NVidia GPU hashrate testing (NeoScrypt)
-
Okay, i have a Gigabyte GTX 660Ti OC 2GB card, i have found the main boost to performance is memory clocks.
Afterburner settings
Core 1333MHz (+144 on the core in afterburner), default core was 1032, boost 1111, which actually boosted to 1189 or so.
Memory 3549MHz (+546 on the memory in afterburner), something like 1775MHz actual, 7.1Ghz effective.
Power Limit +13% (makes no difference that i can see, as the card only hits ~90% power, but gives a higher roof for bursts of whatever)
Fan @ 40%
Temp 68c, drops to 57c with fans at 95% (highest they will go)
cgMiner config
worksize 16 (seems to get a little higher speed than 32)
intensity 14 (higher for me kills the display drivers and cgminer crashes)
pool giving vardiff usually between 5 and 10, WU/min hits around 4.4,
Output
mines at 34Kh/s
WU/min of 4.4 ish, (vardiff varies wildly between 5 and 10)
(Perhaps i can create some sort of page where we can submit our settings and tweaks + hashrate?)

Tomorrow will have a watercooled gtx 770 in my system (so long all goes well), so this post is reserved for that.
Also my i7 3770K mines @ 24.26Kh/s, running @4ghz on stock fan, 7 threads (last thread for cgminer), 71c
will also update with new cpu temps etc once i get my watercooling loop and blocks fitted

http://hw.neoscrypt.tk/index.php looking good? should there be more/less information shown?
i will add a submit page which will allow people to submit their own cards etc

I would like to use couple of old nvidia cards - 8800GT and GT220, what software I can use? cgminer-3.7.7b crashes with buffer error…
-
Ow, I cgminer-3.7.8 working and even on Windows XP! I get 4.7 Kh/s with 8800GT with starting settings (-I12)
-
GTX 750Ti ~ 39-40 Khash default settings and -I14
