hardnrg Posted March 17, 2008 Posted March 17, 2008 yeah 450 is 1800 Quad Data Rate (QDR)... I run 1825 atm, so it's 456.25 MHz base clock, with the memory sync'd it runs at the same base clock of 456.25... the Double Data Rate (DDR) would be 912.5 Share this post Link to post Share on other sites More sharing options...
xPETEZx Posted March 17, 2008 Posted March 17, 2008 Right ok, So I understand all the CPU bits now. Moving on, I have OZC SLi Cert. 2GB of ram. I think its rated for 1066 Mhz.... what does that mean in real money? That I can take my FSB to 1800, have the RAM @ 912.5, and it will still be within limits? Sorry for all the questions! Thanks for the quick & detailed responses. Share this post Link to post Share on other sites More sharing options...
kingdingeling Posted March 17, 2008 Posted March 17, 2008 Yep, that's within the specs of the RAM Your sticks are rated for 1066, you'll be running them at 900 (450x2 = 900 DDR). Share this post Link to post Share on other sites More sharing options...
xPETEZx Posted March 17, 2008 Posted March 17, 2008 Right, tried some Overclocking tonight. First off went with a change of the FSB from 1333 to 1555, which at 1.39 volts (set in BIOS) This booted fine. I ran SuperPI, AquaMark 3 & 3Dm06. All passed and got better scores (14.xx s, 171xxx, 10,xxx scores) I then moved the FSB up to 1801, and suprise suprise no post. Then moved it down to 1777. Still no post. Moved voltage up to 1.40 and set FSB @ 1645. This booted fine. Also ran the 3 above benches fine. I then tried OCCT, which failed almost instnatly. I restarted and moved the voltage up. It kept failing till I hit voltage of 1.46 in Bios (Was @ about 1.40-1.43 under windowS) but it still kept failing. I was doing all this with Unlinked RAM. So I tried setting the RAM to Linked, and set the FSB to 1600 (this put the ram @ bout 1000) voltage as still at 1.46 This booted fine, but again OCCT crashed within 1 minute. I have reverted back to stock for now. Whats the next step? How do I get up to 4.0Ghz? Is it even possible with this board/CPU comob? Should I carry on upping the voltage/FSB till it passes OCCT? Should I OC using a Linked or Unlinked method? Thanks Guys!! Share this post Link to post Share on other sites More sharing options...
kingdingeling Posted March 17, 2008 Posted March 17, 2008 Northbridge and Southbridge voltages are your friend Share this post Link to post Share on other sites More sharing options...
xPETEZx Posted March 17, 2008 Posted March 17, 2008 How far should I take them? Currently my NB & SB is passively cooled? Should I get the Fan that came with the board out and use that? Or will it be ok without it? Thanks for the replies!!! Share this post Link to post Share on other sites More sharing options...
capthowdy575 Posted March 17, 2008 Posted March 17, 2008 yes the fan would be a good idea. anytime you add volts are speed up something we get whats called evil heat. the less evil heat you have the more you are able to push you parts sometime.

kingdingeling Posted March 17, 2008 Posted March 17, 2008 It all depends on the temperatures of the NB and SB, can you post those? I think you can see those with nTune (DO NOT USE IT FOR ANYTHING OTHER THAN TEMP MONITORING!!!111oneone!eleven) Share this post Link to post Share on other sites More sharing options...
xPETEZx Posted March 21, 2008 Posted March 21, 2008 Right done some more overclocking: Set the CPU voltage to 1.51 (droops to about 1.45 under load) Set SPP Voltage to 1.5 Set RAM voltage at 2.1 Set to Unlinked and set bus at 1601 Set RAM at bus 1001 Ran OCCT for 1 Hour and passed. Max temp was 66 C on both cores. Averaged around 63. Idel temp of 33. Ran 3D Mark 06 got 10,093 and ran SuperPI 1M and got 14.4 Seconds. Ran AquaMark 3 and got 176,000 What do you think?? I tried to take it to 3.7GHz and it was a no go. Failed OCCT after 1 Min 4 Seconds of OCCT. Any chance of getting this to 4.0Ghz?? I dont know what other settings to adjust other than increase Voltage more, but 66 C seems just about ok for me. Share this post Link to post Share on other sites More sharing options...
xPETEZx Posted March 23, 2008 Posted March 23, 2008 Been trying to OC some more, but cant seem to get anywhere Anywhere above 1610 is unstable and anywhere above 1650 wont boot. I dont really want to take the voltage any higher. It gets pretty hot under OCCT load (60-65 C) Any other tips for getting this to 3.8 - 4.0 Ghz? Thanks!

xPETEZx Posted March 25, 2008 Posted March 25, 2008 Anyone? Been trying some more, and cant seem to get more out of this chip I am not sure what other settings to tweak?? Even though my RAM is rated to run @ 1066, if I run it at 1066 it is unstable. Infact, anything above 1000 is unstable. However, no matter what I set the RAM at, I cant seem to get the FSB higher than 1610~ Thanks Share this post Link to post Share on other sites More sharing options...
xPETEZx Posted March 28, 2008 Posted March 28, 2008 :( Last night while playing CoD4 I started to get system lock ups. (System froze 3 times. Hard reset each time) So today I ran some more OCCT and it failed after 52 Mins with CPU too hot error. I then decided to seat the Cooler, and cleaned up the rest of the case, and it helped nothing. I have been trying to take the OC down abit, took the voltage down and then FSB, but nothing seemed to be stable. Back at stock now. I think either me, my chip or my motherboard are not cut out for this! Share this post Link to post Share on other sites More sharing options...
