What to expect out of a Celeron 2.6?

[gvblake22]

Ok, my friend has a 2.6GHz Celeron 400mhz w/128 L2 Cache. He wants to OC it as much as possible w/ a XP-120 HS/f and I really know nothing about intel overclocking, especially on a Celeron.
So what do you guys think he can expect out of this chip?

Motherboard = Asus P4S800
RAM = Kreton PC-3200 (latency unknown)
Generic 400w PSU

Thakns!

Celerons have bene knows to O/C pretty good - only thing to do is make sure that mobo - which i am sure it does is turn on PCI/AGP locking and up the FSB in increments of 5mhz at a time - start it up - run prime 95 / BOING or something that will stress the CPU %100 - keep and eye on temps and keep going u ntil the system crashes or freezes, then clock it down :D

Anything over 3.4 possible?

I got a new Intel Celeron-D 2.4Mhz for $67 and it overclocks stable at 3.6Ghz - no errors with memtest86+ or Prime95. Errors start only at around 3.8Ghz. 3.6Ghz is perfect its 200Mhz*18 so 1:1 for DDR400 RAM. I'm using the stock heat sink/fan with Arctic Silver 5 and core=1.40V with an Asus P4P800SE motherboard.

no to hijack the thread, but thebadboy, thats what i am seeking to do, 3.6Ghz with a celeron d. I am gunna try with a 2.6Ghz celeron d. What company is your RAM from? or is it generic. I assume you're running 800 by 4.5x to get the 3600Mhz

Celeron Ds overclock amazingly - i think i need to scrape some cash and get a budget rig to play with ;)

Celerons based on the Willamette core dont overclock so well, unfortunately.

[larva]

Yes, but he has neither. A 2.6 Celeron is a Northwood core (at least C1 stepping) and like P4s of that era generally clock easily to 3GHz. More than 3.4GHz is similiarly unlikely.

The 2.4Ghz Celeron-D is the best since it has an 18x multiplier with standard 133.33Mhz clock, so with a 200Mhz clock setting you get 18x200Mhz=3.6Ghz and 1:1 200Mhz clock for DDR400 RAM. I'm using cheap Kingston Value Ram 2 sticks of 256MB PC3200 I got for around $40 each. My Asus P4P800SE (865 chipset) can enable PAT for a clock of 200Mhz or less but turns it off above 200Mhz, so the 3.6Ghz setting is just right. A faster Celeron-D might not overclock any more but you would be stuck at a lower clock for 1:1 RAM speed and you spend more, so I'd recommend the 2.4Ghz version. Be sure to remove the grey thermal pad from the stock heat sink completely before use, and clean any remaining residue off completely with isopropyl alcohol. Then use either white thermal grease or a tiny amount of Arctic Silver 5 for lowest temperatures.

Actually the gummy grey TIM Intel currently uses has proven superior to white thermal grease and very close to AS5 in terms of thermal conductivity.

I don't believe he has a Celeron "D". I think it has the northwood core (128k L2 cache and 400mhz bus speed). Will it yield different results?

800mhz is the bus speed, not FSB, even though they say it is. The P4 has a quad pumped FSB, so you divide 800 by 4. That gives you 200mhz.

Look at my signature. My processor is a 3.0C, which has a 200mhz FSB(by default) and a bus ratio(multiplier) of 15. 15x200=3000mhz, or 3ghz. You can see I run it at 240FSB, which would come out to 3600mhz. To get the bus speed we multiple 240 by 4, which is 960mhz bus speed. Understand that now?

Now to the original poster, I had a 2.6ghz Celeron a while back. It was a D1 stepping. It was on an Asus P4P800, which wasn't too great of an overclocker. I ran it at 115x26=3000mhz, it wouldn't post at 116fsb for some reason. Oddly enough when I got my 2.4C I couldn't run that past 250FSB, which happens to be 3ghz also. I think the board was limited to 3ghz. That celeron passed prime for hours on end at that speed on stock voltages and a stock heatsink.

So you'll be able to overclock it a bit, but 3.4ghz and beyond is a little too high I think, unless if you had a nice mobo and really nice cooling, and not to mention a really nice chip.

for the poster that has the 2.4 @ 3.6, is there anyway you can post some benches?

Are you talking about me?

I had a 2.4C at 3ghz and a 3.0C at 3.6ghz, but never a 2.4C at 3.6ghz.

My benches arn't all too exciting, nothing to really see. Just numbers... :p
