question about bios settings options

[edub2006]

ok im trying to make my board more stable im looking around bios and i found this 3 things that i have no idea what they do. So beforei went in there and meesed things up i wanted to see if i could get some answers.

1.Pci express clock (its at 100mhz now ) up it or leave alone?

2.pci clock sync (auto,to cpu,33.33)

3 ht voltage (at 1.20) up it or leave alone?

HTT . i have read if OCing set to x3. how come? cant i put it at x4 or x5?

Leave it locked at 100MHz

Definitely leave this locked on 33.33MHz.

You shouldn't have to adjust this voltage. You can give it a shot for testing purposes but I think you'll see no benefit from raising it.

Set HTT mult. at whatever number that when it multiplied by the HTT speed you get closest to 1000. Try not to exceed 1000 if at all possible, instability can occur when HTT is overclocked. Some boards do better than others in this regards though. My A8N-SLI Premium is good to about 1100 so far, but I run it less than 1000 when I'm not playing around.

What board are you using by the way?

asus a8n sli prem

just leave it at 3x if you go above 250HTT or leave it at 4x if you stay below 250HTT

so whats the purpose of them in bios then?

I have the same board. The HTT mult. is there for you to tweak as needed. As Shimm said, at 250 and below, select 4x. Above 250, go with 3x. The deal is that you should strive to keep your HTT speed at or below 1000MHz.
