  1. @kblack21 I have the EVGA 750W G2 (http://www.evga.com/Products/Product.aspx?pn=220-G2-0750-XR), which is probably overkill. I initially had an old 500W Corsair from my old desktop but I decided I was going to get a GTX 970 (MSI more specifically) and figured I wouldn't risk it even though some people said 500W should be okay. I had bought the PSU first locally at a final clearance sale, then realized that many cases that were more compact required a modular PSU. So in the end, I ended up getting a bulky case but every now and try and formulate reasons why I should 'upgrade'. Also, I just pulled out the akitio board and reconnected it and voila(!) the GPU is recognized once again! I could see how it could have gotten pulled slightly out as the circuitboard in my case is not held down firmly (probably another reason for me to go modular ). Anyways thanks! You've saved me the time and stress of replacing 'x' number of GPUs, PSUs and potentially CPUs .
  2. @kblack21 which PSU did you have? It seems like that is a common theme amidst malfunctioning eGPUs. I have a 750W but I have been looking for an excuse to switch to a modular PSU so I could put everything is a more compact case. I've never had any stuttering problems due to keeping the GPU on longer. The only time I see artifacts is when I'm trying to overclock the card
  3. Oh man, this is what I'm going through right now! I've had problems the last few weeks where after I turn on my eGPU it will throttle high then get quiet again. No biggie, but more recently when I have my eGPU connected I will get random kernel panics. It didn't happen frequently enough for me to really be too bothered by it until the other day where it disconnected entirely. I checked all the cables and the fans on the GPU still ran if I hot plugged in the eGPU after startup but it did not register the actual GPU itself. I was considering warrantying my GPU thinking that had to be the problem or getting my Mac checked out.... I'll try this tonight!
  4. @goalque Just ran the script (version 0.9.3) using [-skipdrivers] then restart and it works again . Thanks again!
  5. Alright thanks! I'll give it a try when I get home tonight and let you know how it goes. I'm assuming that it is due to the Nvidia update because I haven't updated anything else that comes to mind that should affect it. I guess I'll avoid the prompt in the future.
  6. Hey, I dunno if anyone can comment on this, but the other day I was prompted for was an update for the Nvidia graphics drivers (on OS X) and after updating my external monitor or GPU is no longer detected. Could I simply run the script again or would there be some dire repercussions from that? Otherwise would the -uninstall then re-run the script be better? Now that there is 0.9.5 out reinstalling OSX 10.10 is necessary; but does that mean like a complete wipe then backup restore? Thanks!
  7. So I took a look running a few games on the OSX side and found that unless I make my external monitor my "main monitor" it will be opening them on the internal screen running with the Intel Iris Pro. As soon as I set my external monitor to the main monitor in the displays tab "about this mac" it now has both monitors coming up as my gtx970. Unfortunately, mine does not revert back to the iGPU when I adjust settings, so I can't really comment on that :/. If you are simply trying to "turn off" the internal screen all you have to do is turn your brightness to 0 and your internal screen is off.
  8. For me I just assumed that was supposed to happen? Your internal screen would be running using Intel Iris Pro and then the external monitor would be entirely by the eGPU so as to not be losing performance due to what is going on, on your internal screen. At least, that I assumed to be happening and what happens when I am on Windows 8.1. I didn't do any benchmarks yesterday so I couldn't say for sure if running anything will it to revert to the iGPU.
  9. Just ran the script on a mid 2014 rMPB OS10.10.4 with a gtx970 and it worked like a charm! Cheers!
  10. Cool thanks! Also, I've started into looking at running the eGPU in OSX. In your guide it appears you had it working at some point but after several boots it no longer ran(?). Did you ever resolve that problem?
  11. @Dschijn I just had a question about the 90 degree riser. I unfortunately bought the wrong PCI-E riser being that it angles to the left (out of the case) instead of right (into the case). I thought I had ordered the right one but I guess I got spatially confused. Now that I am looking for a riser that angles to the right I've found that they are far less common. I have found three different ones but they differ by $50 dollars and I am unsure if they are the same or not. I was hoping if you (or anyone else) could confirm before I end up ordering another one that doesn't work. Leftward Left Angle PCI Riser Card Connector Adapter: Amazon.ca: Electronics http://www.amazon.ca/gp/product/B001PNGEBK/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=A3KZFHPRUM5A3U Aliexpress.com : Buy PCI EXPRESS X16 RISER CARD RIGHT Slot Adapter (Star Empery PT328HR) from Reliable pci express x16 nvidia suppliers on PCOLTECH(Star Empery) Technology Co.,Ltd | Alibaba Group The second one I have seen people post using but it is the most expensive ~50USD; the first and the third ones appear cheaper (both build and price) but I would probably order one of them so as long as they work. Thanks!
  12. Ahhhhh okay thanks! - - - Updated - - - Ahhhhh okay thanks, I didn't realize that. I was still under the impression that the powered riser was still the best way to go. With regards to the signal degradation it is just the powered molex riser which degrades overtime? So with what I have currently, that would mean I would eventually have to replace the powered riser? Does this also affect the integrity of the PCie board as well?
  13. @Tech Inferno Fan Is what I said in my last post entirely off? (Looking back at the Akitio forum I guess it is 25W as opposed to 75W) But from my understanding is that if you want to power a full length GPU that draws more power than the Akitio can handle, you need to have a powered riser OR solder a 12V/GND power supply to the pcie board?
  14. It should work in Windows, depending on what you are using it may or may not work in OSX. I have a running eGPU connected to my MPB using Akitio and they appear to be similar. Akitio will work in bootcamp, they don't support GPU's meaning that they won't help you implement a eGPU if you were to ask them for help about it. Check out this for more info on the Akitio: http://forum.techinferno.com/enclosures-adapters/7205-us$189-akitio-thunder2-pcie-box-16gbps-tb2.html Akitio is probably the cheapest option because you really just need the thunderbolt2 to pcie x16 board inside of it; however, you can run with a smaller GPU so as long as it fits inside the chasis and is low on power consumption. <strike>The powered riser is needed because the Akitio itself only supplies 75W when connected. Instead you use a powered riser w/ molex, this will connect to the pcie x16 end to your GPU which also connects to a PSU (via molex) and you power it by that means instead of relying on the Akitio power supply.</strike>
  15. Mac Mini features thunderbolt 2 and from what I've seen you can do the same thing with the Mac Mini as many people are implementing here with their Macbook Pros/Airs. The ViDock has it's own limitations which makes it less desirable compared to the other options but Sonnet can feature full length GPUs depending on what expansion chassis you go with. The Akitio Thunderbolt 2 is a popular choice just because it is relatively cheap and you can attach a full length GPU so as long as you have a powered riser and PSU to attach it to. This has a guy using his 2012 Mac Mini with a Sonnet III-D to power a GTX780TI.
  16. Yeah I was looking at undervolting the CPU for reasons you mentioned in your guide. Do you typically overvolt your GPU?
  17. I also noticed that you undervolt your CPU to get some performance gains as well. When you are running games do you always have a pre-set for -75mV? From what I've read undervolting can't really damage your CPU unless you undervolt it so much that you don't have enough power going to your CPU for it to run, then it will just shut off (?).
  18. Also, will you get lower clock speeds on the eGPU compared to desktop GPUs? I tried OC'ing a bit and used two internet references to find the maximum I could OC my card but I get artifacts when I'm running 3DMark Firestrike and I haven't reached the same core clock/ memory they did. The hottest the GPU gets is 61 degrees.
  19. This is what I got for Unigine Valley, no OC:
  20. Thanks @Dschijn, I hadn't looked far enough ahead to realize what I needed to get everything in the enclosure. I'm sure I had read the 90 degree riser but I had no idea why until I realized the powered molex riser would not bend enough to fit. For now I have the GPU sitting on its back inside the case and the PCI-e board is attached outside of the case. But I have been running some benchmarks and I don't know if mine seem a bit low for a 970.... In your old guide did you already overclock when you ran your benchmarks? For 3DMark Firestrike I only got a 8514. For Unigine Heaven 4.0: And if ASIC scores mean anything (probably not) I have a 68.8%.
  21. @Dschijn Hey so I ended up going with a MSI 970 just because there is a local store that sells them nearby and if I did have any problems with coil whine I could go return it to them directly. Anyway, it all works (thankfully) and I am putting it inside of the Cooler Master Elite 130 enclosure, and just realized I need a PCI-E 90 degree adapter. I've already ordered one but was wondering if there were any other adjustments/ parts needed to fit the GPU inside the case? I've seen some people put plastic bases on the bottom interior of the case for whatever reason and was wondering if you (or anyone else) did the same? Thanks!
  22. Wops, yes it is 2x6 pin to 1x8pin. I thought you meant that I needed to use the 6-pin PCIe to power the fans for the Cooler Master Elite 130. 1. Yes I am 100% sure it is from the GPU just because everything is so spread out. Right now, I have my PSU sitting on a stand next to the desk and my GPU on my desk it is very clear that the noise is from the GPU and not the PSU. 2. Seriously...?! Now I'm wondering if I just have have a card with loose capacitors... could you link the website to the german comparison? I can see how well google translate works. The website linked by Nando said: "In idle, the fans on all six cards are at a standstill. Seeing as we can't register coil-whine, we note the lowest possible value our professional sound meter can measure: 17 dB(A). Under load the MSI card is clearly the quietest of them all: we measure an average of 27,5 dB(A) which is virtually inaudible. The Gigabyte card is about as silent though, at 30.4 dB(A). ASUS trails and procudes 36.5 dB(A), followed by the Zotac and Inno3D cards which produce slightly more noise. The EVGA card is the only noisy card with 53.8 dB(A) at 10 centimeters, which is too much for a GTX 960 in our opinion." They say they "can't register coil whine", and I don't know if they mean below a certain decibel that they cannot register coil whine OR that their equipment cannot pick up the frequency of coil whine at all meaning that they are measuring the sound made by the fans. If the german website mentions that they can test coil whine, I might have better luck going with a RMA with EVGA as opposed to NCIX.
  23. Do you recall how many 6/8-pin PCIe power connectors you needed for the fans? My PSU only has one 6-pin PCIe then the GTX960 card came with a 6 to 8 pin cable adaptor that splits the 6 into two 8s. Ahhh okay that makes sense. I had read around on some forum where someone said that the internal GPU was disabled but I thought that sounded odd especially when you are booting up your CPU running the internal GPU first. From listening to it yesterday it is quite bad. I know that all cards have some coil whine but I think even if I enclosed my eGPU and put it under my desk I would still hear the whining. It actually might be as bad as the video I linked. I was trying this on Witcher 2 and it would be the most noticeable once you got into the game, although in the game menu at ~130-140 it was still there (just less annoying). On high settings ~50-60 fps it was bad and V-sync was on. Turning off V-sync makes the whine way, way worse. I have the benq xl2411z monitor and I can get 144hz refresh rates with the monitor which is nice but is probably contributing to the coil whine. I am going to try to RMA the card and switch it for a Gigabyte GTX960 G1 that Nando4 pointed out, as it is supposed to be one of the quieter 960 GPUs. I just hope that I can RMA my card from NCIX.com because it has been almost a month since I ordered the card because I was waiting for other components to come in before I realized this.
  24. Oh man! Well that is super disappointing... I keep reopening intensive games to determine whether or not I can stand the coil whine... I don't think I can.... my initial reason for going with EVGA is because it has worked in other cases of eGPUs, specifically squink's post mentions how EVGA is good because it will work with optimus out of the box. If I were to go with a Gigabyte Gaming GTX960 card, would there be any downsides aside from having to manually download Optimus for the internal MBP display?
  25. Hey Nando4, I had seen that link yesterday but I wasn't sure what to make of it because there is no EVGA GTX960 card being tested for noise (unless one of the cards is synonymous to it). So I wouldn't be sure if I exchanged my current GPU for the Gigabyte GTX960 that I would necessarily be getting less/more/negligible coil whine.
