Hello.

I have the same trouble. Mb Asus M2N-E, AMD Athlon x2 3800+,2x Corsair XMS2 6400 512Mb, bios 0402.

By default, MB set timings to 5-5-5-18-2T, the system come unstable. But when I manually set them to 5-5-5-12-2T (as printed on pack), the system come stable. With 5-5-5-12-1T system doesn't work too.

Question: can this memory work with 1T coommand rate?

 

P.s. Please, excuse me for my English, it isn't my native language.

I just bought TWIN2X1024-5400C4 & configure it at my ASUS M2N-E 0502 + AMDX2 3800+. I manually set my RAM to 4-4-4-12-2T 1.9v. But when I test my system with CPU-Z under 1M condition, I got 44sec as the result. However, I read most of the forums & most of the people (who have the same pc combination as mine) got better result than me, probably from 21~32sec under 1M condition. Can anyone helps me to improve the result?

 

Besides, I always see people ask to test RAM by memorytest86, may I know the purposes of using it?

When I had an Opteron 148 overclocked to 290 X 10 = 2.9GHz and two gigs of DDR400 PC3200XL's I achieved a ~28s SuperPi so I do not know where these people are getting their marks from.

 

Here's a screenshot of a 3800+ X2 at stock FSB.

Note that this person has a 40s SuperPi. No one is getting a 3800+X2 to 21 - 32s without some overclocking. Even 32s is more to the 2.5Ghz A64. 21s is in the realm of Core2 and not AMD64 unless on Liquid Nitrogen and in the 3.6Ghz range.

 

Here is a 3800+ at ~3.0Ghz with a 28.2s SuperPi.

Memtest will force the RAM to work very hard.

 

Research:

Thanks for your respond!

1) So, your meaning is that my SuperPI reading is normal, am I right?

2) After running Memorytest, what can I understand about my RAM?

Yes, it is normal for your system. After running memory test and finding no errors you can be reassured that your DRAM is functioning within normal system parameters.
