Re: memory installation

Check your manual pg. 11 section 2.5. The 168-pin RAM go in the black slots ONLY. The 184-pin RAM goes in the blue slots only. Worth a check! Luck.

System reguirements to inrease ram memory

Ram Memory typically operates at half of the frequency rate, ('Speed'), that the Processor's -> FSB does.

Your motherboard supports Processors that have either a 400MegaHertz Front Side Bus, (400MHz FSB), or 533MHz FSB, or 800MHz FSB.

(Northwood Core for 400MHz FSB. The rest is in the other solution I provided)

Processor has a 400MHz FSB?
You can use DDR Sdram ram memory that is 266MHz.

Processor has a 533MHz FSB?
You can use DDR Sdram ram memory that is either 266MHz, Or 333MHz.
(PC2100 and PC2700 respectively)

Processor has an 800MHz FSB?
You can use DDR Sdram that is either 266MHz, or 333Mhz, or 400Mhz.
(PC2100, PC2700, and PC3200, respectively)

When using a processor that has an 800MHz FSB, and using PC2700, (DDR at 333MHz), the PC2700 ram memory will run at ->

JEDEC has set the voltage requirements for DDR Sdram at 2.5 Volts.
'Performance' ram memory that is DDR Sdram may use higher voltages.
Not recommended unless you know how to overclock.

Although the motherboard, and the ram memory module may have SPD, it doesn't always work,

A lot of times you are faced with going into BIOS Setup, and changing the ram memory voltage, IF BIOS Setup has this feature.
This is why I say overclocking experience helps tremendously.

You want Low Density, Unbuffered, Non-ECC, and a CL of 2.5 for PC2700, and a CL of 3.0, (3) for PC3200.

[Why would anyone want to run PC2100> Lol! ]

Hello Folks, I'm in dire need of help. Nowadays

Hi Joseph.

The Asrock motherboard has 2 memory banks each supporting 1GB PC2100 (DDR266) / PC2700 (DDR333) memory modules (2GB) in total.

I would recommend that you purchase the PC2700 (DDR333) memory because its a little faster than PC2100

The HP memory that you posted a link to will not work as it runs at 400MHz (PC3200) which is too fast and the motherboard doesn't support memory that runs that fast and is the same with the other link too. In both cases you are paying through the nose as you can get DDR ram much cheaper than $118 dollars.

I would recommend to you Kingston Valueram. It is much cheaper and runs very well. You can also get this RAM at Walmart!! It cost around 45 dollars which is a saving of over 80 dollars.

Right click on the link I have provided for you below and open it in a new tab or window, you will nicely surprised at what you see

Good luck and if there is anything else please post back.

I want to extend the RAM memory on my NEC computer. The motherboard is a GA-8SIMLNF Rev.1.1. It has two memory slots and presently one slot is occupied with a PC2100U-20330-A1 256 DDR 133 CL2 memory. I...

Check your manual (Gigabyte will have the manual on their website), to make sure your motherboard can handle 1Gb of Ram, or more. Generally in my experience, medium aged motherboards handle 1GB per slot, max (mine uses PC3200, not PC2100, and will take up to 4GB in its 4 slots).

You'll want PC2100 ram (easily searched for on, either in 2x512MB sticks, or a single 1GB stick for your open slots (bringing you up to 1.25GB).

Power on ok but no display. ram not detect

First disable the onboard VGA then put in a known good AGP graphics card to see if you can get through the POST if your BIOS i rejects the RAM chips it should give you a short series of beeps this would indicate that the memory is not compatible as a rule of thumb PC2700 speed memory is for a motherboard and processor with a 133Mhz FSB this is quaded to 533MHz. you can usually place faster memory but not slower memory look at the table below for rated Frontside Bus Speeds.

CPU FSB DDR DIMM Type Memory Frequency
800 MHz PC3200/PC2700*/PC2100 400/333*/266 MHz (min busspeed 200Mhz)
533 MHz PC2700/PC2100 333/266 MHz (min busspeed 133Mhz)
400 MHz PC2100 266 MHz (min busspeed 100Mhz)

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.

Install DDR-DIMM PC3200 to MS-6367 MSI

That motherboard was made for PC2100 DDR266. A PC3200 DIMM *SHOULD* be backward compatible. Depending on the density of the PC3200 memory you might have problems. If you have not bought the memory yet I would go with the PC2100 for sure since the PC3200 will give you no speed gains at all and will be running at PC2100 speeds anyway.

If you already have the PC3200 memory then I would say just give it a shot. The worse case scenario is your machine will not boot up with the higher speed ram installed. Assuming you take all the normal hardware upgrade care and do not physically break anything you can test this memory with no harm to your motherboard.

I think I have the wrong memory installed.

You shouldn't see any problems as your computer supports up to PC3200. Basically it is backward compatible so your computer will support PC3200 and all the lower numbers, such as PC2700 and PC2100.

its a case of purchasing the new ram modules taking the old ram out and popping the new ram in

i wud recommend using OCZ, GEIL or Crucial memory modules as these are the best makes

the spped of the ram varies from system to system depending on the system bus speed
the most common speeds for this board is pc2100, pc2700 and pc3200
these speeds are as follows pc2100 - ddr200
pc2700 - ddr333 and pc3200 - ddr400

hope this helps

Ddr ram for my motherboard

PC2100 is DDR266 memory. PC2700 is DDR333 memory. PC3200 is DDR400 memory All are backward-compatible with PC2100. Memory is designed to be backwards compatible, so generally you can safely add faster memory to a computer designed to run slower memory, but... your system will operate at the speed of the slowest memory module or system component. Keep in mind that the memory does need to be the same type, for example, SDRAM cannot be mixed with DDR, and DDR cannot be mixed with DDR2. ZT3000 "Beta tester of "0"s and "1's"
