<div dir="ltr">I emailed the company I bought the ram from and they said they would send the 800 Mhz instead of the chips advertised. If that happens I don't know.

I would say at least in part the cause of your computer being slow is the CPU.<br>
<br>
I'd be interested to hear if more RAM makes a difference. Of course RAM might effect performance if you are doing something that requires a lot of RAM. I assume more RAM will effect compile speed.<br>
<br>
This is a testament to Linux breathing life into old iron.<div><div class="h5"><br>

It seems the max memory is 4GB for that system - 4 banks of 1 GB<br>
sticks.<br>
RAM memory Capacity - 4 GB<br>
Memory Type - DDR2 SDRAM - DIMM 240-pin<br>
Data Integrity Check - Non-ECC<br>
Speed - 667 MHz ( PC2-5300 )<br>
Features - Dual rank , unbuffered<br>
<br>
You already have 2 1GB sticks in the machines - what speed are<br>
they?<br>
You should match the speed for all four sticks.<br>
<br>
The second set you mentioned are only 533 MHz, whereas your bus is<br>
667<br>
MHz. If your system is slow, get the fastest memory you can afford.<br>

Yes, 1024 is one gig, but often some memory is stolen by the<br>
motherboard – for example if you have an on-board graphics card<br>
that uses main memory for its RAM.<br>
<br>
<br>
<br>
Personally, if you can afford it and the 4G is less than 2x the 2G<br>
I’d get 4G – but if you could find 2x2G sticks then you could<br>
have 6G total – not bad IMHO.<br>

I know this is a stupid question but...<br>
<br>
<br>
<br>
I got a Dell dimension c521. It is slow so I figure I should add<br>
memory. There are 4 memory slots with 2 being used. How much memory<br>
is that? Well, the cards that are in there say it they are two<br>
cards with 1024 mb apiece. 'free -h' reports<br>
<br>
<br>
<br>
free -h<br>
<br>
total used free <br>
<br>
shared buffers cached<br>
<br>
Mem: 1.9G 1.4G 489M 18M<br>
59M 535M<br>
<br>
<br>
<br>
isn't 1024 one gig? Where is the rest?<br>
<br>
<br>
<br>
SHould I buy this?<br>
<br>
<br>
<br>
NEW 4GB 4X1GB DDR2 PC2-5300 667MHZ RAM MEMORY FOR DELL DIMENSION<br>
C521 [1]<br>
<br>
<br>
<br>
or should I get this?<br>
