Always, always there is the quest for more speed from my computer.  I admit it ... I'm impatient and I like to have a fast computer.  What geek doesn't? 

So ... with that in mind, I went down the path of my yearly system upgrade.  It's not as radical as last years (when I got a new processor, motherboard and memory), but the performance improvements are still dramatic. 

You see, I've always wanted to have a dual processor system.  More processor ... more power ... more speed.  And, while many average computer users really wouldn't be able to take advantage of a dual proc system, I always knew that I'd find a way.  Actually, there have been many times that I've wanted dual proc ... like when I'm doing something that's CPU-intensive (like compressing or decompressing large VPC's) and it ate all the processor cycles.  When that happens, you can't do much until the operation finishes.  Not a lot of fun. 

So ... when I bought my motherboard last year, I did so quite deliberately ... and I chose a Socket939 board so that I could upgrade to the promised AMD Athlon 64 Dual Core processors when they released ... with only a BIOS update.  And that's exactly what I did.  I hooked myself up with an AMD Athlon64 X2 Dual Core Processor ... the Athlon64 X2 4400+ with 2 2.2 GHz cores.  If you remember, last year I got an Athlon64 3500+, which as 1 core running at 2.2 Ghz.  The new one also has 2 1 MB L2 Caches, compared to 1 512 KB L2 cache on the 3500+. 

So what's the result?  I've been running the new processor for about 2 weeks now and I have to say that I'm just tickled by it.  Not only is it just plain fast ... I can more effectively multi-task when doing CPU intensive operations (yes, I specifically tried that!)  The only thing that has been an issue has been Virtual PC ... and this caused me quite a bit of consternation as I run a LOT of VPC's and this was certainly a big reason to get the dual core (not that the VPC could use them, but so I can do other things at the same time).  Certain VPC's would BSOD with an issue in Processr.sys ... DRIVER_UNLOADED_WITHOUT_CANCELING_PENDING_OPERATIONS.  Now, I agree, this doesn't seem like a very nice thing for a driver to do, to unload wihtout taking care of it's pending operations, but I was somewhat disappointed.  I did, howver, find a solution.  There are 2 things that you can do:

1.  Boot in safe mode and let the processor driver update.  This worked ... but I didn't try re-running the VPC on my laptop, where I fear I'd have to do the same thing. 

2.  Disable the driver.  This is described at ... this works as well and is now the solution that I use on all of my VPC's.
