I7 4770K BSOD 1E

[Alz_D]

After re building my loop for the second time in two days (Pro Tip - make sure you put the graphics cards in the right PCI-E slots before you build and fill your rig) with a nice shiny new 4770k and Gigabyte Z87-OC I had a bit of a play with overclocking it:

Multi 45x
Vcore 1.3v
LLC is set to Extreme
Memory is set to XMP

Edit: Temps are all under 60c on Prime (I have downloaded Aida64 now as this seems to be regarded as a better CPU stress program for Haswell ?)

At lower Vcore I was getting BSOD 124 errors. At 1.3 it seemed stable on Prime - but last night I got a new one ending in 1E?

Happened while streaming off youtube of all things

Any ideas? Did a quick search and it could be Vcore needing to be upped a couple of notches?

There seem to be more settings with Haswell than I needed to play with on my 2600k - Will be fun learning (read: fiddling with stuff)

1E usually relates the vcore from what I can remember.

Should hopefully be an easy fix then. Will bump it a touch tonight and see where we end up.

Alawys handy when overclocking -

BSOD Error Codes -
BSOD codes for overclocking
0x101 = increase vcore
0x124 = increase/decrease vcore or QPI/VTT...have to test to see which one it is <----- Almost always QPI...
0x0A = unstable RAM/IMC, increase QPI first, if that doesn't work increase vcore
0x1E = increase vcore****
0x3B = increase vcore
0x3D = increase vcore
0xD1 = QPI/VTT, increase/decrease as necessary
0x9C = QPI/VTT most likely, but increasing vcore has helped in some instances
0x50 = RAM timings/Frequency or uncore multi unstable, increase RAM voltage or adjust QPI/VTT, or lower uncore if you're higher than 2x
0x109 = Not enough or too Much memory voltage
0x116 = Low IOH (NB) voltage, GPU issue (most common when running multi-GPU/overclocking GPU)
System Freeze = Usually increase V-core and test for improvement.
Universal terms
BCLK- Short for Base CLocK. This is the base frequency at which your CPU will drive the rest of the PC. The limiting factors in max BCLK will be
the cpu itself (luck of the draw) and the motherboard (luck of the draw/quality control). (BCLK)CPU Multi = CPU Frequency. For 32nm Westmere chips
it is best to overclock with chips that have high multipliers as max BCLK is low with these chips. At and beyond 200 BCLK the qpi/vtt voltage
required to post become too high to be considered safe to overclock for over 24 hours.

DRAM- Main Memory, ur DDR3, the triple channel goodness, whatever... (BCLK)Memory Multipler = DRAM frequency.

Uncore- This is in the block diagram but not written. Uncore is a frequency that the CPU handles everything from the north bridge to the south bridge.
Uncore must be at least 2x as great as the memory frequency. This can be an issue if your CPU/motherboard can not handle an insanely high uncore, so for
the record a memory overclock will affect the uncore stability. An overclock can get a special edge by pushing the uncore beyond 2(memory multi). If you
have room to OC it then go for it. SPECIAL NOTE there are substancial findings to suggest the average overclocker can increase their uncore multi by 1
and may achieve higher system stability even at mild OCs. This can even reduce voltage at higher OCs and is a MUST to consider for MAX OC.

QPI- Quick Path Interface is the memory I/O for the CPU. With CPUs like the i7 920 the low QPI rating can interfere with MAX OC. Only a few motherboards
have the options to circumvent this barrier.
IOH- North Bridge, affected directly by Uncore
ICH- South Bridge, less affected by Uncore than the North Bridge
CPU Multiplier- Explained in the BCLK bullet as a factor of overall CPU frequency the CPU multiplier represents the CPU's proportional speed to the BCLK. For a x21
CPU multiplier you would take the BCLK frequency and that's how many cycles the CPU completes before it is addressed by the BCLK

Thank you - I feel I should have found that with my google-fu prior to asking the question.

Alz:

BSOD 124 (which is usually the idle BSOD code) can be down to 3 things. Too low cpu vcore, too high/low CPU PLL voltage or it can be down to your combination fo power saving features (c3/c6, EIST, speedstep).

Cheers $ilent - I'll be having a good look tonight. Hopefully I can get it stable and then hopefully go further. Having a custom loop I'd like to think I can get higher than 4.5Ghz - I know this is dependant on the chip more than anything but it's VID isn't too bad. That first then get my 780's overclock back and stable.... Then go back to my normal day to day business of collecting steam games and browsing the daily mail web site.....

If your looking to go over 4.5ghz you might have to consider delidding your 4770k.

At 1.3v and 4.5Ghz my temps don't break 60 degrees using prime. I'm hoping I have a little more head room. See what happens later

Are you using adaptive or Manual voltage? apparently prime does something to the voltages when using adaptive mode and makes it run a fair bit higher than what you select.

Is it bad that I don't know the answer to that question. I just manually set the Vcore to 1.300v
No doubt there is a setting somewhere.

I can't wait to have a play about tonight. Have to watch the kids choice of evening film after work first though - Either gonna be "Epic" or "Whatever the 4th Harry Potter film is*".

If you set it to 1.300v that's manual voltage.
Adaptive voltage shows as an offset like +0.015v which indicates 0.015v over stock voltage.

Your at 60C max using 1.300v on haswell?

Mind sending a screenshot showing that temperature?

I think I've fluffed my numbers here. Just updated my bios to the F6 and put my numbers back in. Testing with Aida64 the temps are way out to where I thought they were. Hitting into the 70's at 1.3v

I do have the heating on but that won't have made that much difference

So not to despair - I still have a bit of room. Thinking this chip will be safe at 4.5 maybe a touch higher we shall see. Don't want it running too hot. I'm a bit gutted actually as I thought I had loads of room to play. Might actually be a bit more time consuming and need a bit more effort than I thought. I will get there.
