Ebuyer unbranded memory doesn't work - how do I even know I have the right stick?
"Jonathan" wrote in message ups.com... SNIP Hi, It is anything but unknown for ebuyer own brand memory to have a high DOA (dead on arrival rate). Often one or more sticks will be duff. I am not sure if you system demands matched pairs or pairs at all. But I would suggest just trying one 1gb stick at a time (i.e. literally just one of your new 1 GB ebuyer memory sticks). Try this with each stick to see if you can identify one as faulty. (Likewise, if you system does require matched pairs you can always see if you can borrow a known good stick form a friend and try one of yours with that, etc. - or vice versa [if the system requires matched pairs the likelihood of this working is going to be very low - also if your system does require matched pairs I would be surprised if that is what you are getting from ebuyer - they never used to do own brand matched pairs). Anyhow - hope that helps and good luck. Best wishes, News Reader P.s. Their is every likelihood that one or more of the sticks is faulty but it would be a shame if it turns out that they are not. |

Ebuyer unbranded memory doesn't work - how do I even know I havethe right stick?
Jonathan wrote:
In my Medion 8083, there are 2 sticks of Samsung and 2 of Elixir memory, 256Mb each. 1Gb simply isn't enough these days, so I did lots of research, found various configurators and read this page: http://md8083.hertsinternet.com/memory.shtml which led me to believe that this product should suit: http://www.ebuyer.com/UK/product/63128 - bought 2x1GB DDR PC3200 400MHz 184pin non-ECC ram, exactly as should work, and as you can see from the other page, 1Gb sticks should work. [snip] On the front is a sticker with just the number 178873 and there are 8 chips marked 128xDDR, also the numbers 0710 400 on each chip. So, I'm guessing that'll be 400Mhz and 128*8 is 1024, so it looks sort of right. Apparently the motherboard in that PC has the Intel 865PE chipset. These only support chip densities up to 512mbit, so 8-chip 1GB sticks will not work. Those cheap 16-chip "high density" sticks they sell on eBay won't work either, but for a different reason. Branded 16-chip 1GB sticks should work fine, but these will be more expensive. -- John Jordan |

Ah - now that's a good answer, just not one I wanted to hear! OK - how do I find out whether a stick has 8 or 16 chips? All the crucial sticks say 128x64, so if each chip is 128Mb, then there can only be 1024Mb. I found the Crucial Scanner thing http://www.crucial.com/uk/systemscanner/index.asp but it only wanted to recommend Ballistix sticks, or kits with parts that ebuyer didn't have. Bearing in mind the memory is going to have to go back to ebuyer, can you please let me know what to search on? I used the memory finder tool at http://www.crucial.com/uk/store/list...x?model=MD8083 which recommended a CT434183 stick, but ebuyer don't have that part. There's this, though: http://www.ebuyer.com/UK/product/65719/rb/0 - but again, it doesn't say how many chips, just that it's called CRUCIAL 1GB DDR PC3200 400MHz 184-PIN UNBUFF 128MX64 Memory Sigh. This business with 8-chip and high-density non-working chips is a whole new world to me. I foolishly thought that one thing called a 1GB DDR PC3200 400MHz 184pin non-ECC stick of RAM would be the same as another stick of RAM with the same name. |

They must have hated you, often they (used to?) cross ship (i.e. the new goes out before the old gets back), although they may need a CC number for that. But yeah, for the benefit of the OP, buy RAM from Crucial. Not sure exactly WHAT I'd recommend buying from ebuyer - something that can't go wrong, I guess .. carpet tiles, maybe. -- GSV Three Minds in a Can 8,963 Km walked. 1,746Km PROWs surveyed. 31.7% complete. |

I recently bought the recommended memory for a Shuttle SN41G2 from Crucial using the selector. It looks to be the same spec as above. Whilst it worked fine I had the reassurance of the guarantee. Downside is it cost £98. I'm sure with more research I'd could have purchased suitable RAM for less than £50. I'm still trying to convince myself it was worth paying double for the no quibble guarantee. |

Well when you're building systems, you only need to build a handful and have all the problems generic RAM from Scan/Aria/et al seem to always have and you'll buy Crucial every time. Generic RAM either doesn't work or fails within 12-18 months - most of that is because the cheaper stuff uses chips recovered from faulty DIMMS in manufacture. Crucial RAM is NOT that much more than generic. It's certainly within a couple of quid and if you're just buying RAM, then the lack of a £6.95 +VAT postage charge makes it cheaper. I have yet in 8 years of commercial building to have any problems with Crucial RAM whatsoever. For me, that's worth the extra money. -- Conor Light travels faster than sound.

Unless you buy through their memory advisor, there's no guarantee that the sticks will have the right chip density. I'd be surprised if any of their 1GB DDR sticks weren't 16-chip as they tend to use low-density chips for compatibility, but it's not definite. There's a related issue where memory controllers will often run better with 8-chip (single sided) sticks, but with Crucial you have no way of knowing what you're going to get. Some other manufacturers such as Kingston will specify more precise details for sticks if you know what you're looking for. -- John Jordan |
