well i have a intel e4500 2.20ghz i over clocked to 2.60ghz and if i go anymore my pc crashes, my multiplier is at 11x thats default. my fsb is at 946, and core voltage is at 1.160v.
anyway im kinda confused my friend told me to mess around with voltage and mutlipler but idk i dont really trust him. i got to 2.60ghz from 2.20ghz just from changing the fsb. my motherboard is a nforce 630i then heat sink/cpu fan are stock they came with the cpu. my ram is 2gb 2x1gb pc2-5300 (333mhz) crucial technology. i don't need anything from my ram, i just want to over clock more i read that the e4500 can go to 3.0ghz very easily but i cant really go any high because my pc crashes can someone help me with multiplier/voltage and stuff?

i have my multi at 9 and fsb at 333, no voltage change

its super stable, i downclocked my **** ram to 667mhz, and my fps in every game almost doubled

i have a maximus formula x38, maybe your mobo won't reach these clocks, but no reason it shouldnt

ive read somewhere that 333bus should be your low because anything lower than that drops your performance per clock... even if you manage to get your multi to 10, and bus to 300

so theoretically, your 333bus at multi 9 should be faster than 300bus at multi 10, even if it is a small amount

Raise the core voltage, it took me up to 1.3v set in BIOS to get my E4400 to 2.8GHz(1120MHz FSB) fully Prime95 stable. Intel says the acceptable voltage range for an E4500 is .85v to 1.5v, but 1.5v is pretty excessive for a 3.0GHz overclock. I'd try setting 1.3v and see what luck you have with getting up to 2.8GHz, and see if you can push 3GHz. With my E4400 I needed 1.35v set in BIOS to get 3.0GHz entirely stable(1200MHz FSB).

^^^??? i got to 1333fsb without changing voltage on my e4500... and a clock of 2997mhz, which is a pretty high oc without any voltage change, dont u think? and ive heard of people hitting the oc wall for this proc around 3.6...this is pathetic compared to today's 45nm

at the moment im doing a cpu stability test its been running for 8 minutes no problem. also i had the blue screen of death when overclocking.

Different motherboards have different default voltages, as Intel doesn't give one set default voltage, but a range. My board also seems to have particularly bad v-droop(actual voltages lower then what is set in BIOS) and my CPU after double-checking is also an older stepping, the E4500s weren't made until the M0 stepping, but my E4400 is the older L2 stepping. This is probably what causes the difference. I also have a 10x multiplier set, you said you had a 9x.

Looks good, but you really need to run the test all night to be sure it is fully stable, but your temps look fine

yup its fine so far, its been running for about 4 hours no problems. i got to 3200.0 mhz fsb is 1164 multiplyer is at 11x and for some reason i set voltage to 1.300 but its at 1.264v by its self, and a idle 45c.

um....after 5 hours of being stable it crashed...and a blue screen poped up and it said physical memoery dump i restarted my pc and set bios to default and it went away? should i inscrease my voltage?

i have a 11x multiplier set, i lowered my multi to increase my bus speed, thus maximizing my overclock without upping the voltage

question: vcore in bios is 1.296v, and vcore in cpuz is 1.296v...so i have no vdroop?

my board is a maximus formula x38

i just saw it go to 1.304 in cpu-z....??? so my vcore goes up instead of down?

i found a link, whats load line calibration?
July 31, 2008 11:28:34 PM

I'm not sure, I've never had a board with an option for load line calibration. My board is a P5B-Plus, so it is much more of a budget board then yours, and therefore doesn't have as good of voltage regulators.

danik6, the reason your voltage goes down is that many boards do have vdroop, where the voltage you set in BIOS isn't the voltage that the CPU actually gets. Increasing your voltage may help stability.
