Memory Question

Rob,

Thank you for using the Dell Community Forum.
With a 533Mhz FSB the memory is reduced to 333Mhz instead of running at the normal 400Mhz.
The 6.4GB transfer rate posted on the site is the maximum transfer rate you
would get with a 800Mhz FSB and if you were using Dual Channel DDR memory.
In Single Channel with a 400Mhz memory speed you would only get 3.2GB transfer rate.
With a 533Mhz FSB and memory speed reduced to 333Mhz, you would get 2.7GB single channel, and 5.4GB dual channel transfer rates.

Thank-you, Karell,

                 That is what I thought, but that is NOT what Dell is advertising. It is "false" advertising, is it not, the transfer rate of 6.4 per second, it is a big difference from the bus speeds, so why doe's Dell list it as 6.4Gb ps transfer? (It is in the configuration pages where consumers peruse the info to make decisions to purchase, I might not be happy with the 8300 as is, beings now, it is not as advertised) Thank-you for your time and input, it is much appreciated, Sincerely, Rob :)

Hello Karell :)

              Thank-you for responding, if you can, would you be able to give the specs or at least some details on the chipset, please? Much appreciated, take care, have a great weekend, Sincerely, Rob :)

Karell,

I ordered an 8300 (Its on its way ).  I ordered it with the 3.06G cpu and 512MB DDR SDRAM.  Here are my questions:

Is the DDR SDRAM called "Dual Channel" OR is the Dual Channel referring to the mobo?  So is it ordinary DDR SDRAM? 

Could you please give the specs. of the RAM in case I want to buy some more?  For Example:  Is it PC2700? Non-Parity? Unbuffered? Non-ECC? Is it a certain speed?

It seems nearly impossible to collect this information on this confusing configuration.  Any assistance you can provide would be greatly appreciated.

Thanks,

_Murf_

 Good Questions, Murf,

                 It better be PC 3200 Memory, DDR Dual Channel, otherwise, they will be in deep with they way they promoted this system. It is still listed as PC 3200 Dual Channel, at 6.4 GB per second transfer, but, as Karell already pointed out, the 533 bus make's the speed only 5.4 GB transfer speed, which the PC 3200 memory would be able to "step-down" to, it will still be a kick asz system, but, Please, Karell, we want the specs and more! Is it the 875P chipset, ready for Serial ATA? Raid? Thanks, Sincerely, Rob

To configure memory for your computer, click here for Crucial's memory configurator. Crucial is a division of Micron, one of the largest manufacturers of memory and a supplier of Dell's. Memory selected via their configurator is guaranteed to fit, and all memory has a lifetime warranty - plus they provide priority shipping at no additional cost for most orders. There is NO impact to your Dell warranty by adding Crucial memory (or other hardware or software for that matter).

$93.99 for a 512mb stick.

 Hey Murf,

               Here are the specs for the memory shipping in my system, can you make out the "cryptic" serial code they use? It doe's state "Dual In-Line", they better have it as Dual channel, that is all I am saying for now, and it better be PC3200, I really am gonna miss the basterd child of the memory family, long live Rambus!!!!....Rob

The spec's indicates two 512Mb 333MHz DDR DIMM's (dual in-line memory module).

So you have 1Gb memory with a max speed of 5.4Gb/sec in your 8300 system.

To use the max memory-speed in a 8300 you need the more expensive DDR 400MHz memory (than you get the full 6.4Gb/sec memory access).

Note: Only the 3.00GHz 800MHz FSB processor (or better) would use the full 6.4Gb/sec...

 

Rob,

Don't mean to cut anyone off, just want to keep my answers in order.
You can find the system specs here.
The specs for the chipset are better viewed on the Intel web page here.

The 8300 with the 533fsb is just as fast as the XPS on many marks (XPS my Man, XPS) and faster on quite a few of the benchmrks.. They just had a lapse or a brain tart.......

Murf,

Dual Channel is part of the motherboard chipset technology.
The memory is still standard DDR memory.
You can find the system specs here.
The specs for the chipset are better viewed on the Intel web page here.

Here is more info on the memory support:
Name------Clock Speed-------Single Channel---------Dual Channel
PC1600----200MHz------------Not supported----------Not supported
PC2100----266MHz------------2.1GBps----------------4.2GBps
PC2700----333MHz------------2.7GBps----------------5.4GBps
PC3200----400MHz------------3.2GBps----------------6.4GBps

Dell uses NON-ECC memory in default configurations.

Maybe Dell needs the fast memory and processors for the new XPC...

That's quite all right, Karell, but that still doe's not explain why Dell listed PC3200 DDR as the memory that was being sold with the 8300 systems all last week, it was either false advertising, deceptive advertising, or just plain good 'ol fashion careless and not giving a shoot about the consumer who made their decisions based on what the configurator "promised" would be a "Custom Built for You" Dell computer.. A small Mom and Pop business wouldn't make such a screw up... Rob

Rick,

Thanks for taking the time to write such a detailed explanation!  It is good info.  I'll look into it.  I appreciate it.

Murf

  Karell,

Thanks for the info.  I appreciate it!
