Short test? Prime95 blend was running 24 hours! Lol

You may want to check out this Gigabyte specific thread:

if you enable C6, C7 with Asus boards, it works the same way. well, at least on my Hero.

Ugh, this is frustrating, coming from a simple i5-750 with an ASUS board, to a haswell with an ASRock.
No matter what I do on my Z87E-itx, the ONLY way the overclock sticks is if I use the "CPU OC Fixed Mode" which really blows when I'm not needing my oc =|
Been fiddlin' around a few days now, and can't seem to get around it.

Just going for a simple 4.0 or 4.2 clock cooling and air flow are limited.

that's because of AVX. heck, mine at DEFAULT clocks and DEFAULT Vcore reaches 1.25-1.26V with Prime95. this is one effed up chip. mad.gif

i wonder if my CPU's stock TDP is more than the marketted 84W biggrin.gif

Had a solid tuning session today, and would appreciate if you updated the chart with these results as they're complete and stable.

Username: Big Texas
CPU Model: 4770k
Core Multiplier: 45x
CPU VID: 1.23v
Vcore: 1.23v (Vdroop Control 100%, vCore Override Mode)
Uncore Multiplier: 42x
Uncore Voltage: 1.150v
Cooling Solution: UNDELIDDED, H100i with Arctic Silver 5 Thermal Paste between water block and IHS.
Stability Test: IBT 10 runs, Cinebench
Batch Number: L312B326
Ram Speed: XMP 2400 MHz 10-12-12-31 @ 1.65v
Extra Information: VCCIN 1.820v, Uncore Voltage Override Mode, SA IO Analog IO Digital all Auto.



All in all, this is my daily overclock from now on as I'll only be gaming/web browsing/other unintensive things. The temps don't really bother me as IBT is probably one of (if not THE) hottest stress tests out there. Unless I get a breakthrough I probably won't push for 4.6 GHz unless I was to delid. Decent batch, was kinda a pain to fine tune and stuff but I guess it turned out ok. The H100i MAY be mounted slightly off though, but that's a whole different story (I had to ghetto mod it with washers on the backplate).

Now, some tips for you guys. Do NOT underestimate VCCIN. 1.800v would black screen me, 1.810v would blue screen me on run #7/10, but 1.820 is now stable. Uncore Voltage was the same way, I had to find the sweet spot there too. Uncore instabilities typically blue screened on about run #3 or #4/10. vCore instabilities would crash on run #1 or #2, so I could tell the difference there. Learn to know your CPU, there can be patterns that will make things much easier for you.

Thank you guys for the help, hope that I myself helped someone out, and I will definitely be watching this thread. thumb.gif

Just had to share this. Take a look at the recent maximum processor frequency I had showing in Intel XTU! lol

18408404787.62Ghz biggrin.gif

I knew i had a good chip. hahahaha

Interesting about the VCCIN crashes. I was getting a lot of crashes on test 6 or 7 when I was trying for 4.5 - now you are making me want to go back and try again while playing with VCCIN.
post #1088 of 19539
how do you guys test if the VCCIN need to be upped? you keep on increasing the Vcore and once you feel that "it should not need this much of a jump, maybe i should play with the other voltages", you do it? but do you drop the Vcore and then increase the VCCIN? just feel like there are too many permutations and it would take a decade to test all those settings. :-/

VCCIN is input voltage from your motherboard to your fivr, everything draws from it, vcore, sys agent, ring, igpu. Generally, for moderate overclocks, you dont need to touch it, default is enough. You start experimenting with it when you find yourself using high vcore/ring voltages and raise to see any improvement. Definitely dont drop vcore for vccin!

Too much of VCCIN can also provide instability. You dont want to flood your fivr with unclean power from either bad psu or motherboard.

I have a question about the adaptiv voltage...normally the voltage is only lower when you dont play games and stress test? Or? Because i play alot isnt it better to leave it at fixed mode i only have 1.2 vcore so....
