    Default What QPI/VVT Range Is Safe For EX58 UD5

    I am running j@ 1.4 now. I've heard that you could go up to 1.5 (SAFELY?).
    Whats your opinion.

    I just looking for my 24/7 OC. I have found that there is not much if any performance above 4.2ghz. At least I finally got my memory to run at spec.

    theres no point in clocking any higher other than for benchmark numbers,i cant notice any difference from 3.8ghz to 4.4ghz

    All of you GREAT and WISE ud5 users F11 bios is out and it has helped me drop vcore to 1.265 from 1.3000 with F10. I really wanted to test it so ran 50 passes with LinX, I'm impressed. My 24/7 OC is 4.2. Couldn't see any performance gains any higher. I was also able to drop QPI to 1.36 from 1.40. New bios info: Support new SPI flash type: MXIC 25L1606E
    Serial Peripheral Interface (SPI) faster transfer rates.
    Faster transfer rates mean controllers can execute code (XIP) directly from the SPI interface or further improve boot time when shadowing code to RAM.
    -MXIC25L80xx support 8 Mbit BIOS.
    -MXIC25L16xx support 16 Mbit BIOS.

    Just thought I would share.

    1.4v is fine, even 1.5 but for 24/7 system i would look for reducing those volts as much as possible to try to control the heat more than anything else

    if you dropped to 4GHz and reduced vcore and vtt a bit more you would still have just as an impressive OC and experience a lot less heat....

    good work with the OC...you have a nice CPU
