MSI R9 290 overclocking (esp voltage)

Hi all, as I mentioned in another post I've really enjoyed reading these forums since I discovered them a couple of months ago. I purchased an MSI R9 290 Gaming recently and love it, after a few teething problems with drivers etc.

Having spent some time tinkering with it for maximum performance, I was hoping that based on the info I provide, others might be able to tell me whether I can squeeze anything more out of the card? I'm now assuming the rest of my rig might be holding it back slightly.

For example, I can only overclock it to ~1050mhz core before it starts getting a bit dodgy, and I've been avoiding upping the memory clock as it definitely starts crashing etc when overclocking that, for not much gain. I read from LtMatt that if I did want to overclock the memory increasing the voltage is a must. But for some reason my card just won't co-operate changing voltage. Firstly AB will change whatever I input (eg if I put +50 and press apply it will change itself to a random number like 21). Secondly if I do get it on say +50 and overclock the core (and memory), it will black screen me mid game, with temps only around 73-75. I mean when I mine overnight at 860kh/s the temp hovers around 85 so I know it can handle it.

Also, mining is all done at the MSI default 'OC' mode at 1007mhz core and 1250 memory, anything more and my kh/s go down. Anything more than intensity 18 also lowers kh/s or crashes the system. So this is where I think my rig is slowing it down, my specs are below. If you need any more info let me know. I'm considering water cooling for the GPU but whether or not it's worth it? I feel like this thing has heaps of power but is held back by heat, even with the Twin Frozr cooling, which is pretty good and looks awesome. :cool:

If anyone has any advice for me I would be most grateful! Cheers guys!

MOBO - Gigabyte Z68XP-UD3
CPU - i52500k @ 4.3ghz (closed-loop water cooled)
RAM - 8gb GSKILL 1333mhz (2X4gb)
STORAGE - system is on 128gb Fujitsu SSD
data is on 2TB Seagate Barracuda 7200rpm with a 60gb Corsair SSD as a cache drive for the Barracuda (works awesome)
OS - Win 8.1 pro
 
Are you using the latest beta 18 of MSI afterburner? Your card should be capable of doing around 1050-1125 on stock voltage, which is 0.000v+ in afterburner. 1050 is a good place to start and take it from there. If you get a crash or artifacts just bump voltage two notches (0.012v+) and try again. Once you're happy with the core then you can experiment increasing the memory. Do one at a time so you can pinpoint the cause if something goes wrong. Get rid of the MSI app, if you have it installed.
 
LtMatt other option is hes card is ****** clocker like one i got. Mine was artefacting on stock voltage at 1060mhz....

Could be. However unlike Tahiti on Hawaii you cure an artifacting card by adding more core voltage. My card artifacts at 1000 core if i starve it of enough voltage.
 
Yes I'm using the latest AB, beta 18. That MSI Gaming app, whilst I know it's a bit pointless when you have AB, for some reason when I'm mining it pushes me up to 860kh/s on OC mode art 1007mhz. But if I input 1007mhz into AB and apply, I only get 840-850kh/s. I feel like that pointless little app might be making a small change to the bios or something...but not sure.

But I will delete it, and try to up my voltage in small increments and let you know how I go. Forgot to mention in my OP that I have a CoolerMaster 650w PSU, that should be plenty for my rig yeah? Cheers
