FSB Overvoltage Control - Normal
(G)MCH Overvoltage Control - Normal
CPU Voltage Control - 1.3870V
Normal CPU Voltage - 1.3500V
Let's return FSB and (G)MCH to Normal voltages - I don't believe you'll need to overvolt there for a stable overclock at 3.2. And I suggest bumping the DDR2 up - this should put you in the range of 2.0-2.1v on your Ram. Now run your Orthos again for several hours. I will not be surprised if you are again stable. Please confirm that you are running Orthos version 0.41.110.18 - compatible with Core 2 Duo. Run the "Small FFTs - Stress CPU" test and confirm that you see two threads running, one on each core.
When you've confirmed stability, it will be time to try lowering your Ram timings to 4-4-4-12. Stay in touch.
Regards,
You and 5t3v0 were right in that I did not need the bump in voltage to the FSB and MCH. I dropped these both back to normal and re-ran rothos 0.41.110.18 and am still stable so this is good. I can now work on the timing of the memory. I did bump the memory volts to +.2 and speedfan reads it as 2.1 so there is an extra .1 volts floating around in there from what I set. This must be by design as every board in the forum does this. So when I reset the tighter timings I am planning on only bumping the memory volts to +.3 as this will more closely correspond to the rated 2.2 of these sticks and see if it will pass a couple rounds of memtest and then orthos overnight again.
I have one quick question in regards to the EIT and EIST concerning the lowering of the multiple and the volts of the CPU in idle states. I have them disabled for the purpose of finding my stable OC, but plan on using these once I do. I have gone into Vista's power option and followed the directions from the intel sheet that you linked to conjugal. However in vista there is no simple enable or disable the EIT technology, it asks that you specify a percentage as a minimum processor, I set this to %50. Should it be %0? Or is this alright?
thanks for all the help
@random - I am pleased that we've been of some help. I knew that you'd have very little trouble getting your rig stable. One simply needs to move one step a time, as you have done.
As to your ram - prevailing "wisdom" is that the MB "overvolts" DDR/VDimm by 0.07-0.1v. Mrfatboy, there, is trying to confirm this as we speak. Frankly and personally, I'm not willing to say that CPU-Z or Everest or Speedfan are necessarily accurate either, but that's the prevailing opinion. You say your ram is spec'd at 2.2v at the tighter timings of 4-4-4-12, yes? Then do the following: enter your Bios menu / press Cntl-F1 to get access to your voltages and memory timings / set your System Memory Multiplier to 2.00 / change your ram timings to 4-4-4-12 (leave everything else alone) / set DDR2/DDR3 overvoltage to +0.3v / hit ESC / save changes and reboot.
If you are running Memtest from a floppy, please ensure that you've set your Bios to look for the floppy first on boot. Then run Memtest for a couple of hours. I do not anticipate you having any trouble running Memtest error-free. After the test runs maybe 8-10 cycles, hit ESC, and your rig starts the reboot. Hit Delete as reboot begins, enter your Bios and specify your Hard Disk as First device to boot to. Boot to windows and begin your Orthos testing. Again, i don't anticipate any issues here either.
As to EIST and C1E - I'm an XP SP2 user. I can't help you very much re: Vista. Google the issue and I guarantee you'll get some hits.
