ram question

Post by PToN »

sup i have 256 mb of ram ( PC133 sdram)

i dont know to much about ram

1.- is there any difference between PCI133 and PC133 ?.

NO RIGHT or yes ??

2.- i have 256 PC133 and i am going to buy some more the question is if i buy to sticks of 256 ( 2x256=512) would it work or it must be two stick of 128 each ??????

3.- do i have just to put them in the slots right nothing else or i have to gonfigure something

I've never heard of PCI 133.

Check the Mobo manual. If you're already running 1 256 stick another would most likely work too. If you have a low end motherboard it may have a limit as to what the chipset can handle.

The Motherboard book should show you how and where to install the memory. Memory slots are usually numbered 1,2,3. Load the mem in that order.

What motherboard are u using?? and what brand of memory?

Oh yeah, you just plug it in. You may need to change a few bios settings to optimize your memory.

i have a dual processor dual PIII able to handle 2Gb of ram

ok i have 2 sticks of 128 thats equal to 256

what i want to know if that i can buy 2 sticks of 256 each one so thats equal to 512 new ram

ok i have 256 + 512 NEW RAM WILL THAT WORK ????

I've never heard of PCI133 RAM....but the main difference, between RAM, is the PC150, PC133, PC100, etc, etc, the Number, refers to how high you can clock the memory too. 100 mhz, 133mhz, and so on, the higher is better

2.- i have 256 PC133 and i am going to buy some more the question is if i buy to sticks of 256 ( 2x256=512) would it work or it must be two stick of 128 each ??????

No, you can buy any size memory stick you want....make sure you motherboard can support it though....some older motherboards cant support the high density modules.

3.- do i have just to put them in the slots right nothing else or i have to gonfigure something

No, just put them in, they will work. Make sure they are in all the way, most newer motherboards, they will have retaining clips, make sure they are in the full upright position

no, faster RAM is backward compatable with slower-rated frequency buses.

in other words, if you have a system that is currently running at 133MHz (memory bus speed), and you put a stick of PC150 in, the PC150 will run just fine at 133MHz (PC133), or 100MHz (PC100). no need to change out the mainboard.

and as far as what you should buy, i would suggest going with good quality PC133. PC150 wont show much of an improvement since it will only be runiing at 133MHz. if you plan to overclock your system in the future, then i would get the PC150.

oh, one more thing.... you are running a dual-CPU mainboard, right? this dramatically increases the chances of there being either parity or ECC RAM already installed. i would try to find that out before making a purchase. installing ECC or parity RAM on a system with it enabled will not have desirable results.

if you dont know how to find out, you can download SiSoft Sandra 2001 from http://download.cnet.com/downloads/1,10 ... =&ca=10001 and install it. run the "mainboard information" module, and look around. it should tell you if its ECC or parity memory.

okay, here's a couple pics so you know what to look for. the top is my main system (non-ECC RAM), and the bottom is my fileserver (with ECC RAM, running in ECC mode). htis information is in the "mainboard information" module. scroll down and you should see the information (i outlined where you will see the kind of memory you have).

sup again

look i looked and i couldnt find that part maybe because its the freee version but i saw the difference between the 2 pics you posted and i saw that my memory has " 128MB SDRAM 6-1-1-1R 4-1-1-1W 3-3-3CL " so it must be ECC and not the " 128MB SDRAM 6-1-1-1R 4-1-1-1W 2-2-2CL " wich is shown on the on the first pic


so again wich one should i buy ECC right and another thing my bus speed for the memory appears at 147Mhz so should i buy the PC150 or the PC133

well, the RAM timing values (6-1-1-1R 4-1-1-1W 3-3-3CL) are independant of the parity or ECC function, so its still kinda up in the air (whether its ECC, parity or non-parity).

i am not sure as to why the information showed in my screen(s) is not showing in yours. maybe because its the shareware version and i have the retail version.

it says your memory bus is 147MHz, right? if this is the case then my first guess is that its regular non-parity RAM. ECC RAM generally does not like to be overclocked while in ECC mode. HOWEVER, this is not the rule but rather just a guess. so i wouldnt make a purchase based on that. i wonder, did you overclock your system? if not where did you get the system? is it home-built/custom? or is it from an OEM (Dell, Compaq, Gateway, etc)?

at this point, if i had a gun to my head and had to make a choice right now, i would say buy ECC RAM. PC150 ECC SDRAM if you can find it. otherwise some good quality ECC PC133. ECC ram will run just fine in non-parity mode. its when you try to introduce non-parity RAM into an ECC system (running in ECC mode) that things start to go wrong.

post as much information you know about your hardware first. we need to try and find out for sure whats going on inside the box first before you buy anything. if worse comes to worse, there may be a little buy-try-return-exchange going on until we get it right, but i would like to avoid that if at al possible.
