I've started looking into what it will take to upgrade the processor in the HP EX470/475. The stock processor is the AMD Sempron 3400+, but AMD makes several voltage configurations (see this comparison chart from AMD's web site). I haven't verified if the 3600+ or 3800+ will work in the EX470 yet.
[update... I have visually verified that the processor in the EX470 is in fact the AMD part # SDD3400IAA3CN. It is likely that a Sempron 3500+ will work (see this comparison chart) and while you gain 200 MHz in speed, you loose 128MB in L2 cache. The Athlon 64 X2 Dual Core has a different voltage listed. The Athlon 64 3500+ looks like a winner. The 3600+ and 3800+ (mentioned above) will NOT work as they are not 35W parts.]
Below is a screen showing the output from CPU-Z. It shows an AM2 (940) socket.
I'll keep you posted as to my findings.
*** UPDATE ***
It has been pointed out that the Core Speed in the above screen shot is too low (it should be 1800 MHz not 1000 MHz). It appears that the AMD CPU has a mode called "Cool n Quiet" that reduces the core speed during periods of low CPU utilization.
I've taken another screen shot during a file search:

Mission accomplished! Read about how you can get a 40% increase in processor speed for around $50. A detailed step-by-step guide can be found here.

Based upon your findings, would a AMD Athlon 64 3500+ Orleans 2.2GHz 512KB L2 Cache Socket AM2 62W Single-Core Processor
work as a good upgrade?
Any update?
The purpose of this puppy is to run long and do file sharring only, right? wouldn't the existing processor with "save energy" mode make more sense for this application? IMHO, if one needs a screamer server,a custom build with installed OEM version of WHS should be an option.
I haven't taken apart the EX470 as of yet. Two questions..
- who is the manufacturer of the motherboard?
- is AMD making a new 35W Sempron processors...or is that the end of the line?
It appears there are two different versions of the AMD Athlon 64 3500+.
ADD3500CNBOX - which has the 35W rating
ADA3500CWBOX - which has a 62W rating
Everything else seems to be exactly the same for these two version. Funny thing is that most of the processors left available seem to be the ADA version and not the ADD version.
So any update? Has anyone tried this?
Well- Looks like i will put my toe in the water..
for around 50 bucks i can pick up a AMD LE-1640 Orleans 2.6GHz 1MB L2 Cache Socket AM2 45W Single-Core from newegg-
I found on another site (wegotserved.co.uk) someone that had upgraded - I figure to go from 1.8 to 2.6 is worth it- however i am worried that the OS just might say- umm your now not legit- I will let you guys know if this works and will document my steps for you all- just like the $40 upgrade to 2gb or ram. a $50 upgrade for the processor will be worthy. Please let me know if anyone has anything to add.
I Did it! it took all of 15 min to accomplish however it has been done.
I have added a AMD LE-1640 Orleans 2.6GHz 1MB L2 Cache Socket AM2 45W to replace my original 1.8 AMD chip.
NOTES:
This chip will not show up under system properties.. just an Unknown AMD
Releasing the Heat sink from the original was hard and scary. I literally pulled the whole chip and sink off the motherboard. I was lucky no pins in the original chip broke.
The new chip comes with a heat sink you cannot use. Clean the original and reuse it. i had to use a screw driver to get the chip off.. just a little twist to pop it off the sink.
Tempiture. my HP WHS box was normaly 21 degrees celsius. The new chip will sometimes go up to 31- 32. but it alwasys comes back down to 21-19.
Make sure you purchase 45W version in order to help keep the chip cool and the energy level of your system the same.
Improved Performance? Well yes!
Thanks guys-
Oh BTW theAMD LE-1640 Orleans 2.6GHz 1MB L2 Cache Socket AM2 45W as you can see has a 1MB cache!!!
What about using the AMD Athlon X2 BE-2350 Brisbane 2.1GHz Socket AM2 45W Dual-Core Processor ?
I have also installed the AMD LE-1640 Orleans 2.6GHz 1MB L2 Cache Socket AM2 45W and the G.SKILL 2GB 240-Pin DDR2 SDRAM DDR2 667 (PC2 5300). Both with no issues at all. On the HP EX475
I just picked up a BE-2300 today to try if it works I will be replacing it with a BE-2400 just to get a little more.
I learned a lot from this post...Enjoy!

I have my own "how to" complete with detailed instructions and LOTS of pictures coming soon!

dose any body know where i can get the 2.6 ghz processor? or if one of the 45w amd 65nm processors will work with the ex 470
