jer3my Posted November 18, 2007 Share Posted November 18, 2007 Hi, Been trying to reach 3.2Ghz overclock but always failed after 1 hour of Blend torture test My Fsb : pcie = 1:1 at 100MHz FSB = 400 mem timings = 4-4-4-12 Vcore voltage = 1.35V Mem voltage = 2.2V Anybody using this motherboard? it's not the pro version Link to comment Share on other sites More sharing options...
DerekT Posted November 18, 2007 Share Posted November 18, 2007 What is the exact model of your DRAM? Please enter Here and set your entire system down for reference. Link to comment Share on other sites More sharing options...

DerekT Posted November 18, 2007 Share Posted November 18, 2007 Download memtest from http://www.memtest.org and extract the ISO image. Burn the ISO image to an CD-ROM disk. Please download CPU-z from Here and post screen shots of your CPU/Memory/SPD tabs after the overclock.. You can use http://www.photobucket.com to upload the graphics. Download Prime95 (OS: 9x/Me/NT/2k/XP) ---> Here Download Prime95 (OS: XP x64/2003 x64) ---> Here Download Core Temp Here Enter your BIOS Setup Utility and load default settings. Save default settings and reboot. Enter your BIOS and set: OC Guru CPU Operating Speed = User Define External Clock = 400Mhz Multiplier Factor = 8 DRAM Speed = 1:1 PCI-Express Clock = 100Mhz Voltages Control CPU Core Voltage = 1.4v DDR2 Voltage = 2.0v CPU VTT 1.2V Voltage = 1.27v MCH 1.25v Voltage = 1.33 ICH 1.05v Voltage = 1.10 ICHIO 1.5v Voltage = Auto NB Voltage = 1.4v DDR2 Reference Voltage = +2% CPU GTLREF 0&2 = 67% CPU GTLREF 1&3 = 67% Advanced Chipset Features Memory Timing Setting = <Press Enter> CAS Latency Time (tCL) = 4 RAS# to CAS# Delay (tRCD) = 4 RAS# Precharge (tRP) = 4 Precharge Delay (tRAS) = 12 Refresh Cycle Time (tRFC) = 35 Advanced Memory Settings Write Recovery Time (tWR) = Auto Write to Read Delay (tWTR) = Auto Act to Act Time (tRRD) = Auto Read to Precharge (tRTP) = Auto Command Per Clock: 2 Boot to the optical drive with the memtest disk and allow for two full passes. Run Prime95. Results? Link to comment Share on other sites More sharing options...
jer3my Posted November 18, 2007 Author Share Posted November 18, 2007 My Mobo is The Abit IP35 not the IP35 Pro Not all the settings can be applied. Link to comment Share on other sites More sharing options...
DerekT Posted November 18, 2007 Share Posted November 18, 2007 What settings are not there? Link to comment Share on other sites More sharing options...
jer3my Posted November 18, 2007 Author Share Posted November 18, 2007 CPU Core Voltage only in 0.2 increments. (either 1.39 or 1.41 Volts) No ICH 1.05v Voltage setting no ICHIO 1.5v Voltage setting no NB Voltage 1.4v setting no DDR2 Reference Voltage setting CPU GTLREF universal not separated can be set at 67% I guess for all 0&2 and 1&3 When I tried the CPU Core Voltage 1.39 DDR2 Voltage = 2.0 CPU VTT 1.2V Voltage = 1.275v (it only has 1.237 or 1.275) MCH 1.25 Voltage to 1.33V CPUT GTLREF = 67% with all the memory timings as advised, immediatly memtest 086+ booted with CD gives an error Link to comment Share on other sites More sharing options...
DerekT Posted November 18, 2007 Share Posted November 18, 2007 That is a moderate overclock and many changes should not be necessary. I have taken four E6750's to 3.6+ GHz. All were done on variations of ASUS including the low end ASUS P5B. One thing to try. Set you previous settings and change the PCI-e to 110Mhz. Test with Prime again.

jer3my Posted November 18, 2007 Author Share Posted November 18, 2007 Is it better to test stability with memtest then small fft in ortho or go for the blend test in ortho? cos when I tested with memtest it was fine for 6 rounds, then with orthos small ffts it was also good for 4 hours. but when I DID the blend test, it only runs for 14 minutes.

DerekT Posted November 19, 2007 Share Posted November 19, 2007 Stability with the DRAM in Memtest and small FFT's with Prime95. Orthos is buggy and the new Prime95 is better. Download Prime95 (OS: 9x/Me/NT/2k/XP) --->Here Link to comment Share on other sites More sharing options...
jer3my Posted November 19, 2007 Author Share Posted November 19, 2007 memtest fine for 10 cycles, and orthos small ffts good for 13 hours. Does that mean that i'm allright? Link to comment Share on other sites More sharing options...
DerekT Posted November 19, 2007 Share Posted November 19, 2007 Yes, you sound pretty stable. Link to comment Share on other sites More sharing options...
jer3my Posted November 19, 2007 Author Share Posted November 19, 2007 Thanks Derek for all your advices. Still failing blend test on Prime95 though after 10 mins. Dont understand why. cheers. Link to comment Share on other sites More sharing options...
DerekT Posted November 20, 2007 Share Posted November 20, 2007 This could be a program issue. Run your system 24/7. If you experience no instabilities or crashes, then I would not worry about it. Set your Vcore a bit higher and retest if it bothers you. Link to comment Share on other sites More sharing options...
jer3my Posted November 20, 2007 Author Share Posted November 20, 2007 No crashes whatsoever, everything seems to be fine. I reached my goal to overclock to 3.2Ghz with 4-4-4-12 mem timing and stock voltage. Pretty happy about it, not thinking of going further for a while. Thanks for all the help Derek! Cheers.

DerekT Posted November 20, 2007 Share Posted November 20, 2007 There's really not a lot of difference once you get up to those speeds. Most of it becomes theoretical since there is very little in normal use that will saturate 800Mhz at 4-4-4-12 and 3.2Ghz. Well done :) Link to comment Share on other sites More sharing options...
Tierce Posted November 28, 2007 Share Posted November 28, 2007 Hey jeremy, I also have an E6750 that I currently have OC'd at 3.4 GHz. Sidetrack - Derek, I'd love to see some of your BIOS settings for the systems you have OC'd with this chip as I want to get mine up to 3.6 GHz as well. PM would be great. Ok, back to the topic, I also ran into problems with Blend tests using Prime95 and have come to the conclusion that the program is buggy. I was able to run Small FFTs for many hours with no errors, same with Memtest. Sometimes Prime95 would not actually find an error, the program itself would just crash and prompt me to send an error report to microsoft. I have had similar problems with Prime95 Large FFT tests. I have Orthos, but have never used it. As Derek said, getting to 3.2 GHz with that chip should not require you to change very much. If it is GO stepping like mine, you will more than likely not have to adjust the CPU voltage at all. Using my setup, I did not have to start adjusting the voltate until I raised it up to 3.3 GHz, and that was only a minor increase. I had everything set to default settings when I clocked up to 3.2 GHz and was able to run Small FFTs and Memtest for several hours with no errors.

The last one I clocked up was an E6750 (btw, all 6x50's are G0 Steppings) and I didn't have to do much other than raise some voltages and set to 450 X 8. I used 8500C5's with it. The Board was a P5K-E/Wifi (only because I can't find the non wifi's around. I set to ~1.5V in the BIOS, termination voltage was ~1.45v. North Bridge was ~1.4. There was not much else needed as the P35 chipset really doesn't need a lot of tweaking. I have worked with more E6850's though. Cooling was a Tuniq Tower.
