Opteron 165 and HyperX, problem

[cruZZade]

Hi, I recently bought new memory to my computer, unfortunately I chose Kingston HyperX KHX3200AK2/2G 2GB. Before the Kingston I used Corsair TWINX 1024 2x512mb 3200XL which worked great.

 

The opteron is overclocked to 2,8Ghz @ stock voltage and is stable.

 

The problem is, with everything at stock speed, I have no problem running the memory at advertised speeds (2,3,2,6), but as soon as I raise the FSB just a little my computer won't boot. Only if i drastically lowers the divider for the memory I can boot overclocked. To be able to even run 2,8Ghz I have to set the divider for 100mhz, making my memory run in ~156 mhz each.

 

Why is that? It worked flawlessly with the Corsairmemory. I understand if i weren't able to overclock this memory much but since I can't even make it running att stockspeed (using divider) is troubling me.

Hello,

 

Kingston modules for some reason do not work well on the DFI board.

 

@200Mhz try these settings.

Which Bios should I use and in which slots? I'm currently using 6-23-3 and I'm running them in orange slots.

 

Thanks for the help, I'll try those settings!

 

EDIT: Tried your settings, no luck. As said, I can get the modules working in 200mhz with the specified latency, BUT as soon as I overclock the cpu just a tiny bit I can't boot, even if I use a divider for the memories (not exceeding memory speed of 200mhz). And I know this cpu overclocks without problem since I could do 312mhz fsb (2,8ghz) without problems using my old memory on stock cpu voltage.

Damnation! I just bought the same memory at Fry's on sale for $170 (2x1GB). I may use it before I get around to trying overclocking and then ebay it.

 

Is there any memory currently in production that will o/c well on the Ultra-D, 2x1GB?

What kind of o/c are you looking for?

Sounds like the old hot rod saying, "How fast can I go? Answer: How much do you want to pay?" I guess a "reasonable" balance between speed and value is the best I can say. I've heard said that the current DDR1 sticks are weak EOL products and no longer o/c well. Kits of OCZ Platinum EL Rev2 are going for very high $ on ebay. If there are good kits still in retail channels, I can keep my eye out for them. What do you say?
