1066 FSB CPU with 800MHz PM965

[RickAbraham]

I was talking with a bloke from a local PC repair shop and I watched him fit a T9600 processor into a Dell laptop running the PM965 Santa Rosa platform which is only 800MHz.
The processor was fully compatiable which shocked me and I watched the machine boot up after the installation was complete.
But what I want to know is are you going to get the full gain using a 1066 FSB when the chipset apparently doesnt support it.
I have read on other forums that the PM965 refresh chipset is a freak some claim that it will support 8gb of ram and others claim 6gb of ram.
Would the mobo downclock the CPU to 800 FSB or has anyone tested this upgrade and can prove that the chipset will run at 1066MHz ??
I am interested to find out.

I don't think anyone here knows, otherwise people would be doing CPU pin mods to overclock their CPUs to a 1066mhz fsb.

It may provide some interesting info to you.

Maybe the OP made a mistake, and the CPU was T7600?

I'd be rather surprised if T9600 would even work in 965 PM.

There was a discussion about this a couple months ago. The pin outs are different, that's why you can't use a X9000 in a PM45 system.

What about the other way a round?

Second gen penyrn in 965 pm? either the OP must have saw it, or he saw something else...

Pics or vid? Else not possible from various tests users on this forum have conducted.

So what you guys are saying that the T9600 pinouts are different and that it cannot be used with a PM965 chipset ?
Im sure he said it was a T9600 he fitted but I could be wrong I might ring him and double check.
