I have tried manually setting it to 2133 and using the xmp profiles and I am still getting crashes every few hours :(

I am trying to get my ram to the speed it is supposed to be at. I have Gskill Ripjaws 2133mhz and they default at 1600. 4 x 4gb.

I was reading up on how to do it and it said to use the xmp profile in the bios, my bios has 2 xmp profiles but when I select either I am getting random crashes.

I also tried manually setting it to 2133 and changed voltage between the recommended 1.5v-1.6v and read on the gskill site that you can go up to 1.65v but I am still getting crashes.

If anyone could give me any advice I would really appreciate it.

without going into the details of the mobo, what speeds it supports and if that particular memory is compatible... (i leave this check to you...)

XMP means that the memory is overclocked to the speeds advertised by the profiles.
Default DDR3 specification is 1600MHz.

The fact that you cannot reach 2133, it could be due to the following most encountered problems (maybe others can point out additional ones):
1) faulty memory - try to run memtest86+ using various combinations (1 stick, 2, the other 2, etc) - this should point problems also in default speed. If in default speed is ok, but in xmp you have errors, then you have to apply lower speed or default

2) mobo z87 does not support properly 4 sticks at highest memory speed. I had situation where 1 pair of 2 sticks was working fine at top advertised speed, but 4 of them had to go 1 speed lower.

3) the sticks are mixed and matched - you bought 2 sticks at a point and other 2 sticks later - it could be that although the specs are same, the chips or detail timings are different... in short they are not meant to be put together and still work at the highest speed in such combinations.

4) unstable PSU when overclocking (not necessarily is reaching a wattage limit, but it could be unstable or have noise, messing the motherboard and creating instability)

Thanks for your suggestions.

The ram worked fine at default 1600mhz, never had a problem so I don't think the ram is faulty, I assumed it was something I was doing wrong in the bios. (I'm not in any way an expert) I will try memtest86+ someday when I have time.

The motherboard supports up to 3000mhz, but I am not sure if that is the case for 4 sticks as you say.

I did buy the sticks separately but I still have the packaging for both and they have the same model numbers and timings, which I made sure were the same when I bought them.

PSU seems fine, never had any problems with it.

I am thinking of just leaving it at the default 1600 as I've read it wouldn't be much of a noticeable increase but was just hoping I could get it to where it can be without too much hassle.

Thanks again.

The memory controller is a part of the CPU

It it not rated for 2133, you are therefore overclocking it so that it will work at 2133, if it cannot cope (luck of the draw) then you'll get the symptoms you are describing, all three elements (mobo, ram and CPU) have to be capable for a specific speed else you'll be overclocking the worst part.

@13th monkey, I think you might be right. I did a quick search and found this:

"The Intel Haswell microprocessors are only rated to dual-channel DDR3-1600, and this is what they are tested for. However, it is possible to exceed this if you're willing to make a few sacrifices. Some microprocessors will be duds, but I've never seen one that can't exceed DDR3-2400 with a little bit of work. I've seen a few low end Sandybridge i3 microprocessors which couldn't exceed DDR3-2000, but that was several years ago.

The DDR3-1600 rating is the point that Intel feels the microprocessor will meet a certain level of data stability. If stability is not of paramount concern, speeds above this may be obtained at the cost of a slight amount of stability over time. The memory may appear to be completely stable from a functional standpoint, but you may experience a few odd crashes that just can't be explained. Maybe two or three a year, nothing to worry about as a gamer.

Most of the time, all that's needed to get it "stable enough" for speeds at or under DDR3-2133 is enabling the XMP profile. If more than one DIMM is used per channel, the voltage to the memory controller and PLL may need to be increased by between 50 mV and 100 mV, this is necessary for my microprocessor.

As for the performance increase, it will be slight and it will be very case by case but it will be there. I'm told by a couple of other folks around here that the Haswell microprocessors in particular do like high speed memory."

So i'm thinking I should set the xmp profile and up the voltage to the memory controller and PLL.

I don't see DDRVTT or CPUVTT. I have included an imgur link of bios screenshots and would appreciate if someone could tell me what I need to raise for the memory controller. I see VCCIN and had read it was the amount of power sent from the motherboard to the processor. Is that the only thing I need to raise?
Sorry for being so clueless but I appreciate the help everyone.

When I increase it by +0.05 to 0.898v the number turns red. Is that a warning not to go that high or just a precaution and it is safe to operate at that voltage?

edit: I realised after i wrote this that you meant change the offset mode to + and change the voltage offset to 0.05. I tried this and it crashed after around half an hour or so 🙁
