remember not all processors or mobo's act the same as others or even if they are the same... in other words other people could probably go way higher than you stable or way lower than you stable... its simply just *Pure Luck* ... but wte That was back in 2008 *2 years ago... no clue if that guy is still around to ask (pretty sure that guy had good water cooling) =P but anyways that is really good overclocking where you are at.
Anyways jumping out of subject....
Guys buuuuuuuuuuuuuuuuuuuuuuuuuu I hit a Huge BUMP!!! I'm pretty sure its my crappy PSU(I hope), because I've been a few days running 4.21Ghz since the very second day of having the H50 stable(did prime95 blend overnight & had also ran Intelsburntest maximum ram 7158mb 5 tests stable & my temp max load was between 50c - 54c, but that was only 1 time i tested them @ that overclock)... well today randomly it started freezing / then I rebooted decided to run Prime95 to see if its all okay... in just only around 35 minutes all the sudden Temps reached around 60c and my PC crashed (turned off, no reboot - power button didn't do anything - i had to unplug wait 1 minute and plug in again to turn it on)
So right after it started, I head inside Bios, set everything to default stock @ 3.41Ghz (200 x 17) made my voltage, rams & everything to Auto. Booted up and ran prime95 again on blend ... no clue but Temps were going way high to around 57c (noticed through Everest the Auto cpu voltage was going up to 1.52) ... so decided to stop reboot / Bios this time setting manually voltage starting from 1.400 booted back into windows this time decided to use Intelsburntest (since its faster for 100% cpu usage & ram is used allot too) same maximum ram 7158mb, 5 tests... this time its max was 52c (its way too high compared to when before, when i used to be on Air cooling - comparing to now having the H50).. so I said wte...
Its time to start all over again overclocking, just leaving the cpu voltage manually @ 1.4 and just only alone changing the cpu multiplier & limiting my self that the highest max load temp should be between 55c - 57c... so kept going up 0.5x (testing each time Intelsburntest max 5 tests) until it gets close to those temps & cause a reboot to my system (if it reboots - set higher the voltage, but paying attention to my max load temps)... after a couple of hours doing stable tests.... well for some reason my current max... 3.90Ghz (200 x 19.5) 1.412v idle @ 32c / max load @ 57c <-- that made me really sad
If I even go higher at 4.01Ghz (200 x 20) I have to up my voltage to 4.275 to be stable(it crashed my system a few minutes on testings @ 1.4125v) and my Temps would reach over 58c probably 60c but I stopped it.. that is way too high so lowered back since for me the one before were reasonable temps for me (even if its still hot, pretty certain i won't run anything nearing close to 75% cpu usage <-- thats around 48c - 50c)
so yeah I'm stuck bumped at 200 x 19.5 - 3.9Ghz - 1.4125v
Now hopefully, when my new case arrives CM590, adding all the fans in all available mounting spaces & upgrading my PSU, then I should be able to go higher again over 4ghz stable(and obviously have lower temps).. if not.. pretty certain that could be my Phenom heading to death *over heating* & I should only run it at stock or lower. *Also I would re apply thermal paste again.
