Ehh I'd have to take my rig apart and I'm pretty lazy. There is a hole in the board tray underneath the socket so it's possible I might be able to do that without taking anything apart. PSU might be in the way though. If I can do that I will.

That's also why I say I can touch the heatsink in the tests. It doesn't give a number but if I don't burn myself it must be low enough.

those posted images? FLIR? are trash to use as anything but "pretty colors" anyone using them to back up their point - instantly invalidates the point, but you knew that right?


the problem we are having - is that we have too many "armchair" engineers here - and we have people who have been doing this for more years than most of us combined; I wonder who is more correct?
I come here to have fun and share information, not have people call me names, swear at me, put me down and show off their e-peens just because they disagree.

For multiple pages now, I've been saying the same one thing. Of all the people who got involved in the conversation and had the hardware I mentioned, only one was willing to get the conversation going. The one who just posted above me.

Enough is enough already.

For starters the prime has just one fet per phase. The amperage capability posted is also wrong due to this.
Next is the doubling in phases taking place, doubled or not as long as you have coil, driver, high side fet and low side fet all connected to the pwm, with or without doubler, you have a phase. If you had analog (well, hybrid more likely nowadays) pwm instead of digital, you could have even more sophisticated setups with interleaving allowing something like 10 phases with 3 doublers using a 6 phase pwm or something. The point is that the numbers on that post are messed up.

I believe everything else is right other than the two fets per phase on the Prime. It has 6 straight phases (not doubled) but pretty sure the 240A is correct. This board seems to have similar amperage capabilities as the Titanium. It also doesn't have bclk option like the more expensive boards so it seems to be the best comparison.

Indeed, the 240 amperage on the prime was correct.

Just throwing this out there...

This is 890fx ud5.

Myself and mad22 were benching wprime 1024 for a comp...same board...we both popped the vrm on same board.

Now i could be wrong but this was a 6+4. (Cpu/Nb) iirc. Very similar to something we currently see on a certain board. Chips were thubans iirc.



This phase design 5-6 years later looks awful familiar...lol.

Why not compare your apples to my apples? - plop a fan on your VRM heatsinks and see what you get for VRM temps on an hour of prime 95 blend - even if you want to run stock clocks , I'd be interested in seeing those temps as well.

isn't the chips on the backside is the doubler?

Not for the CPU VCC, the two doublers on the backside are for the SoC VCC.
The rest of those ICs are drivers.
