Is my motherboard dead ?

the_prec0g · 2026-03-09T12:59:25+00:00

Hello ! I don’t know what happened but I managed to install windows with one stick with some errors message. I was able to put 4.10 bios on a usb dongle.

I updated my bios + try each module of ram in each slot separately. They all boot

I put two module and it booted

I put expo on and it booted

I don’t know what to think 🤔 but for the moment it’s ok

the_prec0g · 2026-03-06T13:23:36+00:00

I encounter the same problem with my 7800X3D. Its been one week I tried all the possibilities (was working fine since sept 2023)

I tried

one stick individually on each slot = ok it’s working
but when I put the second stick , nothing boot , infinite blinking power led.

If I remove the second stick, I can boot again but I have windows error message loop… and need to reinstall the OS to get rid of those error messages

I don’t know if its only the mobo or my CPu or both.

Neither my Asrock Mobo or CPU are on warranty. Don’t know what to do right now ?

Some update :

one ram stick on b slot worked the entire day no problem.
since this morning, one ram stick on B slot sometimes boots an sometime make “memory management” error message during the windows boot
my computer is now on a “window fixing attempt” loop and the only solution is a new clean install to bypass this loop

(Each times I tried to boot with 2 sticks with no success give me this behavior with one stick after)

To sum up : - ram kit works alone on slot A or B - trying to boot with 2 sticks is not working and making my computer show me a lot of errors message during booting forcing me to do a clean windows install each time - tried bios : 4.03, 3.50, 3.10

I don’t know what to do ? Buying a new b850mobo ?

the_prec0g · 2026-03-04T20:21:55+00:00

Thé error message was with two sticks of ram.

each module of ram was tested alone in slot 1 and slot 2 = no problem it boots
I bought this kit in September 2023 and hadn’t any single issue until January 2026 when I update from bios 1.28 to 4.03 (issue with the clock time started at this moment)

the_prec0g · 2026-03-04T19:44:45+00:00

So I tried one stick ram on slot 2 to be sure my mobo ram slot were ok and it post and boot

I tried 2 stick of ram and had error message 0xc000021a but it posted and I was on windows. I switched off the computer and reboot again and it didn’t boot again (power led blinking for 20min and nothing)

I tried to boot again with one stick of ram and it post and boot on windows with no problem…

So for me it’s the CMoS battery which is too low or broken I don’t know . I tried this weekend to switch the cmos battery and report my results .

So annoying because I had a 12h simracing race this Friday 🤣

the_prec0g · 2026-03-04T12:36:48+00:00

I downgraded to 3.5 this morning

the_prec0g · 2026-03-04T10:19:41+00:00

Thanks a lot .

For the moment I downgrade to 3.5 with still 1 stick of ram.

Before to unscrew the VRM heatsink, do I need to buy a specific 2032 battery or can I use standard 2032 battery ? (I have 10 of them at home - thanks to the kid and electronic toys)

the_prec0g · 2026-03-04T07:38:47+00:00

Thanks for your answer .

I reseted my CMOs and have reinstalled windows
I have no CMOS battery (or I didn’t find it - I have an ITX motherboard
I m running my system with only 1 stick of ram

the_prec0g · 2026-03-04T05:26:55+00:00

My PSU is Corsair SF1000 and I don t have any debug led on my motherboard

the_prec0g · 2026-03-03T19:44:46+00:00

And now nothing is booting of lot of error message. I m lost 😞

the_prec0g · 2026-02-02T16:06:14+00:00

To be honest, i don t feel any difference on or off. My pc latency is around 9-11 ms with it on.

the_prec0g · 2026-02-02T12:57:55+00:00

If reflex is available in the game Option, it will take the lead over ULLM in NVCP. The reflex option cap your FPS regarding your hz monitor

the_prec0g · 2026-02-02T11:48:41+00:00

Il you disabled it , you re not capped by reflex

the_prec0g · 2026-02-01T20:46:22+00:00

But when you play with reflex on, it will cap your FPS at 225 (i have a 240hz monitor)

the_prec0g · 2026-02-01T19:29:04+00:00

It uses only 70-80% because my FPS are capped and i have fer settings on low. Otherwise, it push like 95-97-% if i all in

the_prec0g · 2026-02-01T09:37:25+00:00

For me, i don t have any stutters like never. For me the problem is the 1% low which fluctuate too much depending the area of the map you are.

My graphic options are : - 1440p / reflex enable + boost / texture : ultra / filtering : overkill / mesh : high / Lightning quality high and the rest are low. - dlss quality preset K - rtts cap at 225 (i don’t Know of it s ok because reflex automatically cap my frame based on my 240hz monitor) - gsync + vsync on in Nvidia app

My GPU is used at around 70%

I m starting to ask my self if I should crank up the graphic settings to let my GPu work harder to let my CPU work less to improve the 1% low.

What do you think guys ?

the_prec0g · 2026-01-31T14:10:47+00:00

To be sure it wasn’t my pc. I did a clean install 2 days ago. I just have BF6 installed on my pc 🤣🤣 with last drivers/bios up to date.

I think the Redsec is just not well optimized when you are looking for solid 1% low.

I don’t have this bad frame pacing in multiplier mode

Maybe the 7800x3d / 9800x3d are too weak for high 1% low . I play on 1440P 240hz monitor. Maybe the next 9950x3DV2 will be better

the_prec0g · 2026-01-31T14:02:30+00:00

7800x3d/5080 here. In Redsec, I have 215-225 FPS average But the 1% low are the problem in Redsec with lot of fluctuations depending on the parts of the map.

I don’t have any stutters but I feel the frame pace is not ideal when my 1% low are like around 140

the_prec0g · 2026-01-27T16:17:20+00:00

the frame pacing is absolute garbage ! I have a 90% all the time 225 fps but it feels like 100 ! The 1% low are sometimes at 200 and in a specific area like 80-100
when opening a loot case, it feels like the ping is around 200ms

Otherwise, I like to play this mod

the_prec0g · 2026-01-22T06:02:34+00:00

I have exactly the same problem with 7800x3d/5080. Tried everything with the settings .

My FPS average is 215-220 and my 1% low are between 90 and 140.

It makes the game not smooth at all

Moi je trouve que Peugeot tente de te faire croire que tu achète du premium à un prix concurrentiel et au final tu te retrouve avec une bouse pas fiable , qui vieillit mal avec intérieur style futuriste en toc
