Topic: unstable speed in PCIe x1 extender (Read 3118 times)
Dont know, i'd advise looking up the PCI-E specs when messing with an expensive computer/gfx card.
nevermind, found it

In this website it say it re-routed 5 12v lines...Quote
I modified each of the four flexible PCIe extenders to re-route the five 12V lines (PCIe pins A2, A3, B1, B2, B3) to a single 16AWG stranded wire directly connected to one of the 12V outputs of the power supply.

But from this chart you can understand that there are only 4 12v lines
A2 A3 B1 B2
B3 is Reserved and not 12V ...
Soo do I also re-route him or not? thank you.
The thing i dont understand is, 1000000A is being sucked in via molex but has to exit through the PCI lane, why dont people modify the negative?

just pin 2 running to 12v in a molex connector is all you need?
Got a bunch of 1x extenders and don't want to wait to get some ones w/ molex from cablesarus
wasn't able to use my 3rd 5830 in a p5w DH. I'm sure i'll have bigger problems trying to get 3x 5830 & a 5870 running in my 939 lanparty board
Well I dont use a one with a molex. .Maybe I can modify it?
Could this be the problem?

Im getting stable speed of 441Mh/s on a 5870 using a pci-e x1 to x16 extender (the extender has a molex to get the energy from the PS directly and not from the motherboard, got it at cablesaurius).
Hello,
I have a pc with 2 5850, 1 PCI-e x16 and 1 PCI-e x 1
And I'm experiencing unstable speed on the PCI-e x1
Anyone know what could be the reason for this??
bolth of the cards are overclocked 850,900 and one is stable on 320MH/S and the second one the PCI-Ex1 is going up and down between 260 to 320...
Anyhelp will be great thank you
