Ram combinations???

kusty · 01-23-2006, 08:38 PM

I just replaced a 128 ram card for a 256. I have 3 slots
(XP) and a possible 1.5gig memory. Would it hurt to throw the 128 back in, and if not, does it matter if it is in the first? or 2nd slot? Not to sure. I imagine I can but just need a second opinion.

Thanks, looks like a great forum. First time here. Thanks guys!

first off sometimes different ram sticks don't like each other so you can just try and see what happens, but yes it is possible.
second if the ram have different timming they will operate at the lower timming hence slowing the faster ram down
third it is always better to put the largest ram size into slot 1

hope this helps

Will give it a shot in the morning...will post results.

Thanks again

Kind of a similar question, I was looking to buy a new memory module for my PC. The Mobo uses PC2100, but I was reading around, and basically it seems to me that I can put in faster memory, and even though it will only run as fast as the PC2100 I have installed, it will still work perfectly. The only catch I have read about is that I have to make sure to get low-density memory (64x8) and make sure the error correction/parity matches. And if I ever want to plug it into a faster mobo, the memory will only be limited by the mobo's FSB speed. Do I have all this info right?

Are there any downsides to using fast memory in a slower system? Would it draw more power or generate more heat than my PC2100 memory?

all sounds good

On the power / heat thing I think you should be OK but just check the voltages of the one you are going to buy to make sure they don't require different voltages as you can under power your ram or maybe fry it if you put too much into it
With heat, 2 sticks of ram will generate more heat than one but i don't think it really a problem as it is only minimal in the scheme of things.

P.S it is not a good thing to Hijack a thread so just start a new one in the future

Sorry, I thought somebody might get mad if I started another thread that was so similar to this one. Thanks for your input!

Was no significant change. Did however decide to just leave it out.
