  1. I was able to get my old 970 GTX to work with the 1080 Ti by using an external power supply. I could feel the heat as soon as I started rendering a test scene. I had to take out the two hard drives just above the second card because there was only a very slight gap (about 2mm) between the top of the card and the drives. Add the fact that I lost the convenience of upgrading the NVidia drivers by removing my old GT 120 (and loosing two hard drives), made this too inconvenient with the speed that I gained. I would hate to be Icarus (from the Greek tragedy) by flying too close to the sun and melting the wax, or in this case, melting my computer. Having the one 1080 Ti is incredibly fast and I will stay with the one card. As a matter of fact, Geekbench scores I ran on my computers showed the 1080 TI 2.5 time faster than my D700 graphics in OpenCL scores (additionally, I now have CUDA.) Hopefully this will help others. Bottom line: I feel comfortable with what I have until Apple releases a real Mac Pro. Mark
  2. I may have time this weekend to put in my old NVidia 970 since we have a three day weekend I'm off work tomorrow, ya! Going to mass in the morning to celebrate our veterans and then go with my dad to a gun range (he's an old Marine.) After that, the rest of the day is free. No side project, no work, and the house is clean. I am so excited about having nothing scheduled!!! I looked at the iMac Pro, and no NVidia support is a showstopper for me. And I cannot imagine how much an 18-core version will cost. I also understand that Geekbench scores are popping up of the new iMac Pro. While fast, the numbers didn't make sense to a lot of people. It turns out that Apple may have dialed back the speed on it. The only reason for this is limiting the amount of heat. Sure, it looks nice, but that is not what we want. We need speed. I'm still holding out for hope that the new Mac Pro will be a serious computer. But Apple cant go nuts pricing it. I have NO problem spending more for an Apple, but I will not spend $10,000 on a computer. Well, that's if I want to stay married! I'll be interested to hear what you finally end up doing. Mark
  3. You are welcome! Those are all good questions. First, a 4-core and 6-core only have one CPU socket. And you need a different processor. Your next question would be more difficult to answer. For me, it was a no brainer because I already had the 8-core 2009 so my financial investment was small. Having said that, getting a computer that is already to go is nice, if the price is something you are comfortable with. The price you list seems fair, I did a quick search and what I found was similar. A great place that I purchase Mac stuff from is OWC (macsales.com) and they list a similar computer for around the same price. I'll answer a couple of question at the same time. First, the Mac Pro can, kind off, handle multiple GPUs. You noticed that the computer lists a 120, but look below it and you will see the 1080Ti. I left the old original GPU in for two reasons. First, I run my monitors off of that one and have nothing plugged into the 1080Ti. This frees up the entire 1080Ti for rendering and does not have to redirect processing power to drive the monitors. The second reason is that I used a stock 1080Ti that has not been flashed to work with a Mac. A non-flashed card works perfectly, but with one catch: when Apple pushes an update to the OS, the screen does not work until I update the NVidia drivers. Pretty hard to update the drivers when you can't see anything! There are two solutions to this. First I could remote into the computer from another computer and update the drivers. The option I chose was to leave the original card in there so I can update the drivers. This gave me the added benefit of freeing up the 1080Ti for rendering. The other part of your question is using two high end GPUs for rendering. I think so, but with issues. First, the lower two slots on the Mac Pro are x16. Since the card is so big, I need to plug in the second card in an x4, slowing down the process slightly. No big deal. The other concern is power. the Mac Pro has a massive 960 watt power supply. Unfortunately, it does not supply all that massive power to the GPU plugs. So I would have to tap into the SATA power. But the SATA power only supplies about 50 watts each and I need about 75 watts each. Might work, but not sure. This won't stop me from trying. What I will try next is to put a second computer power supple next to the Mac Pro and short out two pins so it stays on. Then use that to feed a second card. If it all works, I will then attempt to rewire that Mac Pro to draw power from the DVD drive and two hard drives. So I think I can get two high end cards to work. Since they are not flashed cards, I will have to remote in to update drivers in the future. I sure hope the new modular Mac Pro supports NVidia! Hope this helps. It's great to see people out there still using Macs for high end 3D. This should be evidence to Apple to provide us with something Pro. Mark
  4. One more thing, just incase you were interested. I attached the Cinebench score for the 2009 Mac Pro. Mark
  5. You need to be aware of one problem with an eGPU. If you upgraded your 2013 Mac Pro to High Sierra, it will not work. This only works with Sierra. Apple says that eGPU support will be added sometime next year for High Sierra. I strongly agree with @TeamZissou that Apple has ignored real pro users. They somehow think a pro user is some kid with a backpack and skateboard needing a laptop. Last May, I was about to jump ship and build a Windows box, but was a difficult decision because OS X is so good. Then they announced a future "modular Mac Pro", whatever that is. So I didn't switch to Windows in hope of something for a real pro. But I needed to do something now which is why I upgraded my 2009 Mac Pro. It is now working out so well, that I now moved my 2013 Mac Pro to a secondary roll and mostly use the 2009. This should hold me over util they, hopefully, announce a real computer. Mark Mark
  6. Hi TeamZissou, yes, I used a pair of X5690s. It is easy to do, but you need to use common sense. First, you MUST upgrade the firmware if you have a 2009. Nothing will work if you do not! Once you upgrade, the following is the same for a 2010 and 2012. And for anyone else that is reading this, you must have an 8-core. If you are upgrading a 4-core, you need a different chip. I’m not sure of your technical experience so I will go into detail. If you are experienced, then I apologize for going into such detail! I first pulled out the CPU daughter board and placed it on my kitchen island. A static free area is obviously important. I then grounded myself by touching a screw on an outlet plate, since I know my house wiring is properly grounded. I used a long 3mm hex allen key wrench to loosen the four allen screws on each heatsink. Each heatsink is different so don’t mix them up. The allen screws are spring held so they don’t come off. When I heard a click, I knew that I had it loose enough. I then pulled the heatsink up. The old CPU was still stuck to the heat sink which I just twisted off. I then dropped in the new CPU as is recommended by Apple because even the smallest piece of dirt will fry everything! Next, I cleaned the heatsink with a rag and isopropyl alcohol. My next step was important and some care should be taken. Since the new processors are 2mm thicker, I was raising the heatsink up which meant that the power connector needed to be lowered. So I pushed the power connecter back through the hole and then used a screwdriver to pry the glued power cable loose. It was more difficult than you might think, but needs to be done. I used wire cutters to trim all the plastic tabs off of both sides of the connector except for the one in the middle. Next I trimmed them flat with a razor-blade. Finally, I fed the connector back through the hole and pulled it out a little. This gave me enough cable to make a secure connection once the CPU heatsinks were reinstalled 2mm higher than before. I wish I took a picture of this because it would make it easier to understand. But when you have it apart it should make sense. There are some videos on Youtube, but most were kind of weird. If you noticed on the bottom of the heatsink, there is a long thermal strip. I left that on, but added another one the same size over the heat sensors on the daughterboard. I cut it out of a thermal pad that was 2mm thick. Note that each CPU heatsink has a different length. I placed three 0.8mm thick brass washer (if I remember they were M4) on each post for the heatsink screws. While I needed to raise the heatsink 2mm, 2.4mm worked out perfectly. I then applied a thin line of thermal past to the new CPU. Make sure you DO NOT get any on the pins! Next I brought the heatsink into position and plugged in the power connector for the heatsink fan, then placed the heatsink in its proper position. Press down gently in the middle of the four screw holes. Now the most important part. If done wrong, you will be spending the next few hours on eBay looking for a new daughter board! Very carefully, tighten the screws in a pattern like you are putting a wheel on a car. About a half turn on one, then a half turn on the one across from it. Do not tighten in a circular pattern because you want the heatsink to be tightened evenly. I kept going around for half turns until about three and a half turns for each screw. If you over tighten, this will begin your eBay search. Repeat the same steps on the other CPU. Now, put the daughter board back in and boot up. One of several things will happen. First, it should boot up. However, if you hear a CPU fan running at full speed, then one CPU is bad. If not, go to System Information and click the memory tab on the top. If all your memory shows up, you are done! However, if some of your memory is missing, shut the computer down, pull out the tray, and tighten the the heatsink screws about a quarter of a turn on the CPU that has the missing memory. Put the daughter board back in and try again. Repeat until all your memory works. I strongly encourage you doing it this way because you can always tighten, but once you over tighten the heatsink screws, you are toast. As they say, you can’t put the toothpaste back in the tube at that point. Another note, if this was a 2009, you can now use faster memory but you have to reset the PRAM. I didn’t upgrade the memory because the return on investment wasn’t worth it for me. A final word of caution: the heatsinks are sharp. Be careful when handling them. Good luck! Mark
  7. I have both a 2013 Mac Pro and an early 2009 Mac Pro. I wanted to replace my Nvidia 970 GTX in my 2009 with a new 1080 Ti, but sadly Nvidia only makes the Pascal drivers available for Sierra and High Sierra, which Apple does not make available for the early 2009 Mac Pro. After some research, I found out that Apple released a firmware update for the 2010 Mac Pro, which would obviously not install on the 2009. But I found a way to install this on my 2009, and was able to install High Sierra, without ANY issues. I then purchased the 1080 Ti and installed the NVidia drivers. Octane works great. I also installed Redshift and Cycles 4D and both work perfectly. I even went a step further. Since the firmware is a 2010 (but the computer still says 2009 Mac Pro) I purchased two 3.46 6-core processors on eBay for $120 each. After some work (razor blades, washers, and some modifications) I now have a 3.46 12-core 2009 Mac Pro. A used 2009 8-core Mac Pro sells for about $650, $240 more if you want a high end 12-core computer, and about $750 for a 1080 Ti Nvidia GPU. Not too bad at under $1,700. I attached a video showing the finished product. Let me know if anyone wants to try this and I can help with the detailed steps to upgrade the firmware (not needed if you are starting with a 2010 or 2012 Mac Pro), installing new CPUs that have the lids (cheaper and more available than the lidless used in old Mac Pros, and how I installed the Nvida GPU.

  8. This isn't really a WIP, nor a final product. I have been thinking about doing a short animation, but had two challenges to over come. First is learning to animate characters, the second is to get the renders to complete in some feasible time. This was done on my old Mac Pro 2009 that now has a 1080Ti and two new 3.46 hex processors. This was rendered at 1080 and took only 1 hour and 25 minutes to render ten seconds of video. While the time is now in the acceptable range, I can spend time learning character animation. The character was something I created in DAZ and sent, with great pain, to Mixamo, and brought back into C4D for some adjustments (still messed up.) I honestly cannot remember where I got the city scene from, but it is VERY large. I was able to get the materials to work in Redshift. I like Redshift. Mark
  9. PUBG WIP Alternative

    That is VERY good. Not only are the shaders good, I love the lighting in the first one. The lighting, along with the atmosphere, does an excellent job at setting the mood. May I ask which render you used? Mark
  10. Mountains at Dawn

    I'll start saying that my style is very limited reflections. My longtime hobby has been nature photography which, at times, includes landscapes. Landscapes as well as your image is a complex set of independent and discrete objects and colors, coming together to form one perfect image. Reflections will draw the eye to the reflected object, and you will no longer consider the image as one. The reflection because the focus. I know you are a musician, so I'll give an example. Think of a symphony with 50 to 100 musicians all playing their own instrument. But it all comes together as one perfect composition. You close your eyes and all you hear is one, not many. Now, with your eyes closed, imagine one of the symbol players starts to get out of sync, or even breaks into a symbol solo drowning out the rest of the orchestra. All you are focusing on is the symbols. The symbols are like reflections: very limited and subtle, but plays a part. I'll finish with how I started: this is my style to limit reflections. I like the image as it is. Mark
  11. Emperor Royal Guard Helm

    My nine year old daughter and I already have our tickets for December 15. It is entirely possible that this day will provide more helmets for you! Nice work. Mark
  12. Mountains at Dawn

    Wow, this is amazing. The colors are incredible. Looks like something Apple would use for their wallpaper on a new version of OS X! But I have to say one thing... considering that you are Mr. anti-triangles, this looks suspiciously like one giant triangle! I guess that you do not totally hate ALL triangles. Great work! Mark
  13. Animation project

    Those area great. Ten years!! That's funny because I have been toying with a project for the past three years. It seems like when I start I get some things done and either get stuck, or life gets in the way. Then I go back to it armed with new things I learned, get farter, then get stuck or life happens again. Good luck! Mark
  14. My grandpa loved baseball and had a lot of old-time sayings. For example, if a player could not hit a ball he would often say, "He couldn't hit a bear in the ass with a banjo." I was watching baseball with my dad and uncle, both in their 80s, and they used a lot of grandpa's old saying last week when our team did poorly. My uncle asked if I could do a video of some of grandpa's old sayings. At first I thought that this would be too much, but gave a try. I have never tried character animation, but something I wanted to learn. This first version is just the beginning, a lot more to do. But it was enough too make my dad and uncle laugh. Future versions will have the man walking up to a bear, some facial expressions, and then walking away. This was also my first attempt at using Cycles4D. I used Fuse, Daz3D, and Mixamo. I still need to add fur, a better background, and more trees. Rendered on a modified 2009 Mac Pro using a NVidia 1080ti with CUDA. I have a trashcan Mac with D700 graphics, but was taking way too long with OpenCL. Mark
  15. Looks like you have the latest CUDA drivers, this is my screenshot... But I noticed that I have a newer GPU driver. However, I think you should be OK. Good Luck! Mark
