Hardware :: DDR2 800/667 RAM On A 667 FSB - Comparison
Feb 9, 2010
I'm looking at a new board that supports both DDR2 800 and DDR2 667. But, the FSB is only 667MHz. My question is: is there a benefit of using the DDR2 800 on the 667 FSB? That is, can the DDR2 800 be fully utilized on this system? What are pros and cons of such? Does the added benefit outweigh the additional cost of the RAM?
Note: I'm not looking to overclock at all, and this is not going to be used for 3D apps (games or video editing).

I just purchased this laptop a few days ago and already I am wanting to upgrade the RAM and such. In the terminal when I typed 'sudo lshw' it gave me all of my system information and I have two RAM slots, one is 1GB and the other is 2GB. This laptop can be maxed out at 8GB which is my plan but the RAM in here is 800MHz DDR2. What exactly does the 800MHz mean and what happens if I buy RAM that's DDR3? Do I have to get exactly 800MHz DDR2 RAM when I upgrade or can I order better? The ram I was looking at is two sticks of 4GB(4096MB) DDR3 1333MHz but will this even work in my laptop or blow it up?

I'm wanting to update my existing 1GB Kinsgston 240 pin DIMM memory to 2GB or more. Can I keep my existing IGB and add another from a different manufacture? Will they match or should I just get new memory? What is available is DDR3 and DDR2. Guess what I'm asking is I have two memory slots total one will have the existing 1GB and I want to add at least 1GB more, does the DDR3 or DDR2 matter? Or is it all about the 240 pin config?

Just installed 2 pcs of 2GB DDR2 RAM specifically KVR80032N6/2G-SP from kingston. For dual channel as my board supports it plus the memory I could afford to buy now. Though I am using the RAM for shared memory -- I don't think it's using a lot. If I understand it right 2GB is roughly equivalent to 2048MB. So two of these becomes 4096MB -- less 256MB for the shared video ram -- that would be around 3840MB. Unless my board is using 512MB of shared video ram and that would be 3584MB w/c is closer to 3.6GB. Never mind I'll just check my shared Video RAM.

I'm very new at Bash scripting and have a bone head issue that I'm trying (and failing) to resolve. I cannot get this one IF statement to work, it seems the comparison operator does not think the resulting number from the $b*$c+$b operation is an integer even though it is a number. Below is a small proof of concept script with the bit I'm having trouble with.
Code:
#! /bin/bash
a=800
b=700
c=.15
if [ "$a" -le "$(echo "($b*$c+$b)"|bc)" ]

I know it is wrong to use the "==" operator to compare the equality of two floating point numbers. Logically it would seem that if the "==" operator is not usable for floating point comparison, then the "<=" operator would also not be usable. Is this true? The lack of google search results on this topic made me think that it must be true. If that is true, then is it true that the only way to compare floats with <= or >= is with something like the code below? Code: bool smaller_than_or_equal(float a, float b) {
if ( fabs(a-b) < EPSILON){return true;}
else if (a < b) {return true;}
else {return false;}
} I think this is a general question, but if specifics are necessary, I am using the C++ language to code at the moment.

I don't really understand the CPU technology where there are different CPU speeds. I feel it is hard to compare them nowadays. For example, I have been using my laptop with Pentium (R) 2Ghz. Now, I am thinking about buying a new laptop with Intel I5 1.33GHz (Tablet/laptop). Is my new laptop going to be slower than my current one?

I am just looking for an application that given two directories, for example /home and an USB disk of 500 GB, can comparate the files and subdirectories present in each directory, so I can know the files that are present in one directory but aren�t in the other.I do not know if the explanation is clear. but I just need some tool that can indicate me what files to copy from one place to another when periodically I do backups of my data...

i have used many Hex Editors in windows, almost all had comparison features, even notepad++ to an extent could do this. I have 2 binary files, i just want to compare the differences easily and graphically, in windows HexWorkshop did this with the click of a button. I have tried 5-6 editors from the ubuntu repos but none have this option
2) Is there any desktop video capturing software that are more catered for tutorials etc where the whole desktop is captured. (Camtasia for windows i know it a massive bit of kit, but thats the sort of software im on about)
I have tried recordMyDesktop, XVidCap and a few others. However, they capture XServer and therefore things like desktop effects arent recorded. I have used VLCs screen capture which to be honest is better than the other 2 software i mentioned for recording the whole screen, but options are very limited.

I had a hack on my oscommerce website recently. I have put in the relevant security patches but I need to check whether the hacker left any code changes in my files. What is a good file comparison software for linux? I need it to scan though the current files and folders and compare it the original default oscommerce installation so I can check the code.

I need to be able to compare a file date with system date and delete files older than 30 days.
the file name is basically
error_log.03222011
of course the extension is the date the file was created.
Oh and before i get hammered I looked everywhere but am unable to make sense of what I found.

I have a bash script that is tracking ERROR connections (running in a cron every 15 minutes), sometimes the errors are true and are not connecting. But most of the time, the disconnects/reconnects are between 30 seconds are sending out false positives. I am looking for a time comparison code to pick out the 30 second disconnects and know that this is and "ok" error. Here is a section of the log with timestamps, errors, etc.

I am fairly new to linux still and I'm currently trying to write a shell script (which I have never done) that is supposed to run the xrestop(like top) program. What I want to do is execute the program and check the identifier column to see if a certain program is running. If it is running I want to strip the data from that row of the terminal say every 5 seconds or so and put it in a text file. Is this going to be a complicated thing?
Heres a list of the columns when you run xrestop program res-base Wins GCs Fnts Pxms Misc PxmMem Other Total PID Identifier.

how do I get this regular expression to work in an if/else statement? This is just a little script for learning BASH. don't be too harsh.
This script will test if a certain number of files with 1-4 in their filename exist and print their filename. An error message will be printed if not.
#
for i in `ls file[1-9]`
do
if [[ "$i" == *1-4 ]] ; then
echo "This file, $i, ends in a number between 1-4"
else
echo "Error, this file, $i, does not end with a number between 1-4"
fi
done
I get this error. ./file_test.sh: 13: [[: not found
