Specs: Windows 7
Hi guys, I'm new to OCing and wanted to
check that I was heading in the right direction
before buying the rest of my computer parts.

I am aiming for a budget Gaming rig capable
of playing the newest games such as MW2
on moderate graphics (@720p ideally because
im using a 32" tv as my monitor :P ).

The rig I was aiming for was:
AMD Athlon X2 250 3ghz (already have)
MSI 770-C45
G.Skill Ripjaw 2x2GB KIT: DDR3-1600 PC3-
12800 CL9-9-9-24 1.5v (already have)
Nvidia Geforce 8500gt (already have, though I
will probably replace with a geforce 250 or ATI-
HD equivelant in a month or 2)
X Power 450TD PSU (already have): a link
here to stats: http://www.compucase-
Enermax Pandora Case (already have)

Well thats it, probably not too impressive but
will hopefully do the job. Firstly i'd like to know
if them parts would be fully compatible or if i
would have to buy a different board (hopefully
also around £50 like the 770-c45) or buy a
different PSU, especially if I plan to OC the
cpu from 3ghz to around 3.6 or even 4 if the
setup allows.

Secondly would the stock cooler that came
with the proccessor be enough for either 3.6 or
4ghz OC or would I have to buy a seperate 1
(and if so could I get away with a cheap £15-
20 one from someone like Coolmaster)?

Lastly, If the 770-c45 is good enough, it has
an easy OC swith i think for up to 20%, would
that effectlively OC the processor to 3.6ghz or
not (and of course does it even work well)? if
any1 with experiance of this board or similer
could comment that would be great :)

Thanks for reading and any input would be
apreciated. Thankyou.

The power supply will have to be replaced. The unit you have is spec'd out poorly...too much amperage on the +3.3v & +5v rails, not enough on the +12v rail. You'll need a PSU with at least 30A on a single +12v rail & the +3.3v & +5v should be closer to 20A.

The RAM will work but will run at a reduced speed. And of course, the 8500GT is crap. Overclocking should be done manually, not with an "easy overclock switch". There are numerous settings that need to be adjusted for the CPU, RAM, HyperTransport, PCIe, voltages, etc. I highly doubt these settings are addressed with a "switch". I think 4.0GHz is overly optimistic though. Stick with the stock cooler for the time being. No sense wasting money on a fancy cooler if it's not necessary.

thanks for the extra info jam, do you think something like this
would be good for the psu?
It seems to sell for about £40

And as for the ram, you mentioned it would run slower, do you
mean it will run at 1,333 instead of 1,600? on the specs on
the motherboard it has 1,600mhz listed but with (O.C) next to

Is there anything I can do to increase it or mabey consider
buying a different mainboard. or is it worth just leaving it, im
not sure how much difference that extra speed will make to

Thanks again for the help :P

Corsair cmpsu-400cx is the fine psu go 4 it. As jam said 8500gt is the crappy card replace it with hd 4670. The motherboard is fine. The memory controller is located inside the cpu not in the motherboard.

Agreed, the Corsair was a good choice. And as kuwese pointed out, the memory controller is built into the CPU, not the motherboard. It only officially supports up to DDR3-1333 so your DDR3-1600 will default to that speed. But you will be able to bring it up when you overclock.

Does any1 think I can get away with a cheaper PSU (I know
£40 is pretty cheap already). For £30 I can get a SilverPower
400w that seems fairly solid (although it has 2 12v rails is that
a bad thing?)

or even a ColoursIT 400W for just £15 from dabs value stuff:
Im not sure if any1 has tried this firsthand, it just seems a :P also ive heard some1 say its rubbish but
without any reasoning behind it.

if neither of these are any good ill just go with the corsair, it
just means ill have to wait another month to get my computer

one 1 further note...could my system (including a future upgrade
to something like a hd 4670) run off a 350w PSU? id like the
extra 50 anyway just incase but would be nice just to know

When choosing psu look for +3.3v,+5v,+12v rails, how much amps they hold, especially +12v why? Bcause +12v rail feed power hungry components like cpu & graphic card. Single +12v rail is always recommend over multiple +12v rails why? If psu has 2 +12vrails(+12v1@16,+12v2@18) one of the +12v rail is feeding cpu so it's trapped, u only got the second +12v rail to feed the entire system including graphic card. Another thing to look is efficiency, the higher the better. And don't go cheap with psu, cheap psu can fry the whole system. Now compare corsair psu with your cheap psu's

i have seen hd 4670 running on 250w oem psu.
