In the case that anyone still cared, or runs into this with the same issue; I've resolved it. When installing my M5A78L-M PLUS I used the VRM heat-sink as a handle. This caused it to shift and feel much looser. When I attempted a small overclock, 3.8GHz the temps would go up to 54 and throttle my CPU. This was happening even though the actual CPU was running at 30*c. To resolve this I went investigating. Opened up my PC and removed the GPU for better access to my VRM heat-sink. It was able to wobble back and forth. I attempted to remove the heat-sink. It has small push pins that you have to squeeze from the back. (I was able to do this without removing the mobo from the case) After removing the heat-sink I immediately found my issue; not only was it loose but the thermal paste was rock hard. It is strange because I bought this mobo brand new and it was only released in 2016. Cleaned the old thermal paste off with 99% isopropyl alcohol. Reapplied a small amount of thermal paste, Arctic MX-4 2019. I put the heat-sink back on and it sat much more snugly. And that's it, looks like I just received a semi-defective board. All is in working order now and I am able to run on a 4.0GHz clock with no problems. Going to try the 4.2GHz sometime. Here is a picture of under the heat-sink. If anyone can confirm this is the VRM? Anyways, setting myself as the one who figured it out! Incase you notice my 12V showing as 10.4V in HWInfo I'm not sure why it does that, but BIOS says 12V is fine.

Okay, so I’m going to double check this later today. May have found the issue When I was installing my MoBo this past day I was plugging stuff in and felt something go on my VRM Heatsink (Yes I was using heatsink as a handle) I felt the VRM heatsink under load and that must be the CPU temp on the mobo. It does feel loose and moves back and forth. When I get home today i’m going to check on the push pins make sure that it is fully seated.

Sadly, I believe I've solved my issue. Reset my OC settings and it will now sit around 47*C. Going to try a 3.8GHz clock at least to get some power out.

I'm a dumbass! I'm not sure why its reading 10.5V there but 12V on BIOS. Not sure which to trust but obviously thats not a good thing.

Checked out my 12V and it is doing great. Turned on Turbo mode for CPU and Chassis fans. Not sure this will do much, but better than standard mode I guess. Also turned Turbo Core to Auto instead of disabled incase this was the issue.

I'll double check BIOS but I believe I saw the 12V running at 12V (A bit above actually) Do you mean the CPU fan specifically or case fans in general? I've got one 120MM intake through the front and another 120MM exhausting out the back. Both are connected to a fan splitter. The CPU cooler run directly in this path aswell, should be pretty cool in there. Pic below FYI: That CPU temp at idle is around 43*C is it possible too much thermal paste is the answer (Please call me an idiot if this is not the case at all)

Woops! Sorry about the mix up. Checked out out HWInfo (SO much better than the other one btw) Screenshot attached Looks like the temp listed (the 50*C one) as CPU correlates with the TMPIN0 to the dot. What exactly is that temp reading? Since its the CPU temp read off the MB and not the one off the actual CPU. Also still confused as to why its throttling at 53*C? That isn't that hot is it?

Thanks for the quick reply! Yes in the screenshot it shows another TMPIN1 but it does not get the temps TMPIN0 gets. Aswell When the drops occur my CPU temps drop weirdly low, around 23*C while being 100% usage and stressed. so weird

Hello all, CPU: AMD FX-8300 3.3 GHz 8-Core Processor CPU Cooler: Cooler Master Hyper 212 EVO Motherboard: Asus M5A78L-M PLUS/USB3 Micro ATX Memory: Kingston HyperX Fury Black 16 GB (2 x 8 GB) DDR3-1600 Memory Storage: Crucial BX500 240 GB 2.5" Solid State Drive Video Card: Gigabyte Radeon RX 570 4 GB Gaming 4G Case: Corsair SPEC-02 ATX Mid Tower Case Power Supply: Corsair Enthusiast 650 W 80+ Certified ATX Power Supply I recently put a new motherboard din my PC to try out overclocking. I've ran into an issue when benching. The CPU runs great for a while until something called TMPIN0 hit 54*C in HWMonitor and GHz drop to 1.4 (Clocked to 4.1) Can anyone tell me what that is reading? And why it would be reading so low? From what I understand the GHz drop is my CPU thermal throttling but 54*c doesn't sound that bad? Stressing my CPU with CPU-Z Actual CPU temps look fine, never getting north of 45*C Confused as to why my CU would be thermal throttling? Is that readout possibly my VRM? It has a heat-sink and good airflow

Hi all! Thank you all for the help. Just ordered a ASUS M5A78L-M Plus 760G. Should work great with my build and unlock overclocking! (Plus work payed for half of it ) I'll update this thread with my final thoughts on the board Thank you, Ruk

So, with my clock speeds, however low, now being consistent. With all the power management in the world turned off, I'm left the simple fact that I can't increase the clock speeds with this mobo and CPU. -This should be caused by the fact I'm using a mobo from a crappy ASUS prebuilt So, I should just invest in a new mobo and then be able to increase CPU clock speeds. Looking into mobos now.

Doing that currently, so far so good. This is super easy with ASUS EZ. BIOS was out of date, found a version from 2015

Okay so I messed around some more. Disabled all power saving options in BIOS and disabled HPET in BIOS, enabled in Windows. It no longer stutters the Ghz but now just sits consistently low. I guess now I need to increase clock speeds? It sits at 3.28Ghz even though right next to it, it states Base Clock: 3.31Ghz. So next step is increasing my clock I assume? My CPU temps are so low I feel like I could increase this quite a bit. temps for CPu in game around 40-45*C Let me know if I shouldn't be oevrclocking with my current setup, or the easiest way to? Checked and could not find any Turbo options in BIOS, not sur eif my MoBo + CPU has that. (Its running in performance more is BIOS) Update: Stressing the CPU with CPU-Z it still refuses to increase clock speeds, is this what I should be expecting? I see no voltage options in BIOS so I assume my Mobo sucks so bad it can't OC my CPU?

More investigation. I've discovered my issues, just need to know how to fix them now. My CPU throttles hard while in game. Dropping to 1.4Ghz and destroying my frames. I've checked all my power options. AMD settings and Windows. What could be causing my CPU to shit the bed so hard?

Hello all, Looking for a new motherboard to put in my rig as my old one is an M52BC from a prebuilt. This is the build the mobo will go into: PCPartPicker Part List: https://ca.pcpartpicker.com/list/kyMFWD CPU: AMD FX-8300 3.3 GHz 8-Core Processor CPU Cooler: Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler ($34.99 @ Memory Express) Memory: Kingston HyperX Fury Black 16 GB (2 x 8 GB) DDR3-1600 Memory Storage: Crucial BX500 240 GB 2.5" Solid State Drive ($41.95 @ Vuugo) Video Card: Gigabyte Radeon RX 570 4 GB Gaming 4G Video Card ($159.00 @ Canada Computers) Case: Corsair SPEC-02 ATX Mid Tower Case ($206.73 @ Amazon Canada) Power Supply: Corsair Enthusiast 650 W 80+ Certified ATX Power Supply Not looking to upgrade to AM4 and DDR4 as that would involve most of my parts being replaced. Any good AM3 DDR3 would be amazing, thank you! UPDATE: This seems to be a good option https://www.newegg.ca/p/N82E16813128602 GIGABYTE GA-970A-DS3P (rev. 2.0) AM3+ AMD 970 From reading the specs it looks like it would fit well into my build.
