Title: software for 7970 and 7950 Post by: ddd1 on May 06, 2012, 10:02:27 PM I'm currently mining with guiminer/opencl.
7970 is 1125mhz on core and gives about 640mhash. My 7950 at 1030mhz core gives about 495mhash. Q: would diablominer or other software give more then that? They are only 96% core load for some odd reason, I'm using catalyst 12.3 I know that 12.2 is recommended might try that later.

I'm using CCC 12.3 as well. 12.4 really messed up mining for me.

Thanks, cgminer is alot better compared to guiminer. cgminer, 12.2 pre beta driver (reccomended by cgminer author) -I 9 -k poclbm --auto-fan --gpu-engine 1100-1180 --auto-gpu --gpu-vddc 0.88 --gpu-memdiff -150 gets me 702Mhash/card on 7970 poclbm currently gets me best performance How do I know which kernel is running? I guess that means that youre 7970 gpu core is between 1100-1180mhz and the memory is 150mhz less so 950-1030mhz? I'm now 1125/1050 on the 7970 and it gives 660mhash, the 7950 is 1100/1250 and 575mhash. I would like to overclock more the core but it is capped at 1125 for 7970 and 1100 for 7950 how do I unlock that in cgminer or windows 7 because I have watercooling?

Card dropped from 83 degrees to 74 degrees, and now my clock from 1125 to 1180. A higher clock and much lower temperatures. Getting Currently: "697.8 mhash" Its insane how much this card can undervolt and overclock at the same time Stock: 1000>1180 Voltage: 1.17>0.88 Volts(25% under volt) All the previous cards I had never OC and Undervolted this much.

Ckolivas himself admits that cgminer cannot set the voltage on 7970s: https://bitcointalk.org/index.php?topic=77238.msg860395#msg860395 (https://bitcointalk.org/index.php?topic=77238.msg860395#msg860395) Of course at 1180 you're not undervolting: you're at stock voltage. Which is pretty fine indeed :) -- Bye |
