Shadowfactor Posted February 5, 2008 Posted February 5, 2008 So I got a E8400 today and installed if after a quick bios flash from DFI. about to get to overclocking, the only thing i have a concern for is the temperature's. I used AS5 b/w the cpu and waterblock. the bios is reading 28C for idle temps while coretemp is reading 45 C @ idle. Everything is fitted correctly and when I put the CPU into load only the top core moves to about 51 C while the 2nd core stays at 45 C My temperatures were never this high when I had my E6850, I wonder if my bios are giving the CPU more volts than it needs when set to idle. EDIT: Settings any ideas guys. I have a hump and I wanna get over it. Linked mode I have tried the following FSB: 1800 & 1850 Ram: 900 & 925 @ 5-5-5-15 LDT : 3X and 4X Ram V:2.3V Vcore : 1.45V NB : 1.57V SB core: 1.52V SB Dual: 1.62V HT: 1.42V HT VTT : 1.44 Idle ( Bios) : 31 C Idle ( coretemp) :45 C Load ( coretemp ) 59 C ( hottest core) I've played with Voltages FSB's ( checking for holes ) LDT Ram dividers I want over this hump bad.. dry.gif @ 4.05 Ghz I can get into windows but it will freeze upon any stress @ 4.1 ghz I can't get into windows. BSOD upon start-up currently sitting @ 3.9 ghz stable OCCT , Super PI 32 mb and Orthos 14 hours. Share this post Link to post Share on other sites More sharing options...
Shadowfactor Posted February 5, 2008 Posted February 5, 2008 Well currently i'm having a problem. It seems to me that my motherboard doesn't like to post when i push a FSB speed higher than 1500 mhz. I tried 1500 mhz FSB and it POST's fine but soon as i move up to 1550 mhz it doesn't want to post at all. settings: Linked mode 1550 mhz with ram @ Sync mode (775 mhz). Have also tried 1600 mhz linked with ram @ 800 mhz CPU VCORE : 1.4 V NB: 1.54 V SB:1.56V HT Voltage :1.32 HT VTT:1.34 Any idea's why the motherboard won't even post and CMOS has to be reset for any FSB's higher than 1500 mhz I used to run my E6850 @ 1600 mhz(3.6 ghz) with those voltages ( minus Vcore) and it worked great, Stable as a rock. I'm wondering if the 45 nm bios flash I got edited on my overclocking Share this post Link to post Share on other sites More sharing options...
hardnrg Posted February 5, 2008 Posted February 5, 2008 different BIOS releases have different FSB holes, and different values for stability... all part of the "fun" of the DFI 680i... I hope you didn't use CMOS reloaded to recall your settings, and hope you followed the BIOS flash procedure as detailed on the Tmod CD Share this post Link to post Share on other sites More sharing options...
Shadowfactor Posted February 5, 2008 Posted February 5, 2008 No i didn't use CMOS reloaded to recall settings and I used the Diamond Flash app thing through windows since I don't have a floppy drive. Should I try a higher FSB like 1650 mhz or 1700 mhz ??? Share this post Link to post Share on other sites More sharing options...
hardnrg Posted February 5, 2008 Posted February 5, 2008 do you do anything like load setup default, cmos reset, remove the battery when flashing the bios... or do you just flash from windows? flashing from windows is generally a bad idea... you don't need a floppy drive at all... I use a flash drive... you could use Tmods DFI Bios CD... you can easily get odd behaviour by not flashing properly, and it sounds like maybe you haven't Share this post Link to post Share on other sites More sharing options...
Shadowfactor Posted February 5, 2008 Posted February 5, 2008 There were a couple settings I needed to change in the bios like intl display PCI-E slot and I did reset CMOS before i flashed. I got it working.. there must be a FSB hole @ 1600 mhz Currently testing at 1700 mhz with 1.35 V with ram @ 850 mhz Running Orthos overnight..

hardnrg Posted February 5, 2008 Posted February 5, 2008 this is what you're supposed to do for the BIOS to behave correctly: Share this post Link to post Share on other sites More sharing options...
Shadowfactor Posted February 5, 2008 Posted February 5, 2008 well so far so good. 3.8 ghz @ 1.32 in the bios 9 hours Otrhos stable Share this post Link to post Share on other sites More sharing options...

philbrown23 Posted February 5, 2008 Posted February 5, 2008 dude mattwalter85 got his e8400 up to 4.2 stable but he's using an abit 2p35 pro not a dfi Share this post Link to post Share on other sites More sharing options...
road-runner Posted February 5, 2008 Posted February 5, 2008 dude mattwalter85 got his e8400 up to 4.2 stable but he's using an abit 2p35 pro not a dfi Well even though he may or may not want to go that high with his chip phil, I figured you would know by now that all chips are different....
