"Easy" assuming your comfortable with voiding the warranty and have good soldering skills. You can overclock any 133 bus mac to 166 relatively easy. Go to the tweaking and case mods section of xlr8yourmac.com.Originally posted by onemoof
Assuming that the Dual 867 uses the same mobo as the other PMacs wouldn't it be easy to clock the bus back up to 166 MHz? I assume it's probably just downclocked to sell people up to the midrange.
Bus x Clock multiplier = CPU speedOriginally posted by GeeYouEye
Correct me if I'm wrong, but doesn't increasing the bus speed make the clock go too fast (ie overclocking 100-133MHz makes the clock rollover 1 minute every 40 secs)
So if I understand this right the 867 chips will end up running at a little over 1GHZ?Originally posted by mc68k

Overclocking the bus overclocks the components in the system, too.
No. You can upclock the old PC133 busses to 166 and it still recognizes the mem fine. Same with my old mac's 50 mHz bus. No problems there. The 2100 RAM is on a different bus than the system bus.Originally posted by Sepulchre
But then would the PC2100 Ram be too slow?
So why does apple spec the PC2700 for the 166 bus and PC2100 for the 133 bus, just to get the most performance out of it?Originally posted by mc68k

Thanks, but no thanks. I only do overclocking through the dips on my XLR8 card. As for soldering/desoldering things, that's not my cup of tea. I've got better things to do w/my time.Originally posted by topicolo
Jeez, you guys are such o/c newbies (except you ddtlm. You seem to know what you're talking about. What have u got there? a watercooled rig? a peltier?) Try visiting some pc o/c sites like [H]ardOCP and you'll learn a LOT. (a lot of the theoretical stuff applies to macs too.)
I feel I must apologies for being such a Virgin at this Over clocking subject, as I have never found then need to over clock my Mac it is not a field in which I have ever sought to increase my understanding.Originally posted by topicolo

"im somewhat sure that its just a jumper setting. screw the warranty, buy it at compusa and get their warranty. it covers it. if you are gonna screw with your computer hardcore, buy it there and get the service plan."
yeah but you go thru hell gettingcompusa to live up to the warranty they sold you. Their money comes from selling you this high priced warranty, they stall and try to keep you from using what you paid big money to buy.
In other words don't get teh comp "TAP"
