In most legislations, updating DRAM or CPU is a typical user right, not breaking the warranty. Obvious, you need to swap back to the original set-up in case.

Using which technology, command set, ...?
frustin wrote:- The i3 3220 has the AVM instruction set, which improves Linux raid format (assuming that QNAP use it in their kernel build) which QNAP would probably want to make use of.
Guess you talk about the AVX instruction set extension. Yes, there was some code added to speed-up some operations.
The additional code related to RAID6 was added and committed to the Linux RAID in December 2012:
lib/raid6: Add AVX2 optimized gen_syndrome functions
Add AVX2 optimized gen_syndrom functions, which is simply based on
sse2.c written by hpa.

There was no such beast on the similar models with CPU on higher heat dissipation.
frustin wrote:- Memory types are different DDR3-1066 for the celery and DDR3-1333/1600 for i3 - this will impact performance, motherboard compatibility(?) and cost
Questionable if this makes an advantage or the NAS functionality - which is limited by other factors. Faster DRAM is more mainstream, prices are lower interestingly.
frustin wrote:- Obviously this is not a reason for choosing i3: Cost is nearly 3x more for i3.
Obvious - the price of the non-pro must be lower therefore. Looks like QNAP does se Europe and North America to be "price sensitive". For my part, I don't fully agree - as this class of NAS has some geek factor. Thus I'm concerned about the Celeron decision.y
