Today I just picked up my core i5 2500k from micro center I am going to be installing it this weekend when my ram comes in that I ordered one newegg.
I got it so I could overclock but I don't have much experience here I know some of you guys are familiar with it mind helping me out a bit. Any advice is appreciated.
Motherboard: Asus P8P67 Pro
first thing to do is download the newest bios and flash your mothervoard as soon as you get it.
fiddle around with the settings but make sure you dont manually change the cpu vcore above 1.35v.
there is a tonne of info out there, esp for the asus boards as they are popular

also the heat generated by the cpu is linked with the voltages you're passing through the cpu. after installationa and when everything is stable, go through some cpu burn tests and keep a close eye on the temps, scale it down if its too high (below 80degC)
I've overclocked my 2600k to 4.5, but a 2500k is identical:
Just raise the "CPU ratio" to 45, and the "Core voltage" to roughly 1.275 (increase it by a few notches if it's not stable)
Disable turbo boost if you want your overclock to stay constant (I've got mine disabled)
Overclocking sandy bridge is so easy, 45 ratio obviously means your CPU will run at 4.5GHz. Nearly every chip can reach 4.5GHz, so you might as well immediately raise it to 45, instead of stepping up gradually. And of course your BIOS options may be worded differently.
That's all there is to it!
Thanks for the info I will look through links when it comes time to overclocking it
One more quick question regarding ram. I am looking at getting 8gb dual channel DDR3 1333 G.Skill
This is one thing I have never really been informed about, but should I be looking at higher clocks, and doesn't ram have to do something with how far you can overclock a CPU.
This may be wrong but I just need a clarification.
Ohh and does anyone know a good aftermarket cooler for these CPUs
hey hopkiller, 1333mhz is a.o.k for sandy although stick to 1.5v for a ramkit do not buy 1.65v ram unless they're clocked for 2000mhz+ if i had a choice between 2 different kits both at 1.5v one of them 1333 and the other 1600 and the difference is minimal in price, deffo go for the 1600mhz. there are some test somewhere showing the differnce between these frequencies, however the effect on extracting winrar etc is very minimal. for snappiness, fiddle with the memory latencies, the good thing about the higher clocks is that you can downclock them but tighten up the timings
sandy does not touch the frequency as the baseclock is fixed at 100mhz, some people change it to 103mhz (changing it is pretty limited), but its not worth it
edit: have a read through this article,

wrt to cpu cooler, i can only recommend to you the nh-d14. you know the old saying, if you buy cheap, you buy twice.. this is one of the best aftermarket cooler and the design and construction is fantastic, oozes quality
This is the ram I am looking at I can get it for 65 as I got a code
G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666)

lol, surprisingly its cheaper than this,

get it, nice price.. americans are so lucky, electronics are so cheap over there :/

Damn right. I'm jealous of their prices.
^the chinese connection and petrodollars :3

I'd personally want to get something with lower timings.
As for cpu coolers, definitely look at the Noctua NH-D14, Thermalright Silver Arrow, Cooler Master V6GT, and Thermaltake Frio.
The Noctua and Thermalright are the best coolers on the market right now, and the Cooler Master and Thermaltake don't fall too far behind.
How much of a performance increase would I see with the increase timing of this ram
Is it worth the extra $25

all that extra $25 dollars spent does is gaurantees those low timings, you could do that yourself, but thats where you'd be playing the chip lottery. performance in terms of bandwidth, v. minimal change, but the timings just gives you a more snapppier feel, but and its a big but :B theres a peak in snappiness, tighten the timings even further and the reverse happens ultimately crashing and artefacts.. so is it worth the extra 25 bucks, imo no, just view it as an overclocking perk
have a look through this too,

I'm not sure how much of a performance difference there would be, but ram with lower timings will usually be faster than higher frequency ram with higher timings (depending upon the difference in timings anyway). Also, just keep in mind that if you buy ram with higher timings, you're probably not going to be able to manually lower them and have them still be stable. I'd spend the extra money, but that's just me.

But doesn't to low of timing corrupt data?
for sure, but for those ram modules, you would be paying the premium for cherry picked pieces and the ability to overclock them further are minimal as they would most likely be using kits with the same chips (hynix etc.. dont really know what g.skill use underneath those heatsinks).. that $25 could be better spent elsewhere
faster in terms of extra fps in game is minimal but fiddling with the timings and the effects within windows, for me that is, i see that my system is a bit more responsive
to the OP, if you can the sweet spot for sandy is 1600mhz cl7 1.5v
