crashes when OC'd

[snypercore]

ok i have an AMD 64 3800+ venice 2.4Ghz. ive OC'd it to 2.7Ghz and it runes fine, i had to up the voltage a tad but temps never ever exceed 50 degrees celcius and i have very sufficent case cooling while the cpu has a stock fan.
at 2.7Ghz i sometimes get crashes pretty random, it will be fine for an hour then crash sometimes only last a few mins. whats causing this ive been bench testing it, temps are fine volatage is fine im lost, and also venice chips require little power, that and i have 550watt PSU with not much energy sucking hardware so it should be fine?

You might have to up the voltage a little more, to get it stable. And I would recommend aftermarket cooling. Like an Arctic Cooling Freezer 64 Pro. What is the vcore voltage, currently at?

thar ya go

EDIT: there was ment to be a pic ill get the link now...

do you seriously consider upping the voltage more than that? (1.504v)

alsoi will invest in aftermarket cooling but till i can aford it my cooling seems ok i mean if i leave core temp on system tray it will create a log, if i then go and play a demanding game (supreme commander) i can go back and check the log and it stay in the low-mid 40's

i wouldn't up the vcore too much more. you only have a 25mhz increase on your fsb..shouldn't require much of a voltage bump.
post the "memory" tab of cpu-z. your ram is likely the culprit. what mobo do you have?
alos, drop the ht multi to 3 (right now it's at 4), this may be causing an issue with stability as well.

those temps make my quad seem like a hotplate

MY ram was OC'd to so yeah could be the prob. im nothome at the moment so cant post aCPU-Z screeny till i get home, im pretty new to OC'ing so what your saying is kinda goin out of my league but im sure i can learn.

my ram is DDR400 1GB and is running at 233MHz i dont know anything about timing and stuff and i havnt touched the voltage of my ram.
my mobo is an Elitegroup nFORCE3 A939, it specifically has OCing features so its pretty handy.
i might add i have made a very small OC on my GFX card (ATI X1950 AGP8x 256MB) in the bios it was set to 66Mhz ( cant control the multiplyer) to 69 Mhz thanks in advanced ill post back the screenies later

[Nagasama]

so if it is running at 233 mhz, it is overclocked 33mhz. what kind of ram is it?
it may not like running over stock at all, or it may need a small voltage increase.
try dropping it to ddr333 and see if it will stabilize.

i OC'd my RAM a long while back beofre i started OC'ing anything else and itsbeen fine.
all i can tell from here (not at home still) is thats its DDR400 @ 233MHz, havnt touched the voltage, my bios has the option to up the speed to 250 but it wont boot so itmust need a voltage increase but i dont know how much to increase by so maybe you could tell me, the chips are samsung and thats about all i can remember till i get home.

thanks alot for the replys ill son get the CPU-Z screenies up later

also i havnt touched the timings n the other sections ofthe ram as i dont know what they do and any web page that explains how and what seems to advaced so maybe someone could fill me in there to
