Bulldozer Tweaks

post #1 of 26
Thread Starter 
Let's share what tweaks we have tried and how they affected performance so others can benefit from and perhaps improve on our findings. For me, enabling one core per module increases performance a bit.

Just curious, but have you checked to see if you can overclock much higher with only one core per module enabled?

Hey cp whats up? Does disabling one core per module basically make it a 4100? OOps realized you are still left with 4 modules so no "sharing" of anything this way so actually better than a 4100. Interesting if they released a 4 module 4 core cpu with a 4.2ghz stock clock with turbo to say 4.9ghz or so. Now that for $150 would be a great cpu no?

I have tried, but I'm thermally limited right now. I can post at higher clocks but that's about it lol. Maybe it would be different if I could find my old water cooling setup

Interesting. I would have thought disabling one core per module would have lowered the temps and given you a little more headroom.

I believe that's going to be the 4170 (except 2 modules), but not 100% sure. I do believe updating the thread scheduler will make a good difference in per core performance. I have talked with a couple of people that are working on their own version of a thread scheduling optimizing program for BD architecture.It will be interesting to see how that turns out.

The temps are lower, just not enough to where I'm comfortable with pumping the voltage needed to stabilize it. The jump in voltage that I need nullifies the lower temps that were gained by disabling the extra cores..

u need to bump this thread tomorrow when it isnt so late. Im ready for the bashing. I gotta couple of comebacks up my sleeve unless Balla finds his way in here than I dont got any answers anymore...You should Lap your 8120 all the way to 2000 grit sand paper. mirror finish and practicaly dont need thermal grease. I got my PII 840 lapped to 1000 and dropped temps roughly 4-5C. I am really not a strong believer in it on new hardware but my lil phenom I was like what the hell? if you fry it u can atleast use it as a mirror, or a christmas ornament.

Found it likes nb around 2500 and ht around 2750.
Also found setting my ram as 2t instead of 1t let me get 155mhz more out of it with the same volts, Its not the ram getting limited ether since I tried lowering its multi more.
APM loses you lots of performance.
Running as 4M/4T gets steam games to run better but makes bf3 run worse.

I'm still working with my 8120, just don't have allot of time right now to tinker with it.
Wonder how long this thread will go before the OCN AMD hater's club shows up?
