Now the problem I had with this is that every time my computer would wake up from sleep, my fans would go nuts for about 15 seconds and run to 2500-3000 RPM's. My idle speeds were at 1100-1300.
I tried everything from reseting SMC, PRAM cleaning out caches, and re installing the combo updater until I finally just decided to take the ram out. Idle's went back to 500 RPMS, and no problems.
Now I have it configured it :
So my Ram looked like this:
Riser A Slot 1 - 2GB
Riser A Slot 2 - 2GB
Riser B Slot 1 - 1GB
Riser B Slot 2 - 1GB
Riser A Slot 3 - 512MB
Riser A Slot 4 - 512MB
Riser B Slot 3 - 2GB
Riser B Slot 4 - 2GB
And my fan speeds seems to be just right, idling around 500. Temps are a bit higher (30C to about 35-40C, so I just bump up my fans using SMC Fan Control.
I know I've seen lots of threads where there is too much dust build inside and can cause this, but I've already done this with no success and checked to see if my heatsink sensors were plugged in.
Anyways, sorry for the long story here, but can anyone tell me the correct configuring my RAM? And can anyone explain why my fans would go nuts when the CPU temps are just normal?

This should work for you:
Riser A Slot 1 - 2GB
Riser A Slot 2 - 2GB
Riser A Slot 3 - 2GB
Riser A Slot 4 - 2GB
Riser B Slot 1 - 1GB
Riser B Slot 2 - 1GB
Riser B Slot 3 - 512MB
Riser B Slot 4 - 512MB
This is exactly how my RAM is configured.
Or it could be your new RAM is DOA or of the wrong type.
Sorry no idea re:why your fans keep going.

I found this guide to help with configurations for best performance I guess which tries to make matched pairs on the 1&2 slots on A and B - which takes advantage of a 256-bit wide memory architecture.
That being said, Ill try your way screature and put all the 2GB on A.

So i just tried to put all the 2gbs on Card A. From sleep my fans do ramp, but only to about 1700 RPMS.
Maybe configuring it to 256 wide on and trying to balance a & b will trigger something to make sure all the built up heat from sleep is forced out?
I do have the correct ram PC 2 5300 ECC FB 667

The guide is correct, the fastest configuration is to have all 4 of the 2 GB modules in the 1 and 2 slots == A1 A2 B1 B2
The 3 and 4 sockets are slower than the 1 and 2 sockets.
We are suspecting a problem with the heatsink on one of the new modules, we're shipping replacements, so don't sweat this any harder until you get your new modules to try.

Thanks! I did get your email, and thanks for taking care of me here!

Ramping of your fans from sleep is normal in my experience...
I tried installing the RAM in the recommend 256bit manner you describe and I was never able to have all the RAM showing in system profiler, putting all 4x2GB modules on the same card was the only way I was able to get all the RAM to show up... I can't explain it but I just had to go with what worked for me.
Yep you definitely have the correct RAM.

Do you have the 8 core 5365's in your 1,1?
How fast would fans start to run @? Mine kind of acts like that sometimes but is specific to the Apple 1GB sticks. Sometimes it would not be detected and the red light on the daughter board would come on. I just down pull the card out and then back in and it seems to work for me after the restart.

Any idea why if I install my RAM in that configuration it comes up 4GB short and when I put all 4x 2GB in the top riser the system profiler show all 11GB? I got the same sheet from you when I upgraded to 11GB, I did the same thing as mlke.

No I have dual Xeon 5160s (dual 3.0 GHz) for quad core.
