Is this micron ram really micron ram?

[sgoaty]

Im having problems getting my mates PC working. I posted about it before
http://forums.hexus.net/showthread.php?t=112794

I took the motherboard cpu and ram to a local pc shop so they could try out all the components. He managed to get it booting but not with my mates ram. The ram works in my pc but not his. I decided to check if the micron ram we bought was on the compatibility list but i cant see any mention of micron or nanya anywhere except the scan sticker. The chips all say SEITEC do micron use these chips and how do i find out what model the ram is?
thanks

Whats the code / markings on the DRAM chips? You can identify if it is Micron using this code.

Micron make their own RAM modules but also supply their DRAM chips to other companies, so you will find RAM using Micron DRAM chips that have not actually been assembled by Micron.

If the memory works in your pc then put it in your pc and run CPU-Z to check if it is Micron RAM. This will only show as Micron the module was made by them.

as nickp states, the key isnt do the pcbs say it, but do the actual chips say it? All micron ram chips will read micron on them, however, they aren't sold under the micron brand, Crucial is the module making arm of micron, who also sell the actual chips in bulk to other assemblers

A Micron chip will look like the one below. The two semi circles on either side of the chip will always be present on a Micron DRAM chip.

Not strictly true - Most have the "M" mark on them (Its an M with a circle around it), but some are only identifiable by the codes on the chip, annoyingly.

It depends on the type of RAM though. A lot of Micron DDR2 (all?) use the newer BGA type of chips. These certainly won't have the notches in them

I stand corrected, just had a quick glance at some in the bits box and it reads micron, although its some pretty old crucial stuff.

Forgot about the BGA type but still the Micron logo should be present and the code will verify if it is Micron or not.

Theres no logo or legible numbers its ddr2 by the way. Ill try it in my pc again when get a chance

I put it in and CPU-Z says nothing in the manufacturer box. Can anyone from Scan comment on this?

[nickp8]

Well it wont if the module wasnt manufactured by Micron, but is using Micron DRAM chips.

The only way really to identify if it is using Micron chips is by the code on the chips but you say there is none.

All i can make out on the chips is Seitec which from a quick google is another ram manufacturer. I cant get this ram to work with the motherboard but it says micron is on the compatibility list. I just wonder if there has ben a picking error and this was sent instead of the micron stuff i ordered. Can someone from scan please comment

[sgoaty]

Come on guys please help

[sgoaty]

it seems you guys no longer care about your customers guess ill shop elsewhere in future. Thanks for the good service in the past just a pity its changed

[nickp8]

Have you actually contacted Scan about this or sent a private message to one of their staff informing them about your post?

Just ring them, its much quicker.
