If anyone remembers the old X58 T1 kits from Kingston then they are in for a great surprise because Kingston just brought those heat spreaders back. Some people thought Kingston's T1 line was lost forever in a greater attempt to cut margins and sell more mainstream sticks, however that isn't the case.
The heat spreaders are a but tall, at least taller than the G.Skill TridentX kits.
The one issue we foresee is that these tall heatsinks might be an issue for big CPU heatsinks, as they are not removable.
Hynix CFR is an extremely popular IC for the Z77 platform because it is great at handling extremely high clocks. The majority of 2666 MHz and 2800 MHz kits one will see are based on Hynix CFR. TridentX kits are mostly Hynix with the exception of the 2600mhz TridentX being Samsung, Kingston themselves brought out some 2666mhz and 2800mhz kits based on Hynix CFR, but the issue with those is that they were single sided, thus unfit for benchmarking. The way the banks are accessed on modern platforms still requires double sided memory modules for the best performance, or else users can use 4 single sided sticks and have roughly the same performance as 2 double sided. The benefit of single sided memory is that it is usually easier to clock to higher frequencies, so if all you want to do is show off then they are good, they are also good if you can clock at least 100mhz higher than the double sided to regain that performance.
If one uses a watercooler then it isn't a big deal that the heatsinks are tall, they actually look nicer this way as well.
In the BIOS setup, one must go and select XMP or if they have a Z77 ROG board they can select a memory profile.
The memory profiles on Z77 ROG boards are extremely performance tuned. From our findings the XMP on this kit was extremely loose, and thus the Hynix Tight and Medium profiles actually won’t help you gain frequency as they are more aggressive than the XMP profile! We were able to use Hynix Medium for our attempt to tighten timings at 2400 MHz, and we did try to use RAW MHz profile for higher clocks, but XMP was actually a bit looser than RAW MHz profile when it came to secondary and tertiary timings.
Below is what you get if you load XMP Profile #1:
Please change the T2 to T1 as that is really what XMP should be, we think that ASUS BIOS auto sets T2 with dividers of 24x or higher for compatibility.
Also one must change CPU PLL OV to enable to easily utilize dividers of 24x and higher.
We booted with this XMP and easily passed, however that is T2. We will show you T1 later at this speed.
First some benchmarks:
There is a small difference in real performance, but a larger difference in memory performance. The truth is that the timings are just so loose at XMP with T2 to show much improvment from 1600mhz with cas 9.
