Now that AMD has started the practice of locking the multipliers on their latest Barton processors, a lot of overclocking enthusiasts think that this is the beginning of the end for overclocking AMD CPUs. We got our hands on a multiplier locked Barton 2600 XP to test how far we could take these now overclocking limited processors.
Remember not all processors are created equal, and results will vary even with the same type processor.
Test System
AMD Barton XP 2600+ 333 MHz (AQYHA)
Asus A7N8X Deluxe rev 2.0
Corsair PC2700 XMS 512 MEGS
Zalman cnps7000a heatsink
Western Digital 80 gig 8 meg cache.
Arctic Silver thermal paste
Memory timings where set to optimal and DDR Voltage was left at 1.6. AGP bus was locked at 66MHZ.
The first attempt i made was to run the front side bus at 186 MHZ X 11.5 and the Vcore was left at default. The Computer booted to windows and everything seemed to be ok. Various bench marks and stress tests were performed such as Sandra burn in wizard. That's an overclock to 2139 MHz compared to the stock 1910MHZ. That's Just Shy of a Barton 3000 XP! :)
