Keegoid's Computer Benchmarks

Building the fastest possible computer on a budget is always a fun challenge (for me). I have to weigh performance vs. cost for each and every component. One benefit, it allows me to spread out the purchase over many weeks compared to buying a complete system in the store. I usually bundle all the components with shipping costs into one checkout to save on shipping, and then I can buy everything else with free shipping as funds become available. I recommend starting with the case, this way you can add components into it as they arrive and check that they fit. Much easier to send something back sooner than later, especially for components that have limited return periods. You may also run into a problem you didn’t anticipate that forces you to go a different direction. It’s best to discover that before ordering everything.

One of the factors that contributes greatly toward my purchase decision is the overclockability of a particular system. After doing a lot of reading, I learned that Intel’s Core i5-750 (LGA 1156) on many P55 motherboards has a sturdy overclocking range that can yield a good deal more performance at a lower price than Core i7 processors on Intel’s X58 platform. Tri-channel DDR3 memory needed on the X58 platform is also an expensive endeavor which swayed me further toward P55.
Sometimes you have to spend money to save money. I not only chose a case that is renowned for it’s ability to move a large volume of air quickly and quietly, I went all out on air cooling! I decided to go air over water for the CPU since the incremental benefit of the water cooling wasn’t high enough in my opinion to out way the cost of not having any cooling for surrounding motherboard components. Especially considering that the water cooling system is more expensive.

Having a system that can consistently provide more cooling capacity to keep the CPU temp down under full load, and also the surrounding motherboard components is a must if you want a stable overclocked system.
After some careful tuning of voltages and frequencies and lengthy torture testing that took many days, I was able to achieve a 50% overclock with an acceptable level of risk to the components. The torture tests simply tax the system to it’s fullest for many hours to determine if the overclocked components will produce any errors. If not, the system is deemed to be stable (enough).

Now that the system is stable, I can run benchmarks to measure what kind of performance has been achieved. This is the really fun part. If you’ve done a good job on the system build and overclocking, you get to see what it can do and compare it with other systems that likely cost much more!
If you know of any good free benchmarking tools and places to post scores, I’d love to hear from you in the comments below!

Cloud-like storage via Pogoplug

Wow, I can’t wait to get one of these and turn my external hard drive into a cloud storage system. It’s cloud-like storage without the cloud storage costs and uploading of files hassle.

I love that the people you choose to share files with can access it like a local drive on their computer! Even computer geeks like easy.

I see this being very useful for graphic designers, photographers, or anyone that deals with sending large files to clients that are too large for email. Good riddance to mailing DVDs. :)

This is the old version 1 Pogoplug, so make sure to buy the new version 2 device since it’s much improved and comes with four USB ports:

DisplayPort 1.2 enables higher resolutions and cable consolidation

By the end of 2010, we should start seeing computers and monitors with the new DisplayPort v1.2 interconnect. Anything that allows me to have a better image and clean up the mess of cables coming out of my computer is a-okay in my book!

At the rate that demand for bandwidth is increasing, I think I’ll put in PVC tubing in my walls so I can easily pull through new cables as technology continues to improve. Then I can get that 4K projector I’ve always wanted! Yeah right, keep dreaming Keegan.

Here’s a good post on this topic at geek.com.

Gmail Labs I use and love

If I didn’t use many of these Labs, I might be inclined to think Gmail wasn’t very functional (read: Gmail sucks). Thanks to the work of many enthusiastic people however, Gmail Labs do a great job of improving the usability of Gmail to the point where I was able to replace my desktop client completely. Goodbye crashing, freezing, slow Outlook!

You can find the Labs in Settings —> Labs.

I’ll try to keep this list updated as I make changes to my preferred Labs and as Google updates them. Really the Labs are beta features for people to test and work out bugs before Google decides if they are worthy to become a permanent part of the base Gmail app.

This list includes all the labs I use:

YubiKey with TrueCrypt and LastPass

If you’ve used TrueCrypt to create an encrypted volume on your computer, you know how annoying it can be to have to remember a strong password. And if you didn’t use a strong password to create the encrypted volume, why even bother?

YubiKey makes it easy to quickly mount the TrueCrypt volume using a very secure password that I could never remember. Also, keylogging programs won’t be able to record your keystrokes if you don’t have to press any keys! The YubiKey is particularly useful if you have to use a public or untrusted computer.

YubiKey also works well with LastPass and many other services like Google Apps.
