4670k not taking IXTU voltage

[Bubbleawsome]

OP IS NO LONGER RELEVANT
Look down. Around post #9 and #13.

Spoiler

In short, Intel extreme tuning says that stock for my 4670k is 95amps but proposes 256amps. :O

Kinda worrying.

 

[crashtech]

It's removing it from consideration, essentially. If there is a power limit still in place, 90W in your case, then the current limitation is a bit redundant, imo.

 

[Bubbleawsome]

Ok. 256 then.

 

[Blitzvogel]

Power / Voltage = Amps

Amps is total max amps going straight into processor and not Vcore right? 256 seems a bit high but I honestly have no idea what kind of voltage Intel processors need.

 

[crashtech]

Well, at 1.28V the current is going to be 70A with a power limit of 90W. I think in a way, the power number tells you more about what you are allowing the CPU to do, since it correlates better with the TDP number than anything else. If you know about the heat dissipation capabilities of your cooling system, you can adjust the power limit accordingly.

I have Turbo disabled on my CPU, preferring to run all cores at max when they are called upon, using temp data to adjust clock and voltage to acceptable levels.

Without any voltage tweaks under max load (AVX) I am running all 4 cores at 4Ghz at 1.13v. Wattage ends up around 75 and temps are in the low 60s. It looks like I can push it a lot farther.

Pretty much. Heat is the enemy of all electronics as my basic electricity teacher this semester would always say lol. I have no idea what my Phenom II x4 925 can take.

 

[Bubbleawsome]

Not quite related, but can someone tell me what all this means? I remember some stuff about D0 chips clocking better, but not that much.

Says E4 in the circle by the way.

 

[Bubbleawsome]

Oh, wow. I just reinstalled everything and now at 4.0 and linX I am shooting to 100w and 71c and then it power limits back down to 3.4. D: I don't know what the motherboard is capable of (120w?) so I don't want to push much farther. Is this normal?

EDIT: Wow. Gave it full power for a quick run at 130w (Mobo spec) and this happened.

EDIT2: This is it at stock. Turns out AVX wasn't on before as I was getting ~55Gflops then.

Well. Should I set an overclock for normal usage and allow it to power throttle in AVX?

EDIT3: *$&#% HDD started clicking and windows froze. I have no money to replace the dang thing. I do have a full USB backup though from today, so that's nice. Dang everything.

 

[crashtech]

Synthetic loads with AVX2 will heat up the CPU beyond anything most people will do in real life. So it's your call. I do think that if you are increasing the power limit without increasing the Turbo bins, you aren't going to get anything but more heat. You might want to try disabling Turbo, at least temporarily, and adjust the multiplier and core voltage until you find settings that work well for you. There are a lot of good overclocking threads in this subforum by people that know a lot more about it than me. You should check them out. One thing I do know is that my 4770K has been the pickiest CPU ever about overclocking.

 

[Bubbleawsome]

I think I will see if I can tell it to activate different clocks when AVX/AVX2 is in use. If I can't I will tell it to limit to ~90w. Temps seem really high for 1.09v though. I don't see why less than 1.1v is still drawing over 120w. :|

There may be something wrong with voltage reporting. My motherboard kept wanting to put 1.39V into the CPU core when left on its own to decide, which is insanely too much for air cooling, imo.

That's insane. I hope it wasn't doing that. I don't like going over/near 1.3v. D: I will report back once I boot back up. *sigh

 

[Bubbleawsome]

I'm back! Does anyone know how to use voltage control in IXTU? I tried to tell it to use 1.00v but it decided it liked it's stock 1.14v anyways. I actually want to raise it a bit (~1.2) to see what is causing some instability I am having. My motherboard (MSI Z87-G41) doesn't seem to have many controls at all.

 

[crashtech]

I'm not familiar with the MSI UEFI (BIOS) at all, but I would suggest you take more time to familiarize yourself with it rather than using the Intel software. There are probably some controls in there that will allow you to revert to manual control of many functions. The Z87-G41 appears to be a lower-end board, but if you are lucky it may share some UEFI functionality with it's bigger brother, the Z87-GD65, for which tutorials look to be readily available.

 

[Bubbleawsome]

I think the MSI Z87-G41 just doesn't have overclocking features beyond OC genie. All my voltages are set to auto (Can't change) and my multipliers are set to stock. (Also can't change.)

That kinda sucks.

 

[crashtech]

Maybe an MSI owner will come along here. You might want to try posting your question in the MSI Intel Board subforum.

 

[Bubbleawsome]

Turns out you need to use the numpad +/- not the ones near backspace. Now at stable 4.2 at 1.1996v. Isn't there another voltage I new to change? The MSI BIOS is worded funny so it is hard to tell what is what. Something like the uncore and LLC? I don't have any LLC options. :|
