Stuttering in Games after failed CPU-Overclock

Hey Guys,

So i bought myself a new Graphics Card (GeForce GTX 1080 GAMING X 8G), together with a watercooling set to overclock my i5 3570K a little more. Before i installed the watercooling system, i had my GTX 1080 in my Rig and everything worked just fine. After i installed my watercooling loop, i tried to overclock my CPU to 4.5 Ghz. I did everything as said in the tutorial i used and after i hit ''save changes & reset'' the message ''BOOTMGR IS MISSING'' popped up even before windows was started.
I tried tons of different ways to fix it and in the end it somehow worked.

So i tought i must've forgot to change an important setting in the BIOS settings and i tried it again and did everything very carefully. But the same thing happened again and this time i couldn't seem to fix it, even tough i did everything i did last time.
I then ended up reinstalling windows 7 and all my programms.

After that i bought a new PSU (750W, before it was only a 8 year old 550W) and also new RAM when i was at it. Now i can overclock my CPU to 4.5 Ghz @ 1.21V.

But now the Problem is that i get micro stutters in my games. I especially notice it in Overwatch where i get 150 Fps on average and then it drops down to 90 Fps and it freezes for a very short time. And the same happens in The Witcher 3, normally about 70 Fps (Not in Cities) and then it drops to about 48 Fps and stutters.

I did a 3D Mark Test and got average results for both my CPU and GPU.
My CPU never exceeds the 78°C mark when running Prime 95 small FFTs.
When running Overwatch my CPU usage is constantly at 100%.

Things i tried already:
-Reset my Mobo to default setting, also did i set my GPU,CPU to stock settings.
-Reinstalled Display Drivers with DDU
-Used Windows repair function
-Updated all my drivers
-And after all that, installed Windows 7 AGAIN

Mainboard: Maximus V Gene
PSU: BE QUIET! Dark Power Pro P10, 750 Watt
RAM: KINGSTON HyperX FURY Red, 16GB @ 1600 Mhz
CPU: i5 3570K@4.5 Ghz, 1.24V (Raised from 1.21V, didn't help)
GPU: MSI GeForce GTX 1080 GAMING X 8G
Primary Monitor: Benq 2411T @ 144Hz
Secondary '': Acer P246H

Thanks for reading and i'll be glad for any responses.

  1. Hard drive is failing, please back up your data and replace it. Failing hard drive will cause boot manager errors.

    According to ark.intel.com, that CPU will thermal throttle at 67.4C... 78C is too hot. Please upgrade your CPU cooler.

    What is the make and model of the cooler you bought?

    What is the make and model of your current power supply?

    My Windows 7 is installed on my Samsung 840 EVO SSD, which should be working fine.

    Im using the Alphacool NexXxoS Cool Answer 240 LT/ST - Set, to cool my CPU. The Cpu never gets hotter than 70°C @ 4.5 Ghz, when playing Overwatch.
    I tried running the CPU at stock speed @ 3.8 Ghz, where the Temperature never exceeds 62°C when running Prime 95 FFTs stress test.

    The PSU i use is the BE QUIET! Dark Power Pro P10, 750 Watt as mentioned above.

    Thanks for your reply
  3. CPU is overheating. For a 240mm custom loop to have trouble with 77 watts, sounds like that kit is complete crap. The included CPU waterblock is so thin, IDK how it's doing anything at all.

    Moving on...

    The 840 EVO doesn't do well with repeated write operations. Do you use it for storage? How many times have you installed to it?

    His SSD is fine, and his CPU temps are fine. That CPU will not thottle until it hits 100 - you are confuing TCase with TJunction - please learn more before you try to help people.

    OP,

    Have you tried enabling VSYNC? That might be all you need to do.

    But when playing Overwatch the temp never goes higher than 62°C @ 3.8 Ghz, which is below the thermal throttle point.
    Could it be possible, that i tightened the CPU Block too hard and the thermal paste got forced off, so that it isnt between the CPU and the Copper Plate?

    I only store Windows 7 and my drivers on my 840 EVO, before all this stuttering started i had my Windows 7 on my SSD too and didnt have any problems then.

    I now enabled VSync and i feel like the microstutters are almost gone. My Fps are moving from 100-144 Fps tough.
    I also sometimes get a rather big Fps drop, where the stuttering is making the fps go all the way down to 60 fps, i played only 1 round so far and this happened once. Not to mention this did happen before too.
  7. Your CPU is not able to maintain 144FPS - that's the bottleneck.

    Im pretty sure my game ran smooth before the Overclocking fail tough. Could it be that my CPU got damaged when i tried overclocking it?

    Derp, you're right. Sorry for creating confusion.

    It's probably not damaged - CPUs can take a fair amount of abuse, and 4.5@1.2x volts is as safe as it gets. I'm not sure why it seems slower now. It does sound like you reset your BIOS settings at least once - did you change any of the performance-related settings?

    Yes i did reset my BIOS settings multiple times. I used this guide (https://rog.asus.com/7922012/overclocking/guide-overclocking-the-core-i5-3570k-to-4-5ghz-on-the-maximus-v-gene/) and i have applied all the settings used in this tutorial, the one thing i changed is the LLC to auto.

    I have however noticed, that if i set my Overwatch process from normal to high priority in the task manager i dont get any stutters anymore, but i dont really know why.
