Only two FPS games I was ever into were SOF and Jedi Knight 1-2... But I were never into games, they couldn't really live up to my reality... :D

This was 3 years ago, me at 43yo, imagine what I've been doing over the previously 40 years... ;)

Scary :P you do know there was a road to the left right? :P
Ramberget, you still live on Hisingen?

Im more of a inlines kinda guy :) but no boring ass rolling on a straight line. Started when i was 14 on Hisingen ;) i practically lived on my Aggressive inlines, i bought a pair of freeskates 2 years ago and it all came back to me after like 14 years of rest haha :)

I started in skateboarding, was even sponsored for a while by Per Holknekt's company/skateshop "StreetStyle" in the late 1980s, but then I went onto MTB, BMX and also did aggressive inlines - Johan Sunde was a close friend of mine. And yeah, I lived in Långängen since I moved back from London in the late 1990s. :D

And skateboarding was what got me into photography, selling photos of extreme sports, which got me work as a pro photographer (on CitiNytt, a Nöjesguiden type magazine back in those ancient times) which got me into computer graphics... 30 years later I'm doing FX work in Houdini. What a trip. :D

That moment when you realize you RAM slots are full, all 16 of them, and that you will have to settle for the 128Gb RAM you have. :?

Followed by that moment when you're on your knees, praying to a non existent deity from bronze age mythology, for the machine to boot. :D

The benchmarks are kinda surprising, though, I thought ECC was supposed to be "slow" but I suspect that might be a question of the definition of slow.

Why would they be slower? if they have the same speed and cas latency and using quad/triple/etc channel they should be just the same, more or less at least :) I dont think the Error checking or whatever it is ECC have should make them that much slower :)

Im also thinking of maxing my memorys to 128 just for the fun of it :P I havent even got started with my computer and already thinking about upgrading lol

Oh yes, ECC should slow them down considerably - though once again, I suspect that might be a question about what measurement we are using, the scale. In benchmarking, one person's panic is another person's meh. ;)

Looking at your chart and the memory amount used then my guess is that they only have 1 stick while you have all yours and in your case you get the tripple channel so alot more bandwidth. If only one stick is used then you aint getting all that extra bandwidth.

Some other charts here: https://www.pugetsystems.com/labs/artic ... mance-560/

EDIT: I first wrote "Quad channel even, not triple. And yes, that's not unlikely."

...but then I watched this, and as with everything else in RAM, seems the channels doesn't make much difference either... :D



And we talked a lot about RAM before in the hardware threads here at VCP forums - especially in regard to if it's worth buying something like a 6700K compared to a 4790K seeing the DDR4 RAM - so I already knew there really were no difference between DDR3 and DDR4, etc, but watching the Linus Tech Tips videos (with benchmarking) in regard to RAM, it's pretty clear the performance differences between RAM in general, be it DDR3, or DDR4, 1333 Mhz or 2400 Mhz, ECC or non ECC, are negligible across the board... And though there's a lot of tests, it's still pretty fun watching them time after time failing to see any big differences in any benchmarks - because you (and Linus) are just waiting and waiting to see something, anything, but naeh, there's just not much difference. :D

https://www.youtube.com/results?search_ ... s+tech+ram

Though VRAM speeds seems to be a whole other story - if I understand it correctly, the main reason for the 1080 being faster than the 1070 is mainly in the faster VRAM. Though I might of course not understand it at all. ;)

Hmm, then again, there's this... Very surprising, though of course not very relevant for me as I use AE very little, nowadays, and don't use Premiere Pro at all.

Talking with my dad about this build and how it compares to a new setup in regard to cost I realized the cost for...

1x Fractal Design XL R2 case
1x Asus Z9PE-D16 motherboard
2x Intel E5-2670v2 CPUs
2x Hyper 212 Evo coolers
16x 8Gb ECC reg. RAM

...exactly equal the cost of...

1x Intel i7-6900K CPU(if bought new here in Sweden)

Damn, that's not a bad deal, hehe... :D

On the downside, I haven't been able to boot this thing from an m.2 (using an Asus Hyper 4x PCIe adapter) so far. I'm getting an Intel 750 400Gb PCIe SSD tomorrow, though Asus support says it's unlikely to work booting from, I found a video where someone runs one as boot disk on this motherboard - so hopefully it'll work. Though I would have preferred a cheaper Samsung 950 Pro 512Gb. I'll run one of those for current footage/assets and caching instead.

The level of sense that made is trending towards a negative number. ;)

But I agree we should probably take Tiner back to the zoo, for everyone's safety. :D

Hehe, no, Facebook is pretty horrible, probably because it's filled to the brim with people I know... ;)

I try to keep mostly on Twitter and I try to keep my tweets and interactions there about VFX, thus the people I interact with are mostly VFX artists - and then I of course run here & at OD Force.

Zoo huh... :P
You might need a bios update to be able to use the m.2 as boot?
Luckily i bought a brand spanking new 2016 overpriced motherboard so no issues for me mihi :P

Seems no one clocked the 6950X in the Cycles Benchmark. Latest Blender build is also 30% faster on CUDA due to CUDA 8 implementation.

Latest build: https://builder.blender.org/download/bl ... -win64.zip

The testfile: https://www.dropbox.com/s/6eg8a4l4lqig7 ... blend?dl=0

Under performance, to get the best speed, for CPU use 16x16 tiles, for GPU use 480x270 or 480x 540 tiles.

Post results here and/or at https://blenderartists.org/forum/showth ... pdated-BMW)

If you don't wanna register, I can post them for you. People would love to have the 6950x and the TitanX Pascal benchmarks... :)

I can do that after im done with all the transfer stuff from my old computer, god its boring :P

By the way, looks like my bios is automatically overclocking my cpu to 4ghz (multithreading). I believe the default Boost is 3,5Ghz and 4ghz on single thread. So im gonna be good with 4 for now. I got 2100 in cinebench, and its dead silent :) As long as i dont do 3dmark benching with the gpus haha sounds like a vacuum cleaner... Next up will be to get a custom water cooling loop for them gfx cards and a 4K 32" Monitor :)

Why didn't you just do an OS migration using Paragon or EaseUS on an USB stick? Windows 10 is amazingly portable - this is my first and only Windows 10 install and I migrated it at least 3 times between SSD's including one this last time, migrating it to a whole new mb/CPU setup - as described earlier in this thread... Installing Windows and the apps from scratch is torture on a level the UN is planning to ban the practice completely... ;)

Aah, ok. But you run Windows 10 on this one? If so, yeah, it's pretty darned amazing.

It's pretty funny how Microsoft managed to crap out every other Windows version, hehe, and then you have the mystery that is Windows 9. :D

Soo i did the test and i got 01:32:80. Now its only running at 3.8Ghz since Cycles uses AVX for whatever reason. I have an offset of 2 in bios so its not running to hot when running AVX applications which i never thought that i would do since its not to comon...

AVX are suppose to run alot hotter, not that blender did but when i tested a newer version of Prime95 it did :) So maybe i could get it 6-10 seconds faster if i put it to 4Ghz.

For the gpus, i didnt have any otions to use them.

Yeah, at 4 Ghz you would probably match my time at 1.16 - but one thing I have you beat is heat - I can max this thing all night on a burn test and it'll never go past 60-61 C... Even compared to running the GPU on max, the hottest thing in my box - not even kidding - seems to be the RAM. I'll probably switch the modules I have for 1600 Mhz with RAM-coolers - I should have bought those from the start, but I had 2 weeks shipping on those compared to 2 days from UK for the one's I run now... The price was basically the same.

And though it's not a huge issue, seeing the lower single thread performance I have now (compared to my 4790K) and that is an obvious bottleneck in some situations, I also decided I will update these CPUs down the line, there are 8 core E5 v2 Xeon's that run on 3.3-3.5 Ghz and turbo at 4-4.1 Ghz.

Edit:

Here's an example where I think the 6950X will kill my setup. Download this hip (link), go into the coral_growth object, on frame one, reset the purple solver, highlight the out_coral, then press play and see how long time it'll take to calculate the growth to the last frame, frame 74. It takes me 1.19m, I suspect the 6950X will be way faster.

***

As for Blender not recognizing your GPUs, that's kinda weird. You go the latest Nvidia drivers, I mean, you just have to seeing you installed them a day ago... Did you check the preferences? Last tab you got a dropdown for CUDA - though it should find them automagically. If not, friggin weird. I'll post the question in the thread, see if anyone know what's wrong.

Edit: Try this build: https://builder.blender.org/download/bl ... -win64.zip



And here's the link to the OD Force post with the hip, if the first link doesn't work. :)

Yeah it's cooler but mine isnt far off :) My hottest core in Prime95 was 70c. Rendering with vray i think the hottest was 63c. This is with my case fans being at its lowest. Idle i cant hear my computer and that is sooo nice :) cpu rendering you can here the cpu fans a tiny bit. But if i stress the gfx cards you can definitely hear them haha.

I got 1:06 on the coral_growth, so not way faster but a little bit atleast :P For the money i should have gotten 20 sec lol
