I am newbie here asking stupid question.

i plans to buy 2pcs of 1g (pc3200)kingston ram for upgrade.
can i still use my existing samsung 2 pcs 256 ram (pc3200) for the remaning slots. I am runing at single channel or dual?

My mb is Asus P4800-E Deluxe
Thanks

dump (sell) your 2x256MB PC3200 and get extra money from that...IMO, 2x1GB of RAM is enough...that's it...

AFAIK, you would not be able to run dual channel as the 4 piece are not of the same size..You will run dual channel if its 2 * 1G (if the ram is able to).The suggestion like what sniper69 said is the way to go..

noob here.
I use DDR2 533 dual channel and P4 630 3.0G 800FSB

Q1. I hear FSB and ram frequency better in same frequency, so do i need to set my 533mhz to 400mhz??
IF set to 400mhz, it will slow down the performance of CPU?

Q2. 4-4-4-12 or 3-3-3-9 is faster and best for performance?

how to claim warranty for the lifetime warranty memory stick from apacer?the shop that sold me the ram already closed shop and i email apacer but there's no reply from them..anyone can give me some useful info?

That is a very good link regarding frequency and timing posted by Sniper69 ..Take a look at it and you will understand more.I learn mine from there as well..About OCing, i have no idea at all as i am still noob in learning about OCing ram.

Good link.
Definitely, higher frequency and tight timing is good. But low frequency and tight timings not all time better than higher frequency with little loose timing then the lower frequency.

Hi,
currently I'm using 2x512 Kingston 667 ram.
I plan to upgrade it. I'm not sure whether to get 1Gb or 2x512Mb.

Also about the dual channel, it only works when there is two ram of the same specs?

better get 2 x 1G or 2 x 2G(if your pocket fat enough)....

anyway... C-zone now offering RM195 for 1G 667... dunno if the price will drop again... anyone can advise or I should grab now as well......

hi, newbie here, can i use 2 pcs of different ram together?
1) 256mb PC2-3200-333
2) 256mb PC2-4300-533

it comes like that when i bought the damn acer aspire pc
sometimes can boot sometimes cannot.. dunno whether its because of this..

My advise try to go for 2GB pack. But it is ur choice whether VS ram or performance ram.

i got 2 sticks Kingston 512MB DDR667 in dual mode....
If i upgrade with additional sticks of different brand (total 4 sticks)..i would lost all dual channel capability?

That really depends.Some can, some cannot..Currently, i am using 4piece of Corsair ram (different model for each pair) and still be able to run dual channel.Tested the same pair of corsair with other brand as well such as GEIL, OCZ and Kingston before and still be able to run dual channel.

Note: The ram that i had tested are able to run Dual Channel as a pair which means all of the ram i test are able to run dual channel by themselves(a pair).Not sure whether they will work for you or not cause there are plenty of problems that are related to match and mixing different ram which might have different chipset, revision, timing etc...

It is depends on the RAM module you had been used. but one thing for sure is that for 4 module running all at once, you cant get the max frequency of the ram slot. By default the frequency will get lower one step.

Based on my reading sometime ago, there is not necessarily bad thing to run at lower frequency as well as it it not necessarily good as well.

I hope you can Google a little bit to find your best solution. Good luck.

Agree with you here.But this is caused by having rams with different chipset, timing, brand, revision, etc.I guess if we are having the same pairs of ram should be fine.Last time when i tested the GEIL and OCZ, my frequency was pushed all the way down to 100Mhz but with a very good timing of 2.5-2-2-5 (originally at 3-3-3-8).But, a slight tweaking in the bios can easily help me get back up to the original frequency of 200Mhz (of course with a looser timing)..Therefore, my best guess is that the problem in frequency might be caused by mixing rams..

Hi,

I'm using 4 X 512MB DDR2 667 rams, should I try with 2 X 512MB to OC it or just stick with all 4 pcs. ? I've been getting 800MHz with stock voltage @ 4-4-4-12, when I hit 1000MHz, I can get a stable performance from 5-5-5-15 @ 1.9V, but can't seem to get stable performance for 4-4-4-12 eventhough I'm using 2.1V, any way to improve it ? should i try 2.2V ? Coz i'm not sure if its safe or not.

thanks in advance for all the advices.

Let the timing more loose at the 1000Mhz unless you are using very good performance ram which can get the stable at the particular timing when OC-ed.

Maybe you can try pushing the voltage more than stock V, but i would suggest you check with vendor/manufacturer technical spec if anything happen.

Hi all experience master outside, just wanna ask, i had a 512MB Apacer PC3200 CL3 ram in my Abit nf7-sl board, can i upgrade it with another Kingston 512MB ram? cause some of my fren claimed that Apacer only compatible with Apacer, mean both slot of ram also need to be Apacher, cannot mix with Kingston or other brand. is it true?

You can upgrade the ram and use them for casual but there is no certainty that the setup will be in stable mode.

The best is, try to look for identical model ir order to get stable dual channel setup.

Hello "" I'm using 1gb pc4200.. The shop near my place only have pc5300 and above for 1gb.. Should I just get that ? It will run at the lower pc4200 speed right?
