As @Vario mentioned today if Cinebench use AVX, i am curious too

Edit: I ran CineBench using -1 AVX and clock speed didn't drop.

OMG..
Just putting this out there...
If you have a mixed metal cooling system aka aluminum rads, copper block use something like Hercules corrosion. Inhibitor.
It's $30 but gives you a lifetime supply at that price

That would be hilarious if someone does.
Dont forget to add saltwater to the cooling loop. It has a lower heat index and will help the mixed metals bond faster!

So I spent the afternoon optimizing the ram, bclk, and am about 50% into the video card. So far so good and all is stable with some decent increases without changing the cpu heat (which I feared being the controller for the ram is on the CPU). What I just figured out is I can control the pump and fans on the cpu watercooler which may cause me to start over now that I have a little more control over the heat situation. 5.3 with avx-1 may be attainable now with realistic temps, I will find out tomorrow. It also looks like I may have up to another 100mhz on the gpu and another 200mhz on the gpu ram but its a work in progress, and I have a 1080ti on loan to a friend that I should have back the end of this month anyway so I'm not too worried about the gpu right now.

Anyway I increased my passmark by 566 points which was impressive!

For those that were wondering I have some results:

I'm running at a super stable 5.2ghz AVX -1 with a healthy 1.424v without exceeding 90c in any test (I'm going op back the voltage down but I wanted the head room for testing).

I ran Prime95 stable for 1 hr = max 89c on one core <= 86c on the rest of the cores

I also ran firestrike v1.1 https://www.3dmark.com/3dm/30267016

Below are screenshots of the other tests I ran (all back to back with no reset). Unfortunately CPU-Z will not show my current score at these settings - it just keeps popping up with my 5.386ghz run @ 95c (which was unsustainable with my cooling solution)

Now to start clocking the ram.

@totalfreq what kind of temps are you hitting just on a cinebench run at 5.2 1.424 and your EVGA 240?

I have just put together an 8086k (delidded CLLP between die and RockitPro copper IHS and CLLP between the ihs and monoblock), z370 taichi, g.skill 32gb 3200 cl4 in a water loop with 2x 480 rads and a bitspower monoblock and I think I may have a dud of a chip. At 5.2 I need over 1.4v and cinebench slams my temps up to mid-high 90's almost immediately. Not to mention Realbench and other AVX stuff.

Right now I am at 5.1 @ 1.36v (manual volts 1.35 in bios, LLC auto)and a single cinebench run gets me in the mid 80s range.

I am thinking I may need to pull apart my loop, reseat my IHS, maybe put the original IHS back on in case the all copper one is just not making proper contact. Things seem out of whack. Although gaming temps barely brush 60C, which seems about right no?
@Knoxx29 @totalfreq Thoughts?

CLLP between the ihs and monoblock
Wait wait wait, let me see if i got this straight, you applied CLLP between the IHS and the Waterblock? i hope i misunderstood what you wrote

Correct. I had CLLP on my 4790k IHS and my raystorm block for about 2 years and I just took it apart last week. It leaves some stain, but a little lapping gets it to come right off.

The monoblock isn't aluminum so it should not be a problem. Have you heard otherwise?

sound like the members on this site?
No. I even am a delidder and I agree: Unless you are a hardcore enthusiast or something it really should be treated as a last resort measure.

I wouldn't go around calling members of this site tech-illiterate by the way, you might get stung.

As long as it is Nickel-plated you should be fine. Copper is even ok, but longevity suffers.

I would only recommend using CLLP between CPU die and IHS.
You may, but if you are really going all out there's no harm in applying it all over provided it's done carefully and correctly (I know I know, it's ironic this coming from "Mr. CPU socket murderer" but bear with me).

It's easy to screw up though so be cautious doing it.

Yeah I hear ya. Since I bought an IHS just for the chip I decided to CLLP the IHS to block as well. I'm likely going to do a teardown and use the original IHS and some regular paste since I don't to mess up the original IHS.

Your thoughts on my temps though? Does it seem odd?

@R-T-B yes the block is nickel-plated.

I am too paranoid about temps so i would say for a Delidded CPU that hit those temp with 2x 480 rads temps are high, however try as you said use the original IHS and some regular paste and see if something change

CLLP/CLLU tarnished my copper heatsink ages ago, required lapping to make it level again, but nickel plated probably okay.

Yeah I think that is what I will do. I appreciate your time. I'll come back when its done, it may take a while.

@Vario yeah my Raystorm is copper and it looks ugly, but a little lapping will clear it up and I'll re-use it. But was fine for about 2 years with liquid metal on it.

It left a white birdshit raised up alloy on the top that was rough to the touch. Good news was the pump died on the thing around that time, so despite fixing it with lapping, I ended up throwing it away. Given that the lid itself is nickel plated and those don't react to gallium, it will probably be okay.

@totalfreq what kind of temps are you hitting just on a cinebench run at 5.2 1.424 and your EVGA 240?

I have just put together an 8086k (delidded CLLP between die and RockitPro copper IHS and CLLP between the ihs and monoblock), z370 taichi, g.skill 32gb 3200 cl4 in a water loop with 2x 480 rads and a bitspower monoblock and I think I may have a dud of a chip. At 5.2 I need over 1.4v and cinebench slams my temps up to mid-high 90's almost immediately. Not to mention Realbench and other AVX stuff.

Right now I am at 5.1 @ 1.36v (manual volts 1.35 in bios, LLC auto)and a single cinebench run gets me in the mid 80s range.

I will have to check later - I dont have the PC setup at the moment but I always test with HWMon open and I wouldnt have settled at 5.2 if it were in the 90s (I would have declocked). Also I'm not delidded so you should be even lower. I'll test again though and let you know.

Speed stepping, hibernate, sleep - all BS that I turn off. I asic mine at home so my power bill is already around $700-1000/mo so the extra 100w+ for the cpu and HDD really doesnt affect my power bill. Also, over the years Ive seen tremedous data loss from sleep and hibernate modes - I wouldnt recommend ever using them.

Turns out I had applied too little liquid metal on the IHS -> monoblock. When I took it apart there was barely any residue on the monoblock itself. I only applied a thin layer to the IHS, not to the monoblock as well so my contact was not ideal. When I do the die -> IHS I put a thin layer on both to make sure adhesion is good but since I have also killed parts with liquid metal in the past I went a little too shy on my application for the IHS -> monoblock for fear of a spill over.

Anyway, I put the original IHS back on with liquid metal between the die and IHS, then EK TIM between the IHS and monoblock. Temps are much better now. But I don't know about getting up to 1.42+ volts to get 5.3 stable . You must have a nice chip on your hands @Knoxx29 and I'm sure the water chiller helps.

Glad to hear you found where the issue was.

Delidding sometimes helps with voltages but unfortunately it doesn't always works that way it looks like you got a power hungry CPU and you can't do much about it maybe tweaking it a little bit could help with voltages.

You must have a nice chip on your hands @Knoxx29 and I'm sure the water chiller helps.
I guess so, the Chiller helps just when Benching.

@totalfreq what kind of temps are you hitting just on a cinebench run at 5.2 1.424 and your EVGA 240?

I have just put together an 8086k (delidded CLLP between die and RockitPro copper IHS and CLLP between the ihs and monoblock), z370 taichi, g.skill 32gb 3200 cl4 in a water loop with 2x 480 rads and a bitspower monoblock and I think I may have a dud of a chip. At 5.2 I need over 1.4v and cinebench slams my temps up to mid-high 90's almost immediately. Not to mention Realbench and other AVX stuff.

Right now I am at 5.1 @ 1.36v (manual volts 1.35 in bios, LLC auto)and a single cinebench run gets me in the mid 80s range.

I am thinking I may need to pull apart my loop, reseat my IHS, maybe put the original IHS back on in case the all copper one is just not making proper contact. Things seem out of whack. Although gaming temps barely brush 60C, which seems about right no?

So I just got everything setup, (had the system off this weekend as I'm playing with a new one lol). I opened HWMon, and then ran Realbench so I wasnt on a cool/startup run and I then ran Cinebench15 through the GPU/Multi/Single and took a screenshot.

To note I have done a little more tweaking since the last bench upping my blck 0.5% to get around 5.23ghz AVX -1 stable. I also have my 3200mhz ram dialed in to 14-14-14-34 @ 3750Mhz which has raised my heat a bit due to the controller being on the CPU, but I'm happy if my max bench temp stays 10% below throttle as my real use temps will be at worst in the 60-70c ranges. I'f I drop the ram OC back down to say 3300mhz my cpu core temps drop down to around max 88c.

Remember I'm using an off the shelf clc, not delidded, but I did use my own thermal paste (generous but not overkill).

That's decent for off the shelf CLC non delidded, with your settings. You could probably drop temps around 10c by delidding and liquid metal, personally i'm uncomfortable with anything over 85c, 90c would be a big no no for me.

Lucky you, anything over 50c and i start tearing my hair out:roll:

You could probably drop temps around 10c by delidding and liquid metal,
If he is lucky 15c/20c, the max drop i got was 25c with a 3700K

I'm not too afraid of running a processor within its spec. I pushed my first P233MMX up to 290mhz back in the mid 90s and ran it for about 8 years without issue (other than it being too slow 6 months later lol). I also saw puffs of smoke come out the back of PCs as other OC'd chips blew over the years - Ive learned how to overclock through trial and error, and do it manually with my voltages all the way up and the clocks all the way down working backwards watching thermals. Though you may not be comfortable with 90c (or 50C for Knoxx), 90c on a bench is still 10% below thermal throttle limit and I'll likely never see it in realworld application for any extended period of time. Also the vcore limit is above 1.5 and I'm no where near that so my maximum current capacity is still "processor safe".

In testing I had the ram up at 4000mhz and I hit 95c on prime 95 before the 5min mark (when things really cook) . I shut it all down and declocked. Reason is the memory controller is on the CPU. I can either choose to clock up the CPU or the RAM or find a happy medium which is where Im at. Even though in real world I'd likely never still see the thermal throttle that prime 95 would have hit, that was outside my comfort zone.

If I'm going to delid and go custom (which I dont have time for right now), I'm heading to what the cool kids call phase change. I've been in refrigeration for the past decade+, and have my EPA license so I can buy/build the cool (no pun intended) toys most people cant. I have a few direct expansion (read phase change) air conditioners lying around I have considered parting out to build a CPU/GPU cooler, but just dont have the time right now. One day maybe.

The other thing I'm considering is immersion. Not for my computer, but for my ASICs. I currently crypto mine and run my ASICs at a whopping 150% average overclock. My issue is heat. I basically use fans on their side of the ASICs to create forced induction, and then actual condition the air using direct expansion cooling which is quite power hungry, but its still more profitable than running them without OC in a non AC room. But Ive toyed with how I can get an even greater overclock, using more efficient cooling. My thought is to not only drop an ASIC in mineral oil (for 8x heat dissipation vs air), but then (thanks to KNOXX), run the mineral oil through a fish tank chiller....It would be cheaper than my current cooling and probably net me additional OC headroom...my concern is KABOOM! Ive seen transformers blow during hurricanes and that mineral oil make one heck of green ball of fire. If I get brave enough to try it I'lll post the info.

For now though - im happy with my current build above 5Ghz using off the shelf parts.

Max core temp is 98C (Tjunction). Intel recommend a max of 72C for (Tcase) (entire CPU). That's conservative, but 80c+ is a nono for me.
