Q9450 OCing Question - Page 3

post #21 of 51
buxboy your chip has great potential, you're still on stock voltage! You can safely go up to 1.3625, so get started!

On a side note, sorry to be harsh, but quite frankly the people saying the Q9450 is a terrible buy and sucks for overclocking and is fsb limited are idiots. You've never tried it for yourself, most people don't know HOW to overclock it.

I will be posting my results either on the 8th or the 9th. My motherboard has been proven to do close to 600MHz fsb with the stock nb cooler with a dual. I will have a thermalright HR-05 IFX with an 80mm fan on it, and an HR-09 on the mosfets with a 40mm fan. And the board has no vdroop. Look out, I have a feeling I am in for some great overclocking

Oh, and the P35 chipset can do MUCH higher FSB than x38 and x48.

I have to say I am proving a lot of nay sayers wrong, even with only my first day of OCing under my belt. My mobo may not have been the best choice for this CPU, but frankly it is working just fine right now and I love the other features taht came with it.

Like I said, I am shooting for as far as I can go, hoping for at stability at 3.8. Then, I will most likely keep it at 3.6 24/7.

VTT: 1.55v
MCH: 1.65v
vdimm: 2.2v

Any higher than a 450 fsb requires much higher VTT and MCH voltages for me to even get into windows. I tried a 455 fsb but can't seem to get it stable.
Do you have any exact numbers on how high those voltages were to be stable over 450?

I'm assuming your hinting this a little at me with what I said about the FSB being a limiting factor.

I am saying what I said because I HAVE tried it myself. the x3350 that I have is the same as the q9450 just rebadged xeon instead.

with what I have seen from others as well as my own experience I will still stick to what I said with he will be motherboard limited. first thing with that is quads put a lot more stress on the mobo. I can attest to that easily as I came from a e6600 to a q9450. with the e6600 I was able to get the computer to post at around 490mhz FSB. with the quad I'm lucky to get it to even post at around 470-480ish so far I have not been able to get it stable much past 450-460mhz. this is even when trying to do a suicidish style run with most every option set to max as well as cpu voltage set at little over 1.4v in the bios. even if I drop the multi down to x6 it still refuses to go higher and to me that sounds like it is a mobo limit not a cpu limit.


now with you saying your board can do 600mhz FSB bus that is great. can you show me where someone did that with a quad? chances are you won't without finding them doing some mods to the board if you can even find one doing that. if you believe your board will even get close to that with your current chip I believe your going to be in for a disapointing result. don't get me wrong I wish you the best with this but I will still stand by what I said with motherboard being the limit unless you can show me otherwise.

I am having severe trouble breaking 3.49 ghz.

Nothing I do seems to help at all.

By the way, since I am so used to AMD OCing, I am wondering if the PCI freq makes a difference. I know with my AMD Athlon 4000+ raising it from 100 to 108 made a difference with overclocking. Can anyone tell me if this is true with intel aswell?

Actually I wasn't hinting at you.

I don't expect to hit 600MHZ fsb! I said that was with a DUAL core. I am hoping for 475, maybe 500 if I'm lucky.

probably not, whole other animal.

I must say, rx7 and 003, you guys are both right, you can't fault the cpu because of the low multiplier, and you can't blame the mobo when you can't crank the fsb as high with a quad, thats just how it is, every mobo does it, youll see 003. But you cant say people are wrong because your mobo can do it, not everyone has your mobo, plus it looks like youre not using stock cooling, people have gotten past 500 with the 780i with aftermarket cooling.

some report it seems to help on the bleeding edge but also it can cause issues with the hard drives either not being reported or causing some file corruption. myself I haven't noticed much of a difference but yet I still run mine at around 110mhz.


just curious how do you have everything setup in the bios?



003 ok so you did say dual and I just can't read.

Well what do you suggest? That I run it at 100 or crank it up?

When you are asking about my bios, are you asking about my voltages or what?

Here's what's going on in the bios:
FSB Freq: 436
PCIE Freq: 110
vcore: 1.24
MCH: 1.73
vdimm: 2.20
VTT: 1.60


It seems to be stable at this. It won't remain stable at 3.5 for any long length of time.



Have I reached the top end? Are these voltages safe? Should I push it more tomorrow when I resume my trials or is this as far as I can get?
