The E0 Q9550 SLB9V thread (finally!)

[MacClipper]

1.15V

Nice, even < than my E0 which is 1.1/1.1625v, your clocks show that there are really good C1s out there too.

Thanks. There's another lucky chap on another forum with a similiar C1 achieving 4GHz at 1.3v ish. Only thanks to his results I tried it out as I thought I'd never be able to hit 4GHz with it

[carepolice]

I could do 24/7 3.8Ghz easily, but meh 3.6Ghz and 3.8Ghz cant see any difference

One thing that keeps me is my VID, it should be "THE" stock voltage on load?!

But still i get this


1.16 on load!



And my real VID is a 1.2500 according real temp!

The 4GHz brings my input power (W) down because my PSU is at the power curve where it's most efficient

I've still got to do some measuring of that too. Plus it'll keep me warm a bit through winter

Yeap, in week always when i get home from work my rooms temperature is +21c and then when i am going to sleep its on 26c

1.16 seems even stable

I can't boot at 0.9v though :p

[carepolice]

haha 0.9 would be great

[vox]

C1's aren't bad.



Still priming. I know it'll be stable as it ran IBT all night and passed, it gave me higher temp readings too. When going to prime it failed within 12 mins, twice. So I've upped the VCore and it's still stable coming up to 1 hour
Ram is being gay though

Hello moogle!

I cant get stable ate 483 x 8.5 i have

vcore 1.4
gtl 0 auto
gtl 2 auto
vpll 1.575
Vtt 1.44
vdram 2.0
vnb 1.38
gtl nb auto

can you help me with your specs for the gtls? tks

vox

[moogle]

My settings are:

VCore: 1.28v
VPll: 1.5v
VNB: 1.2v
VTT: 1.2v
VDram: 1.9v

CPU GTL: +40mV (I'm on Maximus Formula II so I don't know how you'd convert that for your board)
All the other GTL's are auto.

Hope it helps.

Really guys every chip is different, every build is different!
Copying bios settings wont help on your own situation!

As my Q9550 whit MASSIVE 1.2500 VID runs 3.6Ghz (my 24/7)

vCPU: 1.28
vFSB: 1.14
vNB: 1.14
vDimm: 1.82
vPLL: 1.52
vSB: 1.1
vSATA: 1.5

I know but someone asked for some help

[pascalbrown]

Can someone who is prime stable with an fsb of 480 or more please post their bios settings. The general ones plus gtl ref and any clock skews etc. It would be a great help! Thanks.

[mngdew]

My latest. Installed it just 2 days ago.

I thought...
vid is the lowest voltage that a cpu will run at stock or at least what intel says it is

am i wrong?

or this>?

The VID is part of the uCode that the chip is imprinted with when it leaves the factory. Each chip's VID is different based on its results with Intel's testing processes. What the VID is supposed to do is tell the motherboard, "Hey, this is the voltage I require when the FSB is set to default and the voltage setting is 'Auto'." It varies from chip to chip, as each chip has different tolerances and requirements based on the fabrication process not being 100% perfect.

Sounds kinda true...

But... On my situation auto on stock is 1.16 on load, still all programs says that VID is 1.25

On this C1 Stone i can run stable at 1.25 max 3.5Ghz, 3.6Ghz needs 1.27

[5010]

1.16 is the Vdrooped reading... 1.25 VID is THE BIOS related voltage setting taking into account VDROOP which is part of intel's CPU spec.

[WC Annihilus]

Here's mine. Batch is L830B421, VID of 1.2375.

Lowest volts at stock speed, 1.040v idle, 1.008v load:



What I'm running now, 4.05GHz, 1.304v idle, 1.248v load



Very happy with this chip. I managed to boot into Windows at 4.25GHz with 1.392v, but cause of the terrible vdroop of my board, it froze when I started prime as the volts dropped down to 1.336v.

[5010]

Pickin up an E0 Q9550 of unknown batch in about an hour Can't wait!

...She's here! Batch: L827B201

Transplant time..

[5010]

The Thread title says "The E0 Q9550 SLB9V thread (finally!)"

But my E0 Q9550 says "SLB8V"

??

[MacClipper]

But my E0 Q9550 says "SLB8V"

??

Ah, SLB8V was last year's model, sorry but you bought the wrong chip.... j/k.

It's clearly a typo, was hoping some mod would have corrected it by now.

[h1ms3lf]

don't wary man! mine does 4k MHz with 1.287 and 500fsb

[GAR]

mine does 4ghz with 1.4v lol, vid is 1.2 i got a bad ship prolly. I dont plan on keeping this for more than 8 months anyway.

Well not the best one

[5010]

You think yours is bad? Ha!

Mine has a VID of 1.25

If that's not bad enough I'm on a EVGA 790i Ultra running her @ 3.775GHz, If I go any higher I get BSOD's all over the place "A Clock interrupt was not received on a secondary processor within the allocated time interval"

That secondary processor is my Video card(s) since sometimes if I have the GTL's just about right the screen will flash black and windows tells me that the video driver recovered from a serious error. if I run my current 8x444 at any higher than 1.25VTT there's no combination of GTL's I can use to stop this and believe me I've tried to nail them down. If I run my FSB any more than 444x8.5 there's no combination of VTT/GTL's AT ALL that will keep her running...

3.775GHz is 20x Linpack stable.

I overclock every single day, it's part of my job(at a boutique) but I've never met a CPU *cough* B*tch *Cough* like this one.

Very low leakage chip since with 1.36V @ 3.775 it barely breaks 60C on air..... Damn where's that emoticon ::smashing my face against a wall::

Anyone have any ideas?

Update your Mobo BIOS!


Hi,

temporally I own an Q9550 E0 with 1,1875 VID. 1,408V at 4165MHz!
http://www.abload.de/image.php?img=piq46di8.jpg

I ordered another one with a completely new Batch. L835A has anybody ever heard of it?
