Phenom OC
« on: May 02, 2008, 05:50:37 PM »

So, the other day I decided to see how far I could push my Phenom 9500 on stock cooling. Monday I bumped the mult from 11 to 11.5 giving me a 100mhz oc to 2.3ghz. Machine ran rock solid for the past week, so a few min ago I bumped it up to 12x putting me at 2.4ghz. Still running great, and I will be pushing the machine hard over the weekend to see how stable it  is and if I could push it to 12x giving me 2.5ghz

Overall, I am wondering if the HT bus speed difference (200mhz) between the phenom 9850 black and my 9500 going to make much of a performance difference seeing as they will have the same clock speed? If there will be a major difference, how much oc-ing can the HT bus take?

I finally decided to take the OC a bit further, and am now stress testing the cpu at 2.9Ghz. Hopefully it will make it to 3Ghz or higher. It just seems odd to me when I am able to bump the CPU 100mhz at a time and it takes it like a champ.

One change I did make was the move from stock cooling over to a Cooler Master Hyper 212 HSF and Antec Formula 5 compound (The guy at the store swore it was the same as AS5)

What's your HT Multiplier set to?

Well, the burn in at 2.9Ghz passed with flying colors, and the system posted and is currently testing at 3Ghz

I currently am running at a 200mhz FSB and a 15x multiplier

You could probably get more stability if you lowered it to 8x, and your HT bus multiplier to 3 or 4x.

IIRC from S939 days, the HT multiplier only went to x5; I'm guessing that's the CPU multiplier, or that's the Phenom Spinal Tap edition, although doesn't that one only go to x11?

I'm still getting used to these HT over clocking methods, I don't quite understand all the various multipliers and ratios and such. But  I am reading about it more and more.

I have manged to get the system running stable at 3.2Ghz now, using the default 200Mhz bus and a 16x multiplier. It does not seem to be getting that hot though, 74 idle, and a guess of the mid 80s full load (no temp sensors running in Linux yet)

if i'm understanding you correctly. 74c idle is not a good temp to be "idling" at.
