Noticeable Difference Between 4.5 and 4.8

post #1 of 9
Thread Starter 
I was able to get a stable overclock of 4.8 (prime95 for 10 hours), but the vcore max is 1.4v according to cpuz. I have heard that asrock boards tend to report a different voltage than it is actually getting up to 0.1v more. My temps are fine, but I am concerned about running it at 1.5v under load.

Is it worth the risk for 300mhz? Btw 4.5 runs at 1.34.

I run my 3770K at 1.62v for hours at a time.

I think you will be okay under about 1.45 for 24/7 so long as your temps are in check.

Meaning the board shouldn't be fluctuating by enough to be dangerous yet.

However if you plan to keep the extreme4, invest in a multimeter for overclocking.

What cooling are you using? I'm at 4.8GHz, 1.40v with my CM 212+. Honestly if you're on air, you're NOT at 1.50v.

My 2500K was 1.52 24/7 as well... under a Megahalem. on a z68 extreme3.

You guys are both okay for a ways to go. I would even call it headroom. :]

2500k puts out a LOT less heat than a 2600k though. I had my 2500k at 1.60v 24/7 under a modified H50 for over a year. On air, I had her at 1.52v (I had a really REALLY bad 2500k).

With HT on at 1.40v, I'm hitting 90*C on my sig rig which is too hot (I like to see 85*C or less). Same cooler two years ago on my 2500k at 1.40v I'd be at 60*C load, lol.

Thanks for the replies, I guess I won't worry too much. I am on air and have a Zalman cooler. In prime95 it stays under 80c and in games always under 70c.

Yeah, you're definitely not at 1.50v then. I'd believe the 1.40v that CPUz is reporting in this case. Your temps and voltages are more than safe.

Thanks again for all the input. I'm going to stick with 4.7 just to be extra safe, but no one really answered my title question.

At 1440p with my system, would there be any performance difference in any game between 4.5 and 4.8?

because of SLI, perhaps.

it will help your cards communicate faster from my understanding. Which will help level out frametimes.
