Significantly slower POST after failed OC

Recently swapped out my old heatsink for a newer one. With this I felt necessary to OC my CPU. I tried a few times but none were perfect. Eventually it decided to freeze on a prime95 test and upon restart there was no display yet all hardware's fans were running. I decided to shut down unplug the power and retry. This time it started but the POST was around 10-15 seconds rather than the usual 3-5 seconds. After post it will either boot windows, freeze on the bios intro screen, or have no display. When it does actually boot to Windows (which only happens after unplugging the power cable for a few seconds) the fans start at a slow speed on the 10-15 second POST and then kick in to full power at its regular RPMs. in BIOS it claims I only have 4080mb of ram when I have 8gb total (4x 2gb) and speccy claims I have 8gb of ram but its single channel. There is also no beep on startup but I don't believe there has been for quite a while.

Things I've tried already:
MemOK
resetting cmos via pins
hitting the tower
resetting bios

SPECS:
CPU: AMD Vishera 8320 8 Core Processor
MOBO: Asus M5A99x EVO R2.0
RAM: 8GB GSKILL Ripjaw
GPU: XFX Radeon 7970 Double D
HDD Seagate ST2000DM

UPDATE:
Flashbacked the BIOS and now it is recognizing the RAM as 8GB Dual Channel
So now the issue is the POST is still taking longer than normal, it starts fans up at slow speed, then after about 5 seconds it kicks in to regular fan speed and the display and appliances turn on.

EDIT: I forgot to set the RAM, ignore previous mention of it in this post

UPDATE: Back to square one. After 2 consecutive crashes (Frozen screen with buzzing audio w/o error message) my ram is once again set to 8gb single channel.

UPDATE:Updated the BIOS. All RAM timings are correct and it hasn't crashed yet, but the POST is still taking longer and pauses on the memory portion for about 1-2 seconds and then cycles through.

You can also try flashing the BIOS to the latest version. If you already have the latest version, flashing it again might help if the BIOS was corrupted some. Have seen this before and flashing the current BIOS version again sometimes straightens out some problems that have developed. After flashing you will need to boot into bios and set it all up again, especially the memory timings & speed.

Disregard my previous version of this post. I got the RAM set to 9-9-9-24 as it should be, however the POST is still talking 3-5 seconds. Maybe I am just taking this issue as something major when it doesn't really matter. Regardless, the red lights indicating the hardware check seem to cycle through twice. I am at a loss for what to do but buy a new MOBO.

Is your HDD in the same port that it was originally. If not put it back. In BIOS, make sure it is the first boot device. If there is an option for the first video device, make sure it is set to the PCIe slot.

Did you set the optimized defaults in BIOS? This should be done before setting any of it up again.

Yes everything was set to optimized defaults then the RAM timings were set. The HDD was not touched and still is the primary boot device. Also it's not only the display that doesn't turn on right away, any USB devices including the keyboard and mouse are unavailable even with the settings in BIOS that enable them for POST. When it flashes the red lights on startup it spends a second or two with a stable red light on the memory portion and then proceeds to cycle. I can upload a video of the case on startup if that would help.

Fast boot is on and has always been.



Will try that now. Updates soon to come.

2 yellow markers on USB controllers, other than that no. It recognizes my mouse and keyboard under the mouse and keyboard section. The display is also recognized. POST is still about the same speed and there is still no beep, red light still holds on memory for 1-2 seconds. Am I just making a big deal of nothing? It really doesn't seem like much is wrong but I haven't really had my computer under any sort of load since it crashed other than CS:GO for about 20 minutes. But if there is something wrong I'd like to fix it.
