Ok I keep hearing about how important memory timing can be on the ASUS A8N-SLI Premium . How do I tell what the timing is on my memory so I can check to see if the BIOS is setting it up properly. My ASUS A8N-SLI Premium locks up when doing a memory test in soft sandra. I am also using non-approved RAM, Patriot Signature 2GB (2 x 1GB) 184-Pin DDR SDRAM Unbuffered DDR 400 (PC 3200). I never had a motherboard so picky with RAM.

It looks like it is setting the timing correctly. I guess there is not way out of this. These boards are junk. I put this system together for work. I guess I should have stayed safe with a single processor pentium 4 system. Now the question what is the lesser of evils here. I am thinking a new motherboard and try to save the CPU and other stuff. From what I have read you can go on forever trying to find the right combination of memory to get this thing to work then it is a crap shoot.

Try enabling 2T timing in BIOS, if it's at 1T that could be the problem. What timings are you running? Sometimes loosening it a bit (eg. 3-4-4-8) helps, or just running it at 333 (not the happiest solution).

It could very well be the memory controller on the CPU that's being picky, not the mobo.

Perry, you NEED to get Memtest86+ and run that on your system. It's a small .iso image that you burn to a CD. You then boot up to that CD and it tests your memory exhaustively and will tell you which tests and memory ranges fail. It could be your RAM.

Ok I will download the memtest86+ and try that. I took some ram out of my desktop machine here at work and it did exactly the same thing with it. I will let you know what happens.

Thanks

That's odd. Did you try upping your Vdimm yet? I haven't tried as low as 2.6V, 2.75V works at DDR400 with stock timings on my mobo (same one).

I don't see any obvious errors using memtest86+. I upped the voltage to 2.7V and it still locks on the windows based soft sandra memory tests.

Ok latest, everything passed the memtest86+ test. I upped the voltage on the RAM again to 2.75V and it seems to be stable with the soft sandra memory tests in burn in mode. My 12V rail is 11.67V. I am not sure if that is good or bad. The other voltages seem pretty close to spec. I have a thermaltake 430W power supply I hope that is enough.

I was ignorant of the RAM issue and money was not object since it was uncle sam's money. Maybe my problems are solved for the moment. I hope you are right about the board. I am going to use it to monitor and control long term tests.

Ok I finally got the board stable using 2.9V on the RAM. They are running kinda hot but holding in there on the Soft Sandra burn in test running continous.

Thanks for all the help.

PS I am ordering corsair memory for it.
