The bottom of the PCB is also populated with plenty of connectors and headers:
-Front Panel Audio Header
-HDMI_SPDIF Header
-COM Port Header
-Floppy Connector
-Infrared Module Header
-Front Panel IEEE 1394 Header
-Consumer Infrared Module Header
-3x USB 2.0 Headers
-1x USB 3.0 Header
-Chassis Speaker Header
-System Panel Header
-Power LED Header
Close to the Dr. Debug LED display, we can find the Asmedia ASM1083 PCIe-PCI bridge:
Another EtronTech EJ168A USB 3.0 Controller is found in the bottom right corner of the PCB:
The PLX PEX8608 chip is used for providing additional PCI-E lanes:
Near the Power, Reset buttons and UEFI chip, we can find 4 SATA 2 and 4 SATA 3 ports:
Two of the mentioned SATA 3 ports are controlled by the Marvell 88SE9120 chip:
Close to the ATX 24-pin power connector, we can find the Clear CMOS jumper, and another chassis fan header:
All memory slots have now the same color, not different as we have seen on the P67 Extreme4:
Two CPU fan headers are located between the VRM heatsink and the memory slots, on the top side of the PCB:
If I may, when you guys are about to do a review on a product, can I suggest trying to do a little internet survey about potential problems BEFORE publishing your conclusions?
If you would have done that for the Extreme4 GEN3, you would have found very quickly a lot of forum posts about 2 major issues. I would like Asrock and/or you guys to comment about them:
1- Etron EJ168A USB 3.0 controller
Despite the fact this controller recently received the SuperSpeed USB Certification from the USB-IF, it is still plagued by problems such as random disconnect from external USB 3.0 hard drive. It also has issue with some web cam and other peripherals. Your USB device might work, or not. How would you like Russian roulette style USB connectivity with your brand new 185.00$ purchase?
Neither the latest 0.105 drivers or BIOS 1.10 from Asrock solved those problems. This is unacceptable for a brand new product. To Asrock defense, Gigabyte board with the same Etron controller have similar issues.
2- Integrated Intel video
Get this: If you use only the onboard video without a discrete card, the system reboot and/or crash randomly many time every day. According to Asrock tech support on those forums, the only current fix is to up de CPU voltage to 1.2V!!! This is an Asrock specific problem as I couldn’t find forum complaining about this from other vendors. Just Imagine someone not knowing about this major flaw and planning to use the Extem4 GEN3 with the onboard video only... Let the tech support / endless e-mail / multiple RMA begin…
