Memory problems not running at full speed

I have a Epox 8kda3+. motherboard i just bought "Corsair Value Select - Minne - 2 GB ( 2 x 1 GB ) - DIMM 184-pin - DDR - 400 MHz / PC3200 - ej buffrad - icke ECC" memorys i had 2x 512 since before...

Now here is my problem when i have 1 memory in slot it runs in 400 MHz as intended. But when i put in 2 memorys on the motherboard is just wanna run 366 Mhz..

And now when i got 2x 1GB memorys and 1x 512MB memory total of 2512 GB memory it just wanna run in 200MHz "CpuZ says 100mhz frequency core"??

Please help me with this problem as i dont want the memorys to run slower just bc i have 3 of them??

How do i get it back up to 400Mhz "200mhz core" speed with all 3 memory slots taken.. If i change in bios to maxx alowed 200mhz then it wont get past showing memory and stop there...

All the Memorys are DDR PC 3200 running at 400MHz..

If i take them out and put em in and start up one by one.. it runs each in 400MHz. But when i try more then one it clocks down itself and with 3 in they only run at half speed.. Need help badly as i have no idea what 2 do.

This is a limitation of the chipset and memory controller. You may be able to enter the as advised and set the timings manually. However, you are most likely going to need to remove the 2 x 512mb to run DDR400 or faster.

as stated previously..

many socket 754 mobo's/cpu's have issues running 3 ram sticks at full speed.. This is more of an issue with the CPU than the chipset, since the memory controller is integrated in the cpu.

Not much you can do about it, except yell at the maker of the chip.

This is an url to the CpuZ speccs of my computer with the motherboard im running at the moment..

Yes but how should i set the timings what are they suppose 2 be at?
I mean i dont wanna fry the memorys for having to switched them up to high...

http://www.teamgroup.com.tw/teamgr [...] &pl2_id=11 is the 512MB memory im using atm.

and

http://www.corsair.com/products/value_select.aspx is the 2x1GB memorys im using.. brand new. VS2GBKIT400C3 is the part number.

So with those 2 what voltage should i run and what timings?
Im a complete newb to the whole memory settings so if i can get the names on the stuff im suppose to change and 2 what.. would be super thnx..

on almost all DDR boards the case was simply a matter of how many sticks you had installed. 2 sticks could run at 400 if the sticks were in fact DDR400 or PC3200. 3 sticks no matter what have a max of 333 or PC2700, and 4 sticks (even at ddr400) would run at 266 PC2100)

Yeah 200mhz true clock speed, 400mhz effective speed as it is double data rate (D D R) - 200mhz x 2 (double) = 400mhz effective

ditch the 512 its worthless and unmatched, you wont miss it trust me, the more sticks you have the more issues you will have.
