1,85 set at the Power Card directly

Over the last 2 weeks I soldered 9 x A/E/G-Power to TitanX cards and I wanted to give a little feedback of what 8 Pack and me experienced while benching a ton of TitanX cards. GIGABYTE GPower Initially we planed to use 4 x G-Power from GIGABYTE because you can connect the G-Power controller via USB to the system and controll the cards over software. It's easier for 4 cards than using the controller. Following my TitanX-External-Power-Guide I attached one G-Power first and applied the normal FB-Memory mod. However, using 1,75 Volt on the memory the stock VRM died. Probably just bad luck because on all other cards the mod worked without any problems. As a result I attached the G-Power V2 voltage output to the memory on the card so we can still use it. The problem is that we lost about 200 MHz on the memory moving from stock VRM to G-Power on memory. Testing the G-Power on the core we always experienced OCP at around 1800 MHz @ 1,6 Volt (all voltages down to 0,0 Volt. G-Power shut down). I first thought it was just a problem with the card itself but we had exactly the same on the 2nd card. So my conclusion about G-Power so far: + Software-Control possible - Don't use V2 at all on memory or you lose MHz. Always keep stock VRM - You will face OCP. We're already in contact with sofos and Hicookie but so far we couldn't find a solution EVGA EPower 2.0 The EVGA EPower works very well acually. We used it on 3 cards and no OCP/OVP or anything else. However, two EPower cards died at around 1,8 Volt and 2k+ MHz on the core. I guess there is no ocp and the power draw was just too much for these cards. On one card we suddenly had a spark near the front MLCC capacitors and eventually one tantal cap blew up: picture courtesy Overclocking TV So I removed the EPower and luckily the card was still alive (GPU resistance ~3 ohm). So I attached our spare EPower which worked fine for about 5 hours. Suddenly bad smell and all LEDs of the EPower shut down. So again - EPower dead. This time there was an internal short close to the mid PCIe-Connector. The ground layer of the EPower near the connector was totally burned so I guess there was an internal short somewhere (forgot to take a picture of this - sorry). So my conclusion about EVGA EPower 2.0: + The Board works very well + No OVP or OCP - However we lost 2 out of 5 which seems quite a lot. - EVGA EVbot needed ASUS Power Card The ASUS Power Card has a very nice design and great features. You can set the voltage directly on the card and you don't have to use an external controller. This is great for one card but using 4 cards with all the cables it's not that easy to access. Elmor is doing a great job with the development and if you have any feedback or problems let him know! He also recommended to me to place some additional heatsinks on the inductors and use a very strong fan for TitanX. We could run 1,8 Volt at over 2000 MHz on the GPU without any problems so the card is indeed very well designed. Just over 1,85 Volt we had OVP which I'm sure Elmor can solve with a new firmware. Conclusion about ASUS Power card: + Good design and easy to use + No controller needed (good for single/dual card) + No OCP + Firmware is easy to flash over micro USB - Difficult to use in 4 way without controller - OVP above 1,85 Volt. - Current heatsink is too high for 4-way Overall conclusion: All cards have their positive and negative aspects. In general for TitanX I would recommend EVGA EPower or the ASUS Power Card. However my personal favorite is the ASUS Power card. Simply because it's so easy to use and if there is any problem Elmor can simply send a new firmware to you.

sauber

nice work

Great stuff!

Shit If you need 5 minutes per CPU you will need ~190 hours of work without any break. Assuming you bin 3 hours per day you will need over 2 months of binning every day :D

whoops sorry. Should be public now.

Amazing event. 8 motivated guys and 7 will continue with LN2/DICE after the event. Not sure how to beat this

Great score

that might be true as well. wait what

^^^^^^this

It just makes sense to exclude vendor employees from competitions. I mean how would it look if GIGABYTE held a competition and HiCookie would beat everyone and get the prizes? And ofc you don't want an inhouse bencher from any other vendor to participate or win your competition. And early unlimited access at distributors. I'd need a real world example to belive this. Even Ian bought his Titan X and didn't get it for free from OCUK - just as an example. Ofc you have advantages but where is the difference to getting a bunnyextractionload of hardware from vendors directly? I know a lot of guys who recieve pretested GPUs and CPUs. So where's the difference?

Some Boards I don't need anymore: ASUS P5K Premium: Probably one of the best boards for old 65 nm CPUs. Works without any issues. Socket and backside partially insulated with liquid tape. Some random Celeron in the Socket as protection 70 € Biostar TPower i45 Had a hard time to get this board to run. No clue if it's partially damaged or if I'm just too stupid to handle this one. Boots fine but I can't install windows. Don't ask me why 30 € Shipping (DHL): Germany: 7€ EU: 16€ Outside EU: Depends on location. With DHL probably ~30€

Welche gpu/cpu kombination?

1.4.780 64 is the correct GUI?

Nice solution with the VDDR! Glad it worked for you.

I think it should be fine if it fits to the screenshot. It's just the damn sys-info which reads out crap

Thanks a lot guys

okay I submitted the result now. Please tell me soon if it's fine or not. Otherwise need to rebench.

I have really weird stuff with the futuremark links. is this valid? http://www.3dmark.com/3dm/6314391 Sometimes it doesnt show the CPU at all for me and sometimes detected wrong

So you Want to punish the elites because they worked harder and invested more time?

Haha. Thanks dad

Q: Do you deserve those points ??? A: Yes (general pov) Usually all the guys who recieve "special hardware" did something to recieve the card. Could be a review or just the status of an elite overclocker. However, you don't become an elite overclocker over night. You have to spend a huge amount of time and money to get there. About the team-ranking we're already working on a cool solution (should have been online months ago - blame Massman )

Thanks man!

system info 4.35 is fine I guess? Can't find 4.34 anywhere
