Hi, I am currently working on overclocking my dual MSI R7870-2GD5T/OC cards.
I have a few questions I cant seem to find answers to.
First, what is a "safe" maximum voltage for the core on these?
I understand any overclock is not exactly safe and risky.
Also, I have been unable to find stats posted from anyone overclocking these cards.
I am curious what kind of results people are seeing.
So, getting into the thick of it. I am using MSI Afterburner version 3.0.0 Beta 15 for the overclocking.
I am Benchmarking and load testing with Heaven dx11 on all maximum settings.
Stock settings: Results:
Core voltage: 1219mv Avg FPS: 51.1
Power limit: +/_ 0 Score: 1288
Core Clock: 1050mhz Max Temp: 62 deg C
Memory: 1200mhz
Adjusted settings achieved: Results:
Core Voltage: 1231mv Avg FPS: 55.8
Power Limit: +5% Score: 1406
Core Clock: 1175mhz Max Temp: 67 deg C
Memory: 1333mhz
At that voltage and power limit I can benchmark the core at 1200 and memory at 1380. But it crashes after ten or fifteen minutes in a load test. so I backed it down. in the benchmark it gave me another 1.4 Fps.
I plan on working on raising the memory more tomorrow. Just running out of time today.
Do I dare push the power limit up? Do I dare raise the voltage a little more?
I would like to try and squeeze a little more out of them but I don't want paper weights either......
Thanks in advance for you comments.
