Hi guy

i’ve found a secure method for overclock Dual Xeon E5440 via software with supermicro X7DWA-N (this MB support FSB 1600)

download this software

LINK

Set ICS932S421BGLF or ICS932S421EGLF
Set ULTRA ON
Press Get FSB
Move the long slider for change FSB
My RAM is :frowning: 333Mhz so with 400Mhz windows restar. I succesfully set 360Mhz.

that’s all

My test is

17min 31 (@2.83) sec vs 16min11 sec (@3.00)

i know that is a little change, but with 400Mhz RAM i hope to overclock 3.2 and up!

E5405 - 2GHZ FSB 333
E5410 - 2,33GHZ FSB 333
E5420 - 2,5GHZ FSB 333
E5430 - 2,66GHZ FSB 333
E5440 - 2,83GHZ FSB 333
E5450 - 3GHZ FSB 333
X5450 - 3GHZ FSB 333
X5460 - 3,16GHZ FSB 333
E5462 - 2,8GHZ FSB 400
E5472 - 3GHZ FSB 400
X5472 - 3GHZ FSB 400
X5482 - 3,2GHZ FSB 400

I generally dont overclock stuff. I think the extra speed would hardly be noticeable at the possible cost of melting the cpu eventually. Too much risk in my opinion.

Me too :slight_smile: . I run stable on 3.2 with 1hrs render. There is a 10% increment in render speed, but +10°C and much more risk.

But now also Xeon can be overclocked :slight_smile:

Try to lower the mem speed in bios or change the FSB/MEM ratio to have slower ram at start up.

There is btw something called the FSB wall, which depends on your chipset and mainboard. I have a badaxe2 and i can increase the FSB in small steps only to ~360mhz - and the next step would be about ~400mhz and more, but since i’m on air i don’t even test it.
