Hi. I think my motherboard is on its last legs. I may get a new one, but I'm happy to keep the current CPU which is a Socket A Athlon Thunderbird 850MHz for 100/200MHz FSB.

I figure I could use the pencil trick to unlock the processor and set a lower multiplier to run it with a higher FSB speed, as these new motherboards support such high FSBs. I gather it'll run with 133MHz FSB, but what about speeds higher than that? I remember reading that the Thunderbirds become unstable beyond 150MHz FSB, is this true? Would DDR ram make things worse? 5x is the lowest multiplier this CPU supports right?

Thanks for help

Well, my old 1.0GHz Athlon Thunderbird didn't like any FSB over 150MHz - that was the highest FSB i could boot into windows$ at.
If memory serves me, it wouldn't even POST beyond 150MHz FSB.

I don't think it makes a difference whether your using SDRAM or DDR-SDRAM - most likely, you won't be able to run a 150MHz FSB stably with SDRAM as only few sticks will run stable at that speed.
QUOTE 5x is the lowest multiplier this CPU supports right?
Yeah. According to the datasheet, that's the lowest possible multi.
