I just got four 2GB memory modules for my computer (running on 1 GB was starting to try my patience). These were destined for the four slots on my motherboard (Intel DG965RY).
These combinations produce a happily working machine:
any one DIMM in any slot any two DIMMs in any two slots any three DIMMs in any three slots
This combination produces a machine that can't get as far as the BIOS power-on self test:
all four DIMMs in all four slots
It fires up the fans and stuff for about five seconds, then shuts off. Then it waits about five seconds, and fires up again...and it repeats the cycle, endlessly, until I pull the plug.
Has anyone seen this sort of thing before? All of the DIMMs and all of the slots have been proven to work in isolation or combinations up to three...it's just when I try to use all four at once that it conks out.

Any beep codes?

What are the specs on the DIMMS, PS, and energy draw of the devices?
I'd be surprised that 4 DIMMS would cause too much power drain, but as others have commented,
that is the symptom. Insufficient power, bad MB, or bad BIOS. Is there an updated BIOS for your MB?
Technically, your stated scenario should not work. There is only one supported configuration for three DIMMs on your MB. In your case you are wanting to max out the memory to 8GB. With three it should be this configuration: Channel A: 2 matched 2GB DIMMS Channel B: 1 4GB DIMM in DIMM 0. All same speed.
Some of your configurations are probably producing single channel memory operation. Probably not healthy for either the memory or your system.
With, 2 DIMMs you should be using a matched pair in slot DIMM 0 only (channel A & B). With 4, a matched pair in DIMM 0 and another matched pair in DIMM 1. With 3, a matched pair in Channel A, and one of twice the size in Channel B, DIMM 0.
Just curious, but what type of DIMM are you using? Also, I think that board can't run 8GB at 800MHz, as you need 1GB memory DIMMS and the MB doesn't support 1GB @ 800MHz.
So if your chips are 800 MHz, that may be the issue.

Hi all, thanks for all the feedback.
I hoped to devote some time to this over the weekend but I didn't get enough time to solve it. However, I did manage to pull some more info.
These are the memory modules in question... http://www.newegg.com/Product/Product.aspx?Item=N82E16820178164 (I ordered two sets of two.)
Also I've attached a photograph of the memory config page in my BIOS. If you take it off of "automatic" there are two manual options. One of them just lets you make changes, while the other, called "aggressive", assigns some values but lets you change them.
I couldn't find any settings for memory voltage, but is that implicit in these settings?
I did toy around with changing some of the settings, mainly forcing it to 667 MHz as that's what the memory is really supposed to be rated for. For the others I tried a few changes but not much as I didn't know what was plausible. Nothing allowed all four sticks to work at once.
If I'd had more time to spend, I'd have done better research on what the settings mean, etc...sorry not to have done so yet.

My only remaining suggestions are: 1) return 4GB of memory and replace it with a single 4GB DIMM (there's on on NewEgg that matches by speed and latency), 2) replace the MB.
Sorry but seeing as how you have DDR2 667MHz DIMMs, which theoretically are supported, and they don't all work there aren't many options. If you try removing a device, as suggested by another, to reduce the power load, and that doesn't work, and you've manually set the timings to match, and none of that works, well there's not much else to do. Unless you plan to do CLD on the MB.
Good luck, Jack
