Hi all,

I just tried to fit my new pc3200 1gb ddr400 ram stick and I get nothing at all when I turn my pc on?

when I put my 512 back in it works fine?

Do I need 2 sticks of 1gb to get it to work?Or am I doing something wrong?

Any help will be valued

Thx in advence

Howdy:

Is the new ram compatible with your system??

What is the motherboard make and model of your system??

Hi again Murray,

I checked my bios and it is set at the following, could this be the problem??

cpu speed = manual
cpu freq multiple = 18x
cpu external mem mhz =133
cpu mem freq ratio = auto

Am running a p4 2.4 cpu at the moment but hope to have a p4 3.00 in the next couple of days.

Could be a square peg round hole problem. Although your memory is theoretically backwards compatable, Murray's questions were right on the money. That board supports PC1600 and PC2100 up to 2Gigs using three dimms slots. Now, you are the proud owner of a PC3200 module that appears to be incompatable with your board.

MMMM? I went to crucial.com and did their test and though 3200 wasnt what they recommened it said it was compatible with my motherboard?( see below)

If i just run another 512 2100 will that make a difference?

I only have 2 dimm slots on my motherboard not 3

Thx Chelsea,

These memory upgrade choices are guaranteed compatible with your ASUS P4B533-VM.

184-pin DIMM |

1GB CT12864Z40B DDR PC3200 • CL=3 • UNBUFFERED • NON-ECC • DDR400 • 2.6V • 128Meg x 64

do you have any other memory in the board? have you tried a different stick of pc3200? a different slot?
these are dum questions with obvious answers and sometimes great results. you definantly want pc3200 ram. i find that 2 sticks of 512 work well duel channel instead of one gig single. you dont have duel channel tho i dont think.

Sorry, you have 3 PCI slots & only 2 dimms.
Here's from the ASUS site re: your board.

Key Specification Summary

Supports Intel® Pentium® 4 socket 478 processors
Intel 845G and ICH4 chipset
2 x DIMMS slots for up to 2GB of PC2100/PC1600 DDR SDRAM support
1 x AGP 4X (1.5V only)
2 x UltraDMA/100/66/33
6 x USB 2.0 ports
3 PCI slots
C-Media CMI-8738 MX 6-channel audio (optional)
Intel® 82562ET PHY (optional)
ATX form factor

You may have a shot at getting this memory to run but I wouldn't bet the bank on it. If you can ever get into the BIOS (I know you haven't been able to get any kind of post yet) you can try resetting this memory to auto or have a go at manually setting your timings. This is probably going to be a stretch and more than likely, you're stuck with a square peg and a round hole.

As to your Crucial page - my bet is this isn't the module you bought. Is your stick 128x64 or do you have a higher density module from a different manufacturer?

Here's a bit more re: spec summary.

Good Luck
