Re: looking for DDR3 1333MHz ECC memory

[Derek Trotter]

About 15 years ago a friend of mine fried a motherboard and the new 
memory he bought for it.  He told me he put the memory in backwards.  I 
never understood how he managed that.  The notch in the simm wasn't in 
the center.  It could only fit one way.

Re: looking for DDR3 1333MHz ECC memory

[Steven A. DuChene]

Definitely not a SuperZMicro board. It is a prototype Intel motherboard. The MB 
has a Intel logo printed right on it. I had shown this board & CPU at a PLUG 
developers meeting at the technical college on Baseline a few months ago. The 
motherboard has some very unusual construction features.

It cannot be a Clarkdale or Arrandale core since the motherboard definitely has 
three memory channels and the Clarkdale or Arrandale cores are only dual 
channel. According to the tables shown on that same Wikipedia page, with the 
tripple memory channels, it has to be either a Bloomfield (single socket - 
tripple channel) or a Gulftown (single socket - triple channel).  If it is the 
Bloomfield then it takes DDR3 1066MHz memory rather than the DDR3 1333MHz 
possible for the later Gulftown cores (the early Gulftown cores still use DDR3 
1066MHz memory as well).

So perhaps I need DDR3 1066MHz memory rather than the 1333MHz stuff.

It looks like you just have the wrong:

slots populated 
or
memory for your chipset/mobo:


>From Wikipedia:
Nehalem microarchitecture based

Main article: Nehalem (microarchitecture)
With the release of the Nehalem microarchitecture in November 2008,[14]
 Intel introduced a new naming scheme for its Core processors. There are
 three variants, Core i3, Core i5, and Core i7, but the names no longer 
correspond to specific technical features like the number of cores. 
Instead, the brand is now divided from low-level (i3), through mid-range
 (i5) to high-end performance (i7),[15] which correspond to three to five stars 
in Intel's Intel Processor Rating[16] as opposed to the entry-level Celeron 
(one star) and Pentium (two stars) processors.[17] Common features of all 
Nehalem based processors include an integrated DDR3 memory controller as well 
as QuickPath Interconnect or PCI Express and Direct Media Interface on the 
processor replacing the aging quad-pumped Front Side Bus
 used in all earlier Core processors. Also, all these processors have 
256 KB L2 cache per core, plus up to 12 MB shared level 3 cache. Because
 of the new I/O interconnect, chipsets and mainboards from previous 
generations can no longer be used with Nehalem based processors.
 Core i3
The Core i3 was intended to be the new low end of the performance processor 
line from Intel, following the retirement of the Core 2 brand.[18][19]

The first Core i3 processors were launched on January 7, 2010.[20]
The first Nehalem based Core i3 was Clarkdale-based, with an integrated GPU and 
two cores.[21] The same processor is also available as Core i5 and Pentium, 
with slightly different configurations.

The Core i3-3xxM processors are based on Arrandale,
 the mobile version of the Clarkdale desktop processor. They are similar
 to the Core i5-4xx series but running at lower clock speeds and without
 Turbo Boost.[22] According to an Intel FAQ they do not support Error 
Correction Code (ECC) memory.[23]
 According to motherboard manufacturer Supermicro, if a Core i3 
processor is used with a server chipset platform such as Intel 
3400/3420/3450, the CPU will support ECC with UDIMM.[24]
 When asked, Intel confirmed that, although the Intel 5 series chipset 
supports non-ECC memory only with the Core i5 or i3 processors, using 
those processors on a motherboard with 3400 series chipsets it will 
support the ECC function of ECC memory.[25]
 A limited number of motherboards by other companies also support ECC 
with Intel Core iX processors; the Asus P8B WS is an example, but it 
does not support ECC memory under Windows non-server operating systems.[26]You 
HAVE to have some information on that mobo?  It should be a Supermicro.  


As far as I can tell, your non-ecc is the correct memory.  
Is the partity right?

Check the docs before you screw around with ECC.

No video is usually preceeded/accompanied with a bios memory test error, do you 
have memory test errors enabled in the bios?  Is there beeping?

[Dazed_75]

If you get ddr2 memory into a ddr3 slot, you already broke it.  It will not
fit due to the slot placement.

looking for DDR3 1333MHz ECC memory

[Steven A. DuChene]

I have a mystery motherboard with what I believe is a Intel Nehalem server cpu.
I think the type of memory I need is PC3-10600 DDR3 1333MHz ECC memory.
The board seems to have a A, B, and C memory channel from what I can see on the 
motherboard.
I believe I can either put two identical DIMMs in with one in channel A slot 0 
and the other in channel B slot 0 or I can I think I can put three identical 
DIMMs in slot 0 of all three channels.

I have tried PC3-10600 DDR3 Non-ECC DIMMs but I did not get any video,

Before I go out and purchase some new memory does anyone have any spare 
PC3-10600 ECC memory DIMMs they could bring to a PLUG meeting so I can try to 
see if that is the correct memory before I purchase new DIMMs?
