Kind of a Newb question about GPU crashes
-
Alright so I’ve been mining on a single 7950 for almost a year. And I just always assumed it was normal, but, my uptime on the GPU is random and it will eventually end up in a crash. When it crashes, screen has no signal although the PC itself is running fine.
I’ve tried a bunch of different settings over the time, and undervolting seems to extend the uptime [-10 in Catalyst]. Range for uptime is anywhere between 24 hours to 4 days.
Questions:
1. Is this normal?
2. Is there a way to address it if it is not normal?
I’m running GUIMiner Scrypt [yes, yes, I know CGminer is best], but running CGminer slowed my system down tremendously and I’d still get crashes.
I seek your wisdom Feathergeniuses…

Post your settings mate and let us have a squiz…
Screen going blank **normally **means you’ve clocked gpu memory too hard.

Hey, here’s the settings:
Card is running Stock with -10 Powertune
Thread Conc: 21712
Vectors: 1
GPU Theads: 1
Worksize: 256
Intensity: 17

Shaders on that card is 2048, so I’m guessing a 280x is a rebadged 7950. Most people run 2 gpu threads, Thread Concurrency 8192 and Intensity 13.
I’ve also heard that GUIMiner is unstable and is prone to crashing quite a lot for no good reason, I would run CG Miner if I were you… You’re system slowing down would be settings related, so you could de-tune your settings if you wanted to mine and use your PC at the same time.

I’ll give these settings a whirl - thanks!

Use Memclock 1500 and Engine 1050 to begin with, it will slow your system down so if you need to use your system whilst you are mining, try Memclock 1425 and Engine 950, that should give you a bit of room to play with…
