2nd reboot PC runs better ??!!

[gottistar]

Here are some pc specs
7950x
64gig ddr5 geil 58
M2 980 Samsung
4080
Msi mobo gamer plus

I just recently put together this pc , it fought me abit at the start as far it wouldn’t post (black screen) , I narrowed it down to the memory, I changed it over to another brand different speed (5800), anyway all working good now, but…

First boot pc runs laggy, it’s takes a long time to settle , struggle to move the mouse cursor for example, after the second reboot it runs perfectly, any ideas why this is occurring?

Obviously being a new build you should make sure no wires are pinched or shorting. With this large of issues I'd fully disassemble the build and fully remove PSU for visual inspection and testing of it and cables. Especially since you didn't list what psu you have. Opening the door to being underpowered or, far worse, using cables that aren't certified to work with it.

Next step would be error testing on OS drive with it alone mounted. Followed by any others in sequence to see if they suddenly cause the issue.

Mobo being faulty is what you need to prove here. Remove everything else and RMA if problems persist. Someone else may have better ideas but this is fairly logical process of elimination having already changed RAM.

Update your motherboard bios

Update your motherboard bios

It’s the latest bios for the Msi mobo, there is one newer but it’s a beta bios and that made it worse ..cheers for the suggestion

The PSU is the silverstone 850

If I understand correctly... every time the PC does a cold boot has issues and when restarted its ok?
How much time have you waited on the first cold boot? Is there a chance that after a few(?) minutes turns out ok without reboot?

I would get HWiNFO64 (run sensors mode only) and set it to start with windows. Set it at full screen when you open the window so that is it shows as many sensors as possible.


Please copy/paste these (main) settings (right click tray icon > settings)



1st cold boot: try to use it for like 10-20min (if not more) while HWiNFO64 runs in background
2nd boot (reboot): try to use it the same way again for same amount of time with HWiNFO64 in background

Take sensors window a screenshot for each run with at least 10-15min (if not more) and post both here

Try to copy paste what is visible on each section below
I see you also have an ultrawide screen so there will be no problem

Run time can be seen on bottom right

Is this a 2 DIMM kit or are you populating all 4 slots?

I was popping 2 dims when the problem started now im using 4 dims and still the same problem ..

I wonder if it's something associated with DDR5 Memory Training. A quick search reveals other people have this same "problem". I suggest a little research on the subject of Memory Training.

If your RAM is overclocked, e.g. at XMP 5800MT/s, as an experiment, try running it at JEDEC default e.g. 4800MT/s.

To get a better idea of how long each boot operation takes, temporarily install BootRacer or similar, to measure the times more consistently.

My 7950X rig built in December 2022 is running stock 4800MT/s on 2 x 32GB DIMMs. There is only one XMP setting in the RAM and it, too, is 4800MT/s with exactly the same timings. When I bought the RAM, 32GB DIMMs with fast XMP settings cost more than I was prepared to pay. As a consequence, I've never run my RAM at higher speeds (choosing stability over speed on 24hour+ rendering runs).

I don't notice any significant difference between cold boots and warm restarts on the 7950X, but they're not exactly fast. Windows 10 start up times from M.2 NVMe 1TB SSDs on the 7950X are around 60 seconds, but the PC has to check the boot ROMs in the 10GBe NIC and LSI SAS HBA PCIe cards. The presence of three M.2 and five hard disks adds slightly to boot up times, as Windows checks the "dirty bit" on each drive. Many things can affect start up times.

Do you have Windows "Fast Startup" enabled or disabled. Fast Startup will probably improve boot times if enabled. I switch this feature off and disable hiberfil.sys too. Main reason is Fast Startup can mess up booting Windows from alternative SSDs in the same machine. CHKDSK would start when I switched back to the main boot drive if Fast Startup was enabled, which was annoying on machines with multiple drives. It could take CHKDSK to confirm all the hard disks were OK.

How much time have you waited on the first cold boot?

Ummm a "cold" boot is when the PSU has been UNPLUGGED from the wall (or PSU master power switch is set to off).

It is important to remember if the PSU is plugged in to the wall (and, if present, the master switch set to on), the ATX Form Factor standard requires the supply provides +5Vsb standby voltage to several points on the motherboard, including the RAM, USB and Ethernet ports, and the case's front panel power button.

When you shutdown through the Start menu or with the case's front panel power button, that simply puts the computer in a standby state. It is never fully off (cold) until all the voltages are removed and that only happens when unplugged from the wall, or the master switch is set to off.

I would take everything out of the case and assemble it on a clean, unfinished bread/cutting board and see if the problem remains. If it does, swap power supplies before replacing anything else. This is because everything else depends on good, clean, stable power.

If it works outside the case, verify you only inserted a case standoff where there is a corresponding motherboard mounting hole. Then carefully reassemble in the case ensuring all data and power cables are securely connected.

Ok, no argument. I should have been more clear. I meant to say literally cold boot, in ambient temp and with nothing warm up after a restart for example.

 

[Bill_Bright]

No big deal. It is a common mistake - in fact, the second time this morning someone meant the computer had been turned off for hours and, in terms of temperature, had cooled off.

If it technically did not make a difference, it would not matter. But since in this case, where voltages, data, and [possibly corrupt] settings remain when the computer is simply shutdown (put in standby mode), ensuring everyone is on the same page does matter.

Thanks for your understanding.

Interesting read , seems like using a different brand with different timing made it better , geil at 5800 is good , gskill at 6600 no good, also I took some Kingston 5800 out of my sons pc and it worked perfectly as well..

Ok, no argument. I should have been more clear. I meant to say literally cold boot, in ambient temp and with nothing warm up after a restart for example.

I should have stated , i use the pc most of day on my day off it all works as it should, go to bed , wake up go to turn it on , it works like $hit , I wait for it to settle, follow the promps for 2nd reboot , then it works perfectly… that’s the process, it’s not a HUGE pita , but it is a why is this happening on my lovely new build ??!!
