    SB Overclocking Thread

    Makes you wonder why Intel lists 1.71V as the minimum for this in the datasheet. Are there any adverse effects from undervolting other than possible instability?

    FYI, the Black Edition in your link doesn't appear (based on the pictures) to be the same as the Black Edition in the article. I think this is the one that you want: http://www.newegg.com/Product/Produc...82E16814150520

    If you pay more, you get more. Why buy the 570 when the 580 has even better performance?

    You need to change the turbo multiplier. I was also confused at first because there are at least three different places in the UEFI where you can set the multiplier, but the turbo multiplier seems to be the only one that actually has any effect.

    vdroop with the GA-P67A-UD3 board

    Sounds normal to me. Vdroop is a safety mechanism that is part of Intel's design. Read the following for a full description: http://www.anandtech.com/show/2404/5 As the article states, you can overcome it by using load line calibration, but doing so circumvents a safety protocol.

    SB Overclocking Thread

    For anyone that's overclocking using voltage offset with EIST and C1E enabled, I recommend performing the following test: open Prime95; set CPU affinity to a single core (CPU 0 w/o HT, CPU 0 & CPU 1 w/ HT); now run Prime95 Small FFTs with enough threads to get 100% load on the core. My...

    Sandy Bridge Safe Voltage Confusion

    This is the source that came up with that figure: http://forums.overclockers.co.uk/showthread.php?t=18227647 Whether they're credible or not I don't know, but just about every review of Sandy Bridge that I've read (including AnandTech) have used more than this "safe" voltage in their...

    SB Overclocking Thread

    Does anyone have a solution to this that doesn't involve disabling EIST and C1E? Or do I need to apply more voltage despite being fully stable when all four cores are loaded? Edit: I have a hunch that it has to do with LLC activating only when all four cores are loaded.

    P8P67 Overclocking questions.

    I was wondering why my CPU never goes above 95W in CPUID Hardware Monitor (not sure how accurate it is). I'll try setting it to 110% to see if it makes a difference. Also, see the "official" guide, which makes no mention of this option: http://hardforum.com/showthread.php?t=1578110

    SB Overclocking Thread

    Never mind. Setting CPU affinity to one core and running prime95 with one thread brings the system down. It appears that having one loaded core doesn't bump up the voltage as much as it does with four loaded cores. I guess leaving voltage on auto is not an option after all.

    SB Overclocking Thread

    My 2600k is doing 4.4 GHz at 1.3 V on an Asus P8P67 Pro. I had to set LLC to high (50%) to get it completely stable. It doesn't completely eliminate vdroop, but it can maintain a load voltage of 1.28 V. I usually hesitate to use LLC because of the theoretical risks, but I really wanted to get at...

    Sandy Bridge Turbo Boost - how long can it be active?

    If Long Duration Power Limit is left on auto does that mean that the board will restrict the CPU TDP to 95 watts? I have mine set to auto, and it never seems to go above 95 W in CPUID Hardware Monitor (not sure how accurate this is) despite being overclocked to 4.4 GHz. Should I increase it?

    P8P67 Overclocking questions.

    I'm also using the latest non-beta bios. That's what I meant in my earlier post about seeing only the load voltage in CPU-Z when turbo kicks in. The value in Core Temp is the VID, and I think that's the actual voltage applied when set to auto (and the offset uses that as the base). So if you...

    P8P67 Overclocking questions.

    Something to keep in mind when you have EIST and C1E enabled is that unless you're using LLC, the voltage is actually higher than what you see in CPU-Z because turbo mode is only activated under load so what you're seeing in CPU-Z is the voltage with Vdroop. I don't know if this is important or...

    P8P67 Overclocking questions.

    As you have already noticed, if you manually set the vcore then the vcore doesn't change dynamically with EIST and C1E. You can use the offset feature to add to or subtract from the voltage specified by your VID (used when it's set to auto), which will preserve the voltage throttling at lower...

    Then isn't this a problem when using the offset? For example, say I set the multiplier to 40x. My VID for this multiplier is about 1.34 V, which is probably more than necessary. I can use the offset to subtract from this, but then that might create instability at low multipliers when EIST and...

    How is this "standard" value determined? When I use the offset feature on my Asus P8P67 Pro it appears that the offset is applied to the value determined as when set to Auto. I'm curious about this myself. Perhaps it has something to do with VID?

    My stock i7-2600k with a TRUE 120 heatsink in push/pull configuration is getting 56C at full load; ambient temperature is 19C. I haven't tried overclocking it yet, but it seems kind of high to me.

    Automatically download all security updates for WinXP?

    I slipstream the Xable pack by using nLite and I'm not sure about RyanVM as I haven't used it myself but I think it includes its own integrator. As for why Xable is smaller, it's because it only includes the critical updates whereas RyanVM includes a lot of extras.

    I'm not 100% certain but I think you need to download each update manually. Some people have already done the work for you though; see xable.net and RyanVM.

    E2xxx and E4xxx overclock thread

    Unfortunately 3.6ghz is not stable for me at 1.495V. Going to 1.515V would probably do it but I'd rather not exceed 1.5V. I'm probably gonna settle for 3.5ghz at 1.455V for now. Do you mean setting 1.505V in the bios, or the adjusted voltage including vdroop?
