What type of cpus are you running?

[KSC]

Thats a bummer. What mobo are you running? I'm getting ready to build an i7 in a couple of weeks. I recently started using Nebula and it beats the ever living snot out of my system.

Ya a lot of wasted time chasing that thing up on 6 occasions between my post and sorting office.

I've got the Asus P5KC.

A little tip on Nebula, took me a while to realize this but you're supposed to be using the Reverb version for everything, even eqs. You can edit the XML file to lower the latency from 8192 to something smaller like 2048. That goes from about 7% usage down to around 1% or so. Plus it's more stable with less dropouts/clicks and overall quality is supposed to be a bit better. I tried their Cuda bridge implementation but after using the Reverb version it doesn't even seem necessary now.

Thanks for the tip, very good to know. I'm trying to wrap myself around but every thread I've read has so many freaking pages. All the good info is usually hidden somewhere in the bottom w/ tons of useless post on top.

New order arrived yesterday. Got it installed and immediately tried putting in some settings I'd seen on a forum to reach 3350. Didn't like that too much and was getting lock ups as well as noticing the temp of one of the cores nearing 68c or so.

Reset things back to default and was a little disappointed in only seeing about a 10-15% increase in my test load project I made in Cubase.

Last nite started playing with settings again this time a little more smartly but slowly increasing and testing. My VID is 1.325 btw.

Got a bit of overclock last nite but heat seemed to be an issue, idling around 48c or so which didn't seem to leave much room for full loads. Have only got a stock heatsink though so probably can't expect too much.

This morning noted with the lower ambient temp of the studio (no a/c here so gets a little hot at the end of they day with gear running) things were looking a little better at about 35c with a cold system. That soon got up to 40 or so. I had actually lowered the voltage last nite to see if that helped with the heat.

At the moment though I've got it up to 3000 using 1.40v. Idle/light sufing temps are about 39-45c. With a 35% load project it reaches around 53c average. And with a 66% a few c higher.

Have noticed that in SX3 I can reload the project a few times and get fairly large difference in distribution. On my e6750 this project took about 95%. Sometimes when I've loaded it today it was still at that usage. But then I've been able to get it to 80% and even down to almost 70%.

Going to run it like this for a bit and see how stable it is and how much more voltage I need. Will probably aim for upper 65c or so as the upper limit of temps that I'd like to hit.

Are you using all 4 slots of ram on the mobo? I was only able to obtain 3.4 w/ 4gb of ram at an acceptable voltage. Just too much strain on the NB. Xigmatek, Prolimatech or ThermalRight are awesome heatsinks if your thinking of picking up aftermarket. Also what are you using to stress test? I prefer Intel burn test. It's quick and easy. 20 passes is all you need instead of burning in for 24 hours w/ prime.

Running 8 cores 2.66 Ghz. Live has not even breached 30% yet. Sweet.

Only using 3 slots. Haven't done a proper stress test yet just real world. Once I load up Cubase and get a decent size project going it was previously rebooting until I came to the current settings.

Highest temp at 3000 is 60c so will see how much higher I can get to 65. Also other than core voltage what else should I be looking at to increase stability. There's also PLL, FSB Term, and Northbridge voltages as well as memory timings but I haven't changed those yet.

When I had a PC I put an aftermarket Zalman fan on the CPU which by design also cooled the Northbridge IC. You rocking anything like that?

FSBT you really shouldn't have to touch. It's helpful in high FSB overclocking. Cpu PLL on the other hand can help stabilize an overclock. I would'nt go over 1.6v for daily usage, it'll start to degrade the CPU faster. If you have 800mhz sticks I would try to get 4-4-4-12 2.1v if it isn't already there, anything after 1000mhz usually timings will go up to 5-5-5-15. I usually oc one component at a time so if someting fails I know it's what I'm ocing. Underclock ram and oc Cpu and vice versa.

Ok will have a play with those settings then. I'm still getting reboots now and then not sure if it's temp related or just instability. Highest temps have been 65 so should be ok.
