Q9550 on stock voltage?

Picked up my new Q9550 from a local store here in Canada (pack date 7-9-2008, L815B315). When I installed it on my cheapo Asus P35 P5K-E, using the latest Coretemp it shows the VID as 1.1750. After some testing at stock voltage and some break-in time, I set the VID voltage in my BIOS I am currently running at 3.6 Ghz (well actually 421 X 8.5) rock stable (6 hour prime) with my 4GB of DDR2 at just somewhere over 1000Mhz. I have load line calib enabled, FSB Termination V at 1.2 and CPU PLL V at 1.5 and everything else on auto except for my RAM which I manually set it at its rated speed of 5-5-5-12 1000Mhz 2.05V.

Is that my stock voltage or is that the MAX voltage recommended for this chip? Am I going to blow this thing up? I figure 3.6 is way better than how hard it was before to get more than 3.2 or so from my Q6600 without giving it some serious juice and having the temps go soaring but that Q6600 is a workhorse and has never let me down and I still use it for work in my eVGA 680i.

Realtemp shows idle temps after about 15 min of me surfing, music and doing little on it at around 31,30,30,33 using my old and trusty Tunic Tower in a P182 case using my PC P&C 750.

My friends and the lad at the store told me I was SOL in regards to the cheap P35 board I have at home and I would be lucky to get much over 3 Ghz. I was told I needed to get a X48 chipset or X38 at the very least and if I was really lucky maybe a P45. This Asus P5KE has treated me very well and I don?t want to dump it, considering I only paid like $115 Cad for it and just $85 for the 4 GIGs of my DDR2 RAM after rebate.

Was my P35 board made for these new 45nm cpu?s? Will I get errors down the road or will I fry the chip or the board or video card etc, like the guy at the store is telling me or he is just trying to get me to buy a new board? Sorry these 45nm new cpus are totally new to me and so are the new chipsets (all I know are P35 and nvidia ones and older AMD ones) and I have no idea other than I needed a new Quad and the 9550 dropped by like $250 here so it was a no brainer.

I'm planning to get a Q9550 for my P5K-E later.. Yes the P5K-E officially supports the 45nm ones. I plan to flash my BIOS to a newer version before I install the Q9550 because my current BIOS from 2007 doesn't officially support it.
It should be a relatively good P35 mobo.

About the voltage: Intel likes to keep the vcore between 0.85V ? 1.3625V. You can check what your vcore is by using CPU-Z and looking from it. I don't know anything about FSB termination V or CPU PLL V values, so dunno if anything there will blow anything up.
