Phoronix posted a review on the GeIL Value DDR2-1000MHz memory

Last year we had the Ultra PC2-5300 memory from Golden Emperor International LTD. This memory ran respectively at DDR2-667MHz and it had maxed out at DDR2-843MHz speeds. Since then GeIL has released a new set of memory modules -- GeIL Value PC2-8000 DDR2 Dual Channel Kit. Today we have the modules that are rated to run at 1.0GHz and are designed to break the performance barrier with Intel 955X Chipsets. We have cradled the GeIL DDR2-1000MHz modules inside of an Abit AW8-MAX v1.0 and are taking these modules for the ride of their life.
