ok nice score, but I am wondering why did you run it at very low resolution? at least try your benchmark at 1920x1080 bro...HD7970 is more than capable to run any games/benchmarks at 1080p at max image quality.

Any users here with 7970 dcii? Have you guy changed the thermal paste to arctic cooling mx4?

My HD7850 Oc-ed to 1000Mhz @Stock voltage.



Stock 870Mhz


1000Mhz


Very satisfy actually, I gained 7-10FPS on Sleeping Dogs for free.


Next target should be 1100Mhz. Memory speed untouched, I do not see any increase of performance.

Hi bro,

I suggest you to run Unigine benchmark with everything maxed out. Please set AA to 8x, AF to 16x, resolution 1080p correct already and last Tessellation set to Extreme. You may try benching both stock and OC, lets see how far HD7850 can be OC'ed and we ca compare with 7970.

Will Try again tonight, Let see little baby HD7850 chasing the score of master HD7970.

Share out the average score of stock HD7970's score. Needed for comparison.

Ok heres the Unigine score, All maxed out as in the pictures. Later I'll upload some 3dmark scores...btw I'm on catalyst 13.2 beta3 driver.

Stock single HD7970 (925/1375):


Oc'ed to 1250/1650 @ 1.275v:


so its ~14 FPS improvement for free, lets see how HD7850 do at extreme tessel.

What's your temp like on load after oc? Water or air cooled?

^ Water cooled system..max temp for above session was 47degC for OC. For stock clock I think maybe a little lower around 43degC

Awesome temp!

Here is mine where everything Max out:

Stock


OC-ed to 1050Mhz.



Not yet mess with Voltage to go beyong 1050Mhz and memory speed. Next time...

Btw, I having some screen tearing/line occur when benchmarking Unigine and gaming. It happens on stock and OC as well.

V-Sync is on, FPS is below 60. Just noticed today when I carefully watch Unigine benchmarking.

my current monitor left at uni bro, now sem holiday, using old lcd at home max reso only 1440x 900
can use living room lcd, but later kna scold by my mom

Haha no wonder..ok.

I Will update some benchmarks on Sleeping Dogs, DMC Devil May Cry and Crysis 3 later on

Yeah I saw it too since few years ago..I believe its something related to the application itself and not due to our GC or Driver bugs. Anyhow I'll try to run unigine 3.0 on my other rigs using HD5850 and 8800GT. Will update it here tomorrow..

shepard Are you using reference 7970 now? And which bios that u r using?

Its a sapphire 7970 dual-x OC ver and not reference one. However I believe sapphire is using reference PCB just that they change the Cooler to Dual-X. I flashed the original OC Bios (950MHz core) to normal Dual-X 7970 (925MHz/1375)..this one:
ATOMBIOSBK-AMD VER015.014.000.004.000000

Is this Ghz Bios? If I'm not wrong reference 7970 can use those Ghz Bios right.

This one is a normal BIOS not GHz. Yes reference 7970 can be flashed to GHz BIOS...the 7970 I'm using already have GHz BIOS in it. Just flip the switch and I have a 7970 GHz edition

Does the GHz BIOS give you any overclocking improvement? One of the reason that I don't want to use stock bios is that having hard time to unlock in AB, while early unlocked bios(MSI one) is way more easier to unlock in AB, not to mention I can push more further comparing with stock for some reason.

OCed MSI HD7870 2GB DDR5 at 1200/1440, +20% powertune and 4.4Ghz i7-3770K. Using Catalyst 13.2 Beta3.
