Bump!

I guess as I get older it gets harder to justify a several hundred dollar electricity bill per month.

Plus, there is no chance I can hang in the top 10 anymore so that takes a lot of the fun out of it.

A little progress is being made:

It looks like bayanne and garo are churning out some TF GPU work, so I added a GPU to the team.

Seriously, one GPU can make a huge difference. And if you set it up with a controller, it won't affect your games and stuff.

Is there room for a video card in an iMac? They generate a lot of heat!

Here is a list of cards and their relative performance:

A GTX660Ti is where (I believe) the price/performance/wattage sweet spot is.

PageFault[/url]":2bmxnund]Really? I want to keep using an antique 8400GS, but the serber boart I have chosen could run multiple cards. Trouble is that these cards can't run themselves ... I would lose a core or two. I have to settle on a six core xeon for now, so cores are scarce.

Actually, you can TF on the GPU without feeding it from a CPU.

- GPU sieve supported on GPUs (CC >= 2.0), thank you very much, George!
GPU sieving is enabled by default, for old GPU (CC 1.x) you must disable it manually in mfaktc.ini (variable SieveOnGPU)

(Note that this is the program for Nvidia cards.)

Time to bump the thread!

FWIW, here is what three reasonably-priced (GTX980) cards can do in about nine days:

Here is a chart of ALL of the people who have turned in a result in the last year. (I assume some of them are still using the old generic 'TeamPrimeRib' login.)

Even a single computer or video card helps the team!

endless mike[/url]":1dg2mdri]I've been messing around with mfaktc on my Windows 7 dual GTX 460 box. It's quite a pain manually downloading work and uploading results. My worktodo has run dry a few times when I miscalculated how much I'd need. Is there anything to automate this? I've read about MISFIT, how do you set it up?

I manually feed my GPUs once a week. The workload is pretty consistent so I just reserve a little extra.

Are you using the GPU72 interface to get work?

Support forum, lots of help: http://www.mersenneforum.org/forumdisplay.php?f=103

If you post for help there they will hook you up.

endless mike[/url]":11ask08y]That's quite true. Look where I was when you last posted this in January compared to now.

Is anyone here?

 

[Xyzzy]

It is nice to hear from you guys!

I'm still working a bit with my GPU, here and there.

I just passed a cool milestone:

 

[Xyzzy]

No, I don't have very much compute power available.

I've slowly replaced most of my hardware with low-power versions. I only have one computer that uses more than 15 watts now and that is just for the occasional game.

 

[Xyzzy]

A new prime has been found. They haven’t announced who found it yet, though.

There is a new breakthrough that eliminates double checks.

Read more here: https://www.mersenne.org/

 

[Xyzzy]

Note that with the new error-checking PRP test you can:

- Run Prime95 on overclocked or less-than-reliable computer hardware (CPU) and it will correct for hardware/memory errors.
- You can run gpuowl on a GPU and it will error-check and correct hardware/memory errors.

My cheap 2060 Super is faster in first-run PRP tests (110M) than my i9-9900K or my 3950X.

A Radeon VII is the fastest platform of all platforms for prime searching.

If anyone needs help setting this stuff up let me know. It is surprisingly easy!

A new Mersenne prime?
