Total misery with my o/c :(

int · 5 Jun 2008 at 21:22

PC as in my sig.

I had this one stable at 3.6 (400*9) on stock volts (1.225), ram timings to 4-4-4-13 @ 1:1 (800mhz) and auto volts (which I believe is 2.0v).

I've knocked the cmos switch whilst refitting some fans, but I knew the settings etc so I just jumped right back up to those settings.
It won't post. I took the ram timings up a bit (it didn't post before when I'd pushed them further), to 5-5-5-15. With this, it posts & boots, but BSODS under load.

Whack the ram back to "auto" which I believe is 6-6-6-18 on this board. Not stable with orthos at all (1-10 seconds). I've put everything back to default now and it's orthos stable, but it's doing my nut in that I had a nice o/c and now I've got diddly squat and I have no idea what's going on!

Start from the beginning again, Taking slow steps till you reach your target.

Are ALL your voltages set to the same as before?

The only voltages I touched were the ram and cpu, both back up to what I had them at before and it's still not posting

I would up the other voltages too. I can't achieve a decent overclock without doing so. As long as you don't push them too high it's virtually risk-free so why not give it a go.

Which ones though? There are a plethora of voltages all with big a scary "AUTO" next to them and unfortunately the bios won't tell me what these autos are set at!

If your using 4 sticks of ram give the northbridge a few more volts

int · 6 Jun 2008 at 11:12

2*2gb

Pilky01 · 6 Jun 2008 at 11:14

whats the recommened voltage for your ram? Most motherboards give it 1.9v but you normally need 2.1

int · 6 Jun 2008 at 16:01

2.0 apparently, however the warranty covers 2.2+

good advice,.... ram votage 2.2.max

1kiwi · 6 Jun 2008 at 16:59

I assume you have you ram @ 2.1 +

It ran fine at 1.9-2.0 with the 4-4-4-15 timings @ 800Mhz which is apparently it's defaults. I'll knock the voltage up to 2.1 and see how things go

e: took it to the timings and voltage it can supposedly handle and I can't get it to post. put the voltage up to 2.1 (over the recommended 2.0) and it still won't post

e2: stable at 3.6Ghz (400*9) with 1.24V, 5-5-5-15 @ 800Mhz with 2.1V. Still don't know why it's not letting me go to 4-4-4-15 when they're the advertised timings!

What's the command rate set to?
1T or 2T?

Finally managed to get a nice stable 3.6 on stock volts (1.22V) with the correct ram timings too at 2.1V

When I have the time I'll try and push for a higher cpu clock as my load temperatures are currently under 50 so I think it can take some more beating
