Overclocking Xeon E5-2665

[Erlkoenig]

Hey folks.
I'm currently running a Xeon E5-2665 on an Asus Rampage Extreme IV. During next year I plan to switch for an I7 3930k or 4930k. Meanwhile I want to squeeze the max power out of this server chip, but I was just able to run on 105mhz baseclock. I'm not experienced in overclocking. So I hope you can help me. (Temps looking good and 600W PSU shall be enough)
Looking forward to pieces of advice.

You can't overclock the server processors. So whatever speed they come at is the speed they're at.

Yes I know. Non "K" or "X" Intel Processors have a fixed multiplier. (Mine is fixed on 24)
But there is a possibility to raise the overall clock. When you overclock the motherboard baseclock, which is multiplied with the CPU multiplier. Stock clock is 100 MHz. As I mentioned I where able to go for 105 MHz. That means 2,4ghz --> 2,52ghz for the CPU.
The point is, I have seen many others going for far more than just 105mhz. In my Bios are a bunch of Setting and I barely know the meaning of the multiplier and the core voltage. So I hoped I can get help here.

600w psu would be enough for most of the modern single gpu configuration. make sure you have decent cooler like noctua nh-d15s or if you can afford h100i v2 liquid cooler to keep system calm.

The CPU Temps in Idle are around 45 C°, spike at 63 C° (with 105mhz baseclock). The CPU cooler is a cheap one (Alpenföhn sth.), but performs decently I think. But when required I will get a liquid cooling system.

it will probably not enough when you use k series cpu due to higher voltage and frequency.

Yes i will See...
But Can anybody help me to get a little bit more out of this CPU ?
Which parameters I have to change in order to achieve a higher baseclock ?
