Shuttle SB77G5
Posted on: 01/15/2005 06:00 AM

We'll dig right into several screenshots from the BIOS on the SB77G5. This part of the review is generally the least exciting for someone like myself who's no longer fascinated with overclocking. That being said, I'm sure there are plenty of you out there who still look at BIOS features when making purchase decisions.

The Advanced BIOS Features page will look rather familiar to those of you who've used an Award BIOS before. You'll be able to toggle boot devices, enable and disable Hyper-Threading and the processor's L cache. Not much to see here, let's move along to the next screenshot.

The Advanced Chipset Features page will let you toggle the latency settings for your memory. In my screenshot, I'm just setting the DRAM Timings automatically by SPD. Those of you wanting to get more aggressive can switch it to manual and shoot for faster settings, like 2.5 for CAS and RAS.

The third screenshot displays the PC Health Status page which is basically a simple hardware monitor. It lists system and CPU temperature, all the necessary voltages and the current speed of any fans attached to the motherboard. The Fan Speed Control is set to "Smart Fan" meaning the fan spins quite slowly (~1,000 rpm) until certain temperature thresholds are reached. In this scenario, my 3.6GHz P4 ES was running at a relatively warm 59C.


Now for the tweakers out there, I will run through the available overclocking options. If you'd like to get every ounce of performance out of your CPU, you'll be interested in this segment. Let's start with everyone's favorite: vcore.

The list of available vcore voltage settings was quite long. As such, I decided to take a screenshot of the bottom of that list. With the ability to go as high as 1.5875V, I would imagine that you'll be able to sufficiently overclock your LGA775 processor. Since I was quite satisified with 3.6GHz, I didn't attempt to overclock it. If you do, please take into account the heat implications. I wouldn't want any of you to fry a potentially expensive component.

A lot of people don't look any further than vcore adjustments when looking for a board that will be an excellent overclocker. If you're really pushing the front-side bus and memory, you may want to be able to increase the voltage running to your DDR. As you can see, the board in the SB77G5 offers you those tweaks. Additionally, you'll also be able to run your AGP out of spec from a voltage perspective if you so desire.

Last, but certainly not least, we have the front-side bus adjustment. With settings ranging from 100MHz to 355MHz, I think any and all overclockers will be quite satisified. Just punch in the FSB you'd like to try and reboot. You should also cross your fingers and say a prayer that the machine POSTs following the FSB change. It appears as if Shuttle covered all the bases with respect to overclocking.

Now that we've covered the hardware and the BIOS, we should break down my test systems and discuss what benchmarks we have decided to run for the review.
