T3600 does not recognize new RAM
I have a T3600 that had 2x2GB PC3L-10600R RAM sticks. I bought a 16GB kit offline (4x4GB) of PC3-10600R RAM (note I opted not to get PC3L or Low Voltage RAM as I was told I would not need it but I did stick with ECC over non-ECC as it is much cheaper and my machine can take either type.)
Anyways, I install my new RAM in place of my old RAM and all I get is Diagnostic LED 3 & 4 lit. No video or beeps. I tried just one of the new sticks in slot 1, but nothing. I put the original RAM back in and decided to ask for advice as I am not accustomed to working on servers/workstations as much as I am regular consumer PCs.
I did follow everything mentioned in the link below, but no luck.
Thanks for any help!

All that great information and still not a single word or phrase about "Low Voltage" RAM and if this system needs it or not. After confirming it would not take "Regular Voltage" ECC PC3-10600R RAM, but would take the Low Voltage PC3L-10600R that it came with, and will also take my regular DDR3 non-ECC RAM (not mixed with the ECC), I looked on Dell's site and clicked on Parts and Upgrades, then RAM. They offer ECC and non-ECC, but the only ECC type they offer is Low Voltage. And it doesn't say it straight out either, I had to look up the part number of the RAM module they were selling just to find out it was a Low Voltage module.
It seems this machine REQUIRES Low Voltage RAM if you are opting to go with ECC. If you want to use regular non-ECC DDR3 RAM, you do not need the Low Voltage RAM.
Again, not a SINGLE word or bit of verbiage in any Dell provided paperwork or documentation about needing to use Low Voltage RAM, yet it IS a requirement. Wasted time and money on the RAM, and now have to pay a restocking fee on top, because Dell didn't document ANYWHERE what exact RAM type it requires.

You can click the link below to view the online manual. The manual provides information about the memory.
Dell T3600 Drivers, Downloads and Manuals
MemoryThe Precision Workstation T3600 system supports up to 64GB of memory on single processors with 4 DIMM slots available. The memory speed supported is 1333MHz and 1600 MHz DDR3 unbuffered or registered ECC SDRAM memory. DDR3 SDRAM or double-data-rate three synchronous dynamic random access memory is a random access memory technology.
This system is on Intel LGA 2011 platform, supports DDR3 Quadruple-channel architecture.
Dual-channel architecture
Dual-channel-enabled memory controllers in a PC system architecture utilize two 64-bit data channels. Dual channel should not be confused with double data rate (DDR), in which data exchange happens twice per DRAM clock. The two technologies are independent of each other and many motherboards use both, by using DDR memory in a dual-channel configuration.
Triple-channel architecture
DDR3 triple-channel architecture is used in the Intel Core i7-900 series (the Intel Core i7-800 series only support up to dual-channel), and the LGA 1366 platform ( Intel X58). According to Intel, a Core i7 with DDR3 operating at 1066 MHz will offer peak data transfer rates of 25.6 GB/s when operating in triple-channel interleaved mode. This, Intel claims, leads to faster system performance as well as higher performance per watt.
When operating in triple-channel mode, memory latency is reduced due to interleaving, meaning that each module is accessed sequentially for smaller bits of data rather than completely filling up one module before accessing the next one. Data is spread amongst the modules in an alternating pattern, potentially tripling available memory bandwidth for the same amount of data, as opposed to storing it all on one module.
The architecture can only be used when all three, or a multiple of three, memory modules are identical in capacity and speed, and are placed in three-channel slots. When two memory modules are installed, the architecture will operate in dual-channel mode.
Quadruple-channel architecture
The architecture can only be used when all four, or a multiple of four, memory modules are identical in capacity and speed, and are placed in quad-channel slots. When two memory modules are installed, the architecture will operate in dual-channel mode. When three memory modules are installed, the architecture will operate in triple-channel mode.
A NOTE indicates important information that helps you make better use of your computer. NOTE:
Memory modules should be installed in pairs of matched memory size, speed, and technology. If the memory modules are not installed in matched pairs, the computer will continue to operate, but with a slight reduction in performance.

Standard name Memory clock Cycle time I/O Bus clock Data transfers per second Module name Peak transfer rate
DDR3-1600 200 MHz 5 ns 800 MHz 1600 Million PC3-12800 12800 MB/s
DDR3-1333 166 MHz 6 ns 667 MHz 1333 Million PC3-10600 10667 MB/s
A NOTE indicates important information that helps you make better use of your computer. NOTE:
"N" configurations are built with non-ECC UDIMM memory. All others are built with ECC RDIMM.
DDR3 DIMMs have 240 pins, the same number as DDR2, and are the same size, but are electrically incompatible and have a different key notch location.
