Does X58 support ECC Registered Dimms?

[Aggravated Salmon]

I was having the typical x58 disappearing RAM problem and no matter how I configured the RAM/ adjust QPI/DRAM voltage/ change timings, my motherboard can still only detect 8GB RAM when I have 24 GB installed in all 6 RAM slots. So I decided that I’ll just buy large DIMMS, as I know which slot my motherboard is so called using the RAM from. However 16GB Dimms are expensive unless they are Registered ECC RAM. I found a lot of conflicting information online so I just want like a straight answer. By right the memory controller is on the CPU not the Northbridge or Southbrige so I should be fine as I am using a Xeon X5660 but some say only ECC unbuffered works, yet some say registered ECC RAM works on x58 and x99 but not x79.

 

For the record, my BIOS has the option to turn ECC mode on or off so I know it supports ECC.

i don’t need the ECC function I just am trying to save money as I have a local listing of 80GB R-DIMMS for $75.

 

specs:

Intel Xeon X5660 (4.4Ghz @ 1.4v)

240mm AIO

ASUS ROG Rampage III Formula

Cooler Master Silent Pro Gold 1200W

no way, I tried couple bios, i7 and couple xeons, no way of using registered ecc, non-registered ecc might work on x58 chipset, for reg ecc you need server board

non-ECC RAM only. You'll need to switch to an i5520 server chipset.

Ye another guy with an MSI board told me the same. But since my ASUS board has the ECC function, I may stand a chance. Just hope someone with a similar ASUS board sees this. Thanks anyways!!!

unbuffered ecc has a chance to run on x58, not nativly but still, but reg is another thign

My BIOS has an ECC toggle function so I know it accepts ECC (as long as I use a Xeon cos memory controller on CPU)

unbuffered ECC is more expensive than non-ECC so it's rather pointless anyhow.
