So...
here's what issue I've been running into.
First... my rig:
Gigabyte GA-B250-FinTech LGA1151 Intel ATX Cryptocurrency Mining 12PCIe 3.0 DDR4 Motherboard
https://www.amazon.com/gp/product/B07988FLFW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1100GB of virtual memory on a 500GB SSD.
I have 10 RX 5700XT cards.
(3 XFX Reference and 7 Sapphire Pulse cards dual bios cards)
https://www.amazon.com/gp/product/B07TB5FBV6/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1https://www.amazon.com/gp/product/B07WC7683C/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1All ten have the 1500 strap bios mod.
Windows 10 ver 2004
Currently with PM 5.1c and Adrenaline 19.9.1
Now... for some reason my clock speeds are:
Core: 1400
Memory: 880
cvddc: 880
If I upgrade the driver (to say 20.4.2)... a random card will crash. Guaranteed. Never the same one. If I remove one I have a pretty good chance of it being stable BUT not at those clock speeds. I have to change the memory to 1750. Any higher and I get a crash. (blue screen)
Temperatures seem fine.
Command: -mi 14 -hstats 2 -mt 2 -tstart 60 -tstop 85 -wdog 1 -tt 60 -ttli 90 and I'm averaging 546.6 for all ten so that's almost 55MH/s. I can't really tell how much from the wall because I have it on a 220v circuit with two other machines but it looks as though each card is running between 104w to 110w.
So my questions:
Why is my current driver (19.9.1) displaying 880 for memory but as soon as I change driver I have to double the memory to make it work?
Why would my rig crash (BSOD) with the latest driver that everyone seems to say is "stable"?
It seems to run fine as is... but it sucks that I can never seem to update my driver. I've tried DDU and that doesn't help. I've tried MPT. I've done the bios mod... went back to stock bios (for each card that I individually saved but later found out that GPU-Z corrupts some of the saved bios files. I'm *thinking* that the GPU-Z backup was corrupted, modded with RedBiosEditor and since I flashed it to the cards I could have *possibly* messed something up... but then why would it run fine with 19.9.1 driver? Now I'm hearing from RedPanda that some manufacturers aren't even letting customers RMA their cards if they've been bios modded because of the PID mismatch so even if I acquired a fresh bios somewhere online the PID wouldn't match up.
So... I'm thinking that my best option is to find the original bios for
Sapphire 11293-01-20G Radeon PULSE RX 5700 Xt and XFX RX-57XT8MFD6 cards.

Flash them individually, then with just ONE card installed flash the latest Adrenaline driver... then plug in each one separately and hope that it works.
Unless... someone else has any other suggestions.
Personally... it's working fine for me other than the fact that I can't update the drivers so I'm not in any hurry... but I am open to suggestions if anyone has them.
Thanks!
After 20.4.2 the memory change to real memory in PhoenixMiner is not half... the crashes come because you push to high the memory... test all of them at 1750 Mhz ...
