i7 3820 - 4820 Overclock Club - Page 137

post #1361 of 6491
Interesting. My CPU[/mobo?] didnt seem to care how I reached clocks. By that I mean, 37x130, or 39x125.

However I find that either way, without crazy voltage, my CPU is not linpack stable in any of my settings. Doesnt really matter, does it? As long as its stable in normal use, the lower voltages/temps are better for the CPU than being 100% stable, right?

Been messing some more around the 5ghz mark. Here is my results after an intel burn test

I assume these 3rd gen i7s overclock a bit higher with more ease. Not so sure about all the technicalities though.

Clock for clock is about the same as a 2600K/2700K, but does not go above 4.625-4.75 GHz as easily on air or cheap closed loop WC, as it has a partially locked multiplier (43x).
You overclock with block/strap + Multiplier with the SB-Es, so you do 125MHz x 37~38 multi - this is the cookie way for the most of us.
The only advantage is that it has more cache, that is already good enough in SB/IB LGA 1155s, so it takes the lead here and there.

The Ivy (3rd gen 1155s) are generally faster clock for clock, but it lacks expand-ability (if you want to go more than 4 cores, more than 32GB of RAM and tri-quad SLI/CX) and future-proofing - IB-E will still be s 2011 with the socket and current mobos still supported well into 2013-early 2014 with new CPUs. LGA 1155 is phased out with the next gen of intel i5/i7s being LGA 1150.

For general computing and gaming, the 3820 has no real advantage over the 2600K/3770K.
It just buys you the option for a 6-8 core upgrade in the future. It is also cheaper to buy (comes with no HS tho), so if you catch a deal from Microcenter or the likes (used to come with $50 savings if you would bundle it with a X79 mobo from them, as I did), you actually pay pretty close to what you would pay for a LGA 1155 i7 + a decent Z77 mobo.

i got 5.2 on air stable and almost 5.4 with some cores disabled
I should game.

Running at 5 GHz stable on a h100 closed loop setup, pictures of temps/cpu-z posted up above....
