I've ran into this same problem with the latest SRBMiner-MULTI using the 20.4 drivers which is newer than 19.x with FiroPow. It seems to think my max buffer size is still 4GB and I'm not sure what to make of the 3004.80 driver version:

[2023-02-18 07:55:33] Starting init of worker threads
[2023-02-18 07:55:33] GPU DeviceID 0 [BUS:03] driver version: 3004.80
[2023-02-18 07:55:33] GPU DeviceID 0 [BUS:03] reported total memory: 8192 MB
[2023-02-18 07:55:33] GPU DeviceID 0 [BUS:03] reported free memory: 8074 MB
[2023-02-18 07:55:33] GPU DeviceID 0 [BUS:03] max buffer size: 4040 MB

TRM works fine running FiroPow.

If newer drivers are now required, which ones are good? The latest ones really hate bifurcation and everything freezes up for a minute when trying to enumerate them.

Also, I have this problem when trying to use --password with firopow. It says more passwords than pools given, even if I only just set a password and not try to pass in any parameters.

Thanks for all your help and writing this miner for all these years!
