New challenge with XFX 7950 GPUs

So yes. I am on my 2nd rig. Happened to purchase XFX GPUs by posting from litecoin mining hardware comparison site. It is a reference but not 100% trustworthy. My XFX TDKC is not even near 700s as indicated in that site. Argh.. -_-;;
Well, I purchased for less anyways so I guess it is what it is.

I got 2 TDKC and 1 TDFC. 2 TDKC are currently running around 550KH/s without any changes. Weird thing is when all 3 of them are running at the same time, TDFC runs around 500 and one of TDKC runs less than 500. hum…. and TDFC runs like close 80 degree C. I don’t like that either…

I am in middle of decision. Either get rid of that TDFC and get another TDKC or try to set separate batch file and tweak it. Let’s see how it goes…

At least, I met my goal of getting 1LTC/day (currently at ~1.3 LTC/day) running with 3.5 MH/s total.

Rig #2

Finally all the parts arrived yesterday. Here are the items.

Cgminer setting

i 13
tc 8192
core 1050

Currently getting 525+ on each card.
I will update with better result later.

So…. #2 rig is coming up soon.

I have decided to get 2nd rig.
This time I purchased XFX 7950 FX-795A-TDKC. It seems to me that it might only pull 600 KH/s on each card. hum…
Will see how this leads to.
