That stuff around the NB chip is like chewing gum! I've replaced that with some Ceramique and the pads on the VRMs with the stuff you get from EK with the GPU blocks.

Oh wow. I don't have Ceramique. Would any TIM be an improvement over this?

I'm wondering if this is why I can't get my chip past 3.8ghz when it did fine over 4ghz on my other board.

Yeah, I cleaned it all with some solvent cleaner. I could get the top of the NB really clean but had to leave most of what was around the outside of it becuse it's so sticky. Just like gum. Here it is ready for refitting of the heat sink;

I've no idea if it's any better tongue.gif, gonna try it tonight. biggrin.gif

Good going, man. Seeing those pictures helped me a lot, and alas: I don't think the 990FX UD7 waterblck would fit the Sabertooth. The NB chip is slightly in a different position. frown.gif

I don't think heat would trully bottleneck: I found the core of my notquite-stable problem, and it wasn't the V-core-1 temp. It looked stable at 1,428 V, and even if I upped the + overvolt, it'd remain at 1,428 so I figured my board thought that was enough.

Which partly is true: this is where Load Line Calibration comes into play.

Medium / high LLC seems to top off at 1,428 V with my Saberikitten, but Ultra high seemed to allow for 1,464, which was just what I needed to get my Saberkitten OCCT stable.

Regards and best of luck with the new tim / heatpads on the heatsink, Wolves! I can't wait tto hear the result.

No joy I'm afraid, well not with the VRM temps anyway. The change of thermal pads hasn't helped there. I think I have a lack of air flow over the heat sink so my next thing to try is a spot fan. I've got a 40mm fan knocking about, anyone got any thoughts on that? I've got a 60mm somewhere, not sure if I've got room for that though.

On the positive side, some AS5 on the CPU has knocked 5c off the core temps. Well, the stuff I used before must of been proper crap I guess.

I don't know what's going on with yours but mine is 1.488 with high LLC at the moment.

I will correct my question:
Does TurboV EVO let you set each core's multiplier with dozer/piledriver ? I can set each core's multiplier between 4x and 35x with a Thuban. 4x is pretty close to off.

Hey guys, cooling the VRMs definitely matters. But you do not need to use a water block. Check this out! I had the sabertooth and a 960T and I was able to drop the VRM and CPU temps quite a bit. I posted the results at overclockers.com same username so you know its me.

It is pretty much pointless pushing this 960t past 3990 on all 4 cores. This good for 24/7. I keep the VR module temps down with a old G-Skill memory cooler (2x60mm fans) bent to fit. I use a 6 pipe, 6mm single ended Scythe silent low profile cpu cooler. I did not get any better results with a corsair A70 I added a sunon (molex powered) 120mm set in updraft or pull, So much for silence. In the push or downdraft it added heat to the VR.
I will try this again when my 8350 gets here. The load was Boinc Milkyway@home and Mass Effect2 maxed @1920x1080

Hmm... I might just try and figure out a way to mount the Noiseblocker BlackSilentFan XR2 (the 60mm fan I got modded/mounted in the roof of my Arc Midi case, sucking air from the VRM block)... As of yet it doesn't make that much of a difference (Vcore-2 is cooler, 1 not so much), but it's surprisingly silent at 1700ish rpm.

I might try some magic with tiewraps first wink.gif

Thanks for the tip!
