ASUS 8N-SLI Deluxe Memory Upgrade Advice

Recommended Posts

Hi Ram Guru,

 

I have the following system

 

Asus A8N-SLI Deluxe Bios Ver015

AMD Athlon 64 4000+

Corsair 1GB TWINX-3200XL DDR

 

I would like to upgrade the ram to either 2gb or 3gb.

 

I can purchase a TWINX2048-3200C2 or TWINX1048-3200C2 or TWINX2048-3500LL here in Australia.

 

What would work with my existing ram, motherboard and CPU, @400MHz and give me the most available ram for my motherboard?

 

Lastly how would u recommend i config my bios for your recommended upgrade with my exsting ram present as well.

 

Cheers,

As I said so many times, the IC chips used in the 3200XL's are no longer being produced. In addition, no 1GB stick at all whatsoever should be mixed with your existing 3200XL's since the IC densities on the 1GB sticks (2GB kits) are completely different from those on the 3200XL's. Moreover, the Athlon 64 memory controller is especially allergic to mixed IC's and mixed SPD chips. If you choose to ignore all that and mix the modules anyway, either your system will refuse to even POST at all, or your memory speed will drop to a molasses-slow 100MHz (DDR200/PC1600) speed and may not run stably at even 133MHz (DDR266/PC2100) speed. And even if all of your modules exactly match each other, your memory speed will still default to 166MHz (DDR333/PC2700) speed, forcing you to manually reset the memory speed to 200MHz (DDR400/PC3200) speed in the BIOS.

 

In your case, try to find another use for your existing 3200XL's, and just go with one TWINX2048-3200C2 or TWINX2048-3500LL kit for best performance.

Thanks for the quick reply.

 

If i take out my existing ram and get 2 * TWINX2048-3500LL will that work ok?

 

It will. However, if you're not overclocking your CPU, you should make sure that the memory speed is at DDR400 speed by checking the BIOS settings. Otherwise, if you intend to run that memory at its rated DDR433 speed, you should also overclock your CPU by raising the base CPU value from 200MHz to 217MHz.
