The 4 dimms are all labeled Kingston. But if you look at just the transfer per second rate you obviously have two different pairs not the identical across.

The timings are identical which is good. But the two pairs were made for Kingston by two separate companies. Kingmax Nanya as Maxman was pointing out there. I suspect if you installed the 4th dimm in the first slot with the other 3 and ran memtest on it for several hours you might find a few errors.

The SIW tool mentioned before would list all 4 dimms on one main screen showing far more detail about each one by itself.

As for mem test, last version 3.5 (or 2.5..nevermind ) just crush pc (restart) when i run it with all 4 dimms.

I discover new fact about my problem. PC wont start after "long" time being turned off, if you turn off/on lets say every 5 min it will always start. Which leads me to believe that it has something to do with power (and 4dimms and diff.memory type :) )

Now i left 3 dimms (2 old in dual ch. and 1 new) and turn off in bios "power on on 2 clicks" so it dont spend power (wireless mouse and keyboard receiver) on anything when its in turn off state.

If problem still be there i will go for 2 100% identical dimms with 2GB each.

Thanks everyone for help.

I have four dimm slots here for upto 8gb and simply went for 2gb dimms in order to replace the original pair of 1gb at the time when the prices finally were coming down. You should be able to pick up at this for a real bargain! Hope that works out for you.

I had a similar case. My new WinUltimate was working successfully but later updating new Windows Update package, in the morning I could not open even the bios
I had to change the board on the service.

Yes if you live in USA :P

2x 2GB DDR2 800 in my country is 100$+ and monthly paycheck is 500-800$

OUCH!

The pair of 2gb dimms in now were first seen priced about $300US when the 2gb size dimms were first coming available I waited until the price fell down enough right before the 7 betas were released to give the system a boost in preparation for the 64bit 7 as well as the extra ram needed when working with video.

Eventually the prices will come down where you are once you start seeing the prices on DDR3 memory dropping there. Since memory prices typically remain higher then other hardwares which tend to see prices fall faster the slow economy is one likely reason prices fell here a bit faster.

OK, just a small update on this problem.

PC is working perfectly with all 4 dimms inserted, it looks like memory isn't problem at all, it has something to do with power supply or motherboard and bios.

I changed 2 settings (bios):
1. Turned off - Power on by mouse
2. HPET mode changed from 32-bit to 64-bit.

First one must be the guilty one. Why? I don't know. In manual says that my power supply must have "at least 1A on the +5VSB" (and i don't have a clue did my power supply can do that), anyway, because of that 1A when i have 4 dimms installed, my PC -sometimes- show just blank screen.

If anyone knows where to see info about that 1A on my power supply it would be great. Here is link to my mini tower case with pre-installed power supply.

As for HEPT mode..according to manual its some irrelevant function so i think its not it.
My English is bad. Sorry.

Your case came with the supply?!

I can tell you from experience never buy a case with a supply included! The companies use the lowest end models they can find to dump in as a combo deal when those are often bottom shelf!

If your changes in the bios allowed all 4 dimms to be set at the same voltage and timings that would be part of the correction and better results you are seeing now however. Glad to see you made some real progress with that!
