My new Toys!! MSI 7870 Crossfire - Page 5

post #41 of 69
I am so tempted to get 2 7850's the twin frozr ones like you have but 7850 versions. What do you think its either 2 of them for 400 or one 7970 for 410. I am worried about this stuttering everyone talks about I have never done crossfire before so not sure about that.

Well it sounds like you know what you want to do, if you dont like it you can always return them. Till you try crossfire you are always going to wonder about it. I was the same way. As I have said I like my setup, it works great and I have no regrets.

Decided To do some overclocking on these 7870's of mine. First I wanted to work on just one card so I took the bottom one out and set the other at 1200/1400 on stock volts.
Have been running a stress test for the last 15 min. and the temps leveled out at 58-59. Not to bad for a start thumb.gif

Lets see if I can hit 1300/1450.

Hey Navit, I also use MSI R7870 TF OC but weird sometimes voltage goes up to 1.60volt??? No matter at default clock or overclocked it always like that but only a second. Like this :

That was at stock clock and stock voltage which is 1.218volt, is it normal?? Or is it mis read voltage?? GPUZ and AB read same weird.
Here is another Overclocking with default vgpu :

Ok what driver or Cat do you use Navit? 12.3?? I saw your AB with driver version abit different with mine when I open Afterburner, you have 7.14.10.0901 but mine has 7.14.10.0894 . I think you AMD driver 8.95.5 right? not Cat 12.3.
And default voltage of you card, is it 1.168volt?? You have OC Edition right?? Sorry too manya question, Navit biggrin.gif but please I need your information smile.gif
