Ok everyone, bare with me here.. I have a
HP Pavillion a6009n with 1024 MB of PC2-4200 DDR2 RAM, It's two of the
512MB
GE Force 6150 and all that good stuff

My question for the forum is I want to add more RAM. I'm not sure how
it all works.. on Circuitcity.com you can enter ur exact comp model
number and it finds what ur computer needs.. so I've done that and have
decided to get Kingston or the ACP-EP,
both are 1GB DDR2, but both are PC2-5300 (667MHz)..
Thats what it said to get online.. so my question is:
1. is it ok to mix different brands of RAM,
2. I'm Running Dual Channel, with two 512 Cards is it bad to mix a
different kind, size, and speed in the 3rd slot... will it change how
the Dual Channel works... I'm not sure how all the RAM stuff works.. if
anyone can please please help me I'd really appreciate it. please
message me back here, or at

Thanks again..!

1. Generally yes, though it may disable dual channel support.

2. Will definitely disable dual channel. For proper use, dual channel
requires that each pair of memory slots have the same size, speed, etc,
preferably in "matched pairs" that have been tested to ensure they will work
the same. Sometimes mix and match works sometimes not. The memory will
work but dual channel mode will be disabled and you'll take a performance
hit if you install memory that won't work in dual channel.

Sometimes Dell ships machines with ECC ram. If you have ECC ram, you
can't mix it with non-ECC ram. Don't make that mistake, but if your
board is running ECC ram already, you'd be better off to just disregard
it and buy all non-ECC because buying ECC to match is more expensive
than buying all new RAM. I think CPU-Z will tell you if you have ECC
RAM.

Also, you can buy any DDR2 ram that is PC2-4200 or higher.

DDR2 RAM is so cheap these days, it's a shame to have too little.

Although you can sometimes get away with it, the safer thing to do is
to have everything the same, including the brand.

Same thing. You should get everything as close to identical as
possible. Besides your running the risk of incompatibility if you
don't, you'll lose performance if you disable dual channel by not
having these the same.

get instead of 1 GB.. i could get another two of the 512MB ones and put

ran CPU-Z and it says the RAM is from like hyundia electronics.. thats
what was stock in my HP.. lol.. what shouild I do.. I just wanna add
more and have it work better.. let me kno.

To make it simple, buy this...

'Newegg.com - G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2
6400) Dual Channel Kit Desktop Memory - Retail'
(http://www.newegg.com/Product/Produc...82E16820231098)

remove the stock memory a discard it. Install in the same locations as
the old ram. Better yet, buy two kits and install one in each of the
four available slots.

Dual channel will still work, and you'll have 4Gb RAM for about $100.
Windows 32 bit systems will only see about 3.25Gb of that, but that's
ok. G-skill memory has a good rating overall too. If you're not
farmilliar with NewEgg, they are a reputable store...very reputable.

I am quite sure of this. Somebody back me up so he can feel confident
he is buying the right stuff.

oh ok.. thanks.. ya I've heard of newegg before.. no worries.. that ram
will fit right.. ya I think I will just get a set of two 1GB cards from
newwegg or from curcuit city or something and just do that.. thats
double what I have now and I'm sure i will notice a difference.. would 4
GB make it that much more noticeable??? I'm not to familiar with how
much RAM helps comps (I kno what it does) but is 4 that much more
amazing than what 2 would do?.. anyways thanks for ur help. let me kno
what you think of that idea I just posted.. thx again!

Going from 1gb to 2 will be a very noticable increase. After that, it
really depends on what you do. You probably won't see too much
difference with additional RAM after that unless you are using programs
that consume large amounts of RAM. Personally, I would put in 4gb, but
if you put in two with the solution I mentioned above, you can buy
another kit if you're not happy. My main point is don't bother trying
to match your existing RAM, Just remove it. You'll spend more trying to
match it, and you'll end up filling all your slots to acheive just 2gb
leaving you no alternative when you decide you want more, but to toss 4
sticks of ram.

My opinon...dump in two 1gb sticks. If you feel you need more, get
another kit. I put in 8gb on my system, and I'll admit that it was
overkill. The good thing is that I won't be needing ram for a loooong
time.

I don't know what you'll get at Circuit City, but I do know that 2Gb
G-skill DDR2 @ $45 and free shipping is a great deal.

Also, if you try and match the old RAM, "identical" ones you might find are
bound to have different modules in them!

ok so tell me this.. I am going to get RAM right now. I have a freind
that works at COMP USA so I'm getting 25 percent off. can't say no to
that.. I'm gettin two 1GB Corsair XMS2 DHX chips, ddr2 pc-6400 at
800MHz.. I think that 2 GB will be enough.. plus i read up and corsair
is a highly recommended brand... so here is ONE more question. I was
told to pull out old ram instead of trying to match with my old stuff..
so my plan is to pull the two 512 cards out and put in these new ones..
but now I think about it can I pull them out and then put them in slot 3
and 4.. so I will have matching 1gb chips.. and the other dual channel
will be the stock matching 512's for a total of a lil over 3GB.. can i
do that, Will that work? or is it not good to mix sizes with the 2
channels. if anyone knows what I should do please let me kno. otherwise
I'm just using the two 1GB til i hear what to do with my old ones..
please get back to me ASAP.. thanks again everyone for ur input!

/Cory
