Overclocking intel e2180

Last response: in Overclocking

I got e2180 and asus p5k mb, and for cooling putted igloo 5060pwm. Got 1 GB DDR2-800 5-5-5-18 (a-data) (no ddr2 near by at the moment so i just borrowed this ;)  )
Overclocked it on 2.66 with no problems and all i hear is my hdd running :)  (i just changed from 200 to 266MHz and left all else to auto)
Want to overclock it on 3.0 or more ... so can someone say should i put more voltage or to leave it on auto (i see it change depending on the loading on the cpu)

Tried to clock it on 3.0 but seems i have to play with voltages and a lot of other parameters that i don't understand, because it refused going with auto settings on those parameters i said i don't understand.

Anyone? :)

Post the exact specs here. Screenshots or text.

If you post your bios settings, it'll take me less time to get to the bottom.

as for bios ill take some pictures and put them here

Boot to Windows, do "Super Pi Mod" 2MB (google)
if it fails, back down a notch in FSB i.e. 395 & try again
if it passes, up FSB by 5 & try again

Your cpu fan is average. If your case cooling is weak, you won't o/c very high.

i dont know how to upload the pics
maybe to send them to email or smth?
or skype ... or anything :) 
or how to put them here?
October 9, 2007 3:20:05 PM

man, if you ever come to macedonia, i bye you a beer ... at least :D 
now going to check how it will go :) 

October 9, 2007 8:30:25 PM

damn, it just dont like that. tried reducing fsb and again and agian but its not booting at all like that.
maybe to try another pice of ram? or it should not be the problem?

Burn this as image on CD/DVD:

Reboot, enter bios, load defaults, save & exit. Let memtest run for 5+ passes. If there's any error, your memory may be faulty. It has to be replaced.

If no errors, overclock it again starting at 333 FSB. Set DRAM Timing Control to AUTO. Do SuperPi 2mb. Once you reach a stable o/c you want to keep, do memtest+ & other programs for 8+ hours for stability.

Done evrything,
it wont overclock at any other speed but 2666MHz

maybe thats my luck?
or mayeb i should try with some better powersupply? Current is 420W, maybe i need stronger than this?

the problem is your mobo, at 266 bus speed, that brings your fsb up to 1066, thats the highest your mobo can do(as far as i know, a mobo with 45nm support (1333 fsb) would be better for overclocking. thats just my two-sense, the only experience i've had was with amd cpus, witch use hypertransport (much faster).

edit- after some research, it seems your mobo CAN to 1333, im fresh out of ideas.
June 7, 2008 1:52:11 AM


That makes absolutely no sense....especially "amd cpus, witch use hypertransport (much faster)."- lol

The P5K is rated at 1333 and Overclocking generally means pushing the mobo past spec.
Edit: saw ur edit^^

Edit 2: I got to say its the E2180 themselves. I have one and based on others they are limited in OCing compared to the E2160. Its fine but at 3.0+ it starts to get VERY power hungry and eats vCore like nothing. Play around with some stuff....raise vCore. Leave NB alone

If u want drop the multi. and raise FSB to rule out cpu. That will test mobo and ram
June 7, 2008 2:15:17 AM

the limit of the E2180 is about 3Ghz and 3.2Ghz being the max on P35.any above prove to be very hard to do.

on my 650i i can only push as far as 3Ghz with 375x8,any more will just fail in prime.just to let you know E2xxx is the worse yield Core 2 chip thats why they get speed bin to be the lowest series in the Core 2 family.

^+1 for limit. Yes indeed you will be limited to max of ~3.2Ghz with out increasing voltages above 1.5v. You need 1.54v to hit 3.3Ghz stable 6hrs on Prime95.
June 8, 2008 8:39:47 PM

Normally, yeah.

And iluvgillgill, that 659i isn't yours. :p 
June 8, 2008 11:15:37 PM

shusssssssssh evilonigiri!!!neither its yours!!!
June 9, 2008 1:41:24 AM

i think u'd better check your ram,my friend have this cpu too.
fsb 266 ram auto ,ok
fsb 333 ram auto,ok
fsb 400 ram auto,fail!
so i change the ram to kingstone ddr2 667 1GX2,they can got 1100MHZ in 1.9v,this time ,fsb 400 ram auto,ok!
i think u can try to turn command rate 1T to 2T.
by the way ,mb:colorful p35x7 90$ ram:kinstone ddr2 667 20$/per
June 9, 2008 3:42:26 AM

well booted in those speed isnt impossible.but has he done 8 hours of prime to make sure its stable?i have done way higher speed than those you got.but it would just fail in stress testing.which it is pointless for you to point it out if it cannot be use everyday.
June 10, 2008 5:36:01 AM

of couse i did,400X8 FSB:MEM 1:1 RAM@800 1T
3dmark06 cpu test 5 times
games hl2 crysis quake4 doom3 war3 5V5 RPG (its the most popular in China,so,u know,i came from China).
all pass ,nothing wrong with it.
by the way,EIST ,u should make it disabled.
June 10, 2008 1:30:58 PM

haha you know what i came from China as well!whats up my homies!!!lol
its quite surprising to found DDR2-667 able to run at i guess it means that every memory is the same(from same brand) and just the SPD is different so make them run at different speed and timing.

I couldn't get my e2180 past 2.5GHz. I followed the instructions here and it ran right away at 3.2GHz stock voltage. Ran the super pi 2M no problems. Will keep pounding on it and see if it will stay alive. I am very very thankful for the advice in this thread and amazed too. Wow. Thanks.

Actually it is at 1.45 volts and overheating. Sorry about the incorrect info.
