CPU Multiplier HELP!

[Matriox]

I just overclocked my i7 4790k to 4.7Ghz@1.256 volts aka i changed the multiplier to 47(47x100) but in cpu-z,whenever i do %100 cpu tests, my multiplier drops to like 45 which changes the overclock to 4.5Ghz..So whats going on here? my temps are amazing sitting around 61-70 degrees and tests show no throttling but is it? if so how do i fix it?

You may need more voltage, or to increase the TDP limits more. Or the current limits. It sounds like you're running into a power bottleneck somewhere, but it's not enough to trigger a BSOD. It's happened to me in the past. Can you run the test and use HWiNFO in sensors only mode and show me your drawn power? Also, remember that each CPU test draws different amounts of power. XTU stress tests only takes 62W from me at 3.8GHz but Linpack takes 93W at the same settings.

At the moment my tdp Max's 93w at now 1.288v

can you post a screen shot while the cpu is under load?

 

make sure to right click on cpuz to show what all cores are boosting to.

 

are you using intel xtu at all?

I guarantee you that 93W ain't enough. I suggest setting that limit to about 150W and current limit to about 120A. See if that works.

Where do I change the tdp limit on the z97 mpower max motherboard?

what's xtu?

[ProKoN]

what's xtu?

intel extreme tuining utility

. it works well with msi boards.

 

would you like a couple links to my videos?

Yeah you should really install intel XTU. It's a program that allows you to change settings available in your motherboard. I'd suggest using it. I believe the "turbo boost power limit" or something similar should be the correct name if in the BIOS.

you dont have to touch this setting at all on this platform.

If his CPU is throttling and only drawing 93W at maximum load with such a heavy OC, he might have to raise the setting.

okay I used that program and so far nothing new..I changed the tdp max to 150 and it still stays at 90ish

these are the values in question (yellow indication) the default settings on all boards provide more than enough power headroom for normal overclocks. less than 6 ghz kinda thing. you can slide all four sliders to the right and hit apply. prolly wont make any difference.

Show us your settings?

run the cpu stress ( left side tab in xtu) test and monitor core frequency in xtu

 

does it drop to 45 or is it at 47?

[D2ultima]

his core voltage is set to default... why not try raising it a bit?

[ProKoN]

lol by default its prolly pumping 1.28-1.35V to the chip with his 15mv offset

 

ask for a voltage before you suggest increasing it.

Solved it without xtu..I went further in my bios and had to disable intel speedstep..After that it shows 4699-4700Mhz and is locked and now im able to get 10.29 in cinebench Thanks for the help though

stable at 1.288v that's fine right?

[ProKoN]

stable at 1.288v that's fine right?

 

4.7ghz @ 1.28V is very good. keep load temps below 85c. good overclock if its stable. post your cinebench scores in the cinebench thread

 

ideally you want to have eist enabled as it is the better long term solution.

 

Enhanced Intel SpeedStep® Technology= downclocking when idle

 

http://www.intel.com/cd/channel/reseller/asmo-na/eng/203838.htm

 

is different than

 

Intel® Turbo Boost Technology 2.0 = maximum core frequency

I lowered the voltages and for 20 minutes i'm able to keep a overclock of 4.7Ghz at %100 usage 1.248v so hopefully that holds up and the max temp so far is 72 degrees

i suggest minimum of 8 hours . run it for an hour and if she holds stable go do some normal tasks benchmarking gaming etc.

 

run the stress test before you go to sleep and hopefully she is still running when you get up.
