Intel D865PERL - Page 5

..:: D875PBZ “Bonanza” BIOS & Overclocking ::..

The BIOS that comes with the D865PERL is that of an OEM system in layout much like what we saw with the PEBT2 and PBZ, exactly the same in fact. This BIOS offers up all of the same options and tweaks as did these two other boards, including the limited overclocking options that we have seen Intel begin to offer. The main window of the BIOS houses the information about the system such as RAM, FSB, CPU speeds, Hyper-Threading support, and other miscellaneous information such as this. The available submenus that we’ll be interested in for today’s review are the Advanced and Boot menus.

The first of two menus of great importance to us would be the advanced menu. This is the main menu that we’ll be working with as it is home to the limited overclocking options, tweaking settings for memory timings, and other items such as these. When we enter this window, we’ll see a nice listing of submenus listed such as peripheral configuration, boot configuration, chipset configuration, hardware monitoring, and fan control. We’ll primarily be interested in working with the submenus that I have listed above for today’s review.

The peripheral configuration submenu is where you’ll want to head in order to enable or disable the serial port, parallel port, onboard audio, and the onboard LAN. If for some reason you would need to enable or disable any of these items built into the motherboard, this is where you would need to go to do so. The hardware monitoring menu should be self explanatory. Here you can monitor your system temperatures, fan readings, and voltages to make sure they are within proper specifications for your system. The fan control menu is home to the system’s own fan RPM controlling system. Here you can choose to enable or disable the option to have your fans either slow down when the system is at low temperatures, or for the fans to remain completely off if temperatures are low enough. This is surely a welcome item for those of us who hate the noise several cooling fans can bring.

The main window that performance users will be interested in is that of the chipset configuration submenu. Here we come across some interesting options, the first of which can be found at the bottom of the menu that control the various main memory timings. As you can see we have control over the CAS Latency, RAS Act. to Precharge, RAS to CAS Delay, and the RAS Precharge. The settings viewed in the image above are the fastest settings available. There is an option to set the memory timings to a setting of aggressive if you don’t know what you’re doing when setting the memory timings. The other main item of interest would be the Burn-In mode submenu. This is the latest addition to the BIOS and it allows for both minor overclocking and even underclocking. This will allow for up to a 4% gain in processor speed, and a 2% drop in speed.

Overall the BIOS that comes with the D865PERL was what I had expected to see, especially from our previous experiences with the PEBT2 and PBZ. When we first reviewed the D845PEBT2, we were excited and surprised to see Intel taking a slightly more lenient stance towards the performance users with some of these new BIOS options. Now that we’ve seen the board, the features, and the BIOS, let’s get to the benchmarks and see just how well the D865PERL and Springdale-PE chipset perform!
