The E0 Q9550 SLB9V thread (finally!)

[unclewebb]

These CPUs have a Minimum and Maximum VID. Take a screen shot of Core Temp while Prime95 or similar is running so your CPU is loaded.

That might be your maximum VID but it looks more like your minimum. Your multiplier is at 6.0 so it's likely your Minimum VID in that screen shot.

Ok, this screenshot was taken while Cyberlink's MediaShow Espresso was transcoding some blu-ray video from my sony hd cam to 720p wmv. This seemed to load up the cores pretty good. Looks like vid is 1.2v.

x8.5


the same VID.

[MrDucky]

his VID is the max VID man , get over it, (coretemp 0.99.5 reports fine my VID , in "idle" mode, wonder why would not reporting his...

@fdisker : nice VID , hope clocks really well

So you say my vid is 1.00V?

[papatsonis]

no im saying that..

and that..


the above is the proof for the 2nd part of my quote.(Unrealer also showed that)

as for the 1st part, im full of guys who are uber skeptical, when see something too good to be true to... their standards.. (like were ppl on my VID initially) , that's why for a L847C seemed "common" a 1.1v "area" vid and it had really good chances to be the "high" VID (as fdisker showed unfortunatelly it was the LOW VID of course :/) , that's why my reaction..

[unclewebb]

A lot of this depends on how your motherboard is set up and also how Windows has been set up and what energy saving features you're using. Sometimes when the multi drops down to 6.0 at idle, the VID will also drop down. On other motherboards, the multiplier will drop down but the VID will remain high. That's why when reporting VID, it's best to have a load on your CPU to try to get around this.

Here's a few examples of what the latest version of RealTemp shows.
My E8400 will drop the VID down if I'm using the default multiplier but if I go into the bios and lock the multi to 8X, then in the same situation VID never drops down.



At full load, both Core Temp and RealTemp report the same maximum VID.
In the RealTemp settings window, the Maximum VID is always shown.



Now here's the fun part. If you know what you're doing you can go in and manipulate a register within these CPUs and force the CPU to report the wrong VID.
All software will fall for this trick because the CPU itself is reporting the wrong information. Watch out for uber VID chips on EBay.



At full load, this E8400 is being forced to report the Minimum VID of 1.150 even though the Maximum VID is actually 1.2250.
At least the RealTemp Settings window is smart enough to spot this kind of fraud.

Whats the max vcore for WC?

[overclocking101]

hi i have this chip and a black opps. its vid is 1.3V max but runs stock on 1.19V im haveing MAJOR problems getting above 3.7GHZ could someone help? maybe its a black opps issue and thers no real telling as foxconn has completely abandoned quantum force wish i knew that was gonna happen when I bought the black opps. woulda went ASUS if I had known

[fdisker]

Thanks for the clarification on the min and max VIDs. I'm not an extreme overclocker by any measure and I didn't want anyone to think I was trying to fool someone into thinking I had some super fabulous processor. I was just trying to add to the dataset of the thread. My chip won't see anything north of 3.2ghz.

[Hardc0r3]

anyone selling a good q9550 or q9650 ? Is there a forum section, buy , sell stuff? , i need a Q9X50 E0 which will do 4ghz @ most 1.28v

I also have a q9550 L847c...(forgot the last 3 numbers) running at 4gh (8.5x471). I got the vcore down to 1.296v (report in cpu-z, 1.3250 in BIOS) with 1.34 on the NB. Maybe you should try the same ? You go from 1.296v@3910 to 1.352v@4003.
Just a tought , congrats btw

You could spend your BIOS settings you are using to 4.0GHz? Here I have done several combinations of values, but I will try to 1.34V (VNB) here. Thank you.

[phsinc1]

can someone post everest cpu cach benchmark @ 4250Mhz (500x8.5)?

hi.insane 11 what are your volts for that 500x8.5 as ive got mine so far with v-core at 1.33 (1.3625 in bios) and need to have fsb at 1.46 with northbridge at 1.32.and for 490x8.5

[caRpetbomBer]

Not bad at all

[doodle]

oh didnt realise your using DFI board as ime using ASUS P5Q-E .still nice overclock though.

[Hardc0r3]

here is my 24/7

[MrDucky]

insane how do you keep your northbridge so cool mines always above 40C even with just 1.15v ...

i use thermalright HR-05 IFX on my dfi dk p45 board..

[Gaul]

ON progress........HIGH VID , LOW TEMP !!!!

4 GH @ v1.25




TRY VANTAGE

[Unrealer]

Im thinking of change the mobo cause i tried 6 Q9550 E0 and I got almost the same results with all, so, will be the DFI LP P45 Dark much better than the LP P35 Dark? for example, i need around 1.5v @ NB to get 4Ghz stable


This is the last Q9550 i tested:
