I've had my i5 2500k setup up and running for a week and I'm noticing something odd. Right now the machine is oc'd to 4.0ghz and if I load up real temp 360 I can notice that on two of my cores the temp is about 6º to 7º higher than the other two cores. Is this normal? Should I maybe try re-seating my heatsink to get better contact?

That's normal, don't reseat your heatsink. If you were to run a stress test on the CPU you'd probably see the cores settle at a temperature within a couple degrees of eachother. Because the cores are on a single piece of silicon AND covered by a heat spreader, there's no way that poor heatsink contact would cause higher temperatures for some cores over others.

Is Ivy Bridge still coming this year or has it been pushed back to next year and will it be backwards compatible with Sandy Bridge motherboards?

And one more question: How far can you overclock a i5-2500K on stock voltage on average? I thought I read in the 4.4GHz range but I wasn't sure. Maybe that was with stock cooling not stock voltage but I'm not sure.

According to Asus, about 95%+ of i5-2500Ks make it to 4 GHz, 50% to 4.4 GHz, 10% to 4.8 GHz, and 2% to 5 GHz. No word on whether that's stable or just "running", though, and that's without regard to voltage settings. There isn't really a single "stock" voltage for a Core i processor. They'll jump all over the place thanks to speedstep and turbo boost. A stock i5-2500 can jump from .7V to 1.35V over the course of its operation, fine-tuning voltage as both power states and the individual chip itself dictate. Standard "full power no turbo" power is at around 1.21V +/-.1V, though, on most chips. "Auto" settings on most non-Intel motherboards will crank up to about 1.3V at that same power state, but adusting voltages is more about offsets from a non-constant baseline rather than selecting a specific voltage.

I have a slight problem with overclocking my rig. On cold days I can get 4.5Ghz easy but as the weather gets warmer it ends up rebooting on startup and automatically reducing clock speed to the next lowest 0.1Gz. With the 25C days recently I can't get above 4.1Ghz. i5 2500k in an Asus p8p67 pro with 4 x 120mm fans. One front intake, one rear exhaust and two in push/pull on a hyper 212+ heatsink.

Well then here's to hoping I get one of the 2% that can hit 5GHz but I'll be happy with 4GHz. Just 4GHz quad-core is   for me.

Any one else have problems with S3 resume failing when overclocked? I have a 2500K on a P8P68 Pro running at 4.8 GHz at 1.375V. Completely stable (20 hours OCCT, etc.), SpeedStep/EIST works without a hitch, and the machine will suspend to ram OK, but will not resume (fans turn on, but screen stays blank). Any ideas?

I'm having trouble updating the firmware on my spinpoint f3(HD103SJ). I tried burning the update to a CD as is and then as an iso. Both times it gave me something like "please insert bootable media and press any key" Also what does Samsung mean by: quote:2. Please connect Target HDD to Primary / Mast.

 You need to run the program from within a DOS environment via a boot disk. This can be a LiveCD or LiveUSB of FreeDOS or something, but I have not entirely mastered this procedure, myself.

Mystery error. The motherboard I got from the Sandy Bridge recall just powered down in the middle of normal use after a week, and it wouldn't do anything afterwards. Replacing the motherboard made it power up again, but it lit the CPU, memory, and video error lights in sequence and constantly power cycled. It seemed like something Intel had seen before, as they replaced the processor with no further questions after hearing that, but they wouldn't tell me anything about it. I kept Vcore on auto, except for once when I pushed to 1.4V for about 90 seconds to hit 5 GHz unstable for e-peen points. E: Christ, this thing must be hand-picked. I'm doing burn tests, and it's hitting 4.6 GHz stable at 1.28V, running 15C cooler than the last one. Bluescreen at 4.8 GHz, though. Don't care, that's a far sight better than 4.8 GHz at 1.35V doing burn tests at 75C. Factory Factory fucked around with this message at 09:12 on Apr 26, 2011 |

Anandtech just published some additional details about the upcoming Sandy Bridge-E processors and X79 chipset. Disappointingly, only the hex-core processors will be unlocked, the quad-core CPUs are limited to 6 bins above the maximum Turbo frequency, or 4.5Ghz. I'm curious to know what the actual chipset<->CPU bus is, and how many PCIe lanes from the chipset are actually available for devices.

So I'm poking around the UEFI BIOS on my MSI P67A-GD65, just looking at all the piles of settings and getting myself properly amused by the fact that I think I can play loving Tetris in my BIOS, but 90% of the actual options are completely undocumented with an obscure name. The one I'm most curious about right now regards power management for the CPU itself, and I'm presented with APS(Active Phase Switching), Intel SVID, and Disabled. It's currently set to SVID, and that's cool, but I find myself curious what the difference is. So I get to googling and all I actually have is a pile of overclocking forums saying to disable power management altogether so that the CPU constantly has all the power it could ever want. I don't really feel like overclocking my 2600k on the stock heatsink, maybe once I upgrade soon, but for now I'm happy to let the thing underclock itself when I'm just typing posts on forums. So that leaves me still pondering what exactly is the difference between APS and SVID modes, and hell, should I switch?

From some quick Googling, when set to Disabled, the core voltage will NOT be reduced at idle, and all power phases will be powering the CPU. When set to Intel SVID, the core voltage WILL be reduced at idle, and all power phases will be powering the CPU. When set to Active Phase Switching, the core voltage will NOT be reduced at idle, but the number of power phases powering the CPU will be reduced according to load. HOWEVER, there have been a number of fixes to power management, so it was possible that the core voltage not being reduced at idle in APS mode was a bug at the time it was tested. To expand on power phases: The CPU is powered by VRMs that convert from 12V to the CPU core voltage. Because nobody makes a VRM that can handle 100W+ AND will fit on a motherboard, they use a bunch of smaller "phases" operating in parallel. The downside is that each phase has some overhead, so if your CPU is sitting idle then you'll be wasting a lot of power (compared to the trickle the CPU is drawing) to keep each phase powered up and converting energy. The idea with APS is that if the power draw is low enough that it can be handled by less than the full number of phases, you shut off the unnecessary ones and concentrate the load on the remainder, eliminating the power overhead of the unneeded phases.

I believe that has to do with exactly how and when the power distribution system gives the processor more juice, analogous to the Asus boards' VRM systems. Blah blah nutshell version: APS lets you use all those fancy power phases (and their higher specs, on MSI boards) above the 4 the processor handles natively (i.e. according to Intel spec) that you paid for on your motherboard, and this allows a wider range and finer tuning of Vcore settings that can be provided with sufficient current and switching responsiveness while still using the full range of power management features (and being a good bit more efficient doing so, to boot). Re: those power management features, nuttier overclockers say to disable all sorts of stuff related to power states and phase switching to avoid all of the (vastly overblown) potential pitfalls of transitioning between power states and microsecond-scale delays of some kinds of power management tricks. They're content to let the processor run with all the thermal management of an Athlon Thunderbird, i.e. all on all the time, drat the torpedoes. This means that the processor doesn't slip into idle state when nothing is being asked of it (with a ~100 microsecond delay to come back up to speed), and it doesn't run at a 1.6 GHz low-power/low-voltage mode when only little is being asked of it. It just slams home the volts every moment it's operating. This will mostly make small differences in synthetic benchmarks and maybe an extra +1x or +2x, best case, on your top possible multiplier setting. Not worth it.

I'm sitting at 4.8 stable with all the little power saving features on, and you're absolutely right, it's not worth it to turn off all that stuff. Having a CPU that sleeps around at ~1.6Ghz and can throttle up to 4.8 in an instant is pretty sweet.

I posted earlier about the spinpoint update thing. Fumbled around with different methods for awhile but was never able to actually run the patch once I was in the DOS environment. My p8p67 pro arrived and I said to hell with it and plugged it in anyway. It recognizes it just fine, no problems there. The board did however have problems recognizing my ram, which is this stuff. It would only recognize one stick and anymore would cause the memOK light to come on and not post. I reseated the 212 Plus and then it let me use both sticks but only if I set them to 1333. Then I tried to add the other 4gb, which is this stuff. That caused the the ram light to come on and not post again. Maybe it's still the heatsink. Any ideas?

It'll be the only choice for doing an enthusiast-based server platform (currently cannot deliver more than 2 x8 lanes, as the PCH maxes at 2 x4). It's also the only way to do tri/quad SLI, but that's a whole different box of crazy, heh. Right now I'm going to try a P8P67 Pro + i5-2500K under Solaris, and see how that goes. Might get interesting with # of drives though, since I can only operate two controllers at most (2 x8), and the 3G ports are dead.

Seems like Intel heavily gimped the SB mobile i3s to only a mere 2.1GHz, while the mobile i5s can turbo all the way up to 3.3GHz. I think they realized Arrandale i3s are simply too good for the price back then.
