E6400, 680I chipset... adjustable multiplier???

e6400 processor
ecs pn2 sli2+ mobo
512x4 geil 667mhz ram
6600GT x2 sli
36GB x2 sata raid-0 wd raptors
250GB x1 sata jbod maxtor

first time playing with anything faster than a 630 on an nforce 4 board... and i start poking around in the bios.... noticed the fsb options are quite extencive... but one thing caught my attention... the multiplier is adjustable... mind you i payed 250 bucks for this "oem" 6400... cause the retailer didnt have intel boxed... but what caught my eye was that i could change the x8 to x20 if i really wanted to.... did i find a diamond in the rough?? did someone at intel put a chip where it wasnt sposed to be?? or was some n00b at the retailer swapping parts???....

as far as i know, the only chips that could swap the multiplier were enginering samples and extreme editions... has this changed??? or did i just get lucky??

  1. Lucky bastard. Saw an E6300 with unlocked (5-14) multi on eBay a few weeks back, still a rare luck of the draw. Wonder how many of them sneak into lowly Dell's and HP's and will never be used to their potential.. :(

    Mind pushing it up to x10 or something higher and posting a screenie or two? Or selling it to me...
  2. just as i posted that... i got curious... REAL CURIOUS... must be a bios glitch -_- cause the only thing that posts is x6 x7 and x8 anything else is a solid beeeeeeeeeeeeeeeeeeeep and reboots into POST safemode -_- damn :( so i played with the FSB... 1066 to 1200 (wimpy lil first step) and tested with aquamark3 (i just use it cause its cool to watch)

    so anyway... on an nforce4 x16sli board... these 6600's got TOPS 74000.. with this e6400 at stock speeds it skyrocketed to 96000, and now with 1200fsb it jacked to 104000...

    man i really wished this was an unlocked mythical processor -_- GRRRRRRRRRRRRRRRRRRRRR
  3. Hehe, I was thinking the same thing when I saw my ASUS board went up to 20x. Alas, my X2 4200+ could not run above it's default 11x multiplier.
