Good MoBo
- Pros: Small with lots of features. Excellent Bios options.
- Cons: Does not ship with Windows 7 Driver Disk
- Other Thoughts: Great mobo It unlocks the cores of the PhenomII 550 with ease. Great Bios options.
Great mobo
- Pros: Works great out of the box, windows 7 ultimate 64 installed and found all of the drivers.
Runs a AM3 socket AMD Athlon II X4 620 like a champ.
MAKE SURE TO UPDATE BIOS!!!
I've had a stable 2.9ghz over clock, but didn't keep it.
- Cons: I did notice like others that the VGA plug is flimsy, but I use a PCI-E card so meh.
- Other Thoughts: Make sure to google "asrock a790gmh/128 drivers" first link will land you on their support site to download all the drivers for the mobo ;)
Very good value
- Pros: On-board Radeon 3300 for everyday graphics and some games too, SB750 for improved throughput and RAID-5 (if you need it), small size for smaller cases, well thought-of low profile components around CPU that allows you to mount a huge heatsink, generous BIOS options unless you want to overclock, plenty of SATA ports and a reasonable price.
- Cons: Two problems I faced that average users might also encounter:
1. Neither of the Front USB connections could handle a WD Passport 320GB USB drive. The same connection works with a flash reader and SD or CompactFlash. This could be a problem in my USB dongle (wires/connectors/shielding, etc) or a lower power output from USB port itself.
2. Drivers shipped are not for Windows 7. You wont hear even a blip after loading Win 7 unless you go to Asrock web site and download the VIA audio driver! Win 7 has bundled Radeon 3300 driver that works fine -- unless you miss something.
The mobo itself has 2 problems (minor for average use):
1. DDR2 Slot-1 and 2 would not handle 1066 data rate -- only upto 800. You need to use slot-3/4 for 1066 rates.
2. The on-board 790GM northbridge needs heat pipe and fan! It gets hot fast.
- Other Thoughts: For OC... here are some useful but unsupported/imprecise BIOS options
- NB Voltagecontrol is there BUT ...which NB (the DRAM controller on CPU ?) or on mobo?
- CPU termination voltage adjustment
- SB750 voltage adjustment
I am able to bump up X3 720BE to 3.4 GHz with 1.4 Vcore and 1.3v NB, 2.14v GSkill 1066 and the system is rock stable under overnight-Prime 95. Needed to add 2 80mm fans with some thought to disperse the heat to make it Prime-stable. Max temp under Prime-95 was 52C at CPU and 53C at mobo. No-load temps are around 29-30C. Used only 3 cores -- never tried opening the 4th.
