Computer won't boot up after installing new RAM
Don't forget to use the Crucial on-line analyzer.
Can save you from getting the wrong stuff again! http://www.crucial.com/store/listmfgr.asp?cat=RAM As a cross check, to help in validating what you purchase, both the Crucial and Kingston memory for your PC should have very similar specifications. -- JS http://www.pagestart.com "Pool" wrote in message ... Hi JS and Paul Thank you so much for the valuable information you both gave me.I will get a new pair of RAM according to the specification you gave me before and i will get a new power supply because power supply fan is making loud noises.Thanks again for your help.

Kingston: http://www.kingston.com/hyperx/products/khx.asp#400d -- JS http://www.pagestart.com "Pool" wrote in message ... Hi JS Thank you for the information you gave me.I guess i got RAM that isn't working correctly.When i gave you Kingston model KVR800D2N6/1G it was the one i have in my other desktop so it was a mistake.DDR2 wouldn't fit in the motherboard i mentioned earlier since notch wouldn't fit.Here is what written on the sticker of the new RAM that isn't working: EasyPC Technology 1GB DDR PC-3200 CT1GD64SH08BL-5T in case you want to make some search.Thank you so much for your help. "JS" wrote: No the small difference in the values is insignificant and is actually in favor of the new ram as far as booting. Also sometimes a BIOS will not accurately read the memory sticks stated SPD numbers. Go over the operating voltage specs one more time and if no joy return the memory to the place you purchased it from and then use the Crucial Memory Advisor tool posted earlier. If you purchase the memory the "Advisor" recommends your problems should be solved. -- JS http://www.pagestart.com "Pool" wrote in message ... Hi JS Sorry i couldn't write you before today i was out of the city.I tried installing new RAM and i was able to boot and check BIOS like you told me before to compare between old and new RAM values in BIOS. New RAM Under Advanced chipset features Configure DRAM Timing [SPD] CAS Latency Time 3 Active To Percharge Delay 8 DRAM RAS# to CAS# Delay 4 DRAM RAS# Percharge 4 Refresh Mode Select 7.8us Old RAM Configure DRAM Timing [SPD] CAS Latency Time 3 Active To Perchange Delay 8 DRAM RAS# to CAS# Delay 3 DRAM RAS# Percharge 3 Refresh Mode Select 7.8us Does that mean they aren't compatible and new RAM won't work with the motherboard i have.Please help.Thanks again. "JS" wrote: If the Power Supply fan is making uncommon noises then yes replace it with a unit that at least equal to the wattage rating on the power supply sticker. Look for the number of 12V rails and the wattage for each rail. If you have a 350 Watt power supply now then replace it with a 450 or 550 watt supply to give you some spare wattage in case you plan additional upgrades. Now as to the memory issue, if the computer works fine with the old memory sticks then you either have defective sticks or more likely incompatible memory. Try the Crucial Memory Advisor link: http://www.crucial.com/store/listmfgr.asp?cat=RAM From what you posted the value of your "Current CPU Temperature 64C" is way too high especially if the computer is basically at idle (no load). You may want to look at a better heatsink and fan plus Arctic Clean 1& 2 to clean off the old past or pad one your CPU http://www.arcticsilver.com/arcticlean.htm and Arctic "Ceramique" for the thermal paste. http://www.arcticsilver.com/ceramique.htm Read the instructions carefully on how to remove the old past/pad from the CPU and the clean it using Artic Clean. Same for applying the paste for a socket 478 CPU. Do it properly and you CPU should drop down to about 34C at idle. But take care of the memory issue first. Also check your existing values: CAS Latency Time 3 Active to Percharge Delay 8 DRAM RAS# to CAS# Delay 3 DRAM RAS# Percharge 3 How do these values compare with your old and new memory? -- JS http://www.pagestart.com "Pool" wrote in message ... Hi JS I cannot get the computer to boot using 1GB RAM so i have no way to enter BIOS.I can give you the information you wanted to know in BIOS using 256MB RAM which is installed to be able to use the computer PC Health Status VCore OK DDR25V OK +3.3V OK +5V Ok +12V OK Current CPU Temperature 64C Current CPU FAN Speed 3835 RPM Current System FAN Speed 0 RPM Frequency / Voltage Control CPU Host Clock Control [Disabled] CPU Host Frequency(MHZ) 100 AGP/PCI/SRC Fixed 66/33/100 Memory Frequency For [Auto] Memory Frequency(MHZ) 400 AGP/PCI/SRC Frequency(MHZ) 66/33/100 DIMM over Voltage Control [Normal] AGP over Voltage Control [Normal] CPU Voltage Control [Normal] Normal CPU VCore 1.5256V Advanced Chipest Features Configure DRAM Timing [SPD] CAS Latency Time 3 Active to Percharge Delay 8 DRAM RAS# to CAS# Delay 3 DRAM RAS# Percharge 3 Refresh Mode Select 7.8 us When i pressed on CTRL+F1 it didn't give me anything Please tell me what i shall i do next. If i consider getting a new RAM what are the specifications i should look for inorder to be sure it will work with the motherboard i have.Also do you think changing power supply unit could solve the problem because lately it's Fan make noises not like it used to be.Thanks again It's sound more and more like M.I.T settings in your BIOS. What you need to do is only insert one memory stick, boot and see if you can immediately enter the BIOS. Do this by "Powering ON the computer and pressing Del key several time to immediately will allow you to enter BIOS setup. If you can select "Load Optimized Defaults", then Save and Exit the BIOS. Then power down, turn off the power supply or remove the power cord wait 30 seconds and insert the second memory stick.Power up and if see if all is well. If still having problems power down and remove one stick. Then power up and from the main BIOS Menu enter the "Check PC Health" status. (Page 53 of the motherboard manual) Next check the "Frequency and Voltage Control" The "CPU Core voltage" , "Memory Frequency (MHz)" and "CPU Host Frequency (MHz)" Note: Mem Freq number must be equal to or less the Ram Stick ratings. (Page 55) Same for memory voltages. If you can change the After you check and adjust any values if necessary go back to the main BIOS menu and press Ctrl+F1, Gigabyte sometime hides the advanced setting from users. Let me know if Ctrl+F1 brings up any additional bios settings -- JS http://www.pagestart.com "Pool" wrote in message ... Hi JS Here are the specifications of both new and old RAM Elixir 256MB DDR-400MHZ , PC3200U-30330 N2DS25680BT-ST 0351.EME03C1201B.120393M.XX.TW Kingston: 1GB DDR PC-3200 ELPIDA , D5108AGTA-5B-E CT1GD64SH08BL-5T I tried installing one stick of 1GB then i booted it worked normally.Then when i tried booting again it took around 20 seconds to boot up.I tried booting a third time it didn't boot at all.Now i am using old RAM.Is it a RAM problem or is it something with the power supply.Please help. "JS" wrote: There is a Elixir Part number, see the web site link below and use there part numbering scheme, when you post back the actual part number then I can do a better comparison. http://www.elixir-memory.com/sup_name_rul_2.asp Also you Gigabyte motherboard uses "MIT's" technology which has been know to cause the PC to fail to boot on socket 775 motherboards when you first install new memory, this may or may not be the case with the older sockets 478 motherboards. The solution is to only install one memory stick and power up the PC and let the BIOS "learn" the memory requirements and then after a few successful reboots then install the second memory stick. -- JS http://www.pagestart.com "Pool" wrote in message ... Hi Everyone Thank you so much for trying to help me solve the problem i am having. I checked Memory frequency in Bios and here what i found Memory Frequency For [Auto] Memory Frequency(MHZ) 400 AGP/PCI/SRC Frequency(MHZ) 66/33/100 Also here is what written on the old RAM which came with the computer,Please tell me if it is the same compatible with the new RAM i bought recently.Now i installed old RAM inorder to be able to use the computer. Old RAM : Two sticks of Elixir 256MB DDR-400MHZ, CL3 PC3200U-30330 |
