dling Posted January 19, 2010 Posted January 19, 2010 I cant seem to get to 4.0 gig on this proc. It's a DO stepping. I can run at 4 it just fails in occt with cpu errors. My current setting are 20x185 with turbo on. CoreV is 1.4. Heres a pic of temps after more than 30min. There fine. Any recommendations ?

Sup, Can you post your BIOS settings, such as : CPU Voltage CPU PLL Voltage QPI Voltage, this is VTT on your motherboard IOH Voltage IOH PCIE Voltage ICH Voltage ICH PCIE voltage DRAM Bus Voltage What type of error are you getting in OCCT, blue screens ?? error 101 means low Vcore, error 124 and 09c are low VTT ... if it freezes its usually low VTT Are you using Load Line Calibration, for CPU and QPI ??

dling Posted January 19, 2010 Posted January 19, 2010 Without VDroop CPU VCore - 1.4 CPU VTT - +300mV CPU PLL - Auto DIMM Voltage - 1.65V DIMM DQ Vref - +0mV QPI PLL VCore - 1.400V IOH VCore - 1.400V IOH/ICH I/O Voltage 1.650V ICH VCore - 1.250V PWM Frequency - 1067 KHz These are all my voltage settings.

Nicckko Posted January 20, 2010 Posted January 20, 2010 (edited) No suggestions? Your settings should be more than enough for 4.0 GHZ, have you tried different multipliers, such as 20x200, 21x190 or maybe 19*210, in my particular case the 19 multiplier seems to overclock better than 20 and 21. When I say better I mean that it requieres less voltage. Give it a shot. I ll post 4011 GHZ stable running on 19*211, with the following settings later on: CPU Voltage 1.25 CPU PLL Voltage 1.81 QPI Voltage 1.25 DRAM Bus Voltage 1.63 By the way, why is your Vcore in the screenshot under load of 0.9 Volts ??

I don't why the core V shows up like that. I do have it set to 1.4 I'm sure of that. Does the occt post your coreV correctly? I have tried 20x200 and 19x 200 but I get cpu erroes in occt :angry2: Is that a valid test? BTW 20x185 is really 21x185 because I have the turbo enabled.

Water_Hazard Posted January 20, 2010 Posted January 20, 2010 Try bumping up the VTT some more. try +375. Thats what it took for my 3520 to go from 4.0 to 4.2 Share this post Link to post Share on other sites More sharing options...
dling Posted January 20, 2010 Posted January 20, 2010 Try bumping up the VTT some more. try +375. Thats what it took for my 3520 to go from 4.0 to 4.2 Would I be able to lower my coreV after increasing the VTT or would it hinder my chances?

dling Posted January 20, 2010 Posted January 20, 2010 I was able to get to 21x188 with VTT at 3.75. What is considered excessive or to high? Share this post Link to post Share on other sites More sharing options...
RJR Posted January 20, 2010 Posted January 20, 2010 You may want to check you voltages with a multi-meter: 5v = 6.1v 12v = 10.47v That could be the best part of your problem right there, PSU. Share this post Link to post Share on other sites More sharing options...
dling Posted January 20, 2010 Posted January 20, 2010 I don't think that's a reliable reading. i know my coreV is 1.4 and it shows .93 Share this post Link to post Share on other sites More sharing options...
RJR Posted January 20, 2010 Posted January 20, 2010 It just seems that the D0's (most) are hitting 4.0 pretty easily now and it may be something else holding yours back. That's just why I suggested the multi to check and see. Hope you get it figured out. Share this post Link to post Share on other sites More sharing options...
