Hello all, been trying to get my crossfire setup working but seem to be running into a few issues so finally decided to seek help. To cut a long story short I'm having problems when trying to have my system overclocked, I first noticed an issue when trying to run some benchmarks, I would get system hangs/freezes and (more frequently now in game benches) "amd driver has stopped responding and has been recovered"
Lets see where to start, after my first few freezes I began to suspect that perhaps my cpu overclock may have become a bit unstable so I decided to run it at stock half way through my experimenting, (and while it seemed to solve the issue initially it didnt really last long) and Ive about 2 pages of results written down as I ran benchmarks (small note book dont worry), basically - can running 2 gpus effect each others overclcocks? See my first 7950 ive had for about a year Ive been running at 1200/1425, and it's really been put to the test with no issues, my more recent 7950 was able to hit 1175/1575 and I managed to play the whole way through bioshock infinite and about 6-8 hous of simcity at these settings without issue and pass firestrike+extreme, when I was able to get a capable PSU I obviously loaded them up in a crossfire configuration and after some testing running both cards at their max settings didnt seem to go well (my first benchmarking was done with fire strike only and I must have fluked my way through that as Ive had issues ever since), now when I run Heaven 4.0/Bioshock Infinite/Tomb Raider half way through the bench I get freezes or as stated the "amd driver has stopped responding" (I do have a few results where the bencmarks did clear but I also have a lot where they do not),and this is while running both cards at the same speeds (in case it was this causing issue) - I was running at 1175/1425 on both cards (downclocking the core on 1 and the memory on the other), Ive got my cpu at 4.6 atm as the stock thing didnt seem to work (running whole system at stock did work, but running cpu at stock with overclocked gpus gave me the same issues as before), I decide (before writing this) to disable crossfire and run the benches with 1 gpu - and had no issues with tomb raider or heaven 4.0 (suggesting also that my cpu may not be the cause)
temperatures arnt an issue btw as Ive kept an eye on them, at max low 70s for my cpu (and at max 59-62 when running at stock
have to give a thumbs up to the havik 140 their) and at max low 70s again for my top/master gpu, a bit cooler for my 2nd/lower gpu, so it looks like the maximum overclocks for both cards are reduced when in crossfire - I have a 1150/1400 on both cards (cpu was at stock for this 1) bench down in my notes as passing heaven 4.0 - can running in cf really knock that much of both the core and memory clocks? Or am I doing something drastically wrong?
Any suggestioins? Any questions for you? Thanks for having a read through what I now realize is quite a messy post
