Overclocking, my current results. - Page 4

LOL

Is it wrong that diskeeper has just kicked in to defragment the hard drive because the CPU is idle while I'm watching a movie in full screen glorious colour with spectacular 5.1 surround sound?

'cos it has

Meanwhile my old P4 box is struggling with broken-up sound and I have no idea why (CPU isn't far off idle there either). Sadly as it's a custom-designed system it can't be upgraded.

Yeah, beyond a certain point, it becomes meaningless. The small gains achieved do not justify the extra stress on the components.

I only overclock my rigs as far as they'll go on stock volts nowadays. My E6600 could do 3.4GHz stable with extra volts and I can get it to do a 1M Superpi run at 3.6GHz with silly volts and fiery temps. It will happily do 3.15GHz on stock volts which is more than fast enough - a 30+% overclock with little effort is good value for money in my book.

Still on stock volts.

Memory is at 890 now. I'll Orthos it overnight.

2.5x Multi on the memory then, same as me. Maybe that gives me a little incentive to try 333 or 334 (currently 320), though I think that's far enough for me.

Niiiice. Be interesting to see if that's stable.

Feek · 27-08-2007, 10:30

S'OK Stan, no need to get jealous or impressed - It failed Orthos 17 minutes into the run! I've gone back to the previous setting which is probably where I'll stay.

Stan_Lite · 27-08-2007, 11:16

Pity.

Mine was rock solid on stock volts up to 3.15 then it needed quite a bit more voltage after that - iirc, I couldn't get it stable anything above 3.15 with less than 1.45V, then it was stable to about 3.4. I needed 1.6V to get it to run superpi at 3.6 (only did this once to see how far I could push it). As I said before, I just run it at 3.15 on stock volts - that's plenty fast enough.

Hmmm, thinking about it and looking at cpu-z above, that's actually still undervoltage, the board is set on auto. I may manually set it and try again.

Mark · 27-08-2007, 14:06

Feek, It's not undervolting (unless you deliberately did that). Even if you set the voltage manually to 1.3250V in the BIOS, it'll still read wrong. Motherboard voltage sensors are cheap parts and don't have the resolution needed to give an accurate result.
