Title: AVP 2.0 - Video Cards
Post by: BigWick on March 15, 2022, 08:26:18 AM

Received a CPU in from a customer where the fault was "video card". Okay sure, probably means he overheated it.
Video card is a Radeon HD3650 (512mb). Change the batteries, clean the box and threw in the upright cabinet. CPU hangs on POST code 01110100.
Bring it back to the bench, forget to swap the video card and try to save a few minutes by plugging an ATX supply directly into the CPU. I see it POST and give the AVP splash screen on a monitor. Okay so I guess the video card is good? Put it back in the cabinet. 01110100. (???)
Swap my test CPU box into the cabinet and it boots and ram clears fine, so the cabinet, backplane, harness and PSU are still good.

Change boot chips. no difference.
Change NVRAM sticks. no difference.
Change telltale module. No difference.
Leave the hard drive and CD drive unplugged. No difference.
Swap the main board......no difference.   :banghead:
Swap the 3650 out for a new one. It POSTS in the cabinet.  :duh:

Did a ram clear and left it overnight because the telltale battery needed to recharge. Came in this morning, power cycled the machine and....01110100.  :hissyfit:

Again, it's refusing to work with 3650's if the CPU is in the cabinet and plugged into the backplane, but will work if sitting on the bench being powered-only.
What boggles my mind however is that if I throw a Radeon 9800 Pro in that works, but I don't have any cards with a low profile heatsink. The 3650 should work.

How do you decode the POST indicator on these CPU's so I know what its hanging on and why is it being so unhappy with a video card that should be compatible?

Did you figure this out?

I'm curious to know if the 2.0 video cards would work in a 3.0M Brainbox. I'm having trouble locating the e4690 Cards.

And I don't know enough about that kind of tech to tell on my own.

I was able to find in my pile of junk another 9800 Pro that playtested fine with a replacement fan and I called it good.
By that point I was a day and a half into troubleshooting and I just wanted it done and back out to the customer rather than spend days trying to find out why a supposedly good config was doing that.

Cursed, I tell ya. Cursed!

I wonder if it could be that the power supply cannot support the HD3650. The power requirement for that card is quite a bit more than the 9800.
