GA-E7AUM overclock FSB question

Here are my specs:
Intel Pentium
E5200 2.5GHz (200MHZ * 12.5) (800MHz FSB)
Gigabyte GA-E7AUM-DS2H F3a
G.Skill DDR2 800 Ram (2x1GB)
Windows XP SP3
Antec Trio Power 430 PSU
Latest version of BIOS


I def am a noob, but let me ask this question as best as I can.......

I was told that setting the FSB to 'unlinked' (in the M.I.T. portion of BIOS)
and increasing the FSB in small increments (5 or 10Mhz) was an easy way of overclocking.

I am getting blue screens.......................................occurs upon reboot when Windows is loading.



Can anyone point me in a direction as to why I would be getting blue screens upon very modest incremental increases?

I have run a couple of memory tests and my RAM seems fine, never a problem..

Hi

Do you have your mem voltage & timing set to manufactures specs? I have an ASUS board but see if your bios has similar features which can be disabled for overclocking. Also, make sure your multiplier is properly set. Obtaining stability may also require raising your NB, SB, and other voltages. Have you tried Linked/Synced mode, not as good as being unlinked but might be a good place to start.

I'll be honest with you, overclocking is kind of a personal thing between you and your board........Trial and error only you can resolve.

Also see what MaDMagik posted:

Yeah, everything is set to factory spec except I disabled most or all of the other stuff you listed......

basically, everytime I go into bios and unlink the fsb and memory, then raise the fsb freq even by a little tiny bit...i get a blue screen.

honestly though, I just experimented with lowering the ram freq( to minimum value 400Mhz), and doing so allowed me to raise the fsb by 15Mhz (to 815 Mhz) with no blue screen.

On another level, when you said that overclocking is a personal thing, I think I catch your drift on that comment, because there are many many variables.....
I will consult a local know it all I think

See, you already learned something important. Very few are able to run the ram at rated max with an OC, sometimes underclocking is necessary to maintain stability, good job!
