OCZ DDR Booster Review
 

Today im looking at a wonderfully innovative product from OCZ which will prove very popular amongst the overclocking community, the OCZ DDR Booster Diagnostic device, which incorporates Powerclean Technology™ and Digital LED Readout. This device allows users to supply a cleaner power feed to their memory modules, which will result in more stable memory. Additionally the end user is now able to view memory module voltage with the digital LEDs on the DDR booster, allowing simple and inexpensive troubleshooting of their particular modules. The DDR booster allows VDIMM adjustments up to 3.9V and is compatible with a wide variety of DDR1 motherboards (see chart below).
