PC Peripherals any problem with 3GB RAM ?

[iosoft]

Hi

This is my RiG.

As you can see, it already have 2 x 1GB PC3200 RAMs. Total 2GB Dual Channel.
Will there be any problem if I make it 3GB setup ? (3 x 1GB PC3200 RAMs)
all same brand, chip, timings.

Yes, I know that I will loose Dual Channel, but what about stability ?

 

[Anish]

^ Nope, it wont affect stability at all, but loosing Dual Channel on that 4200+ will slow down your system more than the extra 1GB of main memory.

np wid stability...even me havin 3 gb the only problem is it will increase ur pc's performance :tongue: :rofl:

increase or decrease?

the rams run a lot slower without dual channel, it will nullify the advantage of more ram becuz of the reduced speed.

you may only see some difference in apps tht use more than 2gb ram cuz windows wont have to use 2 much of pagefiles. other than that there wont be much difference.. it will be a little slower in general.

2Gb of it will still be in dual channel, IIRC.

the additional 1GB will run in Sc mode.

You can have both dual channel and 3Gb, you need 2x1Gb and 2x512 sticks.

are u sure.....i may need it..as i run vpc a lot..and a virtual network inside it..

 

[cranky]

yup absolutely fine. same rules as for regular DC apply, it'll run at the speed of the slowest stick.

Lotsa FUD around here.. why would it be slower? On S939, the only difference, besides SC vs. DC, is that the command rate will drop from 1T to 2T.

cfEclipse has run many benchmarks on his site, EclipseOC | Home , showing that there isn't much difference between 2GB and 3GB speeds at all.

even i have a query regarding this.

i have 3*1gb ram sticks at 6667mhz. two are similar sticks and one is different. shud i remove the different brand stick?? or will i b still able to run dual channel mode wid 2 similar sticks and single channel wid different brand stick

 

[iosoft]

^ I had 4 x 512mb DDR400 ram setup in which 3 was Transcend and one Local.
They ware all same timings.

Everything ran fine but, Counter Strike:Source (updated version) always crashed.
So, you should change it to same brand and timings.

But I read in an Intel whitepaper that 3 sticks can also i run in dual channel. I clearly remember...I will post the link soon

will highly appreciate any help

When i first assembled a rig, i was not using the 2x1GB ram in dual channel for about 2 months. Then someone saw my rig in rig gallery and told me about it. I changed the ram slot and frankly, i didnt find ANY difference at all. So, i condemn the "fact" that running memory in dual channel makes a noticeable difference

:rofl: ram speed has nothing to do with dual channel mode.

though your second para is correct,OP would see no real benefits unless he really needs those gigs of memory.

as for stability,intel NB do seem to have stability issues with more ram sticks,haven't heard much on AMD systems.and if you haven't overclocked your system,i think it would be fine.

ram speed has nothing to do with dual channel mode.

yup ! ram speed doesnt depends but data flowing speed does.. dual channel provide wider data path for dataflow...single channel has 64 bit data path.....and dual channel array make it to 128 bit....whcih enable ram sticks to red and write data simultaneously.... .now u can feel the differance...............

i also doubt that if some one has three same stick .....and then he put it on mobo...and get 2 stick in dual channel an 1 in single channel...these is i think not possible coz single stich will bottle neck it..
u have to have 2x1gb+2x512 mb for 3 gb dual channel..
...some one correct me...

system respond better....try to multitask......running a single app..and saying dual channel isnt effective is not a good idea...

Go this link...Shows how to use 3 ram modules in dual channel...
Still looking for the whitepaper(was busy weekends )

Raj, I'm not asking I'm telling. When you put in 3GB stick the system will run a part of the memory in Single and a part of the memory in Dual channel.

Old hat.

We've had Dual channel since 2003, the days of the Athlon XP and the nForce2 chipset. I ran dual channel memory when a lot of peeps here were still wearing little shorts.

A simple Google search will tell you all you need to know. Not that posting your knowledge is a problem, but no one bothers to do their research these days (not directed at raj).

A simple search will also show that DC only benefits memory-intensive apps such as raytracing and Maya. Benefits in regular applications OR multitasking are mostly under 10%. All this is documented and available all over the internet.

Here, for example, is a search result from Google (Google) with the search term 'Dual channel memory benefits': dual channel memory faq - Google Search

And here is one for '3GB RAM':

Have fun.

omg frm wen did ram speed started going hand in hand wid SC or DC :rofl:
i guess he just wanted 2 post n most imp cross me :cool2: :tongue:
but 3gb will surely increase da performance atleast it has increased mine

Now lets lay the matter to rest. I've used 2 GB, upgraded to 3 GB, and it was faster. Dual channel will not make a huge difference unless you're on slower 266 MHz memory. At 400 MHz the more the memory the better, dual channel will benefit benchies not real life performance.

If you could however go with 512x2. you'll get 3 GB all the same, but with dual channel. I haven't seen your mobo though, nor the PC specs. Do you have 4 DIMMs? If so, then this is the better way out...
