Gigabyte GA-P35T-DQ6: DDR3 comes a knocking, again

QX6700 Quad Core Overclocking
Needless to say, quad core overclocking on the P35 platforms has been an unknown to some extent due to the limited availability of boards. Our board reached a final 365FSB that we found to be extremely stable during testing and exceeded the 361FSB we have reached on the ASUS DDR3 board. Of note is that our processor will actually do 3920MHz but we had to run slightly higher voltages on this board and reached the limits of air-cooling at 3650MHz. Our memory timings had to be relaxed slightly with CAS being set to 9 and voltages increased to 1.60V for 2GB and 1.70V for 4GB configuration.
We dropped the multiplier on our QX6700 to eight and were rewarded with a final 8x457FSB setting that was limited to air-cooling. However, even with some quick test runs with water cooling we found our final FSB would not exceed 470MHz due to problems with our memory running stable once we neared the 1600MHz mark with it. Gigabyte is currently working on this problem and we hope to have an update shortly. We see the 8x457 setting offering the best write and copy scores with read and latency performance just trailing the 10x365 settings. In preliminary testing, our 8x457 setting generally scored about 1% better in most of our application and game benchmarks. We will have overclocked scores in our roundup article.

[With apologies to Monty Python, I present the Quest for the Holy Chipset....]------------------
"One day, lad, all this will be yours!"
"What, the heatsinks?"
"No. Not the heatsink, lad. All that you can see, stretched out over the caps and resistors of this land! This'll be your motherboard, lad."
"B-- b-- but Father, I don't want any of that."
"Listen 'Erbert. We live in a bloody planet full of global warming. We need all the heatsinks we can get."
"But-- but I don't like her."
"Don't like her?! What's wrong with her?! She's beautiful. She's rich. She's got huge... tracts o' land!"

wtf is wrong with intel boards lately??I mean, in every article I read, it doesn't matter how HUGE the heatsink is, "additional airflow was required to ensure stability". Or do you mean just a casefan?
I still have a dfi nforce4 ultra board, replaced the (tiny!) chipset cooler with a thermaltake hr something, and the chipset temp dropped 10°C, htt goes wel over 300. Huge difference there.
