Just got my retail X3350 from the same batch L803A756 from Moogr.com. Gonna rebuild my system with a GA-P35-DS3R. Might lend my chip to a friend to review on his site first though.Quote:

No problem, stock voltages, 4x prime95 stable overnight. Also tested the RAM at 500. No problem, but it's rated DDR2 1000. Then I dropped the multi to 6x and set the RAM to 1to1 to see how high I could get the FSB. Much to my surprise I could only get to 425 FSB. With the CPU at 2.55ghz I know that wasn't the limiting factor. Also, cooling is not an issue. Water on CPU and northbridge.Quote:

It's almost as if Intel has put an FSB limiter in the Q9450. The CPU is clearly capable of higher speeds, as is demonstrated by the test run at 8x. But problems at FSBs over 425 stop you from ever doing serious overclocks with it.
Could it be an electrical design problem with the chip? The Board? A bios problem? Dunno, but this build plan is not working out. Maybe I'll try a Q6600 I have laying around next.
That's the first thing I do when I start out with a new CPU. ;)Quote:

This new Q9450 does 455 on air so it will be very interesting to put on the Vapo in a couple of days... :cool:
I am looking forward to my own build. :D
Q9450 and maybe 2 GPUs.
And, of course, water cooling. :D
Im just saying that I have seen quit a few 790i mb's that are running the x3350 and q9450 at 450fsb easy and your mb but my mb bios have been a mess. Every time I go to a new bios I have to redo the dividers for my memory so its stable. I am just waiting for ASUS to get off there ass and give is a good bios, I just think thats what is holding me back from 450 fsb.Quote:

It seems to me... up until this point, like it's the board's limit rather than the chip's. Most X38/X48 boards are reporting 425-440 FSB walls, most P35 boards are reporting 450-460 FSB walls, and... most 780i boards are reporting 470-475 FSB walls. Coincidence?
Yeah thats what I am talking about, hopefully we will get the bios's that will remedy this problems over time. ASUS has so many damn motherboards out no wonder bios updates are slow.Quote:

My Maximus Formula (X38) could do 440x8 with a Q9450, but couldn't do 450x8.
Sold it on eBay.
Awaiting my X3350 and X48 Asus Rampage. Really want to run it at 475x8 for Benchmarking.
My X38 DS4 will do 484....
Lapped my scythe zipang today (was anything but flat), now though I feel like lapping q9450 badly - since it also just has bent in the middle. I know doing so without even testing the chip first is not very smart thing to do... It's just the thinking that you will have to deal with the installation of the heatsink with the :banana::banana::banana::banana:ty push-pin again brings crazy ideas to my head :)
Will proceed with installation tomorrow... hopefully first numbers will also come soon.
p.s. I officially hate push-pin design :rolleyes:
Yea i agree push pins suck and it seems im always questioning if they have seated properly and if they are actually holding the heatsink down properly.
Ive got a dumb question that i know probaly anyone on here can answer but im a newbie when it comes to overclocking so here goes: What are the key voltages when it comes to overclocking? Cpu Core, Fsb, And northbridge?
and is 1.5 about the most you wanna go before your really pushin it?
and also when it comes to these voltages, the lower you can get all these and still be stable the better?
You know... Big Typhoon with really tightened screws, and a lapped X3350 never went over 55C no matter what. :pQuote:

440Mhz works fine.

Umm... loosen the timings to 5-5-5-15. But sincerely, I got 6GB at 475MHz 4-4-4-12 before. It might not be because you have too much RAM. Try taking two sticks out?Quote:

well, here's to hoping you get a good chip! and enjoy your new card
Thanks. :) At some point, I may just try my luck with another Q9450... or actually, I want to experiment with another one, to see if it was the board... or the chip that was being held back.
My Q9450 is due in the next day or so....god willing i don't get a dud.
Check the VID of the chip. Seems like chips under 1.200v clock really nice!
Well, except from my ubercrappolachip that has 1.125 VID and didn't even manage to be stable at 2.9GHz on stock volts...:shakes:Quote:

Load temp was only 48C on 1.4volts, but still not over 3.2GHz.:ROTF:
If i dropped vcore one notch it failed, and I tried various configs, it scaled terribly bad. Without any doubt the worst chip I've ever tried in 20+ years of hardware experience....taken the expectations in consideration.
It's sold btw, luckily enough I didn't loose much.
Aww... was about to trade with you. No prob, though... as I'm currently busy with some WC setups. :) This time, I'm going to make the ultimate SFF gaming computer!
I got $390 for the chip, I don't think you would've been too happy with it's performance at that price...trust me.;)Quote:

Cool beans man. Keep us posted.
Will do. :) But ONLY if Microcenter rushes my order... gosh... ordered on 04/07/08... shipped on... 04/10/08? What the hell?
http://valid.x86-secret.com/show_oc.php?id=342161
http://i5.photobucket.com/albums/y160/RA1D/4GHz.jpg
currently trying to stabilize this now but it has run a few benchmarks already, no stress tests yet. i'll post voltages when i get it fine tuned.
there may be a fsb hole 490-500 on this board...
Awwweeesome! What kind of voltages do you need for that?
Holy crap, nice results. I should be getting my hands on a q9450 soon, ordered mine back in november :P Never thought I'd be using this e2160 for that long, but it never let me down, allmost saddens me to let this lil fellow go ....
I'm curious how my x38 will hold up with such a beast of a cpu.
WO HOO!...i have an Intel Q9450 in my hands!!
Batch code is L803A550, so thats what...week 3 of 2008?
The IHS seems a bit different to what i have seen before, a slightly revised design.
Anyways just checking in before shutting down and pulling the rig apart....se y'all in a couple of days!
500 FSB is going to be the max for this chip. It doesn't respond well to FSB speeds too far away from it's native 1333. You will see that 3.8 is going to be the limit. ....on air at least. I couldn't get mine absolutely stabile at 3.8 but chips will vary. 3.6 was the best.
Actually, 4.0GHz (500MHz) is possible on air... assuming the board is "electronically" solid. If you can cool your NB with 1.75v of voltage running through it, you're good at 4.0GHz for a year at least.
I'd be curious to know how much vcore is being used for the 4.0GHz too.
I'd guess 1.36-1.38v... or at most 1.40v. :)
I just setup my new system with a lot of help from RunawayPrisoner. Reached my 3DMark 06 goal of 16000.
Just got my 9450 today.
http://mattls.com/hardware/q9450.jpg
Will be putting it underwater later this afternoon.
I do have one question, I've just changed from a q6600, ambient (17°) and stock cooling would idle at 30°, load at 65°. This q9450 at the same ambient will idle at ~40° in RealTemp and load at ~65°. This doesn't seem right. I've mounted it a few times to make sure it was a decent mount. Does anyone else have any idle + load stock temps?
http://mattls.com/hardware/RealTemp.jpg
Q9450 - a 10% better speed over a Q6600 for 160 dollars more than a Q6600. "Doesn't seem right.":rofl:
I just don't think most people will be able to get it prime stabile. That's a really high FSB for one and the chip isn't going to do well that far from it's 1333 FSB. It's a real stretch.Quote:

Nezzari: everything seems okay... aside from some temps. I'm guessing that the 9800GTX adds a lot of heat into the case? If so... please remove that dust filter in the rear fan. It'll help drastically. :) If that doesn't even help, switch the rear fan to exhaust, and switch the two front fans to intake.
CPU installed, i got 3.4GHz with default Vcore...but can someone check it's correct :confused:
Gigabyte X38-DQ6 rev 1.0 with F9a beta bios, the default Vcore is set at 1.23750V....is that correct?
Look at my temps and what not, i haven't tested for stability as yet but i did a fresh install of Vista running at this speed.
What do you mean by "check if it's correct"? Taking EIST into account, the speed you've got showing in CPU-Z is correct for a 3.4GHz speed; not sure if this was your question though.Quote:

Never do that. Always install your OS at default clocks unless you're 100% certain that your OC is stable - and even then I'd still recommend dropping the clock back down. Borking an OS install is comparatively easy, and can be one of the most frustrating and difficult to isolate problems with any rig. Far better off to let it take an extra five minutes now then muck about with reinstalls later.Quote:

Also, your Core Three is looking odd in terms of temps. How's your mount?
Not sure about the core 3 temps, it might take awhile for the AS5 to spread out and the paste to do it's thing.

Do some stress tests with OCCT or Prime95 and see if that clock is stable at 1.12v. An OC should still be fairly stable if you can install Windows with it.
I mean... heck, I installed both Windows XP and Vista at 3.80GHz. :p
Rig in sig...
P04 Bios
3.4Ghz @ 1.23v idle/load, 1.25 bios (havent tried less honestly) Prime stable 8+ hours.
Coretemp VID shows 1.12.
Real temp shows 35/33/33/35 idle and 55/53/53/55 Prime after 1 hour (70F ambient).
What is with my GTLref on this board??? Auto settings have one of them at +45mv for no reason? I set them all to 00mv manually.. What gives there?
480 FSB on P5E3 Premium :D :
http://i90.photobucket.com/albums/k2...Q9450FSB-1.jpg
I am a bit worried about my temps... The OC is stable but that 9800GTX is really making the case hot... How dangerus us 60C load?
http://www.picgarage.net/images/HighT_97038_169.jpeg
Heres mine.
Anything higher, no amount of vcore will get it to boot. I've only set vcore manually, all other voltages are auto. After having a look here, I might try tomorrow with some more voltages discussed, VTT, PLL.
Temps pictured are load, ambient 20°. Idle is ~35°.

Hi any one tried q9450 on a P965 motherboard because I have a ASUS Commando board and just ordered Q9450 I hope it will arrive tomorrow? :confused:
I’m hoping to reach 450FSB any ideas what setting I should use in BIOS ? ;)
1st boot, testing... (1.34v full 1.36v iddle)
I will try this out this weekend.Quote:

In any case - I really want to get it stable at @3.4 (425x8) with 8GB RAM @4-4-4-12 :rolleyes:.
One question would be - how much voltage do you guys think is safe for 24/7 use for x48 and good active cooling? (I've heared that it really should be running below 70°C... and also - that above 1.7v some people said it began degrading - and seems like safe is ~1.65v)
Any other voltages ideas in my case?
When you apply AS5 "spread it" around yourself. I use a plastic baggie (like a sandwich bag) over my finger and put the small dot of AS5 (the size of a grain of rice) in the center of the IHS and then spread it around with my finger tip (covered in plastic) and it works very well.Quote:

I never spread it around. i just put a little dab in the middle of the processor and mount my HSF.:up: I figure its gonna get spread around like as soon as you mount your HSF anyway just like you mentioned. An I've never had a problem Using this method an temps have always been under control.Quote:

Just got the CPU! L803B462 this time guys. :)
Time to get to work!
some new results for overclocking with 8GB of RAM
RP, I followed your advice and also checked out some forums. Indeed - loosening the timings helps a lot.
Running RAM @450MHZ 1:1 5-5-5-18 timings allowed me to overclock much higher. Currently q9450 @3.6; tRD = 8.
Voltages in bios: vcore 1.3, CPU PLL 1.56, NB 1.55, DRAM 2.02, FSB Termination 1.4.
Setting NB to 1.51 --> 1 core in Prime95 fails within 5 minutes. However NB@1.55v is also not completely stable, since one core errored after 56min of prime.
Using 1.55v for NB results in 56°C for NB max during benching (I've read that it should not exceed 60-65°C - apparently came from intel employee). It might be however, that there is simply not enough vcore (didnt try higher then 1.3 yet). In any case - will lapp cpu first. Also - will try to drop the voltages were it is possible. Seems like 3.6 will become my 24/7 speed.
Overall, I am very happy with numbers. :)
http://img138.imageshack.us/img138/4...oredot5.th.jpg
Haha... good numbers. :) I will post some results of the world's sixth 480 FSB stable Q9450 shortly!
my chip is stable at 475fsb with small fft's 1.39v, im sure 480 wont be a problem if the board can handle it.Quote:

So what motherboard do you guys think so far is going to be the best at overclocking this 45nm quad? I'm debating on ordering one of the new x48 chipset boards from either Asus or DFI. I'm hearing mixed reports about quad overclocking on the x38/x48 DFI boards though. I have an Asus P35 P5k Deluxe right now that I will try my q9450 out in first as soon as my new PSU gets here.
Which version of realtemp is best for measuring the temp on the q9450?

Got my new chip in today. New motherboard. New RAM, new... everything! And... I just got that. :D

I could do that kind of overclock with almost all BIOSes... so I'm not sure if it's a BIOS issue. It might actually be the board.
OCCT passed the (1h) test, but then i noticed issues i also had with my old E6600 chip, FSB limitations....i needed to increase FSB and MCH voltages for the PC to boot, not the CPU side but the FSB side.
If I had a X38-DQ6 board, I might be able to mod it for even higher MCH/FSB volts... but right now, I have only the ASUS P5E-VM HDMI board, and I can only mod that one board. (Expect an official thread about the board soon)
Oh, and 500MHz requires 1.732v real.
I passed some 11 hours of Prime95 :)
I received a Q9450 L811A506 tray version today. I will use it tonight on my Maximus Formula with bios modded to Rampage 0308 along with a net set of Mushkin PC2-8000 Redline 2x2 GB.
Does anyone have a experience with that batch ?
http://i30.photobucket.com/albums/c3...n/DSCF1431.jpg
I've seen alot of L803 chips...you've got a very recent chip, week 11 of 2008?
Thats like the end of March.
But lets go even deeper - according to the urban ledged about the last two digits on the PCB, he has a #11 chip. In theory, this shoud be a good overclocker..............
6A0111. :p: I bet that that's the bottom line of being "close" to 0! But I tend to not trust urban legends, really. My last chip ended with 96 and my new one ended with 63, and they both went to or above 4GHz. :)
So far, a quick attempt with a Maximus Formula modded to Rampage 0308, I was only able to reach 8x440. 8x450 resulted in DET DRAM or freeze just at OS loading. 8x440 is rock stable overnight with folding and temps is great (everything is watercooled minus my SB, which have a Enzotech low-profile heatsink with a 120mm fan blowing thru).
Can you give me bios settings for that setup. Cause my X3350 really unstable up to 440 x 8 and dont even want to POST at 450 x8 . ThanksQuote:

hey all, first post here. I recently picked up a system with these specs:
9800gtx (ok wasn't a stellar choice I got a good deal)
q9450
msi p7n platinum
coolit freezone cpu cooler (got this for free for a review ^_^)
Anyways, since it's a water cooler, the passive heatpipe doesn't get the job done. It also has 2 different chips so active cooling directly isn't really an option. It's in a CM stacker case, however, and I haven't used the sidepanel 120mm mount.
I can't seem to get past 3.4ghz or so stable, and I'm nervous about cranking the nb voltage because it gets so damn hot you can't even touch the hs. I would a rigged cardboard wind tunnel going straight from a 120mm fan on the case side to the circular heatsink get my problems in order?
Finlay it seems I have stabilized mine at 440FSB - 3400MHz at 1.2750V and NBV 1.51V. I tried 450FSB I booted up Windows just fine but when I launch Prime it freezes :(
I have noticed that my CPU has a stuck thermal sensor my first core temps almost don't change :shrug:
At 100% load with prime my tems are 38-46-54-54
Yes. Mine also stuck at 3.4Ghz. I've tried any voltage, but no go.
I think my MB might be the main problem...
My turn: just got L806B090.Quote:

hey tv addict, what do you mean with stuck sensors? like they are stuck in one temp and not reading them or that you actually stuck two sensors haha?
i also have a q9450, coretemp and hw monitor read that core 0 and 1 are on 39~43 degrees, but core 3 and core 4 are always stuck on 70 degrees ._.', they dont move, always 70. Is this normal? should i return the cpu or keep it?

here i have two screens, with real temp testing the sensors
3.4GHz stable running Prime95 and OCCT...on default Vcore, i tried 3.45 and 3.5GHz and OCCT crashed within 5 minutes, i didn't increase Vcore though...3.4 is fine for me, i dislike raising voltages if i can avoid it.
I'd like to throw some 1200MHz memory into the mix though to really get some performance.
1.0375VID is normal, i have the same VID with C1E and EIST options enabled, overclocking raises the VID 1.1250V.Quote:

Q9450 OEM L806B090 with Rampage Formula Bios 308:
OCCT stable @ 3.8Ghz with 1.325v
Posting @ 4ghz (8 x 500) but Vista will crash and well I don't want to push voltages more just to do a cpuz validate.
Thanks RunAwayPrisoner and all the others who posted their bios settings :clap:
It's about the same settings here, just small differences.
I can post settings, screenshots, ... after more testing if needed.
Water cooling the N/B definitely helped I guess.
PS: still trying to figure out real temperatures
Congrats can you post your settings?
+1... Nothing more enraging than to see those who post about successfully overclocking above the dreaded 3.6 GHz wall without posting the config :(Quote:

I hope we will get an improved Bios for X48 chipset where we can lower the VTT voltage but till then, you should stay at 3.6GHz if you want to keep your CPU for several years.
It is true that applying over 1.45V to a CPU or VTT with 45nm technology can damage your system." (Safe settings for 3.6GHz at the end of this post)
Work in progress:
Done:
-OCCT 2hours stable
-Prime95 stable (better stay at 3.6GHz if you want to run such Folding programs 24/7)
To do:
-Find best RAM timers
Q9450 OEM L806B090 - Asus Rampage bios 0219 or 0308 (same results) - Vista x64 - CPU & N/B water cooled

Wow thanks.
3.8Ghz with little issues...I have a feeling this is my 24/7 sweet spot on this chip. I bet I could pump some volts through it and bench 4Ghz...that or I am missing something. Anyway, enjoy the pic! Settings listed below. :clap:
http://img413.imageshack.us/img413/8...136vdj3.th.jpg
Bios volts - 1.38v
CPUz reports - 1.36v idle, 1.37v load (board vdroop pencil modded)
NB(SPP) volts - 1.45v
SB(MCP) volts - 1.6v
GTLvref volts - +30mv (all 4 settings)
Memory volts - 2.2 (can probably lower this).
Nice settings, guys. :) See? I kept on shouting that it wasn't the chip...
Anyway, gears will arrive here in a few hours... and then I'll see if 4GHz is stable or benchable! :D
Now if we could just figure out the ongoing X38/48 issues!
