Ivy Bridge 3570K Testing, Opinions, Results, New Bios, 4.5Ghz At 1.236v

rge2: Thank you for one of the most informative and interesting cooling posts I've read online.

I just read through all 24 pages of this thread, and I have to say YOU ARE ALL SPOILED BRATS!! Screw ALL of you with your 5ghz SBs!!!one My 2600k tops out at 4.4ghz @ 1.345 w/HT, 4.5ghz @ 1.34 w/o HT... I for one welcome our new intel overlords and can't WAIT to replace this hunker with an efficient 4.5ghz IB o/c. (My son is getting my SB, or else I wouldn't bother )

My sentiments exactly, I think a lot of people wrongly assume that "most" SB chips will clock up to 4.8-5ghz will 1.3v lol.

My 2500k certainly gets nowhere near this, hell I can barely push 4.4 on what some people are claiming to be 5ghz 24/7 stable on. From what I can tell my numbers are a hell of a lot closer to the "average" chip than these golden chips.

rge, that kind of makes sense. Thermal paste is very resistive, and could really centralize the hot spot (where the CPU chip is). But the IHS would allow the heat to spread out laterally before moving upward.

Yes resistance goes up with the IHS, but resistance per unit area is the key thing here. You're all thinking about linear resistance. Basically, it might be easier to push 100W through IHS -> TIM -> Heatsink over a 1in^2 area than it is to push 100W through TIM -> Heatsink over an area a fourth that size.

All the results I've seen after delidding have been rather lack luster, a few C difference at best, sometimes no difference or even higher temps.

If you want lower temps, get a better cooling solution, or fix your H80 *cough*

I actually hope Ivy runs a bit hotter and custom loops give back 300-500Mhz over air, gives people who invest in their systems a return...

 

[HilbertSpace]

Some points to also consider are that heat transfer is not just dependent on thermal conductivity values for materials. There are many other factors that come into play, namely temperature differential, and also clamping pressure of the heatsink to the IHS or die.

@talonz, thanks

@njdevilsfan87, yep, exactly.

But I am all for direct die cooling without user tim interface, I would love to convince intel to sell their cpu dies solder attached to high end waterblocks, but just wishful impractical thinking on my part.

Has anyone seen a Z77 with a NF200 yet? I'm still leaning towards a 3820 since it has massive upgradability and IB is a dead end. I figure an extra $75 is a steal for the superior x79 platform. If I can get the extra lanes for IB it might be worth getting one. I only upgrade CPU/mobo every 3 years and IB's PCIe will be begging for mercy before then.

So with a H100 what would you guestimate the max oc on a 3770k?

The NF200 is basically a gimmick to get you the additional pcie sockets on a limited platform like the mainstream SB/IB. It's impossible to add any more pcie lanes into the CPU than what the CPU is capable of, but it does add more bandwidth between the video cards on the bus. The problem is that it also introduces more latency.

Get an X79 platform / 3820 and forget Z77 w/nf200.

4750mhz linx, 4800 prime, 4900 games, 5100 cinebench, 5200 pi

I'm pretty sure that the Asus P8Z77-WS has a bridge chip of some sort. I don't know if it's an NF200 though.

Like Grooveriding said, If you really need more PCIe lanes, then you should be considering the X79 platform.

Hey Don, I didn't see a mention anywhere, but is any amount of BLCK (or whatever it's called now) overclocking possible? I know with Sandy, you wouldn't get much past 105Mhz BCLK, so the only realistic way to overclock was via multiplier.

I remember there being some rumors that Ivy would have some modest wiggle room with BCLK.

Honestly bro i haven't even attempted it. It was rumored to have 133bclk or something of that nature but i haven't even attempted it. In the bios i see no other strap ratio's

Pretty sure it's a lucid chip

nf200 is only pci-e 2.0
-new plx8747 are 3.0
-z77 sniper 3 has 1 also

Got tired of waiting for the Core i7 3770K and I don't think my loop will be able to handle the extra heat. Temps at stock idle is less than 30C(25C+) although ambient temps are in the near 30C range.

 

[LagunaX]

Why are you only at 3.6ghz?

Was doing a burn in at stock settings. Now I'm doing 4.5GHz @ 1.304V and lowering the voltages till I find the lowest limit that is possible at 4.5GHz. Tried at 1.35V earlier and passed Prime, LinX and IBT.

Ok, you realize that your idle temp can't really be below your ambient temperature without some sort of active cooling, right? The readings on those temp readouts are always less and less accurate the farther you get from the max, but reporting them like that are silly because it's physically impossible.

Manually controlled Noiseblocker XLPs @ 2kRPM cools everything, even at idle. Either that or I'm getting the wrong reading from my local weather station.

Thanks. :biggrin:

3.4Ghz 3570K HD 4000 vs 3870K

 

[podspi]

Impressive, Don! Have any gameplay benchies for us? Also, thoughts on IQ?

 

[BallaTheFeared]

lol Don, can you test it against the A8 with some real games/tests?
