-- Just a quick question about RAM for a friend --


i recently passed over a 1Gb PC3200 RAM stick to a work mate as i was buying a new computer and just stripped the old one for parts, the sticked worked perfectly in two machines of mine however when he has installed it into his machine its not recognized, even when installed on its own. His PC can handle 3GB of RAM and its the same type and speed of RAM. he previously ran 2x 256mb Sticks

Just wondering if anyone has any ideas what the problem could be?

Would he have to adjust anything in the BIOS?

Thanks,
Steve

Not all RAM modules are made equal...incompatibility is common enough that knowledgeable users consider chipset, density, timings, voltage, etc. before assuming that a given RAM module ought to work in a system. Just having the same designated speed...is not enough.

Often it depends on who made the system/motherboard.

If you take a look at a motherboard manual, you will see that manufacturers even often recommend specific brands as having been proven to work with their product. To employ anything other than what is recommended..is not necessarily the kiss of death, but it's a gamble.

Hey,

checked with my mate and he says the 1Gb is not under the list of recommended makes to use from the motherboard manufacturers however it is the same as the 2x 256Mb sticks that currently work in the PC

what else can we check / try to get the 1Gb stick working?

Remove the two sticks currently installed...insert the new stick properly...try to boot.

I also normally have had no problems switching RAM between systems...but I have had experiences in the last two years that came down to RAM being "acceptable" in one board while being "unacceptable" in another.

Additionally, some systems will work with low-density modules while they won't work with high-density modules (which is one reason high-density modules historically were cheaper).

No. Try not. Do... or do not. There is no try.

PC does not boot!

Checked out the two websites....is there any visible difference between high and low density modules?


are the 256 sticks cas 2 or cas 3?


How do i find out?


Sorry guys RAM aint my thing, normally i buy, i insert, it works :thumbsup:

From one of the links I provided:

All low density 1GB modules are made with 16 chips (8 chips on each side) using 64Mx8 device.
All high density 1GB modules are made with 16 chips (8 chips on each side) using 128Mx4 device.

The module should indicate whether 64x8 or 128x4 chips are used. I can clearly see the markings on some RAM modules, indicating what chips are used, on others I would have to look up the individual codes and/or guess.

The time to emphasize the distinction...is before buying, I've never thought to check afterwards.

you need to take the "pray" out of plug and pray

Would he have to adjust anything in the BIOS?


check in his bios and see if there's any setting for cas levels

your one gig is probably cas 3, his 256's are probably cas 2.5 or cas 2, which is faster!

Do you get any sort of beep codes when the system tries to boot with the odd ram?

You can also try resetting the CMOS. To do this, pull out the button cell that looks like this:

Wait 10 minutes and reinstall the cell. When the system turns on, set the clock. That should take care of ya!

Long time for an update but here goes....

CAS Latency in bios goes up to 2.5

the 1gb stick im guessing is CL3 ???

is this a basic its not going to work ?

Motherboard is ASUS A7V8X

OK!

apparently my mates changed the bios to cas3 and its still not picking up the 1Gb stick

told him just to buy a new stick and im going to put it down to a faulty stick at least

Cheers to everyone for their inputs!
