How would 3 sticks work?

**kukri** · 11-30-2003, 01:11 AM

Right now I have 2x256. I want to upgrade to 1GB RAM. Motherboard I am going to get nf7-s has 3 slots. btw mine rite now is single channel. so the question is: How would 3 slots work? How would dual channel work? should I get one more 512 stick or only way to dual channel with 1gb would be to buy 2x512 and sell 2x256?

kthx

i wish it had 4 slots for 4x256

It is possible to run 3 sticks (2x 256, 1x 512) of RAM and still be in DUAL Channel Mode. You should know, that some of those who've tried it, find it unstable. And such a config, will adversely affect overclocking.

crap. that's teh gay..ill have to get 2x512

what about 3x256 for 768?

If you occupy all three slots with 256 modules..then one channel will have a total of 512Mb. That channel will be running in 128bit mode. The second channel will have only 256mb. That channel will be running in 64bit mode.

I'm not saying that 3x256mb (or 3x 512mb) wouldn't work. It does. But you would want to have both channels running in 128bit mode. The only way to get 128bit mode with 3 modules.. is to use 2x 256 + 1x 512 (or 2x 512 + 1x 1024). That way EACH channel will have a equal amount of memory.

Once my other stick of 512 comes in I'll be setting mine up w/ 2 256's and 1 512. Is there anything in the bios that I should change timing wise or do I just throw it in and see what happens?

All three are Buffalo CH-5's.

Thanks...

No settings in the bios to change.
'Just throw it in'

Code:

slot 1 - 512mb (channel 0)

slot 2 - 256mb (channel 1)
slot 3 - 256mb (channel 1)

From what I understand the nForce2 boards have more than
their share of problems with double sided (512Mb) modules.
That is why 256Mb single sided modules give higher FSB
speeds than the two sided variety.
This is exceptionally pronounced with my SOLTEK it seems.

With that in mind 256+256+256 might be preferable
to 256+256+512.

Well, I'm only pushing my 2500 at 205x11 so I'm hoping I'll be fine with 2, 256's and 1, 512. I'll try more FSB when I get in that mode again. I'm not a very patient person

argh..hopefully mine will go 2400mhz with nf7s 200Mhzx12

well crap..so if I am running a 256 2700 in slot #1 and a 256 2700 in slot #3, what the heck am i running...?????? And should i be better off just putting the other stick in slot 2 until i purchase a 512..the bios says it is running dual channel...ahhhh

K7N2 Delta Series 400 edition MSI nForce Chipset
Athlon xp 2500 overclocked to 11X205 (stable)
Radeon 9600 Pro 128 X8
"Generic" 256 ddr 333 2700 X 2= 512 MG
Maxtor 13 gig HD 7200

any help on Generic ram compared to brand name ram...if uping the FSB also increasing ram...my ram might be bottle neck on future overclocking..can't get it above 11X205...

spent 50$ per stick of my ram..PC Club....

it doesn't matter if there is two sticks. it matters when there is 3 and they different amount of memory.

**senorbuck** · 12-03-2003, 06:08 PM

Here's a thread regarding the same subject. Everyone there seems to have no problems running 2x256's and 1x512.

My 512 arrived today. I'll report back with results
