troy5061 Posted March 10, 2008 Posted March 10, 2008 (edited) I tried the above suggestion and i get to windows but it locks as soon as i get in. I now have modified my settings at 3.6 to the above settings and my v core is at 1.3v cpuz reads 1.2 and it seems to be stable Cpu Vtt voltage what should this be at? its the only auto I have left. even tried 1.4 vcore nb 1.5 sb 1.5 ht link 1.4 memory 2.1 unlinked @ 800 and it did the same thing. Im making some headway 1.35v core 1.45nb 1.5sb ht link 1.4 memory linked at 844 3.8 ghz Edited March 11, 2008 by troy5061 Share this post Link to post Share on other sites More sharing options...
Shadowfactor Posted March 11, 2008 Posted March 11, 2008 (edited) As far as CPU VTT Voltage. My E8400 likes Voltages slightly higher than the HT link voltage. But this setting really depends on the CPU. I wouldn't go over 1.45V with it though... Those seem to be good voltages for a start. The SB Voltage is fine, but your going to have to pump up the NB volts more if you want to go any where close to 4.0+ ghz.. What are your temps like now with those Voltages.... NB , SB temps. I can see the CPU temps Try backing the CPU Vcore to like 1.25V or something and see if you can be stable at 3.6 ghz... I can get 3.6 ghz on stock Voltages. The E8400's seem to be really picky above the Voltage you run them at. Most people think the more voltage the better the stability, but I noticed with my E8400, if I give it to many volts it'll actually be less stable than if it was undervolted....

Asus Pc probe says my mobo temp is 36C That is at 3.8ghz 1.35 v core 1.45NB 1.5SB 1.35 HTT Ill set the VTT at 1.4 What do think for a starting point for NB voltage to get 4.0 Share this post Link to post Share on other sites More sharing options...
Shadowfactor Posted March 11, 2008 Posted March 11, 2008 I'd say 1.5-1.6V depending how much Vdroop your board gives.... 680i's are Volt-hungry when trying to get over FSB's of 400 + Share this post Link to post Share on other sites More sharing options...
troy5061 Posted March 11, 2008 Posted March 11, 2008 (edited) I'd say 1.5-1.6V depending how much Vdroop your board gives.... 680i's are Volt-hungry when trying to get over FSB's of 400 + No luck....it really doesnt want to give up that extra 200mhz. I tried 1.35-1.4 vcore 1.5sb 1.5,1.55,1.6nb vtt 1.4 ht link 1.35,1.4 no luck it either wont post or will freeze loading windows. I think its something with my ram because even at 3.6 or 3.8 running the ram over 850 causes it to either not post or crash. Its now at 3.8ghz 1.3vcore 1.2 in cpuz nb 1.45 sb 1.5 ht link 1.35 vtt 1.4 I really appreciate all your help with this Im still shooting for 4.0 but 3.8 is very good and I can live with it as it looks like I may have to lol and 200mhz is probly not worth pushing the board that hard. You were definetly right about the cpu voltage 1.3 and its running good, Im going to dual orthos it tonight. Should I go any lower???

troy5061 Posted March 11, 2008 Posted March 11, 2008 seems to be pretty stable at 3.8 Share this post Link to post Share on other sites More sharing options...
Shadowfactor Posted March 11, 2008 Posted March 11, 2008 well for 4.0 ghz you prolly need to bump the Vcore up to like 1.375-1.4V in the bios. The Vcore I gave you was just a starting point, you can move any of the Voltages. Move them one at a Time and see how it affects your stability.

troy5061 Posted March 11, 2008 Posted March 11, 2008 I tried 1.4vcore 1.5, 1.55, 1.6 nb 1.5sb 1.35, 1.4 htt 1.4vtt and it didnt like it.....why wont my ram overclock very high...ie over 860mhz Share this post Link to post Share on other sites More sharing options...
Shadowfactor Posted March 11, 2008 Posted March 11, 2008 Well try 5-5-5-15 on the ram @ 2.1 V or whatever your ram says. It could be the Ram Divider that you have. Try a slightly different FSB speed. You might have hit a FSB Hole. Share this post Link to post Share on other sites More sharing options...
troy5061 Posted March 12, 2008 Posted March 12, 2008 Im going to keep trying. Thanks for all the help. Its going to be a trial and error process that will take some time, but I saved my oc profile the way it is as a good starting point.

troy5061 Posted March 13, 2008 Posted March 13, 2008 I think theres a fsb hole, I can get 4.2ghz but it fails orthos after 2 seconds. I tried with these settings. 1.3375vcore 1.5nb 1.6sb 1.35htt 1.4vtt any higher on the nb and it wouldnt boot into windows and any lower on the sb and it would freeze up....maybe I need some more cooling on the nb and sb Share this post Link to post Share on other sites More sharing options...
