View Full Version : What's better?: 512MB PC2700 or 1GB of PC2100?

My bro just got himself an Acer Ferrari laptop w/ 512MB (2 sticks of 256MB) PC2700. He wants to take the RAM from his old laptop, 2 sticks of 512MB of PC2100 so he can get 1GB on his new machine....

I personally would take speed over the quantity, but really, for 3D and CAD, what would be better, lots of slow RAM or half the amount in fast RAM?

Personally, I'd say the faster RAM would be the better choice. It takes a lot to use up the 512mb I have (unless I'm running a lot of apps at once). But more importantly, if either way proves insufficient, it's cheaper to upgrade to 1gb by just having to buy another 512mb of fast ram than to have to replace all of your ram...if you get what I'm saying. :)

I would take the 1 gig of slower memory myself. The extra headroom it offers will greatly reduce the chace of hitting virtual memory.

Just remember that 25% slower memory will not give a 25% slower machine, the memory speed is a much smaller part of the equasion. Plus it is possible the memory can be overclocked back up to 333mhz

I would go for the 1GB, espeically if you use a lot of apps or big apps.

The answer to this question is clear:

1. If the computer requires PC2700 ram modules, then PC2100 simply won't work.
2. If the computer requires PC2100 ram modules, then PC2700 modules will work but they won't bring any speed gain, since they are going to work at PC2100 speed.

So if your brother's laptop supports PC2100 ram (which I doubt since it came with PC2700 modules), definitely go for the 1 Gb option. If not, then you have no choice but to stay with the PC2700 modules.

If a computer wants 333mhz pc2700 memory then slower 200mhz pc2100 memory WILL work.

Just FYI, PC2100 memory runs at 266 MHz, not 200... And I never managed to make a PC work with ram that is slower than its memory bus.

That's odd, I was able to use PC100 RAM in a system meant for PC133, DDR shouldn't be any different.

One thing to keep in mind - if it is a new laptop, will changing over the RAM void the warranty?

More (but slower) RAM.

Just remember that 25% slower memory is a LOT faster than 600% slower disk drives.

I'd take the RAM any day of the week.

Nah, most notebook manufacturers make RAM more accesible to users.

More ram. The virtual pagefile will make up for the speed difference.

Sieb is right. More ram, the fractional speed increase of the smaller memory option will be completely lost if you spend all your time paging from disk (which is hundreds of thousands of times slower than accessing data from memory).
