Crashing When Transcoding AVI on OC System

[ekb606]

OK. got a QC6600 system with 6gb of Crucual 800 DDR RAM oc'd to 333 percent (299MHZ on each core.) Have tried RAM at 1:1 ratio (667MHh) and 1:20 (799). Also have tried RAM with Crucial's specs -- 4-4-4-12 -- and with board's (Abit i38Quad) defaults which are I believe 5.5.5-15

OS is Win 7 RC 64

TCPU voltage is, I think, 2.0650 (or maybe 2.650) and RAM voltage 2.00 of 2.200. Am also running six hdds and twoDVD writers.

CPU temps are outstandingly good ... highest core is 39 as I write and everything -- including some very complex Photoshop and multitrack operations works fine OC'd except ...

The system won't extract a DVD and copy to a new DVD or video TS folder without crashing. Likewise, it will crash if I try to transcode AVI files into DVDS or HDD DVD files. I've tried more buring programs that I can remember -- Nero DVD Recode, Nero Viision,Sony DVD Architect, Adobe Preiemere Pro, Cyberlink Producer. etc. and the results are always the same.

The only clue I have gotten is one cryptic message from DVD Architect that the system crashed because the program was expecting the RAM and CPUto be running at specified speeds and they were running faster thus throwing the program's wirte timing off.

Does this make any sense to anyone?

Thanks

do you crash without your overclock on... as that will let you know what is going wrong with the hardware or software

Thanks, if I take the system all the way back to the board maker's optimal settings, it doesn't crash ... but that's giving up a lot of performance tweaks, not just OC'ing.

What's making me nuts is that it will process things like 12 track of high-res audio with live effects and rendering and all kinds of really CPU/ram intensive jobs in full overclock mode.

I'm wondering if I ned to somehow change the cache or other settings on the tmp and save to hard drives used by the video editing programs.

well first of all you'll need to fill in your system specs... as other members will want to see it to help you... heres a link to do that: http://forums.techpowerup.com/profile.php?do=specsn

sounds like an unstable overclock to be honest as transcoding an AVI file will most likely hit the cores 100% leading to max temperatures... have you tested your overclock with Prime95 or another stress testing application as this will show you weak points in your OC.
heres a link to prime95 32bit:

There is a 64bit version for 64bit OS's... just google it...
where are you getting your temps from as you need to use coretemp or realtemp to get a C2Q 65nm chips temperatures not the built in motherboard software... heres a link:

Run prime95 for a while with one of the above temperature monitoring programs and watch that all of your cores are indeed in safe temperatures and that none of the prime95 worker threads fail

well this is obviously your OC is not stable... processing live audio isn't a CPU intensive as you think...

try running OCCT linx and see if it passes the test or not... then you know if its stable or some bug that could be with dvd-rw or something

do you have the pci-e bus OC'd atall?

btw... saying your idle temp isn't good, you want to stress your cpu then find the temp under load...

btw what voltage you using?

 

[twicksisted]

TCPU voltage is, I think, 2.0650 (or maybe 2.650)

what is TCPU voltage? hopefully thats not your CPU voltage as you need to be running around 1.3-1.35v for that Q6600 chip to get 3ghz... 2 volts will kill it... fry it etc..

 

[jamesrt2004]

btw my cpu voltage is set at 1.36 for 3.2ghz.
my cpu vtt(i think its called that) is 1.35 (closest to cpu voltage)
67% ref voltage
ram @ 2.0
try ram timings at 5 4 4 13
thats off the top of my head...

southbridge i added 0.1V
and nothbridge 0.15v
(thats on abit ip35pro) so you have better north bridge on yorus so should need less voltage but try adding .1 to it so you know it's not that..

 

[ekb606]

Thanks you all, VIt voltage ranges from 1.1625 to 1.3250 according to Core Temp 0.99.4.

Under load even with ambients in the 80s, cores never go much above 55 -- which is interested, they regularly ran 45-60/65 in XP64, dropped to 32-50/55 immediately after I wend to 7 -- which coud, I guess, be core temp.

Will try fooling around with ram timing as suggested and let you know.

haven't oc'd the pci-e bus and haven't tried linx, but the CPU passes Prime95

where you getting voltages from in core temp :S? I don't see them

seems wierd if you can pass prime then and not encoding.

is the dvd drive sata or IDE?

if sata, do you have sata setting in bios to raid, ahci or ide?

 

[ekb606]

one of the drives is Sata (set to IDE) and one IDE, but the crashes usually occur before writing either during transcoding with AVIs or toward the beginning of writing when burning a DVD or saving to a Video-TS on hard drive .. do not have any problem buring data, ISO or music DVDs ... just video.

Getting voltages in core temp from VID: box under Platform ... it suddenly occurred to me that maybe the problem is speedstep, which I keep enabled to cut CPU temps when the computer is idlying ... it hasn't caused a problem with any other function or application but everything is different so maybe I'll disable it and see what happens.

Thanks
