How are these voltages and settings?

I've been playing around with my BIOS, trying to balance performance and
stability, and I think I have a good combination, but I want to get some
advice from more experienced people on if I've done anything to play with
fire (beyond the danger simply inherent in playing with one's BIOS).

I have an Epox 8RDA3+ (NFORCE2 Ultra 400),
AMD Athalon XP 2800+,
512MB PC3200 DDR400 RAM
ATI Radeon 9600 XT

I can't change the CPU multiplier, so when I change the board's FSB to 200,
the CPU id's as a 3200+. Which from what I've read is just fine.
So I have the FSB at 200MHz (400MHz), the RAM "at speed", and the following
manual adjustments:

AGP bus: 75 MHz
CPU voltage: 1.73 v
AGP: 1.80 v
nForce: 1.60 v
Memory: 2.76 v

My Epox system utility seems to indicate the AGP and RAM voltages may be a
little high. Opinions?
My case temp never gets above 38C, and I've not seen my CPU get above 45C
even while doing an SiS burn-in. But interestinglt, SiS is detecting "board
temp" at 53C even though my BIOS, my System Utility, and SpeedFan all don't
see this 3rd temerature. Is this a problem?

I'm tempted to up my mobo voltage a little since it needs to be sure to have
enough power to be stable since it controls everything, but it's also
argueably the most sensitive to over powering. Opinions?

Any advice or suggestions or opinions are greatly appreciated!
Thanks,
Liam

Actually it's not anywhere close to right. Assuming this is a Barton core,
the default multiplier is 12.5, so that would put the cpu at 2500MHz,
considerably faster than a 3200+ (2200MHz). More like a 3400 or 3500+.

Nominal AGP is 66MHz. You can fix this using the PCI/AGP I asume. To get
2500MHz with that little CPU voltage is very good. I think AGP default
voltage is 1.5v, so that does look pretty high. Don't know what the
default of the chipset is.

Default ram voltages vary depending on the ram. Some are 2.5v and some are
2.6v, so it depends on what the default of your ram is as to how much over
it is.

Not sure what you mean here by MB voltage, maybe chipset voltage. I try to
keep all voltage increses within 10%.

Uhm, well, all I can tell you is that when the PC boots up at 200(400)MHz
FSB it detects the CPU as a 3200+, when I run SiS it detects it as a 3200+,
on My Computer's properties, it calls it a 3200+. =)
I think the mutiplier is 11.

Sorry, mobo=motherboard

APG bus really needs to be at 66 MHz and 1.5v (in spec), if you want to
overclock the Radeon use Riva Tuner software.
That is a nice 1.73v for the cpu you might try to lower it and see if the
system will remain stable 1.65v to 1.7v, use prime software to test
stability. You could leave the core voltage at 1.73 and try increasing the
FSB and test for stability. Remember use small increases in voltage
(±0.025v) and test. Only increase the voltage if the system becomes
unstable. The max for AMD spec is 1.85v.
The Nforce chip set default is 1.5v alot of MB manufactures have the BIOS
default set to 1.6v for the Nforce chip set (Abit, Asus). 1.6v sounds OK if
that is the BIOS default for the Epox 8RDA3+ would not go any higher than
1.7v and only if you need it at FSB frequencies >200. North bridge chip get
hot above 1.6v and you could ruin your MB.
The 2.7v on the memory is most likely within spec but I would not go over
2.8v.

BTW the memory should be running at the same frequency at the FSB 1:1 ratio
or 100% of the FSB. If the memory becomes unstable at higher FSB
frequencies increase the latencies.

ver gets above 38C, and I've not seen my CPU get above 45C

This is the core temp reading from inside the cpu and will be 6°C to 10°C
higher than System Utility, and SpeedFan.
As long as 53°C is a load temp should not be a problem. In general any core
temp over 60°C will decrease the system stability. CPU will not be damaged
until core temps exceed 85°C, although I would not let them my core temps
get over 70°C.

Then you don't have a 2800+ as you stated. The 2500+ has a default
multiplier of 11.The 2800+ is 12.5 and if locked with a default FSB of
200, it's not a 3200+, even if that what's your bios reports it at. You
need to understand that the bios determines whats displayed by cache size
and clockspeed. The code may very well be written to display a 3200+ with
any speed over 2150MHz, and since there is no official 3400+ then it uses
the higher one.

OK, I have a 2500+ then. It's been a while since I've seen the exact number
stamped on the chip which happens to be under a heatsink at the moment. =)

Thanks for the claification.
