Hi, I have the following system:

Athlon x4 860K at 4.2GHz
MSI A88XM Gaming Motherboard
G.Skill Sniper 2133 MHz RAM
GTX 960 Graphics Card
Corsair H60 Liq. Cooler
Rosewill HIVE 750W PSU

My overclocking knowledge comes to an end once I get beyond increasing the CPU multiplier and the vcore. Right now I am at:
Multi: 42
vCore: increased to 1.4875v
CPU-NB: increased 1.375v
Thermal margin @ load: 22C
Turbo OFF

For some reason, I can't seem to be stable past 4.2 GHz. If I change the multi to 43, the vcore automatically (?) increases to 1.512v and I get a crash. Is there any other setting I can change to increase my OC and have it be stable? Thanks.

Thanks for your reply.
It wasn't the cooling that was holding me back. I assumed it was my lack of overclocking knowledge. I was hoping someone could advise me on what I needed to increase or change to get a couple hundred more MHz.
