OCUK Binned i7 7700k's - Only 4.8Ghz??

[RichUK]

They can all do 4.8Ghz....

I may be mistaken, but I read in another thread that binned Kaby Lake's would only be sold in bundles so I'm guessing this is it??

4.8 is a respectable clock speed I don't what your problem is. If you want high you will need to look at deliding the IHS and slapping a water cooling kit on it.

I think you missed the point....

I've already dellided a 7700k, I did that over 3 weeks ago.

 

[RichUK]

That's a massive 0.3Ghz overclock! A massive 7%!!!

But if you want real oomph grab a bargain:

That's more like it, but WTF at cost - just get rid of the bundles!!

 

[RichUK]

These bundles are a great way to offload the other bits that the majority don't want or need just for the allure of 5Ghz+, lol

 

[RichUK]

some stats from Derbau8r: "Golden chip 5.4Ghz, good chip 5.2Ghz and around 50% will hit around 5Ghz."

What volts, temps and test method?

 

[RichUK]

Kabylake is just boil in a bag Skylake, don't get sucked in by all the hype.

If you're all expecting to buy a random 7700K and just clock it to 4.8Ghz minimum you're in for a disappointment.

All reviews, leaks et al have had no issue whatsoever getting to 4.8ghz lol

Facts are facts.

 

[RichUK]

No issues? 1.4 Volts and more on £150 coolers and still boiling hot, that to me looks more like instructions from their Intel pay masters "get them clocked up there at all costs"

I don't have issues getting my DC to 4.8Ghz if that's the criteria... easy.

When testing with avx, but these binned cpus aren't tested with avx so won't get that hot.

 

[RichUK]

Stress testing no longer counts?

AVX is an extension, its not something thats only ever used in stress testing, its used in normal Desktop operations, Stress testing AVX is no different to Handbreak encoding or tessellated image rendering..

Correct. What's your point in this context, though? (not meaning to be rude).

EDIT: You can't buy binned 4.8Ghz chips and expect them to perform well in avx execution because OCUK omits this test case.

Actually I think I may have entangled (confused) your original point with the topic of this thread. Never mind.

What is true, they do get ridiculously hot when running an AVX workload, but 4.8Ghz seems achievable on most from what I've seen.

 

[RichUK]

The point is the 7700K is not really any better than the 6700K, and why would they be? its same chip on a more mature process, yes on average they might clock 200Mhz higher on the same sort of volts - temps, they arrive at a little higher stable clocks.

But they are still very hot even with very expensive coolers with very high volts if they arrive at those speeds the 6700K might not, the sort of temperatures and volts one wouldn't say was perfectly fine for a 6700K, yet suddenly we are to accept that it is because they renamed it?

Its a rather cynical move to overclock and rename a CPU because its more mature and then relaunch it and to do what seems to me force reviewers to get clocks out of them they normally wouldn't publicly or at least do that and tell you its completely normal and that you at home can expect the same.

If anything it give me hope for Zen as that to me looks a bit desperate, the later bins of 6700K's probably have the same characteristics and the 7700K

I agree 100%, and I do hope Zen delivers because Kaby Lake doesn't qualify as a new generation IMO.

If KabyLake does 7 hours swarm backing lighting in Unreal Engine @ 5Ghz - 1.36v i'll consider it a very golden chip, if 7 out of 10 do it and not throw an error at the end i'll eat my keyboard.

I'll give it a go - how do I test this?

 

[RichUK]

IIRC tests show that the Intel TIM is actually better than the vast majority of consumer TIM, when applied to the die. The real issue is the gap caused by the silicone glue.

Be interesting to see what 8 Pack says, but I noticed a minor gap between the IHS and PCB when I rested the IHS directly on the die (after completely removing the original adhesive and TIM).

So personally, I think this theory is false.

 

[RichUK]

Correct you are guessing, and you are mistaken.
They are not binned. It states no where on the page, that it's binned.

The components cost no more than they do alone, it's just that we're providing you with a guide for the Overclock, and recommending a suitable hardware configuration that we have tested, and know works.

OFC, you can just buy what you want and use 8packs settings or your own nothing stopping you. This is just a hardware configuration.

Fair enough, but the selling point is 4.8ghz.

 

[RichUK]

You are insreasingly, Oh dear every post you make.............. no the selling point is it works well together 24-7 with good performance. We sold 4.5ghz Skylake buindles at over two per day for the entire duration of Skylake simply because it works..... and is very easy to set up.

I mean if you want 5.4ghz at low volts I can do that too if you pay 2K per CPU............................... This bundle is aimed at everyone not the absolute pinnacle.

That's fair enough.

This thread might as well be closed now.
