So I’m torn between the OCZ3P1600LVAM4GK or OCZ3N1800SR4GK
I wanted to underclock the R4GK to get better timings and lower voltage, but it looks like this kit has more issues.
I see that the R4GK is supported on the Gigabyte’s list and the M4GK is not.
So I just wanted to get your options on these two kits.

So how can we hit 1333MHz speeds with CL5? I thought the fastest 1333MHz available was with CL6?

OCZ3P1600LVAM4GK is much better. They can do 1800mhz at those timings easily providing you're IMC can handle it (most AMD IMC can't handle 1500mhz+). They should be able to do 1700mhz @ 7-6-6-24 with 1.68v

In addition to that, they can clock pretty well with tighter timings. I'm running 6-6-5-20 with ease @ 1333mhz. I'm not very experienced in ram clocking but am getting better.

You need a very good kit, probably one of the Animal sets or another highly binned kit.

Generally, the IMC hits a limit on air at around 1650-1700MHz. This can however, be beaten through tuning drive strengths.

Updated and added a poll. I meant to put sticky but accidentally wrote stick, please forgive me, and I think you all should understand what I meant.

Bump for justice.

I would like to see sticky on this.

can i get a tl;dr plz

This was really a good guide buy Tony @ OCZ. I remember reading this over at the OCZ forums.

tl;dr: 1333mhz memory with tight timings and high northbridge frequency is better than 1600mhz with looser timings and stock northbridge frequency.

thanks! +rep
