MB suports/DDR400 but will suport DDR500 too?

[dragosgorjan]

I want to change my 2x512DDR400 with 2x512DDR500 and to raise the FSB at 250 but i don't know if my MB can handle.
I have a good cooling overall system(this is not a problem)but i thinking about the FSB800 wich is maximum,and with 250 will be 1000 and another thing is that the MB suport DDR400 not DDR500.
I need an advice if is a safe change without damaging the MB or others problems
And the DDR2/533 are slower than DDR400?(the higher timings for DDR2 makes the diference, but when a higher frequency is reach there are faster?)

Asus P5GD1/P4 630

Correct me if I'm wrong, but your board only support DDR1, right? If so there is no 'official' support for DDR500 but you could buy it and see how high your FSB will go. I'm not an Intel expert but you may get it up to that. Any time you overclock you risk damage.

I now that official its not suporting DDR500 but there is any MB with DDR500 official suport?
The FSB could reach 250 without problems with proper MB/CPU/RAM cooling.

DDR500 isn't officialy ratified by JEDEC so nobody officially supports it. It's the same with DD2800, there are plenty of mobos and memory capable of it but it's not the official standard.

So in this case i have to buy 20 MB to see what MB support DDR500.
The question is: If my MB supports DDR500?
I think that theoreticaly yes because in BIOS FSB could reach 400,i can presume that the Asus engineers didn't put this number just for impression..I dont want fsb 400 but 250 i think is reasonable

Someone correct me if I'm wrong here.


When they say it supports DDR400 that means it's only running at a FSB of 200, so an FSB of 250 means your running DDR250. You can always try clocking it at 250 and see what happens, but you're risking damage to your system.

all you need to do to verify if your motherboard will run DDR 500 RAM is go into your bios and check the FSB and RAM clock settings. If there is a setting for FSB 250 and/or RAM 500MHz, then your board can run it. If not, then no. I don't think there is a board made these days that won't let you go at least that high if you want, so the answer is most likely yes.

Yes, your motherboard will run at DDR500 but it's not supported by the manufacturer, i.e. do so at your own risk!

All motherboards that support DDR400 also support DDR500. Memory has no speed of its own, the board sets it. So DDR500 will run at DDR400 on a board that supports DDR400.

The only way to make DDR500 run at full speed is to overclock. It will run in any DDR400 board, at DD400 speed.
