1.424V Vcore damn you're brave.

And I lol'd @ 181W CPU package power, that's like Ivy-E level power draw. Congrats on the 4.8 OC though

"1.424V Vcore damn you're brave."

Silicon Lottery is selling binned 4.8GHz@1.424V 6700K's for $540.00 a pop and they're currently sold out (I paid $320.00 for mine from MC);

In terms of Vcore, this is Skylake, not Haswell, IB or SB.

"And I lol'd @ 181W CPU package power, that's like Ivy-E level power draw."

Well, I did indicate it was Prime95 28.7, one of the "hotter" stress testers around. Here is a four hour run of a much less aggressive stress tester. CPU package power max is only 117W;

Well SB I'd have no issues running 1.45V for 24/7, and 1.4V for IB (I ran my old 4930K at 1.4V for an entire year without issue). Haswell's kind of an oddball since the FIVR just pump out too much heat to really push Vcore hard. I know Skylake isn't Haswell but 1.4V+ on 14nm? I just don't know.

Btw the P95 comment wasn't meant to be a slight, I was genuinely impressed at how much power the quad core was sucking down.

Apparently Asus and Intel suggest a max of 1.45V. He's pretty close to that. Personally I thought the voltage max would have dropped due to the die shrink but it seems to be hovering around that point for a few years now.

Nice job with the delid. That's a pretty massive temp drop you got there.

1.424V is fine if temps are in check, as long as 1.424V is the measured voltage, not what was set in the BIOS.
Asus stated that for a normal chip, 1.43V is ok on air if not hard benching and 1.45V is ok for water cooling.
Delidding has a similar effect to using water on a normal chip, those temps are great!

Ah, Dayaks got there first with the Asus quote :)

Did you try OCCT ? My OC was stable in Prime95 but not in OCCT.
Would this bring same effect on e5 1620 @ 4.5GHz ?

Op, can I ask about the delid.
What was the procedure you used?
Was there any problem adjusting the heatsink height lower?
Did you take any pictures while you did it?

I fancy having a go :)

No, I didn't try OCCT. The die may be soldered to the IHS if E5-1620 is a Sandy Bridge Xeon CPU.

"What was the procedure you used?"

Razor blade to separate IHS from PCB and IHS resealed when done like the original.

"Was there any problem adjusting the heatsink height lower?"

Not certain whether you're referring to a bare die setup or you're referring to the IHS making contact with the PCB before making contact with the die. Whichever, bare die was not used and IHS made contact with die before making contact with PCB.

"Did you take any pictures while you did it?"

Yes, but there are so many videos and pictures already out there. Search You Tube, also, here's a link to a bare die setup (Ivy Bridge), just use like 1/20 of the amount of CLU shown and use some painter's tape to mask around the die when applying;

There's usually a height differential between the original uncut IHS and the replaced IHS after you cut it off then re-place it with your thermal compound of choice. Not a HUGE one. But enough that some thermal solutions won't make good contact with the IHS plate afterwards.

I've read accounts where the rim of the IHS made contact with the PCB and had to be sanded down but that wasn't the case here. Made certain of that. Wondering whether all traces of the old sealant were removed from the PCB and IHS in such cases. Almost clean as a whistle here;

Wow.. amazing results.. I got like a 16C drop when I did my 4770K but I also have my system built to run silent. This makes me want to delid my 4790k...

Nice job. The delid temp drop is the impressive thing. That and the professional clean way you did it. Thank you for sharing with us. :)
