Is this a good clock?

[HazzyP]

Hi guys,

been reading pages and pages of "how to overclock" stuff and other peoples clocks and how they have achieved them.

what ive noticed is my chip seems to get decent clocks on much lower voltage (checked on hwmonitor, cpuz, etc not just bios).

Heres what ive currently got, any good?

E8500 (EO step, latest revision) now running at 3.8ghz using 1.20v VCore(bios), 1.17v (in other progs to check), which dips to 1.14 under full load.

FSB - 1.20v (1600, using a 9.5 mult)

Temps are 30c idle, 46c under full load. (OCZ 2)

Passed OCCT, PRIME and ORTHOS tests, all 1 hour on full cpu bashing.

What I cant understand is others seem to be using 1.3v+ when heading towards 4ghz and mine is using precious little.

Am I missing something here or what?!

Cheers.

Sometimes you get lucky and find a superb chip that will happily clock on low voltages. Sometimes you get unlucky and need huge voltage to get a small increase.

I'd Prime it for 24 hours before you consider 1.2v stable though.

You lucky ****.

But for safety you should crank the voltage up to 1.3 or maybe even 1.4.

failed on ORTHOS after 1 hour 20 mins.

pc went in reboot loop and had trouble starting up vista, the blue screen mentioned a usb device problem or something.

reset the bios and now im back, try again eh!

more volts!!!

Yea sometimes overclocks can look good around the hour mark but it's best to do at least 3+ hours if not 24 hours being the best test.

Sometimes you can get lucky on voltage and sometimes not,my e8400 does 3.6ghz with 1.216V and 3.8ghz with 1.225 volts for 24 hour tests without a problem. Will be going higher when I get my new ram soon and see how far it can really go.

Now stable for over 3 hours (prime & orthos) @ 4ghz using 1.22v.

Temps are now mid 30s to low 50s idle and full load mind!

Not bad!

Thats not a bad overclock pal. I will agree with Darkjeste though. 24hours is the best test for overclocks. I still recon you up the Vcore voltage to 1.25 maybe 1.3V for ultimate reliability.

All depends on the VID of the CPU. Whenever you're increasing those overclocks the voltages required start increasing a bit higher than a linear path. That said you've got an E8500 E0 so I think you'll be able to hit 4GHz (maybe more) easily on air cooling/decent volts.
