Mixing Brands, Different Timings on X2-3800+ 939?

[mamisano]

Need some help with a problem I am having. Here is the scenario...

Replaced board, CPU and memory in my old workstation that was an X2-3800+ with 2x 1GB G.Skill PC3200 2-3-3-5.

Took the G.Skill PC3200 and installed into my server to bump up to 4GB.

Server:

• SuperMicro H8SSL-i Socket 939 board, ServerWorks HT1000 chipset

• Athlon X2-3800+ JH-E6 stepping

• 2x 1GB GEIL PC3200 ValueRam 3-4-4-8

I upgraded to latest BIOS, install the additional G.Skill memory and now the RAM is only running at 133mhz (DDR266).

Downgraded to older BIOS, same problem.

Upgraded to latest BIOS, manually set ram timings to slower of the 2 memory brands (3-4-4-8), same problem.

No way to "SET" the memory speed, only option is to set the Limit.

No option to set memory voltage in BIOS.




Emailed tech support and they stated that the different timings of the two brands was causing the problem and that I should purchase 4 sticks of their recommended memory.


Any ideas???

I could be wrong but, my guess is that your system is going to revert to the slower speed with any 4 x 1gb kit. If it was purely a timings issue, then disabling SPD and setting timings manually should have resolved the speed drop. That's just a guess but based on what I have seen other systems (esp AMD based) I don't think buying new memory will resolve it. They gave you the easy answer IMO.
