i have strange problem with this Gigabyte P35-DS3. when is all on defaults its ok, when overclock (example from default 200FSB to 266), i having problem with cold boot (reboot issue when is starting comp)
Bios is F4, with F6 is same thing. C1E, TM2 and EIST are turned of in bios.
comp:
E2160
Gigabyte P35-DS3 rev. 1.0
2x1024 Kongmax DDR800
Ati HD2600XT
Fortron 400W
My friend have same board with E6750 and dont have cold bug.... is this just with Intel E21XX series of cpu?
I have an e2160 and its doing the same thing on my p35 ds3r
i found solution for this problem, its all about memory devider.
example: E2160 with memory devider at 3.33 working without COLD REBOOT when you overclocking...
Left is FSB | Right is memory devider

:down: => COLD REBOOT BUG

Thanks for this, I will have to do some testing and see if i can replicate these results
This isn't a bug.
There were hundreds of posts about this last year.
This is a chipset feature. I don't remember why but it's by design.
Most boards bioses created a workaround for this; I think by managing to prevent the PSU from shutting down power to the system, while the board itself still does a "cold reset", which is transparent to the user--the power is simply not cut. For example, on asus boards, with the BIOS that prevents the "cold boot", you can STILL tell a difference between how the board POSTs at 266 FSB vs >330 FSB, including the beep and post speed (even more noticable if you have a monitor that loses the signal temporarily between boots at >330, and doesn't at 266).
