but that's the BRP7 app you're running, not the Gravitational Wave application that Ben is talking about. your link shows a host that's only doing BRP7 and Gamma ray. no GW tasks at all on that host.

the BRP7 app doesn't use nearly as much memory as GW does.

U R Quite right.  The 4GB 1050ti box also no MDGWs.  I took a look for some old 2x MDGW WUs from the RX 580 but I didn't find any still listed.  That box now has a 3060ti in it (8GB) but also runs 2x MDGW:  8GB nvidia card running 2x MDGW

 

PS:  I did find this WU from when this box had RX 6600s (gfx1032) in it running 2x MDGW: RX 6600 w/ 2x MDGW

Has anyone been using the AMD

Has anyone been using the AMD XFX SPEEDSTER MERC 310 AMD Radeon™ RX 7900 XTX Black Edition GPU?

The reason that I'm asking about an AMD card instead of an NVIDIA card is because of these specifics:

  • Memory Size: 24 GB
  • Memory Bus: 384bit
  • Memory Bandwidth: Up to 960 GB/s
  • Effective Memory Bandwidth: Up to 3500 GB/s

Although, it does have a GDDR6 (non-x) memory.

It also 'claims' to be 2-slots wide, and yet one site says 2.5-slots and another review says it is 2.9-slots wide.  I don't know for sure, but I think this variation in slot sizes is dependent on using the add-on support holder.

Here's a picture:

What I would like to know is:

  • Have you had any driver support issues?
  • Is it doing BOINC well, and specifically Einstein@Home?
  • How many tasks are you running at the same time?

I'm currently running NVIDIA EVGA 3080-Ti's, and I'd be curious to know how it compares.

3080Tis are undoubtedly

3080Tis on the Linux Special app are undoubtedly faster

here's a host with a 7900XTX : https://einsteinathome.org/host/12861929

recent tasks doing 2x in ~250s (about 125s ea. effective)
there are some ~290s tasks, i suspect it's either the 7900XT, or it's another XTX but running hotter/slower or something. 

here's another 7900XTX host: https://einsteinathome.org/host/13090972
about 410-430s doing them at 4x (~105s ea. effective)

my 3080tis are doing them around 162s at 2x, ~81s each effective. nearly 30% faster than the 7900XTX.

Okay Ian, you win!   LOL I

Okay Ian, you win!   LOL

I know that we've had this 'chat' several times before about AMD vs NVIDIA, and that the NVIDIA 3080-Ti's are superior when it comes to doing any BOINC work, especially with the Linux Special app.  Plus we've had many conversations about the drivers from AMD.  The biggest reason I was looking at AMD was because of the prices and whether or not they can fit within a multi-slot motherboard by having a 2-slot card.

Do you think that at sometime in the near future AMD will adopt DDR6X ?

 

BTW, the latest news/rumors with EVGA closing it's Taiwan plant/headquarters and everybody resigning.  It may be the end is in sight for EVGA.

With that said, your preferences on GOOD GPUs would be..... ???

I don't think AMD will adopt

I don't think AMD will adopt GDDR6X. the 5X was only found on Nvidia and so far 6X has also been nvidia. probably more likely that AMD will go to GDDR7 instead.

as far as good cards without EVGA? i dunno. probably ASUS, or Nvidia FE.

So on Linux/Ubuntu 20 how do

So on Linux/Ubuntu 20 how do you fix installer errors when it complains about missing dependencies?

It a 2400g GPU. But first I need to get the Amd driver installer to run.

The only time I have seen AMD

The only time I have seen AMD installer errors/missing dependencies was in connection with AMD's eula.  The docs read like there should be a pop-up which you can accept, but I've never seen it.  So your install command-line needs to be something like:

sudo amdgpu-install -y --usecase=opencl --opencl=legacy,rocr --accept-eula

Legacy requires the --accept-eula, but can be used for both.

BINGO!  The install script ran without a single hitch.

Now I am back to the actual problem.  This driver doesn't seem to support the 2400G GPU.  The OS is hanging during boot.

As I remember the "fix" was to revert to Ubuntu 18 and install the AMD driver for that version....  :(

My first attempt would not finish starting up the OS. 

My second attempt I re-installed the OS and ran a full OS update.

The Amd gpu driver install script ran fine, again.

The Boinc system could not find any usable gpus :)

So I am stumped.  Might try Ubuntu 22 before I try Ubuntu 18
