It won't work.  The 32GB DIMMs only work with 8th gen and higher CPUs.  You have 6th gen.  Your maximum is 4X16GB = 64GB

As previously stated, the MPU in the Xeon 1505-V5 CPU will not support memory sizes larger than 64GB.

 

Xeon E3-1505M v5 is a 64-bit quad-core x86 high-end performance mobile workstation microprocessor introduced by Intel in late 2015. The E3-1505M v5, which is based on the Skylake microarchitecture and is fabricated on a 14 nm process, has a base frequency of 2.8 GHz and a turbo boost frequency of up to 3.7 GHz with a TDP of 45 W and a configurable TDP-down of 35 W. This processor incorporates the HD Graphics P530 integrated graphics operating at 350 MHz with a turbo frequency of 1.05 GHz. This model supports 64 GiB of dual-channel DDR4-2133 ECC memory.

As  said, 64GB is the maximum memory, and, as I said above, the 32GB sticks do not work with the CPU you have.  Therefore, you can use 4X16GB = 64GB.  You cannot use 2X32GB = 64GB.

Re: ThinkPad Xeon P70 128GB RAM

I have installed 128 GB in four modules of 32 GB, then the RAM modules are compatible, at least two works into my P70. Before returning the memory to the vendor, I need to know if I can overrides the OS and/or the BIOS and/or the CPU, clearly the first two can be by software (Lenovo), the uP is not possible and I can not be changed without changing the motherboard, uP soldier, If the CPU has 64 bits why it can not address 2**64 adds, Intel wants money? as Windows (servers OS) or as Lenovo that NOT updates its BIOS (128 GB in P52-72)?

The P72 and P73 will support 128GB memory and upto 64GB ECC-Memory.

Re: ThinkPad Xeon P70 128GB RAM

Intel has released a statement for the 9th Gen Core processors. It's interesting that the new SO-DIMMs are also recognized by the previous MPUs. This is a similar situation when a few years ago DDR4-2400 memory became available, but the systems were only certified at DDR4-2132. In fact, the systems actually ran properly with the new memory, but eventually a BIOS change was made to limit the memory speed to 2132MHz, but to allow the use of the DDR4-2400 SO-DIMMs. So, while it is technically possible to have 128GB in a two-channel memory system, Intel has not validated that configuration for older processors. Without that certification, I would not expect to see any BIOS update for the P70 to officially support memory > 64GB. That said, the P52 and the P72 can be officially configured on the Lenovo website at 128GB (non-ECC memory) for both Core i7 and Xeon processors regardless of the Intel documentation on their website to the contrary.

 

The Intel statement is below. There has not been any further announcement regarding previous processors. 

 

The new 9th Gen Intel Core processors memory controller is capable of supporting DDR4 16Gb die density DIMMs which will allow the processors to support a total system memory capacity of up to 128GB when populating both motherboard memory channels with 2 DIMMs per Channel (2DPC) using these DIMMs.  As DDR4 16Gb die density DIMMs have only recently become available, we are now validating them, targeting an update in a few months’ time.

 https://linustechtips.com/main/topic/983420-hp-forces-intel-to-officially-support-128gb-ddr4-on-9th-gen-core-cpus/

 

We don't know if this support is coming to 8th Gen Intel products or Skylake X products. There's no technological reason why they shouldn't be able to. They'd just need to issue a microcode update or a BIOS update for compatbility.

 

My Thinkpad is still under warranty, cost more than 3000 $ (Xeon, 64GB RAM, RAID0 1TB, 2x1TB SSD), how can I get expert technical information from lenovo?
