I am due a system upgrade soon, and am debating what type of RAM to go for. I was going to get DDR RAM, but I am wondering if the speed benefits it has over PC133 are really worth the extra price?

Extra price?
Its about the same price isnt it?
eg=
256Mb DDR (2100) PC266
Online Price £27.67 £32.51 Including VAT at 17.5%
256Mb Dane-Elec CUBE SDRAM PC133
Online Price £25.80 £30.32 Including VAT at 17.5%

If I was building a new system I'd deffo go for it....

if its an amd system then get ddr ram. if its a p3 get sdram. if its a p4 get rdram. pretty simple. ram is cheap so buy a lot.

i have a gig of sdram running cas 2-2-2 on my system. its pretty sweet.

for ddr and sdram check out

I have 512MB PC2100 DDR with an Athlon 1.4Ghz, and the rig runs sweeet! although realistically speaking, the differences between using DDR and SDR isnt THAT perceptible..

DDR all the way. I have about the same set-up as Xeven's and it's all good.

The FSB speed makes more of a difference than DDr ram from Sdr ram... But for top performance, DDR ram is better than sdr even if only slightly..

 

[Zephon]

Get DDR. The price difference is very small and you can get some speed improvements with DDR, mainly with programs that depend on high transfer rates(DDR 2,1GB/s against SDR 1GB/s, although you will never experince a double speed improvement).

are motherboardsthat support ddr ram, backwards compatible with old PC100 and PC133 ram?

DDR ram sticks have a more connections so no it isnt..

 

[fivefeet8]

It depends on the motherboard.. A few DDr ram mobos also have sdr ram slots for pc100 and pc133..

DDR is cheap and d best also for pentium 3 but u wll be limited to via chipsets only

Actually there is no advantage of using DDR with the P3..

If there was a DDR memory solution for the P3 it won't be synchronous to the FSB speed. Therefore, I think it would have just as much of an advantage as the Athlon.

I think i will be combining it with an Athlon (1.4 ghz + maybe), or a 1 GHZ duron, depending on how tight cash is @ the time Is there any imprvements with DDR ram and athlon (xps)?

 

[fivefeet8]

NO.. The same type of DDr Ram is used in Athlon xp platforms.. I would like to get a hold of DDR 333 mhz ram though and combine it with an athlon xp and a mobo with support for 333 mhz ram.. There are a few mobos coming out with 333mhz DDR ram support and ATA 133..

 

[dn]

what is the price difference in normal PC1200 and this "333Mhz" DDR RAM?

Check there.. and goto www.pricewatch.com for other prices of ram..

The price difference is nominal.. Or not that much more..

actually there were DDR solutions for the p3 using the via apollo pro 266. And benchmarks showed that there is 0% or at most less that 1% increase in performance, illustrating that the p3 cannot take advantage of the higher memory bandwidth offered by DDR. or maybe via's chipset is crap.. in any case.. there is no advantage of using the DDR .
