5, which has a 77w processor:

7970: 80w idle, 260w running 3x.
RX 480: 65w idle, 245w running 3x.

480 removed this morning due

480 removed this morning due to some strange overnight behaviour. More on this later as my time permits...
