Now 250mhz is nice. Very nice actually. But could we really call ourselves hardcore if we settled for the status quo? Traditionally both OCZ and HyperX are known as good overclocking memory, most times able to run above their printed specs. With unlocked P4 processor in hand I couldn't wait to see just how high these chips would run. In the end I was both very pleased and sadly disappointed.

It would seem that the dual sided Samsung chips used in the HyperX modules are at the very end of their rope.  Heck I'm actually quite surprised that they were able to run 250mhz at only 2.6V. No matter what settings I used or how far I bumped up the voltage I absolutely could not get this memory to even post at anything past 252mhz. With the newest HyperX PC4000 sets being shipped with Hynix ram chips though you might have better luck with a newer pair.

As for the OCZ memory, this stuff is amazing! Not only was I able to get it to run stable at 275mhz, but I was able to do so at the reduced latency settings of 2.5-4-4-7, which just so happens to be the specs for the "Gold" version of this RAM. I'm quite sure that it can do higher as well since I was limited by the IS7's max DRAM voltage of 2.8V (which is stock for this pair). In fact, our editor in chief reports that he was able to take this same memory to 281mhz (effective 560mhz) at 2.9V on a Lanparty Pro 875B setup. OCZ is obviously once again living up to its reputation as the fastest performing DDR memory on the market.

Quite simply, if you have a P4 800mhz based system and want to reach that magical FSB speed of 1Ghz, than either of these two sets of memory would be perfect for you. If, however, you have a bad ass cooling setup, a high end overclocking board, and want to take your P4 as far as it can go, have a look at some OCZ PC4000. With the ability to hit 550mhz at 2.5-4-4-7 on stock setting, this indeed be some Bad Mama Jama RAM!

OCZ EL PC4000 Final Score: 95%

Kingston HyperX PC4000 Final Score: 89%

  • OCZ hitting 562mhz at 2.9V, 550mhz stock
  • 565mhz!!! nuff said
  • Awesome price on the OCZ considering how well it performs

  • Dual Channel doesn't translate to real world results
  • Weak Kingston overclocking
