Hey guys, I have some questions regarding memory timings. First of all, I am running the ASUS A8V Deluxe (K8T800Pro) with 1024mb of Corsair PC3200XLT (2 matched 512mb sticks) and noticed when I ran Sandra the other day that it was reporting my timings as 2-3-2-2@400Mhz DDR. I thought that these values seemed kind of low since the package the memory came in as well as Corsair’s web site reports the latency for these dims to be 2-2-2-5. I have everything in the bios as far as memory settings are concerned set to auto with the exception of the 2T command, I have it disabled. The systems runs extremely stable and I do not see any problems but am still curious if Sandra is correctly reporting the timings or if it really is running that low. Any thoughts?


Also, Sandra reports it as being in single channel mode for memory access. But from what I have read elsewhere this is not possible as the 3500+ is dual channel only right? So it is not possible to run the 3500+ in single channel memory mode from what I understand. Is that true? When I run the memory benchmark it is in the 5.9 gb/sec range which would indicate to me that it is in fact running in dual channel mode in order to achieve bandwidth like that right? So my questions come down to this…

Why does Sandra say my memory is single channel and not dual channel?
And what is with this memory timing of 2-3-2-2, is it real or is Sandra just misreporting the actual values?
Also, I am looking for other system information utilities like Sandra if anyone has any to recommend.

Okay guys, I got CPU-Z and confirmed what I thought before that sandra was misreporting the timing values and channel mode. Here is what CPU-Z reports...

Frequency - 200.3Mhz
FSB:DRAM - CPU/11.0
CAS#Latency - 2.0
RAS# to CAS# - 2
RAS# Precharge - 2
Cycle Time(TRAS) - 5
Bank Cycle Time(TRC) - 11
DRAM Idle Timer - 16

But this opens up more questions. What is the Bank Cycle Time(TRC) & DRAM Idle Timer values all about? And what is it that the T2 command does?

- May want to check out <A HREF="http://www.rojakpot.com" target="_new">BIOS Guide at RojakPot.com</A>.

Example: <A HREF="http://www.rojakpot.com/default.aspx?location=8&var1=0&var2=62" target="_new">DRAM Idle Timer</A>.

- DRAM Command Rate can be 1T or 2T. 1T would be faster. 2T is slower but can provide more stability in strenuous memory configurations - 4 two-rank (double-sided) dimms on a Athlon64, for example.

Thanks dude! That is exactly what I was looking for.
