This is all I have to do to overclock my 2600k?

post #1 of 119
Thread Starter 
Using a 2600k, liquid cooled "custom loop" on a z68 board.
First, I have a FEW questions and please no story as an answer. I want to get 4.0 Ghz out of processor and use the 1600 Mhz memory at it's 1600 Mhz speed instead of 1333 Mhz.
Raise the multiplyer, and core clock and that's all?
As of right now my Multiplyer is x16 bus speed is at 99.8 Mhz and what's the x38 I see a lot?
I have read nearly every OC guide and it usually talks about something but doesn't say what it is, what it does, why it needs to be tweaked.

If one of you has a Z68 SLI can you please share with me what you did in your bios to overclock and and I need to do in general to get 4.0 Ghz? explain what I have to crank up, what it will affect, what it does.

To make your RAM run at the correct speed it should be as simple as setting the speed in the BIOS to 1600mhz.

About your processor:

Keep your Bus Speed as close to 100mhz as possible (IE dont touch it)

Your multiplier is 16 because of Speed Step (dynamically adjusts clock speed and voltage for power efficency). Im assuming you are looking at this information in CPU-z or similar?

To overclock (without messing with voltages to go higher), you can either change the multiplier for the turbo boost (the 38 you hear) or disable turbo and run at the overclocked speeds all the time.

If you want to get to 4ghz, its as simple as setting your turbo or processor multiplier (depending on which way you want to do it) to 40.

Shown here it shows 2 different multipliers, one is Turbo boost, one is base clock? So I disable turbo boost, go in to bios, amp up the multiplier which is x16 or x36? which one do I raise and to what?

And before I get started on that memory, I would like for 1 other to confirm no issues will arise please smile.gifthumb.gif


EDIT: It appears the multiplier switched to x16 as I took the SS, but the core voltage is different?
So I raise the multiplier to x40 and run some CPU strainer and I'm good? what about bus speeds?

Depends. I cant tell what multiplier you are talking about.

There will be two different ones:

One, for turbo boost. This is the multiplier that the CPU will be set at when running CPU heavy applications like games. Default this is x38

One for the actual CPU. This is the one that the CPU is set stock at. Default this is x34

What I would do is this:

Disable Speed Step and Turbo Boost (You can leave Speed Step if you so desire).

Change the CPU multiplier from 34 to 40.

Simple.

Overclocking to 4ghz wont need any voltage tweaks so you dont have to worry about that. thumb.gif

Just raise that bit? what is speed step?

From Wikipedia:
Quote:
SpeedStep is a trademark for a series of dynamic frequency scaling technologies built into some Intel microprocessors that allow the clock speed of the processor to be dynamically changed by software. This allows the processor to meet the instantaneous performance needs of the operation being performed, while minimizing power draw and heat dissipation.

Basically it lowers your multiplier based on how much load is on the CPU.

Turbo Boost is basically the same thing but it raises your multiplier instead of lowering it.

not sure how thoroughly you've read the guides...

here's a basic one for evga motherboards; http://www.evga.com/forums/tm.aspx?m=1033200

It's at 3.4 ghz still, I did EVERYTHING he said on the EVGA forum. Except it won't go 4.0 unless turbo is enabled. How do I do it so it will go to 4.0 all the time?

Will that keep me at 4.0 all the time?


EDITT: when I tried changing the ram dimm voltage, it said "1500" instead of 1.500 or 1.5 is that normal? My voltage is 1.50
