Ivy Bridge - XMP2133/2400 issues

Hi all

Recently got some Kingston 2400 HyperX. My old RAM (1333) was causing some system issues so as part of a larger upgrade I got some of this.

I have read extensively about XMP, RAM timings, my specific board and CPU. However, nothing I do will allow me to boot at either XMP profile (2133 or 2400). I can manually set 2000mhz with 10 10 10 28 Auto 1T...which is the highest my CPU and IMC will let me. This is with 1.62VDRAM and a bump to IMC and VTT.

Have I just hit the IMC limit trying to get 2133 or 2400? Other reviews say my board (z77 d3h) and IB's can manage 2400. My i5 3450 is at 39/39/38/37 across the cores (maxed).

I am happy at 2000mhz as its a 20% increase in benchmarks over the old 1333 - but its frustrating I can't manage more!

Cheers
 
Thanks Tradesman1. I have also read this and can understand why. I have gone as far as possible on my 3450 which is 39/39/38/37 depending on core usage (most games its around 38). I guess then that 2133 RAM is probably happier at 4+.

I am at stable 2000 10 10 10 which seems fine so I will stick with it!

Worth noting for others - on these boards set Memory Performance to 'Normal' - Extreme favours timings over frequency and doesn't seem to let you go as far.

Cheers
