| 115917 | 2003-01-22 03:59:00 | I have been looking to purchase more RAM for my system. I need PC133 SDRAM, and would like to get at least 256 more (maybe even 512). I have seen advertised 256MB for $69, and 256MB Double Sided $89 What is the difference, and which is better? Thanks, Craig. |

| 115918 | 2003-01-22 04:03:00 | I would always just go down to the shop, to DTC Computers (always depending on whos cheapest from Price Spy) and get one of their 256 PC133 SD RAM for $48.95 +GST Check out http:www.pricespy.co.nz |

| 115919 | 2003-01-22 04:28:00 | Yeah, thats what I usually do - but I am after info here: What is the difference between double and single sided RAM, which do I need, and is there any performance difference? I would be happy to pay the higher price for the double sided RAM if it meant better performance.... Craig. |

| 115920 | 2003-01-22 04:28:00 | some pc's won't take large amounts of ram per bank(side). 256 single sided has all 256meg on one bank. however the motherboard may only be able to take 128 per bank so you have to get a 256 double sided which has 128 on each bank(side). | tweak'e (174) | ||
| 115921 | 2003-01-22 04:31:00 | It really depends how what your motherboard can take like tweak 'e said..... Check out the manual, or can you tell us the model... No it does not really mean better performace, some people (less of the market) just need it as a upgrade because their mobo can't take it. So like I said, find out from your manual or tell us what model it is... the motherboard |

| 115922 | 2003-01-22 04:38:00 | Ok, I am guessing I can take single sided 256, as I already have a stick of that in there. I can see now why having the two types is necessary and all. I know one thing - i wont be paying $20 more for it tho!! Cheers, Craig. |

| 115923 | 2003-01-22 08:39:00 | It gets worse... double sided and double banked aren't necessarily the same - you can have double sided (chips mounted on both sides of the stick), but not have double banked memory. The terms are used a bit loosely :| | wuppo (41) | ||
| 115924 | 2003-01-22 08:43:00 | mmm....ok. can you explain it a bit more please :) | tweak'e (174) | ||
| 115925 | 2003-01-22 09:00:00 | An example of 256MB memory: You can have a stick with 8 chips on one side, where the chips are internally 16Mb x 16 - this gives 2 logical banks. Alternatively, you can have a stick with 8 chips per side, with a chip internal configuration of 32Mb x 4 - this gives 1 logical bank. The type of chip is all important in the config of the module :| |
