Can anyone explain to me what this means and what if anything
needs to be done ?

All I can say is I have no idea sorry lol

Hi TouchuvGray

One thing with the newer AMD cards is their Double Precision capability is reduced with each generation, as they are aimed at Gamers, which puts us crunchers at a dis asdvantage, since Milkyway uses DP.

I did notice that in the above printout , it gave a warning about NVIDIA drivers present but no NVIDIA Gpu found.
Maybe it might be wise to do a full cleanout of the drivers and then reload the AMD drivers.
There is a program c aall DDU via guru3d.com that does this really well.

Also these cards do reasonably well over at Einstein@home, maybe use that as a backup project.

Also does this computer have 3 AMD gpus in it.

I suppose you could  check on Milkyway forums to see if your cards can do 2 workunits at a time.

Cheers

i have removed the drivers and re installed the AMD drivers on
Machine #1, the one with the two RX580's in it

Will do so on # 2, the machine with the RX5500XT in it later today.

i had been hoping for a lot more than i am getting from the 5500XT
based on core clock, memory clock, and GDDR6, vs GDDR5.

i think i will wait a few days to see if there is any improvement and then
swap one of the RX580's over to machine #2 and put the 5500XT in machine #1
just to see what happens.

Hey your RX580s are smashing it, but your 5500xt is running times similar to an RX570.

Had a quick look at some computers running similar hardware over at Milkyway at home.

The RX580 has 362.0 - 385.9 double precision.
The 5500XT has 302.2 - 324.7 double precision.

On that basis I would think the RX580 would be better for M@H.

This list seems to confirm that.

https://milkyway.cs.rpi.edu/milkyway/gpu_list.php

Silly me, and here i was thinking that a newer next generation
card would be better.

i have the RX580's running 2 WU's each now.  So far it looks
like about 35% improvement.

:boom:

Possibly a dumb question. Would an older  card like a HD7970

FP64 (double) performance
    947.2 GFLOPS (1:4)

be even better with the higher double precision capability
despite the slower GPU clock and memory clock ?

Greetings

I think it would be better in crunching times, but it is known to be very power hungry do you own the card?, as I wouldn't buy one these days.

Maybe check on MW forums, there is couple of threads dealing with GPU's.

Its been a long time since I ran MW.

Regards

i don't own one but i can get one for $100.00 AUD on Gumtree.

Hi TouchuvGrey

Sounds okay, but I would be bargaining for 50 dollars at the most, otherwise I would be putting towards another RX 580 onwards.

You might only get 6 months out of that 7970 but you might get 2 years out of another RX580

The other thing is to look at is, energy efficiency on your GPU crunching.

My thoughts only, but others here who run AMD cards and do Milkyway, might be able to offer other solutions.

Cheers

PS, I only run NVIDIA Cards (at the moment), when the weather cools down, I run GPUGRID and Primegrid and the 1660 Super I have, does well for the low watts it uses. (Einstein sometimes as well)

The results from WUProp@home are good for comparing graphics cards:
http://wuprop.boinc-af.org/results/delai.py


Here are some average (min-max) run times in minutes for Milkyway on Windows 64 (I don't run Milkyway so hopefully these results seem realistic).

HD 7970: 2.5 (0.1-7.3)
RX 580: 2.0 (0.8-7.5)
RX 5500 XT: 3.2 (1.4-5.4)

if i go with another RX580 it looks like it will have to be a used one.
They seem to be discontinued.   : (

Anybody out there have an RX 580 they want to sell ?   or an R9 280   
the numbers on that look good.

Sorry I dont have an RX580, but I have seen some depending on where in Australia, range from $140-$200 on the 2nd hand market.

Seems though that due to the short supply of new AMD RX 6000 series cards, this has blown out the 2nd hand market prices.

A little bit of detail also to help you out - Also depends on how much you want or have to spend as well.

HD 7970 (2011 Card) Over 200 Watts
R9 280X (2013 Card) Over 240 Watts
R9 290X (2013 Card) Over 280 Watts - Very Hot to RUn
RX 580 (2017 Card)   Over 190 Watts
Radeon VII (2019 Card) Over 300 Watts - Very Expensive but its the KING

See If you could pickup a 2nd hand RX 580 for $150, thats better than spending money on a 2nd Hand 2011 or 2013 card, imho.

This is what I could pull off some websites and also Milkyway at home.

Cheers

I personally think the best value cards for M@H is the R9 280X. At about $100 for a second hand one, it does really well at M@H and Einstein@home.
The RX480 or 580 is also a good option and better on the wallet for power usage. I see you could buy 3 x 280X for the price of 1 secondhand RX580. Again... you may want to factor in power usage though.... and heat.
When i run my 280x or even my Vega 56's, you are pumping out 80 - 90 degrees C per card.

This is where it really depends on the projects you like running. Ie - I like M@H and E@H and my cards do well at those projects..... Primegrid though.... all my cards (including the Radeon VII) get smashed by NVIDIA.

New ( 2nd hand ) box up and running.
i5 4570, 16GB RAM, R9 280X water cooled GPU
running 1 WU at a time right now. Will run that way for a
day or so and then try 2 or maybe 3.

Water cooled...wow  :thumbsup:
I run 2 consecutive on my 280x.

Congrats TouchuvGrey, no stopping you now  :cheers:

 A bit more in the mix now

   Milyway@Home    GPU WU's

Machine #1  R9 280X + RX580
Machine #2  R9 280X
Machine #3  R9 280X
Machine #4  TX 580 (2)

    Universe@Home

     All machines running CPU WU's

   

It might be early days but are you reserving a core for each of those GPU's? ie - Your 8600K is crunching 4 CPU tasks out of your 6 cores? (because you have 2 GPU's so hence reserving 2 cores)

Thank you Chooka. As usual i have overlooked something.

Like the other day when i spent 2 hours trying to figure
out why a computer would not boot into Windows and
finally realized that i had left one connector unplugged.

All good mate  :thumbsup:
I was looking at your credits and they were quite low. The GPU was being starved. Watch it rocket now over the next couple of days!  :cheer1:
