Best memory for Precision T7600

Hi @Guswah ,

Depends on what your "Best" stand for. Take a look on the following table regarding T7600 memory configuration:

NOTE:

• Table above show all configurations are ECC RDIMM.
• * 512GB configurations required load-reduced memory and are 1333MHz speed only.

The "32 GB LRDIMM ECC, both 1333 and 1600" mentioned on manual do not stand for maximum number of total memory in T7600. It means a kind of memory named as load-reduced memory, 32GB on a single stick, frequency at 1333MHz or 1600MHz.

• If you need to pump up your T7600 to it's maximum possible size of total memory, i.e. 512GB with dual CPU, you need LRDIMM.
• No matter if you're using 1333MHz or 1600MHz LRDIMM, they run at 1333MHz only on T7600

But if your "Best" stand for maximum possible size of total memory at maximum possible frequency, i.e. 256GB memory at 1600MHz with dual CPU, you don't need LRDIMM.

Further to your question about those letters:

• "R" of 10600R - means "Registered"
• "L" of 14900L and 12800L - means "Low Voltage"

As highlighted above, T7600 require ECC Registered DIMM. And for voltage, as mentioned in the Dell document you quoted that DDR3L compatible with both 1.5V and low 1.35V, it works on T7600 as well. Reference from T7600 builds on Userbenchmark, we can find builds like this one installed with DDR3L (Samsung M393B1K70DH0-YK0) with a not bad benchmarks.

Hi @Guswah ,

Further search and found this thread regarding a member's T7600 installed with DDR3 PC3-14900L 1866Mhz RAMs. You may take it as reference and left message there to sink for more information.

If you find any reply above helps, please consider mark it as solution in order to benefit those with similar question. Thank you and good luck for your hardware upgrade project!
