Alright so I really am beginning to get a hold on all of this.....Another question and I am sorry for my ignorance but this is a lot of information to take in.....Ram voltage or kit voltage..How do I find that out? I have no idea how to do that.

Speedfan has it at 1.5V does that sound correct?

It should be printed on a sticker on your RAM, otherwise if not it would have been on the RAM packaging. Atlernatively you can lookup the part number for reference on Newegg or something. That you can find with CPU-Z.

Also, I do not recommend Speed Fan. Not very reliable. You're better off with HWMonitor.

And 1.5v for your DRAM is fine. That is the lowest this board will go for the DIMM slots. You can do 1.5 to 2+.

Alright so I am excited about this...I lowered the voltage and ran power95 and everything looks good...temps at 40 degrees and stayed there. Now I will try to lower the voltage more...

Does the voltage to the ram matter a lot?

So now I have underclocked it again and it sits at 1.35 and is still stable...should I go lower and lower?

It can depending on what you're doing with RAM, but not likely for CPU stability at the moment.

You say you underclocked? Do you mean undervolted? If you're stable at 1.3v, that's a great starting point, yes. smile.gif

Sorry haha it is really late. Yes I am undervolted haha. Good news!!! I am glad it is a good starting point. So once I find the lowest voltage then i go from x17 to x18?

First try just a half, 17.5, then test for stability. If good, move up to 18, if not good, bump voltage .025v and retest. smile.gif

A walk through would be amazing smile.gif
thanks.

If your cpu is a Black edition then use multi , cpu voltage increase in the cmos is little by little. understand one thing is if you have to get the highest stable clock speed with the lowest possible voltage and lowest possible system / core temps and thnx to all the guys here at OCN i am understanding a little better how OC works and what effects even after almost 20 years in the IT industry this was one of the first times that I tried OC'ing ever. Heck during the 8088/286/386/486 days there was only a turbo switch on the motherboard which we needed to connect to a switch on the cabinet smile.gif haha I remember how the RAM's were placed when we needed to troubleshoot the ram from the error during post we had to search the block of the drams smile.gif

check the phase of your motherboard in google search better to have something above 4+1 phase like 8+2.

Not having a lot of luck so far....I have been doing this all morning and I am still getting crashes at 18.....I will try to keep upping the voltage......hopefully it is stable soon.
