16 core/32 thread/64GB RAM Mac setup, but not fully working yet.

Sweet fancy Moses!

I was finally able to get full res playback at 24 FPS. I have to wait for it to cache. But it loads a 60 second 5K R3D in RAM, and plays back and scrubs in realtime. I guess that's normal for anyone though, so nothing special.

how long it take to cache it in RAM ?

thanks

24.5 is a really good score, but in my opinion is not enough for realtime full debayer with 4k redone footage... but you have a beast for after effects!.

5K, 4:1, 30 second clip took around 5 minutes to fully cache with a Samsung 830 SSD. RAM usage is 1GB per 1 second of footage (30 second clip is 30GB for RCX app). So I'm sure a 120 second clip would take up all the system's 128GB of RAM, and max out in full res.

Same footage, 1/2 res took around 2 minutes to load, but much less RAM of around 7GB. 1/4 res took about a minute.

It plays back that footage at 23.98 fps smooth as silk, and scrubs clean, as fast as you can move the mouse.

Since I've never used a Red Rocket, I have no clue what the norm is. Maybe someone can tell me.

RED Rocket can cache your frames at real-time, or even a bit faster depending on which R3D format. Where most people run into issues on playback and scrubbing is with their available RAM. RC-X seems to do some funny things when it comes to how it manages that cache. On playback it tends to run to the end of the cache and then begin cacheing more, so you can run into stuttering, even with the Rocket. But I think it's this way more so that you can continue to scrub back and forth and tweak your look rather than just playing back endless minutes of footage.

While I'm thinking of it, what RAM did you install for your 128GB Joseph? I'm still waiting on my motherboards, and therefore waiting until they arrive to order my RAM. Selection of proper RAM out there sucks. 1600MHz modules are hard to come by, near impossible for ECC memory. As of right now, I'm probably going to install 128GB via 16 x 8GB of G.Skill Ripjaw X modules. They're available as PC3-12800 (1600MHz) with 9-9-9-24 timings. Mushkin also has the same product in their Blackline series, but it's more expensive and harder to get ahold of. I've been having good luck with G.Skill lately in other systems. Mushkin too, I'm partial to them, they're located near me and I'm kinda biased. :)

There's also the Kingston HyperX 1600MHz ECC modules, but they're at CAS-11 and seem to perform rather poorly overall.

Since supermicro is really picky with RAM, especially with that much RAM, I bought the certified memory from the X9DAI drop down menu.

Samsung M393B1K70DH0-CK0 is the 8GB module. Works perfectly with 16 sticks. I think it's CAS 11 at 1600MHz.

Cool. I'll take another look.... Ah they have more RAM listed there than the last time I checked.

Pulling the specs, both the Samsung and Micron models look nearly identical for the ECC 8GB modules. Samsung are CAS 11, Micron are CAS 10. I'm going to call my guy at Micron and see what he says. According to when I talked to him last week, they didn't have any modules with these specs...? But their site says it's in production and Supermicro has them on their approved list, I'll see what he says. I can't seem to find them for sale anywhere.

[Paul Schneider]

Very interested in setting something like this up. Can you post a list of components or direct to a site. Thanks.

[Joseph S.]

@Paul, here are some parts below. Obviously the cpu, mem, drives, video cards are all your choice.

I'm still waiting for the EVGA SR-X as it might work better with MacOS, but it's still unknown.

Chassis/case:

Board (installed/wired with case above):

CPU:

256GB SSD drive:

The EVGA SR-X has 12 memory slots, and not 16. So the max RAM using 8GB is 96GB.

And the Asus board has 8 sticks, but it's not the C606 chipset.

[Jeff Kilgroe]

If you populate all the slots on the SR-X board, I believe it will drop the RAM to running in dual-channel mode. I'm still waiting for more info on the board... Can't say I'm too wild about the PCIe configuration either.


ASUS board looks alright for smaller configurations, but I haven't really looked at it.


I just ordered a bunch of RAM for my two incoming SuperMicro boards using the 8GB DDR-3 Registered ECC 1600MHz modules from Micron. They're kinda pricey and in short supply. Their part number is: MT36JSF1G72PZ-1G6M1 and is listed as being tested/approved on the Supermicro X9DAi product page. I ordered direct from Micron.
