AMD Overclocking Guide

TweakTown's AMD Overclocked Box


To show you all out there we practice what we preach, we have setup our own overclocked AMD Athlon box to show just what you can achieve with some cool results from overclocking AMD Athlon/Duron processors.


The AMD box consists of an ABIT K7T RAID, we add to this a sweet AMD Athlon 900 which we were able to get to 1060MHz (10.5x101Mhz). we used Kingmax PC150 SDRAM at CAS2 at +PCI Clock. We used a 1.85v core voltage to obtain this high a speed. We also used a Visiontek Geforce2 Ultra 64MB DDR video card overclocked to 300Mhz core and 515Mhz RAM to obtain best results. For the cooling side of things we used 2x80mm Dick Smiths (Australia's Radio Shack), these were positioned at the front and rear of our Itan ATX full tower. 2x60mm fans were used on the side panels which were modded with a Jig Saw and Tunkstan Steel Panel blades, these were positioned right over the CPU for maximum cooling.


Processor: AMD Athlon 900Mhz @ 1060Mhz


Memory: Kingmax PC150


Motherboard: ABIT KT7 RAID


Video Card: Visiontek 64MB [email protected] Ultra (300/515)


Operating System: Windows 98 SE


Video Drivers: Det 3 ver 6.49



With out system running all this we got a cool 8867 3Dmarks. We only lightly tweaked the system to achieve this but with a lot of more time and effort we could have squeezed a lot more out of it. Its all dependent on the components.




The AMD K7 based processors are by far the "easiest" and "safest" to overclock. What we mean by this is that you have a choice of overclocking. You have multipliers, FSB in bios or FSB via software. Overclocking by multiplier takes all the effort of finding ram, video card and PCI preferables that will handle the overclocked bus speeds. That way if the system does not like the overclocked speeds you can then tell it's the CPU and not another device in the computer that is locking up due to the overclocked speeds. Just a few reminders of overclocking. 1) That if you choose to overclock you will break the warranty on the CPU with the manufacturer (whether it be Intel or AMD) so if you do manage to melt the core the CPU have become the most expansive key ring you will ever have. 2) What works from some may not work for others, some people may be able to get their CPU over 1Ghz while you can only get 50Mhz more, this is the price you pay but it can be a worthwhile one if you get a top performing CPU. 3) Always use common sense, most disasters that happen to CPU's happened cause people trying to overclock didn't use any common sense.
