Remember, too many BSOD's will corrupt your OS, even if you think it isn't showing any symptoms of corruption- it'll still be corrupt. redface.gif
Especially if you have write caching enabled and Windows write-cache buffer disabled!

I can't agree more. I've been following this thread from the start and have to say GanjaSMK you've done the best anyone can do here, excellent job!!!

Here's a link to another very well respected member's thoughts on stability you might find interesting. I'm only sharing this to help make sure you understand how important stress testing is so please do not be offended. http://www.overclock.net/t/990229/stress-testing-warning/20#post_13127125

There are many thing to learn while OCing and the time it takes is something you just can't rush. Slow down, take a little time, and study the guides that have been linked previously.

I take no offense....It is very complicated and I keep getting tons of blue screens so something is definitely off. I will read all the guides tomorrow and see what I can do.

Alright Ganja I am starting to understand a lot better thanks to your posts.....I read a bunch already this morning and it makes a lot more sense now.

Another question though...So should I just be upping the HTT then since everything else gets effected by it? That is the part that is still clear as mud to me.

I hate to say it though but I am still doing something wrong.....Last night I did a stress test and 3 cores went 9 hours with no errors but core 4 had an error an hour and a half after starting.....What does that mean exactly?

Just so I am clear.....The main thing I want to work with at first is the HTT [200] because when I bump that it bumps everything right? So I should find the ceiling for that number and then start to work with the cpu multiplier ?

Let me know if I am way off base because I just read for 2 hours straight and I feel like I am starting to understand a lot more.....

yes you got it as you incress HTT the ram gose up as well as HT as well as NB as well as the speed of the cpueverything gose up as you bump the HTT up the only thing that dosent is voltage

Thanks...I really appreciate your patience in this thread...I know it is probably frustrating when you are trying to paint this picture for me..But I think I am starting to understand it bit by bit.....

Now I have ANOTHER question haha. In the one guide I was reading from this thread the guy says that the North Bridge Voltage should be under 1.2V but my mobo does not allow it to go under 1.3V i believe....then later on in the same area of the thread he talks about hoe the North bridge Frequency should be between 2600-3100MHz and that the voltage should not be higher than 1.4.....So that really confused me....Is the voltage supposed to be 1.2 or 1.4 or what lol.....Sigh

Next thing is....I am testing my ram now...I am basically starting from scratch again....I have it at 1600 and 1.64V and I have no errors running tests. Now Do I leave it at this setting or do I bump it up using HTT? That goes for everything...Do I leave my cpu at 3400 and bump it up with the HTT as well or the multiplier? Do I up the NB frequency with HTT as well or do I do all of these separately? OR do I test their limits all separately and THEN bump HTT until I get to the limits....? lol

Keep in mind that with the HT Reference clock (HTT or FSB whichever you want to call it) you'll reach a point where performance actually starts to degrade. It'll look like a bell curve if you were to plot it. Once you figure out that point then it becomes a balancing act between HTT, CPU Multi, RAM Multi etc. to see where your sweet spot is. My advice is once you know where you'll set the HTT which will as a guess off the top of my head for your rig will more than likely be around 220ish (just a pure guess mind you not gospel), then you should keep the RAM multi low so it's around 800 to 1000 and then start testing multiplier/voltage increases to see how far you can go. Make sure to have HWmonitor open so that you can keep a close eye on your temperatures. I don't remember what the temp threshold is for Phenom II so hopefuly someone can post the max temps on the core that you shouldn't go past. Once you've settled on your cpu setting THEN start adjusting your RAM clock and timings to find the sweet spot with that as well (that will also depend on the maximum capabilities of your RAM sticks too remember).

Don't worry about the NB frequency just yet. That should be the last thing you play with. Keep it around 2600.
post #79 of 98
Don't juice your CPU/NB too much or you'll zap the IMC with too much voltage and it'll get wonky. I tend to recommend staying under 1.35v; preferably under 1.3 even better.

It's always best to test limits first. You would usually try to find the max HTT you can adjust/bump with, and to do that, you would lower everything else and keep maxing your HTT until you find it's unstable.

I bumped up the HTT to 220 and it looks stable so far.....I tried 225 and it gave me a bsod.

Ya I read about the IMC and all of that I will make sure not to zap it.

So now that I have found a stable ram setup and a stable cpu setup and a ceiling for my HTT where do I go from here? I am still confused about the cpu multiplier....Do I just use the HTT to OC EVERYTHING or do I up everything bit by bit? The HTT bumps all of it so that is what is confusing. If i bump the HTT up it changes the cpu as well as the ram so thats what I am having difficulty with now...I understand how all of it works for the most part but I am still not sure what to use to oc in the end.
