What is best in performance?

[Guest]

I have the opportunity to upgrade my RAM memory to 256 RAM cheaply, but now i have the question : what is best : 2 x 128 MB or 1 x 256 MB or doesn't it matter at all???

Usually two sticks of 128MB are a little faster, but a more important consideration is the brand of the RAM. Mushkin is about the fastest RAM you can get. One 256MB stick of Mushkin Rev.3 is faster than two 128MB sticks of just about any other brand. If you want speed get Mushkin.

Thanks

If you're looking towards more of a price/performance balance, get Crucial.

I also like Crucial

Why would two 128 mb ram modules be faster then one 256 mb ram module ?
Could ayone please explain this to me ?

thanks



Hey man i dont know .. i just think i do !!

The less memory addressing the CPU has to do, the faster. With large quatities of RAM, esp. in one stick- the CPU has the daunting task of having to address it all and put crap in it. 2 sticks requires less addressing. =)

There's a short but neat article on this at <A HREF="http://www.lostcircuits.com/memory/rev3/" target="_new">http://www.lostcircuits.com/memory/rev3/</A>. This guy took a Mushkin 256 mb rev. 2 DIMM and unsoldered the RAM chips on one side of the pcb...and apparently invented a 128 mb stick of Mushkin rev. 3! The result was that the 128 mb stick could reach a higher FSB.

I've done my fair share of soldering in the past, but I'm quite sure I wouln't want to tackle that...if I paid for the DIMM.

Very interesting. I didn't know that.
Thanks for the information.

a single 256 MB DIMM will run at higher frequency and lower latency settings than two 128 MB DIMMs made of the same chips and using the same PCB. However, the other side of the coin is that even in a single DIMM configuration, the added load, caused by doubling the DIMM's density will have a negative impact on the top frequency and, in particular, the CAS latency.

Sorry to be a bit simple, but what is this actually saying? Are they exactly the same or does the former outweigh the latter?
