3.0E Prescott OC Question

I just bought a 3.0E Prescott (EO stepping). Its running on a Gigabyte 8IK1100 Rev 2 with the newest Bios(FI), 80 Gig Hitachi SATA HD, 9800pro, 1 Gig OCZ PC3700EL with a 470 Watt Raidmax Power supply.

My former chip was a 2.4C Northwood which would run at 3.12 Ghz @1.53volts at 265 Bus speed.

I just replaced the chip and i can get my new chip stable at anything over 3.3gig. Ive raised the voltage to 1.5 and it still isnt stable at anything over that speed. The chip is idling at around 37-39C.

My final conclusion is it has to be the chip, but i was pretty sure most E0 Steppings were great OC'ers.

Has anyone had any similiar problems or am I correct in that I just recieved a bad OC'ing Chip.
 
prescotts do put alot more stress on motherboards than northwoods will because of the extra power requirements and increased heat buildup.

Also prescotts like to be cool, I have a 2.8e for example and take a look at this

Stock Cooler 14x230 = 3220mhz 64c Load @ 1.4v (no benefit from increased volts beyond this point)
Coolermaster Hyper 6 14x245 = 3414mhz 51c Load @ 1.56v (1.5 actual)
Watercooling 14x258 = 3612mhz 42c Load @ 1.56v (1.5 actual)

those are all from my 2.8e. Prescotts love to be cool but are just damn hard to get cool
 
I was running a Thermalright XP-90 with the 57 CFM Panaflo can on it, and at load it was running in the mid 50's.

My power supply is more than enough to power my PC and the sheer fact that is needed a extra .1 volts to gain 300 mghz makes me think its just a bad wafer.

Its cant be the mbo since it used to run at 265 110% stable its not the ram or HD, or Video. So i must have just gotten unlucky and got a bad EO Stepping (which i didnt think existed)

Oh well ill sell her on ebay and buy a 3.2E and hope for the best next round.

But if anyone else thinks they can help me or that they agree with me please reply. I'd like to collect all the info i can....

mind telling me where you got your prescott, im planning to get one with an EO stepping.
:)
 
I currently run a 3.0E until later tonight when I pick up my 3500+, but with my Thermalright XP-120 I can't push the chip past 3330MHz... It just doesn't like it... My old liquid setup that I sold to a friend, couldn't do anything better to his 3.0E or push his new 3.4E past 3.86... I just am of the opinion these chips aren't happy OCers... =[
 
I bought my 3.0E at ZipZoomfly.

So I suggest buying one from elsewhere. Its was brand new boxed (E0 Stepping too)

It just wont run any higher than 3.34 and thats at 1.53 volts which is what i ran my old northwood at which oc'd about 800mghz.

Like i said i must have gotten a bad chip. Ive been oc'ing and building comps since 1999 so i sorta know what im talking about. I just need some info to back up my thoughs.


Thanks for posting guys, I appreciate the info!!!!
 
go with the 3.0c its a much better overclocker...my 3.4E sux for overclocking

Have you run the motherboard with a prescott though?. Ive tested a 2.4c in my current motherboard and it did 270fsb. Doesnt mean any prescott I get ever will. Prescotts put more strain on the board. Especially a board in your case that was probably never designed with the prescotts in mind. (dont worry most 865/875 boards wernt, including mine, but most still work fine).
