DDR3 RAM NOT running at 2133MHz XMP

Hey,

Recently I upgraded my ram from 16GB of Corsair Vengeance 1600MHz to 16GB of Muskin Blackline 2133MHz RAM.

Now my motherboard (MSI p67a-gd53 b3) on the latest BIOS wont run the XMP profile which is at 2133MHz. I mean the PC wont load at all (just restarts itself) - it wont even boot into the BIOS. I checked online at it says the motherboard supports up to 2133MHz. I have to clear CMOS to get back into the BIOS because when I activate XMP the PC will just restart itself. By the way the ram is rated at 1.5V which I think plays apart in why the PC wont even boot into the BIOS when XMP is activated because I think its not enough voltage at the older LGA1155 chipset.

However when I manually set the DRAM frequency to 2133MHz and manally set the RAM Voltage to 1.655V the PC loads into the BIOS and recognises the 2133MHz OC but when I try to boot into the OS it come up with a black screen saying hardware changed and wont boot into the PC.

Now when I activate XMP, manually set the DRAM voltage to 1.655V; it boots into the BIOS fine and recognises the OC perfectly. And it also recognises Windows and boots into windows but as soon as the OS is loaded I am greeted with a blue screen which is better progress than the black screen but now I am blue screening

When I run the at 1833MHz and 1.65V (even though the RAM is rated at 1.5V) the BIOS and PC run perfectly and it runs fine under a stress test of Prime95 using my 4.5GHz OC on the CPU, but as I said this is 2133MHz RAM and I want to run it at those speeds becasue I spent £85 on the RAM.

I have turnt off my overclock on the i5 2500k so its on stock speeds and stock CPU voltages to eliminate the CPU OC being a factor and I have the latest BIOS (4.3). I am also using an RX 480 and an SSD to boot windows.

This should be enough information for you guys to go on and I hope we can get this issue fixed soon :)

Is it 4x4GB or 2x8GB?

There are 2 variations of Mushkin blackline pc3-1700, one set runs at 1.5v and the other runs at 1.575v. You can tell the difference between them by the heat sink used. 1.5v has semi circle notches out the top, where the 1.575v are straight notches similar to corsair vengeance.

Semicircle notches. So 16gb (2*8gb). It's rated at 1.5 volts on the box it says. This is the ram https://www.google.co.uk/search?q=m...AUICCgC&biw=360&bih=560#imgrc=ftkPZyocnnHE0M:

your running an i5 2500k right? sandy's max is 2133mhz

i had the same problem years ago dude

This is most likely your problem, anything from 1866 I've seen have major issues. Gets even worse when you use 4 sticks of RAM. I wouldn't personally run the RAM too far over its rated voltage. Have you tried increasing the memory controller voltage to see if that helps stabilise the speeds?

How would I go about doing that. So its not the RAM that is faulty which is good news. There are plenty of people running 2133MHz RAM on the i5 2500k so it cleary works on it.

it's locked the the cpu from what i remember, you'll need an ivy bridge cpu to go 2133mhz+
 
You are probably limited by your CPUs memory controller. So you'll have to manually OC it like killbane said and increase the CPUs memory voltage. I can't tell you what it is called in your BIOS, being so long ago and terms always changing I couldn't remember.

But tbh I haven't seen many people from Ivy and earlier being able to run higher memory speeds. Wasn't really till Haswell that we started to see better results.

I'll increase voltages to 1.65V but I'm not sure how to OC memory contoller NBD? Like I have never even heard of it before today imo :D

EDIT: The thing is it says it supports 2133MHz ram and I have seen plenty of people run 2133MHz ram so I am so confused on why its not working for me tbh.

Just done some more testing. When I use one stick which is 8GB at the XMP profile which is 2133 @ 1.5V it is perfect. As soon as the second stick goes in, then it becomes a problem

Then that will be down to the memory controller on the CPU I would have thought.

In what way? Do I need to OC the memory controller and how do I do that because I have no idea (I have never touched the memory controller, I always use XMP) or do I need a new motherboard (it says it supports 2133)

Yeah you need to raise the voltage then. Hard to help, we don't know the BIOS
 
Judging by the sounds of things I might have to cut my losses and run it at 1866 using tighter timings at 1.53 volts which is safe

It won't make a huge difference. I would also go easy on the CPU and board, given their age (capacitor wear etc).

Going balls to the wall on everything will gain you about 10%. It's really not worth it.

Very true. I managed to get timings down to 10-10-10-25 from its original 11-13-13-31 @ 1.53 volts using 1866MHz

I mean it is unfortunate that I can't run it at 2133 after spending that amount of money on it but I have my old ram on eBay. Hopefully it will sell fine which will soften the blow of how much I spent on the RAM. Anyways a stable system is better than no system at all. I have my CPU back to 4.5GHz as well using 1866 which is a plus.
