Need Memory for my e1505 ?

I want to upgrade my e1505's memory, so I've come to ask advice...

I currently have:
e1505 - T2500 & 2x512mb PC2-4300

I would like to have 4gigs, but if the latency will be much more noticeable then 2gb then I'll go with 2 gigs.
Would it be better to buy 1x2gb stick or 2x1gb sticks ?

Also what is the fastest ram I can get for t he e1505? I remember hearing a rumor that the e1505 doesn't play nice with anything over DDR2-667 / pc2-5300 (i.e. PC2-5400 & PC2-6400), is this true?

Thanks for the help,

Crucial says the maximum memory for the E1505 is 2GB (2x1GB modules). Are you sure the E1505 can handle 4GB (2x2GB modules)?

 

2GB is more than enough--I don't think 32 bit Windows can address more than 3.25 GB anyway (plus I believe that the MOBO of the e1505 is only rated for 2GB. 2GB modules are terribly expensive, and you will not notice a difference. You will need 200 pin SODIMMs and either PC53/5400 (667 MHz) or PC 43/4200 (533MHz) The difference is negligable because while the PC5400 is faster, it has a higher latency, usually CAS of 5(time to recharge between cycles). PC4300 is slower, but has a lower latency, CAS of 4. Get whichever is cheaper (some like to match their RAM's clockspeed to the FSB speed, if you are one of them you'll want 667MHz RAM) Remember, the e1505 only has 2 RAM slots.

I don't believe that there is any faster notebook memory than 667 MHz, but I could be wrong.

 

I don't get it - the e1505 has the same chipset as all the other Core laptops that can handle 4Gb. Maybe it's a heat issue?

In any case, 667Mhz or 553 Mhz is no big deal.

You want two identical modules to get Dual channel.

2Gb modules are still insanely expensive.

Soooooo, 2x1Gb is my best bet for you.

 

Don't know... that's why I am asking the experts

 

Experts?
Looks around

Where?

 

2 gb sticks are a waste of money right now, when 64bit programs become mainstream it will become useful, but for now its just really expensive and will not give you any tangible benefit, by the time 64 bit operating systems are the norm the prices should come down to a reasonable level, and while the chipsets are the same, the 4gb boards have been tested and approved to run that capacity, the ones that are listed as 2gb max, might run 4gb, then again it might not, with the prices how they are, and most online retailers not taking returns on memory these days, thats a pretty stiff gamble, 2 gig is all you will ever need for a 32 bit OS

 

Is there a difference between pc2-5300 & pc2-5400 ?
If so how noticeable?

p.s. Does the e1505 support; PC2-6400 ?

 

PC2-6400 comes with 800Mhz clock... the e1505 chipset has FSB 667MHz, so you might be able to use that RAM but it would not be performing up to it's intended clock speeds.

 

Stranger is right, pc 6400 will work, but you will only get 667mhz out of it so you wont gain anything, you could get it thinking you'll just put it in a new laptop down the line that fully supports it, but by that time it will most likely be obsolete, the difference from 533 to 667 is negligible, I would go for either one of those,2x1gb, whichever is more cost effective

 

Thanks guys... can someone help me with this one:

 

No, there's not much gain from 5300 to 5400. 5300 ram will bring you up to your chipset's supported clock of 667, so anything higher is pure waste. But I have seen 5400 ram selling cheaper than 5300, so buy the ram that's more price worthy.

 

Thanks to everyone for the help...
Now time to scour fatwallet.com and slickdeals.net for some SODIMM's

 

Wait... one more question ;-)

Whats faster/better 1x2gb or 2x1gb ?

 

I have a question. If my laptop has a T7200 with 667MHZ FSB, will 533MHZ ram bring down the speed of the overall system?

 

2*1gb due to dual channel

 

Your asking if the 533 ram will slow your cpu from 667 down to 533? It shouldnt, I had an el1505 with a core duoT2300 667FSB, with 533 ram and it ran just fine, if the bus was lowered, it would be reflected in the clockspeed of the chip. Multiplier X FSB. As far as I'm aware all you really get out of 667 ram at the moment is slightly faster benchmarks, no real world gains to speak of. I wouldnt worry about it, either or should suit you just fine when its all said and done.

 

2x1Gb *will* be faster than 1x2Gb, by 10% at least.

However, as others have said, it's unlikely you'll see any difference between 553 and 667 MHz, due to the lower latencies (i.e. quicker operation) of the 553 memory.

 

Dont forget that with the intel 945 chipset, you Can run mismatched pairs in dual channel, if you are upgrading from 2x512, you can run run 1x512 and 1x1gb without problems, and with dual channel support.
