Dell Precision T1700 - RAM Mixture
Hi All,
Not sure if i am at the right board but here's my question.
I have a T1700 and would like to know if it is possible to have a mixture of RAM in it? For example, 16gb, 4gb, , 4gb and 8gb.
Or do i have to have the same as in 8,8,8,8 (since the t1700 can support a max of 32gb) ?

There is no actual spec listed for that post.
Its not a simple Yes or No depends on other factors.
Low Density and Rank 1 or 2 and speed and voltage all matter. Quad Rank ram is NOT supported. Mixing Rank and speed and vendor and size is not supported. ECC is ONLY for Xeon units. Mixing ecc and non ecc is not supported.
Processor has the Memory controller so ECC is ok for Xeon units but NOT for Core I3 I5 I7 units.
Up to 32GB DDR3-12800 1.35v ECC;
Intel® Xeon® CPU E3-1200 v3 product family
or
4th gen Intel® Core™ CPU, formerly code name Haswell.
Up to 16GB DDR3-12800 1.35v non-ECC DDR3 memory;
4 DIMM slots
DDR3-12800, 1600 MHz 1.35v low density INTEL compatible Ram

L-Goh,
Below are the memory specs for the T1700.
Dell - Dell Precision T1700 - Essential Knowledge

This seems like a good thread to bring together all memory related issues. So, here are some further questions on Precision T1700 RAM. I am getting a Mini-tower version of this soon. So, here are my questions....

As a rule, you may not use ECC and non-ECC memory together as well as registered and un-registered RAM.
Also, you may not mix RAM voltages.
They must be uniform in those specs, as the memory controller will be confused on how to treat the ram. There can be minor variances in the timings, but usually the system will select the slowest of the ram sticks' reported speeds to run them all at.
This applies across most computer systems and is not limited to the Dell T1700.

Can I run 32GB of non-ECC in these?

HI,
This is an old thread but a new question for me.
I am thinking of buying a T1700 but it has only 8GB.
I want 32 but not sure like in this thread what will work.
I don't know what they have in the box so far but I have seen these on sale.

Would they work?
Thanks

I want to know the same thing, ECC memory works perfectly in Xeon processors, but in my i7 4790 the pc can boot.

When I had Xeon processor in my Precision T1700 I installed 32gb ram (4 x 8gb) memory rams and it works fast, I'm not using it anymore because Intel i7 can't work with ECC rams.
Rams that I was using: Micron 8GB 2RX8 PC3L-12800E SDRAM DIMM ECC Unbuffered/Unregistered model: MT18KDF1G72AZ-1G6P1ZG.

"Can I run 32GB of non-ECC in these?"
Yes. Non-ECC is supported in 4x8G
"Can I run 16G chips?"
No. I mean, perhaps you'll get lucky, but it is not supported.
"Can I run 8G and 4G at the same time?"
No.

I have the SFF and have two slots populated with PC3 12800s so far. I have some 10600s and some 8500s laying around. Can I mix these in with the 12800s?
I got a Xeon on this Precision.
Another question. I have 1 stick of 12800 as well. Can I use this for one slot and leave my other two slots populated? Or do I have to have both extra slots populated so all four slots are used. Otherwise I would have 3 slots populated. Does this matter?
