Windows XP not starting after extra RAM added
Bought a new PC in January.
Specs a Windows XP Pro SP3 Gigabyte mobo (GA-EP45T-UD3R) with 4 slots (2 channels) for DDR3 RAM. I bought the PC with 2 x 1Gb Corsair DDR3 1333 MHz RAM. I have now bought 2 more of exactly the same Corsair RAM. After installing the extra RAM, Windows will not open fully. The PC only gets as far as the Windows XP screen and then goes blank. I even went into the BIOS but that froze after a short time as well. I have removed the extra RAM and all is good again. How can I get the extra RAM to work? regards PeterH |

It appears that it should be recognised automatically after installation. The only question mark is whether the Dual Channel Mode is automatically set or whether I have to do this manually. I tend to think it is automatically set, in which case why the problem. As I replied to Brian, there is a posting that seems to suggest that the voltage to the RAM needs to be manually reduced in order that the extra RAM (in 4 slots) is recognised. If I had installed the 4Gb of RAM in just 2 slots then it appears that the voltage does not have to be altered. I am going to check this out with my supplier's service department tomorrow and will reply if I have any luck. regards Benny |

How can I get the extra RAM to work? regards PeterH I agree with the other posters, that you should test the two new memory DIMMs separately, from the memory that you know is working well. For advice on "voltage", you can download a specification sheet for your Corsair product. Go to corsairmicro.com and try and locate the product. The package the memory came in, probably has the exact part number. This is just a guess on my part, as to what you bought (this is a 2x1GB DDR3-1333 kit). Corsair have many different kits, so I could easily select the wrong one. http://www.corsair.com/_datasheets/T...048-1333C9.pdf Nominal memory voltage for DDR3 is 1.5V. That is the value that JEDEC agreed to, for the DDR3 generation of RAM. To attain the higher speeds of enthusiast RAM, the voltage is *increased*. The value shown in that sheet is 1.7V . On page 40 of the motherboard manual, I see an entry "DRAM Voltage" [1.5} and "DRAM Termination" [0.75]. To start out, you'd expect the termination voltage to be midway, between supply and ground. I'd adjust that to "DRAM Voltage" [1.70V] "DRAM Termination" [0.85V] It is possible, whoever set up your system the first time, has already made that adjustment. They may have downloaded the datasheet for the first two sticks, when the first two sticks were purchased. And got the "DRAM Voltage" number from there. When extra memory is added, you would *not* reduce that setting. You see the recommended value in the spec sheet, and that is the voltage that Corsair chose, for their memory testing at the factory. If you drop the voltage, you'd have to slack off on the timing settings in order to keep the memory stable. Or even operate it at a lower speed. Since the memory in that example, uses a "JEDEC standard" SPD, that means none of the several extensions to JEDEC, are being used to control the automatic setup of the memory. JEDEC doesn't have a way of setting the voltage automatically. When using enthusiast memory, it is the responsibility of the user/builder, to set the voltage appropriately. If you've actually *mixed* two sets of products in the same computer, they should have something close to the same voltage requirements. For example, installing a 1.5V product and a 2.1V product, and then expecting to find a "sweet spot" for the result, is asking for trouble. Sometimes, a low voltage is stated, because the memory is known to "burn up" at high voltage. My previous computer used low voltage memory, and I would never consider cranking it to really high values. To get an understanding, for the unstated characteristics of the memory, you have to check forums or enthusiast sites, or the Newegg reviews, to get some idea what the stuff is. So, I think you have the wrong idea about voltage. This is a summary. 1) JEDEC set the voltage to 1.5V . JEDEC also designated standard speeds. 2) The memory industry always tries to surpass what JEDEC says. They try to run the memory at higher speeds. And that means increasing the voltage, to make it stable. 3) The voltage spec in the data sheet can mean two things. It can mean "hey, it was stable at 1.7V, and it'll take a lot more" or it could mean "ooh, if you use more than 1.7V, it'll burn up". A dash of common sense, and/or luck, is needed to interpret exactly what they mean. (They're hardly likely to admit the stuff burns up at high voltage. Some memory companies would rather be smothered in warranty claims, than admit to anything.) The first reviewer comment he http://www.newegg.com/Product/Produc...82E16820145183 Panzerfinder15 Great for price, fast, no complaints 6/6/2009 12:59:43 PM Cons: none whatsoever, other than they updated their sticks between January and now (run different voltages) I'm running all four at the higher of the 2 V ratings, and they are stable. (they run lower voltage now 1.6v vs. 1.75v, i think) So it is possible for a product to change specs, between buying two different pairs. Normally, you'd hope the spec sheet would track this, but again, marketing being what it is, they may change the product, and only "tech support" knows the secret. Tech support may say "is that Version 2 or Version 3" of the module. And that may be the first inkling you get, they've been screwing around. Corsair have forums, so you can check in there and ask questions. Be prepared to verify the exact part number on both pairs, since it is possible there is a subtle difference between them. If they change chip types (which you cannot see because of the stupid heat spreaders), then it is possible taming them will be more complicated. They may even suggest returning them, and replacing them with something else. http://forum.corsair.com/v3/index.php If they were mine, I'd test the two sticks separately, to see first of all, whether they can be tamed by themselves. Set them to the spec values shown on the product package. Test with memtest86+ and then boot into Windows and run Prime95. If the sticks don't work, send them back, and eat a restocking fee. Or whatever. Another way to handle the problem, would be to buy 2x2GB matched, and put the old ones safely in a drawer somewhere for a rainy day. I don't know all the tricks for DDR3, and there are sites which have tweaked those things to death. Try here for example. http://www.xtremesystems.org/forums/...y.php?s=&f=233 Another parameter to consider, would be "Command Rate". When using four sticks, or running sticks at extremely high speeds, that should be set to "2T". That increases setup time to rising clock edge. And I don't understand why the Gigabyte manual says the setting varies from 1-3. The choices should be 1 or 2. 1 is tight, 2 is slack and helps at higher speeds. Good luck, Paul |

I replaced one module of the old RAM with one module of the new RAM. No problems. PC booted all the way. 2. Replaced both the old modules with the 2 new modules. No problems. PC booted all the way. 3. Removed both modules from slots 1 and 3 (green slots) and inserted them into slots 2 and 4 (red slots). PC would not even start up. In fact it appeared to want to start then stop and restart again. I have tried to register with the Corsair site but so far they haven't emailed back to me so I can post questions. I have sent a query to Gigabyte so will wait to hear from them as well. I will also contact my supplier's service section today and see what they say. Is it possible there is a setting in Bios that needs to be changed so Slots 2 and 4 are operational? regards Benny |

"Benny" wrote in message ... Bought a new PC in January. Specs a Windows XP Pro SP3 Gigabyte mobo (GA-EP45T-UD3R) with 4 slots (2 channels) for DDR3 RAM. I bought the PC with 2 x 1Gb Corsair DDR3 1333 MHz RAM. I have now bought 2 more of exactly the same Corsair RAM. After installing the extra RAM, Windows will not open fully. The PC only gets as far as the Windows XP screen and then goes blank. I even went into the BIOS but that froze after a short time as well. I have removed the extra RAM and all is good again. How can I get the extra RAM to work? regards PeterH Hi All Thanks for the replies and details provided. I have tried swaping the old RAM with new RAM and get the follong results. 1. I replaced one module of the old RAM with one module of the new RAM. No problems. PC booted all the way. 2. Replaced both the old modules with the 2 new modules. No problems. PC booted all the way. 3. Removed both modules from slots 1 and 3 (green slots) and inserted them into slots 2 and 4 (red slots). PC would not even start up. In fact it appeared to want to start then stop and restart again. I have tried to register with the Corsair site but so far they haven't emailed back to me so I can post questions. I have sent a query to Gigabyte so will wait to hear from them as well. I will also contact my supplier's service section today and see what they say. Is it possible there is a setting in Bios that needs to be changed so Slots 2 and 4 are operational? regards Benny |
