Hi guys,
Ok, This is the scenario... Please bear with me.
Since buying my 7970's I have been constantly testing and battling with OC settings, with my cards not liking to run over 1050 on the core regardless of voltage used. As soon as I try 1075 or above...BSOD 116.
Whilst i realise that on overclock is not guaranteed, I have discovered something interesting that proves in my case, its not just poor cards... read on.
I have 3x 7970's now, and recently tried swapping cards around to see if it made any difference and made an interesting discovery...
No matter which card I use, the one connected to the 3 monitors is then limited to the 1050 core.
This led me to trying different overclocks on each card so they are no longer tied together and, low and behold, the other 2 GPU's will run much higher core clocks!!
So, I made an assumption that since the card running the 3 monitors is also the one getting the hottest, i would await until I got my new loop installed and expected that the lower temps would solve the problem. Sadly, I was wrong.
My max temps on GPU and VRM's are now 40C and still the same core limit of 1050 applies to any card running the three monitors.
So, my question, you guys out there running in eyefinity with 3 monitors, what OC's are you achieving?
Thanks in advance for any info your can offer.
P.S: I realise that my next task is to disconnect 2 monitors and set the software up so its running just the one.
