1st Time OCer 3700+ Help appreciated

First time OCer. Thanks for this forum, I've learned so much. The 101 Tutorials Rock.

I have an Asus A8n-SLI Mobo
AMD 64 3700+ San Diego
Zalman LED Cooler Fan for CPU
Microstar 600W Power SUpply
Corsair Valueselect Ram 1 Gig
Geforce 6600 GT Pci-E x16

I used to use the program AI OC to OC my board but after several weeks of reading I tried to do it on my own.

Heres what I did so far.

Cpu - 260 MHZ
Multiplier x10

So far it all seems stable. CPU Temp is idle at 34C and FSB shows 1039. But heres my question.

Do I have to do anything with the voltage? I'm kind of grey on that area. I left it Auto in the Bios and Asus Probe II shows it at 11.65 V. Should I "not" leave it at auto in the bios?

I also saw in the bios that I can change PCI E Clock frequency. RIght now its at 100 mhz. Whats a good value for that?

Also Do I need to change timings on RAM? I don't know much about it so any help would be appreciated.

And how high do you think I can go for a stable load? Thanks so much for the help. As you can see I seriously need it.

cool thanks. ALso my HTT is at 3x but it can go high as 5x. Should I increase it?

HTT shouldn't go past 1000 MHz, 250*4=1000 MHz (perfect), if it goes higher the system might get unstable.

HTT is FSB
 
The odd thing is, with this mobo they said HTT or FSB I forget which could go up to 2000. Is it really 1000 or 2000?
 
They say it's 2000 MHz but actually it's 1000 MHz, it's a marketing thing.

HyperTransport, Lightning Data Transport
Implemented on AMD K8 series processors, this is, for all intents and purposes a bidirectional FSB but is clocked significantly higher. The base clock for the HyperTransport is 200MHz and the multiplier's go up to five. Factor in the principle of DDR and you get a maximum net effective hypertransport clock of 1000MHz (2000DDR). Naturally, marketers will often write this as FSB1600 or FSB2000 however this is incorrect as the actual clock speed is still half of that (marketers forget that DDR only means "effective") and that HyperTransport and Front-Side-Bus are mutually exclusive. Intel platforms do not have support for HyperTransport.

So is it ok that my FSB is showing at 1041? Should I make it higher? Bios settings are at HTT 3x, maybe 4x? Or would that make it unstable
 
Hey!

You should lower the HTT multi to 3X. At 4x (4x260=1040), it could cause stability issues. Always stay below 1000Mhz.

VOLTAGE: Definitely lower the voltage. Try a setting of 1.5V or 1.525/1.55. Try not to set 1.65...that's too high.

TRY: When you lower the HTT multi to 3, you can try a higher core frequency like 280 or something.

i disagree with jan
test it with prime95 first, (torture test, "max heat" or w/e) for about 24hours or so.
if its unstable, then raise voltage.
also, my HTT is at 1016mhz right now, and perfectly stable. most of the time it depends on the chipset.
i used to have it at 1200mhz, and it was unstable... but only if my computer was under full stress.
also, do the prime95 torture test which tests the RAM
if the "max heat" test is unstable, then you need to raise cpu voltage, or lower frequency.
if the "lots of ram tested" one comes up unstable (meaning an error occurrs) then that means you need to raise dimm voltage or lower ram frequency, or [set higher ram timings]<-thats what i did.
do NOT let your computer stay unstable, because it will restart on its own, at a random point... and then begin to happen more frequently.

Also my HTT is already at 3x, should I lower it to 2 and raise my core frequency?

For some reason, after a few hours it seems like my computer is a little slow. Like when I delete something from my desktop or open up an internet browser. Is the higher FSB the cause of this?

If I'm reading correctly, its better to Lower the Multiplier and raise the core frequency? This is in relation to FSB.

What I did now was raise it to 270 MHZ and Multiplied it x10. Still my FSB is now 1080 but it seems alittle better. Heat is holding steady at 35C
 
same thing, different combination. it really depends on the system configuration and the individual parts... and their specs.
 
I don't know if this helps but here ar emy parts.
