More Current Draw raising the FSB or Multiplier on an AMD Tbird??

[Southpaw]

Dont have one yet, but just curious which would be higher on the processor itself...

Lets take example:

TBird 750 --> 1Ghz via 10X100Mhz
versus
TBird 750 --> 1Ghz via 7.5X133

I suppose the one that gets hotter is drawing more if all you had to index it by was temps...

Just wondering if any studies had been done...

thx

Good question!!! I'm sure your not going to see an official study from AMD since they discourage overclocking. But since you get more work out of a higher fsb, I am going to go out on a limb and say its gonna run hotter(i.e. more wattage), higher fsb definitely runs the Northbridge on the KT113A hotter.

Im pretty sure they operate at the same tem. the mobo and memory might get a tad hotter though.

I cant really see AMD "discouraging" overclocking. Their new 1.2ghz's are unlocked, and they are teamed up w/ kryotech to bring massively overclocked computers @ -40 Celcius.

Kyrotech still in business, their website is up but it only has junk listed for future projects. (A WOW 1.25 GHZ system) Air cooled go faster than that now, so I kinda think they took a dump. I know from letters to AMD that they void warranties on processor's for overclocking, so um maybe they encourage it, so they have to do less support. :Q 😉 😎

I dunno about Kryotech, but the current draw on the chip is interesting. I would think that the multiplier overclock would draw more current (generating more heat) than the FSB clock though not by much. We may be splittin hairs here. The multiplier overclock would be causing the cpu to execute faster while the FSB overclock would actually be causing the memory to run faster, although the CPU should have no trouble keeping up with faster memory since your particular CPU has a 133mhz FSB bus (266DDR). I'm trying it both ways - and the heat question is why I intend to do that. Right now I have it at 10X140 (Iwill KK266-R) with the same processor you have (1.2g266mhz). I'll post back when (and if) I determine anything.
