The 8086k (a binned 8700k) was the first single core turbo to hit 5.0GHz out of the box, since then each gen the top 14nm parts have improved the speed and number of cores that can do >=5GHz. If Alder Lake can really hit >=5GHz that's impressive because up until now I don't think a non-14nm part has come close. intel may finally be back in shape with the golden cove design, I wonder how much fab capacity is ready for the newer process.

Had the same experience. Upgraded my Ryzen 4600H laptop to Windows 11 today and tanked my PRP-CF s/iter from 0.60 to 1.15 (without any decrease in power consumption ). Installed a "2021-10 Cumulative Update for Windows 11" (Microsoft KB5006746) from Windows Update and I'm posting 0.60 s/iter again.


I wonder why, if you're upgrading from 10 to 11, Microsoft doesn't push the newest version to start with...

I have a prime95 session on this laptop, and mprime on 2 Colab notebooks, set to use that now, as a parallel test. It will take days or weeks to know whether it's working.

I've had this preference set on v30.6b4 for some time now. At first it would not recognize the work type and I would have to manually add them to worktodo.txt. However I've just noticed the last time it fetched assignments that it now recognizes the assigment type and writes them to worktodo.txt on its own.

See https://mersenneforum.org/showpost.p...6&postcount=57
And it looks like mine worked recently too.

The default setting is 0.25Mbps. This uploads a 100MB proof file in about an hour. If the upload
is interrupted, it will automatically resume from where it left off at a later time.

I'm not sure where this setting is adjusted? I don't notice any relevant settings in local.txt or even undoc.txt, although the latter does mention DownloadRateLimit. Are uploads really limited to 0.25Mbps?

You should be able to adjust it in the Prime95, I think it's named Resource limits. It should be the same place where the disk space settings are.

Well that's embarassing.
I looked at that dialog multiple times and somehow failed to see what was there.
The appropriate settings are also available in mprime.
And it gets written to prime.txt under

[PrimeNet]
UploadRateLimit=<value>

where <value> is the upload limit in Mbps.

Nevermind. Fix coming in build 6.

Has Build 6 been uploaded yet? My latest PRP test should end tomorrow and I want to change versions before starting my next one.

Okay then I’ll use build 5
