Today I started overclocking for the Gigabyte Beat me if you dare competition.
This morning I started with stock air benching in 3D Mark Vantage. to my surprise with stock cooling and stock Voltages I achieved a max stable core clock of 775MHz, 1300MHz Memory, and a Shader clock of 1710MHz.
This is rather impress considering the stock core clock for the SOC card is 680MHz vs the reference clock of 576MHz. Nearly 200MHz of overclocking headroom!!!!
My impressions this far lead me to believe Gigabyte has a card worthy of the Overclock name! (Move over ASUS TOP?)

3DMark Vantage Single GTX 260:
Performance 13773 3D Marks
Resident Evil 5 game benchmark: N/A
fps score: 116.6
Screenshot:
CPU: Intel i7 Xeon @ 3200MHz
Motherboard: EVGA CLASSIFIED 759
RAM: 6GB of Patriot Viper 1600MHz DDR3 Triple Channel @ 1866MHz
GPU: Gigabyte GTX 260 SOC (216 SPP) @ 775MHz Core, 1300MHz Memory, 1710MHz Shader clock

Here is the naked PCB with cooling assembly removed
Next I apply heat sinks to the two secondary thermal zones
Kneaded eraser is used to prevent condensation or buildup of ice on the PCB
I have also coated the back of the card and used RAMsinks on the rear MOSFETS
Next I mount the Liquid Nitrogen Evaporator
benching the card with CPU on air

Time for some LN2 Action!
3DMark Vantage Performance Benchmark 15244 3D Marks
Intel i7 Xeon @ 4933Mhz -75c
Gigabyte GTX 260 SOC @ 840MHz Core Memory 1300MHz Shader 1853MHz -120c
Patriot Memory Viper DDR3 3x2GB 1600MHz @ 1969MHz CR @ 1T
Resident Evil 5 Performance Benchmark 142.1 FPS Average
With a max stable core clock of 840MHz at -120c The only thing holding me back are these stock voltages!
I have a Vmod in the works for the GPU Core and will be posting some EXTREME GTX 260 Benchmarks.
Big Thanks to Zuriah, my LN2 helper
