Asus, Gigabyte, ECS, Foxconn, AsRock, & Biostar all have LLC.

It's not a new invention. It just depends on the Board/BIOS if they include it or not.

Added my Foxcon Destroyer to the GoogleDocs list.... could not find much info on it. :/

DOES have 8-phase though....8+1 or 8+2 though, is anyone's guess. :/

It's only 4+1, but it can handle 140w TDP chips without fail

Actually, the ASUS LLC has a drawback - it causes voltage flugtuations.

Any of you kind people mind shedding some light into this for me at all?

Took a snap of my Mobo, the NIKOS are just above the Southbridge, the others that I have no idea what company are from, are just above the MOSFET cooler in the VRM, I'm assuming these are the ones for the RAM?

Now I'm pretty sure in my research, have seen these same Transistors under the MOSFET heatsink on either my Mobo, or a similar one that Reflex said was similar (NF980?).
I've also heard of MSI using NIKOS on unimportant area's and other ones for the important area's.
I have Version 1.2 of the Mobo, and I was hoping that meant something, Tator previously stated his one ran NIKOS, but I wanted to dig a little. tongue.gif

I'd take off the heatsink and check first-hand, but I dunno what to replace the thermal strip with. :S
(any pointers to that would be appreciated)

NIKOS can be fine when used on unimportant areas. On many of the lower-end boards (i.e. anything that is not DrMOS) NIKOS is used on the CPU VRMs, this is very dangerous.
I think if it's a thermal pad connecting the VRM heatsink, it can be reused. Might want to clarify at Air Cooling forums though.

Circumstances forced me to go inactive back in 2014. I guess I'm back for 2016, but won't be active much! Cheers!

Do you know who (ON) are? I can't seem to find any information on them or specs.
I know I won't know for certain what MOSFET's supplying the CPU power are until I remove the HS, but I've seen this same (ON) MOSFET layout under the VRM HS when I was trying to find out more about my board, I didn't bookmark the page for some reason, but someone had stripped the HS and it had these all there, can't confirm if it was my Mobo or one that was sharing the same layout.

Seeing as they're used in the +1 phase, would it be safe to assume they could possibly be supplying the CPU power aswell?
I've only read of ON being used a Driver MOSFET here: -http://www.overclock.net/amd-motherboards/959289-cpu-vrm-mosfets-transistor-discussion.html (7th paragraph down).

I'm slowly trying to learn more about MOSFET's, as it's intrigues me greatly, and they are an extremely important part of the system, by all accounts.
You'll have to forgive my ignorance, I'm trying to find out more. tongue.gif

Thanks for the reply so far. smile.gif

EDIT:- Okay, when I Googled "ON Semiconductor", I didn't get anything apart from things with "on" in it, lol. Just found them via datasheetcatalog.net, (previous searches for top semiconductor companies didn't go well finding this one, lol)

The only numbers on the MOSFET's are 933, 48 and 0ENG or OENG. Trying to find out more, but I don't really seem to be getting anywhere with what's imprinted.

That "+1" phase supplies the power to the integrated memory controller, not the CPU.

I think "(ON)" mosfets simply refer to the traditional type of MOSFET chip and transistor supply/clean design, i.e. (ON) MOSFETs as contrasted to Driver MOSFETs. I'm not entirely sure though.

Yeah I wasn't ever sure if the "+" phases supplied power to the IMC itself or if it went to the DIMM's in some stupidly long way, seems I read something that threw me off the IMC for some reason, thanks for clearing that up.

I saw something about RDS(on) chips tonight aswell, and the different types of MOSFETs (much more to it than I realised).
I can't find any part numbers within ON Semiconductors listings that correlate to the ones in the left picture. Flipping it upside-down, I seem to make "09NQ" possibly, but I'm closing in on a huge wall of tired right now.
