SkylakeX teasers (aka prime95 29.5)

So, pairing a Skylake X with an AsRock X299 Extreme LGA 2066, it would need an external video board, or this MB has its video board integrated, although not driven by the processor GPU??

I don't see any video ports on that mobo. So no, it doesn't have onboard video on the mobo. You will need external graphics if you don't want to run headless.

p.s. My Designare X299 has DP ports, but they're actually inputs for the thunderbolt ports. And they need to be powered with an external GPU. (yeah, weird)

Thank you Mystical. Any hints on a "cheap" but "beefy" X299- and LGA2066-ready MB with the same characteristics of the AsRock but with a graphic output?

I will search the web for it, but your (people reading) experiences might be helpful, thanks.

There have been high failure rates with the GTX 2080 Ti's. It's probably defective.

I'm not sure they even exist. Do you really need every last PCIe slot on the motherboard? You can easily pop in a low-end card into one of the PCIe 2 slots to leave all the 3.0 slots available.

Indeed, that's what I plan to do. Such MB DID exist in a not too far past.

Hi. I have a problem with prime95 29.5b3 linux build to return a certain result.


prime.log contains:


Got assignment _: PRP M40493
Sending expected completion date for M40493: Oct 31 2018
Sending result to server: UID: _, M40493/known_factors is not prime. Type-5 RES64: 28B346EDA839BB__. Wh8: _,13840,00000000, AID: _

ar Insert t_gimps_results_log failed: _ GUID: _, exponent: 40493, C2D_CPU_GHz_days: 2.8907502777778E-5


(some values replaced by _ or ... for this post). Similar messages about the same exponent repeat after this, apparently every 70 minutes. I can't see the result listed when I query the exponent and the exponent stays assigned to me. This is the corresponding result for the test, in the local results.txt:


{"status":"C", "exponent":40493, "known-factors":"92433209129,1667510486489,171398538300197951,269366686360389758713349

":"3C4F...}

overall the line is a few characters >1029 in length.


Later I'll try to clear the spool file and rerun the exponent, falling back to prime 29.4 if the same problem happens. If that doesn't work I'll unreserve the exponent so somebody else can try.

I am disappointed that the Benchmark for this is no better than my son's i7-6700 running at 3.4 with much slower RAM(2400 I recall)

Anyone else with similar hardware have any comments?

When I look at Benchmarks for 7820s I don't see a big difference.

Mine is running 3990Mhz.

I am also using 29.5 build 3 on Linux. I am running on a single core (c5.large on AWS).

I put the line

PRP=1,2,40493,-1,99,0,3,5,"92433209129,1667510486489,171398538300197951,269366686360389758713349089,72084381262372670043690044179567991113"

in my worktodo and ran it.

It completed successfully.

Can you try submitting the results.txt line manually via https://www.mersenne.org/manual_result/ ?

Excellent, thank you for running the exponent. My worker was running on an r5.2xlarge AWS (one of 4 single core workers). I tried submitting the results line from results.txt

{"status":"C", "exponent":40493, ...}

to the manual result page. It gave this error:

Found 1 lines to process.

This is just a guess, but perhaps since you added the task without an assignment id it may not have written that or some other fields into your results line, making it shorter. I thought that perhaps that is the reason it does not accept the result I found.

Yes, my results line was lacking the usual "aid" field at the end. It's hard to imagine that makes a difference though.

Maybe you could ask Madpoo to look at it.
