You won't go much further on a HyperX genesis, i know that because i use them and with a bit of ventilation they barely get even remotely warm.
Don't you have multipliers?

Idk I viewed this article http://www.bjorn3d.com/2010/08/kingston-hyperx-blu-4gb-kit-1600mhz-khx1600c9d3b1k2/#.UUu-3ra9Kc2 he raised te bclock to 200 which sounds unsafe
The presets is 1600 1333 1866 2133 blah

The best you can aim is 2133 MHz on a 2600k by modifying the RAM dividers. What you could try is tightening the timings. I'm running my 2600k's RAM @ 1866 MHz 9-9-9-24, and i can do 2133 MHz 9-10-9-27.

But yeah, SB and IB are pretty much locked with RAM, unlike Nehalem and C2D. They may be not as good, but IMHO, they're more fun to OC, especially the RAM.

Alsom, the website you linked shows those sticks being OC'd on a P55 Nehalem (socket 1156) platform. Almost all, if not all of those CPU's could be raised to 200 MHz BCLK since it was not tied to the PCI-E speed.

the 1866 is running @ 1.45v, and the 2133 MHz is at 1.51v. Mind you the RAM is different though (it's Samsung low voltage sticks, AKA. WonderRAM) and the base voltage is 1.35v.

You could try and raise the BCLK of your CPU to 102-103 MHz to get a few MHz off your RAM, but that may make any current OC unstable, either by vcore, RAM voltage or VTT voltage. Also, your chip may not like such modification (mine refuses to POST @ 104 MHz, and refuses to boot @ 103 MHz no matter what i do) so you might not even be able to OC the RAM that way.

Nehalem is more fun to OC RAM. My 1366 Xeon is running 1700 MHz 8-8-8-22 1.51v, and i even managed to boot 2050 MHz 9-9-9-24 @ 1.58v. Too bad Sandy isn't that flexible, it has a nice and strong IMC.

Core i5 750 = socket 1156 = 1st generation Core i5
Core i7 2600k = Socket 1155 = 2nd generation Core i7

Both CPU's work differently. The 1st generation worked in two parts, the "core" which are the... cores, and the L1+L2 caches, and the "uncore" which is the L3 cache, PCI-E bus and i think the IMC. Each of these two work using different multipliers, and even the base BCLK is higher than Sandy-based CPU's (133 MHz) and multipliers are very low (19-26x)

2nd and 3rd gen CPU's have everything working at the same speeds and not acting like separate entities, that is why the BCLK is the same speed as the PCI-E bus speed (100 MHz) but the multipliers are freakishly high (up to x56 on unlocked CPU's)

You might want to read about the differences on both architectures to know what you're dealing with, and why 200 MHz BCLK isn't doable on SB but it's a piece of cake on Nehalem.

The presets is 1600 1333 1866 2133 blah

Both CPU's work differently. The 1st generation worked in two parts, the "core" which are the... cores, and the L1+L2 caches, and the "uncore" which is the L3 cache, PCI-E bus and i think the IMC. Each of these two work using different multipliers, and even the base BCLK is higher than Sandy-based CPU's (133 MHz) and multipliers are very low (19-26x)

2nd and 3rd gen CPU's have everything working at the same speeds and not acting like separate entities, that is why the BCLK is the same speed as the PCI-E bus speed (100 MHz) but the multipliers are freakishly high (up to x56 on unlocked CPU's)

You might want to read about the differences on both architectures to know what you're dealing with, and why 200 MHz BCLK isn't doable on SB but it's a piece of cake on Nehalem.

^ explained well here. sockets 1156 & 1366 could pretty much all do well over 220 bclk with a good cpu, with a 2600k a bclk of even 110 is freakishly high.
For overclocking memory with sandy bridge, you have to use the mem multi, then when at the highest multi the memory will work with, some bclk can get it going a bit faster. The best I ever managed with a 2600k was about 2200 - 2240Mhz memory for benching.
