First, my system specs:
AMD Athlon64 3000 NewCastle Skt754 (CG Stepping, 2GHz base freq)
2x512MB Crucial/Micron Single Sided (rated 3-3-3-8 timings) link
Asus K8N-E Deluxe rev 1.03 bios 1006 (mem voltage limited to 2.7V)
PNY GeForce4 Ti4200 64MB 8x
SATA hard drives
Second, some background:
As a prelude to possibly doing some slight overclocking, I decided to see what memory timings my memory could handle at stock speed. Originally, I would have liked to see some 2-2-2 timings (even though it is value ram), but in the end I could only get 2.5-2-2. However, as the title says, I found that I could get the 2-2-2 timings if I ran my processor with a 4x multiplier, instead of the 10x default. Everything else was running at full speed.
800MHz HT Bus (200*4)
DDR400 speed (w/ 2-2-2 timings)
but CPU at 800MHZ (4x mult)
if I tried upping the multiplier to 10x, I would get a System Failed due to CPU Overclocking on POST.
currently, I'm running stable with
800MHz HT Bus (200*4)
DDR400 speed (w/ 2.5-2-2 timings)
CPU at 2000MHZ (10x mult)
so, why does the CPU speed make the difference?
EDIT:
Vcore is stock
Vdimm is 2.6V (i don't remember what the rated voltage is... either 2.5 or 2.6).
in truth, i wasn't expecting the memory to run 2-2-2, i just found it weird that it would be dependent on the CPU frequency
power supply is a 450W Antec SurePower
I've got 4 Hard drives in the system now, and 2 optical drives. I don't think i'm that close to overloading the power supply.
And i didn't try 2-2-2 at a 2T command rate. I figured that 2.5-2-2 at 1T is better than 2-2-2 at 2T
