Motherboard Asus A8S-X Chipset SiS 756 AMD Hammer
CPU AMD Athlon 64 3500+ Venice S939 Step DH-E6
RAM 1024 MB (PC3200 DDR SDRAM) Corsair VS1GB400C3
Ram timings are "currently defaulted" at 3-3-3-8
1. Can this RAM by tweaked/Overclocked?
2. If yes, How do I OC/TWEAK this RAM?
3. Is their some Software or a good Website to explain this?
4. Do I OC/TWEAK RAM via Software or BIOS settings?
5. If Yes, what are some of the things I should look for?
6. What are some of the benefits to overclocking RAM?
7. How can I test to measure any benefits to OC'ing the RAM?
8. Is their an issue with stability and how can I avoid it?
If you are unable to answer or think the reply would just be way too
long of a post, could you PLEASE provide me with a list of some good
websites on this subjects? Especially some websites with detailed
steps on overclocking my RAM?
P.S. If this is the wrong NG let me know. And if my post was not
complete enough to understand what I am asking then please ask me what
I left out of the post.
Thank You very much

You CPU can't be both a Hammer and Venice core. E6 stepping is the Venice
Yes, but it's of little value to do so normally.
Raise the ram clock. Increase volage to ram.
Probably somewhere. I haven't looked for it.
Normally the bios.
There are no real benefits to overclocking ram. Lowering CAS latency will
do more, but not enough to make a big difference in system performance.
Assuming you want to get better performance out of your system, you should
lower the default ram clock by 33 or 66MHz. Lower the HT speed from 5x to
4x or even 3x. And then crank the FSB speed from the default 200MHz to,
well, as high as it will work or that you want. I don't knoe much about
the SIS 756, but I've overclocked the older 755 easily on several boards.
I'd assume the 756 would be better. Your cpu has an 11 multiplier and
defaults to 2200MHz. Set ram to 166MHz (might already be there if using
BySpd), Set HT to 4x, set cpu freq. to 234Mhz and reboot. Both my Venice
core cpu's with a default of 2200MHz will work at 234Mhz without raising
cpu voltage. YMMV. Always use a boot floppy or cd to to test overclocking.
A memtest boot media works well.
