 The Hot-687
Shuttle's Lean Mean BX Mobo

Ok, with 3 Shuttle reviews on the books here at HotHardware, two of the socket 370 variety, the latest 370 board weighs in at a svelte (I actually looked the word up) Micro ATX weight. Our test unit lacked the hardware monitoring chip (available as an option) that lets you keep tabs on cpu/system temp, fan speed etc... But hey, so you have a choice. This board did not give up the overclockage easy but with some help we got the goods. Read on for the um... skinny on our latest board from Shuttle.

If you're like me and you have a choice between CPU voltage changes via the BIOS and jumpers, you go with the former. Jumper jockeys rejoice, you have plenty to play with here. A jumper of note is JP5 a.k.a. "Factory Reserved". You need to remove this jumper in order to overclock the cpu. The layout is straight forward and the pudgiest of fingers will have room to work. The power connector is nicely moved out of the way of your cpu etc... Pretty much standard practice for Shuttle. Three fan connectors with monitoring capabilities are positioned properly on the board. One near the power supply, another near the CPU and AGP Slot and, the third, just close enough to the fan at the front of your case. As stated earlier, fan speed/temp/voltage monitoring are an option for this board.

Once again, the 687 holds its own. Not a total speed demon mind you but no slouch either.


A word on Audio Quality

The addition of on board sound saves you a slot. The sound quality is excellent. The 3D Positional Effects were convincing. Shuttle also threw in "EZ-Audio" with this board which is basically a CD Player Wave, and MIDI Controller to replace the windows default system. This software as well as Windows 98 compatible drivers are on the included CD.

Well my overclocking brethren, I can say without a doubt. I have HAMMERED on this baby for quite some time, playing (and kicking some butt I might add) copious amounts of Q3 Arena, Unreal etc... With temperatures in the upper 80's in the testing area, this board was just soaking it all in at 463MHz!!!

The Final Word?

Price,Price,Price... Stable,Stable,Stable... Even without a voltage adjustment, we were able to achieve stability at 463MHz. It comes with kick-butt sound chip built in and a well laid out design.

Jumpers-a-plenty... It's Micro-ATX design leaves it a little light in the available slot department. The presence of a voltage adjustment may have made 504MHz possible with this board. That's all, we'd add another downer, if we could think of one...

We give the Shuttle HOT-687 a Hot Hardware Temp-O-Meter rating of...

85 Hmm, spicy little chili peppa!
