Celeron 366 at 550 ... Manufactured when, and what success rate?

Just wanting to know what manufactured date and what success rate these 366's @ 550 have. Is it the same sorta of case when the 300a's were released and able to hit the 450 mark on nearly every occasion? I have an abit BH6 and one of these 300a CPU's (Costa Rican) and it hits the 450 mark, but nothing more. Would it be worth tracking down one of these 366's and a good converter card (Perhaps and Asus one?) and clocking it up to the 550, or is it too risky when you consider that if it dont like the 100 mhz fsb, the best I could do with it would be 83fsb ie: 456mhz which would perform worse than what I currently have. Im in Australia so am not sure if these "magical" Celeron 366's are avaialble over here, if they ever made it here at all, so a little advice would be great, thanks.

dude i'm from melbourne and we have the good stuff!!.............keep your bh6 and get a converter for the socket 370,i have one of these chips running beautifully at 550mhz with the factory heatsink and fan at 2.0v....if your familiar with the computer swapmeets you can pick up a chip and converter for $130(aus)theres virtually no slot 1 chips but keep well clear from them........my chip was made in malaysia and the pack date was 04/18/99 run the defult speed(366mhz)through some applications and time demos to burn the chip in,then overclock don't muck around with 83mhz bus speeds because the agp might not like it......run some hardcore tests on the 550mhz speed and touch your heatsink,if you can keep your finger on it without discomfort then life is but a breeze,if too hot additional cooling is required but don't forget to keep your case cool as well.....................good luck!

I bought two '922' chips at a show and both run at 550 at 2.05V.

Thanks for the info guys. Cav, I have a fairly good cooling set up for case at the moment (originally had extreeme heat problems with the mobo temp reaching 50 degrees celsius at one stage) Still the chip is rock solid at 450. It's just a matter of trying to track one of these things down in Perth. PC, "922" chips can you give any more info on them at all such as dates etc, thanks. Also what would be a good converter card to use, so far I have heard some good things from the Asus one? And Finally do you think it is worth the risk in getting on of these chips since it would be useless at anything less that 550 to me, since I have the 300 @ 450 with 100 mhz fsb. If anyone else has had any experience with these chips at 550 let me know thanks.

I dunno Poly, it seems to be a crapshoot from what I've seen. I bought one of the 'certified ones' which runs 567mhz solid at the 2.0 default voltage after a period of burning in at 2.1. It looks like luck is more an issue of getting an overclockable one than any consistency in date/week of manufacture. I have a week 21, but most on the boards seem to be touting week 24+ or thereabouts. I was reading a thread the other night on another board which was reporting relative success rates and alot of the info was from small resellers who were testing chips from the same week of manufacture with successive serial numbers. Strangely (or not?) there was absolutely no consistency within batches; 5 of 20 would overclock to 550, 10 of 20, or none! So I guess ya takes your chances or make good friends with your reseller. I will try to find that thread (forgot which board it was) and post it here. Cheers,

Terry

Well now I can't find it but I do know it was OEM's vs retail versions that were doing it more often. While I was browsing around saw that many were reporting 80-90% success, so now I don't know what to believe! Except that them that are not successful are probably less likely to post results than them that are. If you have a good 450 tho, I don't know if it's worth a less than 25% jump in speed ? Cheers,

Terry

922=1999, week 22.

I have had experience with a total of 5 of these chips personally. The first two were '849' and would not go to 550 until I upped the voltage to 2.2. The next two were '922' that I bought at the same time at a show. Both are running at 550 at 2.05V. I'm currently formatting a drive on a machine with a 928 chip at 550 at 2.05.

I've only been able to get MSI slotkets here in Silicon Valley for some reason. I want to get some Asus slotkets to try out but have to find them first. The MSI's work fine.

Forgot to mention that my nephew has had one that would not do 550 at less than 2.1V. He sold it and got another that would. Thank goodness for auction sites.

Hmm, Well I dont really mind what voltage they would require running as long as it isnt anymore than 2.2 volt which is what my current 300a is running on. That said do you think that most Celeron 366's would hit the 550 given 2.2 volts. Or is it other things stopping, such as L2 cache quality? I have not had any problem with my 300a at 450 using 2.2 volts since I clocked it at this about 6 months ago, and it runs solid without missing a beat. If a chip wont overclock with 2.2 volt usually then I'll throw it in. Just a shame there isnt any places in perth, Western Australia, that sell pretested overclocked 550's

Well, my '849' would POST at 2.2 but that's all I 'd allow it to do. I think that it's a crapshoot with loaded dice as far as finding the good ones. Occasionally, you will get one that won't do it, but the odds are that you will get a good one.

overclockers.com has a huge database on batch numbers and success rates but like terry mentioned its more to do with luck but your chances are still over 80%

------------------

Hmm, well after looking around for one, I has become apparent that there are none available anymore where I live. Slowest Celeron CPU's is the 400mhz. That said I was able to pick up a cheap 366 2nd hand, and although it doesnt hit the 550 mark, it will make a great upgrade (Along with another BH6 mobo, and *mb graphics card) to my pathetic 686 200MX. At least now I will be able to play some half descent games over my LAN. Thanks for all the input on this guys, but it looks like i left my run too late. I reckon it is better to upgrade the 686 than my already fairly speedy 300a & 450, Cheers.

Poly, here is a place for the celery: ------- Oops, in the US. They do ship. Perth, is that in Louisana?
Intel Celeron PGA370 366 OEM---- $68 --------
Intel Celeron 366/128K OEM------ $86 --------
---------------------------------------------
Don't wait for ever, they ship most anywhere. I bought some of my 300A celerys there. Descent folks, they gave me batch #s at time of purchase. I havs known them for 10 yrs or more. I want to lay one or two away in case my 300As go limp with age or abuse. I just don't know which one is better.

Anybody got an opinion on which of these two celerys is a better bet?

Hmm, I am guessing there could well be a Perth in Louisana but the Perth I live is located in Western Australia, yep, down under. G'day mate, throw another shrimp on the barbie, and all that crap hence the problem trying to track one of those chips down. But not to worry, I have a pretty good set up now, thanks everyone who posted replies etc.
