After letting memtest86 run for a while, I started digging around to see what I can push the system to. I am taking the safe route by going low voltage. I wanted to get the highest overclock with the greatest stability.
I pushed my 2.13Ghz Core 2 Duo up to a FSB of 345 from the standard 266. This raised the processor up to 2.76Ghz. I am confident I can get it faster with some more tweaking.

The ram was moved all of the way to the effective 1038 bus speed.
BIOS changes that I have done are: (Bios Version: 12/01/2006)
- C1E Function - Disabled
- PPM Function - Disabled
- CPU Clock setting - 345
- PCIE Clock setting - 101
- CPU VID offset setting - 25.0 mV
- CPU VTT Voltage setting - 1.30V
- DRAM Voltage Setting - 2.30V
- NB Chip Voltage Setting - 1.70V
Now with the basics of what I have done have been laid out, I started with PCMark05 on my list of test to do.


Memory has gone up a total of 1497 point in the benchmarks compared to other slower modules.
I also went through all of the other FutureMark and AuqaMark tests.

After all of the above test and even a round of Super Pi (32M) I was still able to run Orthos by Johnny Lee to get prime95 working on all processors for 8 hours, It is just not considered stable until you can do all of the above.

With everything stable, I am able to move over to the memory bandwidth.

With the ram rated as fast as it is, it is hard to get a motherboard that is rated to handle the DDR2 PC2 1200 RAM. Right now I know of a couple of boards that supports the 1200mhz, with more coming out all of the time. The DFI Infinity 975X/G looks to me as if the limit is right around the 1050 mark as I go higher it is harder to keep things stable.
The KHX9600D2K2/2G kit has been a fun kit to play around with since I have had them. I am sure in the future I will have to do an update as I get a new system to test on with the better RAM bus speeds, but right now I have to say this kit is rocking my E6400 for speed and keeping the ram setting at 800Mhz. A lot of the other companies heat spreaders for their ram are getting away from the standard look. Kingston has kept theirs the same with no ill effects.
I did have issues with the first kit they sent, but this was fixed when they shipped out a second kit. It has been rock solid ever since.
Thanks to Kingston for sending out this sample!
