MSI R9 280x Gaming 3G Miner settings

AcidD

Hey Guys,

Background: For the past three days 1 of my miners has been acting up, it crashed in Windows 7 x64 and then never seemed to recover. My hash rates dropped 220 per card…

4x MSI R9 280x Gaming 3G
Corsair AX1200

4GB RAM

I tried:

Updating the Bios’s on the cards
Cgminer/SGMiner/ with different kernels.
Screaming
other things that I cant remember off hand.

What I have done now is formatted and put windows 8.1 x64 on. with the AMD 13.12 drivers…so everything is nice, clean and new.

I’ve come across this article:
http://blog.truepps.com/r9-280x-optimal-scrypt-mining-config/

and those are the only settings that work and are inline with the MSI R9 280x hash rates I’ve seen on other forums/sites. Most people say if you get the GPU-engine between 1020 - 1080, thats the sweet spot for these cards hitting 730+ Kh/s

What happens is every time i change the stock engine or memory from 1020 and 1500 (respectively) - my hash rates drop to around 500 Kh/s per card.

using the above config, I can get my hash rate to an insane 770+ and it seems pretty stable…problem is I’m worried about the heat…see the screenshot below.

I’m super worried about the temps, leaving it like that for 15-20 mins means the GPU 0 hits 90c and all the cards perform at 799 KH/s.

I’ll I want is for each card to hover around 750 KH/s and that should give me a temp of around 75-80 on max load, which I am happy with. I have a desk fan blowing from the back of the rig and it’s all open air, so I dont think cooling is a problem.

I just need help finding the exact settings for GPU-Engine and memclock in order to reach 750 Kh/s

Edit: I’m a poor miner, but if someone does help me fix this problem I’ll send 1 days worth of FTC mining to whatever FTC address you give me.

Dude I don’t want your money, your settings seem good for a 280x, I’ve never seen the memclock so high.

What’s the exact hashrate when you go memclock 1500, powertune 10 and engine 1050?

Hey Dude, I’ve managed to sort the issue.

What I ended up doing was not using any clock or engine settings in sgminer, and adjusted the clocks/engine in MSI afterburner. I guess that + the new reformat + win 8.1 + fresh driver install, seems to have done the trick… Now doing a clean 745 KH/s with these settings.

MSI Afterburner settings is Gpu-Engine 1080, Mem clock 1500, I also undervolted the cards, so According to MSI they are running at 1.000mV

Now thats what im talking about…
