mercury_in_flames Posted November 28, 2005 Report Share Posted November 28, 2005 (edited) Well I want to put a 1 gig ram into my lap top. I would rather go for Kingston instead of other brands, but need some advice. Whats the difference between buffered and unbuffered ram? Ive got the link which says which RAM will go for my laptop but there are 2 256 mb cards and 2 1 gig cards.http://www.ec.kingston.com/ecom/configurat...&submit1=SearchWhats the difference between the 333mhz and 256mhz ram? They are both the same price. I've checked inside my laptop and it has two 256mb, 333 mhz cards.

Guest Stuge Posted November 28, 2005 Report Share Posted November 28, 2005 Buffered ram has a more complex IC. It has additional banks on-chip that hold data for 1 cycle before returning it to the CPU. This adds a bit of overhead (read: latency), but greatly improves the reliability of the RAM. Coupled with ECC, it ensures that the chances of an uncorrectable error occuring are hundreds of thousands of times less likely than with standard RAM.Under buffer DOESN`T HAVE THIS FEATUREWhat's the difference between buffered and unbuffered DIMMs?High density DIMMs have lots of chips on them and therefore possess a higher capacitive load on the address and control signals in comparison to lower density DIMMs. Some designers use redrive buffers on the DIMM to boost the signals to reduce system loading when compared to the same high density module without buffers. But the buffers introduce a small delay into the electrical signal, so adding buffers to a standard density module would have the effect of slowing down the signal, compared to the same low density module without buffers. Memory Upgrade help siteWhats the difference between the 333mhz and 256mhz ram?It is basically the speed at which the ram works....It is better to use two rams of 512mb of 333mhz rather then one ram of 1gb.But both rams should have same speed otherwise ur computer will not start b`coz it cannot Quote Link to comment Share on other sites More sharing options...
mercury_in_flames Posted November 28, 2005 Author Report Share Posted November 28, 2005 thing is I might want to add another 1 gig ram later on Quote Link to comment Share on other sites More sharing options...
Guest Stuge Posted December 3, 2005 Report Share Posted December 3, 2005 thing is I might want to add another 1 gig ram later on ←Then no problem go for 1gb ram instead for each slot. Quote Link to comment Share on other sites More sharing options...
ajitp Posted December 3, 2005 Report Share Posted December 3, 2005 hey greg, the key for upgrading ram is to make sure that the speeds are compatible with your motherboard. the different sticks of ram don't necessarily need to be of the same speed, but it's usually recommended to have two sticks of the same speed. Since you want to be able to upgrade later on, and add another stick, i'd get 1stick of 1GB running at 333mHz if that's the fastest speed your laptop will take.

Razorback Posted December 5, 2005 Report Share Posted December 5, 2005 buy a pair of 1 gig ram at 333mhz... but for using these two rams with the dual band, your motherboard should support dual band feature.. check your motherboards features for dualband...dual band give you the feature of doubling your rams bandwith.. if it is 2.7gig bandwith, then it goes to 5.4 gig...You can select kingston, it is nearly best i think... but be confident with your rams that they are kingston.. for this, look for kingston writing on the chips..

mercury_in_flames Posted December 5, 2005 Author Report Share Posted December 5, 2005 (edited) no the ones ive got right now arent kingston, but i wanted to go for them from what ive heard about them. I cant really be sure, I have the manual for the lap top, but am not sure. I am just being lazy here i admit it, but if anyone feels they have the time or expertise I'd appreciate your help. From looking at the kingston web site it says it supports 333mhz.I dont really understand the bandwith thing, I thought 1 gig ram = 1 gig bandwith>? Can you elaborate in lamen terms please?If u check out the link i put at the top, it says that the 333mhz are supported but will run at the slower speed, is that for real? So theres no point going for the faster one? Edited December 5, 2005 by mercury_in_flames Quote Link to comment Share on other sites More sharing options...
Razorback Posted December 5, 2005 Report Share Posted December 5, 2005 1gig (gigabyte) ram is not a bandwith value.. there must be written pc2700 or pc3200 etc.. this is the bandwith.. pc 2700 means 2700 mhz bandwith, i mean 2.7 gigaherz (ghz)You must first, find the model and the manufacturer of your motherboards.. then you can learn the features just copy pasting it to the GOOGLE...

mercury_in_flames Posted December 5, 2005 Author Report Share Posted December 5, 2005 are laptop models not given standard motherboards? Quote Link to comment Share on other sites More sharing options...

Guest Stuge Posted December 6, 2005 Report Share Posted December 6, 2005 are laptop models not given standard motherboards?←Hey Buddy,You will need to check which motherboard you are using right ?There are lots of motherboard manufacturers in the market like INTEL,Hp makes Hp motherboard etc...Can you tell me from which company you have brought your laptop like Hp,etc?

mercury_in_flames Posted December 6, 2005 Author Report Share Posted December 6, 2005 well u cant blame me for thinking there was a standard one for each model of lap top. I'll probably just take it to some crappy place like pc world and see what they say. Quote Link to comment Share on other sites More sharing options...
ajitp Posted December 6, 2005 Report Share Posted December 6, 2005 there's basically as many laptop motherboards as there are desktop motherboards. Quote Link to comment Share on other sites More sharing options...
