overclocking Q9550 past 450FSB


Recommended Posts

hello guys..

 

I got my Q9550 yesterday I already got it to over clock but I can't get it past 450FSB

 

my voltage look like this 1.225 cpu core

cpll @1.65volts

FSB term 1.4

northbridge is at 1.65 volts

these are what I feel safe with

 

my memery is set for 1153 but I can't get it to 1199.

 

my system specs in full

4Gb OCZ reapers 5-5-5-15 @2.2 1066

3 SATA2 HDDs one 500GB seaage 2 250Gb seagates

two optical drives

1100wat ABS LABS/tagan

CPU heatsink OCZ venetta 2 (I some how mounted it properly this time :O)

2*HD4870 512 sapphire one with toxic ref cooler on

I would like to see it go past the 450 mark I think its memroy that holds me back, but not sure

What exactly is failing? You're overclocking your memory at your current settings, the first thing I'd do is run them 1:1 to get a 900 MHz memory clock.

 

Past that, higher NB voltage or possibly more vcore depending on what kind of tests are failing. Your vcore is pretty low for that speed, it'd be the first thing I'd raise after changing the memory frequency.

 

 

I'd suggest using IntelBurnTest to check for stability and temperatures as well, it's by far the fastest and hottest way to test.

I agree with Waco, drop the memory to 900MHz and then OC the CPU from there. there's no point in testing your CPU overclock if you don't know if your RAM is stable. btw, my Q9550 won't get stable over 450MHz FSB. I've bumped vcore to 1.425v and run NB voltage to 1.5v and it still doesn't get stable. You may just have reached as high as that chip'll go.

okays Ill try that see whats what

 

I found a setting were it seems happy 444FSB with the memery at about 1153 with the voltages I posted.

 

I was wondering if there is any life left my OEM Q9550...thats another reason why I don't want to blow it cos its expensive and I have no "protection" like I did with my old Q6600 which was garenteed chip.

 

as for memery is it posible to get it up to 1200? OCZ reapers 1066 5-5-5-15 4Gb btw

1.65 volts on NB and folks are saying to add more?

 

As for your RAM, I would agree with running It at 900. Even if you could get your sticks to run at 1200(I highly doubt they will) it wouldn't be noticeable.

Hmm... Sad to hear. I have my Q9450 humming along at 3.6GHz at 450 FSB. I've had it up to 460 FSB, but backed off due to heat. O, it's 1.296V too. Seems like your Q9550 should go higher than it is, maybe you just got a junk chip?

Yeah I heard the newer Q9550 have a lower wall and don't oc as high as the good old Q9450. If your ram isn't limiting you, it just may be your wall. Mine does 4 ghz max, anything over 500 fsb, even 501 doesn't even boot even with 1.8 vcore.

err I tried 500 just to make sure it was not mobo and it wouldn't boot it got stuck on the detDRAM no matter what I did to it

 

I think you should know my Q9550 is a OEM but than i was told there is no difference its spec was identical to the retil version

 

does boot at 460 but I can't get into windows or liunx

I think it does..is that the voltage multiple thing?

 

 

 

I don't consider it as a bad overclock considering its OEM and stuff, I don't really want to give this one too much and degrade it like what happened last time >>.>> but that was a powersupply shorting out :P

It sounds like you're just setting random settings and hoping for the best...

 

Dropping that RAM multiplier should be your first step. There's no reason to stress the RAM or memory controller when you aren't even sure the CPU is stable.

 

1.65 volts on NB and folks are saying to add more?

:blink: I didn't even see that. That's probably too much voltage and that could be hurting things as well. Isn't stock for his board something like 1.3 volts?

stop messing about with only 1.225v @ 3.6 GHz and give the CPU at least 1.325v... I'd use 1.35-1.4v on decent air...

 

put the RAM at 1:2 ratio for DDR900 until you've figured out the CPU OC... don't even think about the RAM until you've maxed the CPU... and there's no way you can OC the CPU fully with only 1.225v
