Choosing/upgrading DDR memory

I am currently running my pc with 256MB DDR266MHz (PC2100) and 256MB DDR300MHz (PC2400), a total of 512MB.
Want to upgrade to 1GB, because XP runs pretty slow with 512MB. Do you think it would work with DDR333MHz (PC2700) or even with a higher rate of DDR400MHZ (PC3200)? Those two are far cheaper than PC2100 (PC2400 is not available here in NZ).

    My board supports up to 2GB. I think 1GB should be enough.

    Are you saying 1GB of the same speed that means 2x512MB PC2700 DDR333MHZ or 2x512MB PC3200 DDR40MHz. Is it right? What about 1x1GB and keeping one free slot/bank?

I have a Hp Pavilion 733b with chipset 845g, i have 1gb of ram but just recognise 256mb


Product: HP Pavilion 733b Desktop PC

http://h10025.www1.hp.com/ewfrf/wc/product?product=296502&lc=en&cc=us&dlc=en&lang=en&cc=us

Motherboard: FIC VG31

[ First International Computers ]

Motherboard specifications;

http://h10025.www1.hp.com/ewfrf/wc/document?docname=bph07722&tmp_task=prodinfoCategory&cc=us&dlc=en&lang=en&lc=en&product=296502

Memory Type: DDR Sdram
Memory Speed: DDR Sdram at 266MegaHertz, or 200MHz
(PC2100, and PC1600, respectively)

Memory Sockets: Two. For Dual Inline Memory Module/s.
Maximum Memory: -> Maximum TOTAL Amount for motherboard.
2GB.
Maximum Amount for EACH ram memory slot: 1GB

So far looks good, BUT;

1) Is the Ram Memory Non-ECC?

http://en.wikipedia.org/wiki/ECC_memory

2) Un-Buffered? (Un-Registered)

http://en.wikipedia.org/wiki/Unbuffered_memory

3) Voltage: Does it use 2.5 Volts?

JEDEC standard for DDR Sdram ram memory voltage is 2.5 Volts (DC)
FIC is going to set the ram memory default voltage at 2.5 Volts.

Point? DDR Sdram at 2.6 Volts, or higher, may not work.
Betting the motherboard doesn't have SPD, and the ram memory may not either.

http://en.wikipedia.org/wiki/Serial_presence_detect

4) Ram Memory frequency rate:
What frequency rate of ram memory are you using?
(Excuse me,...'Speed')

The Intel 82845G Northbridge chip, will only support DDR Sdram at a -> Maximum <- frequency rate, of 266Megahertz. (266MHz),

http://en.wikipedia.org/wiki/List_of_Intel_chipsets#Pentium_4_chipsets

I have seen websites offering DDR Sdram at 400MHz for this board.
Maybe there is a BIOS update, I don't know. But going with the standard BIOS program that is installed, and info for the Intel 845G support, I would say this = No.

Processor Front Side Bus (FSB) support is either 400MHz, or 533MHz.
Ram memory typically operates at HALF of the Processor's FSB.

That would be 200MHz (PC1600), or 266MHz (PC2100), respectively.

[Half of 533 = 266.5
It's just rounded down to 266 ]

Can you read a manufacturer's label on the ram memory modules?
If so post what you see in a Comment.

Regards,

[Sometimes when upgrading ram memory, it may take you to turn the computer completely off, and wait 1 minute. Then turn it on, and let it run for a couple of minutes, then turn it off. Wait 1 minute, turn it back on.

IF, the motherboard does have SPD, and IF, the Ram Memory has SPD, it may take a couple of 'Cold Boots', for BIOS to recognize the Ram Memory.

Some of the old mobo's were just like that.

My asus p4ge-mx-uaykz motherboard has two slots for installing ram right now i am using 256mb can i upgrade it to 2gb?


Yes you can upgrade to any DDR that is rated at PC2700/PC2100/PC1600 and non ECC. Up to 2 gigabytes.

I had just one memory module on this motherboard which was kingston ddr, 256mb, pc2100. Then i upgraded my mobo with one stick of pc3200 ddr ram, and it keeps restarting and sometimes it just turns off...


PC 3200 is not supported by this motherboard. It will cause problems. You need to use PC2100 RAM.

Hope this helps.

PC Motherboard Memory upgrade


From Asus tech: Memory 3 184-pin DIMM slots for PC1600/PC2100 DDR SDRAM
Supports up to 2GB memory
No ECC supportThis is only compatible RAM so make sure your new chip is PC1600 or PC2100. If you mis the 2 it the faster RAM will run at the slower chip speed. Hope this helps.

2 x 1GB Samsung PC2100 appearing as just 1GB (2 X 512MB)


Hi Patrick,
I see you're point. I know this, you can not run "more than" 512MB in any DIMM slot. That is shown at the bottom of page 10 & the top of page 11. You can not run both types of memory at the same time, even though the chart looks like you could. The description term on page 10, states; Users only can install either 168-pin SDRAM Module or 184-pin DDR DRAM Module at one time. (You can't run both). You can run 4x512MB in all banks using184-pin DDR SDRAM. Or you can run 4x512MB in all banks of 168-pin SDRAMs. Total of 2GB.
So you can not run 1GB of memory in any bank.

Asrock K7VM2 Motherboard Memory Upgrade


Some MOBO support different type of memory modules like ddr 400, 333,533 and other, if your computer is working fine with that PC400 it only means that your MOBO is compatible with it. Since you're planning to upgrade the memory just get another PC400 because the memory should be the same to work fine.

Intel D845GBV Motherboard Problem


PC1600 runs at 200MHZ and PC2100 runs at 266MHZ..

Since your motherboard only supports a max of 266MHZ, I would recommend that. (not to mention that PC1600 is pretty much obsolete)..

2nd, you motherboard supports a MAX of 2GB Total ram.. So, you could install 1GB + 256MB.. But why not go for 2xGB?

The price for a 1GB stick of PC2100 is around $75-125 CAN. Not soo cheap anymore...

DDR & SDRAM supported?


I suggest you stay within your manual specs.
Your boards memory should not use voltage higher than CL2.5
Below is a link for 1Gb dimm DDR266 PC2100. CL2.5
http://www.zipzoomfly.com/jsp/ProductDetail.jsp?ProductCode=80388-1
You can also buy two which would take you to the motherboards MAX memory of 2Gb.
