Computer Issues

Built my new PC. ASRock x870 RS Pro.

My issue is that I bought two sticks of 16GB RAM. One of them seemed fine, but I couldn't get the 2nd to work in any configuration. Basically it just wouldn't POST at all (fans would make a pulsing sound, but had CPU and DRAM error lights on MB; if I change BIOS from Auto to 6000 which is the RAM speed, the pulse goes away but still won't POST). Was going to RMA it, but they basically said they wouldn't send me a replacement until the other was sent back. So bought a 2nd set of RAM. PC has been working fine with the one stick for the last week and a half or so.

Got it today and it's basically the same issue. My one good stick of RAM seems fine, can't get the others to work in any configuration (single or dual). I did get one of them to work once (it seems finicky) but it was a mismatched pair and I think Newegg will likely throw a fit about sending two different SN RAM back. Tried to fiddle around with it some more and can't get anything but that one stick to work.

There's no way 3 out of 4 are crappy, and the MB itself seems fine since it works with that one stick of RAM.

I'm getting pretty frustrated and have no clue what is going on.

Did you try all 4 in single DIMM configurations?

Any MC or Best Buy near you that has anything in stock? Try to buy a "pair" that hasnt been beat the fuck out of by the shipping network. Second - is the motherboard rated for the speed you're wanting? What about the brand, does it work well with your mobo? One pair of sticks I bought had RGB on it and actually needed a hair more voltage than it was rated at, etc. But in that scenario, I could at least get into the BIOS.

Yep. They're G.Skill Flare X DDR5. The one stick works period. The auto I think puts em at 4500, but 6000 seems to make no difference. Like I said, the only thing it changed was the fans didn't do the pulsing thing, it sounded "normal." Except it just sat there not posting for 15 minutes (left it there on the assumption maybe it's training, which I don't understand, but also makes it hard to troubleshoot if it's doing anything or just broken).

Ok so what I'm saying is, have you put all 4 in slot 1 and they each work but only single?

If so it's probably bad board

No, only the one seemed to work in slot 1 (well, B2). Tried them all individually, and switched the good one to A2 and tried the others in B2, and none of that worked.

Anyway, I've got the mismatched pair working. As I said in the first post, it was acting finicky to get it to work; I did also end up redoing all my PSU cables into the motherboard which may also have helped, but I honestly don't want to fuck with trying to swap it out again cause that just led me through a 2 hour nightmare of POST errors.

I'll just send back the other two and hope Newegg doesn't match SN's and hope for the best.

Maybe you do have bad ram. Personally I wouldn't keep it. Ram is just finicky especially at modern speeds. If it doesn't boot and post flawless you're just asking for future trouble IMO, like phantom crashes and other errors.

Update BIOS.

C'mon now, you don't think that's the first thing I did?

Did you verify that it updated? BIOS shows latest BIOS version? BIOS defaults loaded?

Ram in A2 and B2 slots? Ram listed on the QVL for that board?

Alright nerds, I got one that I haven't really started the ol' Googling on. Maybe one of you guys have come across this.

Unfortunately had a dud 13900k cause of the damn microcode stuff so I just replaced my MOBO/CPU/RAM with one of those new fangled 9800X3D's and an ASUS X870E. I use 4 monitors, and the way I'd been using them previously is how I have it setup again. 3 of the monitors are plugged into my 4090. The last monitor, not sure it matters but it is an Acer XB2761HU, is plugged into the CPU's integrated graphics. I have it running at 1440p / 144 hz.

Now, randomly, the monitor will just shut off. Straight up turn off, but Windows 11 still detects it. The only solution I've found so far is the just restart the damn thing and it goes back to normal. I have hibernate disabled in windows and I've checked most all the power settings I could think of in Control Panel (see below). I haven't mucked with anything in Bios so far and the very little I've found has people talking about idle/C-states in Bios. I'm very comfortable screwing around in BIOS, I've overclocked many a CPU in my day, although these days a bit rusty because of chasing small hellions around all the time now.

As mentioned my GPU is an nVidia 4090 with 3 of 4 monitors plugged into (those have no issues) and the monitor that is randomly not getting a signal is plugged into the mobo via USB-C. Now that I think about that very well could be the issue but I never had that problem with my old rig (13900k on Asus Z790 HERO). God damnit. It's probably the USB-C cable isn't it? I think I have an Anker that was approved by Benson Leung. God damnit.

Have any of you run into this before?



Edit: Spelling is hard.

Check your USB and Thunderbolt / chipset drivers to see if they need to be updated? Cable could be a thing as well.

In the same category of issues I put together a mid-level tower and rotated some old ones out for the family. Oddly enough I ran into a driver issue with an ASUS board where it popped up a warning for UCM-USCI device - code 10 device could not start. Had to search for a random driver listings site which gave dozens of possibles but none of them were in any downloads from the ASUS site, so i googled one of the solution filenames: DRV_Thunderbolt_Intel_UWD_TP_W11_64_V14113400_20230818R.zip and that brought up a reddit post of someone who linked to the exact URL from ASUS' site. Weird, but installing it made the warning go away maybe for some USB-C port that i wasn't using.

Drivers are 100p up to date for chipset. Just had to do a fresh install. BIOS updated too. Will look into that, not seeing anything funky like that right meow.

Oh snap, completely blanked and forgot the new fangled MOBOs have HDMI 2.1 so I reckon I can do that. I'll give that a whirl. Def agree w/you though. Is gotta be some USB fuckery going on. Unlikely (but could be) driver related or some power bullshit in the BIOS. Not sure enough to care and check given that I can just do HDMI (at least I'm bout 90% sure that'll be able to push 1440p/144hz).

check usb hub (in drivers), it's always set to sleep/powersave, thats why you have to disable it if you have wireless

Device Manager>Generic USB Hub>Power Management

this is the usbc monitor right?

Yes, USB-C.

I just disabled all that power management shit you mentioned. It's only gone out on me once today so... we'll see? Thanks for the tip.

Well I did that on Sunday. Doesn't seem to be the issue - still getting random monitor shut offs. Gotta be the cable. Didn't see anything in BIOS that jumped out at me for a setting to switch.
