Asus M3A78-T, 790GX & Phenom 9950 Review & Overclocking - PAGE 1
William Henning - Tuesday, September 16th, 2008 Like ShareEver since the AMD 790GX chipset launched, I wanted to get my hands on a nice 790GX board. The new feature set greatly interested me; especially the inclusion of side port memory for the IGP and Hybrid CrossFireX, and the potential for improved overclocking.
You may well ask why I was so interested - it's rather simple. Beyond those features above, I am a home theatre enthusiast, and the 790GX chipset seems to be perfect for HTPC's.
And as you may have noticed in my past articles, I am also into overclocking - and as I had previously been dissapointed in the overclocking headroom of Phenom processors, I was greatly looking forward to seeing if the "Advanced Clock Calibration" found in the 790GX would help.
The Asus M3A78-T (why on earth did they not call it an M3A79?) arrived in a shiny box that proclaimed all the wonderful features of the 790GX chipset.
There was more detail on the back.
In order to save your eye sight, here are the specifications for the board, taken from the Asus web site:

next: Recap: The 790GX chipset »
That does look like a good home theater PC board, I just wish I had the time and money to set one up my self. I havnt been keeping up with ATI's line of video cards, so I'm not exactly sure about how good or bad the onboard video is, but I think you would want to have a decent dedicated graphics card, like an 8600, to play full 1080i on a TV with out lagging everything else.
I was wondering, what program did u use to overclock the hd3300 igp on the 790gx board? ive tried rivatuner, but it doesnt show anything for me to overclock when i click on customize, there is no overdrive feature on ati catalyst(prob cuz its an igp) and ive also tried atitraytools, only to find that after i install and open it for the first time, my comp freezes. did u use another software/change in the bios or did u have luck with the programs i already tried?
