Question about Sony VAIO RB30C (VGCRB30) PC Desktop

1 Answer

Just curious Hi, Why can't one use just two 1gb chips? Wouldn't the 1gb chips have two 512mb chips ganged together, or aren't the slots in line? I was going to do the same thing after getting a friend's old RB30C. Thanks. Your previous answer : If it has 4 slots and supports 2Gb max with 2 slots currently populated with 2 x 256mb chips you'll need to remove both those chips and install 4 x 512mb chips to reach the max of 2 Gb.

Emachines T5082 Adding 512Mb ram. Getting slot 0 installed slot 1 not installed.


Try swapping the memory in the two slots. It sounds like either one of the memory chips is bad or one of the memory slots is bad.
If you find that one of the slots is bad, then you might try just putting a 1GB Chip in the slot that works.

214-Dimm Config Warning


Just had same problem. Found a solution:
I have an old HP Compaq dc5000MT. It has 4 RAM slots
Here's what DIDN'T work:
1gb + 1gb + 512mb + 512mb
1gb + 512mb + 512mb + 1gb
512mb + 1gb + 1gb + 512mb
Here's what DID work:
1gb + 512mb + 1gb + 512mb
I'm sure that:
512mb + 1gb + 512mb + 1gb would probably work as well.
From my guess they're are 2 "channels" (slots 1&2 are channel 1, slots 3&4 are channel 2) and you have to keep the amount of RAM balanced on both slots and in the same order.
Another thing to note with the old XP OS. IT ONLY WORKS WITH 3GB or RAM. MAX. So 1 + 1 + 1 + 1 (4gb) WILL NOT WORK... PERIOD for XP. Vista, 7, 8 etc. allows you to use a ton more ram + readyboost. They need all the help they can get though since they are major resource hogs.

New ram memory on dell dimension celeron trying to


You should check with the folks at Dell since whoever wrote their technical manuals for this machine can't do basic math. There are 2 memory slots and each can handle a maximum capacity of 512MB, yet they claim the maximum capacity for the machine is 2GB instead of 1GB. Using 512MB modules would probably work.

Can I add 1GB memory chip in 2nd slot with a 512MB chip in 1st?


You can upgrade by inserting a 1GB PC2100 DDR SDRAM DIMM. I would put the 1MB in the first slot and move the 512MB chip to the second slot.
The 1GB should cost around $40.

Compatability of Memory Upgrade


DDR RAM needs to be installed in pairs, as in if you have two 1GB sticks these would, in a four slot board, be inserted in slots 1 and 3 or 2 and 4. The other odd 512MB stick could go in any other slot theoretically speaking. But, you would be better off leaving it out. The SPD chips on the two 1GB sticks should match themselves to time at the slowest common or fastest common denominator.

There is a chance that by having the odd bank population that you said worked for awhile installed as you had, that the MB RAM slots were put under unusual voltage stess. There is a pretty good chance you can remove the 512MB stick, leave the two 1GB sticks in slots 1 and 3 or 2 and 4. But, this is VERY important: consult your board manual or access it online and read what the population requirments are for the slots as in some cases, the two matched sticks go in 1 and 2 or 3 and 4. This little oddity is found from time to time.

Consult your manual or download it and read how the slots need to be populated and stick with the two 1GB sticks.

There are memory testing programs you can find for free at majorgeeks dot com and test your RAM once you have it populated correctly.

In the future, I'd suggest you purchase RAM from Kingston or Corsair directly online as they usually offer a lifetime warranty and this RAM right now for you board is dirt cheap.

Hope this FIXED, as in ANSWERED you question and was more than helpful. Should you feel compelled to rate this solution after reading, either rate it FIXED or not at all. I know its helpful by default, that's what we do here. But only a thorough answer can FIX your situation. You should be fine if you follow my instructions. But, please consult you manual.

Memory installation


It really should be able to. The only thing I can think of would be that the board just feels like being picky about what you put in it. Wait... are the chips all the same speed? If not put the slower ones in pair 1 (which I guess is purple) and the higher speed in pair 2. If you have it the other way, sometimes the system won't even out the speeds for all the chips and one chip (or in this case, pair of chips) will overheat because the board forces it to run faster than it should. But if that doesn't work, I really have no choice but to admit defeat, because unless the board is bad (which it isn't, since if you take one pair out, it works) it makes no sense.
