Gigabyte B450M DSH3 and Ryzen 3600

Hi all, had a frustrating day and just wanted to see if anyone out there has had a similar experience with this hardware.

Today my new Ryzen 3600 arrived. I am upgrading from a 3400g for the extra cores + I have a dedicated GPU now so the 3400g was a bit out of place with it's igraphics.

As per title I'm using a Gigabyte b450 board and it's running F50 firmware so should be ready for Ryzen 5 CPUs.

I installed it super easy, booted up and all looked good apart from my displays (connected to a GTX 1660 Super) - they flickered once or twice but seemed to stabilise. I went to run a user benchmark to check the new CPU was performing and then my PC black screened. It was as if the displays just shut off randomly.

Only thing to do was power cycle.. and alas the PC never recovered. Never saw anything other than a black screen until I put in my old CPU again. Tried reseating the RAM, resetting the CMOS etc. On power on all the fans spun up as usual but no signal was ever sent to the display.

Totally stumped. Anyone out there running a gigabyte b450 with a 3600? Is it a pipe dream? I'm no technician but the only explanation in my head is a faulty cpu? Or are these gigabyte boards just temperamental? Don't really wanna return the CPU if there is some way I can sort it.
 
Yeah, works perfectly with the old CPU. I just drop it back in and boot up as normal, then drop in the new one and see nothing but black screens. My main monitor is connected to the GPU via display port. But I have a secondary one over hdmi too.

And yeah I can't see any bent pins. Really weird stuff. Seems so unlikely the CPU is a dud but who knows

What model is your Gigabyte motherboard ?
 
Yeah... Ryzen 5 Support has been in since F40 though, and it's playing fine with my 3400 so I'm reluctant to update unless I really have to.

I think I'll just return the 3600 as potentially faulty and get a new one.

I'll try BIOS update if a new CPU doesn't sort it. The most annoying part is it worked for a few minutes - Surely it'd never POST at all if BIOS wasn't compatible.

Thanks for your help though buddy, appreciate it.

Going a bit crazy here.. thought a like for like CPU upgrade would be painless

I checked bios support also so donbt think its that maybe your unlucky and got a faulty cpu, it happens.
 
the 3200G has iGPU. what is your dGPU?

I would check that the board is booting off the dGPU with 3200G in the bios setting. also try all the ports at the back of the dGPU HDMI and DP ports.

GTX 1660 Super. Bios is definitely set to boot of the GPU (PCIEx Slot 1). Nothing outta hdmi or displayport. I don't have anything with DVI to test but seems unlikely it'd be any different. Just gonna return the 3600 and cut my losses at this point.

Would it be worth trying a fresh one or is this almost definitely my system rejecting the 3600?
 
Have you tried a clear cmos at all?

I have a gigabyte ab350m gaming 3 with a 3600 installed without any issues.

This is on the latest bios as well (F50).

As others have mentioned it might be worth checking the pins on the bottom of the CPU ot maybe just loosen off the CPU cooler a bit. When you installed this did you go from corner to opposite corner or round in a circle?
 
Interesting. Thanks. Tried clearing CMOS with the jumper. Not tried taking the battery out though...

And yeah pins all look pristine. I've took it out and put it back in maybe ten times now, alternating between that and the old CPU. Without fail the old (3400) boots fine, the 3600 fails, so it seems unlikely it's my method of installing the cooler... But I've been doing corner to corner for what it's worth.

Cheers

Check your memory settings, especially the memory voltage. What might have happened is the voltage defaulted to 1.2v while the 3400 was installed, but the speed might have increased, but not the voltage when the 3600 was installed. if its 3000mhz-3200mhz ram installed then up the voltage to 1.35v. Also update the bios version F60 (I think thats the latest).
Give that a go and post back.
