I5-2500k - Extreme 6 p67 Overclocking problem

[Slufa111]

OK heres the deal.

Intel Core i5-2500K Sandy Bridge 3.3GHz
ASRock P67 Extreme6 LGA 1155 Intel Motherboard
CORSAIR H80 (CWCH80) High Performance Liquid CPU Cooler
G.SKILL Ripjaws X Series 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600
Zotac Geforce GTX 460 OCed SLI
64GB Kingston SSD (boot / most used apps)
500gb Barracuda 7200rpm Storage drive
ASUS 24X DVD Burner
XFX XXX Edition 650W PSU

I overclocked to 4.7ghz @ 1.375V. I disabled all the power features I could see in BIOS and when I boot up to windows I load CPU-Z, it says 4.7ghz. When I prime95 it underclocks to 4.0ghz.

I have tried everything..can someone help me?

Increase the "Turbo Boost Power Limit" and "Core Current Limit" in UEFI setup.

Someone else with experience with ASRock boards may be able to tell you what values are good. On my Gigabyte, I set both similarly named parameters to 300.

Like MT said.
Your CPU is throttling back when you put a load on it. Your UEFI bios should be similar or identical to mine. Set Turbo Boost Power Limit to Manual and set Short and Long Duration Power Limit to 200-300. Start at 200. Set Duration Maintained at 1.

Something interesting I found on my Extreme 4 is that when you turn SpeedStep off the Power Limit options disappear. I found that if I set the power limit first then turn SpeedStep off the setting still held even though they weren't visible.

 

[Slufa111]

I upped a few voltages and re-flashed the bios, adjusted the power limits and turned my stepspeed off. (not in that order lol) and I am 4.8ghz 1.435v.

I like only messing with the Multiplier and not messing with the base clock like I did with AMD

That happened once to me when I ran linx at 50x and it throttled back to 46 for half test at 80c.
It was the first and last time I hit 80c and the last time I used 50x.
Turn turbo back on and lower vcore or llc to 3.
Get better water cooling such as good wb and a 120x3 radiator.
I can handle 48x using c2d wb but not much more.
Try adding two 120 100 cfm fans to the rad may help.

1.435v. will run too hot in prime get it down to 138 -1.41 tops.

 

[Slufa111]

I only get up to 77C. I have aftermarket cooling. As far as I know this chip has a very high max

 

[tweakboy]

I know your itching, go to 5Ghz ... You can if you have massive air cooling or your under water. If I got my hands on ASUS .. always. and a mandy moore bridge . Ill OC the black edition to 5.5Ghz easy. By the time its 2018 and we have 10nm then you can pown your old 5.5Ghz ,,,

hehe :whiste:

 

[Slufa111]

I want it but I know its better to play it smart. Ill stick with 4.8ghz.

 

[Diogenes2]

( Waiting for OC police to warn of danger of higher than 1.35 vcore....:whiste: )

 

[john3850]

Excellent post diogenes2

BEWARE of your OC
The OC patrol gang has been very active.

 

[Slufa111]

Why? I am running very exceptable temps @ 1.42V

Some research has shown that a lot of ppl run above 1.4V

 

[Slufa111]

Fine. 4.7ghz @ 1.370V!

I hope your happy

What do you think about that? 16GB of ram overclocked 133mhz. I like!

You mean 233MHz OC on the RAM, right?


And you beat my first try OC of my 2500k......a piddling 4.4GHz on 1.104V. Guess I should try a little more voltage and higher multiplier.

 

[Slufa111]

DDR 3 - 1600 = Each module is running 800mhz

DDR 3 - 1866 = Each module is running 933mhz

The difference is 133mhz

Why?

It makes negligible difference in performance with P67...

Just out of curiosity, why would you turn speedstep off? I usually don't feel like its worth running full speed when i'm idling in windows or watching a movie or downloading something. With speed step it will automatically go into turbo mode when you're doing a game/encoding etc but for nominal tasks it doesn't. It doesn't affect how far you can OC.

edit: nevermind, I should really read all of the posts in a thread before responding

Agreed, I feel its not really worth going out of your way to OC ram. I think there's an article floating around somewhere showing the difference between ddr3-1600 and ddr3-2133 is maybe 1 fps in games, if that. I'd rather squeeze more MHZ out of the CPU or GPU, there's way more of an objective performance increase.

Only 77? Seems a bit high for your cooling setup....., what are your ambient temps like (just curious)

 

[Slufa111]

I am sorry, I not using the H80 yet, I am using my Hyper 1212+ until my H80 comes in.

Temps should go down.

Should have clarified that!


I am just not happy with the Extreme6 P67. SATA connectors are weird, the BIOS is flaky, and the features are scattered.

I returned it for a ASUS P8Z68-V PRO LGA 1155 Intel Z68. I will be running ASUS P8Z68-V PRO, I5-2500K, and a H80. I will see how it works out for me on Tuesday!

 

[blackened23]

I think you'll like the Asus board, thats the one i'm using too. If you have an SSD drive be sure to put it on the marvell controller and not the board controller, though.

So you're from ft. bragg? Is it a hellhole like camp lejeune is? I flew back from my last afghan deployment and a bunch of field arty cats from ft. sill. Aside from the whole army/marines rivalry they were pretty cool people. I never saw chicks carry saws before then, though, that was a surprise.

 

[Slufa111]

Hopefully I like it because I ain't doing this motherboard swappin forever lol.

I was at FT. Stewart before I was here (FT. Bragg) and I gotta say, I like Stewart a lot more. I have gotten a lot more fit since being here but when you run 15 miles a week getting fit just goes with it.

They wear the same uniform, I have seen some carry 240B. Now thats hardcore. lol
