Review: Corsair DHX vs. Kingston HyperX

Last week, we received the first Corsair DHX DDR3 memory kit and this was the opportunity to compare them against Kingston.

We wanted to include OCZ too, but all the sudden the kit stopped liking our motherboard  


The Corsair DHX modules comes with the patented DHX heatspreader which should provide better cooling and thus avoid overheating. We can say that the modules were noticable cooler than Kingston's, but we needed to increase the voltage to a dangerously high setting.


Corsair does not follow the lower latency delusion and our test proves that low latency does not necessarily mean more bandwidth .


The Kingston kit is specified to work at 1375MHz and comes with the ordinary blue heatspreader. While Corsair states the modules can go up to 1500Mhz, Kingston didn't make such a claim. With some overvoltage and additional cooling Kingston can match Corsair.


To overclock the kits properly we did some manual settings in the BIOS which is avoided during motherboard reviews.

If you want to buy such kits, make sure to set the following BIOS-setting on the P5K3 Deluxe/WIFI-AP:
DRAM Static Read Control: disabled
DRAM Dynamic Write Control: disabled
Transaction Booster: enabled
Boost: 1
CPU Spread Spectrum: disabled
PCIe Spread Spectrum: disabled
DRAM Voltage: 1333MHz/1500MHz, Corsair 1.50V/1.75V, Kingston 1.70V/1.90~1.95V
