Can you Overclock Intel i5 2500 (no "K") to 4Ghz?

i5 2500 without the "K" is not possible because the CPU ratio multiplier is locked. If you really want to overclock the CPU, buy an i5 2500K, i7 2600K and i7 2700K and a motherboard with a chipset P67, Z68 and up coming Z77 lga 1155 socket. BTW are you a PINOY?

Ignore the post above. OCing a 2500 is not impossible, it's just very limited. Take a look at this table:


But honestly why do you need to OC? 3.3GHz is a decent speed.

Non-K processors have a locked multiplier so any overclocking must be acheived through raising the front-side bus frequency. Since the CPU is not the only component driven by the FSB, it's not feasible to raise it very far at all.

Why would you post that chart and then add a comment like that when you advertise a 4.5GHz OC?

There is no explaination that the chart you posted represents "Low Idle speed, Turbo Boost and nominal speeds". All normal operating paramenters of those CPUs which might not be apparent to a new comer to OC'n.

Because I'm telling him that 3.3GHz is not slow. I OCed because I felt I needed the higher clock speed for what I do. But honestly, I would've been fine at stock speeds.

The non k are locked to a maximum not locked from being able to change. What you are really doing is changing the turbo speed which for the 2500, the max is:
4 cores:3.8
3 cores:3.9
2 cores:4.0
1 core: 4.1
You can go higher changing the bclk, but this will also change the clock for pcie, sata, and other ports so can cause corruption. http://www.channelpro.co.uk/reviews/6511/intel-sandy-br...

Yougotjaked's table are supposed to be turbo speeds but are wrong. Turbo has different levels and each bin is 100mhz so each less core used is .1ghz.

wrong wrong wrong



max turbo + 4 bins is what you can overclock.




false.

This is where I got the table: http://www.xbitlabs.com/articles/cpu/display/core-i5-25... Your actually right however. I found another table with the same speeds you posted:

I agree that 3.3GHz would probably be fine for most folks as well, but that was not what the OP was asking.

k1114 gives a good summation of how there are different ways to operate this CPU, which includes the possibility of raising the BCLK. More in line for what the OP was asking for.

I see you guys are getting together here now.  

I answered his question too though so why does it matter? I told him it's possible, but probably not worth the risk. k1114 just gave a more in-depth reason why...

Simple annswer is NO, not to any useful degree. Just pay the extra $15 and get a 2500K.

Majority of the overclockers don't agree O'cing i5 2500 why? beause it will compromise the stability of the entire computer system. Another reason why Intel manufactures "K" series CPU's.

Ocing the 2500 non k or k is through the same way of changing multi and vcore. I get the feeling you are not reading. You could even oc the turbo exactly like the non k on the k. Majority of ocers don't know that you can actually oc the 2500 through the multi, they don't agree on anything because most ocers are inexperienced. But experienced people will know otherwise. Intel(and amd) makes k cpus to milk more money out of consumers, there's really no difference in manufacturing unlocked cpus, they are just the binned cpus.
