DDR3 almost pointless?

[Kewl Munky]

I'm currently reading on this tomshardware.com article on DDR2 vs DDR3. It seems that DDR2 800 and DDR2 1066 are better than DDR3 800 and DDR3 1066. They almost perfectly match in performance, except the DDR2 versions have 100Mhz more memory clock. If you think about that, and the fact that DDR3 is so exspensive, I think it's really pointless to get DDR3 right now unless you are getting DDR3 that's above 1066.

Yes.

Look at it this way, the same thing was said when it went from simms to SDRAM/ from SDRAM to DDR/ from DDR to DDR2 and now from DDR2 to DDR3. Usually when new ram first comes out its timming is alittle higher than the higher performance lower timming Ram before it

 

[Kewl Munky]

So they are correct when they say that at this current time DDR3 RAM is nearly pointless?

Maybe it will be worth it in a year?

 

[Cromewell]

Right now, there is no reason to get it other than to say you have DDR3. It could be a year or it could be less, it depends on if people are forced to get DDR3 with new chipsets when they come out.

DDR2 800 and DDR3 800 both have the same memory clock, what do you mean that DDR2 versions have 100Mhz more memory clock?

 

[Intel_man]

I've heard that DDR3's are suppose to run 1/3 faster than DDR2 rams.

Look on the charts and compare them. Second column for both of them. Also the DDR2 has faster cycle time.

 

[just a noob]

currently one of the 790i motherboards (don't know if it is all of them) actully cannot take ddr2 memory

 

[Kewl Munky]

I thought all DDR3 slots could use DDR2 since it's the same pins, like the PCI-E 2.0 and x16, though not both ways.

No, you can't interchange them. Look at the difference between the 2... the notch is in a different location on both of them, therefore, you can't use ddr2 in ddr3 boards or vice versa.

Nope, they run at different voltages and are designed differently. They moved the slot so people won't confuse the two and try to install DDR3 in a DDR2 slot and vice versa.

 

[Kewl Munky]

But how come some boards are claimed to support both? Or do they have like 2 slots for DDR2 and 2 for DDR3?

 

[johnb35]

They can support both but not at the same time. You have slots for ddr2 and different slots for ddr3.
