Celeron 600 O/C... How high?

[The Coolest]

My friend got hooked on the O/Cing stuff and now he wonders how high can he get his celery to run? we O/Ced it to 675 with no raise in CPU temp in Prime95 Torture mode, its always around the 50s and he's getting new HSF soon. So what do u think?
I don't really know Intel CPUs but his multiplier seems to be locked? could it be?

Yes, Intel multipliers are locked. You raise the bus speed to get more mhz from the cpu.

Better cooling is in order. If 50 is in celcius, then that is indeed too hot.

sorry to sound stupid.. but what the multipliers are?

The temps are indeed in C° though his comp has been very stable, when overclocked to 675 (was 66 * 9 , now 75 * 9) the temp didn't raise. he's got a Gigabyte MB and uses the the HM from the mobo CD...

And how high can he get that comp with a better cooling?
1 last question: What's the Max temp of Celerons like his?
My t-birds is 95C...

For any chip, AMD, Intel, above 50 is decent if you're not planning on overclocking and _bad_ if you are overclocking. Get a much better cooler on that thing. Don't pay heed to what the guys at Intel or AMD say about max temps...though you can check out the links on the CPU database. The 600 is a good overclocker and, with good cooling, can hit 900 fairly easily. My cC0 Celery 633 hits a gig easy (not running there since my board can't supply enough voltage)...but you got to keep it cool. Idle at 33, load at 44. With even something like a stock thermoengine, full load will hit 50 some and it will be nowhere near stable. Cooling cooling cooling!

50oC is stupidly high at 600-675mhz, lets just say that at that speed my 600 only gets to about 26oC (full load). If you can keep it quite cool then you shouldn't have any difficulty getting to 900-1000mhz, a couple of case fans and at the very least some heat transfer compound or maybe a better heatsink is in order.

Hi ToxicRat,
There isn't stupid question, is stupid don't ask ;)
About your question, well, the speed of a Cpu is given by the multiplication of the internal chip Multiplier for the Fsb (the System Bus), for example a Cpu like a Celeron 600Mhz use a Fsb of 66Mhz and a multiplier of 9x: 9x66=600Mhz, now considering that the Multip, is locked and unlockable, the only way to OC(OverClock) a chip is rising the Fsb.

I hope it helps you ;)
