Here's an easier to read summary of the thread:
- the VRMs on your board aren't sufficiently cooled. These are what the power flows through, and they get hot. Your board lacks VRM cooling making it impractical for overclocking. As well, your board doesn't have very many power phases ; these smooth out the power being sent to the CPU.
- Your chip is a C2 revision ; it doesn't overclock nearly as well as the C3. The C2's are notorious for having trouble reaching 4.0GHz.
- We suggested, with your budget of $250, to get an AM3+ board better for overclocking with a 960T zosma processor. The AM3+ board permits you future upgrades, namely Bulldozer [8-core processor, which goes past 4GHz+ easily]. The 960T is a Thuban processor, which is 4-cores but can be potentially unlocked to 6-cores. Even if it doesn't unlock, it'll still overclock much better, it's a higher quality chip.

TL;DR You have a crappy CPU/combo. Good in theory, but the specific revison + board were poor quality. So get a new 4-core [possibly 6] processor with motherboard for under $250 and have the possibility to upgrade to an 8-core when you need it. They'll most likely be around $100-120 when you'll need to upgrade.

Thanks for your response. However I was more confused about the processor I should buy, whether the 960T or the other one. But again - thanks for enligntening me smile.gif

And again, thanks for your time, for helping a noob as I am smile.gif

Why has nobody mentioned the 2 most important problems with the OP's machine, except Shmuckley?

1) Your motherboard can't handle an overclocked 125w CPU with the VRM design it has.
2) You NEED a replacement power supply, one of quality. Even a Corsair CX430 would be a HUGE upgrade in stability for your voltages....and a ton safer.

Buying a whole new board/cpu seems a waste of $250 though for what is essentially a chip that is otherwise operating perfectly well, albeit doesn't hit the magical 4.0 mark.

That is the length hardcore clockers go to I suppose...

So Chieftecs are bad power supplies? o_O

I am asking because from what I have read when I was buying parts for my PC, it had preety good reviews and in the end I paid about 90$ for it.

My friend's Vega had a 400 BB in it..bored and stroked ..with 2 650 Holley carburetors tongue.gif

Idk what reviews you read about that Chieftec psu..don't feel like searching through browser history..but umm..the ones i read were not favorable

try a rosewill green 530 or 630,Thermaltake tr2 series,Silverstone,Lepa,Seasonic,HEC high-current ..or..derpa derp ..Corsair

500-850w

I also brought up the VRM cooling + lack of power phases but ... oh well? I guess you overlooked it
The PSU is a problem, but it's further down the list


PSU is the most important component in a computer.

Schmuckley I bet a stock vega wont out perform your friends vega

So I think the bottom line here is.
Get a new PSU to start. Then decide if you want a new motherboard/cpu combo. If you can handle having a lower clocked chip right now, you could save up and get something like a 2500k or whatever is availible for Ivy when it comes out. That would be the better option. I personally would get a new PSU and then save and get intel.

or if money is tight a good deal can be found here at OC on used mobo,cpu,ram and psu not new but a diffent upgrade
