As this is a brand new forum, I thought I'd open up a thread to encourage new members to introduce themselves a bit.. now hey.. let's not get too personal.. ok ?
And if you wouldn't mind to keep this thread \"clean\" let's try to keep the the chitchat (i.e. even the welcome to the board replies) to a minimum or this thread may get to 100 pages fast
So I'll start things off :
My name is petabyte and I'm a forum junkie. :oops:
I've been off the wagon for a number of years and countless times I've tried to stop but it's useless.....

Hello everyone!
The Asrock A380 low profile card (ID 8086 56A5 - 1849 6006) have an power limit of 45W. Intel removed the possibility to increase power using the software utility, anyway the card is in an proxmox machine that doesn't run windows.
The same hardware is in another form by the name Asrock A380 Challenger that have the same VRMs and the power limit is at 60W. I searched online and found on another website an .bin bios file from the Challenger variant, that I flashed using an CH341a. Flashng worked well, I put the card in PC and booted. GPUz shows that new device ID is 8086... -
Hello everyone!
I've paired an Intel Arc A380 with this PC but the performance is not so good because the bios don't have 4G decode and Resizable BAR enabled.
With an CH341a I extracted the .bin file from the 25Q128 SPI memory. Can someone work some magic on that .bin file to enable or add the 4G decode and REBAR to it?
The model number is: 2ZX70AV
Thank you!...
