Revisiting Sandy Bridge VCORE "safety"

[RussianSensation]

. . . but we expect to see a socket 1155 IB? I think that was pretty well confirmed . . .

Ya, if you read my post, I said I doubt we'll see refreshes of 2500k/2600k on 32nm.

Understood. Even for an Ivy Bridge 22nm Socket-1155, the skinny on the street noted a possible need to upgrade "firmware" as well as BIOS for compatibility with our Z68 boards. I guess we'll just have to wait and see. But a company like Intel knows what it will do in a future and time-horizon of at least a few years. It's in their interest to sell more CPUs even if it doesn't force users to migrate to newer chipsets. The latter are in the mobo-makers' revenue-stream as well as that of Intel.

We probably won't know for sure until the "fat lady sings. . . " In this market, the fat lady isn't singing a reluctant duet with nVidia . . .

Ever noticed the much less talked about mobile SB quads? They are slower than the 2600K yet priced significantly higher. Intel knows where's the bulk of their revenues lie, and it ain't in desktop CPUs. Heck, it's a miracle the 2500K was even at $200 to begin with, probably just throwing a bone to us.

Yo, Aigo . . .

Per that 990X in your last remark . . . . is that a "fixed" voltage for 24/7? What's your view on how Speedstep and "Turbo Mode" or "Turbo-Boost" might change the longevity in "warranty units?"

Speedstep and "Turbo Mode" do not exist for the overclocker like me.

Its either ur @ 100% dyno... or you go home! :biggrin:

And yes its fix'd voltage.... meaning with load line calibration, i rarely see very little if any variation on vcore....

Also im on a Classy E759


I also have my 2600K on the M4E... I have yet to kill it, but its been at the same voltage.

I have lost 2 gulfies @ 1.4 and 1.45vcore, but they were subjected to constant load.
I dont think im gonna subject another cpu @ 1.4 under constant load again...
1.35 and 1.375 is doing good @ constant load even, but 1.4 from my observation is where the temps on a 2600k tend to take a spring jump upwards...

Unless the swings in voltage have an impact, I only guess that there is less degradation of the processor over time. That's just a guess.

I don't know what limits there are to OC'ing in "VCORE Auto" mode with EIST enabled, but I've been no less able to control my voltage to a minimum and reach respectable clocks. It will do 4.74 Ghz without a lot of trouble. At that point with TM1 enabled, it will throttle at the Intel 72.6C threshold. The load voltage may be as high as 1.34V. I think the momentary Turbo-speed "idle" was shown at around 1.38V. There would be an unmeasureable spike that would take it a tad higher.

For 24/7 this month, I'm running at 100 x 46 = 4.60 Ghz. I'm guessing with your water-cooled rig, you made it past 5.0 Ghz? 4.9?
