[nF4 Ultra-D] Problems with 4th RAM slot

[Imrahil]

Hello,
I have the config in sign, now I'm trying the RAM modules one per time, using Goldmemory. The problem is: the orange slot closer to the socket, seems to not work when is the only to have a bank of RAM installed. The PC doesn't boot. If I insert another bank, the PC boot, but I have problems of stability @ 2,5-3-3-5 @ only 280MHz... If i put a bank in the other orange slot, the RAM is stable after a pass of GM (i have not time to make 3-4 passes, but with two modules, the program fails after few minutes). If i put the modules in yellow slots, the PC doesn't boot also. What can I do?
Thank you in advice and sorry for my bad english.

No clue on what memory you have ... but 'only' 280Mhz @ 2.5-3-3-5 aint bad at all :)

Not sure I follow you, but here's some info:

1 stick of RAM:

Slot 1 (yellow farthest from CPU)
Slot 2 (Orange slot farthest from CPU)

Using any other slots with only 1 stick, computer won't boot. This is board design

2 sticks of RAM

Slot 1 & 3 (Both yellow
Slot 2 & 4 (Both Orange)

If you mix RAM slots using 2 sticks, you will be running in single channel mode

4 sticks of RAM
Set CPC (in Genie BIOS) to disabled = 2T timing.

If this didn't answer the question, post back

Ok, thank you. But I don't undestand why if I use one stick of RAM i'm able to use certain timings... if i use both, i cannot.

Sounds like you need to play with timings.

Take a look thru the G SKILL (http://www.xtremesystems.org/forums/forumdisplay.php?f=192) forums for other people running your RAM and their settings

Nothing to do :(
