I am shortly going to wipe my hard drive and reinstall my OS(es). This
seems like a good time to make any changes to system set up without risk of
instability compromising my data - since I will have backed it all up and
can reinstall the OS(es) again if they should become corrupted.
I shall detail my machine specs at the bottom of the post.
So, I am wondering about the following:
PCI Latency - in the past I have used as high as 160 and as low as 32. This
board allows me 32, 64 and 128. I'd be very interested in what factors have
caused experienced builders to choose one setting over another as I am
looking to set it to the optimal for my system, obviously and any factors
you have found which impact on it or are impacted by it are of interest.
Memory timing - It is my understanding that CAS latency, RAS to CAS delay
and RAS precharge should all be as low as can be achieved stably. RAS
activation however I am less sure of.. obviously too short is not good, but
is it optimal to set it as long as possible?
AGP - has anyone noticed any real performance gains from an out of spec AGP
bus? I have frequently had mine out of spec, sometimes as high as 80 Mhz
but I am not entirely convinced one way or the other and would be interested
in experiences and theory from others.
I have always aimed to have my FSB as high as possible even at the cost of a
slightly lower effective CPU speed, rather than have a higher multiplier at
a lower bus speed. Do you agree this is correct trade-off when
overclocking? If not, why? Indeed, if so, why? LOL
OK, system specs:-
AMD Athlon XP 3000+ cpu
Gigabyte GA-7NNXP m/b
nVidia FX 5600 gfx
2 x 512Mb DDR-400 branded mem.
Maxtor 160Gb SATA-150 hdd
Pioneer 105 DVD-ROM
MSI 52x CD-RW
FSB is 202MHz, CPU has 11.5 multiplier (2323MHz)
FX 5600 is stock nVidia part and timings on 82MHz bus
(Core 325, Memory 400)
Memory is obviously "DDR-404" as it were, timing:
CAS 2, RAS to CAS 2, RAS precharge 2,
RAS activation 8, i.e. 2-2-2-8
SATA Controller is Silicon Image 3112, drive is first channel.
Pioneer is RPC-1 (BIOS 'fix'), MSI is stock.
Well, that is a pretty full description of my system.. I hope I have been
clear enough in what I am asking, I look forward to your input ;¬)

P.S. I am not a novice I just would like the benefit of your experience to
add to my own, especially on the areas where I have no clear 'optimum'
