PC won't boot after RAM upgrade

OK so the new ram will run with the frequency set to 1600mhz. Which is an improvement on the old stuff as although that was 1600mhz ram, with my BIOS set at auto it was only running at 1333mhz.

The new ram is identified as 1867mhz, but will only run set manually at 1333 or 1600, on 1866 or auto it will not boot.

The old ram would run on auto or set manually at 1333,1600 or 1866, though at 1866, it boots with over clocking errors, which is to be expected.

On the basis of the above I think I will leave the new ram set at 1600 and go on with my life.

So I guess this has been a bit of a lesson in some respects, this should have been plug n play, but when things went south I knew bugger all about BIOS & CMOS settings, so although it has been a pain I have at least learned some things that will help me going forward.
 
It was never plug and play if there is no XMP profile. Plus there is no guarantee with OC'd ram past whatever the M/b considers OC'd.

The point is that you have to work for it to get it going, it is one of the finer points of overclocking.

With work you probably could get your old ram running at 1866 (maybe even a little more, depending.)

Look up some ram over clocking guides maybe?
 
have you tried searching for your ram timings and inputting them manually? I had to do it for a set of kingston hyper x when it didnt have XMP and always loaded up at 1333 as default.
 
I talked to a guy at work today about my issue and he said that my core i7 2700k only accepts ram up to 1600mhz. So that's the problem. Not sure what CPU you have. And I read up online that on this chipset, a higher frequency wouldn't help anyway
 
Yeah, following some further reasearch I think my CPU only supports 1333 &1600, although my mobo supports higher. As a noob I never considered the CPU, just what the mobo supported. That would explain why it won't boot on auto as the BIOS recognises it as 1866 and automatically sets it to that, and why it won't boot when manually set to 1866.

It's running fine now at 1600, not sure how much real world difference it makes between 1866 & 1600, it is also faster than the old stuff and it was cheap.

What I don't fully understand is how the old ram boot when set to 1866, possibly due to it being 1600mhz.

This is not true.

The truth is what speeds are supported.

You can get ram working faster.

My 2500k max supported ram is 1333, yet in all but one application my ram runs at 2133. In the odd application out, it runs at 1866.

You have to put the effort in, it is called... overclocking.

See above.
 
Cheers for the info, I accept that research may be required to get this ram up to speed, but as a novice I'm a bit apprehensive about tinkering too much. The timings stated on the ram of 10-11-10, I can see that what is showing also in the BIOS for the standard timings, then a whole load of advanced timings. I'm not sure where to start to be honest.
