Z620 Bios update for better support of RX 570 8GB

[V15MYassin]

Hello there. 
I recently bought a Z620 with Xeon E5 2687 W V2 32 GB of RAM, and RX 570 8 GB GPU.
The Bios version release date was 2012, and the GPU doesn't perform well as expect as I was using GTX 970. So, do you think that updating the bios would enhance the completability of the GPU?
The issue I'm facing with the GPU is too much frame drop and game lagging, Also, I'm using the latest driver version. I heard that there where driver issues previously with RX. Will I need to use an older version of the GPU driver?

Thanks in advance.

The HP Z620 QuickSpecs document v1 was dated 3/6/12, so there is a good chance you may be running on an original 1.x BIOS that came with that early Z620 workstation. It is not until you get up into the 3.x level of Zx20 BIOS releases that things much improved. You can do better...

The very early BIOS versions required an initial "step-up" procedure before you could proceed to a final "leap-up" to the latest 3.96 version. No need to go sequentially up through the interval releases. There are numerous significant security and bug fix improvements awaiting you. Related, in January of 2014 an official HP communication/advisory was released about this and is attached below for your review. The Z420 and Z620 motherboards use the same BIOS and step-up procedure and for those you need to get to at least BIOS 1.23 before you can leap straight to the latest 3.96 BIOS. Things are just a bit different for the Z820. The HP ReadMe and SoftPaq for the first phase can be downloaded from HP (note the newer https security link addressing difference versus what was in the old advisory). These links still work if entered properly: 

The HP ReadMe:

https://ftp.hp.com/pub/softpaq/sp64501-65000/sp64701.html

The HP SoftPaq installer can be downloaded via:

https://ftp.hp.com/pub/softpaq/sp64501-65000/sp64701.exe

The old and less old BIOS versions had helper apps included, written for XP, then Windows 7, then some for early W10. There was a spate of bad BIOS flashing that resulted from running an old updater app under a new OS, plus some bricks. I now only update BIOS from within BIOS. The one Zx20 brick I made was from not using this method while trying to cut a corner in a rush... never again. For the xw and Zx20 series of workstations you run the SoftPaq, cancel out of it right after it runs, go into the root level of your C drive to find the SWSetup folder, and in there you'll find a folder named SP64701. Poke in there and find the J63_0120.BIN file (a copy is in the "DOS Flash" folder).

Copy that .bin file over onto a FAT32 formatted smaller thumb drive onto its top level. Shut down, insert the thumb drive when your workstation is fully shut down, cold boot into BIOS, and navigate to the Flash System ROM BIOS entry to initiate the flash. Let BIOS restart if it wants (and some BIOS upgrades will restart themselves a couple of times). Shut down, cold boot again, and then repeat the same thing for your leap with the J61_0396.bin file you harvested the same way from the 3.96 SoftPaq (SP100222).

Starting with the Zx40 family of workstations BIOS got significantly more complicated but there still is a way to update BIOS from within BIOS for those and the versions above. We only use that bit more complex method in those too.

Thank you very much for your response.
