Can help better if you post your BIOS settings.

Here is the bios template... Copy it & paste it in this thread with your current settings... If setting is "AUTO" please post what auto setting is...

Also your complete specs of your machine including all hardware is necessary.

oh ya
i added two xms3 2gb sticks of ram
apevia warlock 750 power supply
intel core 2 duo
two nvidia geforce 8600 gt's

it think thats it

You need to fill out the template completely as to begin getting your rig stable,voltage's,fsb,mem,ect.

all i've tried with memory is takeing one out
to see if that improved the system and it had no apparant effect.
i have not tried running it on one video card
and for what do i need to grab the voltage on?
i looked again at the link she gave me and didn't find anything about voltage?
thank you for your patiance

Voltage's,mem timing's and so on.You will get alot more help when comepleted.You can copy the template,paste it in the quick reply box and type in your info.

Have you tested your system for stability by running Prime or IBT?  Run IBT for 20 passes max stress and keep a eye on your temps.  Use Everest Ultimate to monitor your temps (free or paid version).

This is the situation...we cannot assist you properly without a completed BIOS template..it is that simple.  Please read the following and follow it to the "T".  Now that you know how to find your BIOS, you need to enter it and write down each and every setting that is listed on the below template.  If you find it easier to do so, copy and paste the template into a Notebook or Word document and print it out, then go into your BIOS and fill in each line by hand, then log back into the forums, copy and paste the template again in the response box to this thread and fill it in using what you hand wrote down.  Please list all numeric values next to the word "Auto" that you see next to a setting in your BIOS...do not delete the word auto, or we will not know that it is an automatic setting and not one that you manually changed.  List all of your hardware to include the RAM brand and part number.  It is written on the stick of RAM, if you do not have the packaging.  Please list the recommended timings and voltage that is written on the stick of RAM.  To find your BIOS version, which we must know, when you first boot your PC, it will flash rather quickly toward the top portion of your screen.  It will say DZ15, DZ17, etc.  We cannot help you without all of the information that I have just requested.

Fort starters change this to 2T:  Command Per Clock: [*T] 1t
There are cases where 1T works, but it is more typical to have it at 2T.  It's worth a try anyway.  After you make the change in the BIOS, you will have to press F10 to save your changes.  thorne

ok srry i had listed that all earlyer in the post
