Title: GA 890fxa UD5 memory
Post by: CoolDude64 on October 06, 2010, 01:10:28 pm

Hi guys,

Just a quickie, I am building  new system and will be using 2 x 4GB memory sticks in dual channel, one in position1 and the other in position 3.
I am slightly confused in the manual as to how to set up dual channel. Do I set it up in the bios as ganged or unganged? The manual says
Ganged is for single dual channel, which is it single or dual?
Thanks in antisipation,

David

Hi there David,

Channels 1 & 3 will mean your RAM is running in Dual Channel Mode. Ignore the Manual, it is better if you set this to Unganged in BIOS.

Thanks a lot absic, I would have probably gone for ganged, thank you for the advice, I shall set it to unganged now in the bios.

No problem. You don't actually say what CPU you are using but Unganged is the safest way to go with the AM3's .

Sorry absic, I will be using a phenom ii x6 3.2GHz.

I have another question.
I will be installing windows 7 64 bit and would like to set all my drives to ahci, this includes the gigabyte sata 2 drives. When installing W7 do I still need a floppy drive to load the drivers on install (F6) or could I put the drivers on a flash drive and get
W7 to recognise this? On XP I had to use a floppy.

Thanks,

David

You can use a USB stick for installing the AHCI drivers and I would suggest disabling the Floppy Drive feature in BIOS if you're not going to use it.

Is there any special reason for setting up for AHCI?

Hi absic, the only reason for choosing ahci was to be able to hot swap out a drive if it fails or if I wanted to use a higher capacity drive at a later date.without powering down the system.
I had not bought a new floppy drive this time, I thought I might have to take out the one in my present system and use that to put the drivers on but as you have said I should disable the floppy drive if I am not going to use it.
Thanks for the advice about being able to use a flash drive instead.

Yes I think the day of the floppy drive has final come to an end. The ubiquitous USB drive reigns now. 8)

Running in unganged gives more stable performance and higher overclocks.  Ganged cause driver recovery with ati cards and some blue screens once in a while with lower clocks.
