DDR or DDR2

post #1 of 12
Thread Starter 
Do you think DDR2 on 800 FSB CPU would performe or with DDR the same?
[Coz cpu bus speed is 200MHz(800/4) so cpu & mem bus 1:1 Ratio]

As i heard DDR2(533FSB) fits CPU with 1066FSB.
[Coz cpu bus speed is 266MHz(1066/4) so cpu & mem bus 1:1 Ratio]

Can anyone correct me if i'm wrong...Thanks.

DDR2 and DDR have different pin configurations, if im correct which would mean you cant use them on the same board so cant really compare performance.

I think it can be compared in Intel 915G chipset boards. For DDR2 INTEL D915GEV board & for INTEL DDR 915GAV. There aren't any defference between these two boards exept for the ddr & ddr2 slots.

(there maybe more boards with same chipsets but differ on ram slots.)

There are some motherboards that have both DDR and DDR2 slots, so that would be the best for a comparison.

So do anyone think ddr2 has more speed on fsb 800 boards?

no probably not, i would go with the DDR1 dimms, there cheaper and there more is more of a slection.

It depends if your board can support different FSB: DRAM ratios. If it can only use the stock 1:1 ratio then I would have to recommend using DDR1 memory as it works beter at the slower speeds due to its more efficient timings, even though they do not have a great effect on Intel systems.

If you can get a better FSB: DRAM ratio like 533MHz RAM with 800MHz FSB then I would go with DDR2 as it can really boost your bandwith at the higher speeds, more than DDR1.
However as its an Intel board I would think that only the standard 1:1 option is avaliable so DDR is most likely your best bet as you can get very good 400MHz DDR1 memory

Id go with DDR1 since DDR2 has horrible timings (like 6-6-6-15) if youre gonna be gaming on it.
Very nice!

my ddr2 ram runs at 540mhz and timmings of 3-2-2-4 i can take it up to
1000mhz with timmings of 4-5-5-10

i would hardly call that slow

I must have been looking at a crappy brand then.
