Test Setup and Overclocking

ASUS EAH6970 Review

Test Setup

Slightly different to our 1366 setup with the i7-950 we wanted to see how well the HD6970 performed elsewhere and so have put it in our LGA1156 rig. Not only does this give us a chance to get a wider range of results, but also could be the swansong for our i7-870 with the forthcoming P67 boards.

Intel i7-870 @ 4GHz
4GB G.Skill Trident @ 2000MHz
Gigabyte P55 UD4
Thermalright MUX-120
Cougar CM1000 1KW PSU
Windows 7 64-Bit

ASUS EAH6970 Review


When we tested the HD6970 recently we found their was a block at 950MHz when you hit the top of the slider and so couldn't go any further.

We waited with anticipation for the Voltage Tweak BIOS included with ASUS graphics cards to see if this would improve the situation and allow us to break through the 1GHz barrier. However the rather odd thing is that even with the ASUS SmartDoctor the limit was still set at 950MHz. So the superb BIOS had nothing to do but twiddle its thumbs.

The latest variant of the HD6970 comes to us via ASUS. Does their voltage tweak BIOS enable extra performance?

Something still doesn't seem right. A colleague is still scratching his head here.

But looking at it from my pov, I've seen that issue with using an overclocking tool before. You ramp the slider as high as it'll go and you feel you could take it further - and it just won't allow it. It happened

to me recently using afterburner on a 8400 (which is besides the point), but you feel the 'tool' is being told the up/low limits. Perhaps the bios is the key.

If it were mine (I mean donate to me to play with), I'd delve into the bios fiddling menu like atitool/afterburner has and try and massage the limits. From memory tho, if the tool doesn't know the card's bios, it will limit what you can do. I'd still fiddle with it tho.

This is besides the point tho. Off the shelf, something still aint right to me.

Voltage tweak and a oc limit ? Nah, definitely not.

I hate to harp on about it, but those bios versions from the ref card and this would be interesting. I'm going to see if there's any revisions coming out in the future too.Quote
