Windows 7: BSOD After using ASUS Sabertooth 990FX MOBO OC Utility.

Just got home, let me check the settings now. I will get the bios version for you too.

Okay, yes the settings are all disabled. As for the BIOS, I said BIOS Version 0705, and at the bottom I saw V2.001201 Megatrend.

Quick update - I updated my BIOS to the most up to date current bios. BIOS 1604 for the ASUS Sabertooth 990FX. I put in the same settings you told me to put in the first time 1.4V for CPU, and 1.2V for NB and 1.650V for the RAM @ 1600MHZ. CPU ratio is at 21. The System is not reverting back to 3.0GHz during Prime95. It seems to be holding 4.2GHz strong, with Prime95. I'm running it for 20 mins to see how it does. Fingers crossed.

Update - Ran for 20 mins fine. No issues. Temps got as high as 55 C for socket, and 56 C for cores.

Nice 1
I'm glad the bios update fixed it, You were on a pretty early one.
Hopefully you should be sound now, I would normally say you could keep on trying if you wanted to go higher but your temps are close to the recomended maximum of 62c now.
Run Prime for a few hours to see if it holds out ok but remember that these stress test's are only synthetic and all they prove is that your system was stable enough to pass that stress test at the time. The only true test of stability is normal usage

If you want to increase your overclock you should improve your cpu cooling and airflow in your case. I recall you saying you were using a big 120mm and some 80mm fan's so that leads me to think you're using an old case which probably has little air flow as 80mm case fans don't move much air at all. The clearer the inside of your case is the more room there is for air to circulate and cool components but again you will be limited using 80mm fans.

Yes, sorry i had the wrong size fans when i mentioned what I had. This is what I have, COOLER MASTER HAF 922 RC-922M-KKN3-GP Black Steel + Plastic and Mesh Bezel ATX Mid Tower Computer Case with USB 3.0 and Black Interior - Newegg.com

2 200mm size fans and 1 x 120mm, and 1x 80(rear fan)

Nice 1 you have a decent case
I would swap out the 80mm for a 120mm though.

I have one, but i am not sure if it will fit in the rear

I believe the HAF 922 comes stock with a 120mm rear fan.

Thats what i thought

Let me check good sir! You guys are definitely awesome, for all the help you have given me.
