No benchmarks, simply Memtest stability testing.
4 PSC dual-channel kits, aircooled with a 8cm 1900rpm fan, CPU also air-cooled. Shame that the real fun with these chips starts under cold

TestMemtest for Windows 100% coverage stability under
24/7 user sweet-spot timings of 6-8-6 ( ideal for maybe Clarkdale ) and 6-9-6
using stock voltage ( 1.64 Vdimm BIOS , 1,657 V DMM measured )
ConsiderationThis is only a rough round-up. OC for varies from kit to kit up to +-30 (60 DDR) MHz.
Motherboard over- or undervoltage. During testing usually, 0,2V voltage bump resulted in 10-15MHz (20-30 DDR) MHz stability-limit-raise
These are all retail kits, no samples or ES.
Prices inticated are just for relative comparison.
