Installed the new MB, but the Noctua cooler I ordered turned out to be a LGA775/AM2 one, so I have to return it to get the one with LGA1366 mounts.
So... this one is not with a Noctua, but with a Cooler Master Hyper 212.
Vcore of 1.33 is a bit high for 4Ghz, but I forgot to turn it down after trying 4.2Ghz.


Core i7 920 @ 4005Mhz HT:ON
Asus P6T Deluxe V2

@Warfare: High temps? Well... no guts, no glory
Its stable, and no matter what normal activities I throw at it, it stays stable @ 75-80c.
With my usage im not even remotely utilizing all four cores at the same time.

I have a regular P6T and it can accept socket 775 coolers. Is it better to use one thats designed for 1366?

I have yet to see an LGA775 cooler that fits LGA1366 without mods or separate LGA1366 mounting kit .
The mounting holes on the motherboard are further apart on LGA1366, so I cant see how thats possible.

Where have you seen such a cooler? Or statement from Asus?

skunksmash: If you like to play with benchmarks, here is some more fun with i7. Still on air (Coolermaster Hyper212, the old type)

Well, I have the board and it has 2 sets of holes for mounting coolers...
Here's a review that states the same thing..

The area around the LGA 1366 socket is really not too cramped on this version of the P6T. The 8+2 phase power design means there are fewer components in this area. Asus uses low RDS(on) MOSFETs, ferrite core chokes and solid Japanese made capacitors to make sure the power gets to the components as clean and efficiently as possible. There are a total of eight chokes around the socket with two more by the memory. One thing to notice is that Asus has included mounting holes for both LGA 775 and LGA 1366 heatsinks. This way you dont need to spend the additional money on a new heatsink, bracket or water block, something [COLOR=#289e28 !important][COLOR=#289e28 !important]users[/COLOR][/COLOR] of the popular D-Tek CPU water blocks will appreciate.

I see. Thats really a nice feature.

Asus should have done this on the rest of the P6T series, but I suppose theres reason why they havent. Probably beacause of thicker traces to cope with the increased current draw capabilities.

I doesent matter if you use a cooler for LGA1366 as long as the heat exchange capabilities are the same. The majority of coolers are designed to fit most sockets, so no one is really designed for a specific CPU.
With some exceptions of course, like coolers for servers and some of the cheaper coolers.

To stay on the topic:

Yesterday ran super-pi 1M @ 4620Mhz with my C0 i7 920, and finally managed sub 9sec. But Paint.NET crashed when I was saving the screenshot. I cant see why it would do that :P

I have the screenshot .jpg and its about the right size, but corrupt. If anyone know of a .jpg or .png repair program, let me know.

I´ll try some more when its not so warm outside. Good weather is nice, but not for overclocking.
I have a feeling the CPU has some more in it, since my RAMs not stable at 1760 7-7-7. Atleast not with 1.7v

I just played it safe with my OC

I played safe with mine too
QX9650 @ 425 mhz x 9 = 3.825 ghz
FSB: 425 x 4 = 1700 mhz
Memory @ 1066 mhz 5-5-5-12 timings

I can hit 4 ghz with a 450 fsb but just have not felt like pushing it yet.

After tinkering around, here's what I came up with as my baseline config:

3.94GHz: XMP
21 CPU Ratio
187 BCLK
DDR-1499 @ 7-7-7-22
1.29125v CPU
1.64v DRAM
Others on Auto

I can run all 4 cores @ 100% for two hours, so I'm guessing it's OK for daily use. The CPU snapshot happened on Turbo mode apparently.
