The E0 Q9550 SLB9V thread (finally!)

[Aleki]

cincyrob,
I just picked up that exact same batch you have
Coincidentially, I also have single sided 4x1gb crucial ballistix 800mhz. these really suck in comparison to the double sided ones I had prior to their death (they did 1GHZ @4-4-4-12 2.1v)
Coincidentially..(X2), I have the UD3P board everyone raves about
I havent popped my q9550 in yet since my UPS battery died, and I am waiting on new ones which should be in by next wednesday. Although, like you, I feel these sticks will choke down my processor and keep me from making any progress

PS: Just throwing this out there to anyone who wants a handpicked E0. I am heading down to boston tomorrow (and next tuesday) to drop off my car for service. Would anyone like me to pick up a E0 for them at the local microcenter? currently going for ~180 after tax, and I believe they are still carrying the L846B715's. PM me if youre interested

I 45 checking in at 3919.9Hgz (Stable)


bios setting



O now for the passing Grade



this is another intelburntest shot below after dropping the cpu volts [+0.75v]
gonna drop the volts some more once i get her back in the Case



shot of setup out the case My Cooler Master 590 has been repainted on the inside waiting to get a few more new upgrades for the motherboard b4 she goes back in

i'm not gonna hold it here at 3.9 after all is back together lock it at 3.4 that's good enough!!! another thing core 1 and 2 run at 31c and 3 and 4 26c at idle temps out the case different story once it get inside the case with more fans blowing

That's where I just bought mine today. Down to 23 in stock in Cambridge MA. I can confirm mine is an E0 (SLB8V). Don't know the VID yet.

Just installed this and I have a VID of 1.1000

I feel like I just won a lottery. I am just prime95 small fft at stock now to see what the temps are. My Biostar I45 is giving it 1.184V under load. I'll report back with more numbers when I get a chance to OC.

[lordmagnum]

what is the best soft between prime95 and Linx (or Intel Burn Test) to check the CPU stability ?

[Kashelz]

Damn, looks like Im out of luck

Got my Q9550 E0 with batch of L845B612, i hope B will still be good (all my Bs have been nice), but it have very high VID for E0, its 1.2750v All my best Q6600s have 1.2750 or 1.2625v, lets hope it will shine

BTW Im on my P35 P5K-E with 1305 BIOS, with Q6600 I can get ~ 480 FSB with 8x. Hope it will take faar and pas 4+ Ghz.

Well that was fast. I went for the hail mary pass into the end zone and got 475X8.5=4.05GHz @ 1.3V. My temps on core 1 seem out of whack (8C hotter than core 2) so I might need to reseat my heatsink. That is a pain because I have the bolt down kit and I have to remove the motherboard to do it properly.

Maybe I need to lap this puppy....

I thought I could attach images directly but looks like I have to host them somewhere. Will post images when I get that sorted out.

It's almost impossible that all cores have the same temps.

[Dadi_oh]

It's almost impossible that all cores have the same temps.

My Q6600's cores were always within a few degrees of one another under Prime95 small FFT's. It is a pretty balanced application. It is possible that the IHS on this particular chip isn't making even contact with all the cores. I hope not to have to reseat this. It is a PITA.

[lordmagnum]

Can a CPU need more volts after some years of use ?

A LOT of the 45nm quads have at least 1 sensor that is out if whack. I have had several and everyone has had a bad sensor on 1 or 2 cores. Just go by CPU temp in Everest. Good luck keeping that 1.1VID cool.

[Dadi_oh]

Yes. I have heard that the 45nm parts in particular can have degradation at higher volts. Shows up as ever increasing instability requiring more and more volts. Has to to with the new metalization layer technique they used on the 45nm process iirc.

I hope that is what it is. I thought the issue on the 45nm quads was stuck sensors though? That shows up when you drop in temp and one of the sensors doesn't go down to ambient (still reads high). That doesn;t seem to be the way mine is behaving.

I am going to try the stuck sensor test built into RealTemp and see what it says.

[OC Nub]

Yours may be different but I have had this same issue on several 45nm quads. I don't even look at the cores anymore, just CPU temp. I have reseated the HS before, on this reseated the waterblock but same results. On my other q9650 I lapped the chip and the TRUE and was able to even them out a bit but never perfect. Look at maximum temps in RealTemp in this SS, it is not just at idle.

I've also heard that LLC + high voltage agrave this happening.

Edit : I have a sensor stuck to 38°C, too. But It can exceed 38°C.

So you are seeing about 6C difference as well. I like that answer because it means I'm not tearing apart my setup to reseat the heatsink

I have sort of an internal gut feel that I don't like to see my cores over about 65C max with Prime95 small FFT. What sort of max temp do you reckon for CPU temp? I assume CPU temp is a calculation done by the motherboard to approximate the IHS case temp?

I will stop Prime if the CPU temp gets above 75c, it will never get that hot in any other normal thing I do so I am ok with up to 75c in Prime.

Just installed this and I have a VID of 1.1000

Can you post a pic of realtemp where is shows min and max vid?

[lordmagnum]

I rather think C1E and Speedstep are enabled, lowering the Vcore.

[Dadi_oh]

I didn't know there was a range of VID??? I thought it was just one value.

My computer is just running an installation of Win7 RC at the moment. I will have a look at RealTemp and see what you are asking for. I just click the upper right button cycling through the items until it displays VID. It only seemed to show 1.1000V as far as I can remember.

[Kashelz]

I have strange temps too, I have disabled all speedsteps, but idle temps ar the same all time @ 2.83 Ghz or @ 3.8 Ghz, 38/35/35/40, load temps with Intel Burn test is max 53/53/53/53, strange CPU. I have good watercooling oc CPU.

My stock voltage is 1.275v, with it looks like I can burn till 3,7+ and more Ghz, but when I get ~ 450 FSB it freezes whatever I do, even with 7x multi, strange, trying all setings. Maybe need another Q9550, I could burn 470+ with old Q6600 easy

[Dadi_oh]

I rather think C1E and Speedstep are enabled, lowering the Vcore.

But Vcore and VID are two different things. I initially didn't have C1E disabled (turns out you have to disable it in 2 different places in the I45 BIOS). But I am now running with C1E disabled and the Vcore showing 1.272V with the Q9950 at 475X8.5-4.05GHz.

The VID still shows 1.1000 in Realtemp.

Are we talking about two different things?

It might be that you have a FSB hole. Try setting the multi to 7X and then jump straight up past 470 to something well past 450 (like 490 if your mobo has shown it can handle it). Worth a shot...

[Kashelz]

Looks like bad CPU or bad combo with my board (maybe BIOS???), I cant find where to mesure FSB voltage on my P5K-E board with multimeter upside the board, 445 fsb passed Intel Burn test 50 loops easy with 445 x 8, but no luck at 450 I tryed FSB voltage all the way up to 1.4v from 1.1 in BIOS, tryed PLL voltage up to 1.7v, looks better, but also freezes during test.



Lets hope it is just a bad fsb hole with this cobo, never had problems on my 65nm quads

[Dadi_oh]

Check out the Real Temp thread

Oh. Looks like I was using an old version of RealTemp. Downloaded the latest and now it shows min VID =1.1000 and max = 1.2500. Does this mean my VID is 1.1000 only when running C1E power savings and 1.25V when running full power?

I would post a screen shot but this forum doesn;t allow me to upload images directly. I registered on imageshack and been waiting 4 hours for their confirmation email. Anyone recommend a faster response image hosting site?
