Fremont, California, USA, February 21, 2008 - Patriot Memory, a global provider of premium quality memory module and flash memory solutions, today announced the release of their DDR2 Extreme Performance, 4GB Viper Series PC2-8500 (2 x 2GB) enhanced latency kit.

EPP eliminates the need for any manual configuration, allowing uncomplicated overclocking capabilities for consumers looking to maximize the performance of their systems.

with 2GBX4 4GB kits, viper passed ddr2-1200c5 in dual super pi 32m, kind of stable for sure
and the vdimm only 2.0v, look at the hardware mointor,the VIN1 is the mermoy voltage, aslo we set
+2.0v in X48 DQ6 bios.

-----------------------------------------------------------

update this after few hours, paid more attentions on this pair
all like what i mentioned , large capacicy & high speed are very depended on
MCH & bios tweaks from Gigabyte.

discover what the lowest voltage i could run 1066mhz with 4GB kit
we know the official release viper 1066 and 2.3v
though can't set direct voltage what i want in bios
if leave "normal", will let motherboard auto set to 2.2v
so i need to set it manually, +0.5v in bios, and the real is 1.87v
that what i can set the lowest voltage with X48 DQ6.

im very impressived with the ultra low voltage, i get 1.87v and 1066c5
at this frequency, still very stable.

1.87v 4GB(2GBX2) viper DDR2-1066mhz CL5.

so i keep go on, tried 1100,1120.....and finally i were shocked by this pair
with the very low voltage 1.87v ran dual super pi 32m and pass 590mhz (affective DDR2-1180)

1.87v 4GB(2GBX2) viper DDR2-1180mhz CL5.
