#5 - Q/A: 6GB of DDR3 vs 8GB of DDR2

I was building a new computer and was wondering if 6 gbs of DDR3 memory was bettter then 8 gbs of DDR2 memory, im not really on a budget so cost isn't a factor for me.

hi im thinking about building a pc but i can only really afford ddr2 is it worth the money that it costs or not?

[Yoda8232]

@bammargeraskate96 DDR3 is cheaper than DDR2 because it's mass-produced now.

You missed the point about the CAS Latency. You can get DDR2 800 now that has a rated CAS Latency of 4, which will easily outperform DDR3 1066 with a CAS Latency of 8 or 9. Just because it's faster doesn't always mean it's better. You have to take into account the CAS Latency.

[Yoda8232]

Yes you are very true about the CAS Latency, the thing is when you buy DDR3

your not going to buy DDR3 1066 which is easily availible in DDR2 form. I'm talking

about DDR3 1600 or more is when the difference counts.

And with any RAM you can always lower the timings as much as you can but if you compare DDR3 2000 to DDR2

1066 is a major difference regardless of the latencies.

[SteelCity1981]

Well a lot of namebrand computers come with DDR3 1066 now, which is a total waste, other then maybe saving a little more power consumption you are acutally going backwards in performance over DDR2 1066 or even DDR2 800 with good latency timings.

Yeah I'm not talking about branded PC, talking about DIY. As this user was a DIY user.

ddr2 is acessed much faster because of the much tighter timeings

I thought I was watching that 70's show, thanks fezz... You know that queer kid on the show lol . Oh I hear foot steps you better get out of that basement

hei yoda... i was wonderin if a 128 bit or 64 bit interface cud run on a 32 bit processor.... i m actually plannin 2 upgr8.... pls reply soon......

[blowupuate13]

i use 16 gb of ddr3

@LFCforEver12341 It's def worth an upgrade of ram with either DDR3 or DDR2 1066 seeing how the DDR2 667 is bottlenecking your cpu. As for which to get it depends. If you are on a budget, then it would be cheaper just upgrading to DDR2 1066 rather then spending money on a new motherboard and ram.

[LFCforEver12341]

@SteelCity1981 hey, ive currenly got a ddr2 motherboard with a amd 550 x2 processor, and 667 mhz ram, is it worth upgrading to 1066 mhz ram or should i get a new motherboard with ddr3 to support 1600 mhz, im on a budget and want to know if its worth doing these things.

DDR3 has higher bandwidth and I am going to guess they want it on a X58 board (since they asked about 6GB which is most common on X58 boards) which means he is looking at 3 channels for the RAM instead of the 2 he would get on DDR2. DDR3 also produces less heat due to lower voltages. However, DDR2 has better latencies. Also, I have seen DDR2 RAM outperform DDR3 RAM....
