SSD upgrade

A couple of months ago, I gave my computer its first significant upgrade since I buffed the RAM to 24 GB.

I’d been wanting to add a SSD drive to the system for a while now, and finally bought a 250 GB Samsung EVO 850 to function as the boot drive.

Installation was pretty easy. The hard part was fishing out a spare power cable and finding a spot to secure the drive. The case is technically out of free drive bays, but SSDs are pretty thin, and I was able to find enough space between the CD drives and one of the hard drives to secure the SSD to.

Once the drive was installed, the computer got a fresh Fedora 25 install with the SSD as the boot drive. As expected, once all the packages were downloaded, installation went quickly. Really quickly. For a fresh install I’m used to leaving my computer alone for an hour or so while it’s installing packages. With the SSD, everything was installed and I was rebooting in under 30 minutes.

Boot times for my computer are around 1/3 or so (haven’t really timed it) of what it used to be booting off the spinning disk. A couple months in, I haven’t noticed any significant change in performance and there’s still plenty of room left on the SSD.

The original boot partition has been changed to a /var mount point and now the computer is on Fedora 26 Alpha.

Now I want to get SSDs to put into my laptops.

Going wireless on the desktop

Broadband Internet service at the new house comes from Home Telecom in the form of their Velocity Fiber service. They offer up to 1Gbps service, but we opted for the more modest 50 Mbps plan which is more than sufficient for our needs.

Installation at the house went pretty smoothly, but could only be installed at one point in the house in the form of a CAT5e cable. I was expecting something similar to Comcast where the broadband would come in via coax and cable modem. In retrospect, I probably should have asked.

I chose to have the installer put the drop in the structured wiring box, figuring I could route it through the rest of the house pretty easily from there using the CAT5e wiring that was run through the house for phone (there turned out to be some kinks in that plan, but that’s a story for another post).

The room that’s become my office and where my desktop is, unfortunately, doesn’t have a CAT5e drop in it (oversight on my part during the planning process). That meant to get online, my computer would have to go wireless for the first time.

Since I couldn’t find where an older USB WiFi adapter got packed away, I did some shopping around and picked up a TP-Link Archer T8E PCIe card from Newegg. Looked like it would be a decent performer and the reviews mentioning Linux said the card worked fine under Fedora and Ubuntu.

Installation of the card was quick and painless, but I couldn’t get Fedora to bring up the card, even after a fresh install of Fedora 24. The kernel detected the card, but the drivers wouldn’t work with it.

A bit of digging showed the adapter uses a Broadcom BCM4360 chipset, which wasn’t supported by the b43 drivers.

A little more searching brought me to this gist containing a script for installing Broadcom’s wl driver. Downloaded the driver source, compiled and installed, and the WiFi interface popped up. Didn’t even have to reboot the computer. The computer was back online.

The Broadcom wl driver and associated kmod/akmod files are also in the RPMFusion non-free repo, which seems to be catching up with the Fedora 24 release now.

With the proper drivers installed the T8E card is performing pretty well, even with the computer chassis almost directly between the card’s antennas and my wireless router. I’m able to get pretty much the full 50 Mbps from the Internet and can see about 7 other WiFi access points in the neighbourhood. Not sure about what kind of signal strength the card is seeing from my WiFi router, but it’s at least enough for a solid connection. Haven’t tested transfer speeds on the internal network yet but that should still be pretty speedy.

Despite the minor driver snafu, I’m pretty happy with the way the card is performing in the computer and under Fedora. Not quite the “works out of the box” experience I was expecting but still pretty painless.

Time for some computer hardware changes

This computer of mine has passed the 6 year mark and it’s time for another round of upgrades and replacements.

When I put in the new power supply, I didn’t exactly do a great job of routing cables. I want to get in there and try to tidy some of that cable mess up.

I noticed a few days ago that CPU temperatures were running a good bit higher than usual, around 50°C at idle and as high as 90°C under load (according to gkrellm). It’s got one of those closed loop liquid CPU coolers which as far as I can see hasn’t leaked. The fans and radiator get a good cleaning out at least a couple times a year, and the air being exhausted is definitely warm. I’ll start with taking the cooler off, cleaning it and the CPU off and applying some new thermal paste. Hopefully that will help things. If that doesn’t work, it might be time to replace the cooler.

The MX1100 mouse that came with my old Logitech Wave keyboard finally seems to have bit the dust now. Fortunately I was able to scrounge up a spare mouse from the junk box to use while I search for a replacement. The MX1100 will be tough to replace though. I  really liked the feel and weight of it.

I’ve been seriously considering replacing (or maybe adding…I think I might have a free SATA port or two left) an SSD drive. It would be a good opportunity to re-do the disk layout on the computer and rearrange things. I’ve been wanting to start off with a fresh new home directory to get rid of some of the dead weight that’s accumulated in there over the past dozen or so Fedora releases.

The computer maintenance work will have to wait until we move into the new house. Everything will be disconnected anyway, and it will be a good time to give the computer a thorough cleaning before getting it all set up again.

New power supply

Ordered a new computer power supply after we got back from Rome to replace the old one that flaked out. Went with a 750W EVGA SuperNOVA G2 supply from Newegg based on favourable comments at The Tech Report and jonnyGURU.

The power supply came in a nice sturdy box, and was securely packed inside.

All the cables that can plug into the power supply along with some cable ties, screws and a testing plug that lets you test the power supply without having to plug it into a computer.

It’s a pretty slick looking power supply that comes in a nice black finish.

The modular connectors are all labeled so it’s easy to figure out what cables go where.

Plenty of ventilation holes out the back for the fan to push hot air through. The ECO ON/OFF switch toggles a power saving mode that turns on the fan only when the power supply needs additional cooling. The fan is pretty quiet and I can’t hear it over the noise of the other fans in the system.

After about 30 minutes of routing and re-routing the cables, I got the power supply installed. Installation was pretty easy. The cables are all labeled, so there’s no guess work about what cables are used where.

Turned the power on and everything came up without any smoke appearing. The cable routing is pretty messy right now. At some point if I get motivated enough, I may tear everything apart and re-route everything to make it look nicer (the insides need a good cleaning anyway). For now, everything works and I’m happy to have an operational system again.

Time for a new power supply

After nearly 6 years, it seems the power supply in my computer has decided to go flaky.

The problem started about a week ago when the computer abruptly shut down on me. After a few seconds it powered back up, and didn’t happen again for a while. Then the sudden shutdowns started to become more frequent. Sometimes the computer would stay running overnight, other times it would shut down 3 or 4 times in rapid succession. It would stay running for a few hours, then boom. Other times it would be up for a few minutes, then boom. Frequent but intermittent.

Primary suspect was the power supply. I reseated all the cables going from the power supply to the motherboard and wiped the BIOS, but that didn’t help things. Then I noticed the main power switch on the power supply was broken and didn’t toggle on/off anymore. Seems like a good candidate to cause such problems.

While the power supply was the main suspect, I wasn’t able to rule out other problems too like something bad on the motherboard. Fortunately someone in the Charleston Tech Slack had a couple of 650W power supplies he was willing to let me borrow. They’re smaller than the 800W supply currently in the computer, but 650W is enough to run things.

Disconnected the old power supply from everything and connected the loaner. Since the power supply is just a loaner, I didn’t bother with putting it in the case.

Computer’s been up and running on the loaner power supply for a few hours now with no issues so far. Compared to what the computer had been doing before, that’s a significant improvement and a good sign that something in the power supply is faulty. I’ll keep it going for a couple more days to see how things go, and if everything’s ok I’ll order a new power supply to replace the original one.
