2800 barton and a7v8x-x

Son_of_Thunder · Jun 30, 2004, 05:04 PM

i would like to overclock my xp 2800+, but i'm having some trouble with it. i've tried adjusting settings, both my multiplier and fsb...but it always gives me frequency errors. basically i won't even post and it'll wait for a while then reboot into bios and say it reset my settings to prevent a crash.

now i've read that my mobo doesn't allow you to lock your agp/pci rates or whatever, would this make a differance? any advice on what i should set my fsb and multiplier at?

please respond

the north brige cooler is poor and improperly attached at factory, I highly reccomend replaceing it!

what are your temps? voltages? what cpu cooler are you useing? what power supply are you useing?.

I have the same bard a with a 1600mhz duron in it o/ced to @2GHZ works fine for me

i'm using the default heatsink and fan that came w/ my barton, my powersupply is an offbrand that came w/ my case 415w.

my current multiplier is 12.5x...fsb is 166

i'm guessing i need to turn on overvolt huh?

Son_of_Thunder · Jun 30, 2004, 07:49 PM

ok i turned my fsb up to 185, and my processor is clocked at 2.31ghz, i tried going for 2.5, but windows would not load. do i need to up the multiplier to get that to load?

all i really want to do is get my ram to run at pc3200 speeds instead of pc2700's, does that mean i need to turn my fsb up to 200? and if i do that how to i get windows to load?

--edit--

i'm currently running my fsb at 188, cpu voltage is at the default 1.65, multi is at 12.5x, and my temp is 45 degree's celcius.

i ran it at default speeds, and my temp is 43 celcius, is it ok for it to be running 45-47 cel?

I would try to figure out max fsb before OCing the cpu. For example if it is an unlocked cpu you should drop the multi to 10x and raise the fsb slowly to 200 to see if it can handle it. You will have to raise the memory voltage for sure if you have PC2700-up to 2.8v should be safe. Also with a board without locks the 188 you hit is super(I could only do 175 max with my A7V8X). But once you find the max fsb you can run at you set it at that and work the cpu multi. You will need to raise the voltage to get a desent OC though.

i don't know how to unlock a barton 2800+, i've heard most times that it has to do w/ your mobo and not the processor now.

whenever i touch the multiplier it simply won't post...no matter what. and i have yet to reach 200fsb, the highest that would boot was 195, but it needed to boot in safe mode...193 booted fine, but it would hit the 50 degree point too often and wouldn't run all the way thru 3dmark2k1 w/out shutting down the program. to reach 193 i had to turn my voltage up to 1.75 from 1.65.

also my ram is pc3200, i just didn't do my research before i bought it in conjunction w/ my mobo and processor.

well, that's the story so far...i hope it all made sense

ps, i plan to sell my mobo to a friend for around 30 bucks...and then i'll pick up an nf7-s V2 for $80, i hear that's a great OC'er

dipstick · Jul 1, 2004, 11:37 AM

Yeah, I don't really remember how things work with that mobo. But 193 is not bad at all for a VIA, if you can get a NF2 board I'm sure it'll do better. Did you raise the cpu voltage to hit 193?

yep

simple oc is set your mult at 11 fsb at 200....that's an instant xp3200

. Raising your voltage is indeed necessary for OCing. The higher the multiplier, the higher your voltage needs to be. My xp2400 is at 2.26Ghz right now.....my set up is 13.5x166 @ 1.725v. 11.3x200=2.3Ghz; 12x200=2.4Ghz; 12.5x200=2.5Ghz. Remember to increase the voltage a notch every for every 0.5~1.0 you increase the multiplier.

Increasing the voltage allows for stability, however, by increasing the voltage, you also increase heat. If you have stock cooling, or something you bought for $20 or less, spend at least $50 on better cooling. Thermalright has an awsome heatsink; but heatsink alone, you still need a fan. Get a Vantec Tornado to go along with the heatsink. These two in combo w/each other are the best air cooling set up you can get for an AMD. Remember thermal paste is also very important!
