My Crucial M225 2.5-inch SSD is starting to fail me after 3 years of use. So I'm going to RMA it. They will supply me with a SATA III SSD drive. Will it work without any issues on this board?
Have read that some boards can lose the TRIM support.

Is AHCI mode going to work?
Quote:
Since AHCI was created by Intel, this functionality is used by their chipsets only and computers that do not use the Intel chipset are unable to use AHCI, unlike RAID which has been pretty standardized and can be obtained and used by a wide variety of manufacturers.

I just set E-SATA controller to AHCI, and should I set the RAID MODE to AHCI?

I don't know in detail, But AHCI provide 'Hot Swapping' and Trim for SSD. And it works with AMD too, yeah it is true its of intel. Your Sata III SSD will work on GD70, but performance will be limited to Sata II bandwidth. Actually trim works with windows 7 only when AHCI is enabled. I had this mobo and had been running 2x Hdd in RAID 0 with no problem, but I never used AHCI. There is a latest AMD AHCI drive (12.2) in Amd.com. Your SSD will not be detected in AHCI Mode by windows 7 while installing windows 7. You will have to install this driver during installation of OS.

I reinstalled W7 in AHCI mode, and I can feel a huge improvement. My SSD was performing well in W7, but now it so smooth and fast.
For example installing software, turning of PC... much better performance.

Hello im new in forum but i have to mobo msi 790fx-gd70 in ver.1.1 and maybe have chance to not burn my mobo with x6 phenom oc ?

a good idea would be to get a small 80 mm fan and stick it on the south side of the vrm heat sink and with that blowing air you should be able to keep it chugging along. ive got a phenom x6 oced to 3.4 ghz and all is good so far

There is always a chance of death of 790FX GD70 with an overclocked 125watt X6 CPU even it is rev1.1 board because it has only 4 phase too. Let me tell you some important things related to 790FX gd70's Phase/VRM/MOSFETS as I have blown up three GD70. One of them was 890FXA GD70. Each phase can provide absolute maximum theoretical current of 40 Ampere (Mosfet name is = RENESAS R2J20406, you can search and download pdf). Maximum temp limit is 90c. It means 4 phase x 40 ampere = 160Ampere (max). Max value has never been safe for real world operations because at this peak point extreme heat occurs (close to 90c) which is very hard to cool. Remember as MOSFET temperature increases, the current carrying capacity of each phase reduces as well.

Now All Phenom II 125 watt CPU require 110 ampere current at factory clock (According to 'AMD's Power and Thermal data sheet', you can search and download pdf). This current requirement can easily be provided (At factory Clocks) from 4 phases because each phase will have to deliver only close to 28A, Which is safe for motherboard. But as you overclock CPU with increased voltage, current requirement of cpu also increases. It makes VRM to become more hot as current requirement of CPU goes close to maximum support of VRM.

Many Thanks, Sir smile.gif
I just want to help everyone that they must forget to overclock any 125watt X6 CPU with any 4+1 Phase MSI motherboard. I have lived in a nightmare for whole 1 year with MSI's 4 phase motherboard they all died while they were being tortured for only 15minutes of stability test in Prime95. A few people have overclocked very well because they managed a lot to cool VRM by adding custom water blocks to VRM , not every one can afford this method and it is also expensive .....After all we all know Its all about temperature who kills hardware !

my voltages were not changed and 400 mhz is a small push in frequency. this wouldnt be able to push the amps count much higher. ive also taken many precautions with this board. i have the vrms being cooled and cold air is being vented throughout the whole case. do appreciate the useful advice none the less. wish msi wasnt such a cheapout on their phases
