Title: C2D MB for mining Post by: Refrumatrix on April 15, 2021, 07:29:53 AM I have a core 2 duo pc here and three gpu cards I'm trying to build for a friend but the c2d motherboard has 6pin main power connector unlike other PC mother's with 24 pin power connector so I can't use power supply in the motherboard is there any way around this?

Yellow 12V Black 0V What is the voltage on the blue wire? If 5 or 3.3 V then you can make an adapter. Or use 2 power supplies. A special power supply for this motherboard, the other power supply for graphics cards.

So it's possible to use two power supplies on such motherboard like that? I have one that's close to OP description in my store, I don't bother to use since I believe it can never work for mining, such a shame the motherboard have 4 pice slots for gpu Yellow 12V Black 0V What is the voltage on the blue wire?

And for ddr2 c2d motherboard. I have the ones with molex power connector in them, no need to use that. Corsair ax1500i is not compatible to that old motherboard so i used an old psu to power the system and an ax1500i for the gpus/risers Title: Re: C2D MB for mining Post by: FP91G on April 16, 2021, 11:09:48 AM The standard voltages on the power supply for the computer are 12, 5 and 3.3 V.

This Power Supply Sync will also turn off the controlled power supplies if you turn off your farm. I used an old motherboard on a 2-core C2Duo processor (775 socket), but it didn't work for long and I had to buy a new motherboard, processor and memory.

All my motherboards are Dell OEM and none looks like this but I understand that this is core 2duo motherboard so it could look this different since it's old skool, using power connector should work perfectly ok Title: Re: C2D MB for mining Post by: vuli1 on April 16, 2021, 07:17:20 PM Take a look this link, well, it is a HP mobo
https://superuser.com/questions/869600/what-is-the-6-pin-power-connector-on-an-hp-prodesk they had more effeicient psu that time already because they were 12V only and it looks mobo had 5V and 3.3V regulators on it. Kinda like Intel now want to make a new ATX standard ATX 12VO |
