    what do u mean unable?

    i got mine to 545/1.25

    what it is, is a heating issue because overclocking means more heat and if your using the factory heatsink/fan you arnt going any higher

    also when using fans your computer can only get as cool as room temp thats why fan cooling isnt to great

    I've got a PNY 6600 GT, on the stock heat sink with a 80mm fan pulling hot air out right on top and a pci slot open for air intake, I'm getting stable at about 530. Is this becuase it's a PNY or the cooling? anyone else have a PNY?

    how are you guys testing for stability?
    I used Lock-on and Pacific fighters.

    With Lock-on, I'll notice purple / green random patches of area showing up. At the same speed, with PF, I don't get noticible color patches but i've noticed that it freezes more frequently. It usually takes about 5 sec before it unfreezes.


    as for the card itself, is it made by Nvidia and just slapped on a PNY sticker or did PNY actually make the card?

    is the problem really heat sink related?

    I also have a PNY and it clocks to about 555 core before I see artifacts, I believe its the crappy cooling PNY gives.

    Well it is deffently a heating issue
    as when you up the clock speeds more heat is produced and stock fans do an ok job at normal speeds but with all the extra heat it wont help much

    if you where get peal that fan off and but some AS5 and maybe a new heatsink im guessing you would see a 5-10 degree drop maybe

    those purple and green random areas arnt good just leave your card set to default to prevent any damage because overclocking is not covered under warentee

    and plus the 6600GT can handle any game out i know because i have one

    also PNY makes the card, NVIDIA send them a reference card that they made plus the info on it and PNY makes them

    I dont think its the card holding you back as much as the heat

    also did you get your processor from 2.4 to 3.19 on stock cooling?

    Sounds like a heat problem as some ofthe heatsinks some of the manufacturers put on the cards are too small compared to the reference design. Your memory probably won't go any higher as its probably the slower 2.0ns compared to the 1.6ns used on some of the cards, although I would have thought you coudl have pushed it higher than what you have got it. Try a aftermarket cooler from Artic cooling (if they make a silencer to fit) or the Zalman cooler and make sure with the latter that you run little memory sinks as well.

    Without artefacts? As far as the video card is heated up during tests?

    I may have used a stock intel sink for hte 3.0 cpu. it's not the straight fin heat sink. The fins are slightly curved in a slight circular. But no, it's not after market.

    some how I missed part of the reply in the last post. If I replace the heat sink / fan, that voids the warranty right? I'm debating if I should or not....just for the warranty. Although, by flashing hte temp sensor mod, I guess I already did that.
    If i flash back the original bios, will they be able to tell that the "original" bios was overwritten? does the flash process record a date/time?

    I guess i should run it at stock and see if there is anything wrong iwth the card....

    I tried to find some comparisons on what heat sink to get....but didn't see anything targeting 6600GT. Anyone seen something like that?

    as for my cpu oc....I was actually hoping to get more... :D
    I think my ram may not be able to handle it.
    look here:

    don't know how to interpret the numbers.... but I was wrong in my memory. the fins aren't ciruclar but just slanted. This is different than the straight slotted type.

    here's how my air flow is. Prior to getting the GT last week, I did not have the 2 side fans (I know they look ugly....it was a rushed job, plus I don't have the right tools.) and no open pci slot/ drive bay. There is a hidding fan in the lower front corner blowing air in.

    after the GT, I noticed temp seemed high so I added those.
