FSB wall with GA-G41M-ES2L

[Duvie]

I call it a wall and not a hole, because I have tried fsbs all over with much lower multipliers and lower then stock speed...NO GO!!!

I also found a few comments about similar findings on the net with reports of the wall anywhere between 335 to 345....have latest bios..cannot find beta ones


I hit the hard wall at 340...after that 5mhz more fsb cannot be achieved even without a full .1v raise in vcore. Also raised termination voltage....as well as kept memory well below stock speeds. Cannot post with 345 even if I drop the multiplier so the cpu is running below stock speed.

I tried 400, 401, 402, etc with multipliers from 6x to 8x...no go...no post.

Any ideas....

MOst other settings are default....anything I should be looking at? should try?



Base info:

E6300(pentium dual core)(45nm) @ 10.5x340=3.57ghz at 1.3v set in bios...cpu_Z reports 1.26 to 1.248v under load....
Small FFT Prime95 stable for 12hours
DDR2-6400 set at 680mhz spd settings 1.9v
PCI-Express locked at 100...tried 99, 101, etc...
Temps at 3.57ghz 64c....

After an ongoing love affair with Gigabyte boards I'm starting to go right off them. Admittedly these are cheapest of the cheap boards we're talking (in my case G31M-ES2L), but these odd overclocking issues seem common to them.

Mine will only operate in small FSB bands around the "standard" FSB frequencies - 200, 266, 333. More then 10MHz away from those values and the board just won't post.

There were some random things that I tried when I was trying to get any overclock at all, when I first bought my board. Disabling USB legacy keyboard/mouse/storage options in BIOS was recommended by people on a few forums.

Different chipset I know, but similar symptoms. Curiously my older almost-idental board (G31M-S2L - note the lack of Energy Saving E) didn't show any such issues.

I have the same mobo as WildW and it is at 272 for the fsb so only 8 from the 266. I have tried other settings but have had to many problems. My e5200 oced to 3.4 does just fine. Rock solid.

I've got the same mobo OP, currently running my E5200 @ 333x10.5 with low voltage on the vcore, and only one bump on the FSB Termination voltage. I haven't tried higher then 333 though as I'm running a little hotter then I'd like on the stock cooler (in the 50s under load) but I hope to get a real heatsink around Christmas.

Sounds like it.

Some CPUs do have pretty low FSB walls themselves though.

For example, with my Pentium E5300, i cannot even POST @ 350, this on a mobo i can run stably over 450 w/ quads.

Yup. FSB wall not only exists on boards but also exists on CPUs themselves. You can try the BSEL mod, but that should be the last resort.

You can try the BSEL mod, but that should be the last resort.

I have actually had the BSEL mod "fix" FSB walls on some boards. I recall doing that BITD with P965 chipset boards and 800MHz FSB CPUs. Worked like a charm.
