Aopen xCube SiS661FX 2x1Gb ram problem

magnastik

Hi!

I've a xCube from Aopen, the model is EZ661 with a AOpen s661FXm(-S) / s661FXm-7(S) / s661FXm-FSN motherboard.
In the specs sheet it says it can support 2gb DDR400, so i bought a 2x1GB ddr400 from eBay to place instead of my 2x512mb.

But now i've a problem.. when i tried to install the 2 dimms and boot i hear a a long beep, and then again... and ....

I tried just 1gb dimm but the result is the same.

I flashed the bios to (i believe) latest aopen version (from aopen ftp).
The problem remained.

In bios changed the RAM speed from 400mhz to 333Mhz and it booted but only recognize 512mb and then when starting to load Windows Vista it boots again, and if i try to go in Safe mode i get a blue screen, and it says "Dumping Physical Memory" or something like that.

So, i would like some help to go through this.

Here is the specs of my xcube: ftp://ftp.aopen.ru/pub/xccube/ez65ii/eig/ez65iiez61-eg-e.pdf (the bottom right one, UX661)

The online eSupport Scan gave me this results:

It seem you really bought 2x1GiB RAM but you bought el-cheapo modules built from High Density RAM and your motherboard (and many, many others) does not like them.

Return them and buy quality RAM.
