Yeah that's a good point, I have adjusted some settings and get about 850 k/h @ 80c. It's not maxing the card out but then again I can at least mine 24/7 with reasonable temps.

I think what went most of the way towards solving the problem was trying your suggestion of powering everything off completely, this helped me to realise that my card actually did work if only for a second. I then tried putting much less stress on it (by taking the intensity down to 13) and working my way back up from there.

I have the MSI Gaming OC Edition with the twin frozr cooling and I'm currently using the following in my batch file:

cgminer --scrypt -o stratum+tcp://stratum.netcodepool.org:4093 -u user -p pass -I 20 -T

My core clock was being throttled for a while at 850mhz @ 94c but I've since moved the pc downstairs which is much cooler, now I can get the clock up to 950mhz @ 86c without much problem. I'm hovering around the 850 k/h figure right now but I feel there's more to be had out of it yet with a bit of tweaking the config. Unfortunately that's where my skills fall a little short.

Also I'm thinking of moving that machine out to the garage tomorrow which I've read other people have done without issue, the rather chilly UK weather should drop the temps another 5-10 degrees which should allow me to go up to or maybe above 1000mhz core clock.

Thanks for the tips, I shall give those things a try and see how I get on.

Update: I seem to be getting on ok now, not great but 800 k/h. I started with 1030mhz and intensity 13 getting me 500 k/h, I then lowered my gpu clock to 950 and upped the intensity to 20 getting me 800 k/h. Not sure what I can do next but I guess there's going to be a lot of messing around to get the kind of speeds that others are seeing with their 290Xs.

Thanks to everyone for their input, probably would have given up a while back otherwise.

Ok to try and answer some of those questions, firstly my specs are as follows.

Machine 1:

i5 3570k @ Stock
z77 Sabertooth
16gb RAM
Xigmatec 700w psu

Machine 2:

AMD Phenom 2 X6 @ 4ghz
Asus M4A89TD Pro
8gb RAM
Corsair HX650

The 290X is currently in the AMD machine plugged directly into the board (don't have a riser) as I had no luck in the Intel one, I've been trying this with the monitor attached as when it's not the card shuts down so I need to make a dummy plug at some point.

I've tried with 13.12 WHQL and 13.11 Beta drivers on both windows 7 and 8.1 and still the same issue, I've also been installing the AMD SDK 2.9 as someone else told me I needed. Something strange happened on Windows 7 however, to begin with it would actually boost the memory clock up to the correct value but the driver would crash after like maybe 5-10 seconds. Now for some reason I'm back to the old problem of being stuck at 150mhz.

atp1916 I wish I was using cgwatcher and that was the culprit but I'm just trying to run this using a batch file. I've tried using the config method but I'm getting an error that reads "cgminer: --config: JSON decode of file 'mine.conf' failed.

sighle I actually tried the method of switching everything off and draining the power which seemed to get the card working again for a brief period of time before the AMD driver crashed and now I'm back to where I started.


Seems to be that the card will actually work briefly before the driver crashes and then I'm stuck at 150mhz until I power off and start again. I guess I'll have to try and find a config that doesn't stress the card too much but that's going to be quite difficult as I'm guessing the defaults aren't maxing it out.

Same error I'm afraid, I'm at a loss to know what to do next. Everything that works fine for others is just not working when I attempt it.

I've tried that but unfortunately I get the error

The different errors are me trying to save it in ANSI and Unicode after notepad complained and then I tried with notepadd++



I'm actually on a fresh install for the 3rd time, I will try just the drivers again to check, are there any preferred versions I should be using. Also which version of AMD SDK should be installed?


Thanks for everyone's input so far.

setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100

I've tried so many different configurations that I wouldn't know which to send, did start with this one however and modified it accordingly:

setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
cgminer --scrypt  -o stratum+tcp://stratum.dogehouse.org:3334 -u Weblogin.WorkerNAME -p Worker password --failover-only -o stratum+tcp://stratum3.dogehouse.org:993 -u Weblogin.WorkerNAME -p Worker password

I've tried forcing the gpu clock and fan with the batch file and that works but trying to set the memory clock through there doesn't. I'm also using this on a fresh install of Windows 8.1, not sure if that matters but I'll include it anyway.

Hi guys, I'm absolutely at a loss with this one so I'm reaching out in the hope that someone can help.

Basically I've just bought a MSI 290X Gaming and am having issues getting it to mine, hopefully it's something I'm doing wrong but I'd tried for hours now with no luck. As the topic title suggests the memory clock seems to be stuck at 150mhz when I try to mine anything giving me around 17khash or something stupid, I've seen many different numbers but nothing over 70.

The core clock goes up to the normal max (1030mhz) and so does the memory clock (1250mhz) while gaming, when attempting to mine however it just sits there at 150mhz. I've tried forcing the card to stay at the standard clocks but it still gets the ridiculously low hash rate.

Well there's my issue, hopefully one of you smart folks has seen this before or something similar and can show me the error of my ways.

Thanks
