Hi, I had also 8Gb memory installed, but windows 7 32bits can only address 3Gb. If you want to use all memory you'll have to upgrade to 64bits.

I bought myself two new machines at the time, a desktop with a 3.3 Ghz i5, and a laptop with a 2.2 GHz i7. Naturally I installed GNS3 on both, but only really tried it in earnest on the laptop last week when I had some spare time while on a contract, eg they ran out of work for me for a few hours. So I started building the configuration used in the Cisco CCIE book for an MPLS example. This finished up with 12 routers, ten 3745 and two 7200 where I needed more interfaces than the smaller routers could do. Once I had it configured up I found that I was getting some odd errors like non matching duplex on fast ethernet interfaces that are actually configured to match, and knew from previous experience that this probably means the machine is struggling a bit...sure enough, task manager showed that it was running all processors at 100%. It didn't seem to be an idlepc issue. I tried a few different values for each of the routers but no improvement. So then I shifted the whole configuration over to the desktop, where it runs fine, the processor load sits down low with only the odd peaks reaching 25% utilisation. Ok, so the machine that was struggling has a slower clock speed, but only 2/3 slower, surely not enough to make that much difference, and it is an 8 core machine rather than 4, which should help. But the other main difference is that the desktop is running a 64 bit version of windows(home premium) while the laptop is running a 32 bit version, Professional. So do you guys think that this could be the difference? If so I may as well look at getting an upgrade for the laptop. Both machines have 8 GB of ram installed, but I wonder if the laptop gets the full benefit of this with the 32 bit OS on it? regards John _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com<http://www.ipexpert.com> Are you a CCNP or CCIE and looking for a job?
