128 GB DDR4 question

Is 128 GB of DDR4 ram that tricky to get running right? A computer guy told me that not all cpu's etc work right with that much ram. Anybody have exp with that much ram on a x99 MB?

Possibly slightly off topic, but that much memory almost necessitates ECC / Buffering. Single--bit errors occur as a function of memory size, that much memory means random little corruptions will occur more likely on a per-system basis than on a more "normal" system with 8 or 16GB of RAM.

On a more on-topic note, occasionally occupying all DIMM slots requires looser timings and possibly not even using the memory at it's highest rated speed. Aside from that, it should be plug-and-play. Checking the manufacturer's recommended/tested memory list helps with applications like this.

We deploy a LOT of Win7/10 Enterprise workstations at work, but they're all running ECC ram in HP workstations. So far we haven't had any issues with that amount of ram or getting it to work properly, but we're also not using the X99 platform >_>

I'll scale back to 64 GB then. Glad I asked about this before I bought that much Ram. Thanks

X99 is designed for it. Overclock will likely be limited having all the channels populated with the largest supported non-ecc sticks though.

still haven't read this hahaha but this is the only good article i have seen posted on about actual ram error rates. Everything else is hearsay.

if you got better or newer documentation on the topic please pm me it

Korrect.

I've only seem that scale on ECC ram. I'd be curious to see how it works with Non-ECC

I would have thought power draw/drain might be an issue on some boards.

My 5930k / Asus Sabertooth X99 drives 128GB just fine. I'm using 8x16GB DDR4 2400 Crucial memory and I can still overclock my CPU to 4.5GHz at 1.19V. You will need to update your BIOS to a version that supports 16GB dimms.

I'm working on a build and it's increasingly looking like this will be a question I'll need to answer as well. It's looking like I'll go X99, and my mindset tends to be "If it's there, fill it up" so I was figuring I'd just roll out a 128GB kit and call it good. I probably won't upgrade for another 6-8 years anyway.

It looks like there are some concerns though. I'm a little curious: If ECC is a big issue at higher capacities, what's the logic behind supporting 128GB of RAM that isn't error correcting? Have the major manufacturers just gotten production methods to the point where it's reliable enough to not be a major consideration, or is this likely to cause premature failure? I also heard someone suggesting to buy all the RAM you want to add as a kit, which seemed foreign to me -- I've always gone by the rule that same manufacturer and model/series was good enough. Are the larger capacity sticks getting finnicky enough that this is no longer true?

What are the respected brands on the big end these days, anyway?

I just built a client a new workstation with 128gb no-ecc. Working flawlessly.

Gigabyte GA-X99-Designare EX paired with an Intel 6950x 10 Core and 128gb of, can't remember the maker. Corsair 2400mhz something. AMD Firepro w9100 16gb.

Incredibly fast.
