Motherboard won't accept more than 4gb RAM!

[Franc_CAT]

So i'm upgrading my PC which has an IPMEL-Q5 from American Megatrends Mobo (Everywhere shows that can use up to 16gb of RAM).

I bought 4x2Gb of 800mhz ddr2 RAM. 2x2gb works fine, but when i try to stick more than that, it starts beeping.

Yes i have tried the mobo battery thing, yes i have a 64bit SO (win8.1 pro), yes i've tried all RAMS one by one and all work fine.

I have not been able to find a MOBO BIOS update, it's impossible to find one. That pice of crap program of BIOS agent or whatever tells me the "AMI" is not updated, but you have to pay for the damn program...

Anybody knows what happens?
Thanks.

You are probably not using the right slots.

Read page two of this: ftp://ftp.maxdata.com/MAXDATA_PCs/Desktop/01_Mainboards/2%20Pegatron/IPMEL-Q5/Manual/IPMEL-Q5%20menual%20.pdf


Make sure all RAM is removed from the system.
Then install your two new sticks in the slots labelled 'Channel A' . Check if it works.

If not, move the two sticks to the 'Channel B' slots and try again.


If it still doesn't work your memory may not be compatible in dual channel.

Yeah, i saw page two days ago. Just tells me i can in fact use more than 4gb.

As I said, al RAM is NEW and same. Im working fine with 2 of the 4 sticks (which are place in channel A both of them).

So, ram work fine and are dual channel compatible. What else could be?

Ah it may be that your board doesn't support quad channel. The memory controller may not be able to handle 4 800Mhz sticks.

Your best bet might be to use 2 sticks or get an 8gb kit made of 2x 4gb sticks- Those are expensive though!

Has this any sense? I mean? Does this "no quadra channel" exist?

The motherboard has 2 channels with 4 slots; therefore it supports dual channel mode. Quad channel mode doesn't exist for older motherboards.

Franc_CAT what memory kit are you trying to install?

4x2gb ddr2 800mhz

That's all it says on the modules? No manufacturer, no part number, etc.

Kingston PC2-6400 ddr2 800mhz 2gb

Kingston always have a part number for their kits.

I've tried with QMOX and Kingston and all does the same, it's not about the ram it's about the mobo/Bios

 

[GhislainG]

It's an old system for which a new BIOS doesn't seem to exist. Are the modules that you tried certified to work with other Q45 motherboards?
