Awesome

My Q6600



Either my mobo or PSU are 2 weak for Prime 95 .

[speedfreak86]

VID?

1.2250 is the VID

@Gir92

What are the rest of your voltages set at? Nice clocks.

That chip isn't long for this world... What kind of cooling and what temps are you getting out of curiosity?

4.2 finially stable on a cool 1.76v

[The Water Dog]

My batch is SLACR L7298B098
Is it other here that have the same as me?
Have a good weekend overclokers=)

[dnottis]

What PSU for that? I'm extremely jealous...

Sorry havent been here in a bit...

Cooler Master UCP 1100 Watt

@Gir92

NB on my P5Q-E is at 1.36v, PLL at 1.7, VTT at 1.58. Left GTL stock.

The 65nm Intel chips are tougher than you think. People have ran their chips at 1.7v for 2 years without a problem.

I'm on water. Idle in the high 20s to low 30s and load in the 50s. Ambient of ~15-18C

[xdrift0rx]

well im not sure if this counts because i had to go into safe mode cause everytime in vista after it would initiate my USB devices, it would blue screen. so...here it is.

1.56v according to bios

[fatguy1992]

WTF its got like no info not even fsb and multiplier.

Edit: Wait got it now, it failed to be validated.

[=[PULSAR]=]

Heres a recent shot of mine looks to have good VID but its a pain in the butt trying to get it stable above 3.7ghz. Anyone have any ideas maybe its a setting in my BIOS that I'm forgetting?

[Loser777]

Same thing here... can't go much higher than 3.6GHz, but I'm pretty sure it's my PSU. What are your settings right now?

[Sailindawg]

That's pretty good clocks for 1.33 Vcore, if I'm reading your screenshots correctly. Raise your Vcore. Mine will do 4.0, but, it needs to some serious volts to do so, ~1.63 Vcore with Vdroop correction enabled. You will need to raise Vcore, VTT and NB voltage to go higher. Adjust GTL's as necessary. ~1.5 Vtt should be good for 24/7. Since your cooling with water, your temps shouldn't go much above mid 60's under full load at higher voltage. My chip doesn't get much over mid to high 60's at 1.63 V Vcore under P-95.

[=[PULSAR]=]

I'll give somethings a shot what are the ranges for GTL on Q6600?

[xdrift0rx]

for my dfi 680i i use 145, 95, 95. with 1.44vtt

also my cpu z was validated because when i tried 4050mhz it didnt allow it.
as i said, i was running in safe mode which is why you cant see the multiplier, fsb etc.

[=[PULSAR]=]

yea looks like the GTL voltages were the culprits. Have them set and have been stressing for the past 30 minutes where as before it would fail at first iteration. 3.8ghz stable @ 1.52V pretty good? Also does the VTT really matter as long as it correlates with the GTL?

[fatguy1992]

Does anyone know what the WR is for highest FSB on a Q6600?

[=[PULSAR]=]

What are mainly is everyone running for NB voltage for 420-430FSB range?

[dan7777]

my q6600 siting at 3.8 1.58vcore ides 36/load/69

[fatguy1992]

What are mainly is everyone running for NB voltage for 420-430FSB range?

Depends what motherboard. My P5E needed 1.5v or so, but my UD3P needs under 1.4v.

[rockfella]

My Ip35-E needs 1.33 MCh for 425 X 8 = 3.4 ghz stable OC.

[Sailindawg]

@=[PULSAR]=

Also does the VTT really matter as long as it correlates with the GTL?

Well, as long as you don't go much over 1.5 V and keep GTL's to 0.667xVTT, you should be fine. What I usually do is multiply my desired VTT voltage by 0.667 to get my corresponding GTL voltage. There's a look-up table for the BlackOps that corresponds the BIOS settings for the desired GTL voltage for the corresponding VTT voltage. I will resort to adjusting GTL's only when one core is failing and the other three are passing. I have done the same with northbridge voltage and northbridge GTL tuning. I have also used GTL's to lower Vcore, once I have found stability at a certain Vcore. GTL's are for fine tuning.

What are mainly is everyone running for NB voltage for 420-430FSB range?

It depends on your board, chipset and how much RAM you are using, 2x1G, 2x2G or 4x1G. It also depends on whether your dimms are single sided or double sided. Single sided dimms are easier to run than double sided.

On my board, with 2x1G DDR3, I use about 1.5V NB for a stable 8x450. For 9x412, I can use 1.46 V NB for both 2x1G RAM and 2x2G RAM. The cooler you can keep the NB, the better off you are in terms of stability.

Hi guys. I'm going to make my first overclock and i need some help. I have a Q6600 vid 1.2125, is it good? I want to put it on 3'6, what changes the number of the multiplier? it's 400x9 acceptable? I guess i will have to turn up the voltage to be stable, no? I am on air (Noctua NHU12P) and G.Skill 4gb 800mhz on xp32

Sry for my n00b questions and my poor english :$

Cheers

[Khalmyr]

yes. 1.2125 is actually the best VID i've seen in real life.
i've heard of 1.2000 but they all turned out to be reading bugs =P
