Test System

Initial Setup

I installed the sticks into an ASUS P8P67 Pro, which I reviewed nearly a year ago. They match the board's color scheme very well, and a quick peek at the product page shows that it's on the list of supported products, too. As you can see, even on LGA 1155 products, the label is hidden from view and the sylized sticker is fully exposed, great for windowed cases and sales floor displays.


Each stick in the F3-2133C9Q-32GXH kit measures in at 39.6 mm, from the top of the heatsink, down to the edge of the 240 pins that get plugged into the motherboard.


That small size makes for great compatibility with most aftermarket heatsinks, as you can see in the two images above. There's several millimeters of clearance between the heatsink top and the lower fan of our Noctua NH-C14 cooler that overhangs the DIMM slots.


The G.Skill F3-2133C9Q-32GXH features an XMP v1.3 profile table, with the JEDEC settings clocking in at 1333 MHz, with 9-9-9-24 timings, using 1.5 V. Everything we found for timings was fairly standard, and should help the sticks boot in very nearly every motherboard. I certainly didn't have any issues.


The XMP profile is actually two different profiles, with the same primary timings, but different secondary timings, shown in the above and below pictures. Profile #1(XMP v1.3) has the slightly looser timings and worked best on out P9X79 Deluxe platform, as we found it had issues with cold booting with Profile #2(XMP v1.2) when the CPU was overclocked over 4.4 GHz.


Having two profiles actually makes a lot of sense, considering there might be situations where only two sticks of the kit might be run in a system, as advised on the product page. With just two sticks installed, we found we had not a single issue with cold-booting, so it seems that G.Skill really thought ahead about these sticks, and equipped them for every occasion.

Of course, because the G.Skill F3-2133C9Q-32GXH features an XMP v1.3 as well as an XMP v1.2 profile table, it is not only compatible with LGA1155 products, but LGA2011 products as well, so there are also hints that these sticks will be useful even if you intend to buy into LGA1155 now, and plan to move over to LGA2011 in the future, once other upcoming products have been released. Since I do all my testing on LGA2011 anyway, I'm about to find out. I personally didn't have any issues at all running all four sticks in my P8P67 PRO, although it did require a fairly reasonable boost to VCCIO voltage to be able to do so. Two sticks worked perfectly without any manual changes.
