DDR-3 speed issue

[Kjetil Valhovd_1]

I have a problem with mith my DDR-3 memory.
Its a DDR-3 PC3 10600R 1333, who runs at 1066.

Installed in a G6-server which is brand new.
Is there a way to change the FSB-Mem ratio on server BIOS ?

Please advise anyone :-)

Thanks!

I'm afraid NO for this model.

[Kjetil Valhovd_1]

Any other way I can correct this?
Or do I have to get the mem. replaced, it would be nice to get the speed thats intended :-)

What is the exact model of the server. I thought it is DL 380 G6. Am I right?

[Kjetil Valhovd_1]

It is a HP BL280c system.

Sorry, I posted the thread in the wrong section. Any moderator feel free to move the thread to Blade-section.

Hi,

The speed 1333 is supported setting in ROM based setup utility (RBSU).

Please refer page 20-21 in the below documnet:

Three things affect the bus speed.

1. Processor - Requires a 95 watt processor
2. Memory installed - Incorrect memory confguration will slow the bus down
3. BIOS setting allowing support for the 8Gb modules.

See the following quickspec for a rought idea about the memory possiblities

Hi.

With the new G6 platform and the DDR3 there are som new rules as mentioned above.

I'm not exactly sure but I think the clockspeed depends on how many DIMMS you have installed in a channel.

If you populate 1 channel with DIMMs you have 1333MHz
If you populate 2 channels with DIMMs you have 1066MHz
If you populate 3 channels with DIMMs you have 800MHz


check out HP's DDR3 config tool to get the right config.

Thanks a lot guys.
I will try the mentioned tips and see If I can get it to work properly.

I will let you know!

This is the mem config I am running:
2 x X5550 Proc. with (12x8GB)= 96GB RAM

So there is only 1 way to config the memory as far as I can see.

Any ideas?

Thanks again.
