BIOS Troubleshooting

[JoshTheTrix]

Hey guys!

 

For a while I had my 6600k OC'd to 4.6ghz and I had an XMP profile on my memory to bring it from 2133 to 2667. Its usually stable, I've had some crashes in the past but for the most part its stable but today I booted up my PC and it would not post. The error code LED read 99 and it wouldnt post until I reset the CMOS. I tried to get my CPU back up to 4.6 but I had to dial it back to 4.4 to get it to boot into windows without freezing. Even still when I tried to play games, they would crash. If anyone has any idea what's going on I'd love some insight. 

 

Thanks!

CPU unstable probably. Give it some more voltage

Assuming you live in the northern hemisphere then it's summer and that usually means higher ambient temperatures, it's not unusual for OCs that have worked for months to suddenly become unstable in the summer.

That could be true, however, I've had this config for a number of years and never at any specific time seen this issue before. My h100i keeps it icy cold according to nzxt cam

What voltage(s) are you using?

Have you updates your BIOS recently?

Did you re-seat the CPU block, or re-apply thermal paste lately?

 

It could be that the CPU had degraded a tiny bit, and will require more voltage to keep your 4.6 GHz overclock stable -- this would be the worst case...more or less.
