The E0 Q9550 SLB9V thread (finally!)

[seban]

today my rock solid

If it was only as on screen 1h20m p95 stable than I would say it is nowhere near rock solid.

Maybe he has already burned it whit intelburner
Well he didnt mention it so who knows

[riokabuto]

Nice clock! but does that really need 1.40V on vNB/vFSB ?

i'm trying


but now i have 1,3

i'll try to set 1,2 later

[Hoss331]

what have i to change in the bios to arrive at 500 fsb ???


thanks !

Are you wanting a stable 500 or just a bootable superpi 500? For 487 I use 1.3875vc, .655gtls, 1.58, 1.4, 1.38, .665nbgtl, this gets me 8+ hours prime blend. For 471 I use 1.30vvt and 1.32nb.

how much test time for the RS - intelburn ???

i'm downloading it !

[carepolice]

10 test for max memory (1 - Maximum Stress)
20 test for half of memory

then this is no good for you ?

[seban]

M8 I am not sure if it is to me or not but I will answer as I am bored ATM.

So it really does not matter if it is good for us or not, what matters is it good for you? And in fact what really matters is if it is good for your system.

And answer for last of my previous questions is - No M8, I am sorry but 10 passes of IBT says nothing without around 12h of p95 Blend. When you reach 12h of blend and 10 Passes of full stress IBT then you might be stable. If you care about being stable you should follow this road (but even after 12 prime and 10 IBT you can still be not stable).

Have fun

problems...

with level 1 i receive always an error...
with all system on default too...

with level 2 no problem...


i have to disable the PAE ( i have 4 gb ram ) ????

I would help you but I do not know your MB also you did not post your template. Anyway the best place to look for answers is thread of your Mobo. Look for one here on XS and probably there will be ppl able and willing to assist you with your problems.

+1000Mhz out of the box (vcore lower than vid :-) )


+ validation

[xguntherc]

wow.. thats very good. and no the vcore isn't lower than the VId.. thats just the vdroop that always happens. it's probably set to 1.2500 in the BIOS. but nice work either way.

anyways I had a question for everyone that has a Q9550. Could you guys all post your VID's Please.. possibly with screenies.

There's a guy wanting to sell me his Q9550, and he says the VID is 1.1750. thats a pretty darn low VID, and it would probably clock like mad. So I'm wondering what everyone'd VID's are. and can you all post ur max clocks as well. Thanks!

That's mine vid
Look here

Prime 95 @4080Mhz

Prime 95 @4200Mhz ( didn't test with lower Vcore just set to 1,424 at random)

That is with CPU Cooler Zerotherm ZF120

You shouldnt make sweeping statements like that.
What your idea of stable is dosent make it law...others will have different opinions myself included.
12 hours of prime is rediculous, its like the guy that was telling everyone to run IBT 50 to 100 loops
Kill your hardware thats up to you, but dont advise others to do so.

if I were you I would look for a good S-spec / FPO number, cause I've seen low vid CPUs OCing worst than "high" vid ones. For my Q9550 both CoreTemp and RealTemp report 1.25 vid, but for some reason SiSoftware Sandra says Min Core Voltage 0.713V, Max 1.138V which is valid cause the CPU is perfectly stable at default speed with 1.1V the lowest voltage my mobo allows me.

[Hoss331]

Mines a 1.225vid and the highest stable clock so far is 487x8.5. It will probably go higher but Im not going to try for it until I get better cooling.

Highest primed is 8.5 x 500 FSB...

[les_paulde]

Hey everyone!

Just received my new Q9550 E0 chip 2 days ago to replace my Q6600, as it would not allow me to come near the magical 4Ghz border which I wanted to cross as part of my New Year's resolutions... Luckily, I seem to have a decent combo with my rampaged P5E dlx and Q9550, as crossing the 471fsb for 4Ghz was quite painless:



Stepping: L830B496, VID of 1.25V

The settings used are basically:
vCore = 1.368v
FSB vtt= 1.36v
vNB = 1.59v
vDimm = 2.06v (bios), 2.10v (real)

Strangely enough, it only needed 1.29vCore for 3.9Ghz, so I was quite surprised how much extra vCore it needed for a mere 100Mhz increase? I also needed to up the NB from 1.5v to 1.59v for the 4Ghz...

Also, I was wondering if there's anything wrong with my core temperatures, bearing in mind I'm under a dedicated waterloop with 3 radiators (water temp ranges from 33C to 37C). I've been searching a lot on what kind of temps people are getting, and these seem comparable to people on air so I'm not sure if my cooler is mounted right. The thing is that a lot of people still seem to be using the tjmax of 95C, leading to their temps being displayed as 5C lower.

Crossing 480fsb has proven more difficult, and while posting at 500fsb, it will not boot Vista, so I was just wondering what kind of results people have been getting with x48 chipset and E0 q9550, using what voltages? My aim now is to reach 500 fsb so I can run my ram 1:1 close to its rated speed of 533 at their tightest timings...

[cencik]

Nice clock work on it. You probably have all cores tem. stuck. Like mine 1-38c, 2-32c, 3-31c, 4-31c it wont get any lower even if i open all my windows and ambient is 7c. No a big issue as long i have good reads from load.

[seba84_2005]

Hi,

My new Q9550 E0 - cooled on water cooling

1h stable on Prime95 - VC in BIOS 1.28v

I couldn't get past 430fsb on the x38. I'd consider yourself lucky... either that or quite the talent.

[RacingTurtle]

Seriously guys could you stop showing off please
My VID is 1.1 on my EO and I cant get past 3.6 on this chip. Pretty sure I should be getting much more. Running it at stock as nothing is stable.
I know its not my board as I got 4 GHZ on my E8400 on it.
Any help? Think its a dud?

[cencik]

Time to review this thread.
Max(for now) on my x38 limited mobo and skills. 50c on NB is limiting me(40mm fan on it). I would like to have GA-EP45-UD3P to see full potential from this cpu. I can boot up to windows whit 495 FBS but not stable.
