Question Melted Pin

[thok794]

Hello
So I own a MSI Z390 ACE for less than 2 months and had a lot of stutter in games so I decided after trying everything inside windows 10, I decided to make a hardware check and I found out that the back side of my motherboard where the CPU goes is like this. It looks completely melted I do not know if the motherboard was like this when purchased or it happened later. What are these "pins" (I hope I call them right as pins) used for ? How do they affect performance and I guess motherboard should be replaced?
These are the images of the backside of the mobo.

Either or it doesn't matter which. I have never seen even a cheap end board look like that. Not sure what they would ever use glue (I would assume hot glue) for on that since the majority of boards are either wave soldered or done by precise machines. I would have returned the board as well is I saw that.

I also assume the new motherboard does not show the same issues otherwise the OP would have stated so or not used it.



A more modern way to check GPU performance is Frame pacing. It measures how ling it takes between each frame. There is also tearing which happens when the next frame arrives in the middle of the old frame.

VSYNC was designed to make the GPU match the refresh rate of the monitor, so if you have a 60Hz monitor it would try to stay at 60FPS. This works great if you have a game that your GPU can keep a constant 60FPS or higher. For example if you played Half Life 2 maxed out on your system you would probably peg the game engines max of 300FPS almost always making VSYNC a viable option. Would be smooth as butter.

However since most modern games are more demanding even on top of the line hardware there is now Adaptive SYNC, known as G-SYNC and FreeSync. Instead of the GPU being matched to the monitors refresh rate the monitor has a dynamic refresh rate and can match the GPUs performance instead to a certain limit. Some have a small band, like say 1-60Hz, while some others have a wide band , like 1-240Hz. So now if the GPU fluctuates between say 30 and 60FPS the monitors refresh rate will adapt and remove tearing and micro-stutter.

Stuttering can also come from drivers or poorly optimized games but if enabling it fixed yours you should be good to go.

In my new motherboard i haven't noticed any problems yet.The online games i tested was Apex legends,Pubg and csgo.From all of these 3 i have experienced stuttering and ghosting in pubg and apex legends,and in csgo just ghosting.

UPDATE: They called me about the motherboard i send back to the store and they told me it was just paper on some tiny holes from the manufactor
