Ram Issues with Gigabyte EP45-UD3P

post #1 of 3
Thread Starter 
Hello all,

I recently gave my brother my sig rig as it's too loud for my dorm room. Today, he bought 2GB, in the form of two dimms, of Kingston Hyper X DDR2 PC6400 to boost the performance. I thought the install would be fairly simple, but it has given me a lot of problems. After installing the two dimms alongside my one 2GB dimm of OCZ "fatal1ty" ram, the system would hang at the boot screen before rebooting itself. The next logical thing to do was to take out the OCZ ram and run just the Hyper X. Surprisingly, nothing changed; still a hang at the boot screen. So I tried just one dimm of the Hyper X and it booted like normal. I tried the second dimm by itself and the system hung at the boot logo. Is it safe to assume that the one stick of ram that caused the system to not boot is faulty?

Here's my second issue. After using just good dimm of Hyper X, with my single OCZ dimm, the system still hangs at the boot logo! I've tried using different slots, setting the voltage manually to both 2.0V and 2.1V, but nothing seems to fix the issue. It will boot with either the OCZ dimm or the Hyper X dimm, but not both at the same time.

Does anybody know what the issue could be? It's really driving me nuts.

Happy Holidays,

If you have diffrent ram it could be the BIOS cant detect the correct speed, if the BIOS chooses too high clocks it may cause lockups or Ram corruption you should go to BIOS and manually set the clock of the slowest Ram in the System.

Both the OCZ dimm and the Hyper X dimm are clocked at 800mhz though.
