loadline calibration usually boost cpu v,it wont boost it while in the bios,only in windows

same as power saving wont work in the bios

yeah i noticed that mate in the bios, showing 1.28v and 1.28v on the multi
windows bumps it up by .10 though its nothing to fart about

What is your v core at for 4.7ghz

1.379v

 

[setter]

How much does input voltage play into haswell overclocking. I sold my old 4770k to a fella on the forums here. 4.6ghz on 1.25 vcore, i got 4.5 on 1.275v. Fella informed me today that he delidded it and stuck mx4 on the die and got it to 4.8ghz on 1.285v with temps of 86c max under IBT. There must be some setting ive overlooked when clocking haswell chips?

VRIN, cache, vcore just dont be scared to push them, with my 4.7ghz my voltages are 1.65v dram, VRIN 2.05, VRIN LLC extreme,cache 1.29v, vcore 1.379v, PWM phase extreme performance, VRIN was always making me bsod 101/124, cache voltage was getting me red screens in games.

never used an asus board on this build but this gigabyte board has been super reliable

 

[setter]

On asus boards you have vcore as normal, then cache/uncore voltage, then initial cpu input voltage. On gigabyte boards the terms are different. My ram is XMP rated, but im thinking of dropping the speed down to 1600 to take it out of the equation, still run it at its rated 1.65v and its rated timings of 10-11-11-31, 2T. Slack for that speed but it should allow the cpu to clock without worrying about ram speed.

 

[vonex]

Forgot to mention system agent voltage i/o and i/d all at +0.200v I'm guessing cpu input voltage is called vrin on gigabytes boards

 

[ViRuS2k]

1.29 vring ? and 1.379 vcore ? they not a touch high lol your cpu will probably be half in life cycle @ 1.379v
im not sure 1.29v will be doing any good to the motherboard.

Interesting. When I've had BSODs at 4.7 & 4.8 it's always been 101 if it's only BSOD after several minutes of RealBench/Handbrake or 124 if it's BSOD soon after starting.

Having checked my ASUS BIOS the CPU input voltage is on AUTO and reading 1.808v. Assuming that's what Gigabyte call VRIN I might give that a bump next.

 

[mmj_uk]

just run a small ffts and after 5 minutes 59c. lol

Are you using latest version of Prime95 with FMA3? version 28.5? 59C sounds wrong if so temp should be higher than IBT not 10C lower.

25.11.build52

probably why lol i will check out 28.5

No? heat is not an issue since the chip is delided and I'm on custom water. 1.4vcore is cut off point for me it should be for every overclocker if you can keep it cool, I'm happy and not worried. I've never had a component die in the last 12year's due to voltages. infact my i7 920 is still running at 1.4vcore no idea how long ive had that lol..

lets say cpu life span is '10 years', so if i 'half its life cycle' i get this cpu for 5 years, the chances of me keeping this cpu for 2 years never mind 5 years is slim.

 

[ViRuS2k]

arghhhh well im on custom water and delided also
and i have only ever tested up to 1.3v

here is a pickle though tried to test that P95 latest version and for some reason its buggy as hell.... the second i run it or 3 seconds later my pc reboots completely shuts down no bsod blue screen lol

and i am currently running @4.8 for 24/7 usage think its a good point to be at for 24/7 and i can pass

Cinebench
Realbench
Aida32 for hours
gaming for hours and hours
and also intelburn test no issues and it pumps out an insaine amount of heat and watts
and yet it passes

but p95 instantly makes my pc reboot :/
very weird and my temps are great

as you can see

image might be a little small Squint lol

i have no idea cause temps are not a issue.

 

[vonex]

i would avoid using the latest prime95 it has new instruction set that you wont come across in real word situations, use the version before the latest i think its version 28 or 27.9 something along those lines.

first new system build in years, crazy how things have changed. Anything over 50 degs on my old e6600 (2.4->3.5/1.48v ) would have me worried, lol.

L419b577, hits 85 degs in bios with a quick test run (4.9 @ 1.33 auto volts), need to get shot of this stock cooler right quick...

EDIT: Nice to see the thermal throttle kicks in around 98 degrees...

4.9ghz using stock cooler ? Treading dangerously I'd say.

Get some decent cooling in place before you consider any sort of overclocking.

+1. Seems like the op has a very good chip though if the 4.9 Ghz@ 1.33v is stable - so decent cooling is deffo the way to go.

4.9ghz at that voltage, yeah I'd say too. Just don't want him to break it with that junk intel cooler

 

[Boomstick777]

Sat at 4.6Ghz @ 1.259v for 24/7 use. Runs cool and quiet with Antec 920 on lowest silent fan setting. Really pleased with this CPU tbh.

Read that Broadwell K won't launch until Q3/Q4 2015. Makes me think X99 is still the best option for people once it arrives. How many of you guys will be upgrading to X99?

STOP RIGHT THERE: Do not overclock using the awful stock cooler, especially not at nearly 5Ghz.
