plz help me with this SDRAM

[athlet]

i bought a 128MB SDRAM and its running with 100MhZ, no problems and my dealer said its a PC100 7-8ns. Today i tested the RAMs with SiSoft-Sandra and it tells me the RAMS are 10ns! So did he sell me some **** ? I heard there is a programm calles DIMM ID, but i cant find it.

The RAM:

VM 8M8-----7x4099 (thats everything, and i cant find out who VM is .. the 7 indicates 7ns, but maybe thats sth. else)

TCM (very very small) is also written somewhere else on the RAMs


thx

If its 10ns you have been taken... download the program at www.maximumpc.com (http://www.maximumpc.com) it should be laying around the site... I have the program on a CD so if you can't find it i'll send it to ya.

You are catching on to the marketing of ram! There was an article a while back on this, not sure where I saw it. At the time (6 months ago tops) there was ram around that said 8 on it and many assumed it was 8 nanosecond ram, but it's just a production code.

[athlet]

ok i downloaded DIMM ID and it tells me:

'Only works with Intel PIIX4. YOu will see this message if thePIIX4 is not found.'

If the RAM is 10ns how can i prove it to my dealer and get another one?

[Pantion]

Check the ram manufacturer and then go to its website and check the number. They have the codes there and the complete and TRUE specs of all the ram sticks they produce.

Try downloading other programs maybe SiSoft could be wrong.

thx for your help so far, but the problem is i CANT identify the manufacturer of my RAM. The only thing that looks like a logo or sth. is the big VM (about twice as big as the rest) that stands next to the rest (8M8----7x4099). TCM is also written somewhere else (very very small, and not on the chips but on the "dunno the english word for it, sorry").

So is there any chance to identify the RAM?


Is there another program that lets you identify the speed of your SDRAM except Sandra and DIMM ID?

i tried really hard .. but i cant find out who VM is .. plz help me

Possibly Viking memory try www.vikingcomponents.com (http://www.vikingcomponents.com) Good Luck

I had that thought also about the Viking Memory, but you may have to e-mail them to find what the specs are on their chips.

[topflite51]

Just went there, none of their PC66's nor PC100's start with 8M8 - back to the drawing board.

[athlet]

i just read that all PC66/100's start with

PCxabcxyz

sth. like that where the first x is 66/100 ... mine does not, does that mean it is not pc100 ? i'm getting a bit confused now ... and is there a chance to find out the speed of my ram via software (except sandra and dimm id) ... if my dealer sold me some 10ns i will go there and beat the s**t out of him /forum/smile.gif

What module are you reading in SiSoft that gives you the speed of your memory?

[Alzarius]

Make sure you have the latest update to Sandra. When I updated to the latest, the memory info changed to more correctly identify my memory. Even pulled off PNY from the chip. Which I already knew, but nice to see. I can't tell you how to definately get the correct speed of your memory, but i can say this. If you absolutely want to be sure the next time, you really need to buy name brand memory from a well known company. There are some generic components I don't mind buying, but generic memory is a toss of the dice every single time. There's so many scam companies, remarked memory chips and resellers who flat out lie to make more money off unsuspecting customers that it just isn't worth the savings if you get screwed. Also, buying memory that's in a sealed box(i.e. my PNY memory came in a nice sealed box) helps. Most of these generic chips are just literally handed to you by the stick which is really a dang poor way to handle something as delicate as a memory chip.

What setting do you have your ram set to under your cmos setup (bios)? If its set to 10ns, then even 8ns ram will be recognized and ran as 10ns. Programs like SiSoft don't actually query the chip, but passes along the value that the chipset believes the mem chips operate at. Just a thought, hope it helps.

Does it? when I did it before, i got diff. NS ratings for 2 sticks of RAM at the same time. If that was true, then it would show the same value across the board...
Also, I cant seem to find that module anymore!
It USTA be there
I got a junkload of new hardware..might be that...
Or maybe just new version of sandra dont have it..
I wonder..

[athlet]

thx again.

i have the Gigabyte 7IX (Athlon) and there is no option to set the speed of your SDRAM in the BIOS, i can just adjust some really weird looking settings and indeed i did a bit tweaking there so my Memory-Performance increased by about 5%. Maybe i should try Autodetect and just run Sandra again.

To Auraedge: yes you are right. I should have spent a few bucks more to get some quality RAM but i just bought the cheapest.
