My i7 4770k sucks....maybe it's me. - Page 2

post #11 of 22
I would never in a million years let my processor just run wild at 85C for 13 hours....

I'm sure you're likely doing something wrong as you claim you're a brand new overclocker, but why do you need 4.4GHZ for anything? An Sandy Bridge at 4.0GHZ is already fast enough for pretty much any task short of professional computing/digital design.

*Sorry ol'8320, but it is what it is.


I agree there is a noticeable difference. I still love the 8350 for what it was and at the price it was. But the 4770k only cost me 249 at Microcenter so you can't really beat that. About to reboot and test somethings...mainly rung bus (Uncore) to manual.

I'm currently running, 42 multiplier @ 1.2v, 39 cache ratio. I haven't tired for much more, yet. I've since switched to adaptive Vcore, and it seems to be stable, and running well.

This has been debunked in the Haswell guide you linked. Cache ratio has a much smaller performance impact than CPU clock speed so it's better to get an extra high CPU speed with a 35 cache ratio than a slower CPU speed with a 42 cache ratio. Also, adaptive Vcore isn't great, the Haswell guide explains the differences. Personally I'm a fan of manual voltage as you know exactly what you're setting your load voltage to and idle voltage will still be below 0.1 V with C7 enabled.

Sure, if temps are okay. Depends on your ambients and case airflow. Those voltages are only guidelines.

85 C is very high for 24/7, but completely fine for a stability test. It won't get that hot in normal use anyway.

Depending on his monitor resolution and the games he plays, he could need it. I have CPU bottlenecks in some games, particularly those that can't utilize 4 threads like Skyrim, StarCraft 2, etc., but also games that utilize my CPU fully.

The CPU cache Ratio was off of Asus recommendations. I was under the belief that it leads to a more stable OC, and 3 under was a good starting place for stability. I'll check out the 35 you recommend later.

I personally haven't fully read the guide, just the basics. Like I said, I'm still fresh to oc'ing this CPU.

Yea, I'm keeping a close eye on the adaptive power settings. I just don't like the idea of my CPU running 1.2V through itself 24/7. From what I could tell, it's one or the other? Most I've seen at my current settings, is a spike to 1.28 vin / 1.236 vcore. Considering even at stock it was doing 1.27 spikes, I don't think this is too bad right?

35 cache ratio was completely arbitrary. You can set it to whatever (though I imagine performance drops off a bit if you set it too low). Just set it as high as possible without making your overclock unstable to get maximum performance. There are some benchmark results in the Haswell guide which show how small a difference cache ratio makes. I personally used 35 cache ratio and it helped me stabilise the CPU at lower voltages.

No no, if you use manual voltage, it's 1.2 V load (or whatever you set it to) and still almost nothing idle, literally almost 0 V idle just like adaptive. You just have to make sure C7 states are enabled.
1.27 V peaks are nothing to worry about, but as I get closer to the thermal/voltage limit, I just get uneasy about those spikes.

Cool, thanks.

Yea, I made sure to test out anything I'd do during usage (gaming, net, lite video encoding), and it seemed to stay within very acceptable levels (what I mentioned). Of course, this isn't at the chip / mobo breaking point.

I'll try more later, but, I think I'm going to stay with my current settings, since it's running so damned good. I won't use adaptive at increased voltages though, and am still keeping a close eye on it.

I'm happy with it at 4.2 right now. This CPU is just so bad, even at stock... I told my ol'lady I was going to marry it. biggrin.gif

Well I am new to Intel over clocking...not over clocking in general. 85* is hot for 24/7 use but it was for stress testing and still within the CPU's thermal limits. There are many reasons why I want 4.4+ GHz....first one being this is "OverClock".net and the other reasons are rendering/editing vids and photos and playing games. Some of the games I play benefit from higher core clocks rather than multiple threads. In addition this system can only run one graphics card so I would like the best performance out of the system as I can squeeze.

Well I got 4.3GHz at a lower Voltage by lowering the ring bus to 3.8. 4.3@1.27 Volts So far over 8 hours in Adia64 and temps look like they only touched 80* twice. with the max temp being 80* on core one. seems to be hovering around 68-72* during testing. Anything over 4.3 still wanted ~ 1.35 Volts or more.

I had my 4770k at 4.7/4.6 uncore with these results but I had this going for about a month then backed it down to 4.4 along with other settings.

1.45 Vcore
1.50+ Ring Bus Voltage (I don't remember)
1.95 Input Voltage

Don't ask about the temps lol. Obviously I showed no mercy for my poor chip and I payed the price.
