As far as I can see, there are quite a few people having issues with OCZ ram getting it to run at its rated speed.
With ram that has a XMP when you activate this in the bois, does it have all the settings created for volts timmings etc etc and automaticaly run at the rated speed?

Generally yes (at least I've not come across it otherwise).
Mine for example is set to 1600 in XMP and 'auto' for the rest of the settings and runs perfectly stable.
 
Yes, an XMP profile will run the RAM stably at the timings and MHz advertised. It will set the RAM voltage too. The only thing I would be wary of is that the XMP profiles often leave the QPI/VVT voltage on auto which may default well above what it should be. (For example mine on Auto went to 1.54v, I've taken it down to 1.38 without any stability issues.)
 
Yeah the IMC voltage tends to be set pretty high by the XMP, mine was either 1.5 or 1.6 something.

Currently its at 1.113V and max advised by intel is 1.2 IIRC.
 
thing is im a bit miffed that my ocz will not run at its rated speed of 1600
1448 is what i can het it to now with a cpu clock of 3.6
can i be arded rma'ing it and being without for 4 days for the same of the difference in speed between 1448 and 1600
is there really any difference ?
 
Right my OCZ didn't even have XMP, so I had to set them manually. Presuming yours are CL 8-8-8-24 (CAS-TRCD-TRP-TRAS) your XMP should take care of this. The only other setting I had to enter was tRFC at 88 as recommended on OCZ Forum. Gigabyte board sets this a bit tighter. They only other things you should have to change are increase QPI/Vtt and set the correct Dram Voltage. Could I suggest you lose the CPU overclock and run Memtest on these first and get them stable. QPI/Vtt at 1.32V and DRAM at 1.64V
