The Desktop

 

This one... LPX 4000. Will be here tomorrow. I've got to pull the RAM out that I sold later this afternoon and ship it and the 7700K to the buyer. So, I will use only the P870DM-G until it arrives tomorrow.

 

Hot damn...$496. Imma stick with my CL14 3466

 

Yeah, totally nuts and unacceptable pricing. Had I not sold the 7700K and the 32GB of G.SKILL 3200 for $500 (before fleaBay fees) I never would have done it, but that almost covered it. And, since it is 4 sticks I will be ready for quad channel if I update the mobo and CPU to i9 HEDT someday. Since we were able to run Brother @Johnksss LPX 3600 at 4100 with tight timings in the Maximus X, I've got high expectations for this LPX 4000 RAM. Like maybe 4133 or 4200 @ CL16 or CL17.

 

Looks like what I ordered made the ASUS QVL list at 1.35V. So, I can probably bump it up to 1.40V or 1.45V to tighten up the timings and squeeze more clocks out of it.

No heat problems at those voltages, although those ram coolers with the flashing lights are awfully pretty

 

Yeah, I am not too worried about the heat. The G.SKILL 3200 sticks that I had in the P870DM3 had temperature sensors on them and when I had them overclocked and running 1.45V and 1.50V they never got above like 55°C. Considering they had decals, no heat spreaders and were stuffed in a hot laptop, that's not too bad. Should not be hard to keep them cool enough in my desktop.

Yeah, I really like the way the RGB memory looks, but it's already so ridiculously overpriced that I'm just not going to pay extra for pretty lights. Plus, I will have the Corsair cooler thingamajig on top of them anyhow, so would be kind of pointless with them covered up.

 

Yeah, I am already second-guessing myself. Probably should have just kept the G.SKILL 3200 sticks and used the money for this instead. I think that would have been a lot smarter on my part. But, it's too late now since I sold what I had, LOL. Hindsight is always 20/20.

Wow that isnt all that expensive!

Maybe sometime in the future

 

Definitely. The good thing about lots of this stuff (RAM, cooling parts, PSU, case, etc.) is that you buy it once and only change out GPUs, mobos and CPUs. Way better than buying a new laptop. These are parts that we can use for years, until they die or get too old and worn out to keep using them. That makes the expenditure not nearly as frivolous and foolish as the laptop money pit.

 

Exactly!

Like when i moved from the 6850k to the 8700k, all i swapped out was the motherboard and processor. And recovered about 60% of the cost

 

And a good thing....

That one is 1/2 hp - 2700 BTU max flow of 800
Mine is a 1/3 hp - 4000 BTU max flow 2400

And if you really wanted it (And I found the one I wanted) I would give it to you for a good price.

Also, I change the block to an EK block. When I got home I notice that it was taking to long to pull down temps. Notice the block was just having major issues passing the water through. That's why we didn't see really any droplets of water. This I know because there was a puddle sitting on top of my EK block when the temps were sitting at 40F. I cut power to board and dried it up before it fell on board.

 

Sounds like a plan. When you are ready to sell it, let me know.

 

Will do!

........... @bloodhawk
Thanks to this ^ guy right here who talked me into getting it. LOL

 

LOL

Hey either way you look at it its a sweet sweet chip specially in the hands of someone like you.

Cant wait for Intel get their **** together and ship out my replacement, so that i can actually put mine to good use.. finally manged to pull these out of storage, totally forgot i had purchased QDC's when i was first thinking about the chiller -

 

are you kidding meeeeeeeeeee

wtf @bloodhawk, what did you DO! giving @Johnksss a chip like that, MADNESS!

Oh nono thats not mine. Though i would not have had any qualms about loaning mine since up until 2 weeks back it was literally just sitting in the box XD

He ended up up picking up his own after a teeny tiny poke.

 

Its weird really. I just set that from the bios with everything at auto and it booted and validated.

Right now it's running realbench stress test at 4.4 [email protected] to see if it's silicon lottery material.

 

with u it seems to always be SL material its like hardware just bows to your will while resisting all the rest of us

 

Nope. Actually quite the opposite. Look at my 8700K. That one is not as good as everyone else.

 

havent looked at it yet. how is it doing?

 

About 5.2 ghz or so bench able in laptop and on desktop board. If it was a good chip I would have kept my Z370 Apex board.

 

Didn't you get yours early? 5.2 GHz is nothing to scoff at. Have a look at the statistics from before the process matured to today's levels.

I get the jealousy towards Mr. Fox's sample though.

 

interesting that ud run into the same limits on both laptop and desktop. 5.2 is nothing to sneer at though! but sure, disappointing to only reach the "regular" limit of "normal" overclockers when compared to your usual standards

btw guys, i have a request to anyone with time, nerves and a laptop equipped with an 8700k:

check and see at what vcore and allcore boost clocks your 8700k reaches roughly 120W on package when testing p95 avx load with 1344k FFTs in 15 min intervalls. delta T would be nice as well

no need to run it for a long time, just a quick test to see package watts and vcore at load in hwinfo64 reps and likes to anyone who could provide this data! cheers!

STOCK I7 8700 ,BIOS 1003
1,024v


prime95 small ffts

 

I kept my X99 board as the X boards seem to retain value and even go up in value as they become harder to find. I plan to put in a 10 core eventually when prices come down a bit.

 

Yeah im getting mine RMA'd. Lets see what i do with it once it comes back.

 

OK, got the new RAM. Ran a TM5 with the stock XMP-4000 profile and passed to make sure it was good. Then rebooted and overclocked it. Already tightened up the timings and might be able to tighten more. I'm liking it. Good speed and low latency.

Spoiler: Check it out...

@Phoenix - I know you like AIDA64 RAM benchmarks, bru @j95 @Papusan @Robbo99999 and @jaybee83 like it, too. Glad I got the same brand as Brother @Johnksss instead of the G.SKILL. Now maybe I can eek out a few more points for the @Prema HWBOT team.

I saw they have DDR4-4000 SODIMM on NewEgg now. Whether they actually work or not is another story, but they got 'em.

 

I think I am going to cut the side brackets down on the fan to lower it close to the RAM/motherboard. I don't like the big 1-inch space between the fan and the RAM. I think it would look better with a 1/4-inch space, even if it doesn't do much. Or, maybe I will just take it off. I don't know that it actually needs it. Probably doesn't need it.


Yeah... looks better naked, LOL. What does @KY_BULLET think? With or without?

 

Those arent for laptops. They for a specific X299 motherboard and those are likely quad channel kits.You probably need to get taiphoon burner to have different timings.

Which ironically, would be pretty garbage for X299 since each channel would only get one rank of memory. Hence you probably can lose around 20-30% memory performance compared with 3200mhz dual ranked.

Also, I have no idea if your Clevo laptop's algo for training tertiary timings would even cover that type of kits, those are some VERY aggressive timing kits. @Prema to comment further on that.

 

well see how well they work in a P751DM

@Johnksss already tried and tested the 3800 kit by corsair in his machine, got it up to 3466/3600

not saying the xmp 4000 profile will just work but VERY curious to see what can be done by manual tuning

Yeah, lowered the profile of the fan quite a bit by shortening one of the legs that clamps it to the RAM. Notice the clearance between the fan and the coolant line now compared to before.

 

slowly but surely approaching quad-channel bandwidths there

btw i kinda like the industrial / raw powah look of the fan assembly on the RAM, but ure right in that it looks better / cleaner with the retention brackets shortened. good job there

 

Looks good but you might have to change your led's to red to match or just box it up and mail it to me

 

What do you think about bios 1001

 

Much prettier naked. Why must they have everything so flashy colors?

 

If you meant to say 1101, Mr. Fox posted it here.

 

I cannot say how they would fare in a laptop (some tweaks may be required, assuming the user's laptop has a BIOS which supports it), but based on how mine are running in the Mighty Mini, I would think they would be just fine.

BTW, check the images for the board used in GSkill's marketing material:

http://gskill.com/en/press/view/g-s...so-dimm-kit-at-3466mhz-cl17-17-17-37--4x16gb-

http://gskill.com/en/press/view/g-s...so-dimm-at-4000mhz-cl18-18-18-38-32gb--4x8gb-

My understanding was that quad vs. triple vs. dual are all properties of the motherboard on how many MIMMs it sanctions off for the number of modules in use. So, something branded as quad could be used in a dual motherboard, but they will just run in dual channel config.

Assuming the capabilities found in these GSkills are probably tighter than current laptops settings, I think it should be safe to run. However, I dunno if their XMP profiles would work, or if the laptop would just ignore them and go with settings more attuned to its memory expectations.

 

That is correct, it is a motherboard/chipset/CPU feature that is dependent on slot population to function, not the modules. There may be some that an OEM claims to be "optimized" for a specific configuration, (some of which may be nothing more than marketing crapola,) but it is entirely dependent on how many sticks and what slots are filled vs empty. Dual, triple and quad cannot work if the slots are not correctly populated.

i think the same about my wife, but she likes to wear flashy clothes.

 

nice! xD

Congrats on the new RAM Mr Fox! Your latency is about 1ns less with this RAM in comparison to your previous memory, if I recall, or was that JohnKss's RAM - how much less latency you have with your new kit vs your previous G-Skill Ripjaws V? I guess your bandwidth is higher though with this new one, how much? Kit looks good installed, how much difference in temperatures does the RAM fan make, might not be worth running it? Any positive changes to benchmark scores or real world use at all? (Ha, that's a lot of questions - sorry!)

 

Thanks, bro. I do not have a way to check the temperatures, so I do not know how much improvement the fan makes. I do like how it looks without it, but it looks a lot better with the brackets modded to keep a lower profile. Speeds and latency are show in the screen shot. As usual/expected, differences in benchmarks that are not RAM benchmarks are very slight and mostly unremarkable. Pretty amazing that my memory is running faster than the CPU core clocks in most turdbooks, LOL.

 

Cool, how much latency decrease & bandwidth increase did you gain vs the GSkill Ripjaws V for your max overclock on both? Have you got a side to side screenshot of AIDA for both of them?

(Oh yeah, you disabled some monitoring facilities on your motherboard to gain better performance, I'm guessing that's why you don't have RAM temperatures)

 

I will look through old screen shots from a comparison. No, I have not disabled that. Neither my G.SKILL 3200 nor the new Corsair 4000 RAM have temperature sensors. My Kingston SO-DIMMS in Machete have none. The only RAM I know of that had them were the G.SILL SO-DIMMs I had in previously-owned Clevos. No other RAM I have ever owned had thermal sensors.

 

That's weird, my G-Skill Ripjaws V have temperature sensors, strange that your Ripjaws V didn't. Cool, will be good to see a comparison of those screenshots you mentioned because that way you can see the 'raw performance' difference of the RAM.

 

Interesting even my TridentZ has temp sensors, and the Corsair Dominators before that had temperature sensors as well.

 

Yeah, I am not sure why that is. My HyperX Impact SO-DIMMs , my desktop G.SKILL Ripjaws V and Corsair Vengeance DDR4-3000 SO-DIMMs that I tested amd RMA'd for the P870DM3 had no thermal sensors. Seems like something all of them should have as a standard feature.

 

Here you go, bro. Pretty huge change across the spectrum.

Picked up the wifey a new BGA turdbook today for work/school (going back for the doctorate). Why am I so impressed with this little thing.

I have to tear it apart and upgrade it with the 8gb ddr4 I have sitting around to give her dual channel 16gb.
