The Samsung will spend the rest of their life in my HTPC.
Ahh oh well, I guessed this when my second z77e-itx build did the same thing.
Also lucky you! Asrock's support email just told me to ask the seller, cheeky gits.
Do you think it's worth selling and buying a better kit for my HD 4000, considering that I already have 8-9-9-27 1866?EDIT:
Just found something very interesting.
When I set my Ram to 2000 in the bios, memtest flags this as 1333/2666, the higher settings do not post, and the lower settings (1866 etc) all show correctly in memtest.Set to 1866Set to 2000
I don't see anything wrong here. Remember DDR stands for dual data rate. Because of this you take the actual frequency and multiply it by two. So basically 933 is 1866 and 1333 is 2666. It should show up the same in cpuz.
Also, you guys need to understand that higher frequency does NOT equal more speed. It's a trade off. Higher frequency with higher (looser timings) can actually be slower than a lower frequency with tighter timings. For example 1866MHz with 9-9-9-24 timings will be slower than 1600MHz with 7-7-7-21 timings because even though there's less bandwidth, the clock cycles are more frequent.
