Just OC'ed my friends P4 2.8C...

k thanks!...sorry didn't mean to offend if i did.. i think ima go with the ic7-g and the 3.2 c...if i'm saving 50 bucks i might as well spend 100 more on the processor =)...mebbe 3.0 haven't decided yet...do either of those processors clock as well?
 
Okay, I'm just going to answer both in one post. A 2.4C or 2.8C with M0 stepping is a 3.2ghz P4-EE with the level 3 cache disabled, presumably because it had a flaw in it. But they overclock like crazy, since they got the same core as the 3.2EE. Most of the people who bought one of the 2.4's got them to run at 3.6ghz with just a slight voltage bump, and some people are getting 3.5 or even 3.6ghz with the 2.8's at stock voltage.😀 Oh, and the 3.0C and the 3.2C both overclock great, with 4.0ghz not being unheard of for the 3.0, and slightly higher with the 3.2's.

well i remember awhile back tomshardware OCed some P4EEs to 3.6 and 3.8ghz and put them on a benchmark against all the other processors at the time, and the results were less than thrilling,didn't yeild much of anything above 3.4ghz. a day later i checked back and tomshardware apologized,and claimed there were "errors" in their benchmarking and they had to remove them from the site. it was never spoken of again.

i AM NOT SURE WHAT THE HELL YOU ARE TALKING ABOUT....I figured you were going anti Intel on the slant....

I can tell you from my testing.... My 2.4 does 3.42ghz at stock and 3.5ghz with a slight boost to 1.6vcore....

Here are the results.....


Now remember genius that a 3.0 to 3.5ghz represents a 16.7%% increase in clock speed and the 2.4ghz to 3.5ghz is a 45.8% increase...I think you will see many times it scaled near the actual clock speed increase. In test it did not I can tell you those are not cpu intesive apps like winrar, NAV2003, etc. as the the cpu utilization charts showed.

The P4 scales quite well....I wish I would have ran the barton at 2500+ so I could see it there....However it was so disappointing at 3200+ I didn't see the point....

Anybody still question the power of HT????? a 2.4ghz HT can equal a non HT 3.5ghz...phenomenal!!!

okay last question ...i wanted to thank you once again...do the 2.8c with Mo stepping have specific different model numbers? How can I tell the difference between the two cores ? Okay so that was two questions... =X


never mind i googled it and got the model number SL6Z5

but now here is a question do u spend 200 on the SL6Z5 or the 3.0C?...my rational is that I knnow that any SL6Z5 is going to be a good overclocker while buying a 3.0c is kind of a shot in the dark...any thoughts?
 
I also have a 2.8c M0 and i was wondering since i still have stock cooling how much i might be able to o/c it?
