Four-year-old budget rig, recently started upgrading in bits.

Pentium E5400 Wolfdale CPU
Gigabyte G41MT-D3 mobo

Previously I had installed 2 x 2GB sticks of Kingston DDR3 1333mhz RAM.

This mobo only supports RAM speed up to 1066mhz and has been happily downclocking for four years.

Recently bought 2 x 4GB Kingston DDR3 1333mhz .
http://www.kingston.com/en/memory/search/?partid=kvr13n9s8k2/8

Now when I try to boot with the new RAM, I get a continuous beeping which, according to Gigabyte, is a "power error".
No problem at all with the old RAM; I put it back in, pc boots infallibly.

ETA: After trawling the internet for some days, I stumbled upon this: http://www.overclock.net/t/113885/info-what-is-the-difference-between-low-density-and-high-density-ram

This is an old post from 2006, but is the only mention I have found of density. My new RAM does appear to be so-called 'high density.' Still a relevant concern in RAM, the density?

(Mobo only has two RAM slots; runs dual-channel; is supposed to be able to support up to 4GB in each slot.)

Any thoughts at all or avenues for testing will br gratefuuly accepted.

Hello, I'm Jewel with Kingston Technical Support. We apologize for the issue experienced with our ValueRAM. KVR13N9S8K2/8 is a high density or 1R using 4Gbit DRAM which is not supported by your GA-G41MT-D3 motherboard. We no longer support this motherboard as we do not manufacture memory that is compatible with it. You are welcome to return the memory to your place of purchase as it is incompatbile. If you are unable to, please contact us and we can work with you. Please call us at 1-800-435-0640 (USA and Canada only) M - F 6am - 6pm PT and I or another available Technician will assist you.

Thank you for selecting Kingston as your upgrade partner.

Have you tried to downclocking the RAM modules, you might not have to go all the way down to 1066MHz but this could stabalise your mobo. upgrading the mobo would be the quickest fix, let us know what you decide to do :)

I know that there are more variations in brands of components and more possible combinations than is physically quantifiable, but I could find no mention of this possible problem anywhere. I waz not aware that this was a problem. (Mind you, outdated and already an obscure board, what did I expect?)

Honestly, for the amount that new RAM will cost, I might as well keep these sticks go for a new board.

 


DRAM compatibility issues may arise when using very new memory modules on older motherboards. The KVR13N9S8K2/8 DRAM modules use eight 4 gigabit ICs per rank for a total of 4GiB per rank and one rank per module (1R mentioned by kingstonhq above). This is the same configuration as state of the art dual-rank 8GiB enthusiast modules. Many older motherboards simply don't support module densities this high, your G41MT-D3 is based on the Intel P41 chipset which is among the first to support DDR3 and support for the high density configuration is likely absent.
