Q9450 OC / Temps / Settings

[Loser777]

It will cost more, but I picked up mine from Fry's. If you have one near you and can afford the time & money, I'd grab 2 or 3. I picked up two and will try 'em both to get 500FSB with good volts. If they don't I'll take em back and try another. So far I'e got one that tops out at 498FSB with the northbridge maxed. Holding on to it till I get one better. Yes I know this is a dirty game but heck someone else gets to buy the pretested board for 10-15% less.

I have a Fry's close by too...
What is the level variance for max FSB on these boards? Is is it really that bad?

Do you know what the current price @ Fry's is? $130 on newegg.

From what I've seen the FSB's are all about the same, its the amount of volts required to acheive them that differs. If you can hit say 450 on auto, then chances are you can hit 500 @ the max of 1.71V. Runawayprisoner has had more than one and refers to some requiring more volts than others @ certain speeds. I too want 450-475FSB with low volts for 24/7 operation and don't care what volts it takes 495+ as long as it will. If you need the full 1.71v just to get 475 stable then 500 won't be likely. Once I find one that can hit 450 on auto and +500 @1.71v then I'm gonna keep it and change the northbridge cooling. They're $154 here in Texas. I've only tried one thus far, the next one will be tried this weekend.

What do you suggest for NB? I was thinking of simply adding a cheap 40mm fan...
I'd be fine with basically any board that gets 475 on air... The problem is that I'm not sure about my RAM...
It's running at 916MHz 6-6-6-18... I can't test higher so that could always be a limit... Plus it's heatspreaderless so I'm worried giving it more than 1.9v.

[EJTREM3]

OK, different batch, but for your reference, the 3 dogs I had came from L806AXXX. Again all of these chips displayed the same issues you're experiencing. Some are saying the sensors on the Q9450 are faulty. Take that with a grain of salt. I still don't recommend trying to push these chips even under water with these wacked out temps.

umm i see thx 4 the trip.
i going see if sell this chip

The Thermaltake Extreme Spirit II has been proven by runawayprisoner so that's what I had picked up.

My P5K-DLX kicked the can earlier today running same settings its been running 24/7 for nearly 2 weeks.

Hope it didnt take my X3350 with it

All I have for a backup board is an Asrock 775Dual-VSTA. X3350 wont post on it

[DjLeco]

That's my Q9450, mounted on Gigabyte EX38-DQ6, cooled by Scythe Zipang.

Vcore setup in bios 1,3125.

V Fsb +0,20 volts.

V Nb +0,20 volts.

V Dram +0.20 volts.

Memory 4x1Gb Crucial BallistiX Tracer with Led latency 4.4.4.12 @ 900 Mhz (1/1 Dram/Fsb)

Look's it have a FSB wall around 460 mhz, I will try more, with more voltage on Vfsb and VNb later
Enjoy it.

A question, CoreTemp V 098.B1 shows 1,0875 VID, and Coretemp 099 shows 1,20 VID, wich is real?

[NIZ]

Anyone tried the new P45 chipset with their chips yet? Any improvement?

There are quite a few people on the thread about the new ASUS P5Q Deluxe board. Go here: http://www.xtremesystems.org/forums/...d.php?t=189437

There is a broad range of CPUs being used on it, quads and duos alike.

[LUCI5R]

My P45 (ASUS P5Q Deluxe) is arriving Tuesday. I got this Q9450 last week - I'll be setting everything up & OC'ing by the end of next week.

Okay My first P5E-VM HDMI(pencil vdrooped) may be a keeper unless I find one that breaks 500FSB with 45nm Quad.

Any opinion?

[Jupiler]

The second reading is correct, so 1.200V.
You can also use realtemp to check the VID of your cpu.

[Aequitus]

Nemesis, is it safe to leave the motherboard voltage settings on auto?
I was under the impression that the boards can over compensate, over-volting some components unnecassarily?

Thank You.
1,200 is a good VID for Q9450?

Is GOOD O/C 3600 Mhz for 1,26x Vcore on LOAD on AIR?

[AquaRelliux]

Thank You.

It is pretty decent not the worst but not the best either, I have 1.1750 vid and mine can do 3600mhz on 1.216v load

I haven't had any bad expirences with auto. It typically would set voltages too low and I would have to manually set them higher to get stable. Only the VTT & North Bridge voltages need increasing on this board as you go up in FSB. The PLL seems to overvolt regardless of what you set. 1.52v showed 1.6v+ in windows.

I have two Xeons X3350 with the same WK/batch. One of them has the vid of 1.2V and the second one 1.2375. The second one clocks a bit better and is also a bit cooler. vid itself doesn't matter in terms of the CPU's overclockability. If it did, then QX9770 would be the worst clocker as it has the highest vid in most cases (1.275V in my case). So just OC and you'll see what your babe is able to do.

[QettoE]

Question that might not be related much, but look at my 5v:



System is running stable like a rock. I wonder if the reading is wrong. Would even a system run alright with such low 5v rail?

The VID on my Q9550 was at 1.1625 but after a couple of weeks of testing, tweaking, priming it has jumped up to 1.2375 , which is higher than my Q6600 VID 1.225.

hey guys, just booted my q9450 @ 3.8

heres what im using

Asus P5E-VM HDMI, 2x 1GB Crucial Ballistix DDR2 800, q9450

this is what concerns me, the 4th core temp sensor doesnt
work.. i havent reseat the CPU yet, since i just installed
everything, so ill try that tomorrow but it concerns me much

has anyone ever have this issue? and can it be fixed

i know this doesnt belong here but seems like when i change
some things in the bios it doesnt directly apply.. like my ram
speed and timing are manually set but seem to be automatically
set when booted..

thanks in advanced

[mustrum]

Can you get it stable? I can boot my xeon 3350 at 3.7 just fine with extreme voltage on the NB. I can`t get it to prime for more then a few minutes before freezing though. Stable easily on a P35 board of my mate though. (And more then 3.7 actually) Booting doesn`t say much when it crashes all the time.

[JeffLo]

just got a q9450 but i think my temps are stuck on core's 3 and 4 should i return this cpu? and idle or load temps on core 3 and 4 always have the same temp its kinda bugging me if i have a diffective proc, any suggestion or info? and what safe temps should i have for a 24/7 setup idle and load?

core temp 0.99

--idle--
core #0 52c
core #1 49c
core #2 65c
core #3 65c

--load--
core #0 66c
core #1 62c
core #2 71c
core #3 71c

Real Temp 2.5

--idle--
core #0 42c
core #1 39c
core #2 54c
core #3 54c

--load--
core #0 57c
