Q9450 OC / Temps / Settings

[trt740]

That seems to be the problem with these quad 45nm chips. The need for relatively low vcore (mine needed 1.298 to be 3.6GHz P95 small ffts) but a ton of NB and VTT to get it blend stable.

is vtt the same as PLL

[trt740]

is vtt the same as PLL

also I'm testing a q9450 that is supposed to do 3.88ghz

[Shadowthor]

vtt is know on some mobos as FSB Termination Voltage. PLL is completely different from vtt. On 45nm, vtt shouldn't exceed 1.4 as it will cause electromigration (cause the chip to slowly die).

Fixed!

L812B258, Pack Date 05/15/08 should be avoided, has a VID=1.25

[JeffLo]

hello which is better for the q9450

Gigabyte X48-DQ6 or abit ip35-pro?

Probably the abit if it has a P35 chipset and has the bios options you need.
The x48 chipset does not work well with 45nm quads.

Thats not entirely true. I have the Rampage Formula (X48 Chipset) and have the Q9450 overclock to 3.6ghz. The X48 supports 45nm quads natively, unlike the P35 chipset where you have to upgrade the bios.

This is my new toy:



Vid, according to coretemp, 1,25.

Vnb 1,29 volt, vtt 1,2 volt, fsb 1,6 volt.

It's an L815 boxed.

I've tested two of them and they clock exactly the same.

my p5k deluxe is not native 45nm, bios 0812. sorry bout the zis of the pic, i fondy know how to get a smaller size

[Nano74]

All test with Thermaltake Max Orb, AC5, is not the best cooler but for my quad is enough.
Temps in full load 63-64-55-65 at 3,8ghz


Later i will test more than 3,8ghz if i can do it.

Asus Rampage Formula x48
4x2GB G.Skill PC2 8000 (DDR2 1000)

Edit: I over-volted cpu vcore because I was experimenting with LLC for stability as there have been reports about instability on the RF.

[Nano74]

oh yeaah i see too much v core in your quad, , re u using watercooling right??, but i see x48 is much better, if i put 3,91ghz like u my score in cinebench will be lower for sure, pretty nice chiset Zucker2k.
Iv been tested at 3,9ghz and i boot fine but my temps re a little hi, , almost 57 in cpu adn cores right 58 avg, but if y bench, ohh my god there s a barbaque here, all invited jajajajaaj

Nice clocks yourself Nano74; my temps are crazy high, i got stuck temps.

[ChaosMinionX]

Looks like I just need to buy a real Rampage, and get a new Q9450...

Good results Zucker.

tnxs Zucker!, buy x48 is really superior, look at cinebench to much diference thats te good of your mobo, , exceleent performance.!

Plz can u post at 3,8ghz to compare in evereest test ans super pi. I can see the difference between x48 and p35 chipsets, obviously if u want!

Tnxs again men!!

Your welcome.... here is cinebench at 3.8Ghz... I posted this result here http://www.xtremesystems.org/forums/...=156129&page=3 last week. I'll run a 32m pi now and post results asap.

Thought I'd have a last play with this chip in the IP35 Pro before I start playing with the P5Q Deluxe -





Not bad considering the VTT only goes upto 1.42v in this board.

Anyone running this chip in the P5Q Deluxe motherboard? I've got the following recommended BIOS settings for that board. I'd like to hit as close to 500FSB as my 'on air' setup can possibly take.

we want to see that extreme oc!!!!!

[jadeiceman]

Hi, I'm new to overclocking, and I just got a Q9450. I got it to 3.2Ghz by only changing the vcore to 1.26 and everything else on auto, but after 2 hours of prime95, Realtemp reads that the max temps were 65, 53, 56, 60c. According to my thermometer, it's about 88 degrees in my room. I have a TRUE 120 and an EVGA 780i mobo. Are these temps too high? Do I need to remount the HS? or just try lowering the vcore? What's a good amount of time to run prime95 for ? Sorry for all these questions. I searched around and I'm still a little uncertain.

[jas420221]

Those temps arent bad for air coooling in a 88F room. 65C is the max I would go so you are fine.

Welcome BTW!

[jadeiceman]

Wow thanks! What a quick reply!

[jadeiceman]

Uh oh, I just found out that I read the thermometer wrong. It's actually 78*F. Are my temps still ok?
