Alright, they can't get me a 800E, so now if I want a P3 in my budget I gotta go for an 800EB. Is it worth it? Its going into my DFI CA64-EN until I can get a new board that can OC.

My specs.

Celeron 600@900
DFI CA64-EN
512mb PC-133 ram
15gig Seagate Barracuda II
ATI Radeon 32 DDR
SB-Live X-Gamer
8X Panasonic DVD
36x Acer CD-Rom
NIC for DSL

I love my 800EB's. Make sure you get cC0 stepping. They OC better. I've gotten mine to 990, and with some more tweaking I'll hit 1002.

yep I love my 800EB as well , its soooooo fast , might have something to do with the 167fsb that im running! lol
get it man , that chip rocks!!!!!
o/wise get a 700E/933EB or a 750E/1ghzEB as they are very flexible.

good luck with your choice.

WOH! don't touch an EB chip of any speed for overclocking unless you have lots of money and only want a 10-15% overclock.
The EB's are a bad choice for overclocking because their bus speed is 133mhz which means you are relying on very high bus speeds for an overclock.
I always recomend the p3 700 for overclocking as this will go to a 133mhz bus speed quite easily and maybe higher, where as an 800 eb is likely to be throttled by ram, vid card or pci components before the cpu max's out.
Definately go for the p3 700 it is the best choice for intel overclocking by far.

Dude I say if you can get it for dirt cheap buy the thing. If you can't, built your own DURON, they are bad azz for O/C...and cheap as all hell

from the prices I've seen they are usually about $180-200 where as the 700 is only about $100 or so and the 700 will probabally overclock higher.

Like I said in one of the other threads you started the EB chips can be quite good but only if you have the components to run at very high fsb's. It doesn't look like you have whats needed to push the EB so I would stay away from it and go with an E.

Phil

E chips are still usually much better, look at Mr.B's 600E which he got to over 950mhz, This is probabally close to what an average 800EB gets and this is a cBO. You can't beat the 700 for overclocking as it is more likely that the chip has reached it's limits than your components.

10-15% overclocks in 800EB's?!?!?!

Umm...look at my info, and up above there is a guy that us running his at 1002.....that blows your little 10-15% theory all to hell don't it?

Yes, you have to run a high FSB. Whats your point. Oh youre worried about your cards not working...... I have only posted here a few times and most of them have been to remind people that Your FSB has nothing to do with your cards not working! It's your PCI bus speed. If your'e worried about that, go guy a good motherboard that will let your customize your PCI bus....like a VP-6!

I agree, 700 P3 is a good overclocker, and better than the 750 or 800 in proportional increase, meaning it has a higher percentage gain... as a rule of thumb, the 133MHZ bus is high to start, pushing it past 150 will almost peak any standard memory... and investing in more memory to offset this, then more cooling to push higher, will defeat the purpose of overclocking to begin with -- saving money by not buying the top-shelf processor and pushing a slower one to meet it for less $$$.

P3 700 gets my vote, but you can always take your chances, since that's what most people do, and cite the exceptions... check the CPU database, it speaks for itself.

The way I've always heard tell, is to go with the "E" series P///'s. You've got more overhead to work with when overclocking, as you start with the 100 FSB speed, opposed to 133.

That 800EB is by and large, similar but different than my 600E. They both have the 6x multiplier. If I run anything at or over 133 FSB, my rig "sees, and calls" my 600E a 800EB.

I've gotten mine to 954 MHz (159 FSB) This puts it in the top end of the database on the frontpage here. I have seen a lot of posts concerning the 800EB, and quite a few of them are goin' faster than my 600E.

The "EB" chips seem to be better at overclocking than they once might have been. There's also a growing number of people claiming speeds once thought unreachable or impossible with a Celeron 800E.

Time, practice, and refinement seem to have made the Coppermines better over recent past. If they continued to get better, intel should stick with them, and dump the P4's they've been making. Can't wait for Willy 2... those should be darned interesting to see how well they o/c. =)

But those are a ways off yet...this is the now. Overclocking is an art, and every chip/canvas is different. That 800EB might get 950, perhaps more. I'd have to say, the chances seem better now than they ever have of an EB overclocking well.

I'm toying w/ the idea of getting one of those C800E's just to see if it WILL in fact run in excess of 133 FSB. I still think I'd rather a 700E P///, though. Proven track record.

I can't "bad-mouth" the "EB's" anymore...I'm getting blown into the weeds by too many of them.

I know that it is the pci bus speed that causes problems, but seeing as the pci bus speed is derrived from the fsb and as far as I know the maximum divider available is 1/4 so the high bus speeds do affect your peripherals. All I'm saying is that some on is going to be more pleased with the over clock of a 700 than an 800eb as with the 700 they are likely to reach the limits of their cpu not memory/vidcard/pci components. As for the 10-15% I did the calculations wrong in my head I meant 20-25%.

I agree that for most people the E series of chips is better but for those of us that have the components to run at >160fsb a whole nother set of options are open. Going to 160 -166 fsb will most times max out an EB chip anyway so the end result is the same except you end up at a higher fsb and greater memory bandwith.

I pushed a 866eb to 160fsb at 1.9v and to 166fsb at 2.1v which results in a very impressive machine. It just may not sound as pleasing to the ear as taking a 700e up to simmilar speeds.

I got the 866eb dirt cheap used, if buying new I would have got the 700e and super cooled it if need be to get it up to a high fsb :)

Basically all I am saying is don't dissmis the EB as not being good, under the "right conditions" they are about as good as it gets.

does any one know if there was ever a 600 and 650 p3 cCO chips

well depending on prices, when I build my P3 system I am looking into either a 900+ EB cpu or the p3 700E. Not sure, I would like to overclock, but I will get an AMD system to play around with. I really want the P3 as a lan rig, so I can go excessive with. Oh well, I have time to think about it.

Phil

The p3 is old hat now and not a cheap old hat at that.
The only reason I can see for buying a p3 is if you have an old slot one system thats needs a cheap upgrade in which case the p3 700 (it isn't actually the 700 E as intel only labels E when there is another chip with that speed such as the 550 or 600)

The letter E denotes a processor with a coppermine core.

Phil

I was just being picky and I know it is to do with it being a coppermine, but intel only labels chips that have other versions at the same speed, for example the 600 has 4 versions, the 600, this is the katmia 100mhz fsb, the 600B, katmai 133mhz fsb, 600E coppermine 100mhz fsb and the 600EB which is the coppermine 133mhz fsb, the 700 is only available in 100mhz fsb coppermine though and so is only called the p3 700 not 700E, like I said I was just being picky.

yes, Phil is so correct! I know exactly what you mean..
the P3 700 is just called P3 700. Any P3 CPUs clock rated speed of 650 and Up are all Coppermines automatically, so an Intel don't mention the letter "E" and they use "EB" when needed. Katmai cores are available starting from P3 600mhz and below. This really explains itself clearly by refering to Intel's processor S-spec information. ( http://support.intel.com/support/processors/sspec/p3p.htm ) While some Coppermine chips are also available in 600mhz, 550mhz, 533mhz, and 500mhz. This is why Intel marked "E" to any of these clock rated speed chips to distinguish between Katmai and Coppermine so it won't get confused. :*

I know I added "E" next to my P3 700 even though it doesn't need it but because it looks nicer with it, haha but it's actually just called P3 700.

When people know what they are saying, them saying P3 800 for example, you should assume it as a P3 800 Coppermine at 100mhz bus automatically unless they mention it's 133mhz bus.

And P3 933 for example, it should be assumed that is Coppermine that runs at 133mhz bus. They dont say it 933EB cauze being Katmai core in this clock speed doesn't exist.

I hope I cleared some things up ^_^ and this is what Mr. Phil already knew.. that's why he mentioned about it in his posts here. :) Have you new people learned something new today?? I hope so!!!!

For example when I first got my celeron 600 my bx board didn't detect it correctly and called it a pentium 3 578E but when overclocked to 900mhz called it a pentium 3 892 minus the E. I got a new bios that gets the speed right and calls it a celeron now.

Yes, Intel did make a 600 & 650 cC0. I have heard very few people having these chips though. If you check the Intel website specs for P3 chips it says they have them in cC0.

Phil

at 600 or 650 cCO would be a killer overclocking chip I might have a look out for one.
