Hi There G.Skill People!
First thing's first...
Motherboard: ASUS P5Q3-Deluxe
BIOS: 2105 (26/05/09) - Latest
CPU: Intel Core 2 Q9550
RAM: F3-12800CL9D-8GBXL (2 sets of 2 x 4GB)
Problem: When the mobo has all 4 slots populated, no post.
Testing I've done: A set in slots A1 & A2 works. Swapping sets also works so I don't think there's a problem with the sticks. I haven't done a MemTest however... this is similar to a problem I logged and RMA'ed them. Got the new ones back and the exact same problem existed
I took the MB specs in with me to a local (reputable) computer chain and asked for RAM that would work reliably, and that would allow me to use the full 16GB that it's capable of taking. Oh and preferably G.Skill (due to the help you guys have given before). Here are the specs from Asus.com:
The rep gave me the above set, as they no longer stock the models that are on the QVL (it's now a bit out of date). He said they should work fine.I have not had any luck with more than 2 slots filled.
Right, now because I'm a stickler for details (and a reasonably quick typist) here's my current BIOS settings. Feel free to cut & paste them in any response so I know what to change!
I'm not interested in overclocking.. I'd just like to get the system working with all slots populated.
A few people (myself included) have had similar issues, and there never seems to have been a final resolution.

If I manage to get this up and running, I'll update the other posts to point here.
Hoping you can help!

4 x DIMM, max. 16GB, DDR3 2000(O.C.) / 1600 / 1333 / 1066 MHz, Non ECC, un-buffered memory
Dual channel memory architecture
Supports Intel? Extreme Memory Profile (XMP)
*Refer to www.asus.com or this user manual for the Memory QVL(Qualified Vendors Lists).
** DDR3 2000(O.C.)/1600, it is suggested to use one DIMM per channel
***When installing total memory of 4GB capacity or more, Windows? 32-bit operation system may only recognize less than 3GB. Hence, a total installed memory of less than 3GB is recommended
**** It is recommended to install the memory modules from the orange slots for better overclocking capability.
