I9 9900k

This worth a change from my binned 5.1 8700k delidded from OcUK?

The 9900k is a fantastic cpu but like the 8700k, whether or not you will be able to clock it as high as 5.1GHz depends entirely on the quality of the silicon you get. You may end up with a 9900k that only does 4.9GHz or you may get one that does 5.4GHz or higher as well as anything in between.

Will you use the extra cores of the 9900k vs the 8700k? If you just want extra threads have you considered Ryzen? If you want extra threads and speed have you considered Zen 2 expected to release around July?

I went from 8700k to 9900k and I don't have any regrets at all. I use the extra cores and managed to get a good overclocker, AND I wasn't prepared to wait 6-8 months for Zen 2 to release. If I had an 8700k now and wanted more performance for less than the asking price of a 9900k I might be tempted to wait with Zen 2 expected in 2-3 months. Then again what people know about Zen 2 is still largely rumours and conjecture right now.

If you can afford it and want the best then the 9900k is hard to beat. But if you arent going to use the threads and you lose the lottery then you might end up with less performance compared to your 5.1GHz 8700k in anything that values clock speed over threads.

I would say if you don't know whether you need to upgrade then you should hold off for a while. On the other hand if your 8700k dies tomorrow and you need a drop in replacement then the 9900k is a great option if you will use the extra cores over the 8700k.

because of the indium the bond is stronger, and it dislodged the die or cracked it. der8auer now puts heat on the ihs before delidding.

delidding is not 100% safe as some people think it is. i killed my 4770k with a delid tool.

Do you happen to have a link to the video? I've watched quite a few but haven't heard him say he has damaged a 9900k during delidding. In fact in the ones I have seen he states the opposite which is why I'm thinking perhaps I have missed one.

It's the one (or at least one of them is) where Steve from Gamers Nexus is lapping a CPU with Kingpin at EVGA. And Steve mentions what happened to Der8auer's chip.

It can't be that one, that refers to the 9980xe that Der8auer delidded. He knocked a bunch of 'SMD components' off of it because he didn't know they were there. That is the same CPU that Kingpin and steve are talking about in the gamers nexus video, not the 9900k.

Ah, my bad. I only remembered the mention of damaging a chip in that vid. You're wanting to know whether 9900K specifically.

Yup, in the video i have seen Der8auer says that he hasn't damaged a single 9900k and that delidding it is perfectly safe. That has also been my experience, but if he has damaged a 9900k since then I would be interested to hear about it here. There is risk with any delidding of course, but as far as I am aware, delidding a 9900k is no more risky than delidding an 8700k. The solder is so soft that there really is little difference in the process between the two. Especially if you use a delid tool.

The 9980xe on the other hand has surface mounted parts and they always come with risk because shifting the IHS could mean knocking them off. Any CPU with surface mounted components beneath or near the IHS becomes riskier to delid as a result but that doesn't make it unsafe if you know where they are and have the tools at hand to delid while avoiding them.

I don't want to be telling people that delidding a 9900k is safe if that isn't the case. Right now I believe it is but if there is evidence to the contrary I'd love to see it to avoid passing on bad info.

indeed it is


just because yoiu have never broken a CPU delidding docent mean it hasn't happened , as said i broke a 4770k with a tool.
i think the size of the die make a deference, when i did skylake i5 the ihs came off with no force at all. the 4770k i have to really crank at it, the second 4770k was hard but not as hard as the first and was a working delid.

i may just be luck of the draw, the could be 1 bad in 10,000 but if that one it yours it sucks

I've delidded four of them, no problems at all.

No different than the older models except more force needed. I think people have cracked the edges off them if using a razor to clean the solder off, bit too heavy handed or lapse in concentration
 
Slips with a blade, cutting traces and the like seems to be the most common issue. That's down to carelessness and applies to delidding any cpu rather than specific issues with delidding the 9900k itself.

Using a delid tool to pop the ihs off and then a plastic card and/or rockitt quicksilver to remove the solder makes it hard to damage anything even if you try. You certainly wont be scratching the silicon or the traces with a plastic card, and thats all that is needed since the solder is so soft.

If using a blade go slow and take off a small amount at a time being careful of the corners, the angle of the blade, and in particular keeping the blade clear of the pcb. Rushing or not paying attention if you choose to take a razor blade to a £500 cpu is madness, and yet the failed delids are largely stories of "tifu by using something pointy near my expensive cpu".

In my experience of the 8 and 9 series there is very little to get wrong if you approach the delid with patience and care. I haven't used a razor blade but i know many do without issue when propper care is taken.

I think he was talking about a different CPU there, I think either the 9980XE or the 7980XE.
