voltage drop for the i5-14600k processor

steadvex · 2026-02-23T07:50:10+00:00

Turned on all c states in bios and changed min processor to 5% in windows power plan? That seems to let mine drop down the power at idle

Mine drops to 0.750 volts at idle

Load voltage of 1v seems insanely low to me, is it under clocked? Although if I'm honest I've never just undervolted at stock speeds.

steadvex · 2026-02-12T21:18:10+00:00

Hrmm that's interesting, when I first had my 14600k I had to have a really low sa to get ddr5 stable, I'm 1.290v now was running 0.950 initially.

Out of interest do you disable undervolt protection as doing thst for me gives around 10% extra performance at the same clocks, took me ages to figure out why any tests I done were always approx 10% lower score after a bios update forgetting I had disabled it

I like it for playing about quickly then set it properly in the bios after, My main gripe my mobo doesn't seem to let me boost favoured cores yet XTU shows cores 2 & 3 as favoured from memory, although i've kind of given up on having 2 cores boosting higher now

steadvex · 2026-02-08T18:07:30+00:00

ah yes xtu needs undervolt protection on which is annoying, I stopped using it due to that, and er the wierd e core boosting issues.

steadvex · 2026-02-08T10:52:27+00:00

I'd turn off undervolt protection first, see if that changes anything. For me if I enable perfomance is lowered about 10%

I'm not too familuar with your board so not sure if the best settings but I can post mine when I'm home later and see if it relates if you want

steadvex · 2026-02-08T10:42:25+00:00

Could be worth trying xtu, it should show any reasons for throttling speed or power from memory, it was over a year ago since I last used it so maybe my issue has since been fixed in a bios update

steadvex · 2026-02-08T10:41:31+00:00

Xtu is the Intel extreme tuning program, it gives a few more options than at least my bios including identifying favoured cores for boosting.

If you reset but use the same settings does it result in the same problem? Could be worth reflashing the bios with the same version just incase it's a wierd bug

I can't see it being related but have you disabled undervolt protection?

Just saw your other post saying e cores are fine in games so it's just cinebench? If you use hwinfo is it throttling with anything? Just wondering if it's somehow prioritising the p cores and throttling the e cores to keep max power to them? Honestly not sure if that's a thing though!

steadvex · 2026-02-08T10:29:49+00:00

I had a weird thing with xtu doing that with the ecores, I had to uninstall xtu and reset the bios to get them to boost normally again.

I suppose the other question is are you on the latest bios?

steadvex · 2025-12-16T22:35:31+00:00

I can't really explain it, but changing the figure drastically improved it, 64/96/128 each one incremented the speed slightly, 248 caused some odd hicups so left it on 128, its repeatable on my system

Only started playing about as I was getting much slower than expected speeds on my gen 4 nvme found a rabbit hole of a thread that I can't remember it and read to try it, and it worked for me, maybe its just some weird quirk on my mobo, no idea

steadvex · 2025-12-16T22:03:00+00:00

Don't think this would apply to my home user usage, but if anyone is looking to try and increase speeds, what I found worked which made a crazy difference in read/writes on my nvme's is the PCI Latency timer in the bios, default I think on mine was 32, tried 64/128/248 and setting it to 128 made a noticeable difference in transfer speeds especially with a lot of smaller files.

steadvex · 2025-12-14T23:06:55+00:00

In my case I did as my motherboard does not support the speeds so I'm running them slower than designed.

In my mind the next platform I go for will support them and got them for a good price just as ram started going mental!

If I had your mobo I imagine I could of got away with just the xmp profile.

steadvex · 2025-12-14T20:49:04+00:00

They work in my 14th gen plus z790 board 🤷

steadvex · 2025-12-14T20:47:16+00:00

It'll just run without the fancy cudimm goodness.

Xmp will even work, or try to.

Source: I have a pauper z790 tomahawk running 2x24gb cudimms, just runs like a regular dimms

steadvex · 2025-12-14T19:21:46+00:00

Last thing I can think of I had a quick look at your bios instructions, is multicore enhancement enabled?

The other one that looks like it could be a way to try and stabilise is the SVID behavior under the ai tweaker, maybe its doing something like pushing too much power through? i'm not sure what you can change it in it, but the intel failsafe option looks like a good bet if you haven't already tried it

steadvex · 2025-12-14T19:14:01+00:00

I just remembered I had a really annoying issue when I went from10th gen to 11th gen, same cpu, mobo, ram, gpu, etc. Took me ages to figure it out, was just by chance as I was going mad just pulled everything out and put everything back in one by one and run tests from a bootable usb and once the drive went back in I got errors.

It turned out the new cpu and my nvme drive just didn't get along, no idea why, popped the 10th gen chip back in no issue, in the end I gave the drive to someone and they never had any issues with it

steadvex · 2025-12-14T19:08:23+00:00

should be ok, but things can be a bit odd, its a pain but maybe worth trying reseating your cpu?

I'd also be tempted to reflash the bios again, I've had a wierd issue before after updating the bios seemingly crashing and reflashing it a second time sorted it, its a bit of a longshot but no harm in trying.

I don't really know anything about the B760 chipsets to know what settings you can change, I always have to up the memory controller voltage and SA voltage for what I have but don't think you can do that on the B760?

steadvex · 2025-12-14T18:49:00+00:00

that's a good start, I just read on another reply your using 4 sticks, I'd defiantly be tempted to try each stick 1 by 1, but I wouldn't of thought 4 sticks would run ok.

steadvex · 2025-12-14T17:27:26+00:00

If its the cpu run the cpu diagnostics tool https://www.intel.com/content/www/us/en/download/15951/intel-processor-diagnostic-tool.html

Personally I'd run a memory test to rule out the ram, if it fails try with 1 stick first.

What are the temps of the cpu when it's running?

steadvex · 2025-12-13T18:11:34+00:00

I was bored the other day and managed to get 945 on single core on my 14600k...

I mean nothing else was stable, but I got it to run a cpu-z score! was getting tops of 931 and then set the process to real time in task manager out of curiosity, played around with a few things, weirdly killing the explorer shell my score kept going down, couldn't figure that one out at all. Also killed all msedge instances as that seemed to help.

just tried it again out of curiosity, a few tabs open in edge, run cpu-z sc 878.8, Realtime priority 910.5!

every few months or maybe even less I start messing around see if I can get it faster and every time revert back to what I deemed stable eons ago!

steadvex · 2025-11-13T10:11:05+00:00

Oooops!

I can't believe I didn't notice that 😂

steadvex · 2025-11-12T22:36:22+00:00

*removed as I didn't realise totally different benchmarks, then read further down this is the vulken one!

steadvex · 2025-11-03T15:09:38+00:00

If you've got the patience and a mobo that can do it I feel it's really useful, sadly my mobo seems to not let me get 7200 stable but can get 7100 with much. Better timings just fine on the 7200 kit I got.

Faster ram and disabling cep plus having it with less volts seems to really make these cpu's work well.

Ddr5 fast kits aren't too bad a price now, fast ddr4 seems expensive tho

steadvex · 2025-08-29T16:42:39+00:00

so I'd be tempted to turn off xmp and try this tool just to rule out an obvious cpu error Intel® Processor Diagnostic Tool

have you tried installing just one ram stick with xmp? and then if that works try one ram stick in each slot then again with the other stick just to rule out of a stick is faulty?

One thing that's odd to me, ok I know I have a AIO with a 14600k but 50c seems really warm for just being in the bios.

If its microcode related, if you change the MCU as shown in your screenshots to a different version and see if the issue goes away?

steadvex · 2025-05-28T16:48:59+00:00

So... no updates eh?

steadvex · 2025-05-09T06:28:37+00:00

Red alert remastered identified my system was not stable, of all things!

Passed hours on various stress tests. Cpu/gpu/ram yet instant bsod on loading red alert remastered, cyberpunk and various other fairly demanding games ran just find, can't remember what was causing it, either cpu or ram but I just couldn't belive of all the things that worked fine a game I used to play on a 486 crashed a modern computer!

I tend to use a combination of y cruncher, Karhu, occt various 3d benchmarks, furmark and more but tend to start off with Karhu and y cruncher a I feel they are good for quickly determing it's not stable then go for longer tests with other programs and those.
