Can you give a link please

Phenom and High Ram Voltages above 2.2, I said 2.2V+. 2.25 is a risk due to the current difference generated. Heatsinks may not be able to help except the the CO2 Pipe!

Even without the Rebate!! That is an awsome deal!!!
Is that Canadian Money? That might be alot in American dollars no days!!

[Daveburt714]

Do I have a POS (Piece Of *****) processor? Your thoughts? Anyone?

Thanks, Dave.

I don't think so Dave, the phenoms need alot of tweaking! Kinda like a sports car....

Have you tried this thread? I'ts pretty deep in the begining, but if you read the whole thread it will start to make sense..

Might help!! Seriously!!

Bama is right about high Mem voltages!! But I think if you read down in that thread Tony says raising the NB/CPU V's will strenghten the diodes and allow you to raise MemV's to some extent.... He does have a BIG DISCLAIMER (Mine is 2x that! ) .... READ THE THREAD BEFORE YOU DO ANYTHING STUPID!! Just a polite warning....

Read that thread Bama sent you too!! Lots of good info there!

There aren't alot of Phenom owners here, join a thread and let us know your progress!!

BTW, I'm getting a ECS AM770 board to play with while I wait for GA to replace my 790FX. I'll open a thread on ECS if no one else has at that time and show results there for the ECS and Phenom 9500. I'll miss that 790FX board that is a dream board to say the least. If the ECS is good enough, I may just save the 790 for a newer Phenom B3 or later.

I would also like to see what Foxconn has to offer, they have been impressing me with thier intel mobos.

Same here.

I have have two little problems with this board.

1. My RAM (2x 2GB GEIL Value) is not stable when the ganged-mode is enabled. When it is set to unganged the system is stable.

2. I cannot move the mouse cursor when I have powered on shortly after I switched on the multiple socket. Sometimes I get a BSOD while booting Windows. Debugging shows that it is a problem with the USB-ports. When I replug the mouse it works fine. USB legacy support for mouse and keyboard is enabled in the BIOS.


Specs:
Phenom 9500
GA-MA790FX-DS5 with BIOS F3
2x 2GB Ram
HD3870
WinVista x64


A solution for the first problem is not that important for me but the second problem is really annoying.

I found Geil value ram to be unstable on all 790fx boards!

Have you tried different memory timings? Be sure to hit CTRL+F1 when you get to the BIOS main screen to enable all the advanced features, especially for memory timings.

[MorLipf]

With SPD-Timings the modules run fine on unganged mode. I have to test ganged tomorrow but I think unganged should be fine. It is a bit faster for modern applications.

A solution for the second problem is more important for me. I hope a BIOS-update will fix it.

I talked about this on OCF with my Phenom thread. The only way to really benefit from unganged is mostly on servers where more than one app is working hard to accomplish tasks. A single game app is unlikely to gain any from unganged.

I experienced improved gaming performance in ganged mode. MorLipf, have you got the latest F3 bios from Gigabyte for the DS5???

Also, on a further note, please pay attention to the fact that if you run in GANGED mode your are running in classic DUAL CHANNEL that those Modules were tested to run at.

Try the BIOS update, and check on the earlier pages of this thread, about what colored slots to run your memory in. I can only run in dual channel with both my sticks in Yellow or Orange. Not mis-matched.

[MorLipf]

Yes, F3 is already flashed. I have tried "ganged" for a second time several minutes ago. The result was a freeze in the CPU test of 3DMark06. My system is not overclocked and RAM runs at GEIL-specifications. GoldMemory and Memtest86+ have not found errors. Can it be a simple BIOS-problem?

Did you try both DRAM sticks in the Yellow slots? Also, make sure you are running in COmmand Rate 2.

Make sure you press CTRL+F1 in BIOS and in the Tweaking menu set your FSB and your Northbridge multipliers to 6 or 7.

Then try ganged mode. Also, make sure Cool N Quet is disabled in Advanced settings menu.

[MorLipf]

Both RAMs are in the yellow slots and the CR is set to 2. I think the BIOS settings should be ok.

@bro20000
What problems did you have with GEIL-RAMs? Memtest errors? My modules seem to be free of errors. Memtest and Goldmemory finish successfully.

Sent in my processor to New Egg under my 30 day warranty...got my new one. I was able to overclock it right away without problems, I did have bad core...if you can't increase the FSB to at least 215, one of your cores is most likely bad.

So my processor, indeed, was a Piece of S***
