How many of you have tried Overclocking the new celerons

PIII 700 @ 931 (1.8 V), Asus CUBX, 256 MB Siemens PC100 @133 (2-2-2)

Drystone 2517

Well slapped a new heatsink on and bugger it it still won't have it at 133mhz bus. Never mind it was one of the earlier 650. I'll leave it running at 124 bus and 806mhz.

[Rice-Boy]

These are nice o/c u guys are doing..

I'm planning to get this system tell me what u guys think.

Celeron 600 o/c to 900? or higher
256 PC133
Abit BE6-II
Matrox MAX
2 30gig maxtor 7200

How much do u guys think i can o/c this baby and would my Matrox Max be able to handle bus speed that higher than 100?

Currently i have the 300a and o/c to 450 anything higher the Max would crash on me.

I doubt that it's your Max rather you've just reached the Cpu limits. My G400 (None Max) is running quite happily at 82.6 mhz. Many have got it running at 89mhz without problems although some have had to force agp x1 to be stable.
Don't forget to pay attention to cooling as this is another way of causing the processor to bomb out. Cpuidle is great for win98 you don't need it for win2k as theres already a cpuidle process built in. These programs make quite differance to Cpu tempature.
The 566 seems a better bet than the 600 for overclocking no doubt due to it's locked muliplier. It'll say you a little bit of cash as well.

Rice-Boy, I couldnt help but notice that you were mixing a celeron 600 on a BX board with PC133 ram. If youre going with standard air-cooling, I think you can improve on this combination.

Now, if you take a look back, we reccommend either the 533 or 566 chips because of the higher resultant bus speed. Given that the average overclock of all our Celeron IIs is in the 900MHz range, at that speed your Celeron 600 would be running on a low 100MHz FSB...choking the poor processor, and making little use of your PC133 ram's potential.

Your ram can handle it, and the G400 can handle high AGP speeds, so why not go for a celeron 533 or 566 instead?

Just for confirmation what is the highest AGP speed the G400 Single VGA can handle and what if any are you overclocking it at and any extra cooling!?!

Thanxs!

g400's are usually very good at high fsb/agp speeds

I know I am going to sound piss-weak in this discussion... here it goes:

I want to get a Celeron II, and overclock the FSB to at least 100MHz WITHOUT EXTRA COOLING. Which chip should I get?

I have read briefly though all your posts, but it seems that all of yous are using other types of cooling.

(I am in Sydney, Australia. If anyone knows where I can get proper CPU cooling here, please notify me. I don't want to buy overseas stuff because it's hard to exchange if something goes wrong.)

[Maggi]

Welcome aboard James !



I see you followed my link ...

Anyway, all I did was adding a 2nd fan to the standard Pabst HS/fan combo that I purchased along with my Cel-566.

I suggest to read this thread closely as you will find plenty of tips how to get it stable @ 100MHz FSB ...

Mine stabilized @ 112 FSB after I upped the VCore to 1.85 and repositioned my 2nd fan.

Cheers,
Maggi

One word of warning once you started overclocking you always want that bit more. I keep getting these dreams saying one giga.

[Maggi]

What MoBo do you have ?

Post some system details and we'll see which CPU should be fitting best ...

[tong_james]

Yea, thanks maggie. This should discussion should help me out heaps.

I haven't been fiddling around with cooling much- how do you stick a second fan onto the HS? Doesn't the first one block the top of the whole thing already?

I have a BE6-II, 128MB PC133 SDRAM, and a generic slocket at the moment. Should I get a new slocket as well? (I'm trying to minimise cost...)

[Maggi]

morning James (or is Tong your first name? sorry if I mixed it up )

anyway, already I described how I attached a 2nd fan, but in case you missed it:

Imagine the CPU being plugged into the mobo vertically ...
I used simple screws to attach the 2nd fan on the lower side of my HS, so that it blows directly upwards.
the combination of both fans create an air-stream that pumps the heat directly towards my powersupply and that one sucks it out of my case, exhausting it to the rear of my tower.

Your BE6-II should offer you VCore settings of 1.8V which seems to be a minimum for guaranteed stability in the higher clocking ranks. If not, your slotket should provide those voltages, hence you should be settled for a start.

About the CPU ... make sure it is manufactured in Malaysia (MALAY stamp on either the box and the CPU itself), as those seem to offer the best OCabilities.

Reading that you have already PC133 RAM let's me suggest to grab a Cel-533A (the A lables the Cel-II, without that letter it is an old P2 based Celeron) and crank it beyond 100MHz FSB !!!

If you're lucky, you could make it up to 133MHz FSB giving you more than a GHz ...

Before you start going beyong 100MHz FSB, make sure to disable UDMA in your MoBo's BIOS !!!
(will save your IDE disks ...)



To sum it up:[*]attach 2nd fan (can be ripped off an old CPU for example)[*]disable UDMA[*]set VCore to 1.8 volts[*]set FSB to 100MHz in your BIOS

if it boots without probs, reboot to BIOS and up the FSB further ...

I'd personally try 124/4 (31PCI) as 2nd setting when 100MHz succeeds, because it'll either won't POST at all - blank screen, no BEEP upon startup - and resets the bus to 66 MHz or it might post but fails loading Winblows ... if it boots into windows, make some CPU intense tests like UT, Q3, SETI or any CPU stress benchmark, when no probs occur you should goto 133MHz FSB and see what happens

In case it won't boot at 124/4, try 112MHz and so on ...

Now go ahead and give us feedback about your success.

Cheers,
Maggi

[tong_james]

How do you stick the fan in such an awkward position? Don't you have to funnel the air into the heatsink?(I don't know how big the heatsink is)

I am planning to buy the Celeron II in 2 weeks- sorry.

I am just doing my homework to make sure I get the right chip, and to make sure I don't kill it when I get it.

[The PIT]

Talkign about cooling has anyone tried a globalwin 802 case?
