I am seriously considering ordering a Celeron 300A next week.
But I have a few questions...
All related to overclocking to 450. FWIW I studied Computer Science
in University for several years (and finished my degree). I also have
a P150 overclocked to 166. Tried 180+ but wouldn't boot or had system
errors. The point being that I am not new to this computer thing.
I am either getting a Celeron 300A or an AMD K6-400
1) What motherboard should I get?
2) What are multipliers and bus speeds typically to overclock to 450?
What should I be looking for in a motherboard?
3) If you have a 300A overclocked to 450, have you had any error
messages while running Win95/98? When I tried running my P150 with a
75 bus speed I got a lot of error message--in fact my system was
outright unstable. When I tried 66*3, it wouldn't boot up at all.
4) Is the Sound Blaster 64 PCI supported in Grand Prix Legends?
5) Any problems with overheating? Should I put the computer unit
into a refrigerator? :))
6) Any other advice?
7) What about the Celeron 400?
Overclocking a Celeron 300A for sims
A user planning to buy a Celeron 300A asked about overclocking it to 450MHz. Replies recommended the Abit BH6 or BX6 with BIOS voltage control and noted the BX6 may need a BIOS flash, while a few questioned whether overclocking belongs in the group.

Abit BH6. It has BIOS options for bus speed and core voltage. I'm currently
running my 300A on it at 450. The other popular board is the ASUS (P2B??).
See above. The celeron 300A is multiplier locked to 4.5x, so you run it at a
100MHz bus speed. Set the AGP/BUS setting at 2/3.
You can even try running it faster. I haven't.
At first, very much a "yes". With a couple of days burn in running at lower
bus speed, and/or running in DOS at higher bus speeds, it now takes 450 with
the std 2.0V. No more errors. Excercise that puppy at lower speeds!
???
Some say yes. But if you are able to run at the normal 2V, I doubt it.
Patience, and luck. At least back up your registry (MS site, look for
cfgback.exe). I'd recommend backing up your entire drive. I had a couple of
scary registry errors and one FAT problem. But they seamed to heal thyselves.
Doubt it can be much overclocked (actually over "bussed") since it'll be
clock-locked to 6x and 6x100 is seriously doubtful. You can probably run
6*75, or hope for 6*83. But they are new so I don't know (nor care since I
just got my 300A).
I bought my 300A "boxed" from NECX for $100. That includes the std heatsink
and fan. If you get an OEM one cheaper, you still need a decent sink/fan
combo. In that case, everyone says get the thermal compound from Radio Shack
to give a better thermal path from chip to sink.
Some say that the "boxed" are better, but this is most probably anecdotal.

AnandTech recently put up a good article that got to the bottom of which
300a's are good for overclocking and which aren't. Go to
http://www.anandtech.com and look for the story called "The Celery Report:
Overclocking the Celeron."

Oops... make that bus speed 100, multiplier 4.5X for 450.
Sorry about the typo...

Does ambient temperature matter when overclocking ? I'd be interested
to know anyone who has succesfully overclocked 300A to say a 450
(without frying the processor) who lives in the tropical region in
which the air temperature normally ranges from 31-35oC . How did you
manage to do it ?

B Hisham
What, no air conditioning?!
With a dual fan/heatsink, you should be ok. The humidity in a tropical
location increases the cooling effect of the heatsink through condensation
and evaporation. Moisture combined with a fan in a small warm room is
called an air conditioner. In some areas they're called "Swamp Coolers."
Not as effective as a Freon-based refrigeration A/C unit, but much cheaper
and very simple. Your processor should run cooler than one in a dry place.
Your only worry should be what the moisture will do to the electronics. You
may get as little as half the life expectancy as a dry climate(without
dust).

How did you >manage to do it ? >regards, >B HishamThe 300a is the choice for overclocking - it appears that you have a very
good chance of running it at 450. The Abit BH6 is the only board to get -
if you can find one in stock somewhere right now. Boxed Celerons can be
found right now for as low as 70.00.
Don't even consider the K-6, it is not good for games unless the game has
a 3D-Now instruction set. Also, the Super 7 mobos needed to run this chip
had a lot of problems and may still have them now.
It is not uncommon to have to step up the core voltage to get to 450.
This means cooling is an issue - but a good heatsink fan and perhaps an
extra case fan will probably suffice.
There is a company called Minotaur technologies- www.minotaur.com - that
will sell you a 300a that has been pretested at 450 for $20.00 more than
their standard price. As of yesterday, that was 79.00 untested, $99.00
tested. I have not bought from them, but they are well regarded at
www.resellerratings.com. However, check on their return policies - they
may not take CPU's back. (If you catered to Overclockers, would you?)
I am about to take the plunge myself. Wish ATX cases and PC100 ram were
cheaper!

The Abit BX6 is *just* as overclocking friendly as the BH6 (also with
the softbios for easy overclocking). The only real difference is the
number of ISA, PCI & memory slots.

Yes, I believe (may be wrong) that the BX6 has one more mem slot, one less
PCI?
The BX6 came out before the BH6. There has been a fair amount of speculation
and/or anecdotal info that points to it *perhaps* being less oc friendly for
some reason or other. Again "perhaps" due to it being older and less
refined?? I opted for the BH6 due to this.
Isn't there ar newsgroup that would be more suitable for the discussion of
overclocking [voiding the warranty of the chip] processors?
Yep, it certainly is, why would I want to change it?
And, yes, I've heard most of the usual jokes (gags!), but hey, if you
think you have an original one to offer, go for it.....

Yes there are newsgroups that deal with overclocking & also news groups that
dealwith building your own PC's. But most people that are asking these
questions on this newsgroup are looking for "real world" reports on what it
does for their Sims.
Yes overclocking is DANGEROUS. It will make your hair fall out, your ***s
dry up & fall off & all other kinds of "Bad Things Man". {this is a disclaimer
so if you blow yourself up it's not my fault}. The reason we overclock is to
get PII 450 performance from the lowly Celeron processor.
But if you want to take the risk of pushing your processor to the limit, YOU
WILL get faster frame rates & a more enjoyable *** experience.
The best thing to do if you want to overclock your machine is to do some
research. There is a lot of information out there on overclocking eberything
from a P120 to the new Celerons, K6-2s, & PIIs.

Yep loads of em, but there are not *that* many o/c'ing threads here to
complain about are there? and most of em are referring to how it
improves performance in games/sims as well, so it is slightly relevant
to the group. You could try filtering out any unwanted message types?

The BX6 does'nt support 124MHz bus.

Isnt there also some sort of a BIOS issue with the BX6? I just got a BH6

John,
I'm curious as to why you replied "no" to the Celeron 400?
I just put together a machine using the Abit BH6 and C 330A and am happy
with it so far, I am going to be doing a second computer soon and was
considering a C 400 with another BH6.
What are the problems with the 400? Is it bus locked as well as
multiplier? I was thinking it should be capable of around 600 Mhz?
Thanks
Trev
The odds of successfully overclocking any PII/Celeron to 600MHZ is extemely
low, maybe not even possible. You might get 500MHZ out it and less likely
maybe 550MHZ range. The other problem with overclocking Celerons other than
the 300A is using buss speeds above 100MHZ. Most if not all of the current
MB's only give the correct AGP/PCI buss speed at 66, 100, and 133MHZ which
can lead to problems with some devices which use those busses. To my
knowlege the first Intel proccessor that will be <though maybe not
initially> designed for 133MHZ front buss is the Katmai <sp?> The core of
the new Celerons is still the same one being used in the others.
If you intend to run the C400A at it's intended speed, or possibly 112MHZ
front buss you should have no problems.
Dan.

I thought the C400A had a 6x multiplier for a 66MHz bus. Thus, 6x100 = 600MHz
is highly unlikely to work so 112MHz is out of the question.

The BX6's original BIOS didn't support the Celeron 300A. Pretty much
all the BX6s out there now should have the upgraded BIOS, but if you
bought an old one that had never been flashed, you'd have to flash it
(using a P2) before it would work with a 300A.

(6x) . I just ordered a 366 mhz model that I hope to push into the
550 land.... will let the group know.

I stand corrected. :)
I've got my on the 366's as well. Think I'll wait for guys like you though
to see how well it overclocks, and % of success. <G>
