Overclocked and Encode?

[Antknee]

My computer is as stable as when it was at default speed. No crashes, no lock ups. But for some reason, when I'm encoding, I usually get an error or two. Does TMPGenc have a TSR (Termiante and Stay Resident)that monitors default CPU speed for encoding? None of my other applications or games give me any problems, no matter how intensive the CPU usage is. Any thoughts or ideas? :confused:

remove your overlock, and if you still get problems lower your memory timings.

Hello??? NOTHING you will normally do will overtax your processor like video encoding. This is the reason you can overclock your processor while running other programs and not have any problems - the CPU has plenty of time to literally cool down. Not so with video encoding - your processor will run at near 100% for the entire encode. For a 3 pass, 2 hour VBR encode at say 1x, this is 8 hours at maximum speed.

This is why the vendors put a maximum speed on their products.

BTW, your CPU TEMPERATURE you show below is while the thing is basically at idle.

Help is not replying to someone like they're stupid, but anyway, I'll let your comment speak for itself.

I think I know by know how much my CPU usage is during encoding since I've been doing it for a while, and how long it takes.
BTW my CPU temp is never above 90.4 even during encoding, so temp has nothing to do with it.

But thanks anyway....

i also have an o/c system :D pretty much like you have.
the same model P4 and the same speed 2.7 Ghz and it works fine.
i've used to transcode some movies and no problem at all.
what i think is that if the temp's don't go too high you can even run it at 3point something ghz and still have no probs. like some1 said memory timming is also very important. so you can do several tests. try lowering mem timmings since dvd encoding is not really memory intensive, (i think!!!)
my cpu reaches 45 celcius (don't mind the spelling) so that really is not a problem...
hope you solve your problem.

there's also the case that some programs may not work well on o/c systems but that is the proggys fault.
i remember i once had a problem with 3dmark 2001 running on my old willy at 1.5 no o/c the only thing that was working overclocked was my gfx card. it messed up the proggy really bad as i could never enter the program again.

oh.. my gfx card as the sig says is o/c to 320/660.
in your "quest" to find the problem try only one change at a time. as it will be easier to detect the problem.

sorry for the very long anwser...:) :)

[destemido]

shit... i didn't see all you system spechs before posting...
you're on sdram!!!! dude unless you're using top quality brand sticks... don't o/c using that memory. not to mention it is holding your system performance down, big time!!! you should use if your mobo allows, DDR memory. you can achieve mad o/c's using that memory type.

[Antknee]

Sorry Destemido,
That was a typo. My Memory is DDR SDRAM PC2100.
I need to change my profile. :rolleyes:
But thanks for the info!:D
Do you think I would still need to lower memory speed with PC2100DDR?

[destemido]

i don't think so... but you can try, won't hurt right??
pc2100 runs at 133 so running at 150 is ok even in "no brand" sticks...

[auenf]

and your PCI bus will be running at 37.5mhz, which wont be happy for your cards/hdds

Enf...

[destemido]

yep but no problem here.
even at 38 Mhz like i run mine that shouldn't be a problem.

[Antknee]

:D I found the problem. I didn't have enough voltage to the CPU. I upped it one notch (.10) more volts, and it encodes just fine!

13hr encode time.:D

destemido, how long have you been running your PC OC'd?
I do hear about PCI devices and HDD's not liking being OC'd...
You haven't had any damage or performance loss??

[destemido]

my pc runs just fine
of course i could also run at 150/30 but since the performance is +/- the same... i keep it like this.
i always run my pc like that. and to top it all i can run mina at stock voltage. to bad i'm with an asus p4t533-c otherwise i could go higher than 150mhz FSB.
i've heard the best p4's for o/c come from malaysia.
mine is one of those. this mobo is really holding me back. even the ram (pc800-45 ns) can go up to 1136 Mhz and remember they are supposed to run at 800!! now i have a stick of pc800-40 ns. now i wonder how high that can go!!!

[aftertaste]

13 hrs WOW that seems a bit much for a 2 pass encode. Esp. with a machine like yours. I run a 3 pass encode (actually 4 passes) with settings simular to yours. And yes i run Inverse Telecine also. And i get most movies done within 9 - 11 hrs and that includes everything Decrypting, Demuxing, VirtualDub, CCE, Pulldown, and burning in not so many words. And although my system is dual processor it is still much slower. Sense i am a bit of a newbie i am just trying to understand why it is taking you so long to encode with a machine like that.

ahh, so your computer wasnt as stable as when it was at default, until you put that extra .10 on there.

and you wonder why i keep telling people to remove their overclock ;)

Enf...

[destemido]

you know... not all mobos behave like that... even a same speed CPU can behave diferent just becuase it has been built in a diferent location. it is said that p4's from Malaysia are better than those from Costa Rica.
but if it really takes that long ... you should check you cooler to make sure your CPU is not "Throttling" (for those who don't know, it a technice or a feature that will reduce the CPU speed as the temperature goes up so that the CPU won't burn.. meaning a p4 at 2.4 Ghz when o/c could run at 400MHZ in throttle mode... if it heats too much)
a p4 @ stock can run quake 3 without cooler at all, a thing the AXP's can't do... but don't start calling me a Intel Fanboy... i'm just pointing this out...

[Antknee]

auenf seems so negative about people succeeding at overclocking...
I wonder why?:rolleyes:
Anyway...You shouldn't jump to conclusions...before you open your mouth, I upped the voltage only because of errors that TMPGenc was giving me, not any other application on my computer.
So yes, it was still stable, it didn't lock up or crash, or reboot.
So I'd say you're wrong.

All you've done is be negative, instead of trying to give some helpful advice. You sound like you work for Intel..."oh no no no, you shouldn't overclock.."

ahh, so your computer wasnt as stable as when it was at default, until you put that extra .10 on there.
