Failure to boot up

I failed to re-insert a 256mb PC2100 DDR Dimm into its slot correctly. The computer booted up the first time but with obvious consequences. I presumed I had burnt out the slot and moved the memory to another slot. The computer booted up fine the first time but then refused to boot up again. Moved the memory to the third and final slot only to have the same rigmoral. I have replaced the memory but the computer booted up the first time and now won't boot up at all. Same situation every time - can hear it powering up but it never actually boots up with nothing on screen. Wondering if I've burnt the processer out or what else would allow you to boot up first time but not second time?

If that ram you inserted is just an additional to your existing memory, then chances are that you have damaged the newly inserted ram. if that is the only ram you are using and you thought maybe inserted it incorrectly, it should not have worked even for a while. moving it from one slot to another and the same thing happens? i think your memory should be ok but you better check your mainboard now. otherwise check also the memory you got, what is the operating voltage. see if you're ramo is compatible with your board.

I wish to add RAM in the PC. Mine motherboard-Epox-EP-4BDA533(I). ID(identification)-05/09/2003-i845d-6A69VPA8C-00. On it costs RAM 256Mb -DDR PC2100 266Mg FSB-400Mg. How many Mb it is possible to add....



Manufacturer Specifications - EPoX EP-4BDA533I Number of Slots:
Slot 1
Slot 2
Each memory slot can hold DDR PC2700,DDR PC3200 with a maximum of 1GB per slot.*
*Not to exceed manufacturer supported memory.
  • 184-pin DIMM Banking: 2 (2 banks of 1)
  • Chipset: Intel 845D
  • Error Detection Support: ECC and non-ECC
  • Graphics Support: AGP 4X
  • Max Component Density: 512Mb
  • Max Unbuffered DDR SDRAM: 2048MB
  • Module Types Supported: Unbuffered only
  • Supported DRAM Types: DDR SDRAM only
  • USB Support: 1.x Compliant
Q: What memory goes into my computer, and will a faster speed be backward-compatible?
A: DDR memory with support for DDR PC2700,DDR PC3200 speeds.
Because DDR memory is backward-compatible, you can safely upgrade your system with any of the guaranteed-compatible DDR speeds listed below, even if your manual calls for PC1600 or PC2100 speeds.
Q: How much memory can my computer handle?
A: 2048MB.
Adding the maximum amount of memory will improve performance and help extend the useful life of your system as you run increasingly demanding software applications in the future.
Q: Do I have to install matching pairs?
A: No.
No, you can install modules one at a time, and you can mix different densities of modules in your computer. But if your computer supports dual-channel memory configurations, you should install in identical pairs (preferably in kits) for optimal performance.
Q: Does my computer support dual-channel memory?
A: No.
Your system does not support dual channel.
Q: Does my computer support ECC memory?
A: Yes.
Your system supports ECC. You can put non-ECC modules into an ECC system, but be sure not to mix ECC and non-ECC modules within a system. Install the same type of modules that are already in your system.

Sharp Actius AV18 does not recognize added 512MB PC2700 RAM. The machine still only sees 256MB. Is there something else I need to do?


I assume the laptop had originally 256Mb RAM and you put 512Mb RAM in a the spare memory slot and you expected to see 768Mb of memory, is this correct? Try removing the 256Mb memory module and insert the 512Mb memory module and see if the laptop boots up with 512Mb of RAM. If it doesn't boot up then the RAM is either incompatible or faulty. Try using RAM modules from the same manufacturer.

RAM compatibility with MK79G motherboard


Hi, I am assuming that the original piece of memory was a 256mb ddr pc2700/333mhz ?
i have looked at your board on the product maker website and it supports memory to 2gb of pc2100,pc2700/pc3200 type memory. Be certain however that the new piece added is the same clock speed as the original that you are trying to use with it. You cannot mix clock speeds, either pc will not boot or it will only recognise the compatible piece. Have you tried booting with just the new piece 9 leaving out the older piece)if yes what was the result. Need more help ?? compdoctor2005@btinternet.com

MEMORY UPGRADE FROM DDR 256Mb to DDR2 1GB hangs when Log on/Booting


Its a memory problem obviously. Try dusting the memory slot and try inserting the memory into the slot a couple of times. If still not working, the memory may be incompatible(rarely, there are brands of boards that doesn't suit to certain brands of memory), or it may be damaged.

Acer travelmate 2003lc will not boot with new ram


512MB (FT64MSD64V3F)
200 Pin Dimm - SDRAM - 2.5V - DDR - PC2700 (PC-333) - Non-ECC

is the correct type of RAM for your laptop.
Have you tried booting with all combinations.

512 in slot 1 --- Boots
move same dimm to slot 2 (on it's own) and try booting.
boot with 256mb in slot 1 and known to be good 512 in number 2

This laptop should allow up to 2GB RAM. So I don't belive it is an issue with the mother board not seeing the amout of RAM. I think it could either be flaky dimm or your slot 2 is damaged

Installing RAM in VPR Matrix 2250 Desktop


try one stick at a time ,as one may be bad,
also ensure you have them in the slot the correct way round ,as they will not seat down correctly if inserted wrong, take notice of the notch on both ram stick & ram slot.

good luck

Can't Install RAM in DDR2 and DDR3 DIMM slots


You cannot use DDR and DDR2 ram at the same time, because its always been like that (ie, no SD and DDR, or SD and RIMM)

What you should do is switch to all DDR2 sticks.
