[QUOTE=NickOfTime;388583]Flipped the AC on my inverter, 51-53A @ 12V = 625w, including routers and screen in power saving mode...

PSU Corsair HX850 90% (ASUS KGPE-D16 2x Opteron 6234 / NH-U12DO, 2x HDD) ...
hmm, so about 290watts left... and TDP on the CPUs is 115w each so probably 60w to spare...

Edit: Hmm, my inverter efficiently is also peak 89%.. not sure if I need to apply correction to the first 625w...
Edit: Tdp on CPU's, hmm, I also usually use turion power control to bump it to always use all cpu boost mode, so I probably use more than the 115...[/QUOTE]

Keep in mind the efficiency at the various loads of your [url=http://www.corsair.com/en-us/hx-series-hx850-power-supply-850-watt-80-plus-gold-certified-modular-psu]HX850[/url]. It looks like max 91%, so I would use that figure for calculating spare room. My power supply has over heated a couple of times when the air filter in the case below it got semi-clogged with dust, causing crashes, so I'd keep an eye on that, too.

So we still need another 1.8 THz-d/d, if we're giving out 1400 DC assignments per day for the next 26 days.[/QUOTE]


My GPUs have finished their queued LLTF and have started on DCTF at a total of 1.3 THz-d/d

Thanks for all the efforts guys! :smile:

So everyone knows, I'm moving house over this weekend, so I may be out of contact for a day or so. But will keep an eye on things from time-to-time by way of my Nexus.

One with extreme power and A/C capabilities? :big grin:

MISFIT is not UPLOADING my results
 
1 Attachment(s)
I assume it is an ID-10-T error.

In the MISFIT 2.9.2 config parms:
Lookin:C:\GIMPS\GPU\MFAKTC-0.20 <== this is where my results.txt file is

Here is a sample line or two:
no factor for M3776xxxx from 2^70 to 2^71 [mfaktc 0.20 barrett76_mul32_gs]
M3777xxxx has a factor: xxxxxx [TF:70:71:mfaktc 0.20 barrett76_mul32_gs]
found 1 factor for M3777xxxx from 2^70 to 2^71 [mfaktc 0.20 barrett76_mul32_gs]

I know the links to primenet are working because I was able to fetch more work.

I added the extra schedule line to see it happen as I watch...I even stopped/started MISFIT after I added the schedule.
When the time came and went (and I did UPDATE STATS for good measure) nothing happened; no indication it is trying; no errors; no extra results in PrimeNet; no extra working/save/error files in the MISFIT folder ????

[QUOTE=Prime95;388506]petrw1, can you send James a CudaLucas benchmark? I'd like to know the TF breakeven points for this card.[/QUOTE]

CUDALucas up and running. 3.8 ms / ITER for 35.88M DC FFT 2048K

Results once an assignment is complete

HMMM looking at current benchmarks this is NOT very good.
I see 780 for example at about 2 ms for this size DC

An assignment is not necessary: See [url]http://www.mersenne.ca/cudalucas.php[/url] for benchmarking details.

Thanks found it....but man does it take a long time to run.....hours.

You don't have to let it finish, make a million iterations in bunches of 20k or 100k, (use the keyboard to adjust, or modify the ini) and send a copy of the screen and or logfiles, james is wise enough to extract the right data from it.

Let's just say I have provisioned an ICT wiring closet (star configuration, of course), all power and telephony runs are underground, as is the server room... (I'm not kidding). :smile:

Going to be offline for about 72 hours....
