Hi!i got a new pc:Hp compaq 6000 pro sff and i need to upgrade its cpu.Recently i found on ebay some E5440 which are modded and work straightforward in lga 775 cpu no need for stickers.My question is:would it be able to run on my mobo?Q43 chipset but it supports q9550 and q9650.
 
Since no one else has answered, I'll take a crack at it. You'll have to track down the CPU support list for the particular motherboard in your machine. It's highly doubtful that chip is listed, since it's technically for a different socket. On most enthusiast motherboards, the BIOS supports a wide range of chips and the manufacturers often even update to include cases like this. Unfortunately, for a typical OEM prebuilt system, far less likely that the manufacturer would bother to insert support. So it's going to be a crapshoot. If the new chip is cheap enough, try it and see, but I wouldn't hold my breath.

As an alternative, there are a ton of much, much faster used systems on eBay or similar for really good prices. Might consider a full upgrade instead of just a new chip.
 
well in the hp page for my current pc it says it supports core 2 quad up to q9560.i found in a forum that if it can handle q9560 it can handle e5440 but the q43 chipset is not compatible?

Can you post a picture of this modified processor?

The reason I am asking is because it takes more than a sticker to use a LGA 771 Xeon in a LGA 775 socket. It also requires the two circled pieces of plastic in the LGA 775 socket be cut away:

yup the price is between 19-22$ for e5440.however for x3353 its 20$ cpu and 2$ for 10 stickers

I've personally given up on this 771 mod. Tried e5420 on a g33 mobo (listed as supported). It needs a microcode update to even boot windows (it freezes otherwise). Once i got the cpu started, it's simply not stable, not even on stock speeds (usually one core fails). Tested with prime95


Touching any overclock settings kills stability even faster or even reboots the machine while it's booting.

So i either got a dud of a cpu or this isn't as straightforward as popping a good ol' 775 quad in.

hojnikb, what G33 board are you using?

I'm using gigabyte g33m-s2 with F6 bios and 2010 microcode.

Yesterday reflashed the board, resetted the bios, removed all but 1 2GB ram stick and set the memory:fsb ratio to 1:1, disabled virtualization (had issues with this in the past on some cpus). It survived 12h of prime95 and is still running (can't check cous work 😀 ).
If this indeed ends up stable after 24h, it may just be some weird ram/bios settings incompatibility.
