What is a Safe PCI Overclock ?

Mine's at 34.5MHz....PCI at 103.4MHz

Fine or Bad ?

 

PCI-E should be fine with anything from 90Mhz up to 110Mhz and PCI 30 to 36Mhz, without f***king anything up! Recommended is 101Mhz for PCI-E and 33 for PCI.

 

How can i check the correct PCIE & PCI frequency (except SetFSB) ?

 

Oh, alright. Dang, I posted them the other way round.

The PLL registers are screwed up some how. Default is 33.3. Once OCed I can't set anything between 25.9 and 34.5.

PCI-E: 77.8 and 103.4

PCI frequency at 34.5MHz - will it affect the HDD ?

 

34.5Mhz for PCI is fine! You'll notice kinda quick if it works fine or not. You can think of it like a FM-radio frequency, that the PCI-E has the best connection via 101Mhz and PCI at 33.3Mhz (i forgot to add .3 to the PCI clock in the previous post hehe).

I'd say that you're very safe with 34.5Mhz (you'd see if anything is behaving odd, or in most cases get a blue screen when it's too high/low)
I've myself has been running the PCI at 40Mhz for a long time back in the days, it worked fine, but anything above that and everything got ****ed up with the HDD's, only corrupted data though, but that's not funny on the OS-drive.
You can go a little higher than 34.5Mhz also if you'd want.

Also use 103.4 for PCI-E if those two are your options, you should be fine with all the values between those that i said in my first post without anything happening at all, worst case scenario for PCI-E is that you will just suffer some performance loss on the GPU, nothing will break though.

You'll notice pretty fast if it's not working

 

All systems use 100 or 101Mhz on the PCI-E and 33.3Mhz on the PCI.

SetFSB tells you what the current value is set to, right?

 

Awrite. Thx for the info Michel.

I didn't really want to play around with the PCI freq, but OCing the FSB caused PLL register screw-ups and all. Running at FSB 190MHz and PCI 34.5MHz, no problems yet.

 

are there any noticeable performance gains with an increase in pci-e frequency?

 

No problems

Yeah that's one of all the things that can happen too!
I think it'll work just fine for you with that!

There could be, but no.
I've heard ppl saying that there is. But has explained the gain as you fast forward a movie. If you know what i'm saying.

 

Why would you want to overclock your PCI slots??

You don't really get any performance increase... you only risk damaging your components.

 

No, You wouldn't wanna do that

 

Actually. I had some problems with those hexadecimal registers....Like 7F is PCI: 25.6MHz, and then it goes to value 80, and not value 00 (for some unknown reason) [default hex value is 63, which doesn't work if manually set in the diagnosis window], so I have to set the PCI PLL register at 80 which gives a PCI freq of 34.5MHz, and also increases the PCI-E freq to 103.4MHz....

Keeping the PCI at 25MHz makes the system a bit buggy. And it was fine at 34.5MHz and I was worried if the increased frequency would cause data corruption on the HDD.....(Which is the last thing I would want, since my external is also dead atm )

 

When you increase the FSB(overclocking your CPU) your PCI and PCI-E clock will go up(or use another ratio) along with it, if the BIOS cannot lock those frequencys at it's default values (as all desktops can do today for example, and that's why you can achieve very high stable overclocks today on desktops for ex, comparable to several years ago).

Just wanted to tell. If someone wants to know why it is like that and why you have to overclock the PCI/PCIE clocks, you don't wanna do that with purpose(atleast not to much/less) if you don't gain any other performance (like a higher CPU clock)

 

oh, ok that makes sense. It's more for system stability on a whole, than individual performance increases.

 

andy, now why are you overclocking your laptop?
Dont you realize overclocking is a bad idea

Aah yes. Overclocking is bad....!!

Seriously !!

Winlogon terminates itself about every hour or so, and explorer restarts. Dunno whats causing it, but laptop runs fine without OCing.

I have a T7600 ES with an unlocked multiplier, but I can't install it. Still have that ****in' screw jammed into the LCD Hinge.

 

remember andy, good things take time. You cant rush computers or they will bite back
at least yours still works
mine still doesnt
School has been so busy I havent even touched it in at least 3 weeks.

You should backoff the overclock a little and check northbridge temperatures, they may be causing teh system instability.

Aye, right. What system do you use now ?

NB Temps are good.
The one sensor that controls the fan never crosses 85*C, without lowering the voltage (at a ~50% OC).

2.3GHz really helps in Video-Encoding/Editing.

 

i use my dell e1505 it is way more reliable than my voodoo ever was. That is why I want to get a faster processor for it, so I can give her a little reward for being a good girl.

just dont push it to far, or you have 0Ghz
