buying a pIII 700

[Guest]

is it worth to buy a pentium3 700 (100 mhz fsb)now an try to overclock above 900 mhz or save the money and buy a p3 800.how does a p3 700 perform?is it good for gaming or maybe i need a better cpu?
i´ve got a soltek via apollo pro 133 mainboard

In general, PIII 700 CPUs will overclock to 933mhz or better.

PIII700 (socket 370) running 24x7 on an Asus CUV4X at 148FSB = 1036Mhz.

Fantastic chip ;o)

The PIII 700 at 933 will outperform a PIII 800EB by a very large margin. You should not overclock the 700E to less tha 933, because at 933 your PCI bus and AGP bus go back to stock speeds. So overclock the 700E to AT LEAST 933!

Why not go with the faster FSB 733's or 800's at 133FSB to start with?

From what i read in this community startin with the faster FSB gives ya quite a bit better real thruput(bandwidth) per total clock speed to begin with!

And I can actually feel the differance between an 800 100FSB and the 133FSB. Runnin Visual studio compilers and debuggers the 133FSB's signifigantly runs away from the 100's. And hittin a SQL Server database there's literally no comparison!

So why does anybody opt for the 100FSB if their mobo supports 133+ FSB?

Is there something I'm not gettin here?

for one the multipluer aren't as high so you have to up the fsb more together the same increase in totaly speed

also if you incresae to the 133 form a 100 you come back into specs for the other busses on the system

I get it IF? Almost Every PIII700(100fsb) will do 133fsb.
That’s 933 bang for 700 buck...

My experience with bumpin 100fsb's goes easily to 112 & 116, 124(50/50?), and maybe(?)128. After that it starts gettin tuff! Need serious cooling, voltage mods and good components. Admittedly my experience is limited and doesn't include a wide range of chips(some 450's, 600's, 667's and one 800).

But some chips are just better for OCin than others. Like the plain ole porcelain P200, every one I ever tried or heard of would go 83fsb for 266, and rock solid. But the P200 MMX was a 50/50 chance of 75fsb and 233. Is the pIII700 one of those overly OC-able endowed chips?

Think 933 outa a 700 is a sure thing? Stable? Without a voltage bump?

And eariler posts on OEM Vs Retail boxed CPU is interesting? I've used OEM's from mail order and boxed from computer shows with equal success and OCin(I bump everything to Max and back off to Stability) . Think its true they're different core materials and/or specs?

He was asking if it would be worth it to buy a 700E and overclock it, or if he should buy the 800EB. Well, the 700E will ALWAYS perform better when OVERCLOCKED to 933 than the 800EB will stock, because at 933 it operates at 133FSB. It is also cheaper. Further, overclocking the 800E to 930 would require a 155MHz FSB, which is likeley to cause other parts in the system to fail. The 700E will go to 980 at 140, which is still a little faster (even with the 140MHz FSB), and less likely to result in the failure of other compnents to work at that speed.

To get the 733 to 935 would require a 170MHz FSB, DEFINATELY out of the question.

Like the last guy said, it's a matter of multipliers, the 700E has a 7x multiplier, the 800EB has a 6x multiplier, so the 700 will run at a very respectable 933 when overclocked to a standard 133 bus speed, wheras the rest of the components (PCI, AGP, and PC133 memory) will not be overclocked. Meanwhile, the 800EB will run at-800 when set to 133.

Most PIII processors have a difficult time getting over 980MHz, which means that the 750@1GHz is not usually a viable option. So overclocking the 800E (the 100MHz version) is a definate no-no. Which leaves teh 700E as the best choice for overclocking.

700's are priced right: Price watch has em ~$100...
Might try one myself. I'm not always lucky at getin signifigant OCs like 100 to 133 fsb on all chips... Its a crap shot. Can always get 10-15% fsb bump, seams luck of the chip after that.

If I keep hearin most 700's will really go 933, then I'm going to get one!!!

Ever run into PIII700 that won't go to 933(133fsb)?

I hear that only 97-98% of them are overclockable to 933 and above. It is harder to overclock them to 124 than 133 because at 124 you PCI is oveclocked by 24%, but when you reach 133 the PCI goes back to stock. Nearly all 700 and below chips will overclock to at least 133FSB. For the 700 that gives you 933, for the 650 it provides 866, for the 600E it provides 800, so with all of these being priced within a few dollars of each other the 700E is the best deal. Although 2-3% of them will not overclock to 133 from what I hear, I have never actually SEEN one that would not. Normally 1.75v is required for total stability, with some requiring less, and I have never seen one that required more. The BIG Intel retail fan that comes with the 866 and above is good enough for cooling, but I use a Thermaltake VolcanoII on my own system. I wrote a review of the Thermaltake VolcanoII which you can read <A HREF="http://forumz.tomshardware.com/hardware/modules.php?name=Forums&file=viewtopic&p=631261#631261" target="_new">HERE</A> if your interested.

As the man said, I 'upgraded' my PIII733EB to a 700E. Managed to pass on the 733 with some old memory for ~$100.

The 700E, with a .05V increase, runs 1036 (148FSB), 24x7 100% load at 44 degrees C with a fop38 installed.

Rock solid....

I do have a Asys P3V4x just wastin potential with a PII 450 in it. Have it runnin smooth at 558(4.5*124) but its still a waste of a good Mobo.

Looks like all 700's aren't created equal either. Some are PIII700 and some 700E. Guess the "E' means enhanced.

I think I can that Mobo sayin "Give me that 700E!"

 

[peteb]

Well, I bought mine 2 weeks back and it's fine!!!! I guess the newer ones may have a good yield?

All 700's are E's. There are only two version of the PII Copermine available the E and the EB.

The E comes in 500, 550, 600, 650, 700, 750, 800, 850, 900, and 1000 varieties, while the EB comes in 600, 667, 733, 800, 866, 933, and 1000 speeds. So the only speeds available in both flavors are the 600, 800, and 1000.

Some venders are just too lazy to call them by their right names, every one of them has an E in it (Either E or EB).

Their are also PIII Katmai core processors avaiable in 450, 500, 550, 600, and 600B varieties, these older processors are the ones without the "E", but notice that no 700 Katmais were available, so all 700's are "E"'s.
