What vcore you using for 4Ghz
Going to be overclocking my Q9550 - Is this a good chip?
- Thread starter toon_mad
- Start date
4.2GHZ! VCore shown in cpu-z (theres hardly any vdroop, that vcore is pretty much what i set in bios)
Intel specifies my chip can run upto 1.3625v so i can get a tad more out if needed

Safe depends on your feelings towards load line calibration, the reason you're seeing no vdroop. The board is forcing it against intel spec, but this does let you set a lower vcore in the bios and feel all safe and content. I'd rather a higher bios setting and following intel spec, than a lower bios setting violating it, given that the load voltage is the same in each case anyway,
1.3V is well within sensible limits aside from this, you've got until 1.4V before any stress. I don't know what temperatures you're hitting, and I'm afraid the above benchmark means nothing to me at all. Is it acting as a stability test? If so you've done very well making it to 4.2 so quickly.

Not Stress Tested with Prime95 yet, just needed to check the max safe vcore as im sure it needs bumping right up, those little benchmarks are just so i can find the max (or high) fsb i can run.
Will stress it tomorrow see how i go, i think the most i might goto is 1.38v or something. Will keep you updated

not a good VID I'm thinking.my VID in coretemp is 1.15v
ive had my Q9550 up to 4.4ghz and could get more easily, 4ghz seems stable after hours of testing. Once i know the 4ghz is rock solid, might see how much more voltage it would take to get higher.
currently running at 4.2ghz with some testing, needs a bit tweaking so far, cpu-z reports it a 1.32v in bios its something like 1.34 so slight vdroop.
Also im idling at 40c which i think is good considering the clock speed

I'm still getting a feel for the chip and cooling atm - not used to them with this high a VID.
On stock an hour on OCCT gave 1.24 vcore flatline with 0.02v ripple, max temp was 48C most of the time it was wandering around between 44 and 46C as the fan compensated.

3.825gig 1hour OCCT stable... its a good start... tho as you can see the vcore is terrible (1.3625 set in BIOS)... temps looking reasonable - I can prolly get that down another 5C with a bit of tweaking and once the AS5 has had time to "bed down".
Looks to be about my limit - increasing vcore to the next step takes it to 1.38 actual windows idle... which is getting a bit too close to 1.4+ for my liking... and it wasn't OCCT stable at 4.03gig with that vcore. Taking the VID and motherboard into account 3.8-3.9gig isn't bad going and can always go for the suicide voltages when I'm feeling ready for another upgrade.
EDIT: Forgot I'm not running with the vmod... might be able to eek a little more out with that applied to stabalise the vcore.

Mine is 1.272/1.28 idle windows (for 2.84Ghz)
Not unless P45 boards are better with the vcore on chips.

P45 boards are a LOT better for quad cores than nForce motherboards heh...
I'm quite impressed actually - I thought this was only a minor upgrade from my Q6600 @ 3.6gig but even at 3.825 I'm seeing almost 40% framerate improvements in some 3D/Game benchmarks.

my idle vcore at stock is only 1.010v
i can hit 4ghz stable easy, 4.25ghz the highest i tested needs more work.
ive started from stock again, found some interesting new features like robust graphics booster and ddr3 performance enhance, once these are set will work my way up now i know the fsb has no walls upto 500fsb

RGB just auto overclocks your GPU by 10% I think... and can make a right mess of things.
4ghz stable unfortunatly is gonna need some intensive tweaking on my setup and almost deffinatly the pencil mod to remove vdroop if I want to hit it on "safe" voltages.
On the plus side - hitting 11,300MB/s Memory read speed @ 3.825 and my memory isn't even close to maxed out (1080MHz - these OCZ Blades are good for 1333+ CAS5)

well i played gta iv for 1 hour with the rgb booster on and it was flawless, in fact games error more with it off.
i knew the pencil mod worked with the q6600 but didnt think it would with this chip, must be all skt 775 processors then.

You can shade a resistor on the board I have to almost completely remove vdrop and massively reduce droop. With the Q6600 it was the only way to get above ~3gig but not sure what affect it would have with the Q9550 so I erased it before I put the CPU in.
Thats pretty much what I'm thinking... when it starts getting a bit long in the tooth I might pump the voltage up and see how long it lasts beyond 4gig... its already more CPU power than even my overclocked 260GTX SLI setup can deal with... tho that might change when I have a GT300 or 2 to play with.
