Sabertooth Z77 / G.Skill Compatibility?

From what I understand, the ASUS Sabertooth Z77 board is extremely picky about the RAM it takes. I tried looking at the QVL, but it seemed kind of incomprehensible -- it listed RAM for speeds that the motherboard doesn't say it supports, and some speeds of RAM had almost nothing listed, or nothing listed for certain stick sizes.

Anyways, it says it supports 1866, but as I say the QVL was very restrictive. I decided to look at 1600, but even then, there are no 8GB sticks listed -- how would I be able to get to the full 32GB max if not by using 8GB sticks?

I found the G.SKILL Ripjaws X Series ( http://www.newegg.com/Product/Product.aspx?Item=N82E16820231568 ). For the time being, I'm looking at just sticking with 16GB with the possibility of upgrading. So, does anyone know if this RAM will work with this motherboard? Is there any reason to try to find 1866 RAM instead of 1600? If so, G.SKILL? Or others?

Basically, I'm pretty set on this motherboard, but I'm worried about getting RAM it'll reject.

I Had a similar question. Figured id ask instead of making a new post. The qvl on my x79 sabertooth doesnt support gskill 1866 4x8gb F3-1866C9Q-32GXM. cpu-z is showing this set-up as pc3-10700 667 mhz and the bios as 1066 i believe. Is this under light load, a lack of overclocking, or should i get something qualified?

Will G.SKILL Ripjaws X Series 8GB fit sabertooth z87 motherboard?

Hardstylle - what you are seeing in CPU-Z is probably the MAX BANDWIDTH box in the SPD tab - that is nothing more than the default boot freq of the sticks - to see what you are running, look in the memory tab, take the figure in the freq box times 2 (as this is DOUBLE data rate (DDR) for what it's running i.e. if it shows 800 then you are running 1600 effective, 933 indicates 1866, etc....for more on CPU-Z see my info thread here:

Also QVLs are pretty worthless as they test at the mobos default speed of 1333 or 1600, so if they show a 1866 set, it was only tested at 1333 or 1600...also they only test with whatever they have available and that can often be out of production sticks - for more on this see this thread:

You don't specify what model of Ripjaws X, but yes all sets that are of 4 sticks or less will run on the Z87 mobos - what you may want to check is clearance if you go to a third party CPU cooler that overhands the sticks - on that subject the EVO is a good choice as the fan height is adjustable

8GB (4GBx2)
CL9-9-9-24

Those should run OK, though the CPU calls for native 1600 DRAM - I'd give them a shot, if it seems sluggish all, these are great OCing sticks, manually set them to 1600, with base timings of 10-10-10-24, 2T and set DRAM voltage to 1.55....if any problem with that raise the CPUVTT to 1.1

-------------------
Sorry bout this but I replied in response to the 1333 sticks post (prob as you were doing the 1600 sticks post - the 1600's would be better and that set generally can go 1866 at 10-10-10-24 with the same voltage adjustments mentioned in the 1333 comments -if stable can try lowering the voltages but they are perfectly safe as shown
