Q9650 voltage help .

[trickson]

OK All you TPU Geeks I need your collective brains to come up with voltage settings for me here is the list of voltages I need your help with , Get me stable at 4.2GHZ People I am almost there but I need your help . Look at he picture below and tell me just what to set every thing there to PLEASE I want to get to 4.2Ghz and have it stabler than it has been . I think it is all about the voltage rith now as every thing in the BIOS is on AUTO for now .

Thank You all so much !!

1.25v on a s775 quad core? That can go up for sure. Start there.

Yeah it is low but I am at 4.0GHz right now with that setting !

 

[erocker]

Well then it needs moar for 4.2ghz. With your elaborate cooling setup start at 1.35v-ish and go from there.

Ok what about CPU PLL , GTL and NB/SB voltage should I up them some too ?

 

[trickson]

Ok got it set to 1.4 Volts in the bios , I can get 4.2GHz no problem but it is still a tad unstable . so what should I try next ?

 

[EastCoasthandle]

Try loadline calibration. But disable all speedstepping or C1E support though. You don't want any voltage fluctuation with LLC enabled. But you will need to back down on your current voltage IMO.

DID this from jump bro . What should CPU PLL and GTL and NB/SB voltage be ?

 

[EastCoasthandle]

NB shouldn't be that much (1.35V or less). You shouldn't have to mess with SB IMO. Hmm you are already at 1.80V. IMO (unless there is something we are missing) the chip is a no go for 4.2GHz for 24/7 use. IMO, you should start over but this time start with just the CPU voltage then work you way to the other voltage tweaks. IMO, your CPU voltage is way to low and you are trying to compensate with the other voltages.

Thing is in the bios all the settings are at auto right now except for the CPU voltage that is set to 1.4v . How high can I safely go on the CPU would 1.45v be ok ?
As I see this the CPU PLL is very high 1.8v it is on auto in the bios .

 

[EastCoasthandle]

I see, I wasn't sure what you had it set at other then what you posted in the OP. 1.400Vcore is a tad to high for that CPU. Max is 1.4500Vcore (I believe) but I wouldn't use that for 24/7 use. What that means is that the CPU can auto clock up to 1.4500V and tapper down (vcore set to auto). It seems to me you hit the wall.

Ok that is what I was thinking as well . I just thought there might be some voltages that would help get total and full 24/7 stability at 4.2GHz is all .

 

[EastCoasthandle]

Heads up, max VID is 1.3625V

 

[trickson]

HMM Interesting . Thanks for the tip . I have it set to 1.4v but it isn't going over 1.35v for some reason maybe because of that ? CPU-Z says 1.33v .

 

[EastCoasthandle]

That's vdroop as far as I know. LLC would fix that unless there is something else going on. But you are (from my point of view) on the high side of the voltage scale.

yeah there is the vdrop going on and inline calibration is enabled too .

 

[EastCoasthandle]

IMHO you need to clock the frequency and voltage down a bit if that's happening. try 3.60 or 3.80.

well 4GHz is perfectly stable 24/7 not one glitch ever . just when I hit 4.2GHz that is when it becomes unstable .

I'm running my q9650 at 4ghz has been that way for a year 100% stable! It runs quite fast using the h50 cooler, just wanted to say don't go over 1.3625 as somone else said that's intels max recommended voltage? And when I was setting uP mine I read about ppl frying there chip at 1.4 volts anyways good luck mate!

Edit; btw I am running under 1.3625 to get a stable 4ghz

I had have had my q9650 to 4.5Ghz. You need to look at your RAM Divider.

It could be you are pushing your ram to far.

My media PC has the q9650 now. Running 4.1Ghz (1.4v) with ram at 9xxMhz.

You running DDR2. I bet it is your ram. I had serious stability issues with my RAM above 1100Mhz and the CPU above 4.2Ghz. Clock down your ram and see what happens.

I was able to hit stable. 500FSB, 4.5Ghz, 1000Mhz Mem.

geez. 1.4v is too high for a Q9650. 1.45 is too much. As your pll. Loosen you rams first. Always start with loose rams.


Here is mine, I have no OCCT xx hours with it, havent have the time. Just did IBT, but I can still play BFBC2 without crashing or do benchies with it.

Rams are still @ 1:1 cas 5 (you can tune that later). Spread spectrum and all that extra cpu instruction trash is disabled in bios.

1.31v cpu core, 1.4v nb, 1.56v pll, LoadLine calib, the rest is auto.. what application do you use to see the voltages in win7 x64? We have the same board, I can give you the voltages and stuff. If it still wont cut, then its a proc thing

And yes, thats 80c on full load lol. its a cozy 32c ambient in this room. My rad is internal so its basking at a 34c degree ambient XD

 

[cyriene]

I have a Q9650 running 4.2GHz rock solid for a couple years. Totally forget the settings though; maybe later today I'll be able to check on that for you.

 

[Animalpak]

mine is 1.28V 3800 mhz for many years now, absolutley no issues.

 

[overclocking101]

he is running TEC cooling so theoretically 1.4v should be fine depending on the temps he is getting. usually on 775 board it was the ram that held back. if you run high NB voltas you will get better ram clocks. also your GTL's directly impact performance. messing around with those can help gain a couple extra mhz. also PLL voltage is the voltage supplied to the CPU clock generator 1.8v is stock for most and is fine usually up to 4/4.2ghz, for higher clocks try 1.9v PLL or 1.7v even (some boards lowere is better)on my P45's (maximus 2, DFI, P5q-e) in order to get higher fsb OC's (450+) I need 1.4V NB AT LEAST. the better the cooling the better the oc will be aircooled I wouldnt g over 1.36v water/TEC 1.4/1.425v is fine DICE 1.55/1.6 LN2 1.6+

 

[grassy]

Been running this for a year with everything in the bios on auto apart from the cpu voltage... should i set the other voltagers or leave them?
