Yeah. I've unlocked the clocks in there and everything. Just need some more time to work out what's stable etc. I'm just about there on card one although it is taking a long time. Then I need to work out card two's limits.

I have.

Off topic but I am impressed with how the performance is on 7950 number one with even a smallish overclock:

You should be able to ramp up that memory clock a fair bit at stock volts, try 1600 mhz first

watching!
Very impressive only 1 fps difference in minimum fps! And when you compare the price difference that's truly something!
Given up for the night. Will re-commence tomorrow. Though may just bench at 1150/1600 to get an idea. Though if I've got a pap clocker I do need to know ASAP to decide if to return.
The first one seems OK. Not golden but very good.
What are the ASIC quality on those cards by the way?
Soldato
Nice one.
Stop making vids and start benching
Just getting his priorities right psy.
With a little bit of voltage on the memory, it goes a long way on the memory clocks rusty.
84 and 88 from memory. 84 is the one I'm on at the mo.

My 7970 is asic 68.4 but still clocks to 1275

IIRC you can turn this feature on and off with the Enable ulps with regedit
I find with it enabled i cant monitor the second card with afterburner unless i reload it when in game
Anyone know how to unlock Afterburner for the second card when you have two? The unlocked limits are applying only to card 1.
Going to swap them over to check them individually but would be helpful to know regardless.

That 1080p performance is impressive. I'm guessing if you can reach 1200/1600 you will match or even surpass 'the beast'. 1700mhz should be doable on the memory though. Remember you can add a little voltage to the memory in afterburner, its a drop down menu son the main page.
Remember you are not voltage gimped anymore

make sure you get the AMD Catalyst Application Profiles update for the driver or some games won't see any performance increase.
1200 is easy. I'm only on 1.137V at 1150. This seemed high enough to rule out any random crashing while I tested but I'll bring it down when it's settled.
I benched 3DM11 @ 1250/1700 but performance was quite low suggesting some kind of issue my end as they were the same clocks roughly as a 11600 graphics score.
Looking for a benching clock of a touch over 1200 and whatever I can get on the memory. This should fulfil the brief of matching the performance of your average 7970 overclock and *should* match or be a little under the beast at 1080p. If I'm matching the beast at 1080 with a set of clocks then that's perfect because we'll be able to tell how much difference the 384 bit bus makes at triple screen res when otherwise performance is the same of at least very close.
My job is pretty flexible - you can go in when you want and leave when you want. The work is there no matter what time you get there. So I got to work at 6:30 this morning and will leave around 4:00 as there's a lot on.
Is is sad that I got in early so I could crack on with my actions and leave ASAP to continue?

If your score was low it often means you need a touch more voltage. Sometimes it skips a few frames if there isnt enough voltage and you get a lower score.
Its not sad at all to go in early, you are lucky your work is flexible
