Hi all, well I have recently replaced my Q6600 B3 with a Q6600 G0. Now it seems that my motherboard (Gigabyte x38-DS5) is reporting the VID as 1.325v and the same in Core temp which is the same as my B3! This cannot be right can it? I am ideling at 2.4GHz with stock voltages at 21-25c in core temp, surely thats not my VID? Now on to the overclocking side of things, I can only get Windows to boot with my CPU at 3.3GHz on a 8x multiplier with 1.425v, anything below and it wont post. Mt temps when at 3.3GHz are currently 26 25 28 28 for all 4 cores. Is it just a bad vdroop? The core voltage in CPU-Z is 1.4v. Any help would be greatly appreciated, thanks.

Howdy! Interesting! VID stuff!
Did you re set your OC, place VCore on Auto with LLC disabled? FSB back to 266, speedstep disabled.
Try Core temp version 0.96.1. Just run prime when you get the VID and make sure it doesnt variate.
List your VCore voltage in windows at stock settings as well. You can guesstimate the VID from what it shows in windows.
To check your VDroop at whatever voltage, just open CPUz, note its idle value, then run small FTTs on prime 95 and note the new value after 3 mins. You can tell what yer VDroop is!

Load Line Calabration is a motherboard function designed to defeat VDroop. As you can see from your own test, your VDroop in windows is .032
That isnt all that bad. For an example. P5k-e Vdroop is less than .02
680i p5n32 e-sli .05 -.06
780i XFX starts at .06 and got to .08!
Maximus formula is +0.01! LOL, load line calibration works!!!
Dunno on my m32a whatever MVP for phenom.

Wait, 1.28 stock? Down to 1.248? Uhh, I would hate to tell you this, but your VID very well may be the worse possible one at 1.3250!! I mean, its not bad, but that explains your need for more voltage at 3.3!
You are getting the same effect I noticed when I compared my 1.2625 G0, and my 1.300 G0. Your's is just worse than my tests, because you have a processor thats tacked on a free .250 volt!
I hope I am wrong!

Humm, Lupi the thing is even at 3.35GHz with 1.45v the temps are as cool as heel and always stays between 24-28c idle! I just ran Orthos at 3.3 and 1.45v and it failed within 5 minutes. Man even my B3 was stable at 3.35GHz with that voltage, what is going on? Is it my RAM or Motherboard that is causing the problems? Thanks.

It very well could be, is your RAM on auto settings? Just let it post at spd settings, 800 5-5-5-15 @ 1.8 volt or whatever. I dont know what you have to reach the 3.3, x 9 multi or x 8? So I dont know what yer ram is runnin' at. Just keep it as close to 800/5-5-5-18 as ya can while OCing until ya get the processor stable.
Its okay to have cool idle temps, but that is a bit on the low side. No big deal if both core temp and HWmonitor report the same. Just be sure to have speedstep disabled in the bios.

No, for some reason my motherboard detects the Auto settings as 6-6-6-18 when the real stock timings are 4-4-4-15, I will try putting them to 5-5-5-18 now, thanks, if it isnt the RAM, could it just be a general motherboard problem? As I am very close to selling this one and getting an ASUS X48 Rampage formula, your thoughts? Thanks Lupi

Ok, well i left it on SPD settings with a 9x Multiplier with the RAM at 6-6-7-20 timings at 880MHz which is stable but 6-6-7-20 sucks lol, its very strange, my RAM is said to be default 4-4-4-15 but is 6-6-7-20!? Lol I dont know what to say, is my RAM faulty or something lol, well my hypothesis is that its either the Motherboard or the RAM causing the issue. Oh and even at 5-5-5-18 it wont post, ahh, thanks.

Humm, yea but not right now lol, hey Lupi or anyone else, I have managed to get my Q6600 stable at 3.4GHz with a 1.5035 voltage! LOL! The weird thing is, even with this crazy voltage, my temps are unusually LOW, i mean right now im ideling at 26-27c on all 4 cores with a 1.5v voltage. Do you think it could be possible that I actually have a really LOW VID, like 1.2v but my motherboard is messing it up and reporting the wrong VID? I mean surely these temps are too low to be at 1.5v right? Thanks.

Hi, thanks, I am using Core Temp and HW Monitor, which both report the same so I think its correct, room temps are quite cold and my case has its side off also, but the weird thing is evem if I try 1.6v at 3.6GHz, my PC refuses to post..Do you think it could be a motherboard problem rather than a CPU problem?

To test this, drop the multiplier to x 6, so assuming you're doing 400MHz fsb, you get 400MHz x 6 = 2.4GHz. This is stock speed, so run default vcore. Then you set the ram to the settings you want and increase the voltage of the NB and FSB appropriately, such as +.1V for both. After successfully booting into windows, run Prime95 or 2 instances of Orthos blend test for at least 12hours, 24hours recommended. Any failures would indicate either ram or motherboard, so tweak them around. After passing at least 12hours of blend test, raise the cpu multiplier to x 9 to get 3.6GHz and the vcore to 1.5V. Stress test using small FFTs for at least 8hours, 24hours recommended. Any failures would indicate cpu instabilities, so raise the vcore.

Man, I just ran Orthos then at 3.4GHz with 1.5125v on my CPU and my ram at 1:1 ratio with 2.00v and it stopped aat 4 minutes! Lol, what do you suggest? Thanks.A failure in small FFTs could mean unstable ram, motherboard, and/or cpu. I doubt it's the cpu, the voltage is more than enough. So it has to be ram or motherboard, which you'll have to spend some time figuring it out.
