I think you misunderstand. I never said it wouldn't run fine at 4.0 ghz in games. Where did you dig that up at?

Again, I don't care about this BGA vs Socket argument. That is not my thing.

I think you better go have a second look at games benched or ran at 3.6 vs 4.0 ghz. There is a difference. That was all I was getting at. Nothing more.
Most games use the speed of a single or maybe 2 cores, and the sweet spot seems to be 4 ghz for a smoother gaming experience without to much more added heat.
Where this added heat comes in is the bios settings are usually at least 25 percent wrong. And that 25% is huge because of the settings they have wrong to start with.

And I have always stayed steady as to the difference between bench marking and gaming. You can not really compare the two. The only bench mark that can be considered a crossover between the two is 3dmark11.

And you do not see me advertising to other forum member's to buy only socket-ed cpus. And I already stated that once a BGA cpu surpass what ever cpu I'm using at the time, I will then switch and upgrade.
You have quite a lot of preconceptions about me that don't really seem to be true my friend. Although that bench marking part you get a 100 percent though.

 

I wasn't running on any preconceptions about you other than you have stated yourself, the benchmarking one is it, nothing else.

I was continuing the distinction between what can be expected between a 95w and 45w processor.

Nothing else was implied.

 

All good @hmscott then.

Let me ask you....Is that 45W cpu hard coded to that?

Because a 95W cpu can be made to run far higher than that.

 

Also, those chips at stock that are 95W range often run lower, like 65-75W. After proper volting to the specific chip, you can get a good overclock before reaching the 95W.

Yeah i dont think my processor exceeds 100W @ 4.5Ghz.

 

Mine is at 70W range at 4.5ghz. So...

Effectively yes, within a small twiddling range the Haswell / Broadwell 45w CPU's are locked to their safe range.

It wouldn't take much to eventually push them into thermal throttling even a little over their power limit. There just isn't enough headroom designed into the system - because 99.99999% of the users won't push it that far.

As a technical hack, probably possible, but I'm not interested in taking my "soldered" CPU in my $4000 laptop, into the "Danger Zone"

It's inappropriate behavior for the device's intended usage.

If I need to do that kind of work, it'll be in a project requiring testing those limits to destruction, and a budget for failed components will be anticipated.

For my personal gaming use, I'd rather find comfortable maximum tuning limits that don't include pulling my equipment apart to replace a failed component, or replace cooked thermal components.

I don't miss in the 45w CPU what you want to imply is essential and available in a 95w CPU.

And, if I don't miss it, being able to understand what it offers, something I'm not interested in spending time pursuing, then it's likely 99.9999% of the people looking for answers from you and this group as to which laptop / CPU to purchase, won't miss it either.

Having said that I may end up with a 95w CPU laptop, it's gonna take some time to see how these new laptops perform. There are lots of cool new laptops coming over the next few months, updates to first releases too. No rush.

 

Hmm should be around the same i guess, i have seen mine spike to 110W but think that was at 4.8Ghz or 4.9Ghz.
Specially after under volting, 6700k barely even touched 85W+ @ stock.

 

Yeah, 112W was no where near enough for 5+ benching. I've seen it go over 120W, but unless you are extreme on benching, you won't hit the W spec at all!

Sounds like what you're looking for is a P775DM3 with the single 1080 and 6700K. $300-$400 less than the P870DM2, and takes the 120Hz panel

 

Yes they are hard coded, I was able to get into the GT80 full bios menu and you could change everything and the cpu completely ignored anything around power. It was a total waste of time but nothing ventured nothing gained right.

Didn't @Dufus come up with some hack to unlock power limits on Haswell? That's why I left open the possibility of doing the same on other generation CPU's.

 

This is false for the 6820HK and 6920HQ, and maybe the 6820HQ. The first two can maintain power draws even over 80W and clocks of 4GHz indefinitely as long as temperatures remain under control.

 

No skylake mobile CPU (except possibly the 6700HQ? I can't find a user to ACTUALLY make the 6700HQ pass 45W believe it or not, it's just that bloody slow) is locked to 45W by default.

Manufacturers like MSI have been seen locking their CPUs to their base TDP limits under extended stress amounts, but Clevos and ASUS and other models have been noted to surpass that limit indefinitely, indicating it's MSI's BIOS or EC configuration that prevents it.

This isn't the same for Haswell/Broadwell which, unless you have a very rare 47xxHQ chip that I theorize was a 4710MQ they repurposed after discontinuing the MQ line, cannot pass 47W TDP for extended periods without hacking the EC to tell the processor it's drawing less than it actually is (ask @ryzeki about this working) or use Throttlestop's Powercut feature (I think that's the name) which does essentially the same thing, but can be buggier than a simple EC hack. Ironically this proves that they are not physically incapable of pulling over 47W, but that Intel simply desired to lock them down deeper than BIOS/EC level on purpose.

 

That's good news, that's the first I heard of this. Did you do it yourself? Links?

80w seems a bit more than the cooling can handle long term. Would love to see some more details.

 

There was also an exploit on early skylake microcodes, which has been closed with updated microcodes...

So Clevo with 6700k or msi with 6820 considering I prefer the MSI Chassis

 

definitely the clevo, you'll get much more for less money



btw, is the HDMI 2.0 and displayport 1.4?

 

Does anyone know if XoticPC will support Prema's Bios (when they are available) for the DM3? I know Mythlogic will but I don't see anywhere on XoticPC's website where they state it. I have decided to go big and get the DM3 with 1080 SLI. My main usage will be gaming and I know a lot of games don't support it, but it will be nice to have. An early christmas present for myself.

 

It's more or less the same price
With 1080 Single GPU Configuration

 

I believe he was working with throttle stop aka Uncleweb to work in some additional functionality of trickery but it didn't work in all cases after the later haswell releases if I remember correctly.

I believe @D2 Ultima has a thread where multiple users confirmed it. I also tested it myself in my GT80S with the 6920. I hit around 80C at a steady 77W with the max fans button active IIRC.

 

No go on the Prema Bios and XoticPC. So I will have a powerful PC that is gimped if I get it through them. They are about a 150 cheaper than the competition so far on a DM3 with my configuration.

 

They are currently not a Prema partner which means you won't be seeing the BIOS from them anytime soon.

Unless something changes and they partner up with Prema I'd suggest choosing a Prema Partner reseller such as HIDevolution in the US. (I'm assuming that's your location.)

 

No way to get the new T-Heatsink though.

 

Thanks for speaking up!

 

At this point in time, XoticPC will sell the Sager version of the P870DM3. So, only if Sager becomes a Prema partner would you get the BIOS.

See https://biosmods.wordpress.com/partner/ for a list of Prema's partners.

 

I do, this is correct.

 

Sager now has the P870DM3:

 

Thanks guys, found the posts I was looking for, pretty cool.

So, why do we need the 6700k ??

 

Don't have them posted. I also repasted with CLU, which made a huge difference. Settings were 90? mV undervolt and 4GHz at all core counts. Everything else was default. No mods are required. It's unlocked out of the box.

 

Thanks man, found what I was looking for, pretty awesome...

Why do we need the 6700k?

 

I'd buy from Mythlogic right now, if tax didn't kill the deal. Leaning towards LPC Digital at the moment.

Question: Is the PremaMod eventually released publicly?

 

Here is a teaser from my current build (specs in sig):

 

If we had something akin to an elephant in the room, is the memory in 1080 DDR5X or DDR5? I mean, for 1080 some sites report it as being X and some report is as not being...

# confused

 

Does hidevolution charge tax btw?

 

Prema bios were until ruined by one person. Now indefinite wait of not from Prema partner, which is worth any premium. Also mythlogic gets a modified unlocked Prema bios, not full unlocked. Choose wisely.

A long time ago, that used to be the case. However, recently Prema's work was ripped off by someone who took his changes and tweaked it to make it look like his own. The only sure way to get this right now is through a Prema partner. A Prema Partner will warranty the laptop and components as well.

You'll want to double check me on this, but I thought I saw that donations on https://biosmods.wordpress.com/ may also put you in touch with him to get the BIOS, but be warned, with some resellers if this is flashed, you may immediately void the warranty.

 

Id go for a perma autorised seller

 

+1, these laptops without Prema BIOS are no better than a crappy BGA low end laptop with 0 customization.

 

This is the best place to order it:

EVOC P870DM3-G

 

So which reseller offers/supports "full-blown" mods?

 

All of the others, I believe. Need to check for sure on Avell and dream machine, but can guarantee hidevolution and Eurocom!

I'm in the US btw.... Michigan.

 

HIDevolution is in California and they ship worldwide with the lower / fastest shipping rates and their global warranty covers shipping costs both ways if one chooses that warranty

 

So choose HIDevolution. If you send the laptop out of the country, the government can legally duplicate your data. I personally like privacy (nature of my profession - confidentiality for clients is mandated by the profession).

Can confirm NYC people not getting taxed when order from HID?

 

I am not sure, I hope @Donald@HIDevolution can answer that

 

Anyone out of CA , dont think will be taxed.

 

@bloodhawk @Mr. Fox

Vivian from HIDevolution told me the new power adapters are a bit longer by the way, so I'll keep them in the build rather than removing them to save a few dollars just in case
