Is my mobo defective? gigabyte

[XMASVL]

Just put together a new build
got a thermaltake 600W PSU
intel pentium G3220 @ 3.0GHz, 54W
and these

all on a Gigabyte GA-H81M-HD2

when putting it all together at first it wouldn't boot at all, no fans, no led, no beeps
after reseating everything, it booted with a series of ~39 short beeps, then it shuts off
this is now what happens whenever it starts unless i take out the stick of ram closest to the cpu
i've switched the sticks out, and either of them work, just not when one is plugged into that slot

is the slot fried? I hear some mobo/cpus or something require only one stick of ram/ram in one specific slot before setting it up in the bios

is this an xmp thing? my bios shows the mem freq at 1333 but i haven't turned xmp mode on

Actually if you read the manual, your supposed to stick the SAME exact memory sticks in two specific slots. For example Slot 0 & 2, then for two more sticks in 1 & 3 and so on. PCs have has DUAL Channel memory for a long while now with the multicore chips. So they need the memory stuck (as per your manual) in specific slots to work together.

FYI, your manual (again the best source of info) would have listed the SPECIFIC beep patterns and you would know based on that SPECIFIC beep pattern what the 'failure' point is.

All in all RTFM.

1) It only has two slots
2) they are exactly the same, i bought them as a set
3) the bep pattern for this mobo for "continuous beep" is PSU failure, but everything else works fine, I'm using it now

Okay that would mean there wasn't either enough power to the board (PSU failure) or one of the RAM is defective. So try this.
Try one memstick slot 1, then swap mem stick in slot 1. What are the exact results of both mem sticks.
Try one memstick slot 2, then swap mem stick in slot 2. What are the exact results of both mem sticks.
Try both memsticks, confirm PSU beep code, swap mem stick, does it do the same beep code (it should if it doesn't then yes the Mobo might be hosed up).

Sounds like it may be a problem with the motherboard.

For settings, configure the RAM to DDR3-1333 8-8-8-24 1.50V and see how that works.
