Just wonder what memclock are you running at?
I'm going by memory (no pun intended), but I'm pretty sure I upped the memory clock to its max when I found out it was heavily memory dependent, so that would be 1300 MHz for my 5870. 
Topic: 3x7970 Mining Results. - page 7. (Read 61705 times)
Someone with a 7970, please measure the exact length of the card. My Gigabyte Super-5850 is on a 5870 carrier and just BARELY fits, it rubs against the ass end of the harddrives. I wanna make sure a 7970 will actually fit.
Is there any table or something where we can see the performance for a 5870, 5970 etc. with Vanitygen ?
Maybe we can add these results to that table / page ?
My 5870 gets around 31 Mkeys/s with 935 core clock: https://bitcointalksearch.org/topic/m.610714Maybe we can add these results to that table / page ?
Don't underclock the memory when using vanitygen, it reduces the key rate drastically.
wow good tip. Didn't think of that.
On edit: looks like vanitygen is heavily mem clock limited.
You get 31 MK/s @ 935 core and I get 20 MK/s @ 775 core (5870 and 5970 have same core). Your core is 30% higher but you get >50% higher throughput which makes me think that even @ 1000 MHz memclock is the bottleneck.
Just wonder what memclock are you running at?
Also sorry 7970 to push this off topic but maybe it helps in getting best throughput on a 7970 also.

Kinda. There is the first post of vanitygen thread, however it is somewhat vague though.
Code:
AMD Radeon 58XX, 68XX GPUs: up to 23.5 Mkey/s.
AMD Radeon 69XX GPUs: up to 19.5 Mkey/s.
For the record a 5970 get ~20 MK/s PER GPU @ stock (725/1000) (40 MK/s for entire card).
Get the 'Clocktweak' tool (for windows) from Phelix (link can be found on the forum) and check out which voltages / corespeed / memspeed works best for your cards.
You will be surprised how efficient a 5870 can be! 2.x MH / W can be reached easily.

I'm using Linuxcoin, so AMDOverdriveCtrl is what I'm using. I'd like to know where to start though. Stability testing can be a lengthy affair, so I'd really like to know his stable voltage/clock combinations. You will be surprised how efficient a 5870 can be! 2.x MH / W can be reached easily.

Can OP or anyone else who has a 7970 benchmark vanitygen?
https://bitcointalksearch.org/topic/vanitygen-vanity-bitcoin-address-generatorminer-v022-25804
You want to use oclvanitygen.exe
It should only take a minute or two. Make sure the device you are going to use is not in use (if you are using cgminer you don't need to stop just (G)pu menu (D)isable, then GPU #)
oclvanitygen -d 0 1Bitcoinz (0 = device # and the string is the address searching for 1Bitcoinz is impossibly long which prevent the generator from getting lucky too soon)
Then just let it run for 30 seconds or so to normalize any variance. You should see a line like
PRovide the MKey's and the core/mem clocks.
Thanks

Are your cards installed in a linux box? what's ur linux distribution/driver version?
I just bought a HIS7970 and I can't make it work on my centos/fedora box.
I installed catalyst11.12 driver, aticonfig report "No supported adapters detected"
while "lspci|grep -i vga" shows: 01:00.0 VGA compatible controller: ATI Technologies Inc Device 6798

My dedicated 5870 rigs are getting about 2.3Mhash/watt on 80+ Gold PSUs.
What clock and voltage are you using to reach this performance per watt figure?My mining rig (~95W idle power draw) with only its 5870 running can get around 1.72 MH/W. With both the 5770 and 5870 running it gets around 1.83.
But then again it's overclocked to 930 MHz for the 5870 and 1000 MHz for the 5770. I'm thinking about undervolting to reach a better MH/W figure, but I'm not sure which voltage/clock combinations are stable.
Wow, so Tom's Hardware totally bullshitted their "bitmining" results? Ha.
Not really. They didn't have any software that would even run correctly on the cards. They probably also didn't know enough about it to realize that significantly dropping memory clocks doesn't hurt hashing performance. It doesn't look like they tried undervolting the cards either. Most are more concerned with how they overclock. You mean that atitweak (https://bitcointalksearch.org/topic/new-command-line-tool-for-overclocking-ati-cards-linux-25750) doesn't work with 7970s?
No clue. If they're anything like the 6000 series chips, then no. Well... sort of. With the 6000 series cards, you couldn't drop the memory clocks down lower than 125Mhz below the core clock. If you were running at 1000Mhz, you couldn't go lower than 875 (etc). You also couldn't adjust the voltage. With the 5000's, the code in AMDOverdriveCtrl interacted directly with the hardware to change the voltage.
I ended up flashing the BIOS on all of my 6000 cards to custom clocks/voltages to get around the problem. I'm not sure if a program came out since that will adjust them (in Linux).
I could not wait.....just bought as many as I could on Newegg. I am a sucker for this sh*t.
So you're the reason I couldn't buy one right away on launch day..
I had to wait 3 solid days to find a website that actually had some!
Wow, so Tom's Hardware totally bullshitted their "bitmining" results? Ha.
but since there probably aren't any programs for Linux that will allow me to change the clocks/voltage on these cards yet (besides what's allowed in aticonfig), I'm using Windows to test this.
You mean that atitweak (https://bitcointalksearch.org/topic/new-command-line-tool-for-overclocking-ati-cards-linux-25750) doesn't work with 7970s?
Nice. I'm not sure how you came up with 720Mhash per card though. Just noticed that.
Jesum Chro.....I have no idea how I came up with that. I am embarrassed.
Oh well....600+ per card is pretty awesome none the less.

Just wondering if you can verify these numbers were on a 4x 7970 setup? I might have to go buy if it is....
Yep.
amazing. Cant wait to see what a 7990 can do.
