Guest EFiNi7 Posted May 8, 2006 Posted May 8, 2006 Im new to this forum and DFI products all together. I must say i am extremely happy i made the switch from my ASUS board to DFI as it has given me the ability to clock my PC to the max and use my BH5 sticks to their full potential. However i have hit a wall with my CPU speed at 3GHz. I have a feeling she has more in her, but i believe that the chipset is holding back. I have increased it to the maximum voltage the motherboard allows. What i wanted to know is if there was a mod you can do to the board to get more voltage to the chipset???

Lackadaisical Posted May 8, 2006 Posted May 8, 2006 I think you have hit the limit of your cpu. You already have it running at 1.8vcore thats dangerously high... Quote Share this post Link to post Share on other sites More sharing options...
Oceanborn Posted May 8, 2006 Posted May 8, 2006 If your HTT is at 270 as your sig suggests you're nowhere near needing ANY chipset voltage increase as these boards can hit 300HTT without breaking a sweat.... To prove my point....try and decrease the multiplier of your CPU to something like 5x and then see if you can get past 270HTT....I can garantee you will.... PS: at 1.8volts your CPU will either die soon, or have a very short life span.... Quote Share this post Link to post Share on other sites More sharing options...
Guest EFiNi7 Posted May 8, 2006 Posted May 8, 2006 What is the maximum vcore voltage i should be using then? If your HTT is at 270 as your sig suggests you're nowhere near needing ANY chipset voltage increase as these boards can hit 300HTT without breaking a sweat....To prove my point....try and decrease the multiplier of your CPU to something like 5x and then see if you can get past 270HTT....I can garantee you will....

225Slant6 Posted May 8, 2006 Posted May 8, 2006 Most people run 1.65v max on the voltage to the core. I run 1.45v through my core. Quote Share this post Link to post Share on other sites More sharing options...
Guest EFiNi7 Posted May 8, 2006 Posted May 8, 2006 I was under the impression that as long as the temps were reasonable i could pump as much voltage as i want. With 1.8 volts, my vcore idles at 25 degress celsius and on load max out at 51 degress celsius at the most. Quote Share this post Link to post Share on other sites More sharing options...
Guest caffeinejunkie Posted May 8, 2006 Posted May 8, 2006 Correct me if Im wrong but im pretty sure that not much more than 1.7v begins to kill the on-die memory controller The highest ive ever run is 1.6v and that was a 3250mhz suicide run Quote Share this post Link to post Share on other sites More sharing options...
SquattingDog Posted May 8, 2006 Posted May 8, 2006 Correct me if Im wrong but im pretty sure that not much more than 1.7v begins to kill the on-die memory controller The highest ive ever run is 1.6v and that was a 3250mhz suicide run I have also heard about this. I ran 1.85v thru mine on a suicide-attempt to make it to 3ghz. No go. Settled for 1.75v @ 2.8ghz on air...never seemed to kill the mem controller - didn't like my chances tho - so I dropped it back to 2.5ghz for day-to-day usage and 1.425v. This is something I have heard (applies to 130nm): "every 0.1v you increase the cpu past its default will half its lifespan. Normal CPU's silicon has an average lifespan of 16yrs, so to up by 0.4v is to basically do this: Lifespan = 16x(0.5^4) = 1yr." This is due to degradation of the chemical bonds between the silicon molecules. They get ionized faster at higher voltages (or something), and apparently on smaller die cpus (90nm like your San Diego etc), this happens quicker, so an increase in voltage by 0.1v probably reduces lifespan by something approaching 65%... Anyway, its up to each user how they treat their gear, if you're happy with it at 3ghz (hell, I'd personally be overjoyed, esp at those temps), then stick with it - but just keep this info in the back of your mind . Don't say you weren't warned that upping the voltage is bad for the CPU. Quote Share this post Link to post Share on other sites More sharing options...
3stars Posted May 8, 2006 Posted May 8, 2006 on the same thread i'm getting 2.9 @1.644 (not quite prime stable)i was about to go up just a slight bit to 1.6588(1.45 X 114.4%) to give me satbility i've got crap ram so i'm using a divider just a smidge should be ok any thoughts. ps im on 1/2" water with great temps 25@idle 30sih@load ambient is 17 also these boys on phase and all that are still killing there cpu right???????

Guest EFiNi7 Posted May 8, 2006 Posted May 8, 2006 you have a good point there. About people who use phase cooling still killing their cpu using high volts. It would be interesting to find out. What htt, multiplier, memory divider you using? on the same thread i'm getting 2.9 @1.644 (not quite prime stable)i was about to go up just a slight bit to 1.6588(1.45 X 114.4%) to give me satbility i've got crap ram so i'm using a divider just a smidge should be ok any thoughts.ps im on 1/2" water with great temps 25@idle 30sih@load ambient is 17 also these boys on phase and all that are still killing there cpu right???????

3stars Posted May 8, 2006 Posted May 8, 2006 i'm using 264 X 11 @2904 Mhz ram @ 207 2.5-3-3-6 166 divider i'm waiting on the deal for some xtreem micrin b5f ics on a deal from nintek http://www.nindeals.com.au/showthread.php?t=19 i'm just trying to find out what they do i've heard of ddr600 so that would be nice put this other stuff on ebay Quote Share this post Link to post Share on other sites More sharing options...
Guest EFiNi7 Posted May 8, 2006 Posted May 8, 2006 Im using 290 x 10 with ram at 241 @ 2 2 2 7 1 - 5:6 divider. Currently priming. My ram is OCZ OCZ RAM BH5 gets up to 255 @ 2 2 2 7 1 at 3.4 volts pushing 7GB - BH5 chips Quote Share this post Link to post Share on other sites More sharing options...
