AMD Athlon64 3200+ 32/64-bit Processor Review

AMD Athlon64 3200+ 32/64-bit Processor Review  - PCSTATS
Abstract: Tired of being an "Intel clone," AMD's goal became to set market trends, instead of just following the lead of chipzilla.

Overclocking, it's all new now

Overclocking the Athlon64 is very much like overclocking a Pentium 4 processor now that AMD has multiplier locked the processor. It may take a while for enthusiasts to get use to the whole process.

Because the memory controller and clock generator are built into the core of the processor, overclocking the chip can be a lot more tricky as memory controllers tend to max out very quickly. Also not much is known about the integrated clock generator and about how high it can go.

On a side note, before we get into the numbers I think it is important to mention that although we have used the term "FSB" in the following pages, the Front-Side-Bus isn't really applicable anymore to the Athlon64. As an AMD Representative puts it; "The 200MHz clock generator feeds the components of the motherboard (including the CPU), but it is not the speed of the CPUs interface to the memory controller or to the chipset. The old term FSB has always represented the speed at which the processor moves memory traffic and other command and data traffic to and from the chipset. Because the memory controller is located on the processor die, that memory subsystem traffic no longer has to go through the chipset or CPU-to-memory calls. With Athlon64 processors, the speed at which the CPU and memory controller interface is full processor frequency - the speed at which the processor and chipset communicate is dependent on the chipset's Hypertransport spec which can be at speeds of up to 1600MHz."

As the motherboard BIOS we tested with still uses the term "FSB" to facilitate overclocking, we will continue using it for the moment as well.

In any case, using the stock AVC Z7UB30 heatsink we started to raise the clock speed of the motherboard. At around 210 MHz "FSB" we ran into a few stability problems, but raising the memory voltage to 2.8V fixed that. At 221 MHz "FSB" we again ran into memory related issues and had to run the memory at 6:5 memory divider (DDR333 mode). We were a bit surprised that our Corsair XMS3500 CAS2 DIMM's maxed out so quickly as they easily run at 225-230 MHz "FSB" in dual channel mode with the most aggressive timings on nForce2 motherboards. Perhaps the Athlon64's integrated memory controller was starting to max out?

With the 6:5 memory divider enabled we seemed to hit the wall at 223 MHz "FSB." No matter what we tried we couldn't get the processor to run any faster. Another interesting thing that we discovered no matter how high we set the Vcore on the motherboard, the voltage the processor would only receive 1.5V.

The first attempts at overclocking the Athlon64 3200+ showed us a 10% increase in speed, and from such a large chip that is pretty good. And now, the benchmarks!!
