At 3.0 GHz the multiplier on the AMD 6000+ is set at 15. (200 FSB x 15 = 3000) I feel that this pretty much maxes out the chip and is most of the reason why the 6000+ is not a tremendous overclocker. The max overclock I was able to achieve and just to run CPUZ was 3.525 GHz, FSB 235 x 15, HT4, Vcore 1.550v, NB 1.30v, SB 1.60v and HT 1.3v.
My next step was lowering the multiplier and raising the front side bus, there was no problem reaching a 300 FSB at a multiplier of 12 and which also brought my ram to it's stock speed of 1150. I'm sure if I would have placed a divider on the ram and lowered the multiplier to 11, 10 etc., there would have been much more room to play with. In theory as you lower a multiplier you should be able to increase your FSB endlessly as long as you don't reach the limitations of your memory or motherboard.
What speed was I able to achieve that was prime stable without having to envenom too many volts, lower the multiplier and decrease the HT? That was FSB 230 x 15, HT5, NB 1.25v, SB 1.55, HT 1.3v. At these settings the system was prime stable for 24 hours. Overclocking did make a difference in performance in some benchmarks and in others not enough to talk about.
Getting back to the x15 multiplier, we all remember when the Intel Pentium 4 reached that pinnacle there was no room left for a decent overclock but now the Core 2 Duos that have lower multipliers and increased FSB speeds Intel is all the rage in the enthusiast community. Why? We like to tinker and tinkering is fun, but isn't there a time just to say ok and accept something for what it is? Yes and No. Yes if you just want a computer that is going to perform solid right out of the box, knowing that this is what you are going to get and you can be happy with that. No, if you want performance above what stock specifications will allow a processor to perform, and I think this is where the enthusiast community wins. We put CPUs to the test... we benchmark them, manipulate voltages, remove the IHS and torture a processor to limits even manufacturers cannot believe. This does one thing it gives them the opportunity to rethink and redevelop with all the information gathered so one day they might just have the perfect enthusiast platform available.
