Any succesful 633->950 OCs out there? What are the chances?

[Innoka]

The Celeron 633 is the lowest celeron to currently be found where I am. You can get the 600 from some places but not necessarily cheaper than the 633. I am going for a FSB 100 overclock. I am aware of Overclockers.com but I find it isn't that current. If succesful it would work out a lot cheaper than a P!!!800. I already have a power cooling fan.

A guy had the same question earlier today. Check out my responses to his post HERE.

I have heard that some of the 600s do not O/C as well as the 533 and 566s did. You may be better off with paying a little more and getting a pretested C2 633@950.

Hope this helps. . .

Innoka,
You can check overclockers.com's database. I currently have a Celery II 633 running at 933mhz, but I'm running it at 1.85v. Personally I think that is alittle high, but I bought the chip for $80 so I'm not really concerned if I burn it out. I think the 633mhz is about as high as you want to go. For the safest bet I'd get a 566 and run it at 850mhz. That is suppose to be a very easy mark to hit with that chip. Good luck.

for the 4 comps i made with celery IIs, i've had great success o/c ing..
600 --> 900
600 --> 900
633 --> 950
633 --> 950

they were earlier cpus.. and i upped the voltage about 15% average..

sorry cant remember the details.

I have a Cel633 with a CUSL2-C and it will go to 950 @ 1.80v. But I get occasional freeze-ups. I could increase the voltage but I want to get a better hsf. I only have a Chrome Orb and I would like to get a FOP-32 instead. Then it should be cooler and more stable.

 

[Blayze]

I have a Celeron 633 (retail cB0) that does 950 at 1.75v
will not do anything above 950 even at 1.85v

using a Abit VH6 motherboard

 

[BlueWeasel]

Mine does the same thing, Blayze. I have a 633@950 at 1.75v but the chip will just not go any higher. I can bump my FSB up 102-103 and even with a voltage bump of 0.15v to 1.90 the chip will not run stable.

This is on an Abit BE6-II MB.

 

[Innoka]

I would prefer a more certain round 100fsb or more overclock, reason being that I have found "underclocked" fsb settings unstable. I'm disappointed that I may not have a chance to reach the magic gigahertz with it...

 

[novice]

I would think that the Cco stepping Celeron 633 should have an excellent chance of hitting 950. My Celeron 600 does 900 at 1.65 volts and is very stable. I am using the Globalwin FHP 308 cooler. I will be helping a friend put a similar system together with a cCo Celeron 633 in a week or so. I will let you know how it goes. BTW, on Wintune benchmarks, my Celeron 600 @ 900 beats my PIII 500E @ 744 on the same motherboard.

I too have the same problem with my Celeron 633 not going any higher than 100FSB. I think the Celeron 633's are reaching the max of intel's technology, just like how you can't really OC 1gHz chips that much.

 

[Innoka]

I have bought a celeron. Is there anybody else who would like to contribute?

 

[Wik]

I have had 4 C2 633@950 retail
My friends C2 633@998 OEM can do 1054 but the Gorb will not cool it enough.

 

[hans007]

friend of mine's did 950 at 1.75 volts with a gorb. thats kinda lucky, its a cc0 though, so you should get a cc0 if you can

 

[Innoka]

I have a Celeron in a security sealed package here. How would I know it's cc0 stepping- shouldn't I just assume it is? It's a delivery batch to my (big) supplier they've been waiting for.

 

[Drifter]

Celeron 667 @ 1000

 

[Rebels7]

I have a 633 that runs at 1007, at 1.9V. Can run at 1026 but is not stable!!!!

 

[The Reaper]

My 633 runs at 980 with 1.85V (cB0). Temp is ~ 45C at full load 24/7 with PEP66.

 

[Wik]

What are the numbers on the box? When was it made?

 

[The Reaper]

If you mean me it's a week 32 2000 Malay cB0.

 

[Wik]

No I meant to put Innoka as the target of my question.

 

[Innoka]

Don't know, I'm not there to open the package and I might try to exchange it anyway. I have found the 950 would go like a P!!!800/100. Look at this for a sad fpu benchmark: 3D Studio Max2. Clock for clock the AMD chips are 50% better.

 

[thermite88]

I am two for two overclocking Celeron2 633 to 950. Both need 1.80-1.85 volts vcore to run Prime95 stable indefinitely.

The Celeron2 is more motherboard sensitive than the P-3's. The Asus P3B-F and CUSL2 work well, but I have had stability problem with some other MB.

The Celeron2 950 does not run nearly as fast as the P3-700 oc to 933.

 

[Innoka]

You might be right there.
Recently delivered Celerons are looking very good for overclocking; people are selling guaranteed overclocking 633s for only 5 extra. This means they must be just about all doing 950.

Reaper,

You are using an abit bx6 r2 for your celery 633. So am I, but my bios (QR) does not recognize the 633. I don't know if that is a factor, but when I try to bypass the request to return to the bios setup after setting 100 mhz as the fsb, the thing will not boot and refuses to reboot until I take out the processor and insert my old PII. Do you have a different bios and what is the rt1 temperature? Finally, what is your slotket? Mine is MSI 6509.

I have a CII 566 at 112 bus. Would it be any faster than a 633 overclocked to 950 on a 100mhz fsb?
