XMS4000v1.1 Hynix chips + NF4 = ARRRRGHH!

RAMGuy,

I have a TwinX 1gb kit (2x512) I bought back in late 2003. SN 0341064. They worked great on my IC7, but since switching to a DFI NF4 Ultra-D it has been a nightmare. No way will they pass memtest86 at DDR 500. After much research it has become clear the NF4 chipset doesn't work well with Hynix RAM. Would it be possible to RMA this pair for a later version that works with the NF4? If so you will have a loyal customer forever.

Thanks,

Fred

Well I have no problem replacing your modules, however this MB seems to be picky in general and the replacement modules would be based on Samsung IC's which as I understand it have had the same basic issue. But I would suggest you make sure that you have the correct bios and the latest version and try testing the modules one at a time with http://www.memtest.org. In addition, some AMD CPU's might not over clock to the required frequency.

Thanks for the fast response RAMGuy. I tested them one at a time and dual. Fail memtest+ 1.60 at 250 Mhz either way. Also tried with 4 different bios revisions. No luck. Borrowed some TCCD based RAM and it passes all memtests at 250Mhz. Also overnight prime 95 stable at that speed, so the CPU is good. Is the new XMS4000 TCCD? Even if it's not TCCD I'd like to RMA.

Thanks,

Fred

RAMGuy,

Thanks for keeping up with the posts. I'm sure it's hard to do right after the move.

 

I have tried -1, -2 and -3 of the 704 BIOS and various versions of previous BIOS releases. None will work at rated speed. Probably have 15 hours in troubleshooting this with many many BIOS flashes and RAM swaps. Spent most of last weekend working on it. Also, there are multiple posts by other people of Hynix problems with the NF4. Check out this thread for one example:

Would it be ok if I filled out the RMA form?

Thanks again,

Fred

 

They have three version of bios as I remember and you will need to use the -1 bios but I would check with them.
