Yes, powertune - when it's not configured properly mem-clock will throttle up and down (150-your mem speed).

I also had this issue and after looking for a solution for over a week I managed to fix it by enabling 'Unofficial overclocking mode without PowerPlay support'. I assume of-course that you are using MSI afterburner.
Uninstalling MSI AB might also fix it, or alternatively installing it if you haven't got it.

I made a topic about it a few days ago but no1 responded there; I had an image uploaded there, does it look similar to that? https://bitcointalksearch.org/topic/m.6989373

Anyway, now I got a straight line representing my mem clock speed.

You welcome. This issue bothered me for almost a month now

I can't get my R9 290 to run stable with 5 threads.. Than again 2 threads on 14.4 drivers are getting me 3.98MH/s so it isn't so bad I suppose for ref cards.

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
export GPU_FORCE_64BIT_PTR=1
##export GPU_MAX_HEAP_SIZE=50
del *.bin
timeout /t 4
sgminer.exe -k x11mod --rawintensity 1306624,1306624,1306624,33280 -g 1,1,1,2 --shaders 2560,2560,2560,1280 -w 256,256,256,64 --thread-concurrency 24577,24577,24577,10241 --no-submit-stale -c sgminer.conf

My 290 also is jumping memory down to 150 and back, do you have any explanation what might be the reason for this behavior?!

Wow thanks for that, it's gotten me up to the 4.05-4.1mh/s level with my 290 tri-x's using my previous config but with 5 threads now instead of 1.

I tried other drivers but 12.13 seems to work best for me on Windows 7. Using the B2_sick version.

The longest I have been able to get my rig to run is 12 hours. I don't know what's causing it, but it's freezing up and I have to do a hard reboot which isn't convenient since I normally use team viewer. I posted my settings at https://bitcointalksearch.org/topic/m.7036775 if anyone can look at them and give me some suggestions. If the miner was just crashing I wouldn't care so much because that's easy to restart. It's just the hard reboots that are killing me.

I have 2 cards, both running at 1050/1500MHz set with Afterburner (power limit +50). I had to take out the engine and memory settings from the config file as the memory frequency was jumping around between 150 and max setting. Very stressful on the system. Now everything is smooth. I kept only the temp control as I like the strategy.

Hi guys, thanks for your work. It took a while to read all the posts, but I learnt a lot. I have just broke the 4MH - X11 barrier for R9 290 (ASUS R9 290-DC2OC).

Here are the settings for those interested:

GPU threads have been increased as to flood the memory as much as possible with mining work (5 seems to be the max limit for my system). That was a tip on the forum as well, thanks the author. Cards memory is now loaded on >80% and my RAM as well.

The miner is Elun's b2 version from the OP, drivers 14.3beta, Win 8.1.

Out of my 2 cards one is water cooled and I guess it can go higher. I'll upgrade the wc sytem in a couple of weeks (have to raise more coins and then go for 5MH/card. I hope I can get there.

When I started reading this post, 2 weeks ago, I had 2.5MH/card, then raised it to 3.6 by following you advises and now 4-4.1. First jump had no impact on energy consumption. Now, I estimate a less than 5% increase, which, for me, is acceptable.

Thanks again guys for your work.

i don't think you need to specify the same settings everytime, if you use only one type of gpu
