Overclocking with M6330v3 (K7T Turbo)

[phantom505]

I have read that the L1 bridges SHOULD BE open when attempting to overclock on this motherboard. Has anyone else had this experience? Also, if you have PLEASE tell me how you did it. Especially if you gone from 100 to 133 on the FSB. Here's what the article said:

**An MSI 6330 mobo oc'd by manipulating bridges only would not boot until the L1 bridges were opened, indicating the mobo had been interfering with the BP_FID bridges' settings, which was cleared by opening the L1 bridges. Have no idea of the nature of the interference. This experience also clearly confirms that open L1 bridges do not lock the FSB Multiplier, but simply prevent the mobo from over-riding or affecting other signals on the BP_FID signal busses. Please don't bug this guy, I have already emailed him, will post response if any. Here is his page.

EDIT: Sorry that this might be the third or fourth post like this. But it seems to be a common problem. Hope that article helps.

that's not true.. my L1 bridges are closed using defogger kit so that i can use all multipliers... if you leave the L1 bridges open, the only way u can overclock is by changing the FSB... my K7T Turbo works just fine when i overclock by changing both multipliers and FSB

Did you overclock with the 133FSB? What bridges did you connect, and possibly most important, what version of the BIOS are you using? Some seem to work and others don't.

Hello Tom, just to clarify first.......

The reference to having to open the L1 bridges on our page 2 came
out of a hard mod on an MSI 6330 mobo that had absolutely no support
for changing the FSB Multiplier...and...the hard mod, "correctly"
opening and closing "both" L3/L4 "and" L6 bridges, was not working.
So as a "last resort" we suggested to the correspondent that some
unknown circuitry on the mobo "might be corrupting" the L3/L4 signals
on their signal busses via the closed L1 bridges. Turned out that
opening the L1 bridges worked, but correspondent never investigated to
discover the nature of what was connected to the L1 bridges on the mobo,
and we have no idea if the above applies to your ver 3.0.

You want to drop the multiplier to 7 or 7.5 and increase the FSB to 133,
and assuming you have the same problem as original correspondent, and no
dipsw's or jumpers support for oc'g on the mobo....

You could try what our correspondent did...completely "reset both" the
L3/L4 FSB Multiplier, and L6 FSB Multiplier "ID" bridges/settings.
This would have to work, (if cpu is capable), and if not you could also
raise Vcore by closing one or more of the L7 bridges. This might be trial
and error opening and closing the various bridges to find the setting
which both works and satisfies your expectations. (Assume you have
support, jumper or bios, for setting FSB = 133mhz).

Our site is an excellent resource, as you are aware, for this kind of an operation. If you try this, be sure that BP_FID L3/L4 settings = the FID
L6 setting. Doing "both" is the key, and remember that the
correspondent's experience required open L1 bridges, for some unknown
reason.

Hope this helps, and we'd appreciate knowing how it all comes out.
