  1. Well i would def try to downclock it! Less power it takes from pcie is better !! U covered with 225w on 6+8 pin and max 25w just to be safe! Max doesnt mean peak! Ur peaks could be up to 40-60 wat on pcie! Or much more if ur card is set to to higher values! I would use something like msi afterburner and flash it with lower values! Its really quick and u wont be disappointed in case ur psu or gpu are not bad.. If ur fans are spining on gpu it means its cooled! Overheating could be a luck of power too... or just use a powered raiser or the soldering mod!;) if u still want to experiment..
  2. Hey ! Looks like u have a nice PSU!!! I would drop 8pin pcie on one 12v lane and 6pin pcie and ur 8pin cpu to barrel on another. Any chance the card overheats ? you say it freeze after the benchmarks?! Did u tried another good quality psu ?
  3. Well ... Your card is 250W 6pin-75w + 8pin-150w = 225 so akitio give another 25-40 wats to your card and its shouldnt be a problem ... I assume its not overclocked .... I think u need at least 23amp on 12v rail ... I have no Microsoft products in my possession so can't help with windows ... I wouldn't recommend connecting anything to the akitio thunderbolt... just use another thunderbolt port if u have.. if not just for sake of clean work disconnect it till ur setup is stable and hook it back when u done.. What PSU u r using ?? What is the bios on ur Titan its not overclocked right ?? overclocking will sip more power...
  4. What card u use??? Which power connectors u have on a catrd?? why u have 2 cables connected to thunderbolt??
  5. Hi there ! After going thru 3 750ti i can tell that this card takes even 80w and 90w on setups probably more!!! Now u can get 75w max on akittio! I recomend to change the bios to 38w max . down clocking will actually help and not over clocking wich requires more power! what is the bios version u r on?? ok now i see ur bios set to 38w .. I had same card working nicely .. Computer gets hot cuz intel chip is working on thunderbolt.. Any ways looks like ur card power manegement laging some where.. I had simillar problems with slow downs on mac bfr i edited AGPM.
  6. 8pin cpu connector is 4positive ussually yellow and 4 negative ussually black! Just connect positive to center pin on any 5.5x2.5 barel connector ... Will make photos today..
  7. Yes ! 8pin cpu cable with 4pos and 4neg working fo a few days now ;)!!!
  8. Yes u can !! It will be really stable 12v output if u have it on your PSU as far a i read ! Will try it tomorrow !!!
  9. did u had molex to barel adapter ? If yes ! There must be a problem!!! Looks like tons of people do this molex to barrel adapter and suffer from not stable gpu! But from what can i see suffer mostly people who actually need 75w or so from pcie. I had original akittio power adapter , solidgear 450w and thermaltek 600w. Both 450 and 600w had barel adapter to dual molex . Zotac 750ti in bios its 38w max Evga 750ti in bios 58w max When Both of the psu with molex to barel for my surprize evga shuts down during the load ! Furmark will make it panic.. Original 60w akittio all work like a charm but i can hear the card hungry for power.. Zotac works on both setups remmeber its 38w. So i had to dig ! Just take a look at ur typical molex connector ! It has this 5v! Look at ur 8pin pcie! Does it ? Iread somewhere that this lines arent made to have a stable 12v without 5v . i guess someone can explain this ..... i remmeber working as IT and we had this workstations with like 10 hdds and i used ibm only hdd that days and i had power failures with high quality power supplys . And our gpu days we have this 8pin and 6 pin dedicated lines .. To make a story short thermaltek 8pin to barel (12v - 100w) works on both cards!! U still must have working AGPM for the card to work properly ! For my stupidity i didnt even noticed only 1x12v line on both spu's molex! single rail spu i had was giving 38w per 12v -18awg cable! so i had 2 cables would estimate 76w. I heard people pulled out 80w and more from akittio brick and even more!!! multi rail psu had one line only with one 12v estimating 50w and many molex connections ! this is why zotac 750ti 38w + 10or 15w for Akitio components worked!
  10. Ok Guys I'm here to thank you all for such a huge work you all did so we can enjoy the freedom of Egpu !!! BUT I think most of you doing such unnecessary job as soldering forgetting the most important thing power distribution on GPU comes from AGPM! If your AGPM is not configured right and most of the posts i see about AGPM are not enough ur GPU WILL NOT BE STABLE!!!!! My setup : Mac Mini (late 2012) TB1 Akittio box 450 PSU with Molex to Barel mod. Zotac 750ti. The box is closed and i had to drill like 15 holes for the airflow.. well, this setup will never work stable Unless you configure the AGPM right !!!!!!!!!!! From what i understand no Maxwell card will be stable without correct AGPM. I went thru 3 psu's with same results crashing on a load or with random gpu access (open GL or OpenCl). 3 different 750ti's ( Zotac is the most stable out there without any AGPM mods). Just to point out I'm not playing games !!!! i do some heavy video editing and graphics!!!! I need my computer stable !!! this is why i use MACS!! So after playing so much i came to the best AGPM setup and my card is stable !!! I can run fur mark for an hour or more without any crashes !!! Heaven don't touch the balls even !!! What i did was : i found the closest card to mine in Original Mac and configured it !!! I want to share it with you maybe this will help someone : <dict> <key>GFX0</key> <dict> <key>Heuristic</key> <dict> <key>ID</key> <integer>4</integer> </dict> <key>control-id</key> <integer>17</integer> </dict> <key>Vendor10deDevice1380</key> <dict> <key>BoostPState</key> <array> <integer>0</integer> <integer>1</integer> <integer>2</integer> <integer>3</integer> </array> <key>BoostTime</key> <array> <integer>2</integer> <integer>2</integer> <integer>2</integer> <integer>2</integer> </array> <key>Heuristic</key> <dict> <key>EnableEnergyPstate</key> <integer>1</integer> <key>EnergyDOWNThreshold</key> <integer>20</integer> <key>EnergyPstate</key> <integer>1</integer> <key>EnergyUPThreshold</key> <integer>40</integer> <key>EngineDOWNThreshold</key> <integer>20</integer> <key>EngineUPThreshold</key> <integer>99</integer> <key>ID</key> <integer>4</integer> <key>MemDOWNThreshold</key> <integer>15</integer> <key>MemUPThreshold</key> <integer>99</integer> <key>MinP0P1</key> <integer>1</integer> <key>MinP5</key> <integer>5</integer> <key>MinP8</key> <integer>13</integer> <key>MinVP0</key> <integer>1</integer> <key>MinVP1</key> <integer>2</integer> <key>MinVP5</key> <integer>10</integer> <key>MinVP8</key> <integer>23</integer> <key>NumOfPstates</key> <integer>14</integer> <key>NumOfVPstates</key> <integer>28</integer> <key>P0Table</key> <array> <integer>0</integer> <integer>1</integer> <integer>2</integer> <integer>3</integer> <integer>4</integer> <integer>5</integer> <integer>6</integer> <integer>7</integer> <integer>21</integer> <integer>22</integer> <integer>23</integer> <integer>24</integer> <integer>25</integer> <integer>27</integer> </array> <key>P1Table</key> <array> <integer>8</integer> <integer>9</integer> <integer>10</integer> <integer>11</integer> <integer>12</integer> <integer>13</integer> <integer>14</integer> <integer>15</integer> <integer>21</integer> <integer>22</integer> <integer>23</integer> <integer>24</integer> <integer>25</integer> <integer>27</integer> </array> </dict> <key>control-id</key> <integer>17</integer> </dict> <key>IGPU</key> <dict> <key>Heuristic</key> <dict> <key>EnableOverride</key> <integer>0</integer> <key>ID</key> <integer>2</integer> </dict> <key>control-id</key> <integer>16</integer> </dict> </dict>
