  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

THE beast 32 core HACKINTOSH is ready.....CS6 vs REDROCKET

Still trying to find what is a bottle neck in my x9dai system since i get so poor performance in davinci resovle with 4k r3d files. I would expect it to be realtime at half res and premium debayer, or atleast good debayer. Is there any good programs to measure where the bottle neck is? I start to think its still the disks where I have atleast 500 read/write.

Well, what are you expecting in terms of half res with full debayer quality? Are you expecting to actually work and grade at that resolution? You should be able to in some capacity without the Rocket, once your footage is cached. 64GB RAM is actually kinda small if you're caching more than 15s or so and stacking on several nodes. If you're using denoise or blur/soften/sharpen nodes, those really slow you down. What sort of speed do you get for playback without any correction nodes? What about in Premiere?

If you're still experiencing bottlenecks, I would first look at the RAM. See if you can run some speed tests and other diagnostics for your RAM and drives.
 
I must confess I didn't understand that those opengl calls were obsolete.

But, I'd heard that opengl performance really dropped after the GTX-285 - and as there was a CUDA call that performed the same task (as the obselete one) and ran at 'normal' speed, and the GTX-580 ran the obselete opengl call much slower than the same code in the GTX-285. So, I assumed nVidia was possibly up to some tricks to preserve the maybe 1/4 of their income they derive from the 'high end' cards which only they sell.

I'm in total agreement with you about wishing nVidia would offer less SKUs - and feel annoyed that I'm not champing at the bit to purchase the 680/690 which has much better cooling, 4GB VRAM, etc. - due to the possibility that it's performance will be lackluster.

I may spring for it just for the extra 1GB VRAM and better cooling ... as, what's the alternative?

Great company that nVidia is for bringing us CUDA, I just wish they would make it easier for me to give them my money.

Without any cc nodes I get 1-7fps and its plays a frame chookes, plays a few, chookes. I dont even se green or red bars in the gpu meter. If I open a project with the alexa footage from black magic it runs with no problem at 24fps and the gpu meter is constant green. Did not find any candles test xml files that worked with resovle 9. Otherwise I would checked that out. Premiere runs smooth at 1/2 res.

What program is good to check the ram?
 
Here's a thread with links to the candle test for Resolve 9:

WOW. How much does building one of those run you?

CS6 5k for now all in real time full frame at full resolution ..... without redrocket.:emote_22_yikes:

Just did the candle test and only get realtime with 6 blur nodes (deleted two from the 8 blur nodes).

As i understand it you dont have much use of the gpu in resolve until you adding colorcorrect nodes. But perhaps im wrong. Would be great if some one with realtime could turn off all gpucards and use only one card for both ui and gpu. Best case would be a x9dai user with dual xeon. If you cant turn cards of and pull them out physicaly its a big favor to ask.

Also my ram with this Samsung 8GB DDR3L ECC REG 1600MHz DR x4 1.35V
Was this a good buy?
 
I'm about to pull the trigger and sell my Mac Pro and build a Hackintosh.

My biggest concern is stability...I'm sure that most of it has been ironed out though.
 
any idea on how much to budget for one of these?

A lot... I still cry over what I have invested in my Z820. Close to $15K not including monitors and other external goodies.

X9DAi build as it sits here now is just under $9K with dual 2687W, liquid cooling, 128GB RAM, GTX690 and 512GB SSD. It also makes me want to cry.

Joel, I will do some benchmarks with the candle test this weekend and report back here.


For memory testing, I would start with a couple common free utilities. memtest86 isn't bad, but could use some updates for newer systems and instructions. It will test all of your RAM. Then there's also CPU-Z from cpuid.com - it can help test performance on some operations. If you have any real problems these two will turn them up. If your problems are more serious, it may take some more specialized software. That is rare though... Typically if your problems are more severe then you're crashing left and right anyway.

Samsung makes a few different DIMMs with those specs, some are tested and approved by Supermicro to work with this motherboard, some are not. Not saying that the unapproved ones won't work, but for these bigger workstations it's best to buy off their approved list. I know from the specs you just listed that you're using modules that have not been tested and approved. Supermicro has not tested or approved any 1.35V LRDIMMs at 1600MHz... Not sure if that means anything. The currently approved 8GB module is part # M393B2G70BH0-CK0 -- they sell for about $165 each here in the USA. These are what I'm running on my X9DAi and they work fine.
