i just got my E5200 @ 3700mhz 1.47v bios 0901..i already tested the 1201 and 1301, but with those, 3700mhz needed 1.55v...
im running on 12.5x296, and cannot go over it.. i can put 1.6vcore and dont go..
on bios 0608, i was running a C2D E4300 @ 3420 (9x380), so its not the motherboard.. i think my E5200 got FSB Wall.. or that bios 0901 dont leave me go over 296fsb.. i already tried 11.5x333, 12x316, and dont boot..
who is caping, the mobo or the processor ?
The processor should be able to boot to at least 300 MHz FSb...on this setup with E5200 & P5N-E Sli I''ve noticed that if you are at for example 12.5x296, go into BIOS and try to set 11x333 - the MB won't boot, because the multiplier is STILL
12,5, which could be seen after the restart - the system displays the last CPU frequency on the boot screen and in my case its 4,16 GHz
. So my way dealing with this is as follows:
1. If the working frequency is 12,5 x 296@x,xx voltage, go into BIOS and lower the multiplyer to the desired value - for example 11. Save & exit BIOS.
2. The system boots at 11 x 296. Go into BIOS and set 310 or similar FSB /and don't forget to set the NB voltage to 1,56 or higher for this FSB/. Save & exit BIOS.
3. If the system boots - go into BIOS and repeat step 3 with higher FSB. If the system doesn't boot - you've hit the FSB wall of your processor. Restart and set again 12,5 x 296, this is important, so the system could boot at the next restart and repeat from step 1.
Hope this helps you guys, and please if someone has similar issues - please let us know
