Breadboading Taichi X470, need help.

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I couldn't get my new build to do anything,  other than one fan (out of 6) to spin up at full rpms; no post, no Dr Debug led. 

So went back to basics breadboarding, here's the quick lowdown so far..

Case = Raijintek Thetis
Fans = Noctua U12A + 4 case fans
PSU  = Seasonic SGX 650
M/B  = ASRock Taichi X470
RAM  = Corsair Vengeance lpx (3200)
CPU  = Ryzen 5 3600
GPU  = RX 570 Sapphire OC

So bare bones Taichi with: one stick of RAM in A1 slot, CPU cooler (U12A) plugged into CPU FAN1 - System Panel headers hooked up to power button / led, etc - alarm beeper plugged in. 

ATX power connector and 8 pin 12V power connector firmly plugged into mobo brings about:  

U12A fans fire up properly for 15 seconds - power down - then power back up for another 15 seconds, rinse / repeat. (I replaced the BIOS battery with new which actually kick-started the U12A fans to work).

NO Dr Debug led, no beeps, no beep code sounds, nada.  Before I waste any more time guessing, if Dr Debug led is dead, is the motherboard faulty? RMA time?

Thanks.

	OK, that is not typical behavior so lets delve deeper. Remove all connections from the board, including front panel header. Connect only the 24 pin power and CPU/CPU cooler and then short the power on pins with a screw driver or other conductive metal object. Also make sure the clear CMOS button on the IO panel of the board isn't stuck or depressed by the IO shield. Let us know if you get any display on the debug LED display.

	Hi Xaltar If I short it it starts the fan up and corrects the 'stutter' it just stays on, which I presume is normal. In fact it starts the fan up every time of doing that procedure, what it doesn't do is shut the fan down if I try to short it again - and still no Dr Debug led, not even a flicker.

	Do you know which bios version is on the board? Version 3.40 at least must be used for the Ryzen 5 3600.

	I don't, I bought it because it says "AMD Ryzen 3000 Desktop Ready" on the box so assumed it was either 3.10 or 3.20 BIOS and had read that was enough.

	Just because it says it's Ryzen 3000 ready doesn't mean it is. It means it could be if the BIOS is up to date. My board came with a small sticker on the BIOS chip indicating what version of BIOS it came with. The sticker on mine said P3.20 which meant I had to update my bios before it would recognize my Ryzen 3700x chip. Bios for the Taichi x470 need to be at least 3.40 for Ryzen 3000 CPUs.

	So I deduce from that you had a Ryzen 2xxx processor hamdy and updated the BIOS?

	It appears there is a 'loan boot kit' available from AMD, basically they loan you a AMD Athlon 200GE so you can do a BIOS update. https://www.amd.com/en/support/kb/faq/pa-100#faq-Short-Term-Processor-Loan-Boot-Kit I think I'll still RMA the board as I still don't trust the fact that there is no working Dr Debug. It still think it should have registered something at least to let you know the chip was incompatible at the current BIOS. No LED, no beep cod, no nothing?

	I had a 2000 series chip available and immediately updated the bios. So I don't know if Dr. Debug would've shown any codes if I had my 3700x in there instead. If you don't want to hassle with the AMD loaner program or get a compatible CPU some other way, only way other way to guarantee your board will work with your chip is to get an X570 board. What I did is bought a cheap Athlon chip from Amazon and am going to resell it on Ebay. I did it that way because of Amazon's 2 day shipping.

	I've just spoken to the tech guy at the retailer I bought it from (he does their system builds for the public) and he assures me that any new processors without the correct string information would NOT be recognised by Dr Debug and would remain blank. He also thinks the BIOS I currently have is at 1.50, so I think I'll need to flash twice to get to current 3.60. Seeing as though this particular X470 motherboard was the one I wanted, with exactly what I needed, I'll buy the Athlon 200GE chip and probably keep it. Thanks all for the input, it was valuable to get to this point.
