Vista - CPU OC Wall?

SOrry for the Double Post, but the board only allows for so many quotations per post....

loco - first off you'll need to decide whether you can live with high temps or not - either you have a very poor cooler, or it was poorly installed. I haven't seen temps like yours with my OCed system *at full use* - In fact, I've never see 55 deg C yet....

As for my mobo being better to OC, according to Fumz, it ain't so good - DFI seems to be the way to go in terms of true OC-ability, but I picked this as a nice balance between enthusiast and run of the mill generic boards.

I might look into another machine in a year (I've been bitten by the bug, I want to build a truly powerful rig this time - hopefully for under $3000 USD)

Great point about the misconception that Water cooling *automatically* allows for better overclocking, unless, of course, it has to do with the Northbridge cooling - that is one of the hottest places on the planet, net to my GPU under load, and I am pretty sure that with a bit of better cooling I think I might be able to break the wall.

I am guessing that even at 3.6 GHz my CPU will not be trying to drain the system of above 1.5 V, but this is theory on my part, based upon the MCP cooling issue these boards have.

And, you're right, Fumz, I should actually be quite happy with a 33%OC, back in the day 15% was astounding, until Intel started binning CPUs heavily.

I can live with that heat. I'm using an el cheapo Rosewill cooler and I've reseated 4-5 times cleaning off and reapplying the TP each time. While the idle temps are high, under full load they rarely go over 60C. I keep the A/C on 72F, but the PC is in the loft and it's usually 5-6 degrees hotter there as far as ambient temps go. Unless I get a new cooler I doubt I'll see anything much lower.

You can live with the temps - now - but as soon as you OC they'll go up....hence my point.

There is no fan attatched to that Tuniq is there?

Picasa Web Albums - johnlgalt - The Beast

That thing is a monster isn't it.....never mind I found the midship fan ( Tuniq - Tower 120 Cooler).

EDIT: If you want to go for that Scythe/TRUE120 cooler combo, I'll take the Tuniq off your hand for a fair price.

The fan is inside the heatsink... smack dab in the middle.

lol loco - I was looking to replace the fan part only.

That Tuniq is a beast, but for under $50 USD I can't complain at its sheer cooling power for an Air cooler.

hey fumz...

isn't it amazing how far the clocks can go when the chip is kept cool....
yes its LN2 but he is probably pushing 2.0v vcore through a 45nm chip to get that
so i still stand by the fact that heat plays a bigger part than volts


Andre Yang, a civil engineer doing his PhD. in the US obtained a high-performing Core 2 Duo E8600 processor, he succeeded in overclocking this chip to a stellar 6.70 GHz clock-speed (FSB 672.16 x 10.0). The processor uses liquid-nitrogen (LN2) cooling and surprisingly this processor was overclocked on a motherboard with the Intel X48 chipset, the ASUS Rampage Extreme when previous record-holders across several recent processors made use of either the Intel P35 or P45-based motherboards.

john .....that is still a sweet OC & i was not suggesting you buy a WC setup ....i was merely stating i think you hit your limit on air.

I know you weren't, skunk

lol...

Nobody argued heat wasn't a factor, it's just not a factor here. It's also true that as you increase vcore heat rises exponentially. Nobody said anything different; but again, heat's not really the issue here as johngalt's temps are well below 70C.

It's also true that you can get some insane sub-zero clocks as you're able to pump tons of volts into the core and keep the cpu cool enough to operate. However, electromigration occurs no matter what. It's brought on first and formost by volts. Heat exacerbates the problem, but it's still the volts that kill cpus. It really doesn't matter how cool you're able to keep a chip, over-volting is going to kill it.

Nobody runs LN 24/7. Chips just don't last that long under that kind of voltage. While it's a neat feat, it's wholly unrealistic as an option for the normal user. Watercooling comes nowhere near phase or LN. As it applies here, since we're already talking about a vcore of 1.45, it's really not worth the cost. He'll maybe shave 5C off his current temps, which are already very low given the voltage.

ok i think its fair to assume both points have merit.......
i DO NOT believe he should buy a WC setup to further his OC
but i do think there is only so far you can go on air......

would you not agree...?

i still believe that in ''domestic systems'' heat is still more of a factor than volts as electromigration will take far longer to have an effect than say someone with a 40c ambient resulting in a 50 or 60c idle...(its just an example)
