Q9550 action inside

n7 · Oct 26, 2008

My results = headache.

Exactly as i'd expected, FSB limitations showed up almost immediately.

My P5Q Deluxe seems to really hate running 450 FSB or higher, & i spent all day yesterday trying every possible VTT + GTL combination in a futile effort to keep VTT (FSB Termination) voltage lower.

If anyone has any magical settings that work for IntelBurnTest & Prime 95 Blend/Large FFTs stability @ 450+ FSB for quads on a P5Q, please do share.

Anyway, on the to the pics & prelimary OCing results.

Intel partying hard.
The new & improved...smaller box.
Yes, it's E0
The chip.

3825 MHz Intel Burn Test stable...i think

Still lots of work to be done on getting voltages lowered yet somehow still keeping stable, which is seeming to be an impossible task.
And i haven't put in all 8 GB yet...just testing with 2x2 GB all loose...i'm scared that it'll get much worse when i go back to my full 8 GB.

Summary: Intel is a meanie for crippling these chips with lower multipliers; i'd be running well over 4 GHz on air if it wasn't for that :frown:

4 GHz...but not a chance in hell of getting the FSB stable

Thats how I was running mine at 1:1 with the ram, had to make a few changes with my HZ chips and running 12:10, but above was with the Pc8000 PQ chips. For some reason my setup needs that NB voltage to be stable, could be my Raid card doing it tho.

hey n7 where did you get your q9550 and did it happen to be not 400+ cdn?

Raventon · Oct 26, 2008

hi i have mine at 475fsb..although i am on the rampage formula with the x48..but i pressume the p45 will be better..

my settings are vcore 1.3v,VNB at 1.35v,FSB termination at 1.3(measured by bios at 1.2),both NB GTL and cpu GTL at 0.67..hope this helps

anyway the settings above is with 4 slots of dimm filled up

Look at the pictures more closely
The location of purchase is there.

It was $420

Prices have skyrocketed lately thanx to our dollar leaping into the shitter again.

I wanted an E0, so locally was really the only way to guarantee that.

Big Lar, thanx very much for posting your settings.

I am trying 8x455 (keep CPU max outta the equation for now).

I played some GRID while running P95 Blend in the background, & for that time it didn't error.
Of course, i'm now running IBT, which i kinda expect it will fail in.

Holy crap the difference between IBT w/ 4 GB& w/ 8 GB is massive though.

I now understand why people don't find IBT so insane like i always had (with 8 GB)

With only 4 GB installed, i was getting great temps during IBT runs, maybe only 5C higher than P95.

But i put my 8 GB now, & wow, the temps for IBT are suddenly like 10-15C higher :Q

Not sure exactly why CPU temps are so much higher with more RAM, but wow, they are.

Big Lar · Oct 26, 2008

I noticed you posted in the GTL thread in another forum we belong to.

With my setup, I started with 0.630 for gtl 0/2 and 0.670 on 1/3 gtl. How I ended up with 0.675 on 0/2= I would run Prime Blend, and when worker 1 or 2 would error out I would raise the gtl for those 2 workers, ie 0/2 in bios. When the gtl setting would not help, I would put the setting tried to last good setting and up the FSB/VTT 1 notch and try again.

I also found for my setup that if the VTT/CPU and GTL's would not let me clock any higher, then it was time to up the NB volts a notch. I didn't need to mess with the NB GTL until I hit about 1.3v NB and then it needed 0.635 up until 1.34v NB then it wanted 0.640. Kinda had to play with it alot to get the higher fsb with this board. Obviously my core 0/2 are much weaker than 1/3 which is why I need so much higher for those gtl's. Hope that helps. I also read that whole other thread and I just don't buy how they are setting the gtl's, at least in my circumstance with this chip/shrug.

TC91 · Oct 26, 2008

holy crap $420... i wonder if i should. Well best of luck with your chip, hope you get your 4ghz.

Ah okay.

I don't want to get excited yet, but IBT passed 5 passes of IBT @ 8x455 with your settings, something i could never get before.

It also just passed IBT "half RAM" 5 passes @ 8x460 :Q (half RAM since all RAM w/ 8GB takes ages to run).

I don't want to jinx anything till i run longer testing, but so far... *crossing fingers*

Big Lar · Oct 26, 2008

Great, at least you are getting closer I run xp 32bit so I have no choice but to run 1/2 the ram or a bit more in IBT. Nice test for quick testing but I found that Prime Blend does not always follow suit, but it at least will give you a range in which to tweak from.

Larry

n7 · Oct 26, 2008

I wonder if the key was the NB voltage + GTLs being set manually?

I dunno, just weird since i know when i was trying the whole range of VTT voltage + corresponding GTLs, i used settings pretty similar to what you listed, just i had NB GTLs at auto.

I see your settings pretty much all calculate to around 0.85...

Eh, 470 IBT just locked up the system :\

Big Lar · Oct 26, 2008

Could have been the NB gtl, I think some of these chips have a mind of thier own. I have noticed that 99% of the peeps with quads run thier NB gtl at Auto, that wouldn't work worth a darn for me, but yet others it does fine.. go figure. I also found that raising the VTT with this chip 1 notch too much will throw the whole damn OC out the window as well. Weird chips if you ask me!

Now if I could only figure out the right timings for my HZ... whole new chapter there tho.

Larry

Big Lar · Oct 26, 2008

"I see your settings pretty much all calculate to around 0.85...

Eh, 470 IBT just locked up the system :\ "

Looks like time to tweak the ram/cpu volts then. Yup my NB and cpu gtl tref matches for some reason, but I never planned it that way, just sorta worked out like that.

Larry

KingstonU · Oct 26, 2008

Have been planning on pushing my Q9550 for my first OC for a while but effing university won't give me a break and let me pursue other interests in my life

Hopefully in a week or two I'll get a chance to try.

Yes, thanx for this.

Seems you also are using settings somewhat similar to Big Lar.

And Big Lar, a big thanx to you!
Considering i was stuck at 450, your settings have pretty much been magical.

So far, so much better.

3.95 GHz (8.5x465) IntelBurnTest 7 passes good using your settings

Now i have a target in sight...4 Ghz of course, something i figured was impossible (perhaps still is).

vCore, RAM, nor temps are issues.
Just FSB.

What do you suggest to get 471 stable

Higher GTL for FSB/NB @ same voltages, or more voltage with those with the same GTL values?
Or should increase voltage & decrease GTLs?

Edit: ah crap, OS just froze during P95 blend at those IBT "stable" settings.

Big Lar · Oct 26, 2008

Nice job so far! I would try a tad more cpu voltage then try and mess with the GTL's, usually for me if Prime Locks, its either cpu or NB volts, tho when you are living on the edge, could be a combination of all the settings. Your welcome of course and I am glad I could be of help

Larry

ps. Nice chip

Big Lar · Oct 26, 2008

I should have added before that the 1.28vtt is good on my board to 483fsb, however, sometimes if you need to raise the cpu volts a bit more, you'll need to up the vtt 1 notch, Without having to mess with the CPU gtl's. Funny stuff eh?

Larry

556fsb here:

guy says, secret is vfsb, vtt, and modular +12v rails.

n7 · Oct 26, 2008

Bah this is frustrating.

Gotta stop the OCing for now as i need to prep the PC for some LANing tonight.

4 GHz IBT 5 passes

But P95 Blend errors a few minutes in.

Patrol · Oct 28, 2008

wow that's awesome, Big Lar your the man, very nice that's aming keep it up very very nice

n7 · Nov 1, 2008

Upping this in the hopes someone has some more settings they can share.

I haven't spent much time on tweaking since last weekend, but i'm still unable to get P95 Blend/Large stable for the higher FSBs

I've run 8.5x465 all week long, & it runs stably for all my gaming & normal use, but i like to see things pass P95/IBT, so i'm still looking for more insight on getting higher FSBs stable if anything has any.

Cpu overcharging mode: 1000mv

Try playing with skews, a 1:2 ratio between cpu and mch is good e.g. cpu 100ps/mch 200ps-300ps/ or cpu 200ps/mch 400ps. Set these before you start tweaking the gtl ref. Bump your pll voltage to 1.6v-1.7v. Run prime95 blend instead of IBT. It will give you more clues to such error when tweaking your gtl ref. Last but not the least, replace the stock tim under the NB/PWM. This generally helps stability at 470fsb++

There isn't a CPU Overcharging Mode on the P5Q Deluxe. Also 1.6 to 1.7 is a bit extreme for PLL isn't it. I'd say the rest is great info as to the skews tho.

I could really use some help with this too. I am brand spanking new to Anandtech, and OC, and this was my first build. I have read posts, here, overclock.net, and various other places, tried all kinds of settings I've read about. I run coretemp, realtemp, CPU-Z, HWMonitor, Everest, Intel Burn Test, Prime 95. I'm really not sure what exactly the settings I'm adjusting are doing so this is difficult. I understand raising and dropping voltages, heat, that kind of thing. But I don't understand how the correlate to each other, and what effect one has on the other. Anyone with some good knowledge want to baby step me through these settings, and the abbreviations for the different settings really confuse me, since they seem to be worded different on every mobo. I don't want to come off as though I'm unwilling to learn, I read, read, and read some more, but I'm still not getting this stuff. It really pissed me off tonite when I was reading some guy got 4.0ghz out of this chip with a little nudge on vcore and didn't change anything else. Any help would be appreciated.

Edit: Hot Damn I just passed IBT 10 runs at 4003.8 MHz gonna set up prime and go to bed, maybe since I cried a bit about it, the damn thing will start working.

Edit 2:
I got this thing fairly stable, as far as what I see. I'm new so I may be wrong. I got it to run 10 passes on IBT, so then I went and let it run 10hours on Prime95 and all worked out so far. Now I could use some help maybe fine tuning, or OC'ing the memory. Maybe I don't need too, thats why I would like some help fine tuning this. I'm posting the bios so you can tell me what it is I could or need to changed. I don't know what all the abbreviations for stuff mean, so if you could be so kind as to tell me what I could changed according to whats in my bios it would really help me. I'm learning, and appreciate all the help I have gotten here.

Welcome to the forums jjrowley (somehow this post got put above yours )

If i ever get it figured out, i will post the settings i used.

TBH though, i'm pretty near giving up & just sticking with a lighter OC.

I have tried so many different combinations of lower & higher voltage & different GTL values, & now CPU/NB skews, i'm pretty near going insane.

It's like looking for a damned needle in a haystack.

I'm really good at isolating issues in order to determine what is causing the problem so i can fix it...

But with this, i really don't have anything to go by, & when you don't have the tools to narrow down things, well it's pretty futile.

I'm noting most of what i try on notepad for reference, & just when i think i might have narrowed down what i need to work on, it goes & fails in a way that doesn't jive with previous results.

/pulls hair out...
