I'm about to give up and send the 6600 back.  I would assume I'd have the same issues with any Navi based card.

 

PS:  mountkidd - why r u running w/ anonymous platform?

How much memory do you have in that pc? I run a 6600 just fine in one of my windows pc's, maybe you can setup a VM and run it that way.

OK, time for another shot at the RX 6000 under Linux Mint:

1st I shut it down, used systemctl to disable boinc-client so it wouldn't start up.

I swapped the RX 6600 in where the RX 580 was and powered the box back up (iGPU still on and my monitor is on it).

1st a ran amdgpu-uninstall.

2nd $ sudo amdgpu-install -y --usecase=opencl --opencl=rocr --accept-eula

Other than to start BOINC back I'm not sure what else I can do at this point.

Radeon-Profile shows NO load on the processor and no utilization of the vram with the main clock bouncing from 0MHz to 800Mhz and back.

Also noticed this on some pending/in que BRP WUs (all the GW and MW WUs bombed out within seconds):

Fri 21 Apr 2023 05:20:47 PM CDT | Einstein@Home | Task M22_1_dns_cfbf00017_segment_8_dms_100_20000_32_2950000_2 postponed for 900 seconds: Not enough free CPU/GPU memory available! Delaying next attempt for at least 15 minutes...

Only thing I can think to try is to go back to BIOS, re-enable the iGPU so I can set a larger UDMA and then disable the iGPU again.

SAVE for reboot.

No change.  Did notice the 6600 is only using 19w (from Radeon-Profile) which has to be idle wattage.

Can anyone bail me out?

Skip

boinc-client.service part is done.  Should be able to swap cards and do driver uninstall / reinstall (currently have opencl=legacy) in a couple hours.

Thanx.

EDIT:  Looks like it's gonna be late tonight or tomorrow b4 I can swap the cards.  OK, It'll be Monday.

From only a couple completed tasks and just rough numbers:

GammaRay - 32.5% decrease in times with RX 6600 over the slightly oc'd RX580

BuRP - 45% decrease in times 6600 over 580

 

Other projects:

 

Prime Grid works ...

GFN18 - 6600 has reduced times by 53%.

GFN17 - 6600 reduces run times by 27%.

GFN16 - I don't see any gain on these and possibly a very slight degradation.

GFN15 - the 580 was anywhere from 77-105 seconds, the two 6600 completions where both a hair under 50s..

AP27 - 6600 reduces run times by 58%.

 

MW Separation tasks fail for reasons Ian&Steve C. have already found:

clCreateCommandQueue

 

Error creating command queue (-6): CL_OUT_OF_HOST_MEMORY

 

OK, 'nuff of this.

A few side notes.  My used Sapphire RX 580 (Pulse variant) had a TDP/PPT cap of 155w (the Nitro's have 160w cap).  I had the core clock pushed to 1420MHz (think it comes at 1366) and the memory @ 1785MHz (vs 1750).  If loaded enough it would sometimes run up close to that 155w PPT cap and start backing the clock down to around 1400MHz.  The Nitro+ versions will hold closer to 1420MHz due to the 160w PPT.

The RX 6600 (an ASUS card, also bought used) has 100w TDP/PPT cap and I thought a 2750MHz clock but it seems to think it's 1615~1620MHz and a mem clock of 875MHz.  Radeon-Profile doesn't seem to be able to move those but it will set a multi-point fan curve and I have as yet to see it get over 59C and right now it's at 55C running 2x  BuRPs.  A significant bit cooler than the RX 580 ran and is only reporting 81~89w against it's 100w cap.  It does however seem to be much warier of that 100w cap as above 81w it seems to draw the clock down from 2620 to 2615MHz.  It might really run 2750MHz at a mid range load (time will tell).  None of which bothers me at this point.

Now for the important stuff:

I owe MOUNTKIDD a HUGE debt of gratitude for all his help with this box and it's AMD cards over the last few weeks.  I don't know how I'll ever repay him.  Many thanx my friend.
