hello!

I was hoping someone may be able to help me. I am trying to overclock my i5, but every time I run a stress test, it downclocks to 4.5 ( I think this is its turbo boost?)

When I stress test without the OC, it happily clocks up and stays at 4.5. Any kind of tinkering at all with an overclock and the problem starts. CPU-z will show the overclock either 4.7/4.8/4.9 ( whatever I clock too) but after 20 sec of any stress test ( I have tried a few ), it downclocks.

I have looked through lots of guides and have tried to troubleshoot myself..

Temps are all fine.

I am using an Asrock 490 Phantom Gaming 4.

Any help would be great! thanks

It's probably thermal throttling. Run hwinfo and monitor temps especially the specifically the VRM mos, should also tell you in there if it is thermal throttling.
 
Hi!,
Thanks for the reply.

I run hwinfo,, I can not find VRM mos, but under auxiliary, there is Auxtin1 ( this could be it? ) it reads as 107 degrees!
Auxtin 2/3/4/ are 22 - 28 degress.
its also showing the maximum vcore volts as 2.4v, with the minimum at 1.36v.

When I run the Stress test, the temp does not increase or decrease on any of them.

I dropped the current-voltage down to 1.25, and the OC to 4.6,, after 20 secs its just downclocking again.

Any idea where to go from here?

Again, thanks so much for the help

Try positioning a fan over the Vrm heatsync to blow cool air down on it and see if this makes a difference.

I'm guessing the downclocking only happens at heavy loads and stuff like gaming so runs fine?
 
hi!

I dont have an extra fan to point at it.

My heatsink is a noctua nh-d15.

I have not monitored anything while gaming.

I just run intel burn test on standard, and the core speed looks like it stays higher.

Whats the best thing to do?

Should I see how far I can lower the core voltage?

Also is there an option to remove VRM throttling? I have just been reading about increasing the Max CPU current limit. Also Does the max TDP limit things, CPUz reads as 125.0 W

I went back into bios and reset. I left everything on auto and set an OC of 4.7, it still throttles back

Cheers!

http://www.imagebam.com/image/144f6a1360674755 I have been running HWinfo with the overclock and stress test, can see that Its saying 'max VR voltage' = yes

Any ideas what this means and if this is the culprit ?

Thanks

no way should your processor be using 1.352 volts @ 3.1 GHz.

set voltage to manual and avx to zero enable multi core enhancement max out your power limits.

might try to stick some 40mm 50mm fans to those VRM heat sinks they are shockingly small.
