Hi all:)

I currently have 256MB of 533 MHz Apacer DDR2 ram in my machine. I looking to purchase a further 1GB of ram of the same brand and speed. I was just checking prices here and I would like to know what the difference between the different 533Mhz Apacer rams are to cause such big differences in the prices of the 1gb sticks?:confused:

Thanks:)
 
The megabytes are different. The Mhz shouldn't have an effect the price.

You have 256mb and now you want 1024mb, that's 1024 more megabytes, it isn't that expensive when looking at it ;)

maybe he means the dif in price where ECC reg modules are alot more expensive than non-ecc reg modules :confused:
 
I've never had a problem with RAM, even the cheapest brands on the market.

Running 2 No-name brand 1GB 667MHz chips in Dual-DDR mode and I haven't had a single problem. And the speed is amazing!
 
ECC Short for Error-Correcting Code memory, a type of memory that includes special circuitry for testing the accuracy of data as it passes in and out of memory. Usually used in servers.

So am i correct in assuming ECC modules are more stable and reliable?

My board can only take 400MHz or 533Mhz DDR2 :(

So the cheaper R372.60 above shouldn't be a problem then?:D

Have you actually tested RAM faster than PC4200 (aka 533mhz), the DDR2 specs require RAM modules to support lower operation speeds and unless your motherboard is out of spec/cannot correctly read the module SPD it *should* work with even the fastest DDR2 modules.

Anyway that aside, no offense but the RAM you have isn't worth spit (not because of the brand but because it's 256mb). You'd be better suited taking it out and just putting in 1gig module on it's own. The extra 256mb is only going to make your system less stable in a worst case scenario or slower in a best case scenario.

Also why don't you buy another brand like Kingston for example, their chips are quite cheap and great quality...

Although I have to admit I haven't tried your brand and it could be great (recently tried Super Talent myself, only to discover it's excellent memory, it's cheap and lifetime warrenty! ;) )

Oh yeah and on the topic of ECC modules, they have no purpose in the desktop environment, they have higher latencies than standard modules and offer no benefit other than if one module fails, the system can continue to run on remaining working modules, the modules don't regularly correct errors that is an incorrect assumption, that would mean the module is damaged, and mathematically it's very inefficient.

Perhaps you have a link to an online store so I can check it out before I make a final decision?:)

I used to use Kingston which is a recognized high quality, but recently started ONLY buying Super Talent for 3 reasons:

+ They are cheap
+ Lifetime Warrenty
+ The company has been in the business for a very long time but they weren't very impressive, but they've changed their strategy to compete with the top end modules and so far reviews are very positive (Kinda like the turn around ASRock motherboards made).

Honestly if you aren't going to overclock I would say give Super Talent a try consider you get a Lifetime warranty, can't really beat that at the prices they're selling. Although it's worth mention that my Super Talent modules (667mhz 1gig modules x2) overclock very comfortable to 800mhz(4-4-4-13-2T), so in that arena I don't think their too bad either.

Perhaps you could also give Cyberdyne Systems a try ( www.cyberdyne.co.za ), although they are located in Johannesburg so you might need to organize a courier to collect from them (they're shipping is ridiculously expensive in my opinion, for example from Joh->Pta is R175!), but they are definitely the cheapest for both Kingston and Super Talent.
