High CPU Core Voltage (stock settings)

am I right in thinking that before the bios update when it was pulling 1.4v and was set to auto, the voltage would have varied depending on load? if so, it'd mean it wouldn't have been pulling 1.4v 24/7
 
still getting blue screens (but it's always with VIDEO_SCHEDULER_INTERNAL_ERROR). i've uninstalled my graphics card drivers and reinstalled them (after i'd reinstalled Windows i crashed shortly after installing video drivers so I'm hoping that reinstalling them will fix that particular issue)

will run a stress test now and see how that goes.

regarding the memory - the timings are different to what's specified on the ram?

their web site: DDR3 2133: CL10-12-12-31
my ram: CL11-11-11-31
 
ok ran a very short stress test, i don't want to run it long at all with cores reaching 80°C. i've ordered some thermal paste and will clean up and remount the cpu once it arrives, hopefully it'll make a difference and i'll be able to test properly without hitting such high temps.

i've been in touch with ocuk but they haven't been very helpful. i'd asked about the core voltage (before i posted here), they replied this morning just pointing me towards intel stating they have a 3 year warranty. i replied and said it was sold as a bundle (intel were asking for info from the box), they replied saying that all the information i need to do an rma with intel will be available on the chip itself. i'm going off topic a bit here but i don't think i'll be ordering with ocuk again, every bundle i've had has had issues. the first bundle i bought from ocuk back in 2011 (i think) was a phenom oc'd to 3.8ghz, pre built. it was unstable after 10 minutes of getting it going. they suggested a number of different settings (none of which i was comfortable doing), but nothing worked. ended up removing the oc entirely, which to be fair was completely stable afterwards. in hindsight i should have sent it back immediately but i had that for around 3 years before it really started to struggle with games.

i've spoken to intel and they've asked me to do some diagnostics using their own software, and said they would honour the 3 year warranty if there were no signs of physical damage. i'm worried there will be (with it pulling 1.42v and reaching high temperatures for the past couple of years). the strange thing is that i've never had an issue with the machine, it was rock solid stable and had never crashed. it was only because i happened to install hwmonitor and noticed the high temperatures that i ended up on this path and luckily noticed the high stock voltage.

the most annoying part about the whole thing is that i intentionally bought a pre built bundle because i don't know anything about overclocking or compatibility (ram etc.), so i thought i'd be safe. i'd have thought they'd have checked and noticed that the motherboard was supplying such a dangerously high voltage to the cpu :( on the plus side i've learnt a little bit due to the support i've been getting.

i've tried increasing the vcore, but that was when xmp was enabled (which appears to be a lot less stable than with it disabled)

i'll load up bf1 and see how that goes. haven't tried any games since reinstalling windows yesterday. i've just been doing short stress tests with aida (i presume bf won't get the cores as hot as that does anyway - probably a good way to test stability?)

i haven't posted anything in there, but i may as well. i'm clutching at straws here.

is there any chance the motherboard may have been damaged as well (due to the high voltage)?

i'd ordered a new asus rog strix 1070 graphics card at the same time i got the case but that didn't arrive until today. it's just sat in the box. no way i'd want to put that in if there's a chance it could get damaged (i wouldn't put it in any way unless i could completely resolve the instability issues)
 
just downloading bf1 atm. I haven't had any crashes since reinstalling the gfx card drivers so hopefully that's sorted. will give it a good test on bf and see what happens. thanks for all of your help so far
 
ok so i've got bf up and running, left it on in window mode so i can monitor temps, here's how it looks after 10 mins:

i'll leave it running, the temps are much better here. will give it an hour or so and see what happens.

no crashes still so far
 
ok so i just left bf1 running for an hour, in that time i played for around 15 minutes without issue.

quit and decided to run aida, i intended to leave it running for 15 minutes. after 4 seconds it froze, blue screened with CLOCK_WATCHDOG_TIMEOUT :(

everything i've read regarding this error points to the cpu. given i'm running auto voltage i'm starting to think that the cpu is damaged as a result of the voltage it was receiving from the motherboard under the old bios. i don't know if i'm right in saying this, but it seems my only option at this to set the voltage manually, and increase it. the problem i have with this is that temperatures are already quite high (hitting 80°C in aida in under a minute) and any additional voltage is just gonna burn it up more.

just a quick update - i took your advice and posted in the customer services forum with a bit of background information and linking to this thread. Ohlawll has obviously had a look in to it and has very kindly told me he would like to replace the cpu for me - i can't believe it! going to remove it tonight, package it up and send it off. will have a couple of days downtime but i'll be more than happy if by the end of it i have a working pc (with normal voltage/temperature!!).

how should i safely package the cpu? i've never had the box. i do have an antistatic bag from my gpu, but im concerned without inserting the pins in to some foam or something they might bend. there is a lot of foam in my gpus packaging (see below), but is it safe to insert the cpu pins in to it or do i risk damaging it? (sorry for the dumb question)

thank you so much for all of your help, i've learned so much

harney - was it not the motherboard bios causing the problem? when i first noticed the voltage on friday/saturday and reset with defaults (xmp disabled), the voltage was still at 1.419v. i'm hoping that's the cause (after updating from F4 -> F8 the voltage dropped to 1.224v) because if i enable xmp again with a new cpu and it spikes up i'm back to square one (would definitely have to replace the motherboard), though i'm hoping it was just the bios (i'd read, and i'm sure someone else mentioned in this thread, that this was the problem)

ah shows how much i know doesn't it :|

i'll just pop it in the bag then and bubble wrap it

so when the new cpu comes. put it in, put some thermal paste on (ordered some arctic silver 5 - reviews said it was good?), put the cooler back on and fire it up. then just enable xmp and see if it's stable?

thanks again for the help, appreciate it so much!

hi guys

i'm very happy to say that i'm back up and running. ocuk received my return yesterday, and within 20 minutes of doing so Ohlawll had personally gone and picked the replacement, and upgraded it to saturday delivery free of charge. incredible customer service!

i'm running with optimised defaults again, all i've done is enabled xmp (so far so good, ran a short 15 minute stress test in aida, max temps reached 59°C without the fans hitting 100%). vcore is currently sat at ~0.72v with cores idle, but with the boost clock it hits 1.283v - is there any reason to be concerned or is this perfectly safe?

just wanted to say a massive thanks to everyone, but in particular harney and new boy, for all of your help in getting this issue resolved. you've no idea how grateful i am, and i feel like i've learned a lot! big thanks to Ohlawll as well for sorting me out with a replacement so quickly, given the circumstances i don't think i know of any company who'd do the same.

fingers crossed there are no more issues!
 
yeah i thought it was a little on the high side (and i like to nitpick as well) so i had a read through the oc guide somebody posted earlier in this thread (which uses the same motherboard as mine).

i set the cpu vcore to 1.16v as a test and worked my way up until it's (hopefully) stable. ended up at 1.190v. i've enabled C3 and EIST so that when idle the frequency and vcore voltages drop (~0.76v). one thing i did notice is that the VID for each core is slightly different (and none are exactly what i set the vcore to(?) - see img below)

A4MEC7c.png

and further down in hwinfo, there's some entries from the motherboard with their own vcore readings (i presume these are accurate since the ones in the image shown above don't show any fluctuation in voltage whereas these do), but they show vcore at 1.140 in the top part, and all cores hitting 1.134 in the second:

OqVXVJj.png

either way the voltage is still much lower than it was, and temperatures are down even further!

so, just out of interest:

1. what's the difference between vcore and vid, and why do i see a difference between the maximum reported voltages for the vcores in the sensor data from hwinfo?
2. why does vid show (in the first image) show ~1.120v on all cores when idle, but the second image shows vcores around ~0.76v?
3. when vcore is set to auto in the bios, what determines the voltage the cpu requires?

ah i had it set as a fixed voltage in the bios. there is an option for vcore offset but you have to set the vcore voltage and then separately the set the offset, and i have no idea how that works :| is it just a case of setting the vcore to say 1.25v and then setting the offset to -0.5v?

anyway it turns out it wasn't stable, ended up blue screening again (same error every time it has happened since i tried lowering the voltage - WHEA_UNCORRECTABLE_ERROR). i've read that it's related to undervolting the cpu so i'm not too concerned (had vcore @ 1.190). for the time being i've set it back to auto (vcore maxed at 1.297v on all cores, vid ~1.280v) which seems high and temperatures have increased a fair bit (hit 76°C playing bf1 and i can hear the fans mounted on the rad spinning up now).

will do - i'm determined to get there in the end :)

i have another question (sorry, i promise i'll stop eventually :p)

i've noticed that all cores boost to 4.4ghz. from what i understand this shouldn't happen. i checked in the bios and under intel's turbo boost technology there's a clock ratio which shows that if:

1 core is active: x44
2 cores are active: x44
3 cores are active: x43
4 cores are active: x42

yet if i go in to the MIT status in the bios it shows all cores boosting to 4.4ghz. i can't find anything in the bios which may be affecting this but it doesn't appear to be paying any attention to the ones set :| i'm wondering if this is possibly what's causing the cpu voltage to be set so high. any ideas?
 
yeah - it's starting to become a bit of an obsession now lol. i'm pretty certain that boosting all 4 cores to 4.4ghz is the main culprit for the high voltage.

i found an interesting article here which is what i was describing.

as a test i disabled intel boost technology in the bios, the voltage plummeted (1.09v) and temps are now under 20°C idle, and under 50°C at load. i also tried disabling xmp (it's been suggested that that can cause all cores to boost), but that had no effect whatsoever.

so it's essentially forcing an overclock on my processor which i don't want, and i'm pretty sure there's no way i can turn it off :|
