This is a bit better dropped the clock slightly ...

Much less volts allround apart from vcore smil3dbd4e4c2e742.gif

They're the exact same chip, except the 3820 is locked, has IOMMU, quad channel RAM and 2MB extra cache and no IGP, so unless you're using GPGPU the 2600k can't keep up.

That is just flat out wrong. The 3820 is a new die built on the 32nm SB-E process. This is why it has all the SB-E parts. They didn't just graft it onto a 2600k.



I know, I was meaning internally, exact same cores in the exact same config but with more cache, no IGP and two extra RAM channels.

Not like SB-e which is the exact same cores in a slightly different config. (ie. 2-4 extra)

They're not the exact same cores, what the hell?? Read what I wrote. Hell go google it. Everything is different, transistor count, die size, nevermind its built on the SBE process and not the SB process.

They are. There's probably small tweaks, but they're both built on the 32nm process...And they are different dies, but the same cores. (ie. Sandy Bridge, as Intel doesn't provide us with a separate name for the actual core like AMD was)

I suggest you read up on CPU design...It's much like how Thuban, Deneb, Zosma, Heka, Callisto and Llano all are using the exact same Stars core in different configurations with slight tweaks, all of the 32nm CPUs on 1155 and 2011 are Sandy Bridge cores with different support components and differing core amounts, iirc the Pentium and i3 have a few extra things disabled that lower IPC but apart from that it's why IPC performance is so uniform across Intels range.

The individual cores are virtually identical, but the IMC, System Agent, various I/Os, and basic layout of the processor die as a whole are very different between SB and SB-E. These differences do change how they OC and how they react to tweaking.

For example SB-E in general tends to not need as much VTT, PLL, or vCore for the same clocks as Sandy, but often needs more VCCSA.

Thats a very good overclock mate thumb.gif and very good temps knowing your ambient hovers around 30C WellDone thumb.gif

1.4v = 7 years 1.5v = 4 years 1.6v = 2 years with ss, as long as temps aren't hitting over 80c

I know this is from a long time ago, but wasn't sure if this was addressed or not.
Are the numbers you give for 24/7 100% cpu usage?
Also what temps?
