Q9450 OC / Temps / Settings

[Hamilton]

After some further tweaking of voltages and GTLs I got this 9450 completely stable at 447x8. Ran OCCT for 2 hours and Prime for 13 hours without any errors.

450x8 would run 3DM06, Cinebench R10, DVD Shrink 3.2 without problems but Prime and OCCT would give errors after 20-30mins.

This was using the following voltages:
Vcore: 1.45V (could probably be lowered a bit more)
Vmem: 2.19V
Vnb: 1.66V
VTT: 1.438V
GTLs: 75 75 80

This was a far as I got with this 9450 before I returned it yesterday.
Unfortunately this CPU was a bit of a dissapointment as it's very limited by FSB and low multi.
If I was spending my own money I think I'd rather go for a E8500 that might hit close to 5GHz with high FSBs.

Now I've got two QX9650s to try out. One week34 ES and one retail week 39!

Just got my Q9450. It's stepping is L811A887.

[Khaotic]

can you post a picture, including the numbers on the PCB.......

[Cob]

Nope. I've only got a camera phone and it can't pick up the codes.

The codes on the PCB are -

2V80713 OR 2V88713

3A0467


I think the 4th digit of the first code is a 0, tho it's possible it's an 8. An 8 would make more sense considering my stepping ends in 887, but the more I look at it the more it appears to be a 0.

Looking good

1.27v at 3.8Ghz egg... nice!

[SoulsCollective]

Just got mine. Will be about two weeks before I can get some hard numbers up, though, waiting on my RAM.

Well, this is very odd... The vdrop on my motherboard seems to be gone... After my mod wore off, I raised the voltage to keep it stable 24/7 (too lazy to redo it.) I just lowered it back down to 1.32V and I seem to be getting real 1.32V on idle and load...

[Cob]

1.27v at 3.8Ghz egg... nice!

It's 1.35v. OCCT can't read the voltages correctly. Everest can tho.

[Cob]

Needed a bit more NB to finally get 3.8ghz stable -

[Unoid]

so 1.30 is a safe 24/7 voltage to last a few years?

I am new to this whole seen and have a question which may seem dumb.
what does vtt stand for. I am lost on most of the acronyms

It's the FSB Voltage Termination.

Upping it helps gain more FSB.

Interesting... would it also help by letting you use a lower Vcore?

[m4gg0t]

i want to get one of these Q9450 but it costs SGD$540+.

Not really.

You bring it into the equation when adding more vcore starts to have little or no effect on its own.

Well i just tried my first overclock, and had to up Vcore quite a few steps to get the cpu stable @ 3.2GHz, but I left everything else alone. So there's no chance I might be able to back it off a bit using vtt (or anything else for that matter) ?

You can try it and see.

Every chip and motherboard is different.

Wow.. I was 1.19v for 3.2Ghz. Everything else on auto...

[Nits]

Yeah - I thought it seemed quite allot!

Thanks guys, I'll give it a go.

Is there anything else that might help me keep a bit of Vcore headroom for a potential 3.4GHz clock?

[Nits]

Not helping much before I start getting into borderline unsafe Vtt values

[Sem]

so whats the verdict with these chips

are most good for 3.6 or am i better off with a Q6600

[jas420221]

3.6-3.8Ghz seems like the sweet spot on air with a solid mobo.

[o0oPhreako0o]

You think I can make 3.6 / 3.8 with this ?

Q9450
Asus P5e3 Premium
OCZ XTC Platinum 1600mhz
Cooler Master 850watt Modular
TRUE (with 2 Coolermaster 43cfm push/pull)
Antec Nine Hundred (fans on medium.. If it matters :P)

I know every mobo/processor is different.. But I would like to
get an indication. As im getting worried

Likely 3.6+...yes.
