kozary Posted June 6, 2009 Posted June 6, 2009 (edited) my rig specs: Mobo: ASUS P5Q SE/R P45 chipset RAM: Transcend 2gb, 667mhz valueRAM at its best CPU: C2D E7300 2.66ghz gfx: GTX285 but using a 6600 with 400watt psu CPU cooling: Zalman 9700LED 400watt PSU will be getting back my 1000watt from RMA very good case ventilation no heat gatherings anywhere standard CPU voltage- 1.144v under load Well the problem is that i cant get 4ghz stable, plus i noticed that i am using a higher voltage then all the other dudes who have E7200-7300s to stabilize the same frequencys I read that someone had his E7200 stable @ 3.6ghz without bumping the voltage up and ive seen 4ghz pulled off with 1.37volts. i have to increase voltage to get 3.1ghz stable....... With my current overclock i get 3.6ghz stable with 1.336volts (1.35 in BIOS) and i cant get 4ghz stable at all but bumping the voltages did help i stoped at 1.44v (1.45 in BIOS) since i thought it was pointless to keep increasing voltages without properly considering it. i got 3.8ghz fairly stable with 1.4v in BIOS. But i think this CPU should have it in it to get 4ghz without those voltages The things that i looked into already: VDroop - i have allready taken care of this with load line calibration voltage increases under load Vtt (FSB termination voltage)- i tried 1.1 thru to 1.4, no luck there NB volts - tried 1.1 and 1.3 and 1.4 still no luck SB volt - increasing this just made it more unstable RAM- it is pretty likely my 667mhz ram is a hold back it runs @ 800mhz with 4ghz, i have ran it upto 889mhz stable enough to benchmark mb- maybe this mobo is to low to OC well heat- reaches 47 in Prime95 with 3.6ghz. NB and CPU skews- i messed around with this a little didnt really do anything degradation- i noticed that after going to 3.4ghz and ran intel burn test with a stock heatsink which was very damn stupid i noticed i had to bump voltages to maintain overclocks that i had already deemed stable. Also when i first got this thing i got to 3.4ghz with no voltage bumps and ran crysis and . fine. Maybe i left the TM function off and damaged my CPU? crappy chip- i heard that some people get chips that just wont overclock very far. =\ PSU- due to this PSU's age it may not be giving the best supply of power causing instabilities somewhere The things i have left it the RAM, PSU and Clock skews and the GTL Reference voltage which i did play with a little and it didn't really help me. All suggestions and help is very highly appreciated P.S i did use my mates Kingston 4gb 1066mhz in my PC once, i bloody forgot to try overclocking =[ edit: i probs should have posted this in the overclocking section...lol Edited June 6, 2009 by kozary Quote Share this post Link to post Share on other sites More sharing options...
