Cool [review] Ultra High Performance Ram comparison AMD64 s939 @ madshrimps.be

http://www.madshrimps.be/?action=getarticle&articID=277

System:

AMD Athlon FX55 S939
MSI K8N Neo2 Platinum
EVga Geforce 6800 Ultra
Modified Prometeia Mach1 R402a by Chilly1


compared:

# Centon PC3200-C2x512PC3200LL
# Corsair TwinX 1024 PC4400C25
# Geil Ultra X-GLX1GB3200DC
# G.Skill PC3200/PC4400 1024-LE
# G.Skill PC3200/PC4400 1024-LD
# Mushkin PC3200 Level II V2
# OCZ PC3200EL Rev2
# PDP PC3200-PDC1G3200+XBLK
# PQI PC3200-PQI3200-1024DPU (2.6v)

Testing/ Methodology :

Testing was initiated by running OCZ Memtest86+ to determine max stable/passable memory frequency. Voltages were varied in an effort to find best combination of voltage for each set. Once maximum frequency was determined, full benchmarking was completed, or attempts at completing were undertaken. With most sets tested, there was often instability in attempting to complete all benchmarks listed at what passed without error in OCZ Memtest86+.

Memory/HTT frequency was then lowered incrementally until all benchmarks could be passed in succession. Any hints of instability and frequency was again lowered until I was comfortable with results and that the ram was indeed stable at this level, as much as I can be without a hardware memory analyzer.

Please note, an 80mm fan was installed aimed at the modules as they got very hot during testing and in the past I have noticed improvements of up to 10MHz or more in the ability to clock memory higher.

CPU speed was unable to be stratified across different speeds for each set, therefore we choose to use an 11X multiplier through all testing. Please keep in mind that increased performance seen at higher frequencies is in part due to higher CPU speeds which ranged from 2750MHz through 3080MHz.

OCZ memtest, interesting.
Testing of this magnitude must have taken ages
