    Ok, I have a AsRock 4CoreDual-Sata2 motherboard and an intel core 2 duo cpu running dual boot win-xp(32 bit) and vista (32 bit). I'm trying to use 2 x 2Gb of ddr2 667 ram (Kingston), I can only get 1 stick of ram to work at a time, both slots work, as do both ram sticks as they have been tried independantly. The motherboard bios has been updated, and the motherboard can support 4gb ram. I have only got it to work once till i reset my puter then it wouldn't start again,(BIOS POST tests dont start)

Depends on the motherboard and chipset mainly. Some chipsets/motherboards will not handle 4gb of ram. IF you're running Windows Vista 64-bit it has a serious problem with 4gb of ram and need updated manually before you can run it with 4gb of ram. Most other operating systems can handle it without updates.

Check dimms by booting up with each one in a dimm. If they all start, then it's a compatiblity error with either the operating system or possibly the chipset if the BIOS POST tests do not commence.

First need more info on your setup. your puter may not support 4gb. If it does do you have the right ram. Make sure ram is same type. If so take ram out & reseat it. Make sure to shut down & unplug power from back of computer. If this does not work try putting one stick in & start puter

Increase RAM to 4 mb for my Sony PCG-252L computer. Went to a another site this morning and they say the machine will support only 2 mb, 1 mb X 2. What is the truth?


I think you mean 4Gb instead of Mb...and you have 2 slots for your RAM...each supports up to 2Gb for a total of up to 4Gb...that's what the x 2 means...'times' or 'by' 2...you have to or should, increase both slots with the same amount of RAM at the same time...it will not support 4Gb in only 1 slot...Hope I helped!

Windows startup and memory issue


Many times Windows fails to startup and the RAM memory overflows:

This is a standard issue with all Windows based machines, some times this happens in other OS machines (Mac/Linux etc) also.

To solve this there is a very simple solution.

1 Switch off Power / Remove all power supply / remove all batteries
2 Remove the power supply cables
3 Press the Power On button on the machine for 2 - 3 minutes
4 Do ON - OFF for some time without POWER
5 Power back the machine and switch it on, the issue should be resolved now.

If Windows still fails to start then do this...next
If you can open the machine and loacte the RAMs
Remove all the RAM cards(a 1 inch by 4 inch circuit board with 4 or 8 ICSs fixed in it, some RAM cards are sealed so the ICSs cannot be seen) from the RAM slots and do the above process.
Fix the RAMs (it goes into the slot in one way only) in it's slot and clip back the RAM cards with a little click sound.
Put back the cover, attached the power and switch on

It should solve your issue now.

Installed 4GB upgrade in optiplex 330 still only 2GB memmory


Your BIOS should automatically detect your new RAM when your computer starts, try starting your computer after removing your old RAM module, if it starts, you need to update your BIOS to use 4GB. If it doesn't start, you either have a faulty RAM module or a faulty connector on your motherboard. Insert the new RAM module into the slot the old RAM module was in, if your computer still refuses to start, you have a faulty RAM module which should be returned, if it does start, it's the connector on the motherboard, and only replacing the entire board will fix the problem. However, it's worth noting that your motherboard will only support RAM modules of 2GB or less, the above was written with the assumption you're adding an additional 2GB module to your Dell computer.

I have a HP 7600dc Small Form pentium4HT 3.4 GHZ. it has 1GB of Ram with 4 slots whats the best, safest way to max out the RAM in this machine? What type of RAM do i need?


Memory Type: DDR2 PC2-5300, DDR2 (non-ECC)
Maximum Memory: 4GB
Slots: 4
Each memory slot can hold DDR2 PC2-5300 with a maximum of 1GB per slot.*
*Not to exceed manufacturer supported memory.
icon_note.gifAlthough the memory can be installed one module at a time, the best performance comes from using matched pairs of modules.When using PC2-5300 parts the maximum memory is 2GB. When using PC2-4200 the maximum is 4GB.

Hi there. I have an HP a6500f. Came pre-loaded with 4GB RAM. Worked fine for a year then started freezing/restarting/BSOD randomly. Ran memory diagnostics and got a BIOME-1 error with both sticks, but...


Try manually setting the ram timings in bios but....

i would think its a motherboard issue too by the sounds of it. find one that has a similar specification and fit it, I will suggest one if you need me to, just give me a list of the hardware you have installed on this current machine

RAM Upgrade


How much memory your Windows OS will recognize depends on which version of Windows you are running. 32-bit versions of Windows will see (and utilize) only 3GB or 3.5GB. To utilize more memory, install a 64-bit version of your OS. More information about OS memory maximums can be found at http://www.crucial.com/kb/answer.aspx?qid=4251

Not only is there a maximum amount of memory that your computer motherboard can accept, there is also a maximum amount of memory that your operating system (OS) can accept. For instance, when you install 4GB of memory in a 32-bit Windows system (the most common version; 64-bit systems are typically used by high-end users), your system reports only 3GB or 3.5GB.
First , we can assure you, there isn't a problem with the memory. While Windows allows for 4GB of memory to be addressed, it does not equate to 4GB of physical memory. Some of the memory (regardless of how much you have installed) is reserved for use by the devices that you are using, such as a graphics card, PCI card, integrated network connections, etc, meaning it is unavailable for use as normal main memory. Upon startup, your system calculates the amount of memory needed for these devices; if you haven't maxxed out the memory in your system, it's invisible to you, and all your physical memory (the installed RAM) is available for use. However if you've maxxed out the DRAM in your system, this amount will be deducted from your physical memory, so you can't use 100% of your DRAM. The maximum memory limitation varies by operating system, For instance, the 4GB memory limitation doesn't exist in 64-bit versions of Windows.
