Gigabyte is cryptic on some models, but we can derive by combining from what we know externally, that "Precise digital CPU power design" means an IR digital controller.

Those are probably only the SOCs, the UD5H, the UD7 TH and the Gaming G1. Ironically, the Gaming G1 doesn't have it on the description but it's probably the beefiest.

Conflicting review on the Gigabyte Z97X-G1 Gaming WIFI. This one reports it's on IR3563B rather than IR3580 of the other review. They are either both right, someone is wrong, or the BK model differs.

Can anyone make the chip?


Wait, he probably did dun goofed, because that does look more like a 3580 than a IR3563B.

BTW, how a IR3563B looks like,

ASUS Sabertooth Z97 runs an ASP1257 controller that the reviewer also has no idea what it hides (IR?), 8 phases, IR3535 driver, 4030DLA/6030DLB MOSFETs. PS. He claims most of the devices are at the same place they were previously.

I added "/Per Power Dissipation" for MOSFET Amps because it's considered good to have your Amps without having to go huge on Power loss/cooling in order to do so.

e.g. IR3553 40A/10.5W easy, CSD87350Q5D 40A/6.5W easier, PH6030AL/PH4030AL 79A/55W, 100A/69W not as easy.




no bump table update: ISL6388 reported to be on the MSI Z97 GAMING 7 http://pclab.pl/news57516.html

The quest for finding out what the heck is ASUS doing with renaming IR chips:

The old ASP1251 that was reported by a few sources to be really an IR3563A, next to a IR3563A:



The ASP1252 that I suspected it's an IR3563B:



Error. It's 10 vs 12 pins. It's not the same.

What about the ASP1257?



An IR3580 perhaps?



Or an IR3563B?

What are the alternatives?

An ISL6388 perhaps that MSI got?



Aha, 10 pins.

That might might mean the 1252 is actually an ISL. With the 1257 maybe being an IR 3563B or 3580

What does the ISL6379 used on Asrocks look like?



Bummer. It's 12 pin. ASP1257 chip can be that.

Alternatives to IR for digital controllers don't appear easily. The CHL8328 from older boards is 14 pin so it's out of the question.

But we derived:

IR Controllers are 12 pin so ASP1252 is not an IR. What ASP1252 or ASP1257 actually are is probably inconclusive with the information at hand.


note: The ISL controllers tend to be on 6 or 6x2 phase cards so they might be restricted to that. Hard to google their specs. I may continue tomorrow.

We've hit a potential Diamond in terms of low cost over high quality in an Asrock news thread. The Z97M OC Formula has the potential to have an IR 8 phase controller on the most advanced MOSFETs in the business, the 40A over 6.5W dissipation ones from Texas Instruments that are better even that the SOC Force's of GB because of their different dissipation stats. The board's info is not confirmed so I'll just put it with question marks based on the official marketing.

They already used that IT Nexfet in Z87 Formula and also used in Asus Rog mobos Z87/97, and for the PWM i am sure that its a ISL but can be wrong hard to tell from the photos i seen.

Correct on the Z87 MOSFETs. Sin's list is a great source for this. The controller of the Z87 was an IR according to his list, and it's my main source of the suspicion, though of course it's not confirmed.

edit: Important clarification: the list was on the EATX.
