Sorry, I don't really know. If you power-up the motherboard, you can connect to it by the ipmi RJ45 port and check the bios version; try to ask it to the seller... maybe you will be lucky.
PS: Buy an item with a good return policy and give it a try. It is not impossible to flash the bios.
Thank you for your comments and that link about the SPI header pinout from the ROG forum, everything really is correct (I checked with a multimeter).
I only had a CH341A programmer and I didn't have a 16 pin clip, and the only solution was to use was to use jumper wires. Guess what? In my city I could only find 2.54mm wires, so I had to jerry rig it. On the motherboard (Asus KRPA-U16) the SPI header pins are in fact 2mm apart, so I couldn't squish more than 2 wires beside each other (the plastic end is just too wide). Took me a while to hook it up, but I had to hook up a naked wire on either side (they were surrounded by the plastic insulation of the neighbouring wires. Checked them with a multimeter just in case
here, the beige cable is exposed and wrapped around the pin
Here I had to expose the blue one.
Anyway, the SPI header pinouts from
were absolutely correct, but I checked everything with a multimeter just in case.
Here's how I arranged the jumper wires for my CH341A:
SPI pin --> CH341A pin
5 --> 1
6 --> 6
8 --> 5
4 --> 4
7 --> 2
2 --> 3
9 --> 7
3 --> 8
I think that if you're also gonna use a CH341A, a usb extension cable will be essential because I couldn't hook up the programmer without having the exposed wires fall off, so be prepared ahead of time and make sure you have one.
As stated in the source, pin 1 is not used.
I'm a complete noob so I'm pretty proud of doing something like this for the first time ever, so YAY.
I used AsProgrammer on Windows, and I had to gamble because the exact chip on this board isn't on the supported list, but I chose another similar one which only has 2 or 3 letters that are different at the end, but the size was also 32768 kB so I just YOLO'd it.
Took 7 minutes to read the chip, and it took a whopping 20 minutes to flash version 0302.
I tried checking the version of the BIOS that I originally had, but it was hard to read (I think I found it, it was like 4102 or something, but I could have read it wrong). If it's important, I've got the dump saved on another drive and I'll upload it if anyone needs it.
No onto my next problem - I've got a 2s1404e2vjug5, and with the overclocking tool it overheats even on 1.8GHz with a IceGiant Prosiphon Elite. I first tried Deepcool Fryzen, but as soon as you load the cores (I did it on Cinebench R15), the CPU die temp shoots >110C on HWinfo64.
Then I got the IceGiant Prosiphon Elite, but the problem still persist. WhenI start the benchmark, the temperature shoots up to 110/120C, and as soon as it finishes, it drops back down to 59 C
Am I screwed? Or is this an inaccurate temp or something?
Or is it that the 2S is that much worse than the ZS?
