The upcoming Radeon VII should be beastly at GFN21 and GFN22. Nearly 7tflops of FP64 for $699. Might be able to beat a Titan V since it has over 50% more memory bandwidth.

If you don't have an RTX 20x0 card (the new ones), 399 is still the last suitable driver.

Thanks. That dropped my estimated runtime on a 1080 from 11 hours to 6 hours.

Is the newest nvidia driver suitable for this challenge or is another driver recommended like with the previous challenge?

At this late stage I'd suggest running "as is" if that is known stable. The risk from overclocking is you may get bad results, or crashes when you are away from the system. That could cost you more in lost time for the challenge than you gain. If you had looked at this earlier before the challenge, you would have time to check it is ok before doing it. Edit: just noticed the original post was some days earlier... didn't see until now.

BTW my 1080Ti (Asus Strix OC version) seems to be averaging 176 seconds a unit.

That's impressive. My watercooled 1080 is only getting about 267 seconds per task (although it's only at 85% power target)


Mine is at 233 seconds not oc'd and no strix.


1080? What clocks is it running at?


Mine is a 1080Ti and is running 1898 gpu and 5005 memory.

Try running 2 tasks at once next time. My 1080 was doing a task every 211 seconds on average once I switched to 2 tasks at once

My MSI 1080 with standard factory OC is returning two units every 485 seconds or about 243 seconds per unit.

Whoops I forgot that I should be running multiple tasks per gpu. I haven't run PPS Sieve in a long time

Hi

I:ve a Question ;

My Graca is GTX 1080 TI ( Windows 10 )

for PPS ( Sieve ) Running Time is 2 Min 55 - 3 Min 02 sec

21 tasks per hr. 502 per-Day

can I overclock the Graca again ? Perthaps thats better vor 2 Min tasks

My SETTINGS ARE RIGHT ?

Greatings

T.Armstrong



You won't get from 3 min to 2 min by overclocking. You can probably improve it though. PPS Sieve seems much more forgiving to overclocking than GFN.

By the way, the results currently showing up on the leaderboard won't last. They're not valid. Something got borked and those two tasks completed in a couple of minutes and didn't upload a result file. Once the the wingmen come in and the validator runs, they'll be removed from the leaderboard.

Ah I was wondering how someone was on the leaderboard already. Figured someone must be running a liquid helium cooled 7900k...

Also I saw that AVX512 should be on mainstream and server CPUs later this year. How much will that improve LLR runtime?

My power went out 2.5 hours after the challenge started lol
