2.4 c1, 2.53 b0 or 2.8 c1, please help

[pure]

Hi,
I am new to Intel, always been AMD, I have spent all ay reading this forum and learnt a lot from you guys, thx :)

Here is my question:-
Would you purchase a p2.4 - c1? or a p2.53 b0? or pay an extra £100 and go for a p2.8 c1?

I can get the proc for a good price off my friend, but he can only get hold of the 2.53 procs with the b0 core unfortunately :(

Advise would be much appreciated as I don't want to jump inot the decission and would like to be able to O/c upto and hopefully over 3ghz

Many Thanks :)

unfortunately, there is no way to tell which will be the best. generally, a c1 stepping with beat a b0, but by how much i am not sure. overclocking depends on so many things though... if your agp or pci slots can take it, hard drives, etc. it is all luck. i personally don't go for a chip to hope that it overclocks really high. i just buy fast stuff and if it happens to o/c well, then so be it.

P4 1C 2.4B expect around 2.8 Ghz with stock cooling or possible 3Ghz with a really good cooler. 2.53 I heard from alot of people they do 3Ghz easy. The 2.8 I wouldn't spend the extra £100

[batboy]

The 2.53 B0 stepping is a good CPU, but I might take a chance and get the 2.26 C1, since it might have a little more potential. Even if the 2.26 C1 only overclocks the same CPU clock speed as the 2.53 B0 (let's just say 2.9 gig in this example), the FSB on the 2.26 will be higher and the memory bandwidth will be greater. The 2.26 will probably post as good, if not better benchmarks than the 2.53 and you will also save some money too. Generally, I think the C1 has a good shot at exceeding 3 gig (heck, even some of the B0 2.26 were able to hit 3 gig). Just my 2 cents worth, but take it with a grain of salt as I'm speculating. Nothing is guaranteed in overclocking.

cheers for the quick replies. I also heard that the 2.8 isn't a good overclocker.

BTW - I will be using Asus P4T533-R and 256Mb - 1066 samsung rambus.
Aluminium Case, standard retail fan.

What chip u think would give me decent speeds?

[pure]

Also another point to thing about is the FSB on the 2.4 is 400Hz, the 2.53 is 533Hz. The mobo is designed for 533hz (I think)

[SporkSaint]

My 2.53 is pure gold...glad I didn't wait on the stepping
great price too

first let me say...WELCOME TO THE FORUMS.

well, since you are going rambus I think that any CPU that will hit 150fsb with the highest multiplyer would be best.

this is the point at your memory should hit at full 4x speed.
maybe a little higher.

because of the slim possability that the 2.4a might not hit this....I would stay away from it. if it was a 2.4b(133fsb) then it would be a good choice.

the 2.53 should be your best bet. at 150fsb, you'll be at 2850mhz and low voltage.....maybe only 1.6v or less.

yes you could always go higher with your OC but you then would have to back down to 3x memory speed.

the 2.8 might be pricey but if you could hit 150fsb it would be the best bet for you. a 21 multiplyer and 150fsb would give you great bandwith and cpu speed.
yet, what if you cant reach that high FSB with the 2.8 cpu???

what ever you deside I would forget about a choice of C1 or not to go C1.
it's now up to the OCing gods and a well plained purchace.

Well, my last post was about worthless, I somehow thought the choice was between the 2.26 C1 and a 2.53 B0. If you're talking about the 2.4/100 FSB, then I'd go with the 2.53 due to the lower multiplier. Sorry about the confusion, that's why my rank is "senior moment".

[pure]

Ahh interesting, I just learned that the 2.4 chip is a 2.4B (sspec : SL6DV) It is about £40 cheaper than the 2.53 chips which is a (sspec : sl6ev, which I believe to be a b0)

Should i still go for the 2.53 or take the cheaper option of the 2.4B?

The 2.8 I ain't bothering with.

I am sooo confused. :)

I'll keep this simple.......

get the 2.53 if you can. you'll get a faster CPU at 150fsb or so.
plus you'll have great memory bandwith.

only if you're running out of money should you get the 2.4b

ok, i am going to order the 2.53 with the b0 core. I will let you know how it o/c's :)

Too bad I saw this thread only now. I would *not* choose a known B0 2.53 core. With a P4T533 board I'd go for a 2.66 C1- 3Ghz within reach and good bandwidth at 4x...

[batboy]

I'd go with the lower multiplier C1 2.4B, why spend more for a B0 stepping?

I think the reason mica suggested the 2.53 is that this chip is more likely to peak out at about the same frequency as his RDRAM at 4x is. In other words- it's better to have a 2.53 @ 155Mhz FSB than a 2.4@155 because the multiplier and thus the gain is higher. Of course, I myself think a 2.66 C1 would be the optimal choice. :>

[pure]

Ok, from what I have seen of the 2.53 and the 2.4.

The 2.53 with the B stepping seems to get not much more than 2.8

The 2.53 with the C1 stepping gets above and beyonf 3ghz

And the cheaper 2.4B with the c1 stepping also seems to be getting at least 2.8 - 3Ghz+

If I have 256 Mb Samsung 1066Hz memory. Which is going to give me the best overclock in your opionion in regards to gamming? And will the memory bandwidth on the clocked 2.4 be restricted at all?

my point is this....

after you go past 150fsb or so, you will then have to run your memory at " 3x ".

say you can run your cpu at 160fsb....
160fsb x3 x2=960
or about 960 mem speeds...this is less bandwith then what your pc1066 can give you if you run at 150x4x2 or 1200 memory speed. maybe you can do a little better with your new sammy's, yet it will top off at around 1200 speed.

the more bandwith you can give the P4 cpu the better.

so I would go with 150fsb and 4x, then 160fsb and 3x.

now as for the 2.4b....there is nothing wrong with 2700mhz and great bandwith. that is what you'll get at 150fsb.

but why not 2850mhz...that is what you'll get with the 2.53 and 150fsb.

I also like what fizz said about the 2.66....yet this wasn't mentioned in your post. and the 2.66 is hit or miss at this time, with few peeps trying it.

I'll say this again....go with the fastest multiplyer you can, as long as it is a good OCer.

the 2.53 is a great choice, the 2.66 might be, and the 2.4b is only for the broke rambus users.

if you must go for the 2.4b, then 2.7ghz is nothing to complain about.

ok, thanks v much for your help. But the 2.53 chip I can get is onyla b0 stepping? Still worth it?

where as the 2.4 is the c1 stepping

again.....your magic number is 150fsb give or take.

all the chips mentioned should hit this, no matter if it is a B0, or C1.

also, I have seen C1 chips flop badly....so forget about should you get a C1 or not. and go for what will be best at 150fsb.

( it's all about the bandwith ):D

[pure]

ok :)

Here is what i am going to do, I have ordered the 2.4B @ 533Hz C1 stepping. Should be with me on friday. I will attempt to overclock it. If I am not happy, I will sell it on....then get me a 2.53 or a 2.66 :)

I think you'll be happy.

again, 2700mhz and 1200 mem speed = a great OC.

good luck

Personally, I think hoping to get 1200 out of PC1066 is a bit of a gamble, you might not make it. How many people are getting 1200 out of PC1066? Is this common? I don't know, but it seems like a stretch. So, if you can't achieve 150 FSB with the 2.53 using the 4X memory divider, you've lost out on the hopes of max bandwidth, especially if he really wants closer to 3 gig overclock. In that case, the lower multiplier might be better, assuming he can hit the high FSB with that chipset. To be honest, either CPU would of been good, we are probably splitting hairs here, but I think the 2.4B C1 has the best potential of the ones he was considering. Let's hope he gets a good one (crossing fingers for luck).

[markodude]

Sorry pure but after my experience with the P4T-533R (are you getting from scan?) I would advise against getting it unless you know its a rev2 with the voltage regualtion problems fixed.
I certainly couldn't get it to run stable (even at default) with my 2.50 C1 stepping, was ok with my 1.8A on a 130FSB, which is the best I got out of it.
Also RAMBUS is pretty much dead, so you will be limiting your upgrade path, right now I would go for a P4PE or something if I had to. Realistically its a bad time to buy as Springdale DCDDR mobos and 800FSB HT chips will be with us early next year, Ill not be buying any Intel chips or Mobos until then, going to spend my money on cooling and an Nforce2 board for my 2400+...:D

[pure]

not sure if it is a rev2 :(

it is comming directly from manufacturer so hopefully it will be a later board. Im not paying much for it, so if it isnt upto it, ill sell it on in a week or so. shouldn't really loose anything on it....I hope only paying £170 for it, and that is with the ram.

[markodude]

Good luck, it is a nice board on paper I just hope you dont have the problems that I have had.
I ended up swapping for the P4B-533E and 512MB XMS3000. When I run at 158FSB and DDR420 it is faster than the P4T-533 was......although that was with a 2.50 rather than 2.53 :D

[NinjaZX6R]

Wow, I just spent half an hour reading all the replies. Now I have the stupidest question of them all....I am an AMD guy, but I just switched to Intel as well. I got the P4 2.4Ghz 533 FSB. Now which stepping do I have, or how can I tell? I know there is a 400mhz and a 500mhz FSB model. Please help me, I wanna be in on this stepping! Haha, thanks.

[jgtdragon]

NinjaZX6R,
You still have the retail box for your cpu? Type the last 5 characters on your product code. You can also tell by the default voltage being 1.525 instead of 1.5v

[NinjaZX6R]

SL6EU......so which core is better? Oh, and which one do I have?
-Collin-

THANKS FOR THE HELP!

[batboy]

You have a B0 stepping. The C1 stepping is the newest core and has the best overclocking potential.

Damn, better luck next time. Thanks for the help though!
