| Processor | i7 6900k @ 4.3GHZ |
|---|---|
| Motherboard | MSI X99A Godlike Gaming Carbon |
| Cooling | CPU/GPU loop with 480mm and 360mm radiators |
| Memory | 32GB Corsair Dominator 3000MHz C15 |
| Video Card(s) | 2x EVGA 1080 SC ACX @ 1830/1330 |
| Storage | Samsung 950 Pro M.2 512GB, WD 2TB Black HDD |
| Case | Corsair 900D |
| Power Supply | EVGA 850W Gold 80 plus PSU |

The two graphics cards that I have in my system are:
Asus Platinum HD7970 Matrix 1100/1650 3GB - Stock core voltage of 1257mv
XFX Radeon HD7970 925/1375 3GB - Stock core voltage of 1170mv
Other system specs:
i7 3770k OC @ 4.7Ghz (Confirmed stable)
32Gb DDR3 RAM 2400Mhz
128GB Samsung 840 Pro SSD
1TB Caviar Black WD HDD
Asus Maximus V Formula eATX Motherboard
My drivers are up to date and my temps during the tests are normal.
I decided that I was going to see how far i could push my GPU's on stock voltage. I started with the XFX card and was able to reach 1100/1525 at stock voltage. To confirm stability I ran and monitored a 10 minute Furmark 1080P Burn-in test and saw no problems at all.
I then moved on to the Asus card. I started with the memory and was able to clock it at 1750 with no issues. When I started with something i deemed reasonable; 1200Mhz. The second I opened Furmark it crashed. I had to lower the core clock to 1170Mhz before I could even open Furmark. When I ran a Burn-in test I immediately got artifacts. I continued to drop the core clock and yet continued to get artifacts until I reached 1155Mhz. So I said "OK" and decided to try and push 1155Mhz with an increased voltage. No matter how high I increased the voltage the clock was not stable >1155. I've spent several hours doing research and trying to find the right combination of the two and have had no success.
If anyone has any suggestions on how I may be able to push 1155Mhz, I would really appreciate it.
