I'm sorry, are you saying you can or CANT use a Intel 2400, 2500, 2500k, 2600, or 2500k on a server board?
CrashControl... Did you every figure it out?
I'm about to buy a brand new shiny XEON E3 1230 V2 and a board that wont boot unless I update the BIOS. I need to know if I can drop my 2500k in it to flash the BIOS!!!
It sounds like, Rainman, that you are saying the board will boot because the PCH in on the board itself and not dependent on the CPU? Can someone please confirm?
Because memory controller is integrated into CPU, support for ECC depends solely of CPU support. All 2nd Gen desktop CPUs, even a $1000 i7 3960X, don't support ECC, no matter to which mainboard you plug them; signal lines for ECC are present in socket but grounded.
I have heard reports of people booting but have never heard a confirmation. If what you say is true then why do these motherboards claim support for the i3's? Did Intel not cut the ECC on i3's but they did on i5's and i7's? A source would be nice as well. Rainman linked to a document that said ECC was solely dependent on the PCH.
I just ordered the Supermicro c204 based server motherboard and ECC ram from the egg. I will drop my 2500k in the system and test for myself before deciding which processor to buy for my server. This will allow me to update the BIOS for the E3 1200 series V2 (the CPU I plan to purchase) if it works.
The lack of info is utter crap. Intel should say things like, "May work but is unsupported, not recommended". They should also state whether they cut features on purpose... Bureaucratic company I guess.
I found some details on Wikipedia that say the "support" of ECC on the i3's may carry over to the i5 and i7's. I will post my findings here when the equipment arrives.
Intel statement is that i3 family not support ECC memory - Intel� Core� i3 Desktop Processor — Frequently asked questions . May be Intel have special models for entry servers with ECC support - but unlikely you can buy them in usual computer store.
Here is someone selling a server with an i3 and ECC RAM.
...And here is the motherboard that I just purchased
Single socket H2 (LGA 1155) supports Intel® Xeon® E3-1200 & v2 series, 2nd Gen Core i3 processors
So the Sandy Bridge i3 obviously works even though Intel says it doesn't. What about the i5 and i7? We are obviously talking about unofficially here. Has anyone tried it?
