Hey kwarkers, I also am an Asus A8V-E Deluxe owner, and I'll share what I know.
I have an Athlon64 3700+ (2.2Ghz stock) overclocked to 2.8Ghz (255 x 11). The board, as noted in other reviews, will not boot past 266, thus somewhat limiting overclocking. Since I OC for CPU speed and not bus speed, such a limitation is minor. I use use 2 sticks of Corsair XMS 512's, and use the memory 166 divider (DDR333) to run them at DDR400 speeds with OC. (255 x 11 = 2805; 2805/14 = 200.35 or DDR400). To keep the processor stable, I raised the Vcore (wierdly named Hammer Vid control in the BIOS) to the max 1.5625v setting. Note I use the 1008 BIOS update from ASUS. I have also replaced the stupid chipset fan with a Zalman passive unit which is amply cooled by my Thermalright XP-120 with a 86cfm Panaflo fan. I also keep the LTD bus frequency at 1 Ghz. My memory is TCCD based thus is happy at the 2.75v stock voltage with 2-2-2-7 timings at 1T. As a side note, I have two 74Gb Raptors running RAID 0 off the motherboard. My setup runs Prime95 without a hitch as well as MEMTEST86, so good luck with your setup. I have all this installed in a Lian-Li PC-60A Plus powered by a Antec Truepower II 550.

In addition to the above, I remembered that with setting the Hammer Vid control to 1.5625, you also need to set the CPU Vcore offset to +200mv. This, strangely enough, raises the voltage to past 1.6v. The ASUS AIBooster shows my board to fluctuate between 1.63v and 1.66v. The reason I mention this is because Prime95 will fail at 2.8Ghz with the CPU Vcore offset at +100mv. Anyway, I recently ran an 8-hour stint of Prime95 with no problem. Having the CPU voltage this high makes it run hotter, as Prime95 torture test blend load raised my temp to 51C (Under normal loads, I rarely pass 46C and idle at 32C).

Just remember that this is for a San Diego core, however your Venice chip is similiar and should be able to post near what I have observed for this board. Good luck.
