Prob with ram

Pearl Jammzz - Aug 23, 2002

			I just put in a 256 stick of ram in my comp. I had a 128 stick of it at first which was in the first slot. I took the 128 out and put that in the second slot then put the 256 in the first one. Started up my PC and everything is the same. it says I have 128. What's up?

			some bios's allow you to disable a ram-bank. maybe that's the problem, look for an option like that. if there's none try running your pc with the 256mb stick only in the slot in which you had the 128mb before. if it doesn't boot, you could try changing the settings for timing a.s.o.. it could be that your new stick only runs at 322 at 133MHz and ther old at 221 or something f.e. understand what i just tried to say?

			Kind of, I am gunna try bunches of shit. I have to work early tomorrow so no partying tonight so I have time. Post anymore ideas u guys have.....I'll check back in the morning.

		Link Hylia		Aug 23, 2002
			another more likely possibility, is the fact that the system can only handle 128 MBs of RAM per RAM bank i.e. put 2-128 MB sticks and you will have the max 256 MBS ram it can handle.

			Hmm, you should check on another computer, maybe the ram is defective. It happened to me with a 128mb stick.

		Pearl Jammzz		Aug 24, 2002
			Well it works now . I took out the 128, loaded everything up, then put the 128 back in and now I have like 380. Still no power house but for 20 dollars, I can't complain.

			Was it ddr?

		Link Hylia		Aug 24, 2002
			Double Data Rate, a type of RAM that does 2 things per cycle, instead of 1, Reads and writes twice per cycle instead of your Standard Synchronous Dymanic Random Access Memory, which writes once. and yes, it actually benchmarks around twice as fast it's only for newer motherboards that support AMD Athlon processors. P4 is getting it as well, since Rambus sucks.

			Performance is only doubled if you're doing nothing but burst reads, I think...

... i know what it is i'm asking if that's what he used. And wait... you need to be using an athalon? you can't use ddr ram if your using a p4.. aw shit man when i order my cpu i intended to get ddr ram sticks... damn, are you sure ddr won't work with p4?

Depends on the chipset. Some use Rambus, some use DDR.

			[homer]D'oh![/homer] misread Was as What and, yes Pentium chips are getting the DDR memory http://www.sharkyextreme.com/hardware/moth...cle.p...

		Pearl Jammzz		Aug 26, 2002
			it was sdram. I have a p3 650, obviously doesn't suppot it.

		Gallstaff		Aug 26, 2002
			good...cause i really wanted a p4 and ddram since sdram is crap (no offense bjammzz)

		Gear		Aug 28, 2002
			I always thought that rambus was part of the good side of the p4

If you're going to put DDR RAM into a PC, it is going to be SDRAM.

		Gallstaff		Aug 28, 2002
			that doesn't make sense...

		mal		Aug 29, 2002
			It does make sense. It may be Double Data Rate, but it's still SDRAM.

			TMA! Too Many Acronyms definitions of the Acronyms: DDR - Double Data Rate; type of RAM that reads/writes twice per cycle, in effect doubling effectiveness SDRAM - Synchronous Dynamic Random Access Memory; the kind of memory all PCs have been using for at least 10 years RDRAM - Rambus Dynamic Random Access Memory; speedy clock speed, but only a 16 bit data bus, meaning it has to wait 2 clock cycles for the data, slowing down the whole system. SDR - Single Data Rate; memory that Pentium 3, Celeron and earlier processors use. if you want Single Data Rate Memory: SDR RAM Double Data Rate Memory: DDR RAM (to distinguish from Dance Dance Revolution)
