XFX RX470 MOSFET driver IC identification *help*
Hi all
Trying to identify this mosfet driver ic on my XFX RX470 8gb. I don't have the schematics or boardview to assist. The markings on the IC are AZ1. See picture.
If anyone has the schematic or board view I would much appreciate it if you shared it! 🤞
Failing that, is there anyone who can help identify this component?
Thanks... -

R9 290 Missing PX_EN
Have an R9 290 I'm looking at. Seems I don't have a PX_EN. What should the voltage level typically be for this signal? What is required for the GPU to give this signal? Thanks... -
Re: GTX 1660 BIOS Beep Error
Just to update this thread for anyone who may be interested.
I reflowed the memory ICs and replaced the BIOS chip with a new flash. The card is now working!
Thanks to all for the advice.Leave a comment:

Re: GTX 1660 BIOS Beep Error
Thanks will have a look next time I get a chance. Going to wait for a 1.8v adapter for my programmer and have a look at re-flashing. It uses a Winbond W25Q80EW 1.8V flash memory chip.
Will update the thread with results! Fingers crossed!...Leave a comment:

Re: GTX 1660 BIOS Beep Error
Thanks. No broken caps. no shorts found in diode mode.
3.3v on PEX_RST goes through an AND gate ok. AND gate has a 1.8v Vcc and 1.8v output.
I have had an oscilloscope on the refclk +/- and can see a clock signal.
Not able to see and signals on the pex tx/rx lines though.Leave a comment:

GTX 1660 BIOS Beep Error
Have a GTX 1660 SUPER VENTUS. When trying to boot its giving me a beep code error. I get 1 normal beep followed by 3 fast short beeps.
All voltages on the rails and resistances are correct. The GPU gets warm.
Tried in a different PC with the same results. msi b450 pro motherboard.
Any ideas?
Thanks.Last edited by lewistech; 03-11-2022, 06:04 AM. -
