Gigabyte 8KNXP and RAM problem

Ok so I finally upgrade to get new ram and it don't want to work properly.

I originally had Kingston ValueRAM KVR 400X64C3AK2/512, I then bought another kit of Kingston ValueRAM with the same specs so to get a total of 1 GB running at Dual channel DDR 400. My old kit was installed on Channel A : DIMM 1 & Channel B : DIMM 4 and i installed the new kit on Channel A : DIMM 2 & Channel B : DIMM 5. And every time i try to start the computer i either get a blank screen or a blank screen with an alarm coming from the speaker. I took out the new kit of Kingston and the computer worked properly. I have tried them in every configuration and still the same problem. I can't get the new kit to work in hand with old kit, even more i can't get the new kit to work separately whether in single channel mode or dual channel mode. The only time i got it to work is when i used the old kit with one module of the new kit and thus running in a Single channel mode with a total of 768 MB, but even with this configuration i experienced serious system crashes.

So i took the new kit out and tried it at one of my friends who has a different gigabyte mobo which uses the same kind of memory. He has 4 x 256 MB Kingston ValueRAM running in a dual channel mode and surprisingly my new kit worked out fine.

My mobo is Gigabyte GA-8KNXP Revision 1.0

Any ideas on what I should do to get this ram working, or am I stuck with only 512 MB of ram for this board?

Help I'm stuck with 512.
 
You know, thats a tough one. If the New kit by itself does not work in your machine. (In DIMM 1 and 4), then it would seem to be bad RAM since your old kit works in those slots. But then again they worked in another machine just fine.

The manual says that is support DDR400 and up to a 1GB Chip per slot.

In the memory section it also says that 4 DIMMS can be singel or double sided (If you go to 6 DIMMS, 4 of them must be single sided)

Would it be possible to borrow the RAM out of your friend's machine and test those sticks in slots 2 and 5?

Does his machine actually clock the ram at 400? If he has a slower memory clock it could be that the chips are bad but not running fast enough to exploit the flaw (Off the wall thought).
 
I will try to borrow the RAM from my friend and test them as you mentioned.

I am not really an enthusiast so can you tell me how to know if my computer actually clock the ram at 400?

Thanks for the help.
 
I used CPU-Z on my computer and my friend's computer ..... We both are running on Dual DDR 400.
 
Oh well, here is what i did ....

1- I have posted my problem in 5 different computer forums as HardOCP, Tom's Hardware Guide, AnandTech, ABXzone and CNET.
2- I have searched and read many reviews throughout a Google search.
3- I have read the mobo's manual and tried to troubleshoot the problem.
4- I have e-mailed both Gigabyte and Kingston 3 days ago and i haven't yet receiced any response ... What kind of support is that? ... Is this normal?

None of the very few replies really helped to solve the problem, neither reading other posts and many reviews and nor the troubleshooting.

So i went back to my basic concept in life ... Trial and Error ... which is the only way you could really learn.

Most of the posts and reviews i read, were pointing to flashing or updating the bios or resetting the CMOS and then loading the fail safe defaults from the bios. I have never done any of these before and i have read about nightmares from flashing the bios. So i decided to focus on the CMOS section, but then again i really don't know the consequences of resetting it. I found myself stuck with loading the fail safe defaults. I did load the fail safe defaults, then i installed the new Kingston kit. I started the computer and it worked very smooth. I then used memtest86 and i got no errors.

Now i have 1 Gig of RAM running on Dual DDR 400.

Anyway thanks for the help, i really appreciate it.
