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.
Update: 3.3GHz isnt stable on 3DMark with the above settings! aghh whats wrong with my computer? I don't think it's the CPU as the temps are very low. I am starting to think its the RAM or motherboard. Please any help would be greatly appreciated. Thanks.
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!
Humm, do you mean reset before taking out my old B3? Cause I don't think I did lol. Humm whats LLC? Man I hope I don't have a broken/faulty motherboard, My Voltage in CPU-Z is 1.28v. I will do what you said with the VDroop now, many thansk Lupi! I knew you would help mate.
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!
Humm, very interesting, what do you suggest I do? Even with 1.475v at 3.4GHz it is unstable. But the weird thing is my temps stay below 28c at idle, so where should I go next? Thanks.
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.
You have to manually enter in values that go beyond the 1.8 volt.
They do that so it boots in most MoBos. If you want a board, get a p5k-e wifi, 150 bucks and HUGE FSB possibilities!!
I need to catch you here and see ya on an instant messanger of some sort, posting sux!
Ahh, cool that may be a possibility, although im thinking of the ASUS Maximus formula, ok I think instant messaging would be cool, whats your MSN? Thanks.
Any help will be grateful, thankyou.
