surfer96 Posted January 27, 2006 Share Posted January 27, 2006 Just got myself a new Asus K8V-MX motherboard. I was hoping to be able to use a couple of Corsair PC2100 ECC sticks that I still had lying around. According Asus the MB should work with PC2100 ECC memory. When starting the pc I get no video signal. I tried using both sticks, one stick, different slots, but nogo. With no memory I get the usual beeps at startup, but with the memory there are no beeps; everything appears okay except I don't have video. Then I took out a DDR400 stick out of my other pc and using this stick my newly build pc works without any problem. This stick is not Corsair btw. Did anyone solve similar problems or do I just throw away the old Corsairs and get myself new DDR400 memory? Any thoughts are much appreciated. TIA!

Yellowbeard Posted January 27, 2006 Share Posted January 27, 2006 Sorry to be the bearer of bad news but, according to ASUS, that MOBO does not support ECC memory: http://usa.asus.com/products4.aspx?modelmenu=2&model=754&l1=3&l2=14&l3=0 You may want to look at the Corsair memory suggester to pick some appropriate memory for your system: http://www.corsairmemory.com/corsair/configurator_search.html Mike.

surfer96 Posted January 27, 2006 Author Share Posted January 27, 2006 Mmm, actually the url you posted reads: "2 x DIMM, max. 2GB, DDR400/ 333/ 266, ECC, non-ECC, un-buffered memory" So I guess it should support both, just what the manual says as well.

Yellowbeard Posted January 27, 2006 Share Posted January 27, 2006 Wierd, I did misread that, sorry. However, IIRC, that chipset does not support ECC memory. Mebbe RAM GUY can help out. Bad thing is, empirically, you have proven that you have "a" problem. My money is that this MOBO will not run ECC memory. Good luck tho. Mike.

Yellowbeard Posted January 27, 2006 Share Posted January 27, 2006 Can you post the complete part # and info from the sticker on the memory? I think I have it figured out. The MOBO will support ECC but not registered memory. If you memory is registered, and not unbuffered, that is your problem. The P4C800 series MOBOs from ASUS were the same way and people kept trying to run ECC registered memory in them. They will support ECC but it has to be unbuffered ECC, not registered ECC. Hope this helps. Mike. Link to comment Share on other sites More sharing options...

surfer96 Posted January 28, 2006 Author Share Posted January 28, 2006 The labels on the two sticks read: CM72SD256R-2100/M 014225 PC2100R-25330-A1 CM72SD256R-2100/Y 020228 PC2100R-25330-A1 Link to comment Share on other sites More sharing options...
Yellowbeard Posted January 28, 2006 Share Posted January 28, 2006 The "R" in 2100R means Registered and your MOBO does not support registered memory. It will run unbuffered ECC memory but not Registered ECC memory. That's what I actually meant in my first reply, I was not clear though. Mike.

Yellowbeard Posted January 28, 2006 Share Posted January 28, 2006 Sorry to be the bearer of bad news. But, atleast memory is getting cheap these days. You can get a full gig of Value Select for less than $100 last I looked. Mike. Link to comment Share on other sites More sharing options...
