Ooh I'd forgotten about this thread.
I'd better post my 3.9ghz 1.29 vcore stable before I RMA this board.
I'll do that tonight, if anyone is still reading.
Oh and, Johnny, try burntest there. I think you'll see some...surprising...temps.
I'd bump down the vcore if i were you.
Yeah Vcore is a bit too high for my liking but temps under stress test progs like prime and OCCT are acceptable.
Think I may need to increase the VTT to reduce the Vcore right?
I haven't touched VTT on my P5Q3.
i do have 1.6 vNB though.
how much have you toyed with vcore? I bet you could go lower =]
Is the CPU V-Core that CPU-Z reports accurate?
I ask because on CPU-z my Q9550 @ 3.4Ghz (8.5*400) shows a voltage of only 1.152v. That sounds really low to me. Can the CPU-z voltage be trusted?
as long as u are using the latest version, yesQuote:

I think it's pretty accurate... do you have an E0 Q9550 Relik?
@slovnaft.... I had prime95 give an error twice after about 3 hours so I increased CPU PLL, VTT and Vcore a bit and now it was stable. Could it be that by increasing vNB I could do with less Vcore?
Actually not using the blitz anymore, gonna sell that. I am on a Gigabyte GA-EP45-DS3R right now. I think your right about the voltages. I have it set at 1.25 in BIOS but it is reported 1.152 in CPU-Z latest version.
Anything I can do to fix the discrepency?
Johnny - It is actually C1. Nice chip though.
using load line calibration? turned off C1E and throttling options? on my board I have VID and VID special add, I do not know about the gigabyte bios though...
Don't think the board has Load Line Calibration. C1E and all the throttling options are off. I'll have to check on the VID Special option. Pretty limited on this board I think though.
that sounds about right.
CPUZ is generally accurate (with the exception of BlackOops..lol...) at volts
I've never used anything else.
And that kinda voltage sounds OK and pretty good for that CPU.
@Johnny
Yes.
and maybe it's me, but I don't like playing with PLLs and VTT, just like i don't like playing with gtl refs. I don't entirely understand them and they seem to be the less flexible and more dangerous voltage settings.
Thanks for the help Slovnaft! Any idea how to get the board Voltage more accurate with the drop in windows?
hard volt mods to the board.
what you're experiencing is vdrop. It meanns that the BIOS is setting one voltage, but because of resistance and inefficiencies in board design your CPU is really experiencing another.
When this differential is constant it is called vdrop, when it gets larger with cpu load it is called vdroop. many boards have Load Line Calibration which attempts to compensate for vdrop or vdroop by estimating it and delivering higher voltages than specified at load, attempting to maintain the set BIOS voltage.
In essence, CPUZ is registering correctly, your board just has vdrop. What you can do is set the voltage a touch higher than the voltage you want. As long as you're not shooting for huge volts, you should be fine.
If you've got a soldering iron handy and don't mind taking a risk, you could look around for a hard vdrop mod; usually soldering a variable resistor here or there, to remove the discrepancy.
But these are board-specific and depending on the amount of attention your board gets from the community there may not be any solutions for your board.
what I like to do is decide the max voltage you're willing to put through your cpu for the kind of clock you're trying for (24/7, benchable, suicide run), set that, and baseall your OCing off that voltage, reach your max clock, and undervolt later. basically accepting vdrop as a limitation of your board and not risking setting voltage higher than you may want, as it can spike up in transitions from idle to load or vv.
Great, thanks for that info!
I might as well leave it alone for now. It is completely stable at that voltage and clock.
I don't even think I can take it any higher. I have my Ram at 400 which is what it is rated and I'm not sure how well it can overclock. Im sure the chip has quite a bit more in it though.
http://www.newegg.com/Product/Produc...82E16820145194
That is the Ram I have, here is some more info on the chip they use TWIN2X4096/CM2X2048-6400C4DHX XMS640X v1.X PSC 128MX8
You think these have any room to overclock at all?
I have a 10 Degree difference at Idle between cores1 and 2, should i be sending this back for a replacement?
by 1 and 2 do you mean 0 and 1 as in the first two cores or the middle cores?
if you mean the first two cores then this is normal. If you mean the middle cores then, well, i mean it's not terrible either. you could send it back as an excuse for a batch update, get a new chip take a chance at being higher binned, but it doesn't really matter.
reseat your hsf if you're really concerned, and you could probably try lower voltage to get your temps down.
yeah i mean the middle cores, tried reseating made no difference don't know that i can kower vcore much cause i am at stock. This is my last upgrade for a while so want everything just right Think its going back
eh why not.
get a new chip, roll the dice again. i love doing that.
stock volts for 45nm is like, 1.1 i believe. at least, thats what my P5Q3 set it to.
with what are you measuring? When I installed realtemp the first time I had a 10 degree difference as well but found out that the tjmax for 2 cores was set differently from the other two.
coretemp, realtemp and everest
and btw tjmax for Q9450 is actually 100 not 95.
ok i just got a used q9450 and popped her in, now for some oddball reason its idling 33-34-22-31
ive reseated it twice benched it, and stressed it and all 4 cores are working but for the life of me i dont understand why the temps are funky. btw i just upgraded from an e6600
i am using a storm g4 block. i think that might be where my problem lies cause i am noticing cores 3-4 temps are solid at idle where as cores 1-2 are fluxuating up and down by 2-3c
should i invest in a dtek with quad core insert? or are there any better quad friendly blocks. i havent OC'ed yet because i want to get this temps thing cleared up before i cook my new chip
People need to read up on the diodes on these chips
they are not meant to give accurate idle temps their primary purpose is to provide accurate load temps and trigger thermal throttling.
Your cores recieve unequal load and thus have varying temperatures.
As long as none of your temps are crazy under load, don't worry about discrepancies, especially in the cooler direction.
New, small issue... With my current strap vs FSB settings I can either run my memory at 1140mhz which I can do at 6-5-5-20 1T settings or I can choose for 1540mhz. I have switched back to 2T and loosened the timings to 7-7-7-24. I did 10 runs of memtest86 test 5 and it was ok but the problem is this. As soon as I start up a game it hangs somewhere during loading.
What would this indicate? Do I need to increase NB voltage since the memory is pretty much stable during memtest or do I need to increase DRAM voltage to get it to work in games as well?
First all, thanks for this thead, a ton of info here - anything and everything you need to know about the Q9450 is in here. So cheers! :up:
I was hoping that someone could take a look at my settings and suggest any possible improvements.
I’m currently running at 3.4 Ghz stable (linpack 10x, and Prime95 12hrs+)

I started at a vcore of 1.33750 and have slowly dropped it down to 1.21875 doing linpack 10x every time I drop the vcore.
SO I decided to post here about my recent bad/good news.
The bad news is that my Q9450 is dead, probably from trying to push over 4ghz with more than 1.5v. The good news is intel is great about replacing chips pretty much no questions asked, and I should be getting a brandspanking new one on wednesday.
So I would warn anyone, especially those with P45 boards, against pushing even to 4ghz, as it could kill your chip more easily than most. I only spent a handful of hours altogether making abuseful attempts on my chip before noticing that it would no longer post at stock. moving it to a new board confirmed, it's dead.
Where did you come up with those gtl ref #'s? Kinda surprised at that is all. After tweaking my gtl's I ended up with:Quote:

I guess my CPU or Motherboard just sucks? I must have wasted over 48 hour straight playing with this, and I keep going back, to 3200 MHZ completely stable. Its very strange to me I guess my intel just overclocks like asz.
When I say stable I mean at least 50 iterations of Intel Burn Test, often it will fail onyl after 20 tests or so.

I've never had a system that was 2hr OCCT stable crash on my before so that is my stability benchmark.
Those GTL ref are JACKED up... .37 and .75? The difference between those 2 numbers is something I never saw before and thats across 3 forums. Something just doesnt seem right. I cant believe that is stable at all on those cores.Quote:

I have spent over a month total trying to go higher, I have only managed to do so with 4GB memory and alot of voltage. I feel much better knowing my CPU can take anything I throw at it and will be stable. Sure nothing loads it up like burntest but thats not to say it will never make a mistake unless it is under a load. 50 iterations of Burntest takes about 4-6 hours to complete with 8 GB of memory. I think tis very reasonable.

So I should lower those figures? What's an "ideal" figure?Quote:

I've now further dropped the vcore to 1.16250 - IBT stable, currently Priming.
Naa... if it works... I gues it works. Default values for those are .67. Ive never seen one as low as .37. Same with the NB GTL.
I'm gonna try those default values tomorrow, just out of interest.Quote:

Thanks for your help dude :up:
To each his own, I want more MHZ, just not badly enough to be less stable. Theres not a huge difference in 3200 to 3400 to 3600 anyways. I mean sure software isnever going to be 100% stable on windows anyways but as much as possible is #2 importance for me, #1 being that I don't have any leaks in the water cooling.Quote:

I have both of mine set to .63 and my fsb term is 1.22 "that one won't do less then 1.22 for sure" and my Core voltage is 1.245v~. I haven't tried to drop it in a while..
wow, 3.85 on 1.248vCore, nice gtl tweaks!
That is pretty awesome voltage! I'm jealous!Quote:

i never fooled around with them because i didn't quite know what to aim for.
I know that this is about 9450 but well 9450 & 9550 is nearly 1:1.
I cant get grip of my cpu!? Its so full of suprises! I have always tought that it likes applevoltjuice, but i first tested whit 3,8ghz clock boot whit vFSB 1.32V ! Well then i rebooted and changed vFSB 1.10 wich is well known as 45nm default value. Doh system booted and is working fine:confused:
I have to keep high vcores always on high OC's, But when i try play whit NB and this vFSB voltages i CANT lower vcore even for one snap! I can just run whit default vFSB and vNB on 1.26 whit high vcore:down:
Feels like that my CPU is scumbag who just likes only kind of volt! :mad::mad:
in few words = Why my vFSB & vNB doesnt make any difference, any value that i give?
First off, 1.26 is a pretty low vNB especially for FSB speeds 450+. When pushing high OCs on this chip I get stable around 1.4-1.6vNB depending on the board and chipset.Quote:

If it won't post on another board then you've probably killed your chip, but don't worry, intel will RMA it as long as you throw a bunch of technical terms at their RMA support.
I run a 9450 on an Asus Striker 2 NSE and just by putting up the fsb can run it stable at 3.6. I run SLi with a BFG 9800GTX and a Asus 9800GTX+ and on Futuremark '06 score 19848. So believe me when I say I love this CPU I found that running with the water on both the north/cpu keep temps below 25 even after a couple of hours of gameplay. I shifted from a Q6600 and the difference is extreeme.You do need the 1002 bios and nvidas newest drivers, as previously I had nothing but trouble. So good to see there are some real people out there. But has anyone tried the 2.8 I wonder how sweet it must be.
Thanks for feedback!Quote:

Ill try increasing my vNB for a little bit, and i have started to look at these GTL tweaks, maybe ill take a tour on them and start from 0.63xx ->
Would another bios make any difference?
Yah I guess I got lucky with my chip huh guys.. :up: I actually thought about selling it for a minute there for around what I paid for it because it clocks so well.. I am on air here so I can only imagine what a good water cooling setup can get this chip to do or even LN2, hell it might break a record with LN2. I have decided to keep the chip though..
Yah it really melts my faceeeeee!:horse:Quote:

most don't require much voltage to get close to their max stable clocks (say 480-490 fsb, i got 495 stable at 1.27 =D) and temps are really good in general, but then to get to 500fsb and over the voltage regression seems to become exponential, meaning that to push 500 and over it requires upwards of 1.4 and 1.5 or above for 505-510. so if you're pushing enough voltage for temp to be a problem, you're probably going to need to use that intel warranty. I know i was relieved I hadn't lapped when my chip died.
But what did lapping get you? i would think that the gain would be under 10C as these chips already get great temps.
I don't remember 6c each core I think.

Would like to see IBT 10x and maximum temps for that. Also, you need to run P95 for atleast 8 hrs (imo). 12hrs+ if you can. I can get my boot system to boot at 3.8 Ghz, doesn't mean it's stable ;)Quote:

I need to try dropping mine again to see if anything has setteled yet.

Yeah, my HS is screwed down as far as it will go, without bowing the board. However, I can still move it slighty, with a little force. Think I might need to mod it a little bit (penny mod?).Quote:

My only concern with 3.8 Ghz is the temps I might reach with IBT, but as mentioned before, nothing stress my system like IBT. IBT did cause my system to shut down once, temps shot straight up to 70's and the system went haywire. That was a scary experience :shocked:
Thing is, the settings for 3.4 Ghz & 3.6 Ghz are completely different (excluding the obvious ones) - I'm talking about the GTLs. Might go back and use the GTLs for 3.6 Ghz on 3.4 Ghz see what happens.
careful with clamping down that HS too hard, you can pinch resistors and such and potentially cause your board to give errors on POST. i thought my newest board was DOA until i loosened the HS a few twists.
I need to penny mod mine to I think..
GA-EP45-DS3R and Q9550
3.4Ghz - All I did was change the vcore to 1.3v and FSB to 400 :) Lots of testing/tweaking left.
You could probably drop the vcore to at least 1.2. Don't need that much pumping into the chip, in my opinion.

wow, nice temps!
On another note, anyone have any experience with this chip on a 790i board?
Gotta love water, or really cold air conditioning lol.
it seems that i´m bad whit my sets.... look:
vCPU= 1.375v
vFSB= 1.350v
vMCH= 1.425v
FSB= 430Mhz
multi= 8
memory= 1718Mhz
Ref= 400Mhz
idle= 34ºc
load= 51ºC
Aux(i think this is northB?)= 33ºc
gtls and ttl when i get home
Well managed to sort my temps out, they no longer brush 70c, and they hold steady at 65-66c. Vcore is at 1.20000 exactly. Working on dropping all the others voltages, will share my settings when I find the lowest possible stable settings.
Also, has anyone noticed that this chip (maybe others aswell) has like a "break in" period? For example, I ran IBT last night with pretty much the same volts, and ran it again today, but this time the temps weren't as nearly as high. A good 5C difference.
That's pretty impressive, whats your setup? Also, could you please share you BIOS settings?Quote:

i´m lowering the Vcpu now, i have it 1.325 and geting down
Well according to this. It's 'VID Voltage Range: 0.85V – 1.3625V'. I'm sure there's a little give/take on that range though.
Tried 3.8 Ghz last night at 1.25000, everything was going well with the IBT test, and then it froze half way through. Mind you cores 0 & 1 had been on 70c for a couple of minutes. Guess I must have tripped the ProcHot switch :eek:
I wonder if I can do 3.7 Ghz then :D
Its something other than vcore because I upped it 200mhz to 3.6Ghz and I'm playin with the same vcores actually sometimes it runs slightly lower. Temps seem fine though says 31C now idle and max was 58/58/56/56 with all four cores buringing in.Quote:

Glad I could help.
you need your VTT voltages to calculate you gtl's it's simple math VTT * Gtl's try to find in witch spot is better for your chip 68 until 70 is ok for daily use if you do the math that is ~ 0.9 to 1.1 Volts :) test it and see where it behaves best my chip likes better 68% Gtls with 1.43 Vtt witch is 0.97VQuote:

but i´m unestable, some where i had read that for 45nm quad gtl´s by rule are more or less 0.63, is that correct?
lol at the droop (BIOS is at 1.325v)
WOW that is some droop!
what board? perhaps you need to break out the soldering iron...
Gigabyte P45 DS3R. Prime is still running just took a screen shot to show where I'm at. Mind you stock was only about 95% stable with this Chip on my 680i board!
I actually had pretty bad vdroop on my gigabyte X48T-DQ6, that's why I RMAd it. wonder if this is characteristic of gigabyte boards or just bad luck?
guys, i need some help...:confused:
Which is the max Vtt and Vcore i can give to this chip before it begins to electromigrate? also which is the max Vnb(Vmch) for a x38? :up:
Well I've decided to give up on 3.7 / 3.8 Ghz for now. The system locks up during IBT - out of the 5 runs I did, it only managed to complete IBT once, and even then the temps were insane, never leaving the high 60c's and sometimes brushing 70c. It's a far cry from my 60c max temp with 3.2 Ghz. I'm happy at 3.6 Ghz for now... :up: Yet to do a P95 run on that though (12 hour run). I'm starting to think my cooling isn't up to scratch, or might need a push and pull fan setup on my TRUE.
:eek: Wow! Have you enabled Load Line Calibration that's meant to reduce the vdroop (or vdrop?).Quote:
