I5 750 Overclocking - RAM questions - TOTAL NEWB


I'm never overclocked before. In fact I've never even been in the BIOS. However I've been doing some research and I'm going to give it a shot. Right now I'm just picking out my PC parts. I'm almost set on my build, but I'm unsure on the RAM.

Anyway.. here are the CPU, Mobo and RAM I've selected.

CPU: Intel Core i5 750 - $196 -

Motherboard: Gigabyte P55-UD3 - $135 -

RAM: G.SKILL F3-12800CL9D-4GBRL Ripjaws PC3-12800 4GB 2X2GB DDR3-1600 (2 of them, 8GB total) - $200 -

I'm also getting a Coolermaster Hyper 212 Plus and 2 extra fans to help with cooling. I'm looking to overclock to a stable, cool 3.6ghz.


OK, so my concerns with the RAM is this. I want 8GB of RAM for sure. The 3D software I use is a RAM eater, with others saying it can use up to 9GB even during rendering. The problem with this is that I have to fill up all four memory slots, which I've read can cause instability? Does using 8gb affect the settings I input in the BIOS when overclocking? I'm going off of newbie Overclocking guides.. so any extra variables are making me nervous.

Also.. it seems in the reviews for this RAM that people say that the i5 750 will only recognize 1333 of the 1600 mhz. They say you can change it, but they don't say how!

I really just wish I could find someone with my exact same hardware and copy their settings. I'm ready to just give up and not overclock. :( All of these numbers and settings are quite confusing.

Right now I'm thinking I'll just copy this tutorial: | Can anyone speak on the correctness of that tutorial?

I'm basically just looking for some guidance. Any help would be much appreciated. Thank you! :hello:

  1. get the P55A ud3 model i believe it doesnt have foxxcon sockets which can blow out when you overclock.

    YEAH, watch out for those blow out overclocks, they get all over the walls and the carpet, it's a real mess :lol:

    By the way the P55A boards DO have Foxconn sockets and unless your doing VERY extreme overclocking it's a total NON-ISSUE.

    @OP, First of all check out some competent guides that explain things to you, like what VTT/IOH/PLL/PCH etc. are so you have an idea of what you are changing in your Bios.
    The ram will only go to 1333 when left at stock speed, when you OC the Bclk you increase the memory also. The max memory multiplier (for a 750) is 10x so depending on how far you OC it you could possibly go to over 2000 Mhz. And YES populating all memory slots makes it harder to stabilize but that just means a little more trial and error when you are OCing it.
