Hi

im running the following

e5200
gigabyte p45 DS3 patched to F9 latest bios
4gb OCZ Reaper pc6400

ive gone into bios and set it up to the following

12x multiplier

320 fsb

ram @ 5-5-5-18

mch +0.1v
cpu @ 1.316v
ram @ 2.1v

Save and exit, and pc reboots, then cycles a further 3 times before booting into vista, where coretemp, TAT and cpu-z tell me im running standard clock speed, standard clock voltage etc, but my ram is at the 5-5-5-18 setting i set it to. (was 4-4-4-15 on standard clock speed).

so restart, go into bios and its telling me im running at 3.6ghz.

So i dont know what speed im actually running at!?!!??!

done test before and after and still get the same 21 seconds in superpi so im inclined to believe the windows programs and not the bios. everything is turned off from speedstep to EIST.

help!!!

edit: it seems to reset my fsb when i reboot, as i just set it to x10 + 300fsb to get 3.0ghz, and its booted up at 200x10 giving me 2ghz when default is 2.5ghz, any reason why it wont let me change the fsb ???

disabled speedstep and c1e?

also try upping the voltage a bit for stability

it sounds to me like its a failed overclock thats defaulting on reboot. Try 300 fsb those e5200's don't like much higher than that...

i just tried 270fsb and it defaulted again

Speedstep and c1e etc are all disabled!

Ive done some testing and my FSB wont run over 200.

Even if i set it to 201, the pc reboots 3 times and resets the bios.

motherboard error ? shall i try downgrading to F8 ???

Could be you just got a bad batch of CPU's not everyone's overclocks the same, regardless if identical hardware is used.

it should run at 2600mhz surely ?

What have you set the RAM muliplier to. You need to slow down the RAM otherwise it will be speed up in ratio with the FSB resulting in a failed boot.

i set it so it looked like this in bios

800 800

decto · 26 Oct 2008 at 18:21

I don't think the P45 allows you to lock the RAM so when you increase the FSB by 10% you increase the Ram by 10%

Set the RAM to 533 800 or 800 533 whichever way around it is

many thanks ram running at 600 on mchB iirc and now have 3.6ghz.

i take it i can steadily increase the ram upto 800mhz to speed it up ?

Congrats....

The ram will be fine, you can speed it up a little should be good for 850/900 depending on a little luck. Now you have you CPU running ok you should see the effect of the memory ratio change as you select it in the BIOS.

Enjoy
