AMD 3000+ E6 help

post #1 of 16
Thread Starter 
i have overclocked my cpu from 1.8 to 2.6ghz with 8x325 and my memory at a 266 divider. i have my cpu set to auto voltage and is currently running at 1.488 volts. if i go any higher i can't have a stable system and if i up the multiplier then it won't be stable even when i bring the fsb back down. i'm thinking it's my voltage but i'm not too sure. i'm really trying to get 2.8ghz but i seem to have hit a snag... any input would be great and tons of reps

You can try taking the Vcore off auto and pushing it over 1.5. Your temps should be just dandy with that Big Water.

VCORE is best not to set as "AUTO" because of two problems:

1. CPU becomes highly unstable due to not-so-absolute voltages. Thus, it is recommended that you set it by yourself and give it a few tries and find the true stable voltage yourself.

2. When you overclock higher, there is a possiblity that the computer does not boot into Windows safely. I have gone quite high with my 2.66 Ghz P4 Intel, and the computer could not boot into Windows very well. Why, I almost corrupted my Windows.

The second reason probably links up with the "unstabilized" issue, but I wanted to be specific.

Thus, the main reason that you shouldn't set VCORE to "AUTO" is due to unstable system. The voltage is set lower than necessary, so you get a very unstable system although the computer seems to boot well.

I hope this answers some people's questions and please correct me if I'm wrong.

hahaha i was looking around and i found this! haha i'm gonna try to boot up with 1.5 or higher and see what is up.

Voltage issues... sounds like poor PS performance.
A good stable PS is the most often overlooked cause of instable OCing.
You should have atleast 24a on the 12+v rail for a single card sys like yours... 34a with duals if you ever intend to do Sli!

Also, disable CoolnQuiet when OCing.

yea, that power supply is definelty a problem...just hope one day it doesn't fail and take a couple components with it. As far as your OC, here's some settings I would recommend..In this case I am going to recommend the .5 multi, because of your memory situation and this might be the only way to get it running that quick. here we go..This is for 2.7ghz.

318x8.5
HTT x3
Mem divider 266 (133)
vcore 1.55-1.6 (try 1.55 first, then 1.6 if it doesn't boot)

If this doesn't work, it's your vcore not being high enough. If it does, then I will try to get you to 2.8
DONT push the vcore until you report back.

Try 2.7 with 300 x 9.

that will only work if he slaps a massive divider on, and in this situation his memory will be running around 193mhz. My recommendation was for his memory to run close to 208, still within the range it is operating now..with some more headroom...the only way you are going to get anything different is buying new memory.

well i just tested it out... i have it set at 330x8 with ram at 266 running at 440. my v-core is at 1.520. i did the super-pi and was able to do 34.922 with the 1mb calc. i'm pretty sure it's my power now... i did boot from 9x300 but my ram and ht were really really low... i can't set up a divider between 333 and 266. i'm probably going to have to pick up a new ps or i can dual boot off of another one i have just sitting around here... is there a guide to show me how to dual boot? i thought i saw one earlier.

ok well it boots up just fine and does super-pi. i'm going to try 330x8.5 and see if that is going to be stable....
