basic rules for ram...

more capacity > more speed > tighter timing

imho.. just add another pair of 2x1gb ram since u are not gonna OC it (assuming u are running 400x8 for ur proc)

it always better to get back the ram of the exact model n brand to be added.... but if u really cant find it other brand ram of the same speed oso can be added actually...

ok, so let's say i would just wanna use 4 gigs of rams, and i would like to buy new ones, which configuration would be better, or wiser?

2x2gb of cl4-800mhz (same modules) or 4x1gb cl4-800mhz (same modules)

and for the mild oc of my proc (400x8), which brands of rams would suit me best?

so far i see that the corsair xms2 dhx cl4 series prices were not bad, or does any of the sifus here got any opinion or recommendations?

thanks!

well.... 2x2gb wud suit u better... afaik having more ram stresses the mobo n generate more heat....

just go for the corsair if u think the price is right for u

there are a few 2x2gb rams like team elite or crucial that is priced quite good iirc

did i post here in regards to your query? i think my post kena deleted

if ur current 2x1gb adata able to run cl4, then it's definite wise to just add-in another 2x1gb cl4-800.
that'll gives you 4x1gb cl4-800

as for the 4 sticks vs 2 sticks concerns,
the stress on mobo often relates to the difference in max. oc between them.
while you are running @stock ddr800 (1:1) , i see no problem on that.
the heat from additional 2 sticks only concerns when u oc/increase vdimm on it.
in ur case, ddr800 is stock, so no problem on that too.
_
if ur current adata only capable of cl5-800,
and you considering between buying another 4sticks on 1gb , or 2x2gb
then 2x2gb is definitely ur choice, as you are not into clocking high speed.

so if you were to going for 2x2gb, just pick the cheapest kit rated cl4-800 as u don't need high performance kit,
as although they prove to clocks quite nice on speed, but don't forget you are running 8x400.
u need no more than ddr800. (though some may argue that they can pushing the ram alone using divider/multip. , but it's generally pointless to do so.)

do note that the difference between cl5-800 vs cl4-800 , is very minimal.
so i'd actually prefer the 1st way which is just add in another 2x1gb to form total of 4gb.
but best if ur current adata able to do cl4-800, then 4x1gb is definitely the way to go.
_
as for best results on ur case "without the concern of $$$" ,
as you'r running 8x400, i'd reckon cl3-800 1:1 setup.
there are 2x1gb cl3-800 kits around (eg. kingston hyperX pc2-6400 cl3 2gb kit.)
two sets of them gives u 4x1gb cl3-800 1:1 setup.
(i don't recall any 2x2gb sticks able to do cl3-800 , as 2gb sticks doesn't have l337 chips on them.)
_

thanks for all the answers!

i just ordered myself a g.skill pi black series cl4-900 4gb kit. hopefully it will suit my needs! (i could oc my proc abit more too when i get better cooling)

my adata wasnt stable at cl4, yesterday i tested it at cl5 and it produce 1 or 2 errors too!

anyway thank you all again!

interesting answer for a guy who never tried the above and hypothesizing on answers..

truly interesting
lets see how much wrong this is..
first would be running 4x1gb sticks vs 2x2gb sticks...
no issue with current mobos and really not that much stress on the nb voltages.
4x1gb has better latencies and bandwidth..
but the con is u need to buy the same chipset...
preferabbly buy the 2 pairs the same time from the same batches..
yes ram has batches too....

second the reason for ram multipliers is to reduce the performance levels
aka 4ghz 400x10 at 800 CL3 PL6 vs 400x10 1200 CL5 performance level 5.. big difference kiddo.
google anandtech rampage formula.... and he explained it there quite well on trD;s and latencies...
so ure wrong kiddo.

the previous reviews of latencies of 800 CL4 vs 800 CL5 vs 800 CL3.. is null and void. y?? because before the introduction of p35's and thats only a few that can be named
there was no option to choose performance levels. every motherboard manufactorer sets a mem table in the bios that corresponds to a certain level.
to make the boards compaitable to all the ram manufactorers they made it very very laxed... so again sorry ure out.

third only two IC's can do 800 CL3's the elpidas and micron D9GMH.
have u even had 800 CL3's??

to the person that originally asked the question

i would say 4x1gb is a better performance
but if u already have a 2x1gb say 800 CL4.. then i'd say do a total change to a 2x2gb or 4x1gb
the cheaper option is the 2x2gb.

I have this XFX 780i mobo... I tried putting 4 stick Dorminator but when booting, it says 4 DIMM not supported? My 4 stick Dorminator tested all no problems... I swap slot and swap Dorminator using 2 DIMM slot no problem...

Use 4 DIMM slot... after boot into windows... only 2 gig is recognise... WEIRD!!???

make sure the mem remap is enabled

i'm not the one who say there's troubles running 1x4gb , it's the other one.
i'm stating there's difference in achieving max OC on ram comparing 2x1gb vs 4x1gb.
(eg. , what i saw in this forum, 2x1gb crucial 10th anni. vs adding another 2 same sticks 10th anni. )
as what u said, it could be dependant on chipset, as you don't encounter it on ur rampage x48 but what bout p35?
so what i said does exist, right?
or your'r saying current whatever chipset g33 ,p35, x48 , all no different in handling 2 vs 4 sticks ram on comparing to achieve the very same Max. OC?
Thanks for enlighten me, for what i saw.


yes, i agree.
i know there's bigg difference there, 400x10 at 800 CL3 PL6 vs 400x10 1200 CL5 PL 5
is it practical enough, running 1200 CL5 PL 5, daily usage?

let's make it more realistic for the one who ask for suggestion at above.
which 1 is easier to achieve?


No, i don't have one. I don't have money to own all the hardwares that i suggests in this forum.
So does every forumer in here, except you.

What's so difficult if you got the money?
team extreem 6400 cl3 kit
kingston hyperx LL 6400 cl3 kit
geil 6400 cl3 kit
(Doesn't works @ what's being Rated on the surface of the kit itself? , Throw it back and screws them hard.)




go into your bios,
look for options - memory hole remapping, (some may differs in terms used, eg, memory hole, memory remapping, etc.)
enable it will do the job.

okok. thanks. i did mention im Not going for extreme oc for my rig (unless of course i'v finally got the money to upgrade my cooling). plus i've already ordered a 7200 cl4 4g kit.

thanks for all the enlightments btw!
