hp pavilion (intel) ecc ram on non-ecc mobo?

[wwdwgs]

Hello, everyone,
I'm thinking about upgrading hp pavilion m9040n (momo IPIBL-LA) as follows:

existing cpu core 2 quad Q6600 (socket 775) to replace with Xeon x3320 (or x3380)
existing graphic card (broken/unknown) to replace with ATi or Nvidia 1Gb (various models)
and, maybe, existing non-ecc unbuffered ram to unbuffered ECC ram (Server type).

Xeon chips suport ecc ram (buffered? unbuffered?)

problem - will the unbuffered ECC ram work on mobo that spec'd to run non-ecc unbuffered ram?

The reason I'm thinking about replacing ram (especially) is to have reliable memory and, therefore, overall reliable system without programs freezing, lagging, or computer shutting down.

I intend to run either winXP or win7 (64-bit) and autocad 2008 or 2014 (respectively).

ECC ram are necessary for data center's or at least for programs that crunch through data on a large scale. Chances are you'r going to achieve the same performance from non-ECC rams as well though it's entirely depending on your applications. When you're talking of Windows 7 as well AutoCAD you should be informed that they both work perfectly fine on off the shelf, mainstream consumer grade parts so you're over thinking it.

On another note, you'd be better served with buying into a new platform for running the latest apps instead of spending on an aged platform primarily because anything like an LGA775 based Xeon would be second hand and ECC rams aren't that cheap to begin with, let alone getting reliable warranty for a DDR2 module/DIMM.

I won't dig deep into the bandwidth issue but DDR2 caps out at 1066MHz where as DDR3 caps out at 3000MHz. DDR4's frequency's start off at 2133MHz. The final point worth making is that not all motherboards support both non-ECC and ECC rams and in your case it only supports non-ECC DIMM's.

IMHO, moving onto a Skylake system would net you more returns and piece of mind especially if your machine is supposed to generate income.

Based on the mobo specs, it doesn't support Xeon, it also doesn't support ECC DRAM so those are out. And I wouldn't be hoping for a BIOS update that will change any of that 😉 Prebuilts seldom get updates to improve compatibility - they want you to just buy a new PC (preferably their;s 😉 )

Agreed!
