Default 4th of July Benching OCA style @ NexGen
4th of July weekend Hondacity and I benched the new GTX 480 on Liquid Nitrogen:

System configuration:

Motherboard: ASUS Rampage III Extreme
Processor: Intel Core i7-980x Extreme Edition 6 core 12 Thread LGA 1366 CPU
RAM: Corsair Dominator GTX4 2533MHz DDR3 Tripple Channel kit
Graphics: ASUS Nvidia GTX 480
Hard Drive: OCZ SSD SATA 2 Solid state storage drive
Power Supply: Antec 1200W TPQ


The 980X CPU was good for about 5.4GHz in 3D Benchmarks and Multi Threaded 3D CPU Tests
our Gulftown Performed better on 2D single threaded Benchmarks with about 5.9GHz max
CPU was cooled down to -196C holding -180C Full load showing no signs of a CB "Cold Bug" (After CB Mod)
The CBB "Cold Bug Boot" was -141C

A much better CPU sample is needed for record breaking, I rate this sample 6 out of 10 for LN2 overclocking


The ASUS GTX 480 was exciting to bench on LN2, we all know how hot they get on air!
The card maxed out at 1088Mhz Core with 1.25v
The onboard DDR5 managed to remain stable up to 1100MHz
The GPU had a CB of -128C and a CBB of -60c

Capacitors were added to the card for enhanced voltage stability under load. Fermi pulls a lot of current!

This GPU is only held back by the OVP "Over Voltage Protection" and the OCP "Over Current Protection"
Once the card is modified to remove these limitations Core clocks of 1300Mhz can be achieved under Liquid Nitrogen Cooling.

Man, I had a lot of fun!

I managed to break 408K in AM3 but failed to get a SS due to an error window popup

too bad we had crappy cpu's

980x would not break 5.5 in vantage or 06.......

Wprime 1024 at 5.4GHz....

OVP and OCP mod for the 480 was a total FAIL..... down one card


I am going to set up the M3E and a 655K for some 2D loving, maybe 01 and Aquamark w/ the 480


*needs to mortgage the house to start binning 980's!!!!!!
