I don't think that demand is so high. If you count how many users are delidding then it's actually only few, even for enthusiasts. In some countries 1 tool has 10+ owners. In Poland whole forum shared one 115x tool or one guy was delidding for others. In total delidding tools for 115x were available about 2 months after all the noise in the news. Still der8auer tool was available half year later when all who wanted, already got other brand tools. Now think how many users got 2066 chips ... and barely anyone decided to delid them. So I just think that high price is caused by very limited demand so they have to cover costs of designing and production even though it looks pretty simple.



I actually like that as on most other forums you just can feel stupid kids with too much money trying to prove others how good overclockers they are using someone else's basic guides.

It is the first time since Ivy Bridge years that I see first time builders asking on how to de-lid on this very forum. Never seen it before.

It's not because they need it ... they read BS threads and they think it's required, one friend asked me if I can give him delidding tool for SB and he is not even overclocking much above stock ... all because he saw that somewhere

My point is only that those who are delidding are making it on unlocked i5/i7 CPUs. These series are really low % of all CPU sales. Even lower % are in hands of those who are delidding. Based on that ( and stores sales ) I can say that overall sales of delidding tools are really low so manufacturers have to bump prices so it will give them any reasonable profit.

I totally agrre with you on the first part of your post.

Regarding the second part, if orders have been increased by a x3 factor, eveb if it is still marginal, price increases. Not an absolute, but a relative tag ;)

To keep things going, just saw tracking on my delid tool. It is about to fly over from Germany so I don't expect to get it until next week, where I have to go away for work travel so it wont be until the week after that before I can get to try it.

Caseking is shipping most stuff to EU countries in about 1-3 days. To Poland it took 2 days but I actually have closer to their store than to Warsaw ;)

The tool should arrive by lunchtime according to tracking. I put the order in last Tuesday, had dispatch notification on Wednesday, with delivery ending up scheduled for Saturday. Since I picked my work address I had to request they delay until today so someone will be there. Although I want to do a proper job on it, I think I can't resist doing a delid tonight to see what difference it makes.

Delid and LM done. On 7800X, at my 4.3 GHz 1.1v OC, running 12x 64k FFT on Prime95 (over an hour to allow water loop to warm up), I got:

Before, after, drop:

Max
73 63 10
73 68 5
76 65 10
77 72 5
74 68 6
75 66 9

Core spread (hottest - coolest) before 4, after 9

Average
68 60 8
70 66 4
73 63 10
73 68 5
71 66 5
73 63 10

Core spread before 5, after 8

Ambient before 21.8 after 22.2 so not significant change.

A mixed bag there, I wonder if there is either something uneven about my LM application, or non-flat seating of IHS on die. Temps went down 5C on both hottest core max and average but a bit variable overall. I'm thinking of moving this back into its old case later on to improve water cooling capacity, and can look at the application again at that time.

Side note: I looked at VRM temps afterwards only, it logged a peak of 90C as reported by mobo. When should I get concerned? :D

The results from your delidding and use of LM on the core/inner IHS seems consistent with what I saw when I did mine. I'm thinking maybe these later Skylake-X processors are getting better TIM application from Intel than previously?

Pretty awesome tool there,tho i think i might have a small heart attack delidding a i9 7920X from the stress alone lol.

Hah, I keep thinking about it with my 7920x. I do have a slight problem, USPS seems to have lost my 7920x in transit... Was supposed to be here Monday but tracking hasn't been updated since...

I guess that if 7920X was available earlier then I would get one instead of 7900X but I'm not really complaining as my 7900X OC quite good comparing to what I see around the web.

I'm using it mainly for tests/reviews but recently I was switching platforms and I was even playing games :) ... It runs at 4.5GHz 1.15V for most of the time. I'm using 2x360 slim rads but it's barely ever under 100% load.

btw. 4000 17-17-17 / Patriot Viper4 3733 on Taichi XE and at 3400MHz cache. bandwidth is a bit lower than I was expecting but it's maybe because of early BIOS

Dang nicely done. Your L3 is much much faster than mine. Are you adding volts to the mesh to get it to overclock so much?

1.2V mesh but something isn't stable at these settings. It passed about 20 mins AIDA64 so it's not bad. On the other hand on ASUS mobo I couldn't even run tests above 3200.
L3 is related to couple of things like cache frequency but also some others. When you have too many power saving options enabled then cache bandwidth will be lower.
