More RAM . . .
Well, another day of setting up my new computer, loading software and optimizing the machine.
The new one has 12 GB of DDR3 RAM, but has room for 16 GB, so I took a 4 GB stick from the old machine and maxed out the new one. Within limits, the more RAM, the faster your computer will run. In fact, it can be one of the cheapest ways to speed a computer up if it only has 4 or 8 GB to start with.
The reason for this is that as the computer computes, it uses up memory (RAM) as it runs programs. And if you’re running a lot of different programs at one time, or have a lot of tabs open on your browser, you can reach a point where you essentially run out of memory.
And when this happens, things really slow down. So to keep running, the computer starts paging data out to the hard drive. Now hard drives are fast, but compared to RAM, they’re snail slow. So everything slows to a crawl.
And, even worse, you don’t have to have a lot of programs running at one time to have this problem. You can also run into this by running a lot of different programs one at a time.
A lot of software is not very well written , and has ‘memory leaks’. When a program runs it is allocated a certain amount of memory in a specific area of RAM. And when you quit the program, that memory is supposed to be released and available for other programs. But many times this doesn’t happen correctly and all of the memory area is not released. So over a period of time, the system has less and less memory available for use. One quick fix for this is to just reboot your computer once a day, and get a fresh start on memory usage.
So the more RAM you have, the longer this slowdown is delayed.
One of the problems I’ve run into setting up the new computer is that I can’t get the HDMI port to work. The computer monitor hooks up using a DVI cable, but I use the HDMI interface to connect up our 32” LCD TV at the front of the rig.

My old computer output video on the VGA port and HDMI simultaneously, with no switching necessary. So we just use the TV remote to change the input from HDMI-1 to HDMI-2. But it doesn’t work on this new machine.
When I plugged the HDMI cable from the TV into the computer, it kills the DVI output to the monitor. And nothing shows up on the TV either. I tried a bunch of different things with no luck.
The computer does have a way to switch back and forth between outputs, like you can do on a laptop to output to a video projector. But this doesn’t work either.
So I’ve got some more research to do on this problem.
A little before 5, Jan and I headed out for dinner and Wal-Marting. Our dinner stop was a return to the Asian BBQ & Grill, a place we were first introduced to by Sherry and Clark Bennett back in February, and a return match with Brett and Frankie O’Neal a week later. And it was just as good this time.
We started out with our usual Shrimp and Pork Spring Rolls.
Then we moved on to Jan’s Lemon Grass Chicken
and my Beef Phở, which were both delicious.
Wish now we hadn’t waited so long to return, and we’ll definitely go back in a couple of weeks when we’re back in the area.
Then it was on to Target for a few things before finishing up at Wal-Mart. It was really noticeable how much busier Wal-Mart was compared to Target.
Tomorrow I’ll start prepping to get ready to travel on Sunday, checking tire pressures, putting away stuff, and running through my Checklist.
