arrowana Posted January 24, 2006 Share Posted January 24, 2006 Hi, I am just replaced my Abit AV8 MB with a DFI LanParty NF4-Utra-D. I had tried a lot of diff. config., including the default setting (3-3-3-8, @2.7-2.8V), I also try diff. bios version 6-23 and 11-14, and the only divider working is 3/4. Even at this divider it seem like I can't go over 207 Mhz. Is there any reason why it can't work with other divider, and how come I can't go over 207 Mhz?

Corsair Employees RAM GUY Posted January 24, 2006 Corsair Employees Share Posted January 24, 2006 Can you tell me the bios settings you have set for both CPU and memory and any performance settings that you may have set? Link to comment Share on other sites More sharing options...
arrowana Posted January 25, 2006 Author Share Posted January 25, 2006 277 FSB Freq. is the max stable Freq. anything higher than this will fail memtest or prime95. This Opteron 165 was able to hit 2.7G with the Abit MB. Please let me know if I can get any higher clock than this. I was expected at least 220-230 Mhz memory clock from this XMS line. Thank you.

Corsair Employees RAM GUY Posted January 25, 2006 Corsair Employees Share Posted January 25, 2006 I would try and set the CPU and memory at 1-1 and see how high you can get, but you are ruuning the memory over spec so there is not a lot I can do. Also I would set the memory voltage at 2.8 Volts as well. Link to comment Share on other sites More sharing options...
arrowana Posted January 25, 2006 Author Share Posted January 25, 2006 I did try 1:1 and the highest stable I could get is 208. I know that the memory is rated for 200Mhz, but the question here is why I can't run it in any other divider (only work with 3/4-150Mhz divider). The reason I chose this XMS line is for overclock, that why I pay extra money to get this memory. Otherwise I would just buy a value ram at 2/3 the cost. I heard someone on DFI board say that, the new Rev. of the TwinX is working fine with DFI board. I just want to know if this true, and if it is possible for me to RMA this set and get a newer Rev. or pay extra to get the higher rated clock. Thanks.

Corsair Employees RAM GUY Posted January 25, 2006 Corsair Employees Share Posted January 25, 2006 If you want to run higer than DDR400 I would suggest you use our XMS4000 modules that would allow a higher over clock. But the divider is a bios/CPU issue and more than likely as the bios matures the Over clock may Improve. And there has never been any issue with our modules on any DFI MB, just a few on DFI's forum seem to be trying to extort memory from us. Link to comment Share on other sites More sharing options...
ahshing Posted February 7, 2006 Share Posted February 7, 2006 hi man,i also got the same problem as u! my memory is XMS3202V2.2 with nanya chip i found the memory that cannot reach higher that 2.8v,and i'm running at DDR500 3-4-4-10 1T with a little bit unstabilty.so i also wonder why i didnt buy the value ram with samsung UCCC chip,near 2/3 price but OC to DDR500 3-3-3-8...very confusing:(: :(: Link to comment Share on other sites More sharing options...

If you are getting DDR500 out of our DDR400 modules that's a great O.C. and our Value Select DDR400 modules running at DDR500 would be verry un-likely.
