Soltek SL-75DRV4 - Page 6

..:: System BIOS ::..

The SL-75DRV4 comes along with a fairly nice Award BIOS. The BIOS is divided up into the usual sections, Standard CMOS Features, Advanced BIOS Features, Advanced Chipset Features, Integrated Peripherals, Power Management, SmartDoc Anti-Burn Shield, Frequency Selections, and of course the Load Optimized Defaults options. Most of the options made available in these different sections are well known so I'm going to stray away from writing about them. First off let's take a look at the Advanced Chipset Features section.

Once we entered the Advanced Chipset Features section, we came across three sub-sections dedicated to DRAM settings, AGP settings, and PCI settings. If we enter the DRAM section, we'll come across the option to adjust the Clock, Timing, CAS Latency, Bank Interleave, Burst Length, Queue Depth, Command Rate, System Performance, and DDSkew Level. The optimal settings that I found are shown in the picture above. This is the only real section you'll want to pay true attention to as only the most knowledgeable techs should toy around with the AGP or PCI settings.

The next section we'll take a look at is the SmartDoc Anti-Burn Shield. This area allows you to set a temperature at which you will be warned of a dangerous CPU temperature, and another setting at which the system will immediately shut itself down within three seconds.The available settings are 60, 65, and 70 degrees Celcius. There is also an option to select a dangerous low, and shutdown speed for your CPU fan. If the fan reaches a certain speed you'll be warned, then if it continues to drop, off goes the computer. This is a nice feature that more and more manufacturers have been including in their BIOS'.

The last section that is very important to the overclockers is the Frequency / Voltage Control section. Within this section is the option to run RedStorm Overclocking, which if you remember I could not get to work, the CPU VCore selection, and the option to adjust the FSB. The different skew adjust rates didnt change performance at all from my testing so I chose to leave them at the default of Disabled. The CPU clock can be adjusted in 1MHz increments, along with the VCore which can be adjusted in .025V increments.

..:: Overclocking ::..

With the SL-75DRV4 I was able to achieve the same stable FSB of 150MHz as I achieved with the Asus A7V266-E. This is more than likely due to the fact I am using a locked AthlonXP in the test bed. One of these days I really have to pick up a good unlocking kit and unlock this sucker. I was able to achieve the speeds with a VCore of 1.85V, and a DRAM voltage of 2.7V. I highly recommend manually adjusting the different settings in order to achieve maximum stability. As I've already mentioned I could not get RedStorm Overclocking to work, so I'd stay with the good old manual way of overclocking. Besides, what overclocker wants the board to do everything itself? That just kills the fun of overclocking! Now that we're more than familiar with the inner workings of the SL-75DRV4, let's get to the benchmarks!
