I do not recommend ASUS motherboards, warranty work fatal if you have a fault or problem, at least in its division workstation and server motherboard. I myself have had an ASUS Z10PE-D8WS, problems with SATA controller (Windows 7 and Windows 10) did not know how to solve the problem and merely not give me solutions and tell me that they would try to seek a solution by driver, every message exchanged took 3 days, the company located in the Czech republic for all Europe (for the workstation server division), only give service in English (if you speak fluidly perfect), if you want to do it by phone you have to call up there and a lot of problems more, I pass supermicro and no comparison. I'm not a supporter of liquid cooling pre assembled, I work with NOCTUA and temperatures are virtually the same and do not have the problems it can create one liquid.

Sorry for my bad English.

Sorry Juraj was working. As I said on the processors, the price is with VAT, customs 50 euros. So far it is trusted the person selling me these processors, memory modules, I bought several processors and I have been in contact with many others, I know a company that has even bought 13 of these processors. I have not had any problems so far in 2 or 3 days I have them at home without problems and gives me personal guarantee of six months (not sure if this makes it to all persons I suppose that). Processors are ES versions but have not so far had no problems whatsoever and the people I know either, temperatures, voltages are correct benchmark took with them about 6 months working daily and well. I am waiting for me to get the motherboard and power supply to mount, if you want to post them here on their operation or if you have questions we can do tests.

Nekrobul have not been tested with another rendering engine mount but next week if you want to do tests, the question is because I did not know if it was right time gain per core.

Thanks to all.

Thanks Juraj, then will go forward with the purchase of the motherboard Asus Z10PE-D8 WS, after what I was hearing here doubted if they would not give either the xeon based on dual motherboard a so wondered. The truth is that the processors left me very cheap 2,100 euros two (I have a contact in Costa Rica processors happens to me, you already have the new 24-core xeon ... crazy). I started a thread a few months ago we talked about this Juraj but will not remember, you told me that when she was put an assembled all the results, well now when I get all the will detail, promised.

I did not understand very well the explanation of Ondra, that was what he meant.

Thank you very much for your time.

forgive Ondra, me lose a little technicalities and do not quite understand the point you've made, it's better to take full power of the Xeon 2699, put them on separate motherboards or in a dual motherboard ?? (I have to ask the board questions and now I come)

Thank you very much to you both for the help.

Maybe better idea to put each xeon separately in different motherboards to get more power of each ?? I doubt give their full potential in a dual motherboard.

And working on a dual motherboard this two xeons scalability will be proportional? not if I'm wrong but seeing this does not seem worthwhile or perhaps better put Xeones working on two motherboards as perhaps render node ??

If Juraj, you're right I explained wrong. I'm talking about a single processor  with 18 cores, though I have not installed the two processors in the dual plate, these tests are in an X99 board from another team. I'm comparing the same processor but with different active cores in the corona render settings.
I am using corona render 1.3.

If I understand correctly what you say Juraj, this 18-core Xeon 2.3 Ghz give a total computing power of 4.1 and my other workstation i7 5960x 3 GHz with 8 cores give a total of 2.4 is nearly double power, but this translates into half time ?? I could not even testing but makes so that everyone knows. If I put the two Xeon dual plate up out party power is better to have them both or separately?

Thank you very much and sorry I'm a little green in some things.

Hello everyone, I'm doing a test with this great render engine but one thing puzzles me a lot, doing test render with the xeon 2699v3 (18 cores 36 threads) when using 20 cores the same scene same settings time is 15 min, with 36 cores 19 minutes, is normal so little difference ???? I have two procesors like this such dual mount plate, but the scalability seems bad, I did not like the height of the processors that are ...they work best in each separate network processors or dual mode ??

5 Cores: 1h 28 min.
8 cores: 54 min.
10 cores:45 min.
12 cores: 38 min.
16 cores: 29min.
36 : 19 min.

Greetings and sorry for my bad English.

Juraj Thanks for your time, to end the announcement was a lie and call amazon and the announcement was wrong, its price was 2000 dollars, in the end found a seller on ebay and sold E5 2699 v3 18 cores, new for 1500 dollars each and I bought two, made me a discount and I have taken both for 2800 dollars, I arrived today, I talked to him on skype and all very seriously, has given me a guarantee with and if something happens to me processor change them by others.
When I arrive tomorrow to give my evidence makes recension and seller.

Juraj thank you very much, greetings.

Hello Juraj, thank you very much for your answer, I tried via amazon to contact the seller but still has not answered, I imagine that the product is new because it says nothing but what surprises me is that in especificicaciones product says

Compatibility: HP DL380
Is not this a bit weird? not if it is incompatible with other motherboards ... I'm a little lost because not answer my messages

Hardware / New render node with Xeon E5 2650L

« on: 2015-07-29, 13:44:44 »

Hello, is my first post here to ask you for advice, I want to ride a node to render and I have a workstation i7 5960X, I have seen this option that I found interesting by price and consumption have read several reviews and gives a great punctuation in CINEBENCH 2433, the price is really competitive (865 dollar) but in the amazon sale announcement appears as HP Intel Xeon E5-2650L v3, there is a problem because it is HP ?? You know if there is a problem by asking Spain from amazon?
I thought in 2640 v3 but multi-thread performance result is worse and consume more and more expensive.

[Max] I need help! / Color temperature is not correct to real world?

« on: 2015-07-05, 17:46:58 »

Sorry for my bad English, I have a problem, until now have used V-ray for my work, but I started using Corona render and I feel fantastic but there are still things to polish but it seems very powerful. My problem is this, in V-ray by placing lights and cameras I use color temperature to recreate real scenes photographic (I come from the use of live camera and apply knowledge) but the color temperature does not meet the as if reality did in V-ray, for example a temperature of 5500 kelvin is cold but represent Corona render results in a warm light, so it is difficult to stick to reality and throw a photorealistic render. It is my problem or need to check the temperature of color? temperatures are not real.

Thank You.
