Hi,
I am trying to Overclock my i7 3770k to 4.5 GHZ with the Asus Maximus V Formula MB and Hyper 212 EVO air cooler. This is a fairly standard combination of componentry so I would imagine there would be ample information out there but after reading countless threads there are simply too many variation so I thought I would make a thread. So basically this is what I did:
Changed the multiplier to 45
LLC to Ultra (75%)
CPU Voltage Frequency: Manual
CPU Fixed Frequency: 500
CPU Current Capability: 140%
So using these settings I was able to get 4.5 GHZ stable at 1.280 V but temperatures for 1 core reached 86C (other cores were around 73C) so I didnt like it so I scaled back down to 4.4GHZ which was stable at 1.272V and 83C. I then went to offset mode at +0.030V which leaves idle voltage at around 1.02V and load at 1.272V.
So here are the questions:
1. Why is 1 core (Core2) 10 degrees hotter than the others? For example Core 2 would be 39C at idle while the others are 30-33C
2. I know what LLC is but without much experience how can you tell how much LLC you need? Is it only by observing voltages during transition from idle to load?
3. Are my temperatures at OC potential for this chip fairly standard or do I have a bad one? Reason being some forums people report getting 4.5GHZ only on 1.19Vcore.
