The E0 Q9550 SLB9V thread (finally!)

[MacClipper]

Spent the last few days tweaking for this chip to be used in a SS SG-01 (this post is mostly copied from my VR Zone post).

After a day of tweaking downwards (on the Puasa public holiday), this is what I got for now. Had also flashed to the new 0901 BIOS with official E0 support for the DFI P45 Jr, Vdroop Control is Enabled (default).

3.8GHz@8.5x447@1.23/1.23 Vcore/VTT with 10x IBT load temps of 58/58/56/56C (Singapore ambient ~24-30C). vNB down to 1.42v but yet to optimise vDIMM though, looks like unfinished job for later.



Short OCCT run to double check actual load Vcore and VID sensors,


Looks like it might be a go for 3.8GHz in the SG-01 after all.

Check out the VR thread, there are 2 good 4GHz clock guys in it too, kindly ignore the little spat about batch info if you can.

Enjoy!

PS: EIST/C1E is enabled as seen.

I suggest you add C1 to the thread title so we can see how both variants of the Q9550 clock side by side.

HI, is there any place to buy them yet?

thanks

Not in the USA or Canada. Most of the guys with these chips are having them shipped in from off shore locations. Cheaters!

Early looking at 4GHz,

Retail Q9550 @ 8.5x482 - 4.097Ghz

You are still welcome to post yours here for comparison, that's one nice o'c for a C1.

My lousy Q9550 doing 3.2-3.3 around 1.26v... on DFI P35-UT board though...

anyone using C1 steppings Q9550 on P35 UT ? mine to share the GTL references values... i tweak mine and very confused... now running 61-61-61... or any idea of GTL reference values on a 45nm quad ?

cant seems get the GTL values correct as i need high vcore for 3.4,3.6 and so on...

I'll post mine, not as nice as your low volter but temps are great and vcore is 1.43 bios

L820B047 for a start. lower then vid oc

4GHz done.

The 4 phase Jr mosfets do get a real good working out during IBT, ouch!

[RealTelstar]

Interesting cpu and interesting mobo.

[carepolice]

Nice results on your 9550, It makes me think why i bought C1

more heat during the cold winter?

[carepolice]

more heat during the cold winter?

OK, This is the thing +26 even in winter > low volts on E0

[moogle]

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

Haha lucky bastard

My chip is maybe the first one made 7/23

I'll go check those codes that are on the box to see when my one was made.

Mine was packed on 9th of June 08 06/09/08 (US Date though) and the week is 15th. So am I right in saying it was made in April?

And your VID was..?

[Peen]

My C1 primes 3.8ghz @1.25v but just curious how tall was the heatsink your Q9550's come with? Mine is only about 2 inches tall! Looks like a damn laptop heatsink or maybe a heatsink for a 486

[moogle]

And your VID was..?

1.15V
Am I more of a bastard now?

[xguntherc]

Nice results here guys. I couldn't wait for the E0 to come out. So I snagged a Q9650 instead.. but looks like you guys are doing great.

Also, The Q9550 E0's are Now available on Tankguys.com for $350 for sure E0's.
Also as of 10/08 Newegg.com has started shipping E0's. Everyone that ordered after 10/08 so far that I've talked to has a E0.. It's probably not a For sure thing with Newegg, as they ship from all over. but They have moved plenty. as the Q9550 seems like the New Q6600.

Good Luck Guys!

Deffo shorter than the Q6600 one.
