Stock VRM heatsink only applying pressure to the end most modules due to PCB warp as mentioned earlier.


Made a backplate with a heatsink to flatten out the pcb and apply even pressure to the modules. But the heatsink does an amazing job at pulling heat form the back of the pcb and dissipating it.




Tomorrow ill be modifying the panel for a filtered 92x14mm noctua fan. This is what blows on the rear heatsink and really dropped the VRM temps.

looks good, what you make the heatsink out of?

You must have more room in your case to run all that back there :-D. I retired my UD3 to my living room to be a steam streaming device/movie server (FX8320@ 1.5ghz and 0.8 volts). Yes I underclocked it and undervolted the cpu, as I don't need performance. It barely sips power from the wall now, which is a good thing because it runs 24/7.

I made it out of an old Xbox 360 heatsink lol. Yeah I have an next s340 and it has a nice amount of room.

The pwm fan controls are VERY disappointing for my board. I was so use to Asus and how entensive the controls were.

Also, I'm kinda having a bit of a hard time oc'ing my 8320E and I've read several guides and what not. Again, the oc'ing on Asus boards was a lot easier. mad.gif

You can just pop the multiplier up, no need for anything else. Do it one at a time until it doesn't boot, then add a little voltage. Takes maybe 10 min. I jumped straight to 4.0ghz considering that is the advertised turbo speed.
post #11587 of 12377
Note that there is a big difference between a STABLE OC and a booting OC. The reason you have had an easy time OC'ing to 4.0GHz is that most chips are programmed to be highly stable on their Turbo Speeds without adding Voltages like Vcore. Add the fact that Auto Voltages (since you havent touched anything 'cept the Multiplier) defaults to considerably high values when left as is.

You might be surprised that if you touch more settings in there, other than the clock multiplier, you can achieve higher OCs than 4.0 even without adding or relying to Auto Voltages. Your chip's VID for example, might even guarantee an extra 200-300MHz above turbo speeds. And will be in fact stay cooler than Auto Voltages producing excessive values.

Just to quote someone from another thread,

" AUTO and VOLTAGE are two words that must be banned when used together here in OCN "

Yes, they are that bad!
post #11588 of 12377
Esp with amd and asus. I am sure it is the same with other manufactures

Auto is just a setting. Predetermined. IE (just an example. I don't know what it defaults to) auto llc is just high llc. But that may change in different bios

Auto vcore is either your vid or 1.4 if turbo is enabled.

If you have. Vcore at auto and set it to 5GHz your vcore Does not increase

Cpu-z is showing fluctuating voltages from 1.188v-2.00v @ its base 3.20Ghz frequency. I'll mess around with it later and post my findings.
