Q9450 OC / Temps / Settings

[carepolice]

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.

Second, what's the highest you've ever had your vcore? Instability at varying settings could be a sign that you've fried your chip. Try booting at stock everything. If you can't, try seating it on a different board if you have that option. 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.

Thanks for feedback!

In my previous post i didnt mention value of my "highest vcore". And i have always kept my Vcore in safe value, 1.25->1.36! Once tried 1.4V (bios); CPU-Z 1.38! (but didnt like "pushing" my cpu) CPU works 100% on default settings

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.. 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..

what batch is your chip?
I'm about to get the newest batch as RMA from intel.

It is week 813.

I wrote it down before lapping her.

[Slovnaft]

ooff imo lapping these bad boys is a really bad idea.
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.

[truehighroller]

I don't remember 6c each core I think.

P95 (12hrs+) & IBT stable (10x & 20x)

P95 (12hrs+) & IBT stable (10x & 20x)

Your fsb term won't go lower then 1.26? Mine is set to 1.22 it won't go lower then that at my speed.

[Singh400]

Wasn't working on my vtt today, was doing my nbvt (got it down from 1.40). But no, last time I tried drop it - it wasn't having it.

I'm confident I can drop vcore, vtt and vnb a little more.

[truehighroller]

You should be able to achieve higher speeds with your setup I see in your sig.

[Singh400]

I know I should be. Been trying for 3.6 Ghz for a while now, but it's just not stable.

I can get into Windows with 3.6 Ghz and run it like normal, but IBT fails (10% pass rate) and P95 errors out randomly.

[truehighroller]

I just posted my settings over in the P5Q Deluxe post try my settings.

I will do mate

[Singh400]

Passed IBT (10x) @ 3.6 & 3.7 Ghz (will P95 later, need to sort out temps). Thanks for your settings. I'm a little concerned about the temps. They are touching 70c If I don't get the temps below 65c, then I'm not gonna risk it and I'm gonna drop back down to 3.4 Ghz.

I am using a thermalright Extreme and have alot of case fans, but actually if that is under IBT then that is ok.. I get around that where I am "under IBT" that is about right probably. IBT realy heats them up good, no other program will stress your stuff hard enough to make it that hot. P95 will prob hit 66c is my guess. Your welcome as well.

What temp software are you using?

Yeah, I'm using a Thermalright Ultra 120 Extreme. Yeah I was just thinking about that (last night), nothing I will ever use will stress my CPU as much IBT, hell not even P95 reaches those temps. I'm gonna see if I can get 3.6 Ghz stable + lower voltages. Cheers again for your settings Then I'm gonna move onto 3.8 Ghz.

RealTemp mate. Don't trust anything else, CoreTemp is out by miles and so is everything else.

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

Your welcome, if you have your heatsink seated well and good gunk on it then 3.8 all day should not be an issue for you, it isn't for me. Then once you think you have it stable enough try dropping your voltages and see what you can get away with dropping and that will lower your temps even more.. 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?).

Well I was running 3.4 Ghz at 1.17500 (dropped this down from 1.33), and I've currently got 3.6 Ghz at 1.18 (I'm at work, so I'm relying on memory). But that passed a full stress test on IBT 10x. I'm pretty sure I can drop most (if not all the voltages) by another couple of notches.

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

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.

[Slovnaft]

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.
