Here we go!! Finally I can post!!
i7 3770
H67
660Ti
16GB ram
Windows 7
Driver 314.22
no OS optimization (even Steam is running in background)
bad-bad-bad ventilation (Cooler Master Elite mini-itx)
with Stratum_Proxy feeding (everything seems smoother, highly recommended):
2013/04/10: 159.45 khash/s - conf 42x7
2013/04/09: 132.50 Khash/s - conf 147x2
Some hints I like to verify with you:
- I managed to get 24 khash extra using the CPU, forget the Hyperthreading and setup 3 threads (if you got 4 cores), I've no hints for dual cores. Sticking to 4 or 8 threads (full cpu load) dropped the GPU at about 100 Khash. Giving 7 threads (so using HT) had basically the same bad impact
- don't mess with the console window (drag, tab, scroll, etc), just scrolling dropped the rate of a chunk from 150 to 110. After the test (keep the mouse steady!) stick to your pool dashboard to see the results (in my case 147 over 30 jobs - test done today)
I'd like to test:
- vanilla desktop (no Aero interface)
- different set of drivers (in this case I should setup a dedicated partition and format everytime - I'm too lazy, I must admit it)
- Linux
...meanwhile I'm relocating to a new home, so I' really don't know when I'll be able to do that :-|
Two last words:
- it's an awesome work, I've mined only 0,2 LTC of which 0,1 was burned by the pool for the transfer to my wallet (damn testing!), otherwise you already had had a donation from me too
- the software is really SOLID. It ran almost 24 hours (from an itx computer!) without any hiccup. Meanwhile Minerd had two crashes!
since you have an i7, why not switch to the internal Intel HD graphics for your primary display and then let the nvidia cards run their thing in the background. This will eliminate any drops you see from moving the mouse, scrolling, moving windows, etc.
...unless of course it's not a dedicated mining machine and you use it for games or other 3d work. As for your loaded cpu dropping your gpu hashrate, I have no ideas as we have the same cpu and I don't experience that.
I've got the following and haven't experienced anything that you've mentioned (including the effects of a fully loaded cpu dropping your hashrate). - maybe it's because I'm using the intel hd graphics as my primary display.
i7-3770k @ 4.6Ghz
Z77 chipset
24GB ddr3 1800
2x GTX560SE
1 GT430
Windows 7 (Aero disabled)
driver 314.22
I get a total of ~240Kh/s from the gpu's. 43Kh/s from the CPU (6 threads).
