We are talking here proper performance memory and not 2133MHz which some vendors have the audacity to call overclocking RAM. As it is on with the Z77 landscape, overclocking memory can only be classified at 2,400MHz and above. After all, just about every set of 2133MHz memory can make 2,400MHz with some very relaxed timings and tweaking. So what does $459 earn you from AVEXIR? Well, it gives 22 The OverClocker Issue 22 | 2012 you the cheapest 16GB Quad Channel 2800MHz memory kit we are aware of. Every other competing kit is at least $599 and that $140 odd savings is a lot given that you can with that buy a 2,666MHz C10 kit from AVEXIR. Oddly enough that fact right there is one that made this kit much harder to endorse than ordinarily. Reason why that is the case is because this was easily the most difficult kit to overclock we had ever come across. We did manage to run the memory at the retail speeds but it took hours on end to get it right and some back and forth between motherboard vendors and us, sometimes for days on end. When we did eventually manage to stabilize the memory, we discovered that the XMP profile could not be used at all, and hand tuning of each setting was required. Disappointing given that, the whole purpose of such memory is to negate the need for such hand tuning at such high speeds. To put this into perspective, we had another AVEXIR 2,666MHz CL11 set with us and that set was very easy to clock to 2,800MHz. Simple adjustments of the primary settings were all that was needed and we were able to POST the system and run benchmarks for hours on end with no instability at 1.67V. That it proved more difficult to do this with a set rated at 2800MHz made us suspect perhaps AVEXIR had handed us the one kit in their inventory that just couldn’t pass the grade. Since overclocking wasn’t going to get us anywhere, we tried to tighten the timings and aim for better efficiency at lower speeds. Again the RAM left us wanting, as we weren’t really able to tighten the timings much to make this RAM a must have set as the 2,666MHz kit once again managed to not only match this kit but exceed it as well.
