Bizhub C650 display won't come up. HELP!

Re: Bizhub C650 display won't come up. HELP!

OK, sounds like the bad ram has shifted to bank 1 now.

bank 1 will be the middle slot, though it should be printed on the board.

The ram is nothing special, just make sure you get an exact match, if 1 has died the other is sure to follow soon so i would replace both anyway.

Never touch a KM intimately without wearing a ground strap. Ram is no exception and is extremely ESD sensitive.

Thanks & we have a rubber mat to we can stand on as well. Do we put a ground wire from us to the machine?

if the machine is grounded, then yes, wear the anti static ground strap connected to the machine - thats what i do.

We could only find a one gig stick of ram & installed it into the middle slot. The 650 only allows for
1 gig total ram & it had two sticks of 512. It won't come up with the one gig stick in the middle slot, so
do we have to find two 512 sticks? No one seems to carry them.
Thanks again. We have a C500, so would it have the old style ram we could take out of it & put in the 650?

Re: Bizhub C650 display won't come up. HELP!

you MUST use 2x 512mb sticks.


If you cant find them, you will have to get them from KM. (prepare to be shocked at the cost)

We have a C500 that's unplugged. Does it have the same ram as the C650? We're also calling Tiger Direct to see if
their reg DDR ram matches our KM stick. Sure wish you lived closer to Reno! We need a local tech to service our
machines. Thanks again for helping us newbies.

Re: Bizhub C650 display won't come up. HELP!

We got new ram that's supposed to be a correct match & put the 2 sticks of 512 in, but no display. The fan & green light
are on & the red light in the back blinks, but no boot up. We left the sub power switch on & only turned off the main
power when installing the ram. Is there a turn on sequence with the power switches we should've done?
Thanks.

Doubt very much there is a switch on/off sequence..

Are you 100% the RAMs are the same!!! I used once a set from crucial and it did not work for me, then tried the ones from memory experts and actually talking to the guy he actually assured me of what I need and when arrived it was working without any problems!

Do you have another machine you can take good RAM's from? That is the fastest way to find out!

Wonder if your NV RAM gave up..maybe NV RAM recovery may help. but I would defo try another RAM's first!

We had locked NV RAM on c220 and it was nightmare to figure out ..had similar symptoms !! Had to sent later the c220 NV RAM back to manufacturer!

Good Luck!!

Thanks again & being novices, we didn't know you're supposed to unplug them machine before installing the ram? The 650 power was off, so could that have damaged the new ram? Will the ram from our c500 interchange with the 650?

Re: Bizhub C650 display won't come up. HELP!

sounds like the machine doesn't like the ram youve aquired.

I've only ever used the stuff KM provides and it works first time every time.

Do you think the C500 ram will interchange? I could try that. We bought a 1 gig stick of new ram (not KM brand)
& the hour glass came up, but the machine didn't boot.

I've never worked on a C500 so i know nothing about them, sorry.

surely someone on here can sell you some correct memory ?

Re: Bizhub C650 display won't come up. HELP!

Give them a ring and tell them you need 512 MB x2 memory for BH C650..they will be more than happy to help you and are cheaper than you think!
