Installing OS with overclocking...???

I am going to build a P4 2.6c/Abit IC7/Buffalo 512MB PC3200/Antec SLK3700AMB/etc system pretty soon. Anyway, from what I have read (from many sources) people hit 3.25GHz with this setup (or similar ones with 2.6c's). So lets say I hit 3.25, or even 3Ghz. Should I install the OS (windows xp pro) before or after overclocking? Or should I install on an old HDD, install XP, o/c, stresstest, then install XP on my regular HDD (while having the overclock)? Does windows setup make any "optimizations" depending on CPU speed? I know that installing an OS with a unstable O/C is bad (from reading and experience...cough AMD K6-2 450@550 cough - damn i had that CPU smoking after a while!!!), but if my O/C is stable (and if it isnt stable I will run at stock speed), is it ok to install while o/ced? Thanks, Josh
 
To summarize my post better, here are the questions I have:

1. Should I install Windows XP before or after overclocking?

2. Does Windows XP setup do any optimazations based on CPU speed?

3. Should I install XP, overclock and test, then reinstall XP?

After reading my first post it is really confusing, so I narrowed it down to 3 yes/no questions. Thanks in advance, Josh

I've always found that it's best to overclock before installing windows, because it's a good way to find instability. You overclock, if windows doesn't install, something's wrong. If windows installs, then go ahead and run other stability tests.

Yeah I was thinking that also. I need my system to do EVERYTHING while overclocked, and if it can't, then it wont be overclocked!
 
No. You want to install on a completely stable system, that means install when running at stock speed. Running overclocked, your install might finish, but there could be non fixable errors that you wouldn't know about, which could lead to instability when you do get your system overclocked.

As for your questions- a windows xp install is the same on a pentium 1 or pentium 4, so:
no, no, no in answer to your questions.
 
install
oc slightly
"burn in" with something lik eprime 95 or anything that can keep the cpu at 100% overnight

reboot
if it still works...then try harder to screw it up, then when it screws up...take it down half a notch and leave it alone.

<----- went up 2 notches at once, pc no likey me now
 
1. Install on default speed.

2. No, it doesn't optimize

3. No, install, overclock, burn it in, maybe overclock more...


Since you're trying to be cautios.. install the recovery console, be sure you're using ntfs, do a system state backup before the overclock. That's about all the precautions you can take with your OS. It's your hardware you should worry about 😉
 
Do not overclock at all when installing your OS. Overclocking before installing the OS is a splendid way to introduce small errors that you won't be able to detect right away, but that will just annoy you from time to time and cause general instability for seemingly no reason at all.
 
Running overclocked, your install might finish, but there could be non fixable errors that you wouldn't know about, which could lead to instability when you do get your system overclocked.

I think I get what you are trying to say here, but the wording doesn't make sense. The way you worded it says, if you install when you are overclocked it might install but then you may have hidden stability issues when you decide to overclock. Well the decision to overclock was made before the install not after so there is no "when you decide to overclock" it already been done.

No, when you install with a system running out of spec, something can get screwed up, which will cause spontaneous problems whether your system is overclocked or not.
 
I'd install it overclocked.

If errors come up while installing or come up after being installed, then you know your O/C is not stable and you probably won't be able to run your "everything" on it anyways 🙂

And no optimizations by O/Cing and installing.

NM. The context of his wording is messed up. I think I know what is is saying though.
