i5 2500k vs 3570k vs 4670k (Stock & OC)

[jacktesterson]

2500K can still push almost any common video card setup out there, especially when Overclocked. (I'm talking dual SLI setup too)

I used to own what that did 4.4 with barely touching the voltage. It's a wicked CPU.

Yep, no doubt about that. 2500k is a great OCer and a great contender, which is why they are still holding decent resale value... I have mine at 4.2 with stock voltage or maybe a slight offset increase I can't remember.

I'm at 4.7 on my 2600K with 1.35V under load. It had been 4.6 for the last (nearly) 3 years. So I'm going in the opposite direction -- testing settings at 4.2 and 4.5. You probably already know already: you can squeeze more out of your processor and still "do no harm." I'd have to check my "prelim tests" to see what voltage was needed for 4.2 with fixed settings, but I already have profile that does what yours does at stock V "auto." I'll want to test it some more, or see if I can actually reduce the voltage.

Still, I'm on the verge of spending some money this year . . . I just shelled out $400+ for a Samsung 840 Pro 500GB. But I'm so satisfied with my ISRT caching setup that I'm now thinking to save the Samsung for the "big project."

After bricking my brand new 4670k, I am reluctant to try and push my 2500k much higher because unlike the 4670k, I won't be lucky enough to be able to return/exchange it for a new CPU. Although, I will most likely try to go for 4.5GHz just so I can get higher CPU mining performance since 4.5 seems to be a joke for sandy bridge

I'm open to (voltage) suggestions :awe:

What motherboard are you using for it?

What motherboard are you using for it?

Asrock P67 Extreme4

edit: I am not using the gen 3 version if that makes any difference.

I was pretty sure from way-back-when that the Asrock was a fairly good board.

If you're running your system at load 24/7, I'm guessing you could do 4.4 or 4.5 and maybe keep the load VCORE under 1.30 to 1.32V. In fact, I'm more optimistic. I pretty much thought the i5 was as OC'able as the i7. I just consulted my notes from summer 2011, and those voltages reflect multipliers of 44 and 45 with bCLK set at 103!! I was already running over 4.6 with those tests.

I left off bumping the bCLCK and set it at 100, starting with the voltages I got from the earlier tests and backing them down. I think 44 and "4.4" is possible -- maybe below 1.30V load.

But it's your own sense of safety that counts. I have EIST enabled at 4.7, and I wouldn't run the system that fast for 24/7 loading.

Still . . . . some here -- IDontCare among them -- think the SB cores were still "safe" at higher voltages. We thought 1.35V was the upper bound of "safe;" a lot of people said "Oh, 1.40V is OK." It just seems to me you won't hurt anything if your load voltage is 1.30 or lower for that processor.

But it also depends on the processor itself . .

Grab a 2500 ,,, non K if you wish to not OC, and 2500k if you want to OC. gl

Either OC or no OC , your not going to tell a difference in games. Who cares about benchmarks and numbers. Play the game instead of doing benchmarks... gl
