Bizarre 2600K Overclock Problem - Page 2

Now that has completely reversed, which I find truly bizarre. I'm hoping someone knows what the hell is going on. In the meantime, I'm leaving P95 out of my stability testing. At this point, I'm basically overclocking to temp if that makes any sense.

If I can pass Linx (the latest) 50 passes with max memory, and never hit 73C then that is my 24/7 OC.

I also test with lightwave3D, I've got an image that used to take 21m to render on my OC'ed I7-920 (4.3G), now it takes 15m. That render has also crashed when I wasn't stable, so I think as long as I can pass linx and lightwave without throttling, I'm good.
Yes the temp thing makes sense. I am at 68 max on 1.44v and I don't want to go much higher. The thing for me is I also tried OCCT 3.10 and that crashed too so I too am confused why IBT would pass so easily.

Could you try testing with LinX?

I could try LinX sometime. Right now, however, I am working on getting P95 stable unless I hear that there is a real problem with it. I am at 1.5 hours and it is still going. This is the thread ugotd8 was referring to and there is a link to LinX on that page so I assume that is the one I could try. Some are saying that they pass LinX but not P95 so I still want to pass P95.

P95 just failed again at 2 hours on 1.44v. So 1.45v (reads 1.416v in CPU-Z). This might be as high as I go. Next step I might try is what Sin recommends in his guide. See below.

Does anyone know where the TDP and TDC settings are?

"If not already using turbo options, please do so. Now set upper limit on TDP and TDC at 200-300 to removed TDP and TDC limitations. If your board has OCP (over current protection) you can disable this if you want a very high overclock."

Well, that will certainly stop any throttling going on. Wont help P95 in my experience. I've had those settings per sin's guide, and P95 still fails.

In testing last night I was able to do something very interesting by changing these values and using TMonitor to watch throttling. What I think I found is this, let's say I'm at 4.8Ghz and 1.4V at load. Now by default I was setting both power limits to 150 (per the screenshots of the wind guy that reviewed the TP67XE and posted it a million places).

Now with those settings, Linx and P95 or lightwave would never throttle.

Now, I *LOWERED* those settings to (trying to remember) TDP 120 and TDP 130 (BIOstar has 2 power limits 1 & 2, the TDC was 150).

Now Linx and lightwave would not throttle, but Prime 95 was throttling the cores at around 4500 !!!!!

So, needless to say, I was passing Prime95 now. Still Linx and lightwave stable.

The moral to this little story is, these people you see passing prime95 may be throttling during the run.

Update:

P95 still going for 2.5 hours now, 47X on 1.45v. But I wonder if I should adjust some of the other voltages before more Vcore. On this site they got the 2600K up to 4.8 on 1.35v but with these other voltages set.

Sin's guide recommends never touching VCCSa. The others look like they might help, I'm adjusting those up slowly now myself.

Yep just reviewing that and also this http://www.xtremesystems.org/forums/...d.php?t=264300

Looks like the only things that may help for me if following the above guides are to change Load Line Calibration to Level 2 and QPI (VCCIO) to 1.1-1.2.

I am still going to leave these alone (ie the ones Sin says don't touch) but here this person also adjusted the System Agent Voltage.

"Load-Line Calibration gets enabled, then plug in your voltages: a CPU VCore of 1.3V, a QPI/VTT (otherwise known as the VCCIO) of 1.12V, a System Agent Voltage (aka VCCSA) of 1.135V and a the usual 1.65V of DRAM Voltage. You can type these values in directly, but Gigabyte jumps between 0.01V and 0.02V increments on different settings, so you might need a bit of cursor-key fine-tuning."
