LGA-775 & P45t: highest memory speeds

Before I fried my gigabyte ep45t-ud3lr, I had been planning on trying to work on my memory overclock. It supported really fast DDR3 memory bus speeds (all the way to 2200Mhz), but the most I ever got out of it was 1348 Mhz.

Did anyone out there ever get the memory bus on a DDR3 P45t LGA775 platform to any significant speeds?

I decided to fire up my old P45T combo... It seems that quite a few of fsb latch and memory divider/multi don't really want to cooperate (boot) at higher ddr3 speeds?

I did manage to get ddr3-1600.

I'll probably continue to play around some more... I'm surpised to see this old Kentsfield running @480 fsb.

MCH Latch:400... System Memory Multi: 3.33D... Dram: 1.5v

MCH Latch: 333... Sytem Memory Multi: 4.00B... Dram: 1.6v

The Gigabyte Ep45t Extreme, one of the best LGA775 'boards ever made. In retrospect, I wish I had spent a few more $$$ and bought one of those instead of the Ud3lr.

At 500Mhz+ I couldn't get my ud3lr to boot at anything greater than a 2.66 memory multiplier.

I ran dual cores... E8400/E8600 along with P45 DDR2 boards back in the day. I had a nice Gigabyte EP45-UD3P (rev.1.0) which I ended up trading for my first quad core cpu (i5-750). Later when I was still running an X58/i7 combo... This board was put up f/s in OCF Classifieds and I thought it would be interesting to revisit C2-Duo/Quad again with DDR3.

I was playing around some more and I was able to boot the QX6850 into windows at 500 fsb with the 400 latch/3.33D multi... The settings weren't really that stable and I've gone back to "crunching" at 3.33Ghz with all stock/default voltage settings. I may at some point drop in my E8600 and try pushing 500+ fsb...
