I did try out the looser timings at 2T. I think that I read somewhere that DDR400 Dual Channel will only run at 2T with Athlon X2 CPUs. I also tried 1T just in case, and no help. One thing I noticed was that the system did not like to boot / reboot on the first try with manual memory settings. Once I put them back to Auto, the system was rebooting on the first try. Do you want me to post some other settings?Originally posted by: designit
try all rams to the looser settings (the one you said shows looser), and 2T command rate.
4gig will require 2T . the command rate is the one called "MA" timing, right below TRP(memory clock setting to manual).
post your settings and we will see what need to be adjusted.
I also learned that 3 sticks of RAM will report in Windows as 2.50 GB, but 4 sticks still report as 2.00 GB! See the other thread that I mentioned - at least one other person had the same results using an X2 4400+ on an ASRock motherboard with a 256MB GeForce video card.
EDIT: The OP in the other thread also had an X2 and and ASRock motherboard, but with a low-end ATI video card. The common link looks like X2 and ASRock.
If you set your memory timing on auto, the bios will reduce them to 333mhz and will use the lossest timing possible to make the board post.
This is why you should set memory timing manualy. But have to find out what they spec to.
google the memory serial #, and you will most probably find a pdf file for them or some forum or review site on them.
I posted a link to some bios settings that will get you going untill you resolve the issues you'r having.
It does not matter if you use X2, opteron, of FX55, or any athlon cpu, 4 dimms occupied will force 2T. That is unfortunate, but 2T is not as bad as you might believe. It is only about 2-4% performance reduction. but more memory in 2T, is better than less memory in 1T.
Sorry - I gues everything isn't on Auto - I did manually set the memory clock to DDR400. The memory timings (2-3-2-5 btw) were on the OCZ packaging, but since other things like voltage settings were not, I phoned OCZ, and had a tech walk me through all of the BIOS settings to match my RAM.
With the apps I'm running right now, x64 is not an option. When I did my original research, I had the impression that 32-bit could handle up to 4GB.
