New ram screwed up old ram. Help.?

Question

I tried adding 2 new 512 sticks to the 2 512 sticks of ram I already had. The Newegg website said that it would be compatible, but after I put it in it totally screwed with my computer, and it was not booting at all. I got it to read one of the two original 512 sticks, but now I am at 512 MB instead of a gig like with both sticks.
Help please.
The new ram would not work at all, and I was messing around with the different slots, and it seems that the two older sticks that came with the computer will both work in the fourth slot, but not the first second or third slot. I have some new ram coming in the mail, but if it is the sockets themselves with the problem, will I just need to get a single stick that is a gig? My computer can handle four gigs, so could I put a two gig stick in one of the four slots, the one that is working well?
I had a tech look at it, and he got the two old sticks working in 3 and 4, and it worked but when I came home yesterday, it was back down to 512????

Try cleaning the memory slots with a small paint brush. Then clean the contact pins of the RAM modules w/ the eraser at the end of a pencil. Then test each module (one at a time) at DIMM-0, the one closest to the processor. The module that does not work there could be defective or incompatible with your motherboard.

I doubt that to procure the incorrect style of RAM on your board because of the fact the pins on DDR and DDR2 are thoroughly diverse, and neither will slot in the different's DIMMs. First, make advantageous your connections are all appropriate and there is no airborne dirt and mud or something, and additionally that the RAM is in the the basically right option DIMM slots. I even have heard that RAM working at unsuitable voltages will reason instability. many times your pc can hit upon the right voltage quickly, yet whilst it would not, you are able to go forward and alter it your self in the BIOS. It varies a thank you to try this finding on your motherboard, so look for suggestion out of your handbook and additionally something that got here along with your RAM to confirm the right voltage settings. If that may not the case, you will possibly basically have a bad stick, which may additionally reason instability, so shop your evidence or purchase handy in the form your finding out shows the two shop on with be defective.

Depending on the motherboard you are using, while it supports upto 4gigs of system memory, you might have tried mixing dual channel and single channel memory together which won't work. Check the specification sheet for your system or motherboard to determine what type of memory is supported, usually listed as either 266mhz-400mhz, or, PC2100-PC3200 for DDR memory, or 400mhz-800mhz / PC3200-PC6400 for DDR2 memory. For optimal performance, remove the old memory completely and install two sticks of Dual Channel of the type of memory supported my your specs sheet, if you were shooting for 2gigs of system memory total, buy a matched set of (1024mgs x 2) dual channel memory sticks within the rated specs accepted by your machine. This will leave you 2 slots open for future upgrades later if you so choose.

Sell all your ram on eBay
