Service & Support FAQ:

Q: I can't find my question answered in this FAQ section. What should I do?
A: Email Technical Support or Post on Forum.

Q: What type of warranty do I get for purchasing GeIL memory?
A: GeIL offers Lifetime Warranty on all Memory Modules.

Q: I installed GeIL DDR memory module and my Windows won't start every time I boot, and crashes almost immediately even if it does start. What did I do wrong?
A: On some motherboards, the memory voltage sensor is not accurately calibrated and the "DIMM Voltage" is being mis-represented in BIOS screen. Set/adjust the memory core voltage to 2.7 or 2.8 volts. All GeIL memory modules have passed the torture test at 3v to survive in this PC market filled with all sorts of different grade power supply units and motherboard voltage sensors.

Q: I set the voltage like you mentioned in the last QA, but my system still doesn't boot. It kept beeping through the PC speaker. What am I doing wrong?
A: Remove the memory module and make sure the module is seated down correctly and secured.

Q: How do I install memory correctly?
A: Remove the memory from the package. DDR module has 1 notch a little off the center. Now look inside the memory slot and note the corresponding groves. Align the DIMM, then push it in until the lock tabs (on the left and right side of the socket) comes up automatically. If the tabs have to be manually put into place, the memory may not be installed properly.

Q: I installed new memory and the system will not reboot even with the original memory installed by itself.
A: This is due to improper installation. Reinstall memory making sure the module(s) are fully seated and that they are locked in place.

Q: Windows recognizes both modules separately but not together.
A: In windows select the start menu, select run, type MSCONFIG, hit ok, select the advanced tab at the lower right corner. Now find the option that states "Limit memory to" and uncheck it. Reboot and the system will reflect the proper amount of memory.

Q: The 400MHz DDR DIMM apparently seems to work. However, it only works at speeds lower than 400MHz. What's going on?
A: In order to set your DDR to 400MHz (200MHz x2), the CPU's fsb needs to be overclocked. With the CPU to DIMM ratio of 1:1, the CPU's fsb will have to be 200MHz, making the resulting CPU speed too high for the CPU to boot properly. It is not the DDR module that failed to boot, bur rather the CPU itself. The only way to successfully boot your system with DDR400 setting is to choose a lower CPU to DIMM ratio of 3:4 or 4:5, which will make CPU fsb to be 150MHz or 160MHz respectively. Some motherboards show these 2 settings as DDR266 or DDR333. It's actually the ratio that gets modified. Please note that at the time of this QA, only the top model CPU heat sink/cooling fan can properly cool down the the CPU.

Q: I get instability when running my PC. What can I do?
A: Try booting up each module separately and see if your PC is stable. If one of them has instability problems while the other don't, then the one with instability problems is to blame. Try placing the memory modules in different slots. Some motherboards have had problems with certain slots occupied. Set the memory timings in the BIOS to the rated memory timings. Upgrade your BIOS to the latest version, instability issues sometimes can be solved by updating to the latest version. Make sure "Spread Spectrum Modulation" or "SDRAM Frequency Modulation" is disabled in the bios. Try enabling the "AutoDectect DIMM/ PCI CLK" option in the BIOS.

Q: Can I under-clock GeIL memory?
A: Yes, GeIL Memory is backwards compatible and can be under-clocked.

Q: What if my motherboard is not on your compatibility list?
A: Many mainboards are compatible with GeIL memory even though it is not listed on our compatibility list.
