Intel due to the Core 2 Duo processor launched,
Already heat up and shinning for half year.


But since the Intel platform chipset only have few products to use,
Even the overclock performance is great, but they are all Intel chipset based.
Let us feel not enough competitors with price competition in the market.

NVIDIA launched 680i/650i in end of last year, and ATI RD600 this year,
They did input some vigor into the market, also start another chipset and
market competition.

NVIDIA 680i FSB overclock ability maybe behind Intel P965 series,
But they did support SLI technology, EPP DRAM overclock and 3 more PCI-E X
16 slot for great new spec.
Another important point is memory overclock ability and divide rate is better
then 965 series.

Let's take a look on motherboard shapes.
NVIDIA nForce 680i SLI reference board by NVIDIA,
With full spec, great overclock ability, it's really a complete design.
Many motherboard makers use this directly to sell as OEM business, this
board is hot on the top segment market.




Test platform setup
CPU:INTEL Core 2 Extreme X6800
MB: Nvidia nForce 680i SLI
DRAM:CORSAIR Dominator TWIN2X2048-8888C4DF
VGA:MSI NX8800GTS T2D320E
HD:Seagate 7200.7 160GB
POWER:Corsair HX620W Modular Power Supply
Cooler:TT Big Typhoon VX




Base on DDRII 1300 frequency.

First test module

Corsair TWIN2X2048-6400C3
Default spec: DDRII 800 CL3 4-3-9




DDRII 1300 CL5 5-5-10 2T 2.35V
Super PI 32M test result





Second test module

Mushkin Tuner XP Redline
Default spec: DDRII 1000 CL4 5-4-11




DDRII 1300 CL5 5-5-10 2T 2.50V
Supet PI 32M result





Third module

CORSAIR Dominator TWIN2X2048-8888C4DF
Default spec: DDRII 1111 CL4 4-4-12




DDRII 1300 CL5 4-4-3 2T 2.25V

Super PI 32M result





Make the frequency higher

DDRII 1320 CL5 4-3-3 2T 2.45V
Super PI 32M result




This is really a great performance with timing and frequency on Intel platform, especially the voltage is under 2.5V
That makes me fell amazing on 680i great DDRII adjust ability.
Let's try more software test to verify the DDRII 1320 stability.

DDRII 1320 CL5 4-3-3 2T 2.475V

NVIDIA nForce 680i SLI reference push the MicornD9 modules to another sky
high level,
On Intel platform, DDRII 1300 is no more dream as long as the modules is
strong.
ATI RD600 chipset products also have better memory divide rate and
excellent on memory extreme frequency.
Compare ATI chipset product for Intel platform, we can see different positive
points on RD600/680i products. 

nice 3 pair of 1Khz RAM there.. nic result... but 680i still lot bios bug right?

Maybe...

2 SP2004 is acceptable.
