Furia jumpers

PDrill · 06 April 2020, 16:42

Got mine today, but I just can't find any info about the jumpers on it. They (mostly the RAM WAIT) have been mentioned many times also in this forum, but what do they really do and when and what for should they be used?

The other one is, like said, RAM WAIT and the options are on or off.

And the other is on the other side of the board and it has 3 pins so it has 3 options, position 1, position 2 and the jumper removed completely.

RAMWAIT - Open 1-WaitState, memory slow. Close Zero-WaitState, memory fast.
Bottom Jumper, power supply of DRAM. This setting must not be changed, otherwise the DRAM chips will be damaged.

My A600 is still on the way so I haven't been able to try it yet, but while waiting and just to be sure, is this the correct position?

I must say, sounds very strange to have a jumper which can damage the device and not have any kind of documentation or even a note printed on the PCB :-/

Why would you want to mess around with the jumpers anyway ?

When my Furia came I just plugged it in and that was it....job done ?

this is a factory setting, not user settings.

Well first of all, I like to know my stuff. Second is that I've read ~all Furia threads here and there and in some cases there has been discussion about the RAM juper so I was also looking for info what it does and when to try it. Third is that I removed the unknown jumper to look under it to see if something was printed there as is the case with the RAM jumper, and learning from here that wrong position is lethal, I wanted to be sure that I replaced it corretcly.

My A600 is still on it's way back so I haven't been able to test it, so fourth reason for my original question was that maybe it is/they are something to fiddle with in case everything doesn't go so smooth.

I - like propably most people here - am at that age that I have played with PC mainboards long before Plug & Play so testing different configurations (jumpers in this case) in case of a problem has been normal. And I'm happy to have asked this and I can make a Dymo-print next to it to remind me not to ever touch the other one even if it doesn't work.

Hope my answer satisfies your interest.

I just got my Furia back from Lotharek and im having problems getting it to work. I see that the jumper on the underside is in the opposite setting on mine. The middle and left pin is where my jumper is. Is that wrong or right?

Memory DRAM VCC 5V or 3V3, did I satisfy your curiosity? :-)
