What is Jmicron/ICH9R?

post #1 of 6
Thread Starter 
Hey guys,

I've been doing research for a mobo to buy with my new rig (early August). I plan on getting the G0 Q6600, have Crucial Ballistix Tracer PC2 8000, 2xSeagate Barracudas 7200.10, dvd burner (sata), dvd reader (ide).

People have been saying weird stuff about the P35 boards and this Jmicron controller and ICH9R which I have no idea what either are. Can someone please help me. I want the P35 chipset and run Raid 0. I would like to run the dvd burner with sata, is that recommended for best performance?

Thanks.
Paradise

ICH9R is the Southbridge chip on the p35. Jmicron is an additional raid controller on the board.

The problem (from what I understand) on the p35 boards is that the componets you don't have too much controll over (chipsets and bridges) have very tight timings. This gives you great performance at stock settings, but it won't allow you to OC your processor to high FSB's. Other boards that have looser timings on bridges and the like allow for very high OC's (500 FSB+) if you have the right cooling, but performance at stock will hurt a little bit.

Like I said, this is what I have read... Could just be specific to the P5W board, could be all a lie, but it sounds like legit reasoning.

It's best to just avoid the Jmicron controller.
Run all of your SATA drives off the ICH9R.

I had a p5w dh deluxe before this (my wife now uses that one) and the stubborn cpu in my sig had a REALLY tough time going over 3ghz. p5k changed all that. My experience: the board is GREAT!

Yep. Intel also has the Matrix storage RAID controller. YOu can choose between the two if you want to run RAID on a P35 motherboard.
I assume that you are looking at my motherboard.
