High CPU Core Voltage (stock settings)

another strange thing i've noticed. my corsair h75 has the two radiator mounted fans connected with the y-cable supplied by corsair to the cpu_fan header. the pump is connected to SYS_FAN6 as it sits next to the cpu, however, it doesn't appear in the bios? the bios only shows system fans 1, 2, 3 and 4. i have two 140mm case fans connected to 3 & 4 which show up with their fan speeds normally. 5 and 6 don't appear in there at all.

also, if i manually set my cpu's voltage, it'll stay at that voltage (according to hwinfo and hwmon), whereas if i set it to auto it'll fluctuate based on load (~0.725v idle, 1.236/7v under a stress test). it hit 1.236v on 3 cores, and 1.237v on 1 core after a 2 minute stress test) - no crash (xmp disabled)


So OS off the list

Them errors are strange

ok so if its stable and not in the 1.4v territory leave it on vcore auto then do more testing if it stays stable and temps are good looks like where finally getting somewhere

then do not use xmp as this seems to be the issue but manually set your memory to the correct timings which are CL-tRCD-tRP-tRAS 11-11-11-31 and 1066mhz in bios (this will work out @ 2133) and see if mem voltage can be set to auto...rinse repeat tests see what you get

its looking to be the mem at fault here should be fine with the correct manual settings

i've had core voltage on auto with xmp disabled previously, it seems more stable but does always crash eventually. how long should i be stress testing for?

temps are getting quite high still (high 70s) when the cores are pulling 1.236v. I'll get some decent thermal paste and remount the cooler head, perhaps the pre applied stuff is no good or maybe it's not mounted correctly? it's fine idle (all cores low 20s with the fans running quietly, under a stress test they spin up and the temperature spikes to high 70s)

seems fine to me yes when you get some good paste re do it no harm

you want aida to be stable period you do not want it to crash if not stable then there is still an on going issue

if it does crash increase the vcore a little above what your seeing now while benchmarking in aida say1.25 + we can mess with the offset but this set to auto should do what it does and save messing about with other settings...

still do not understand why stock does not work so its either its hardware fault since u had it from new or could be the fact u have been pushing cpu 1.4v since new not sure...
 
ok tried setting the memory timings manually, computer powers off during post. there were additional timing settings which i just left on auto, i only set the CAS Latency-tRCD-tRP-tRAS 11-11-11-31. DRAM voltage on auto appeared to stay at 1.5v, i couldn't see what it set it to after saving and rebooting because it reset the bios stating a configuration fault after switching on after it powered itself off. Tried the memory timings and manually setting the voltage to 1.65 - same thing, switches off during post.

I've loaded optimised defaults again - auto voltage, xmp disabled

:(

try the memory in the other two slots and try the same timings again ...
also while you do that
i know the info is in the link you gave me re mem but can you give me the make and modal of them just to be 100% sure there the same in the link
 
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

possibly if you had power features on ie balanced or power saving in the power options

so browsing ect yes
gaming no or high loads
 
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.

Good spotting not sure what's going with that i am sure its the right one ....

What i want t do 1st is get the ram cpu stable then deal with the gfx

Which slot is your gfx in ..also it might be worth installing an older driver from nvidia and test form there ...as we seem to be battling a few things here

Also in Aida make sure you do not select drives or gfx the only one's ticked should be the 1st four cpu fpu cache and memory (which you are seen the post )

Ok yes will halt for now until you get some paste and resume once you do

will keep an eye on this post ...
 
80c is fine for stress testing 85c+ is where I would not want to leave it for hours and hours on end.

Did we try just increasing vcore and seeing if that makes it stable at stock settings?

If you try that, and it is stable, then I would be asking OCUK for a RMA as it was sold as a bundle so OCUK should really help out with that if its still in warranty which I think you said it was.

Agree with you OC uk should not have sold him this as running in xmp at 2133 1.65 was pushing 1.4 volts to the core since he has had it over 2 years not good really is it ...

So yes agree it should be taken up with OC uk
 
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 feel for you Billyonecan its not good really as you state to buy a bundle less hassle ect as you did not want to deal with a full setup and not to run into some thing like this .....

i have delt with a load of z87 z97 builds from other builder's with the same issues with XMP and certain MB / memory combos...

Some MB and memory are fine with xmp but others well as you know with yours does not work as intended ....

Re intel maybe you could rma it and get another.. bth you may just end up back with yours once they test its fine or another refurb chip...but you could end up with a sealed one you could even demand a sealed one worth a try at least ....problem is down time not having a cpu....

in an ideal world would be great if you had some other memory to test ...

Will wait till you get your paste and take it from there ...
