I5 4690K multiplier drops while using cinebench, what can i do?

[KURUJEASY]

Dear forummers,

So I started OC my i5 4690K to 4.3Ghz at 1.29V. When testing with cinebench while looking at both CPUz as Core Temp I can see the multiplier dropping from x43 to x35(base core speed out of the box without turbo).

I disabled c1e, c3, eist, thermal thing, turbo etc(the whole list below the turbo - as that is what Ive found in other topics). It keeps occuring. Temps reach a max of 60°(at x35 ofc, since the moment I start cinebench it drops to x35).

While gaming my core speed does seem to stay at x43, its just that when starting cinebench it drops to x35 and that I cannot accept 😛.

I should say that I have not tested other CPU benchmarks, i did re install cinebench itself.

Hardware:
Gigabyte Z87 board;
I5 4690K cooled with seidon 120v;
16GB DDR3 1600mhx G skill;
Corsair 550W;

... and an R9 280x(relevant?)

Where are you guys thinking of? Thanks in advance.

Any ideas?

Sorry, I can't think of anything. Maybe increase CPU Max Current in the BIOS if you have such a setting?

Thank you for your answer scuzzy, I will try that in a moment. In the mean time I also used Prime95 - and again. Multiplier goes from x43 to x35 within a second. I ll reply to you once I've done it. Breakfast first 😉

Couldnt find it. I could however find it in intel XTU. Tried increasing, still lowers the multiplier.

Which Gigabye Z87 board do you have? The basic model only has 4 power phases. There's a possibly that it's throttling because it can't handle the current demand. As an experiment, try 4.0@1.12V and 4.1@1.18V. Does it still throttle with a less-demanding OC?

I have the GA-Z87-HD3 Version of the mobo. I am not at home at the moment, nor will I be until next friday. I cant really detect how many power phases it has.

I cant report back on the smaller OC at this moment.

That one is a 4-phase design, unfortunately. Is this a gaming system? Most games do not cause the CPU to draw nearly as much current as synthetic tests, so it's very likely that you're still getting full-speed during game play. Let us know how things turn out.

Hey Scuzzy, that is what I said in the OP. During games it seems to be totally fine and running at max frequency. It is a gaming system yes. So does that mean I can still profit from the benefits of overclocking in games - or, when I game at max settings when the game is requiring a chunk of the CPU, the multiplier will still drop? I guess I ll have to find out myself for that as you can probably not answer that.

I appreciate your insights. They have been helpful. Is there any board that goes for sub 150 euro retail that does support... more power phases 😛?

Also, where did you see the 4 phase design, how is it mentioned in their specifications(future knowledge for myself - as I couldn't find it there)

Thank you,

I can tell by seeing the 4 mosfets next to the CPU socket, but you can google "GA-Z87-HD3 4-phase" as I did to make sure I wasn't missing something - looks CAN sometimes be deceiving.

Gigabyte's own Gigabyte GA-Z97X-GAMING 3 is an 8-phase, and is $119 https://www.amazon.com/Gigabyte-GA-Z97X-GAMING-Gaming-Networking-Motherboard/dp/B00K2RQDXY

It's actually a relief that your motherboard automatically throttles when the current demand is exceeded. Many, many boards will just stupidly burn themselves out, and/or spontaneously reboot when their current-handling capability is exceeded.

I would still test it out using monitoring and logging software such as AIDA64. If it doesn't throttle during your games, I wouldn't worry about it too much. Your current setup is more than capable, so it doesn't make much sense to swap boards at this point. I also think that Intel might just release something ground-breaking once AMD releases Zen next year. I'd say don't invest more money into Haswell, skip Skylake, probably skip Kabylake, and then consider Cannonlake or possibly Zen with a more robust motherboard next time

Hi Scuzzy, a bit of a late relpy. I have decreased the voltage to 1,190(as you said with power phases, my logical mind thought about trying a lower voltage to make it easier for the mobo) and I clocked it lower also, 4.2ghz. It now fully functions and sometimes only goes back to x41. I have yet to try a OC of 4,3 and 4,4 with lower voltages - perhaps that should work also.

Thank you for your answers.
