New RAM Memory voltage problem i think

Gigabyte Ga-ma785gm-us2h motherboard
January 31, 2010 at 23:25:40
Specs: Windows 7, AMD Athlon Dual Core 2.6GHz/ 4GB DDR2 Ram
I have a problem with my pc freezes or rebooting within 1 minute of loading windows when i installed my new memory.

I originally bought some OCZ PC2 8500 1066 DDR2 memory, but later i found out the voltage was too high. 2.2v that memory has, Motherboard manual says support 1.8v.

So went and bought some Kingston PC6400 800 DDR2 memory at 1.8v. But i get the same problem. I see this memory and my motherboard in computer builds advertised on the internet.

Why do i have a problem?

Did you clear CMOS after installing the new memory sticks ?

The BIOS may have settings that pertain to the previous memory, such as CAS Latency, RAS to CAS Delay, etc. You have to clear them for the new RAM sticks to work.

I assume you have seated RAM sticks properly.

After installing new RAM sticks, can you go into BIOS ?

Please also tell us how many RAM sticks you have, e.g. 4x1GB or 2x2GB or 1x4GB. Check your M/B manual if the M/B can handle the amount of memory you installed per slot.

You mat also have to adjust RAM voltage manually in BIOS.

Hope the above helps.

Make sure the ram settings in bios are set according to ram manufacture specs. Are u sure the ram is compatible with your board? And try to run memtest to test the memory.

I check qvl for your gigabyte board and close match i can find is "kingston kvr800d2n5/512 or 1g" but they said "due to massive memory models on the market, we can only verify some oe them" did u test the memory using memtest?
