Devil's advocate here, lol Of course a lot better. Still the system looks like it is not perfectly tuned. 4.8ghz CBR15 should give you 4700++ CB points. Congrats though. Seems pretty much spot on.

I am going to try and help ( if possible ). Here is the most detailed procedure I FOLLOW when delidding . I always use der8auer's tools. So, 1) Obviously the IHS is correctly removed. 2) Remove all factory black silicon from the perimeter of the pcb. 3) Clean everything very well with isopropyl alcohol. Wipe the die with soft cloth. Lap the inner part of the IHS with 320-800-1500 sand paper until the bronze appears and mirror shine it. 4) Apply a very small quantity of thermal Grizzly Kryonaut both on the die and IHS and apply evenly down to a very thin layer. 5) Apply new high temp black gasket silicon on the perimeter of the IHS. 6) Re-insert the cpu with the IHS correctly aligned on the pcb in the delid tool and use the curing pressure element of the tool to establish firm connection. DONT use extreme pressure. 7) Let it cure for 24 hours. If nothing else is wrong, install the cpu and use carefully a thin layer of Thermal Grizzly condactonaut on the IHS. Apply your waterblock. Normally you are done.

This is my daily setting. I can go as high as 4.9 core, 3.2 uncore with 1.31V and 2.10VccIN with LLC7 for 2D and 5.0ghz with 1.325V for 3D and still I am below 85c in the hottest core.

^^^^^^^^ I have to agree with Allen ( Splave ). Running mine at 4.7ghz with 1.19Vcore set in bios, 2.00VccIN, 3.0ghz uncore with 1.12V and Real Bench v2.43 looping for 1 hour, results in 67c max in the hottest core. Something is definitely very wrong. 2 X EX420 rads and a double D5 ( EKWB ) pump here. LLC6

It is a retail chip. I have also delidded my chip with Roman's tool. As Firekiller ( Stavros ) - good man and personal friend - advised in another thread, lapping the die is useless unless you use direct on-die cooling. Besides that it is pretty dangerous. I personally would never try doing something like that. I do not have the knowledge, nor the experience to play Russian roulette with a 2000 Euros cpu.

Hi, Although my problem is not so big as yours ( I had a serious issue with cores 2 and 12 ), the only solution I thought of was to go to bios, select per core adjustment and lower the multiplier ( and voltage ) of these two cores by 1 step. Meaning, running 16 cores at 48X with 1.26V and the two "problematic" cores at 47X with 1.22V. This ironed out the big fluctuations at a +/- 5c under load status.

Nope, 1 cpu. First buyer failed to pay according to PayPal rules and I sent you a message since you were "second in queue" Did not get a reply and re-listed.

Still available :) 200 Euros for a 5.5ghz I5-7640X cpu on ambient water folks.

Bump Price wont drop folks, not one Euro. Either it sells or I keep it.

5.5 / 5.0 - 1.43V

This is a re-list due to irresponsible buyer. Check out the link for the original listing. N.B. PLEASE, do not waste my time if you really do not want to buy or if you wish to pay with non-approved methods.

Processor sold to OC.Queen. Item has been paid. Thread can be moved and closed. Thank you for the space HWBOT

Pending payment from OC. Queen

Hi all, Pictures are 1000 words, so check out the plethora of screenshots uploaded. Boxed I5-7640X, warranty valid till 09/2020. De-lidded with Roman's tool and resealed to factory specs after being treated with Thermal Grizzly Condactonaut. This is a potential 7ghz+ cpu, very good for legacy benchmarks and PI's. Asking 200 Euro + shipping. PayPal please. Item is located in Greece and seller ships in one day after cleared payment. Private sale - no personal warranty and no returns. P.S. Test platform Suboptimal water cooling with an XSPC AX360 rad and an XSPC single D5 pump. Ambient temp 25c. On Apex VI.

Thanks man. Appreciate the prompt reply. Best, George

Forgot to mention also, Zotac GTX 1080 Ti AMP edition. Three months old. Boxed with accessories. 700 Euros shipped. George

Hey bud, I have a Gigabyte G1 gaming rev.1 GTX 1070. Pristine condition, but no box. 400 Euros shipped to you. Pm if interested.

Very well said - Bravo

Outstanding - truly outstanding friends N.1
