Overlocking the i5 4690K

[vlatkovr]

Hi,

I have a few questions regarding ocerclocking the i5-4690k.

My system:
MB: Gigabyte GA-Z97-D3H
CPU: Intel Core i5-4690k
RAM: 8GB DDR3 g.skill f3-2400c10d-8gtx
SSD : Samsung 840 EVO 250GB

I have read many treads and I know that in order to overclock I need to increase the CPU multiplier (and after some time the voltage if it gets unstable).

However I have a few other questions:
1. Do I need to update the base clock or only the multiplier is enough?
2. What does 2400 mean for the memory. When I run the system without overclocking the memory will run at 1600 or? I mean the memory wont cause any issues for being too fast?
Also when overclocking (changing the multiplier) do I need to do anything to the memory?
3. From experience how far can I take it using the stock cooler?
4. From experience how far can I take it using a budget non stock cooler (and which one to recommend). And I mean budget (50$ for a cooler is not budget for me ). I have an 'arctic cooling freezer 7 PRO' for my old CPU but not sure if that one is compatible with the socket.

Thx

No updating base clock..
Yes memory will run @ 1600 without using XMP
No experience so can't answer stock vs overclock, but your old h/s & fan should work..

It's going to get toasty mighty fast with the stock cooler. I'm guessing this will limit your overclock achievements, if it forces the processor to throttle in the process.

I'd get a different cooler. At minimum, you'll get better temperatures with a Hyper 212 EVO. If you have a $50 limit, I recently discovered a heatpipe tower that never seemed to get a lot of attention when it was first released. It will perform 6C better than a Noctua D14.

The EVGA ACX cooler can be had for less than $55. If you want to spend more, there are AiO coolers.

If you want to squeeze blood out of a stone, a simple H80 single-fan cooler can do it if you attempt to follow a project in "Cases & Cooling" that uses a C70 computer case.

1: Don't bother with base clock. Since Sandy bridge it's just not worth the effort
2: Your mobo will support 2400 on the memory.
3: Stock cooler is good for stock speeds.
4: Your artic should fit. It's a decent 92mm cooler. I use a 92mm on my 4690k (xigmatek). At 4.4ghz on Prime 95 or linpak hour long runs hit low 80's C.

I'm coming around to a position in which I agree with the MonkeydelMagico.

On the one hand, the Haswell K chips are unlocked. They are "over-clockable."

ON the other hand, you can only squeeze out an extra two- or three-hundred Mhz for your overclocking efforts.

If that's what you want to do, you might want to look at WGusler's "Cases & Cooling" project with a C70 case and H80 cooler. The load temperatures on that system are about 10C lower than the Monkey's 4690K @ 4.4 -- around 70C @ 4.6.

WGusler concluded that he really didn't want to run the 4790K @ 4.6, and his temperatures at 4.4 were in the mid-50's C.

The stock cooler may be "sufficient," but you could do much better just for a $30 Hyper 212 EVO.
