The only settings I've changed are: x36 multi, 1.25 BCLK ratio, 1.25V vCore, and 50% vDroop.

Do you guys have recommendations for the other settings like PLL, PCH etc. . .those settings are all foreign to me.

Also, here is a pic of my CPU if you can read the batch number off. (not sure where to look for this. all i know is that it's a Malay chip)

You've got yourself there a L203 batch malay . Ive got one as well . Mine is a dog chip needing 1.51vcore for 5Gigahurtles mad.gif I use a costarica which needs 1.48vcore for 5Gigahurtles smile.gif

Oh that's unfortunate frown.gif

I'm not looking for a 5GHz overclock though. A simple 4.6-4.7 GHz 24/7 OC is all need. So far, the chip seems to scale decently at the lower clocks. I only needed 1.25V to achieve 4.5GHz, so that looks promising for now.

The 30mV offset from my previous 4.3GHz OC did increase my temperatures a whopping 7C though.

eek.gif bummer ^^^^^^^^^

Increases in core speed will increase temps too, in addition to the extra vcore added.

What cooling are you using?

Oh snap! One of my P95 workers stopped after 12 hours and 53 minutes with "-1 errors, 0 warnings"

I assume this means I failed?

Just a wimpy H70 CORE. I won't be able to hit the higher overclocks without the temps getting out of control.

Try a 128-131 BCLK and lower multi, this enabled me to get stable with less vcore and reduced PLL to 1.65v. Something I picked up from another forum. smile.gif

What is PPD with this CPU. Thinking of upgrading my i7-920

Okay its a tad quiet here.......
Flashed my bios on Friday from 2105 to 3602 Run 5016@2400@1.485vcore P95'd 3 and a bit hours
wheee.gif
Temps between 52c - 63c thumb.gif I put the vcore up 0.005 and secondary volts up a bit . NO ERRORS thumb.gif
I probably didn't need to up the volts a little but she's stable and that's the main thing smile.gif

Good morning all! I've been following this forum / thread for a while and thought I'd contribute. Here's what I am running after finishing my loop and conducting initial stability tests. Though I am running 4.75Ghz now, I was able to get 5ghz pretty easy with this chip, but have not validated stability at that speed. Here's where I'm at now (been running P95 Small FFTs for about 7 hours):

How's it look? I'm pretty new to x79 overclocking. Rig is listed below smile.gif

Edit: That screen shot is hard to read redface.gif its running at 1.448v full load, 125 BCLK * 38 multi (HT enabled). Core temps are 73, 68, 67, 73.

Don't worry. We can right-click the picture & open it in new tab. It will open the full size picture. tongue.gif
