Won't boot into windows with 2nd memory slot filled

[Mexman]

When I populate slot2 with 512mb noname ddr1 I cannot boot into windows, BIOS comes up ok and memory tests ok. This is intermittent but now almost 90% of the time it won't boot. slot1 contains a 1GB kingston pc3200.

With no ddr in slot2 it boots ok and with a 1GB stick (corsair) it boots ok. I guess it was the noname 512MB stick but seems strange it passed all the memory tests (from ubuntu grub loader)

MB is an Asus K8S-MX

hi what happens when you put the 512MB stick in slot 1 and the 1gb stick in slot 2? kinda surprised your running win7 64bit on just 1.5 gb of ram.

It's win7 32bit and runs just fine with a decent graphics card and minimal multi-tasking.

I'll try switching them, but suspect it's the no name ram since it now works with a name brand.

Can you post the model of that Computer?
There are some MOBO that comes with 4 slots for RAM, 2 can support ddr and the other supports other type of RAM.
or the 512 RAM of yours is faulty.

It's a homemade PC with an Asus K8S-MX which is 2 slots ddr400.

I tested the 'faulty' 512mb stick for hours w/o any errors - this is what is confusing.

and it did work consistently for 2 years, then the last 2 weeks started not to boot.

Mexman,

I would suggest you let go of that RAM, everything has an ENDING, everything gets OLD. 2 years of service. not bad.
Try installing new RAM, lets see if the problem still occurs.

By the way, your MOBO can only support 2GB of RAM. as what on the specs i have read.

Thanks, as I said in the OP, I installed a corsair 1gb stick in the 2nd slot and it has been working ever since.
