Phenom 955 and OCZ 1600MHz DDR3
operating system:
Windows XPI bought this board because I intend to use all 10 SATA ports for hard disks. When the mobo arrived a couple of weeks ago (end of June 2009) it came with BIOS version F4. It booted perfectly with a 955 3.2GHz Phenom X4 CPU and 2 x 2GB of OCZ PC3-12800 (1600MHz 1.9V) DDR3 RAM. The F4 BIOS indicated only 0.850V for the CPU instead of 1.35V, but everything else looked OK.
When I upgraded to the F5 BIOS, the CPU voltage was indictated correctly at 1.35V. However, the mobo was far less stable with the CPU Clock Ratio increased above x16, until I set the memory back to Un-Ganged (Dual mode). It now run stable for 12 hour periods with Prime95 at 54 deg C with CPU Clock x18 (3600MHz), Northbridge Clock x13 (2600MHz), HT Clock x10 (2000MHz), Memory Clock x6.66 (1333MHz) with 7-7-7-24-27-2T timings, plus a few of tweaks to increase the numerous voltage rails. I'm running XP Pro 32-bit on a pair of Samsung 750GB in RAID 0 (for speed), but will move to a 64-bit OS soon. Important data will be stored on a RAID5 array.
After a fortnight of tweaking I'm pleased with this board, apart from the times when it fails to detect the Performance (RAID 0) array on Channel 4 and tries to boot from a third drive on Channel 0, with no OS. It's necessary to switch off the machine and restart several times, before the BIOS finds the Performance array. By this time, the boot order of drives may have to be reset, to boot from the Performance array.
I tested the RAM at 1600MHz with the old F4 BIOS, but I've decided to stick with 1333MHz and tighter timings. Some people posting on the www.ocztechnologyforum.com site have not even managed to get their 955s to POST on this mobo, with OCZ RAM and BIOS F3 (2 versions) released earlier this year. There's loads of useful info on this and other sites for this mobo. I suspect that Gigabyte will be releasing more BIOS updates later on this year, to improve stability.
I do NOT recommend using the 1.44MB bootable floppy disk option to update the BIOS. The flash utility (executable) wipes any floppy inserted in the drive, which is very disconcerting. I finally succeeded using the flash option built into the BIOS, to save the old F4 BIOS to floppy and then load the new F5 BIOS.
I hope this proves useful to anyone else buying this board.
Overclock Voltages & Frequencies
operating system:
Windows XPSince my first review seems to have been reasonably popular, I thought I'd add some information on the overclock settings which I've found to be stable, when running Prime 95 for 12 hours. If you aren't using the same OCZ 1600MHz RAM (which I'm running at 1333MHz & 1.8V), do not increase the RAM voltage unless it's safe to do so. The CPU Voltage Control has a major influence on heat output, e.g. when I tried +0.100V the PC crashed in Prime 95 at 60 degrees (core temp), with a very large air cooler, so I set it back to +0.050V. If you find any errors in these settings, please feel free to make corrections. Enjoy.
CPU Clock Ratio = x18.5 (3700MHz)
CPU Northbridge Freq. = x13 (2600MHz)
CPU Host Clock Control = Auto
CPU Frequency (MHz) = 200
PCIE Clock (MHz) = Auto (2000MHz)
HT Link Width = Auto
HT Link Frequency = Auto
Set Memory Clock = x6.66 (1333MHz)
DRAM Configuration = Press Enter
System Voltage Optimisation
System Voltage Control = Manual
DDR3 Voltage Control = +0.200V (1.8V) TAKE CARE!!
SB/HT Voltage Control = Normal
NB/PCIe/PLL Voltage Control = Normal
CPU PLL Voltage Control = Normal (2.5V)
DDR VTT Voltage Control = Normal (0.8V)
NB Voltage Control = 1.200V
CPU NB VID Control = +0.250V
CPU Voltage Control = +0.050V
Normal CPU Vcore = 1.350V
Query
Can anyone say what bios version this is shipped with. Thanks
Hassle free
operating system:
Windows XPHad this board for a week now and so far, no problems. Couldnt get the HDD light to work with my SATA2 drive, but after discovering that I had plugged the drive into the wrong SATA port, the issue was soon rectified.
I used 4BG of Kingston HyperX 1600 memory (2x 2GB DC) for this build. The board defaulted the speed to 1333mhz, but after after adjusting the speed in the BIOS to 1600mhz, Gygabytes intelligent tweaker BIOS feature automatically altered the voltage and timings etc and so had been running like a dream at 1600mhz. I havent pushed past this as I have no need to at the moment.
I am using the Phenom II dual core 550 Black Edition processor in this and it seriously flies. I am running at stock speeds and its lightening quick. I may try to unluck the other two cores in the future, but I have no need to at the moment.
Overall, the board was simple to install, the BIOS very user friendly, everything works as it should and I am happy to say that my migration from ASUS to Gigabyte has been a hassle free experience.
5 stars from me.
My setup:
Gigabyte GA-MA790FXT-UD5P
AMD Phenom II Dual Core 550 BE
4GB Kingston HyperX DDR3 1600 RAM
Zotac 8800GT 512MB
