quick celeron 266 question

[cyberey66]

Is the celeron 266 multiplier locked?

[batboy]

Yes.

[cyberey66]

Some of the people in the CPU database claim to have unlocked versions. Where any unlocked, or are they either lying or have an enginnering model?

[Bender]

They could have engineering samples that are unlocked. To this day intel doesn't lock the engineering samples. I wonder how tought it would be to get one of these chips.

[cyberey66]

I'm going to enter that overclocking contest, on the main page, and I still need to pick a chip of choose. I guess either the 266,300 or 300a. Possibly the 533 FCPGA. The old celerons look better though because they are always floating around ebay for about $5-15 and can be lapped to the copper. I need to get a about 100% OC to contend, very impossible, but it will be fun trying.

[batboy]

All commercially available Celerons had locked multipliers. There were some early P-II CPUs that were not locked. If you're going for at least a 100% overclock, then my choice would be the Celly 266 or the Celly 533a. I've heard of several people hitting 133+ FSB with those old C-266, they were amazing overclockers. Use a BX mobo with a 1/4 PCI divider and mega cooling mods, sweet!

[Yodums]

Well, they are locked.

As for 100% overclock I would either recommend the Celeron 300 or 533.

If your board can support the Celeron II then get the 566 boy those overclock 100% easily.

I'm not really a fan of the small exposed core though. I like the huge cores from the older ones that can be lapped to the copper. IDK, I always wanted either a 600 or 566, I hear people getting them in the GHz with Gorbs!! Well, the contest goes by ratio, so the overall clock doesnt matter. 266 has to do 532 for 100% and 566 has to do 1132.

[Yodums]

533 maybe hard to get to 100% as the max was 100% and I don't think you'll be able to hit the max where the 566 max was 1275!

If I had a better PSU before my mobo blew I probably would have hit 1Gig.

I had a Celeron 300a and max I could overclock it was 504 MHz. I had a Celeron 566 (cB0 stepping), then sold it, then recently bought it back, but I never could get it stable above 1 gig. It was very stable at 978 though. Sorry Yodums, it's not always "easy". Personally, I still think the Celly 266 or Celly 533a would have a better shot at going for 100% overclock, but nothing is ever guaranteed.

Contest...i looked around and didn't see anything about a contest

[MadMan007]

Satan, send me a PM. I have a celeron 266 sitting in the closet that I used for a couple years @448MHz (112 bus) at 1.95V which is .05 below default. :cool:

This was on a BH6 rev. 1.01 (no 1/4 divider) with crap RAM, stock cooling, and RadioShack crap thermal paste. I could not get a higher FSB, prob due to RAM. The CPU showed up at 496MHz but I got memory errors during POST. I dont remember the CPU temps, but even in the summer with no A/C it never locked up.

Anyway, I'd be willing to sell it to you. PM me...

Anything but that 266. Worse CPU Intel ever made in the Celeron line. I thought the only people that still had em lived in caves. You must be the exception.

Tell me, how much L1 & L2 cache does that 266 have?

yea it's gonna suck, i should search for the 300a, but for ocing I might get great ratio results from the 266.

[MadMan007]

First to answer your question:
It has 0 L2 cache, same L1 as the PII. 32k I think?

As for this part of your post, why the hostility and insult? Do you know me? No. So much for being civilized...

I checked your profile expecting you to be about 14. To my surprise you are 24. Obviously, you got into DIY computers later than I did.

At the time I bought it, the celeron 300a was not out yet and I needed a new computer for college. AMD was not a reasonable option-the platforms for the K6 sucked. The PII 450 was the top of the line, and it cost a crapload of $$, and even the PII 300 was pretty expensive. It was well-known that the celeron 300 (non-a) was a poor overclocker, as boards at the time had FSB options of 83MHz, 100MHz, 124MHz, and a few had higher ones. No one-step FSB options.

Anyway, for the low cost, the 266 provided great performance when OC'd to a 100MHz or in my case, higher, bus. It served me well for quite a while and along with my STB Velocity 4400 w/TNT chipset which was brand new, could run anything. I also had 128MB of RAM which was a lot at the time, most people had 64.

I responded to this thread because satan asked about 266's twice, and even said it might be a good option, which in terms of OC %% it is. As far as being a useful CPU anymore, it is not, and that is why it is sitting in my closet. So, please don't insult me or anyone else who was has been DIY since the beginning of the OC craze. It was the best option for price/performance at the time, and could serve satan well in terms of OC %%, especially since it ran that fast at lower than default Vcore...

[batboy]

I still can't find the CPU overclocking contest you're talking about even with that link.

Yes, the Celly 266 is a great overclocker and was an early pioneer for extreme overclockers and a classic. True, it didn't benchmark the greatest because lack of cache, but my understanding was that he was going for percentage overclocked, not performance.

Ok, everyone take a deep breath and let's not take things too personal. Everyone has a right to their own opinion, even if it's not entirely correct. Please, let's not have any personal attacks or flames. Thank you.

MadMan007 , you got PM. I think I'll probally buy that CPU from you. One question, did you lap it yet? If not that makes it sweeter, and I'll have a few temps lower when I hit the copper. Almost booted windows with a celeron 433@650 with the copper lapping. Given the core is basically limited to 550, just posting 650 is a task. Well, I still got a lot of time before I start for the contest, it ends in like june I think.

[Ebola]

I had batboy's celeron 566 up to 995 and it would post at 1054. if i had the glaciator II back then I might have been able to get into windows at a gig. this was a 566 cbo too so it really was an amazing chip. the cco 566's were amazing.

[Yodums]

Yea Ebola, I had one of those chips which was a 566 cB0 @ 850 I knew I could have gone higher with a better board and better cooling. As for Celeron's being the worst Intel creation I doubt it.

Infact the only disapointment IMHO that Intel has created is the P4 Williamette they weren't going up to par with their high speeds as P4 1.8 were being outbenchmarked by 1.4 Tbirds!

The Celeron is a great chip for overclockers, the only downside to them is the low cache. They overclock very well to FSB's 140+ on regular basis and they really match up to their big brothers the P3.

My two cents.

[batboy]

Hey Ebola, Once I get my P-4 system up and running, I might try one more stab at overclocking "our" cB0 stepping Celeron 566. I have a better mobo now (Abit SA6-R with cooling mods) and a better CPU cooler (lapped GlobalWin FOP with 80mm high output fan). I also have better case cooling and better RAM too (Kingmax PC-150). I almost got that Celly 566 to finish loading Windows once at 1015 MHz, but I moved the mouse and crashed it. Maybe I'll open up some windows since it's winter...hehehe.

[deez]

I think all those contests are old

[MadMan007]

You got PM "satan."

Heh, I just realized I'm making a deal with the devil :D
Maybe I should ask for his soul?

I thought the devil was supposed to get your soul :mad:

[takiwa]

don't know if it'll help, but i got 1 p!!266, 2 p!!350's, 2 p!!!450's, and a celly333, if ya might want 'em...not for free, of course ;)
