Finished up my newest build nviida green air 540 i7 haswell...after strking out on the chip lotto after bout 3 times I settled with this one still have my 5ghz baby though redface.gif

4.8ghz - adaptive vcore 1.46v load 1.475

4.3 uncore 1.23v

SA voltage +.300 IO voltage +0.150

VCCIN initial 2.0v eventual 2.0v

delied with CLU max temp under load 78c 3 hours IXT idle av. 27-31

average game temps 50-70 ambient 33-34c

and of course intel tuning plan incase she poops out after couple years thumb.gif

I have found when running 2400mhz or above on the ram and also running SLI with other pcie device such as my asus ac adapter...I need above offset of + 0.250 at minimum or I get issues with booting in etc.

also with the system agent voltage raised I am able to slightly lower the vcore and I mean slightly like 1-2 notches and this negligible...but required.

I also found the chip/system did not like below 1.96 input voltage / vccin or it would also have issues booting and stability.

Ty for info

What about the IO volts?

I have ram at 2600 with SLI and I don't have that offset voltage. What mobo are using ?

using the Asus maximus formula

for the most part auto worked well up to 4.7ghz but with this chip etc to get to 4.8ghz I had to increae system agent voltage etc.

and Cyro999 I also did the IO by +0.0150v

id ay for the most part auto should handle everything ok unless pushing the chip hard etc

Why is there a freakin reply button on all comments when youre only leaving a comment in the thread without quoting? Its driving me insane!
Also dont know how to erase previous comments..

There was a quote to it.. I just followed what Cryo said and it was at uncore 33 which was stable at 37 and 40 but not 41.. Didn't have 35

Did you leave your EIST and C-states on or off to achieve such high OC?

I also have the M6F (Bios V1102) and Dominator Platinum 2400MHz CAS9 and I'm wondering what other BIOS settings to tweak to push it past 4.5GHz @ 1.35v w/2400MHz RAM.

Chip is delidded with CLP paste and running H100i.

Based on my BIOS settings what would you recommend me tweaking to get somewhere around your cruising altitude of 4.7/4.8GHz.?



















































post #10589 of 19540
sigh I do have a unlucky chip. Everything is stock besides the core which is @ 44x. Also uncore set @ 33x.

1.35v = 40 minutes prime95 before restart (error 101)
1.375v = 2 hours prime95 so far

I'll be bothered to push more voltage through this cpu as I want it to live for awhile. This kinda blows, hoping for 46/48x with this voltage frown.gif

The delta from 44x to 46x is only 6%. Not going make a difference really. I know it sucks. My first one wouldnt break 44x. its in my 2nd rig now (my sons) and performance in games is the same as mine at 47x. So luckily haswell is already really powerful at stock.
