I recently built a system:
Abit NF7-S V2, 2X512mb twinx duel channel 3200 corsair ram, amd xp 2500+
chip (barton), ati radeon 9700 pro, sb audigy2 zs platinum are the main
components (as well as a standard IDE western digital 40 gig hard drive).
Shouldn't I be able to get the memory to run at 400 duel channel? It only
goes up to 333, and I get problems if I try 400 (system instabilities).
Also, I can't use the bios to set the frequency to 3200 (has preset as 2500
or 3200) without causing instabilities.
So far I've tried and had work:
I've upped the external clock from 166 to 172 (with multiplier at
11), set the CPU FSB / DRAM ration from auto to 6 / 6, and changed the CPU
core voltage from 1.6 to 1.7. Is this good for a test change? Everything
is running stable at the moment, I was going to change the external clock a
bit at a time and then test it for stability. Is this the wrong way to go
about this?
Could someone please explain to me what the CPU FSB / DRAM ration is? It
has me confused on a mathimatic level. 1 / 1 is the same as 2 / 2, or 6 /
6, so it being called a "ratio" doesn't help me out.
There is a CPU Interface option... could someon explain this and tell me
what it should be set at and why?
The CPU Core Voltage. Since I'm overclocking I'm going to be drawing more
current.. that's the reason I upped it a bit.. honestly I couldn't tell you
why I upped it only 1 and I would not be able to determine at what time, if
any, I should up it again. I'm watching my temperature's and atm they are
fine.
Should my AGP frequency stay at 66MHz? Does changing it speed anything up
or do I need to keep it matched or in ratio with something else?
Lastly, I understand how the CPU Internal Frequency is reached (clock X
multiplier).. but how come? 1 X 4 = 4, 2 X 2 = 4, and 4 X 1 = 4. Same
answer, different way's of getting to them.. is it better to change one and
leave the other alone for stabilities purposes? does one overheat the
system faster?
Again, thanks for all the help.
