How is this clock?

Got a new cooler today and I've got 3.4Ghz w/ 1.55V. If I try and run my RAM at its default settings (667Mhz) the computer will just die so I have to run it at 1:1 (533Mhz). That wouldn't make things slower, would it?

Also, I've tried getting to 3.5Ghz with the max volts (1.58) and Orthos just won't go past 2 minutes without crashing. Have I hit my wall? Also, the multiplier on my board can't be changed from 9, can that hold me back?

Thanks
 
The problem with running the memory at 667 when overclocked might be fixed by manually configuring the memory settings in the BIOS. As for your overclock I'd guess you've hit the maximum.

At 1.55v what are your core temps in CoreTemp 0.95.4 when running Orthos small-ffts?
 
They were at around 62c with small-ffts after about an hour.

I had some trouble though, my fault really. The RAM was running at 533 (1:1) 5-5-6-15 and I wanted it to run 5-5-5-15 so I did too much messing about and forgot the settings that worked. Is there any downside to running 533Mhz 5-5-6-15 compared with 667Mhz 5-5-5-15 at a lower CPU speed?

Now I've got:
3.1Ghz w/ 1.46V
667Mhz w/ 4-4-4-12

Temperatures don't get any higher than 52c like that.

If I wanted to go higher, would it be my RAM holding me back at this point?
 
It's more likely the MSI motherboard holding you back than the CPU/memory specifically the northbridge. Did you try raising the NB volts?

As for 533 vs 667 at close to the same memory settings I doubt there is that much in it maybe 5-10% difference in games.
 
Thanks, unfortunately I don't think I have the option to raise the NB voltage either, this board is pretty pap when it comes to overclocking :(.
 
That's a very good overclock on an E6600 on a P975 motherboard with air cooling and don't let anyone tell you otherwise. Most E6600's will only do 3.2-3.4GHz on air stable anyway, so it may not be the motherboard, but it is a very, very good overclock.
 
Thanks :).

I've got it back up to 3.4Ghz but I'm still a little concerned with the RAM.

Which is faster, 3.1Ghz 667Mhz 4-4-4-12 or 3.4Ghz 533Mhz 5-5-6-15?

Thanks again.

It is a good overclock. Though i think mine would probably go further is i had a btter board than my GA-965P-DS3. (Has a FSB hole around 370-400). Guess i must have been lucky with my 1.4V im putting to get my 425x8 OC.
 
id go for the faster ram and 3.1ghz cpu

though its quite strainge how the ram runs faster with the higher timing and lower cpu fsb i would have peged it to run better with higher cpu speed lower mem with tighter timings?

I would have as well, at least 3.4 w/ 533 @ 5-5-5-15.

So you'd scrap the extra 300Mhz on the CPU and go for faster RAM with better timings?
 
I read about memory speeds/timings recently and 3.1 GHz with 533 3-3-3-8 is marginally faster than 3.1 GHz with 667 4-4-4-12 because of the way the memory controller works with dividers etc.

The difference between 533 5-5-6-15 and 667 4-4-4-12 at the same CPU speed is about 0.5% in favour of the 667 4-4-4-12 which is pretty much no difference at all!

EDIT: Got it a bit wrong first time. :D

I read all about it here:

That sounds ok then, thanks for that. I've currently got 3.3Ghz 533 5-5-6-15, the RAM doesn't like the higher FSB, Orthos fails after 2 hours.
