I have a AMD Phenom X4 9600 CPU. I purchased 8 gigs of DDR2 Ram for it. It will only recognize 7 Gigs. When I add 8 Gigs it will not boot.
I mostly use it for Auto Cad, and Photoshop, both are Memory HOGS.
Crucial Memory is: (2) 4GB kit (2GBx2), 240-pin DIMM, DDR2 PC2-6400 memory.
I'm running Win 7 Ultimate SP1 64-bit OS.
the ram can be found here: link
I haven't done anything to my Quad core. I took it out of the box and plugged it in. I want to know if I'm getting the most out of my computer. I'd like to get all 8 Gigs of memory out of it, and if there is anything I can do to boost performance for running these 2 programs I'd like to do this as well.
I have read in places that I might need to boost the memory Voltage in the bios as well as change the timing. But I'm new to playing with this stuff so I don't want to screw anything up.
Thanks for your time and help,
Jig

I think the mobo would auto-vault up to 1.8v.
Anyway, what motherboard do you own?

FWIW, your motherboard should support the amount of ram at the speed you gave, so worth looking at your voltages etc.

Is the manual going to tell me what my timing should be at? like I said before this is ALL VERY NEW to me.
I guess what I'm asking is if I change the Voltage does that mean the timing changes as well?
Is there anything else I can do to increase the performance for the 2 programs I'm using?

I don't even know what I'm looking for. I consider myself a a newbie but I do have some computer knowledge. I don't know where to find the BIOS let alone change it. and now I'm starting to wonder if this is over my head.
Is this an easy task?

bios with the motherboard manual will tell you that.
Where do I go to look at or open the BOIS?

I can see the installed Memory, But I am not able to go into it and make any changes.
I can see that it is a Phoenix _ AwardBIOS CMOS Setup Utility
Core Version: V6.0
BIOS Version 5.17
model number: m8400f
Product number KJ377AAR-AB

Is this what you are asking me to find? If so I don't see anywhere were it tells me to be able to change something locked in the BOIS.

HP's poor documentation and tech help has caused me to refrain from buying their products. Opening the bios on some machines is a little tricky as the key (Del,F2,F10,F12 or whatever) must be pressed at the exact right moment during the post boot procedure. Several key presses after the machine is turned on is sometimes necessary.

I just found this.

I can't go past step 3. Because my operating system is not listed.
