Caseking delided CPUs

So I'm looking at this shop, and noticed that they will be selling delided Coffe Lake CPUs.

But here comes the question ... is that cheapest delided CPU chery picked? Not in the good way, but in the bad one.

 

So they had a bunch of CPUs, and try to overclock them. Those that overclocked to 5,2GHz are being sold for 430€.

Those who failed 5,2, but passed 5,1 are marked at 390€, those who failed 5,1 but could get to 5,0 are being sold for 360€, those which failed 5,0 but works fine at 4,9GHz are sold for 330€, and lastly those that could work at 4,8GHz but nothing more, are being sold for 300€.

 

So by that logic, whoever is going to buy version for 300€ that can pass 4,8GHz, most likely won't work at anything above it. Otherwise they would just sell it for higher price right?

At first I was excited to see that delided CPU can cost only 30€ more than normal one, but now it doesn't seems like great idea, since delided one advertised to work at 4,8GHz is probably the worth of all those CPUs.

 

Any thoughts?

Yes that's the whole point with the pricing. They take the risk of delidding (though there going to be pros and use proper tools unlike some people so its not much of a risk) and testing the CPU for you. There selling you the CPU based on what they were able to clock it too. If you wanna a better CPU from them they want more money since instead of hitting the silicon lottery you already know what your chip is capable of so its what your willing to pay for the best clock. If you buy a normal chip and delid it yourself you are going to get a chip somewhere between the  4.8 and 5.2Ghz range. They just guarantee what you get and because of that charge you more money for the guarantee + delid.

In that case I will rather buy original CPU and just hope it won't be overheating on 5GHz.

There are a lot of reports that coffe-lake shouldn't have any problems going to 5GHz.

 

Just not sure if I should buy boxed version or tray. 

I suspect that if they find CPU that can't clock higher than 4,7GHz, they just sell it as "tray" without any box etc. 

Probably better to pay 10€ more and get boxed version ... at least that way I know no one has tempered that CPU and "reverse cherry picked" it  

 

Just need to wait for some users to buy that CPU, and report what temps they get at 5GHz without deliding. Should be lower than i7 8700k since this one does have hyper-threading.

Even the 4.8 Ghz one may be worth the money, because you wouldn't have to buy the tool to delid the cpu yourself.

Also, it gives you the opportunity to apply liquid metal on the cpu in order to reduce the temperatures by up to 20 degrees celsius in some cases, making the cpu cooler and potentially capable of running on air cooler instead of water coolers.

I saw one review when guy tested i5 8600k at 5,1GHz and got max temperature of 75°C on air cooling. So if others will get same results, I will just go for it. 75°C is more than fine for me, when CPU is being under Aida64 load. That means it probably won't go over 70°C in real usage. Not to mention that I would clock it to 5GHz instead of 5,1.

 

I will most likely be going from Ryzen 1700 8c/16t CPU to just 6c/6t CPU from Intel, only because I lack single core performance for MMORPG games.

@Simon771 ,  i was thinking of GamersNexus article and their video. They got bad luck with their 8700k CPU, which they could only overclock up to 4.9 Ghz at 1.4v

When testing Blender with a 4.9GHz frequency and 1.4 core voltage, our 8700K with Intel TIM and an NZXT X62 landed at 76C average core temperature, with a 10-second peak of 76.6C and a liquid temperature of 40.65C. The liquid metal version at the same frequency and voltage measured at 52.59C, or a reduction in average core temperature of nearly 24C.

 

Liquid temperature measured about the same as before, at 39.82C. Looking into this further, we realized that, measured at a current clamp on the EPS12V rails, the 8700K with TIM was drawing about 10-20W more power at the same voltage and frequency. We’re not yet positive, but our present theory is that this outcome is a result of power leakage reduction on the CPU as a result of improved energy transfer efficiency from the die to the IHS.

 

So you get around 20c cooler chip, and you get a chip that consumes 10-20w less at the vrm input (the output of the vrm gives up to 130w to cpu). Less power means also slightly cooler vrm, so it may be worth applying this liquid metal material.

 

And it goes on even with a more relaxed overclocking, 1.35v and 4.7 Ghz :

The TIM test plants us at 62.6C average core temperature, with the 10-second high at 63.82C. Liquid temperature is effectively matched to the liquid metal version, at 39.6C versus 39.8C. This is within our test resolution and error. Using Conductonaut, we’re at 52.59C, for a 10-degree reduction in average core temperature.

If you look at the description of one of the CPUs, it says they're binned by caseking/der8auer. The more expensive line also has a silver IHS.

 

I'd say wait for some statistics on what OCs people reach with regular off-the-shelf CPUs and if it's close to 5 or 5.2 Ghz don't bother spending more for a binned processor unless you're very enthusiastic about overclocking.

They really received bad overclocker.

But that's i7 8700k you are talking about. i5 8600k should be easier to OC, due to lack of hyperthreading ... so that's already saving some power.

I would surely like to have delided CPU and don't bother doing that myself. But I don't feel like spending so much more money on it.

 

And your post is actually good news for me. 6c/12t 4,9GHz at 1,4V can run under 80°C.

So 6c/6t shouldn't have any huge problems with thermals ... I'm guessing it should be at least 5°C cooler than i7 8700k.

I'm pretty sure 99,9% of coffe lake CPUs will be able to clock to 4,8GHz. So I think I will take my chances and just buy normal one.

 

Other reports are saying that i5 8600k can run at 5,0GHz with 1,35V or even less. Even if I get unlucky, I don't think I will be stuck with chip that can't get to 4,8GHz at least. And if it comes to that ... well at least temps will be lower

Yeah I saw that silver IHS ... not interested in that lol

I will wait for other users to test their luck, but I'm certain that 4,8GHz is something every cheap will do, 5,0GHz probbably the same, and anything over that will be like Ryzen 4,0GHz. Hard but possible.

I would recommend just that since I really don't see the point in the binned CPUs. If you look at the prices and consider that 389 EUR can get you an i7 8700k... (yeah it's Tray but if you're gonna OC it you're gonna use an aftermarket cooler anyways.)

I already have dark rock 3, that can take care of 180W power hungry CPU. Should be more than enough, but I can always put another fan on it, and increase it's cooling capabilities. 

Buying i5 8600k for 270€ + motherboard for 170€ doesn't sounds so bad since I can also sell my Ryzen 1700 and motherboard for 300€.

But I won't be buying it until there are more reviews and tests out there.

 

I'm also hoping someone who is playing Black Desert Online can test that CPU in game and see if it helps with unstable lag due bad optimization.

The cooler is great but to be honest, I don't think the upgrade you have in mind would be worth it. I'd stick with the R7 1700.
