Precision T3500 Ram

I ordered About 10 sticks of Dell SNPP9RN2C/8G For my T3500s , These are 8gb PC3-10600 sticks.

Here is a link. ( it is the 1st Type of Ram offered) 
http://accessories.us.dell.com/sna/PfydFeaturedCategoryResults.aspx?c=us&l=en&s=dhs&cs=19&mfgpid=201440&chassisid=8560&stype=2&Tab=

After putting these sticks in a t3500 I was receiving "non optimal ram config" error (the bios see's the 8gb stick). I could not get rid of this so I tried to only put the 8gb stick in. This caused the pc to not boot at all.

After looking up some stuff I found the tech manual for the t3500. Reading this I found out the t3500 only supports up to a 4gb stick per slot. Then I thought why would dell make this the 1st option when you go to purchase upgrades for a t3500. Also, On the web page for the the RAM, The 1st table does not show the t3500 listed for compatibility. However, The list lower on the page does.

Now after all this I Find BIOS update A11 says this under "fixed & enhancements" "Enhanced the memory map algorithm for 128GB configuration" . After installing the latest BIOS update (A17) and trying the ram again, Only putting the 8gb stick in , I still dont boot.(http://www.dell.com/support/drivers/us/en/04/DriverDetails?driverId=J7N1X&fileId=2964784371 )

Does A17 not contain this memory change? Why would dell offer this ram for the t3500? Or am I just missing something?

One more thing...check www.crucial.com for RAM suitable for this model. Crucial is very good at identifying and supplying RAM that works in Dell systems, at reasonable prices.

There's no such thing as "Dell RAM". Dell uses RAM from various suppliers. And not always the same brand in otherwise identical units. You can install the free CPU-Z which will identify the brand and specs for the RAM that's currently installed. There are other free apps that do the same thing. As for whether it has to be ECC or non-ECC etc, check the requirements listed in the service manual which you can find by clicking Support at top of any forum page and following the links.

This chart suggests that 8, 10 and 16 GB configurations aren't possible but surely I could mix DR 2GB with 4 GB as well. would such configurations not work?

@ SpeedFan

Are you sure Dell Precision T3500 can use PC3-12800 DDR3-1600 RAM? As far as i could find, it can only support  PC3-10600 DDR3-1333 only.

Can you tell more on this please if you have any info?

There are 6 slots and 24 Gigs is max.   6 Pieces of 4 Gig Ram is max.

You cannot mix ranks and density.

My Dell T3500 works with 8gb sticks with no issues.

Currently have Xeon 3565 and 8GB x 3 = 24Gb of none-ECC memory with the latest currently available BIOS.

I haven't tried installing more memory because as far as I know CPU I have doesn't support more that totally 24Gb of memory.

Will try to install more memory after upgrading CPU to Xeon 5600 family.

DDR3-1600 will downclock to DDR3-1333 per the programmed SPD settings most of the time. Crucial just lists them as compatible, not saying that they will run at 1600. I currently have a set of 6x4GB 1333mhz chips running at that speed in my T3500, but if I look at CPU-Z, I can see SPD settings for slower busses and timings.
