A CPU overclock of 64% yielded Sandra Arithmetic and Multimedia benchmark improvements of 63% and 64%, respectively.

Optimized memory settings resulted in a Sandra Memory Bandwidth improvement of 77% over default values.

At 1.40 volts, the overclocked Pentium E5200 required an average 34% power increase.

A performance increase of 64% with an average power increase of 34% allowed the overclocked E5200 to improve its efficiency by 22% over stock settings.

    i like these "how to" articles but i still want to see the rest of the twkr article you promised us (quad crossfire 4890's) *sigh* a man can dream can't he?

    Surely people on a budget (like me) would prefer their e5200 to last longer than a 'few months or hopefully a yr to 3?' i know i will upgrade prob in a year or so, so a yr would be fine, but a few months? Pfffft. my proc vid is 1.225 and for 3.33ghz i need a vcore of 1.385 in bios which at idle is 1.36ish. So although im nowhere near 4 at least i wont suffer from electromigration and have to fork out for a new cpu! Just my 2 cents

    Thats obviousl 4ghz not vcore lol

    It's all a game of averages. Tom's Hardware hasn't accidently killed a processor by overclocking it in a while, though I'm sure a couple editors have intentionally done so to find the voltage limit. The problem is, once again, you can only look at averages.

    3 months continuous use at 1.45 volts caused an E8500 to lose its OC stability. It had to be clocked down to become stable again, and lost much of its voltage tolerance. It wasn't destroyed however.

    1.40 volts should be significantly safer than 1.45 volts, but until a few people report on how long their cores lasted at 1.40 volts its impossible to tell "how much safer", that is, how much longer it will last. All that's known is that it should last "significantly" longer, but whether that's 4 months (33% longer) or 30 months (10x longer) is the unanswerable question.

    Good show mate.

    I would have liked to see combined charts as a conclusion but that's a minor criticism.

    I'm just wondering what the 'next-gen' E5200 (i.e. the intel people's OC'er) will turn out to be? Some flavor of i5 I assume, but who knows.

  • how is it that im running my q8200 at 3.04ghz stable at 1.25v? weird

    "Intel’s value-priced Core 2 Quad Q8200 uses two of the same processor dice as the Pentium E5200....."

    I don't know why you choose the Q8200 it's a notoriously bad overclocking chip, if you wanted a budget Intel Quad core that had room for overclocking you should have bought the Q6700/Q6600.

    MSI P45 Diamond is not LGA1366, but LGA775. LGA1366 is for Core i7 processors only, LGA1156 is for Core i5 and i7 (only dual channel DDR3-1333/1066). LGA775 is the old socket, for Celeron D, Celeron 4xx, Pentium Dual Core, Pentium 4, Core 2 Duo, Core 2 Quad.

    No games? Like...none at all? Does anybody even overclock for reasons other than games?

    Otherwise, pretty good article. Though perhaps a better choice for the Intel quad would have been a 9550...I thought they were under $250 by now. Same time, I guess the Q8200 does seem to be a more difficult overclocker...Intel may have intended this to be the case so as not to gut sales of their Q9000 series. And readers may as well know before jumping on a Q8200 thinking it'll overclock like an E5200.

    I agree. Q6700 will reach 3.6Ghz with no problems.
