It was something like server xchnge or something like that? they got sets of used memory from servers that people were upgrading and sold it to others, back around 2017

Ok. I got 6 cards on the build without plugging in that extra 4 pin plug and everything worked great until my ups started beeping with an overload. I simply backed off one card to 5 and its happy now. I have to figure how to redo things or buy more expensive stuff which id rather avoid.

Maybe 7 980ti's. Would there be a problem using the 4 pin cpu connector off a second psu?

I'm doing a custom build, and my motherboard wants 2x 8 pin connectors for the dual cpu, the 24 pin atx, and an optional additional 4 pin, like a 4 pin cpu, to help power the many pcie slots if they all get populated. My 1000 w power supply doesn't have an additional 4 pin, could I use a molex...

Is ebay a good place to buy ddr3 1600 registered ram? I need to get two dual channel kits, or one quad channel kit for a dual xeon build. I'm looking for 32 or maybe 64 gb. People say buy the cheapest, but wasn't sure if there was some other store people usually get it, or is used not good...

Ok, thanks.

3d rendering...but now I use no more than 20 gb for 2 cards, if I up the cards to 4 or 6 will I need more ram because of the extra cards

Is there a rule of thumb for how much ram to install for a mult-gpu system?

That's good to know. So if I get any non-ecc unbuffered 240 pin ddr3 1600, it should work. Unlesss timings are an issue for the MB, in which case I would think SM would have mentioned something more about memory? Perhaps, it's more wide open then I thought. I've just read stories of people...

Right...I saw that too...but I don't know memory that well, I usually go with what others have gone with mentioned in their reviews on newegg. They mentioned above, 72 bit memory...is all memory 72 bit? also, I think I want to go with quad channel, so that is 4 sticks per cpu....so 8x4GB...

They only give ecc memory http://www.crucial.com/usa/en/compatible-upgrade-for/Supermicro/x9drx--f I don't need ecc and that is expensive memory

The MB specs say: System Memory Memory Capacity 16x 240-pin DDR3 DIMM slots Up to 1TB DDR3 ECC LRDIMM Up to 512GB DDR3 ECC RDIMM Up to 128GB DDR3 ECC/non-ECC UDIMM Memory Type 1866/1600/1333/1066/800MHz* ECC DDR3 SDRAM 72-bit, 240-pin gold-plated DIMMs Support ECC and non-ECC UDIMMs *...

While we are on the subject, the mb I'm getting has tested this memory, but it doesn't specify CL or Timing. Is there a stock timing that's assumed if not listed? http://www.memoryamerica.com/hmt41gu6mfr8c-pb.html

GPU CUDA 3D rendering.

After reading, I think I understand. For dual xeon setup, performance will be best when populating memory for each cpu, so if I wanted to go with 32 GB, I would populate with 4x8GB sticks, 2 sticks for each processor
