My System Specs

Default amd 9950 @3 gig

Well finally got too 3 gig tonight been changing up hardware last couple weeks and seems was my cpu all this time that was holding me back, grabbed a 9950 tonight am at 15 times after a few reboots and tweak the voltage a little on this new core. Realize is not that big a deal but have never been this fast on amd before so am pretty impressed...

Running an Asus M3a79-t and 4 gig of Mushkin 1066 mem and a couple of 3870's in crossfire.

For some reason I have pump vcore up to 1.55v when I start going over 3.0GHz, whlie I see other people only need 1.35v for 3.0-3.3 range and 1.45v over 3.3.
So I'm starting to suspect it has something do with my PSU

When I first started playing all I did was bump up the vcore
Set DDR voltage and mem speed
Then I just keep bumping up the multi, made to 17.5x

When you start playing with the ref. clock, NB mutli and HTT multi then you have to start bring up the other voltages.

Have fun

I'm running a 125W 9950 with 1.35Vcore @ 3.2Ghz rock solid on the setup in my sig. I want to go for 3.4 Ghz but not until I get some slightly better cooling. I ran Prime95 tonight for 35 minutes and the cores topped out at 58oC. The cooler I'm running right now is an AC Freezer Pro 64. I have a Gigabyte G-Power to try out tomorrow. If it works out I might trade it for the Ultra-120 Extreme I have (couldn't use it because of mounting issues and air flow config :( ). Anyway, with its fan directed at the motherboard it'll be great for cooling the mosfets which are known to go up in smoke with this mobo! I have some ram sinks stuck to them right now and I'm hoping I NEVER have that problem arise.

Well I have a pretty decent sink it is the infinity Scythe, the cpu toped out @63c after prime was running most of the night, voltage I have tried up to 1.35 last night with no luck on both (could get into windows but not stable @ 3.1) so ya was wondering what v-core others with this set up were running...Will hit it again after I get a tea in me and throw so more juice at it... A swiftech kit is the next thing to get am too lazzy to get the homemade shit out of the boxes and want something clean looking not all sprawled out under my desks so ;)

Your ps Frank is concidered to be one the best you can get or least used to be wayback when maybe pcp+c has changed a bit since going more mainstream not sure.

I got my 9950 at 3.314Ghz at around 1.440V just to keep it rock stable. My watercooling keeps the temp around 35C on average.

I can't seem to get it to hit 3.4 stable though. I have a funny feeling my Mushkin RAM is holding me back somewhere. I'll have to tweak it a little more.

I got my 9850 stable at 3.37GHz with 1.45v iirc.
I had to drop it back to 3GHz because after 1.4v the mosfet of my board start to whine and it's annoying.

I'm curious for the ones OCing the phenom... are you using the good ol bios or amd overdrive?

BTW Frank... 1.55v to go over 3GHz is far from normal... I tested for about a week my 9850 at the default 1.289v for 3GHz and it was nealry stable (1-2 crash per 24 hours).
Something is wrong somewhere if you have to have need that much vcore

For 1.55, I think I could OC it to 3.5GHz (and hear my mosfet dying)...
