Just wondering, how much could you OC a phenom II 1045T using only a stock cooler?
and how much more will you be able to OC with 2 cores disabled?

and one final question, what program should i use to record cpu temp. and power usage? (i tried using core temp, but i don't think it's too reliable)

Never oc on your stock cooler. A hyper 212 would be a great cheap choice. Use hwmonitor for your temps.

the 1045t is not a black edition cpu so OC will be limited.

I wouldn't advise trying to overclock on the stock cooler, mine barely kept my 1055T cool at stock speeds.

so at what temps should i stop upping the frequency to prevent damage?

at stock, it goes up to 43 degrees C, but with 2 cores disabled, it goes to 3.2 Ghz with 40 degrees C
(after 20 mins of 100% load)

keep it below 60C at max load.

ah thank you :) 

just to make sure, is core temp unreliable? it says that the temp of the CPU was at 30 degrees when i turned it off, but when i checked the BIOS, it said that my CPU was at 59 degrees? has something gone wrong here?

that can't be right. Try speedfan.

will do as soon as i can. (i.e. tomorrow morning)

What is your vcore set at? Make sure its not on AUTO.

i don't actually know. would i find it in the BIOS?

also, is it the core temp. i should be looking at?
the core temp is at 24 degrees (idle) according to core temp, hwmonitor and speedfan.

Yeah it is in the BIOS under vcore or something along those lines. I ask because my mobo had my CPU on auto vcore and thus made it run way too hot, once lowering the vcore I could overclock.

ah i see, how much should i decrease the vcore by for each time i increase the clock speed by (a general estimate. otherwise i'll just decrease it by too little/ too much without knowing what the hell i'm doing)

I'm at 3.2 ghz stable on all six cores with the factory cooler. Temps max at 55C and usually sit around 53C. I'm not saying keeping the stock cooler is a great idea, but it's do-able. Upgrading mine this weekend :D

Is this an OEM computer like mine (see my sig). I was under the impression that the 1045t was made only for OEM computers like my HPE 410y. If that is the case and it is a OEM computer like an HP, Dell or Acer with a stock OEM motherboard then you are not going to be able to overclock the CPU. Big box computer companies lock their BIOS so they can't be overclocked. If you have the 1045T in an aftermarket motherboard then it can be overclocked but because it is not a Black Edition CPU it wont ovetclock more than a few hundred MHz. It runs stock at 2.7 GHz and you might get it to somewhere between 2.9 and 3.0/3.1 but thats probably just about it. You arent going to get it to some crazy overclock like 3.9 or 4.5 GHz.

My brothers 1055t is happy to be sitting at 3.5 Ghz with the hyper txt3 (212 required mobo removal, and I was lazy :p ) running at less than 55c with prime95 nuking all cores.

So a 1045 should get to 3.2/3.3 np. As far as stock cooling goes, if you have the better of the two heat-pipe coolers amd ships, I would say you can get to 3 ghz easy, especially if you lower voltage by 0.025v

I have a phenom II x 4 925 Deneb stock 2.8 OCd to 3.4ghz
I use a AMD dual heat pipe Phenom BE-edition with 60mm fan
I also OC my HD 5770

My temps with Prime95 64-bit CPU stress test with Furmark GPU stress both running
in a 69F room after half hour
CPU max 54c
GPU max 72c

but that is with a total of nine fans including PSU and GPU fans

I also rigged the wiring on the CPU HSF to run up to 5000 rpms

so it is doable
of course since it is not a BE it is harder to OC

this is a guide to OC AMD Phenoms that also includes Thubans

trickier to OC without BE but you can still get between 500-700mhz increases on average
