Does anyone know if a "DDR PC2700 256mb" ram is combatible (or how to check) with a DDR3 and with these specs: (click to see it better)

Uh... IDK, mate... I suck at hardware stuff, or I would have helped you. Sorry. BTW, are you Italian?

your looking at this the wrong way..
I assume your upgrading your computer ram.
What you need to do is either look at the MB manual for specs for your motherboard or go to the manufactures website and lookup the specs for that motherboard.
That will tell you what memory stick design it supports as well as maximum amount it supports.. total and per slot.
this a requirement if your not just replacing the memory.

I discovered I have DDR3 ram. BTW, the ram "DDR PC2700 256mb" I said before, it cames from an old computer my father found beside the bins. We took what we thought could be useful. We took hard disk, ram and the CD slot (mine doesn't work). There was no graphic card.

DDR3 is different from DDR2,DDR,and SDRam and are not compatible with each other. DDR is from the late 90's to early 2000's before it was replaced by DDR2 in 2003. and there not compatible with each other do to different pin ammounts,layouts,difference in volts,and configuration. and forcing a ddr3 ram card into a slot meant for a DDR1 or SDRam could fry the ddr3 ram card do too to much voltage. and the DDR wouldn't work in a DDR3 ram slot do to not enough voltage.

heres an example for ya... Turns out that little RAM issue i had on ebay, where i did receive a set of 8G non EEC 2x4G sticks of ram, but it wouldn't fit in the intended computer .. Well the "new" HP i5 system i just bought yesterday, it does happen to fit in.. I thought xmas had come early, with my current 8G of ram and this non EEC ram, i would have an upgrade from 8G to 16G.. What luck would that be.. It turns out the damn computer wont boot up with the non EEC ram installed I haven't investigated it yet as to why this didn't work, but it may be due to nonEEC not being supported by the computer or the ram could be defective... just cause it fits the slots doesn't mean it will work. Even though all 4 sticks are 4G each,they even look the same, the computer has 4 slots for ram, its possible ( not really sure ) the computer may only support 8G max ram.. This is why you have to refer to the motherboard info to see what ram is supported.

actually tin the ram being defective could be the problem. becauses if you motherboard only supported 8GB of ram then the motherboard wouldn't use the other 8 or would tell you at bootup that it doesn't support said amount of ram. but no all the ram could be defective. so try out 1 ram card at a time in the computer to see which one defective.

I checked the BIOS info, no mention of NON-EEC and is DDR3 1333MHZ, if i remember the older ram is DDR2 PC-6400 800Mhz.
That's also a NO NO, mixing ram isn't a good idea even if it's supported,.. the really techy geeky guys will even try to buy all their ram sticks from the same production batch, just to get uniform performance.

TinSoldier : well the Bios isn't there to tell you of the limitations. the bios is basically the brains of the computer. you got look at the model of the motherboard which you can usually find it somewhere on the motherboard and look up the mother board model online.

dogtorque You've missed part of the conversation.. Your telling me to do exactly what i all ready said needed to be done in an earlier message in this thread... PS as to the BIOS, i have seen them list the ram type as part of the info supplied, but wasn't relying solely on it for limitations. I wont mix the ram types in any case, supported or not.. also even if this ram is defective, i got it for free from china and it took like 2 months to show up... there's no way in hell i would try to return it if defective.

To complete this story, the ram sticks were of a different style/speed. They were NON-EEC and thats what my i5 use's and it does support 16G of ram.
But the i5 supports 1333Mhz and one other 10** slower speed, but not the 800Mhz.
