Are temperatures and power consumption indicative that higher voltage is being used or is it just a sensor or app glitch?

yes 3 cores with higher vcore runs 10C hotter. I can't see powerconsumption per core but for the cpu package its 115W with 4690k it was only 98W

it could also be higher current not necessarily voltage that would increase the amount of power it is eating up.

Ohms law is VxI=P

1v x 10a = 10watts
1v x 25a = 25watts

same voltage different power, more heat.

Dunno why Intel would replace a perfectly good CPU that is within specs otherwise it would not leave the factory.

Always OC core first, then the rest, you're trying to do it all at once and then surprised that this that isn't stable and hard to track down why. Do one thing at a time, not all at once.

Core only first is exactly what I did. The problem is my cache is overvolted in stock configuration and throws everything off.

I tried core only while locking cache at stock. Then cache at 30x with intel programmed VID. 30x 1.15v. 37x programmed VID. 37x stock VID. 40x through 43x auto volts.

The reason I've been going for both at once this time is I've noticed my core is most stable with cache within 3 bins of core. The reason I've been having so much trouble is I've never run into any example of someone able to run their cache at +4 bins at +.03 volts, and none of my cache-centric P95 testing pointed to that being a possibility.

I'm not trying to argue on a technicality basis that its faulty. I'm just wondering if anyone thinks I could find an Intel customer support type who might be sympathetic to my sob story about a chip that needed cache voltage 200mv higher than average to barely skate under max stock core VID.

edit: All of that said though, I was just worked up last night. I've wasted a LOT of time overclocking my core on what anyone would call an incorrect cache voltage due to misplaced faith in stock settings. Now it's time to find my actual cache voltage at 39x and redo the core OC from there. Maybe I'll get lucky and discover my core scaling is actually decent despite such a high stock VID.

what could possibly cause 3 cores to eat up more current than the last one? doh.gif

Seems like higher voltage then indeed. No idea why, if it's only on this particular CPU try RMAing it or at least asking if it's valid RMA with the above finding that 3/4 cores don't respect set voltage. I bet it may be just using your voltage on 1 core and the rest runs automatic/adaptive/stock VID which does scale up high once you start to raise multiplier.

Mix: you can ask the shop/intel who ever processes the RMA if it's valid, but 4790K has been seen stock voltages up to 1.25V-1.3V or something like that. Sure 4690K lower but it may still be within their specs.

It's always up to the person or robot that ends up processing your RMA. No one here can tell if it will pass or not.

Thanks for advice thumb.gif, i shall contact the seller i still got 6months of warranty left.

My first i5 4690K on UEFI defaults showed reading of ~1.20V in monitored values in UEFI. I was able to take that down to 1.15V and increase cache ratio to 41.

My second i5 4690K on UEFI defaults showed reading of ~1.10V in monitored values in UEFI. That has been ample for cache ratio of 44.

On my Asus board it seems UEFI is programmed to raise cache voltage if left on "Auto" and you increase cache ratio.

Yeah some boards will raise Vring when you increase core ratio, I guess that's what you meant.
Do not leave settings on auto as they will AUTO adjust based on your other settings. While this works for Vsa, ioa, iod, ... even those can be lowered to save power.
post #20810 of 22487
Yep smile.gif , when I said cache voltage = Vring wink.gif .

I'll be honest I haven't set every setting manually, only the ones I required:-

a) for OC
b) to lock them if "Auto" was changing them to something I didn't want.

My Asus M7 Ranger UEFI settings changed from defaults (Click to show)
