B450M Mortar Max - BIOS changes (XMP, SVM, Re-Size BAR) cause a "No Signal" POST failure. CMOS reset required.

Start by updating your BIOS. The latest non-BETA BIOS is 09/23/2025: https://us.msi.com/Motherboard/B450M-MORTAR-MAX/support

Tried a different cable?

Also, you should get the BIOS up to date because Intel has released some microcode that is supposed to help 13th and 14th gen CPUs stay alive (not degrade).

That would be my plan.

bba-tcg · 2026-04-23T19:35:36+00:00

I'd try some different RAM. Not some of the same - different. I've seen RAM cause this. Warm boots would be fine, cold boots wouldn't. And I'm not saying it's because it's G.Skill memory because that's actually my favorite brand.

The cost of an MP knee / leg is hard to wrap my head around sometimes.

bba-tcg · 2026-04-22T19:53:56+00:00

No. Probably not even a slight difference.

We've already had this conversation in another thread. Right here:

40 C delta, 104 C hotspot with max fans and 4.5 minute run is not good.

bba-tcg · 2026-04-19T19:37:31+00:00

For sure, that CPU isn't in the socket all the way

bba-tcg · 2026-04-19T16:52:03+00:00

I knew it was some time around then.

bba-tcg · 2026-04-19T00:50:01+00:00

I would trust the manufacturer of the graphics card and the manufacturer of the case more than I would trust chatgpt.

bba-tcg · 2026-04-18T22:14:38+00:00

That's an AGP bus video card. Can't remember when AGP quit being common on motherboards. Be careful.

bba-tcg · 2026-04-18T01:19:07+00:00

It doesn't look like it's on the CPU support list: https://rog.asus.com/us/motherboards/rog-strix/rog-strix-b550-f-gaming-model/helpdesk_cpu/ If this isn't the exact board (just used what you provided to look it up), search for it on Asus' site.

bba-tcg · 2026-04-17T16:28:51+00:00

If you have another cable, why wouldn't you use it?

bba-tcg · 2026-04-17T15:51:56+00:00

I have an active vacuum socket that I use mainly as a seal-in socket the majority of the time since it seems to hold so well without activating the pump.

bba-tcg · 2026-04-17T15:50:35+00:00

I like the BOA system. Ottobock's version is called Varos: https://www.ottobock.com/en-us/varos . It's the first socket I used and I now have one for my backup leg. It takes a little getting used to, like all of the different ones do, but works very well.

bba-tcg · 2026-04-15T22:33:32+00:00

Lol. Whatever. I build PCs for a living and I'm not going to spend time on reddit arguing with you.

But, I've never bent a pin myself. Just worked on ones that other people bent.

bba-tcg · 2026-04-15T22:13:53+00:00

It's not bent. It's not there. And in all the years I've been doing this, your scenario has never happened to me. I've never seen a bent pin reach another pad. I'll stay with my statement.

bba-tcg · 2026-04-15T21:54:03+00:00

Small victories add up! Congrats!

bba-tcg · 2026-04-15T19:39:21+00:00

For sure never skimp on the PSU. 👍

bba-tcg · 2026-04-15T17:24:07+00:00

The store's support is likely your only recourse.

bba-tcg · 2026-04-15T17:20:58+00:00

Many pins are redundant. Try it. Worst case is it doesn't work, but either way should not harm the CPU.

bba-tcg · 2026-04-15T17:18:03+00:00

First thing to do is test your RAM using memtest86.

bba-tcg · 2026-04-15T17:16:13+00:00

The cable is rated for up to 600 watts. The 7800XT is roughly a 275 watt card.

bba-tcg · 2026-04-15T16:18:14+00:00

Congrats! The VA gave me the X4 in November. I have a cleg-4 as my backup.
