    Default Z68XP-UD3-iSSD tips

    I'm somewhat of an enthusiast, but haven't built a system in a few years. I've been using Gigabyte boards & products on my last few machines with great success, even converting some friends over from Asus. I recently built the following setup:

    i5 2500k
    8 GB Mushkin Redline 2133
    2x Mushkin Chronos 120GB SSD's (Raid 0)
    Radeon 6950 2GB
    Antec 750 Tru-Power
    Corsair H80 CPU cooler

    I had a lot of stability problems when I tried to run the XM profile built in to the memory, so I dialed the memory FSB back down to 1333 mhz. I turned off the turbo mode and am running the CPU at a base 3.2 Ghz. I think that some of my issues relate to the SSD's and can RMA those if needed. I'm using the onboard 20GB SSD as a cache drive for my data HDD, which I realize is mostly useless. I could use this drive for something else. The RAID array is my system / main drive

    My last computer was a Core 2 Duo setup. I understood how to work with the multiplier, memory FSB and voltage settings to do some mild over clocking. When I look at the BIOS in this thing, it's completely new with levels and all kinds of things that I don't understand. Before giving up my manhood to a software program for overclocking, I'd like to understand how things work and what I can do to help things along.

    Can someone give me a few pointers on overclocking an i5 setup, what's key to keeping stability, or point me go a good guide to go through it?

    first is not to oc with the bclk,keep that at 100,do all coverclocking with the cpu multiplier,dram can be no higher than 1.5750v and qpi/vtt for the integrated memory controller inside the cpu no higher than 1.2v,usually stock 1.05v is fine

    cpu voltage is applied through voltage offset or in gigabytes case dvid,you can see the stock voltage that the cpu uses in the bios and dvid applies what you set in it for example +0.01000v at load so stock cpu voltage of 1.9000v will be 1.2000v with dvid applied

    next hardest thing is to work out each level of llc (loadline calibration) and how much each level adds to the cpu voltage at load to stop is drooping

    for 4.5ghh/4.6ghz usually around 1.36v is needed,maybe less with a 2500k on account of no multithreading

    I think the memories are okay, but loading the xmp profile and setting them to 2133 is probably too much for the memory controller. Mine is strugling to get to 1866 with 1.2v qpi/vtt. Many others have also reported weaker memcontrollers lately. I'd advice to start off at 1600 and see if you can get that steady.

    I did get the cpu @ 45x turbo fairly easy, by just letting auto set the voltages and only setting the turbo multipliers to 45x. Photo Album - Imgur

    also 45x (always high, no powerstates) was not to dificult: in advanced cpu core features auto, auto, and the rest disabled, then in advanced frequency settings put multi at 45x. In the voltage settings I have 1.29v and LLC level 6, but you may have to find your own sweetspot as not all cpu's will reach 4500 @ 1,3v (load)

    Also, see Miahallen's Guides here for an in-depth walk through on Sandy Bridge overclocking
    Gulftown, Bloomfield, Lynnfield, Clarkdale, SB Overclocking Guides (1155/1156/1366)

    I agree with Darkje, not all CPU's easily do 2133 with 4GB modules (XMP = easy), most will do it with manual settings, but you may need to learn a little more about tweaking first. Mainly you need to find out what voltages for the IMC (System Agent) and QPI/Vtt your CPU likes and needs at a given memory freq. You might need to use 1.1-1.2ish for QPI/Vtt, and 1.0-1.24 for the System Agent, to get 2133 going. And of course you'll need to set the main memory voltage to spec manually as well.

    I can help you with the memory once you get all your other overclock sorted and stable where you want it, I'd say set the memory to 1600 for now as Darkje mentioned, then you can try to raise it last.

    Be sure you have your SSD RAID on the first two Intel ports (White 6Gb/s ports).
