HP 550 CPU upgrade

[GramaFon]

Hi 
I have HP 550 with gme965 chipset

want to upgrade the CPU  ..

Now on it I have Core 2Duo   T5270  with FSb 800

if I put on it a CPU with FSB speed of 1066 .. Will it work ?

I know that enyway it will pass maximum of 800 mhz .. but not matter ..will it work or not ..

Want to change with Core2duo T 9600 or T9800

Thanks for reply I have actually found a person on internet  who did try it ..and it didnt work ..so that I have bought the T9500 because of its 800 speed ..and also find in intels page that GME965 chipset support them ..

My guess would be no....just from the read... but unless we get your System P/N to verify the highest processor it can be upgraded to. But from my experience 1066 is reserved for higher end boards and 800 and 1066 board CPU don't cross or work in each configuration.

How Do I Find My Product Number?

HP only offered three processors on that model:

● T5670 1.80-GHz processor, 2-MB L2 cache, 800-MHz front side bus (FSB) 

● T5470 1.60-GHz processor, 2-MB L2 cache, 800-MHz front side bus (FSB) 

● T5270 1.40-GHz processor, 2-MB L2 cache, 800-MHz FSB

The logic seems compelling. Other processors with the same socket, same fsb and known compatible with the chipset will work, right? Ain't necessarily so. In fact, odds are against it. The only processors which can be guaranteed to work are the ones listed above. Others might but unless someone here has actually tried it (unlikely) we don't know. If you try it and it does work please let us know as that adds to the knowledge of the Forum.
