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

Ok, thanks.

I'm building my first dual cpu system, do I need to get the same amount of ram for each CPU, and does this add up or equal half the total? Like, if I do need to get same amount for each, and I buy 16 gb (2x8gb) for each CPU, does this equal 32 total, or 16? Also, is it good to go with ecc ram?

OK...I was just curious. After doing more research, and yes this will be for 3d GPU CUDA rendering, what if I went with a server board with many pcie slots like a supermicro motherboard. Also, I'm thinking of running dual xeons (older generation like 2670 v2)...would this setup be similiar in...

Intel says my 3770 k can run 1 at 8x and 2 at 4x. If I used a 4x pcie splitter to 4 cards, would this work? Does the splitter act like one 4x config as far as the CPU is concerned. Can I still run one at 8x with the 4x splitter? Tia. So 5 cards altogether.

Can on board handle 3ds max viewport?

4-6... when I putting a 3d scene together, and creating materials and adjusting lights, have the real time rendering helps speed this up...vray rt gpu mode works with multiple gpus, so 4-6 might work well. I would probably run one card in the MB to run my monitors, then the rest with a 1x pcie...

Thanks, I wouldn't have thought to search for something like this.

I'm looking at building a 3d animation workstation with multi gpus to help with real time rendering. Instead of plugging in all th gpus into the MB, I would plug only the card(s) needed for the monitors, and use riser/extender boards for the additional gpus. The large psu's and corresponding...

I should have specified this will be for data transfer only, no graphics output. The GPU rendering in this case will be on render nodes...they are not hooked up to any monitor. They exist to receive a 3D file, render it, and transfer the image file back to a network location.

I'm considering mounting my GPUs outside my box for cooling during 3D GPU rendering. The adapter I'm considering has a 1x card that plugs into the MB and a USB 3 that connects the GPU plugged into a 16x adapter along with power to teh 16x adapter. I'm wonder if there will be siginicant...

Thank you.

OK, thanks. Someone showed what MBs to look at, they explained the cpu lane requirment, MB, etc. Once I looked, I started figuring it out. Thanks for the info on the PSU, I'll do some calculations and see what I get. Thanks again.

Thanks for the laughs! I didn't know I would get so many replies on the subject...I'll have to finish reading them later. Gotta go flash my BIOS in 4 seconds. ...just kidding.

I need to update my bios so I can use the i5-4690K cpu and on the website asrock says use bios 2.70 for this chip, however, they have newer bios versions on there too. Should I just use the newest or go with the 2.70 that was required for that cpu. I'm wondering if there was something in the...

I just need to flash the bios on my mb with the celeron cpu so I can run a different cpu. Is it safe to do without mounting the heatsink and paste ?

The advice from my fellow 3D guys is it's better to build a box with, say 4 GPUs, instead of two boxes with 2 GPUs each. They say it's more cost effective, but I'm having trouble finding a MB with 4 slots? Also, when the pciex speed is reduced with multiple GPUs, does that effect efficeincy...

Thank you. I'm going to be doing this on 5 mb's with 1 celeron cpu in order to flash the bios' for the target devil's canyon cpus.

Thank you...maybe I wasn't searching correclty on google.

Do the pins get smashed with the first cpu? Is there a risk the second cpu won't connect proplery due to smashed pins from the first cpu?

Anyone heard if this is easily doable with an asrock z87 extreme4 board? Google isn't bringing up much.

Thanks

(Sorry this is a duplicate post...I posted in the MB forum with no answers...but I need to get this going before Monday) My Mb is an asrock z77 extreme4. This board has a 24 pin power plug that I've read I use the power supply's 20+4 pin with. The board also has an 8pin ATX 12V power...

This board has a 24 pin power plug that I've read I use the power supply's 20+4 pin with. The board also has an 8pin ATX 12V power connector. The manual says use a 8 pin atx 12v, or a 4-pin atx 12v will work if I put the connector towards the pin 1 and pin 5 side of the 8 pin plug. My power...

Oh sorry...I thought I was to separate my posts into categories.
