Hey guys,

So I managed to snatch an i7 2600 (non-k) from a relative's HP for free, which was a decent upgrade over my fx-6300. Now, I want overclock it, but I can't. I've already upped the multiplier so that it'll run at 3.9 ghz all threads and 4.2 ghz single core. Now I'm looking to push the BCLK. What's the safest I should have it at? I have it at 102.6 right now so I can *just* reach 4.0 ghz on all threads, and I don't feel like I should go any higher. Should I keep this or bring it back down to 100? I'm honestly afraid of my components (mobo, hdd, etc) dying. Another option is that, I have a friend who doesn't OC but has an i5-2500k, and I think I could trade him, but would that be worth it? I would be able to get the i5 higher but would the larger cache and HT in the i7 make up for the ~0.5ghz OC I should be able to get?

Thanks in advance~!

Rig:
i7-2600
Asus P8Z68-V LX
Corsair Vengeance LP 2x8 GB DDR3-1600 (OC to 1866 10-11-10-30 @ 1.65V)
R9 380 Nitro (OC to 1140/1550)
Adata SP920 256GB

As I recall. BCLK overclocking has a potential of 1-3%, hardly worth it.
There are too many interdependencies.

Few games can use more than 2-3 threads, so changing to a potentially faster I5-2500K seems to me to be a good idea.

Isn't that what overclocking is about? Getting the last drop of performance out of your hardware?


That's what I'm afraid of. Do you know what a safe range of BCLK OC would be? I don't want to burn out any components.


Yeah, that's what I think, too. But are there any benchmarks that compare the i5-2500k @ ~4.5~ghz to a 4.0ghz i7 2600(k)? I want to make sure there really is a difference before I upgrade, but looking around online I only see 2600k's going at 4.4+ghz
 
To see how many threads are useful to you, try an experiment.

You can do this in the windows msconfig boot advanced options option.
You will need to reboot for the change to take effect. Set the number of processors to less than you have.
This will tell you how sensitive your games are to the benefits of many threads.

This won't exactly make a good comparison since it won't show the difference in clockspeeds and cache, but this does make a good baseline for comparison if I were to swap it out. I'll have a look at it. Thanks man~!
