Kingston HyperX LoVo 1866MHz DDR3 4GB Memory Kit ReviewWed, May 05, 2010 - 12:00 AM
Finding a LoVo Ready Motherboard
We have a bunch of P55 motherboards here at Legit Reviews, but to be honest with you we didn’t have one that had the voltages going this low. Let’s face it when the Intel P55 chipset was created and the original BIOS designers didn’t know 1.25V memory kits were coming.
For example our Gigabyte P55A-UD6 motherboard would properly show the XMP memory profiles on our kit, but was unable to set the voltage down to 1.25V.
We loaded up the latest beta BIOS (F9d) and when we rebooted we noticed that the DRAM Voltage was at 1.312V and not 1.250V!
A quick look into the DRAM Voltage options menu and you’ll notice that the lowest possible setting on this specific motherboard is only 1.300V and it’s actually 1.312V. If you want to buy a Kingston HyperX Lovo memory kit or any low voltage DDR3 memory kit make sure the motherboard that you own or the motherboard that you are looking at buying is able to go that low.
After searching without luck for a P55 or H55 motherboard that was able to go down this low we ended up using the ASUS P6X58D Premium motherboard as it could go down to 1.20V. This motherboard also worked out better as changing from 1600MHz to 1866MHz didn’t require base clock bus frequency changes and it allowed us to better see the performance and power consumption changes of the memory kit. Our Intel Core i3-530 processor that we also tried to use for testing wouldn’t run at the base clocks needed for 1866MHz. If you had an Intel Core i5-860 or 870 processor you would have been fine, but we were originally going for low power consumption.
Let’s take a look at the final test system that we used to run the Kingston HyperX LoVo DDR3 memory kit.
