What's so special about Engineering Sample CPUs ??

post #1 of 8
Thread Starter 
Hello, I am new at this. I want to overclock my P4 2.8 Prescott. I have a software showing me that my CPU is Engineering Sample. I remember someone in this forum or another saying something about Engineering Sample CPUs...But I can't find it anywhere. So what's so special about these Engineering Sample CPUs ?? Pros and Cons about it would be appreciated.
What's the potential of this CPU can do ??

Thanks...

They have unlocked mulipliers which help. Instead of havign to run high FSB, you can run lower FSB and a higher multi which would allow for a higher overclock, but more raw fsb is faster though.

Its nice because its a lot easier to max out your cpu. Im running a 3.2 but i cant get past 4.2 cause my board wont let run more than 263 fsb. Now I have a 3.6 ES on the way and dont have to worry about my board limiting me

Wow..thanks for the info. I've looked in my Abit IC7-G SoftMenu BIOS. My "multiplier factor" min=14 and max=14. I can't change that multiplier number...14 is the min and max. I also tried playing around with "Ext. Clock (CPU/AGP/PCI) 220/66/33MHz. It would not boot into Windows all the time. First time I tried 220 it would boot into windows xp fine..used it for a day and then tried 225. It would boot into windows once and that's it...From a 2.8 to the 220 which is 3.0 it's ok..but 225 which is 3.2 booting is not all the time. Please help me to overclock my system right...Thank you so much.

Here is pic of my BIOS Soft Menu

Yeah I lucked out and got an ES chip too, but never got around to using it. Ended up instead getting a faster normal CPU. Have a 3Ghz P4/530ES but ended up building my system with a 3.4ghz chip instead and have been overclocking it instead..

Anyway, I had completely forgot about the ES chip in my drawer and decided to sell it to make a few bucks to buy some more upgrades... Not sure what to get yet, but I'm sure I'll find something...
Heres a link to the uncensored version of the Ad if ya interested:
http://www.wolfstartradingpost.com/A...UNE/P43GHZ.htm
from there u can get to the auction if ya want..

Hey, I also have an AMD es chip somewhere, are they special in anyway?


Anyway, off to another message, have some questions of my own to post.
