Question of 2500k

i got a 2500k, with giga-z68x-ud3h-b3 mbd. i oc it to 4.6ghz under 1.33v, load line 5, and all others are auto. it's quite stable.

however, i got something wired. i am in ubuntu 10.4 64 bit system, kernel 3.3.1.

sudo dmidecode -t 4 command will provide me information about this cpu.
and following is what i got:

# dmidecode 2.9
SMBIOS 2.4 present.

Handle 0x0004, DMI type 4, 35 bytes

  1. max speed is probably max turbo speed which is set in the bios. Obviously you've bypassed that. LOL

    Otherwise I think linux needs to catch up with the i5
  2. i think i disabled turbo, and kernel is very recent stable one, less than a month.
    it should support i cpu pretty good.

  3. Might be a BIOS bug since that tool is getting data from DMI. Try updating it and check again. It's probably not affecting your performance at all however.
