ddr3 for the intel x48bt2


rakotovao

Recommended Posts

I have bought an intel x48BT2 motherboard. I would like to know which ddr3 1600 memory corsair can I use with it? I do not want to overclock. I have heard that with this motherboard it needs always some tweaking to reach the 1600 frequency. I have seen in this forum that sometimes there are some problems with this x48bt2 concerning memory. is there anyone who can help me? thanks.

With that board I would advise you to run at the speed of the FSB. You have a 333 X 4 = 1333FSB processor. So, I advise you to buy 2 X 2048 or 2 X 1024 of 1333Mhz DRAM. I do not advise you to populate all four DRAM slots as you will then have to drop your bandwidth. So, if you want 4GB, buy 2 X 2048 and if you want 2GB buy 2 X 1024.

You would need to overclock the processor to 400Mhz FSB (400 X 4 = 1600Mhz) to interface with DDR31600Mhz.

 

To leave the CPU at the Intel Spec necessitates DDR31333Mhz DRAM. Sometimes there are issues trying to get Intel boards to interface correctly which is why I advised DDR3 1333Mhz DRAM.

so, if I understand, I can not get profit with this 1600 without overclocking ( by using the intel quad 9650).

I especially buy this motherboard due to its 1600 frequency. If I use a 1600 memory, what is the process to reach the 1600? thank you.

It has already been stated, and you have confirmed that you understand it.

 

If you want to get 1600 Mhz memory and run it at full spec, and you do NOT want to overclock, then you need a CPU that has a 1600 Mhz FSB.

 

The only one currently out that would fit your board is the Intel Core 2 Extreme QX9770 - 1600 Mhz FSB, Socket 775.

 

So, you have to ask yourself, is the performance difference between the Q9650 and the QX9770 worth the high cost increase? Right now, the QX9770 is TRIPLE the cost of the Q9650. What are you going to use the system for?

thank you.

I want just to get profit of the 1600 with this x48bt2. I know that the price of the extreme is triple this is why I have bought the quad 9650. I do not know much about overclocking . what I do not understand is the difference between x48bt2 and the motherboard x38 if we can not get profit on it.

Download Memtest86+ V2.01 from--->

and extract the ISO image. Burn the ISO image to an CD-ROM disk.

Download CPU-z from
.
Performance

Host Clock Frequency Override = Manual
x Host Clock Frequency (Mhz) = 400

Memory Configuration

Reference Frequency = 400
Memory Frequency = 1600

tCL 9
tRCD 9
tRP 9

Boot to the Memtest CD and allow for two full passes. Then, if stable, enter Windows and run CPU-z. Post screenshots of CPU-z's CPU, Memory and SPD tabs.
