DDR3 Ram

[pliskin_wolf]

ok well here is a link that explain how DDR3 operates, and it says it doubles effectiveness. soo im not sure how it will compare, but im guessing that it will be like in higher ram 8g DDR2= 4G DDR3

this is an old page, but explains DDR3, and how it operates.

here is pretty much the only thing i could find on some quality ram testing, but they didnt use vista which kinda defeats the purpose of DDR3 interfacing, xp from what iv gathered does not support it correctly so this wont be 100% accurate, but will add light to the situation.

Source: DDR2 vs DDR3 tested head to head

[connnnn]

Personally I consider the inquirer more of a tabloid than a reliable source...

here's a good DDR3 round up from Anandtech

They both basically support the same idea though: DDR3 is coming along nicely, and certainly much faster than DDR2 did (the micron z9's are proving almost as impressive as their predecessors), but the price/performance ratio just isn't there yet for value let alone budget consumers. Give it another 6 months of fine tuning and you won't be buying DDR2 anymore.

yeah i read that one too, but i wanted some numbers to compare. im already not going to buy DDR2 when i get my new system im getting DDR3 no sense in buying something that is going to out date its self soon.

Well DDR2-800 and above will all be perfectly adequate for the next few years in my opinion. You might squeeze a few percentage points more from getting incrementally better RAM, but it all comes down to whether you get more additional performance spending that money on a better CPU/GPU instead. Right now DDR2-1066 has a pretty huge price premium as it is (equivalent models are sometimes more than double the price for pretty small performance gains; you could spend that extra $100 on a much better processor and see better improvements), and DDR3 is even higher, and both give decent but not mindblowing performance steps. So ultimately it just comes down to price at the time of upgrading. And I believe there's an assortment of mobos being made that support DDR2 and 3. So basically you really can't go wrong with spending whatever spare change you happen to have on RAM right now.

[pliskin_wolf]

the DDR2, and DDR3 mobos have some severe bio errors of course this is some really complex stuff going on to do that. Though like to future proof myself

[vircotto]

Future proofing very good

I find it odd how I have never heard of DDR3, and it's been out since early 2006?! O_o

Normally I would have heard about this or something.

I still fix peoples computers that have sdram or even fpm lordy my school have computers like that for basic training lol.

At the moment DDR2 is a lot faster than DDR3, if you look at the latency of DDR3 in comparison to DDR2 it is quite different on most sticks and as gamersit is pretty much all about the latency of your memory.

[FTB]

higher latency numbers do not equal slower ram. DDR3 1333 with a CAS latency of 8 is exactly the same speed as DDR2 667 with a CAS latency of 4. Latency is not the measure of time but rather how many cycles are completed. the DDR3 performs 8 clock cycles in 12ns where the DDR2 performs 4 clock cycles in 12ns. it actually takes the DDR3 1.5ns for one clock cycle compared to 3ns for the DDR2.

Oh nice, that is a very good article and thanks for correcting e, I really did not kow that.

I only just recently upgraded my PC and went for DDR2 simply because the DDR3 latency was so high but now I have read that maybe I should have gone with the DDR3 Doh!

Nice read anyway, thanks!

You could buy a complete gaming system, Screen and all for the price there asking for two gigs of ddr3.

Get the Gigabyte P35c board, has ddr2 and ddr3 slots!

just grab up some ddr2 9200 or 9600, crank up your cpu clock, and wait for ddr3 prices to fall!

[That Other Guy]

Sounds like a plan ;3

Personally, I think 9200 / 9600 prices are too high...

I got myself 2GB of PC2-8500 and overclocked it to 9600... Runs like a charm and haven't gotten any problems since then (3-4 months, ran several times memtest without errors).
