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)<
http://en.wikipedia.org/wiki/Nehalem_%28microarchitecture%29>
With the release of the *Nehalem
microarchitecture<
http://en.wikipedia.org/wiki/Nehalem_%28microarchitecture%29>
* in November 2008,[14]<
http://en.wikipedia.org/wiki/Intel_Core#cite_note-13>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]<
http://en.wikipedia.org/wiki/Intel_Core#cite_note-14>which
correspond to three to five stars in Intel's Intel Processor Rating
[16] <
http://en.wikipedia.org/wiki/Intel_Core#cite_note-15> as opposed to
the entry-level Celeron (one star) and Pentium (two stars)
processors.[17]<
http://en.wikipedia.org/wiki/Intel_Core#cite_note-16>Common
features of all Nehalem based processors include an integrated DDR3
memory controller as well as QuickPath
Interconnect<
http://en.wikipedia.org/wiki/QuickPath_Interconnect>or
PCI
Express <
http://en.wikipedia.org/wiki/PCI_Express> and Direct Media
Interface <
http://en.wikipedia.org/wiki/Direct_Media_Interface> on the
processor replacing the aging quad-pumped Front Side
Bus<
http://en.wikipedia.org/wiki/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 <
http://en.wikipedia.org/wiki/Intel>, following
the retirement of the Core 2 <
http://en.wikipedia.org/wiki/Intel_Core_2>brand.
[18] <
http://en.wikipedia.org/wiki/Intel_Core#cite_note-17>[19]<
http://en.wikipedia.org/wiki/Intel_Core#cite_note-18>
The first Core i3 processors were launched on January 7,
2010.[20]<
http://en.wikipedia.org/wiki/Intel_Core#cite_note-19>
The first Nehalem based Core i3 was
Clarkdale<
http://en.wikipedia.org/wiki/Clarkdale_%28microprocessor%29>-based,
with an integrated GPU <
http://en.wikipedia.org/wiki/GPU> and two
cores.[21]<
http://en.wikipedia.org/wiki/Intel_Core#cite_note-20>The
same processor is also available as Core i5 and Pentium, with slightly
different configurations.
The Core i3-3xxM processors are based on
Arrandale<
http://en.wikipedia.org/wiki/Arrandale_%28microprocessor%29>,
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 <
http://en.wikipedia.org/wiki/Turbo_Boost>.[22]<
http://en.wikipedia.org/wiki/Intel_Core#cite_note-21>According
to an Intel
FAQ <
http://en.wikipedia.org/wiki/FAQ> they do not support Error Correction
Code (ECC) memory
<
http://en.wikipedia.org/wiki/ECC_memory>.[23]<
http://en.wikipedia.org/wiki/Intel_Core#cite_note-22>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]<
http://en.wikipedia.org/wiki/Intel_Core#cite_note-23>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]<
http://en.wikipedia.org/wiki/Intel_Core#cite_note-24>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]<
http://en.wikipedia.org/wiki/Intel_Core#cite_note-25>
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?
