Could anyone share their settings for a 4.6Ghz OC for daily use or something higher that works well on air with a delidded CPU? I did 46x on all 4 cores and a 41 on the chache ratio and a offset voltage of -20 but I am still getting some throttling. Step by step would be helpful. I tried the Guide that Phoenix has on the first page but the Bios menu is a bit different.


Thanks!

 

wow 1 week not on here and i'm already missing 33 pages , time to read i guess and @Phoenix have fun with your new NB bro

 

More voltage. Remember only a few pages ago I replied and told you standard voltage should be enough for 4.5ghz? So a negative offset and 4.6 is going to cause problems.

Try +50 offset and see if that sorts you're throttling out.

 

I did try on stock voltage but it would throttle and the temps where pretty high. I will try the +50 offset.

 

That user has it's title as alienware meets apple. Just imagine how high they regard BGA in this case.

 

Ok so I tried the +20 with voltage offset with 46x multiplier on all 4 cores and a 41x cache ratio. These are the results.


Still have throttling and high temps. I used to run at 4.5 on throttle stop with a x41 cache ratio and a -70 voltage offset and had no problems with temps or throttling. I don't know what I'm doing wrong. Do I have to set up power limits on the Bios?

 

You are temperature throttling.You need to reduce your temps.

1. Were you using max fans during those tests? If not try this (FN + 1 no /off )and see what the peak temps are.
2. What thermal paste are you using? Do you have CLU on your CPU after the delid?

 

I was using max fans FN + 1

Using the liquid ultra HIDevolution applied with the Silicon Lottery.

 

Basically you're being thermally challenged.
If you reduce the voltage it sounds likes you're clock throttling.( -80mv isn't enough for 4.6... or 4.5 for that matter.)
Then if you give it more juice you're thermal throttling.

Unless you want to start getting into the OCD side of things like polishing Heatsink's / Heatspreaders etc you might have to temper your expectations and shoot for 4.4 -4.5ghz.

 

hit me up on Skype d00d

 

What a champ!

 

Could any of you all share your advanced settings with the Prema Mod I am currently running 5.0 stable (7700K) at +25 voltage offset, Voltage limit 1 & 2 bumped up to around 130 watts, Memory 16-18-18-43-525 (Voltage 1.25). Are there any additional settings I should change from the stock settings for better performace and lower temps. Also, Would I be better off finding the exact vcore than tweeking with offset? I dabbled with the stock bios voltage and it seemed to make 0 difference between finding the exact voltage or using adaptive (temperature/performance wise).

 

Once you have UEFI/CSM, you only have to disable secure boot and change video to legacy to get Windows 7 to otherwise be UEFI. Unless magic happened and no longer need to do video legacy, I'm confused...

@ajc9988 yes, I'm well aware of this and it is what was done. These options are not available on the stock BIOS but are available on Prema's along with the rest of the fun options available.
@steberg

Here's a modest overclock on my P750DM2 with a delidded i7-7700k to 4.7GHz with a -100mV undervolt (default like this on the Prema mod, but the OC isn't) running AIDA64 without TDP limit or throttling. This is also with the "automatic" fan profile which @Prema seems to have tuned to ramp up more gradually with less extreme steps and actually seems to do a good job of keeping things reasonable. Also the EC doesn't throttle like the stock one does.


What should I try out, any suggestions to push this?

 

-100mV on a 4.7GH is an insanely low voltage.

on my silicon lottery 6700K, I just leave it at stock voltage and it doesn't overheat more than 85C

when I do want to bring the heat down, the lowest I can go is -20mV

sure, -30 or -40mV might pass an AIDA64 stress test, but in gaming or even opening more than 25+ browser tabs at once in Chrome causes a system rreboot/crash

 

How about four 330W adapters at the size of two?

Ran into this behemoth: Turnigy 1200W 50A Power Supply Unit ($208).



The single-1200W port is limited to 50A, but it should be doable to use the full 1200Ws since the components on the mb's DC-DC circuit are rated for 25V. Whether it'll actually be possible to use all that current and not cripple something on the board is questionable ... the four inductors are the limiting factor, being 'only' rated up to 800W and Prema would have to find a way to fix that 480W firmware limit first:

But even without upgrading the inductors and setting it to the stock 19.5V would still output all the board can handle without requiring three 330Ws. Size of the thing is about twice that of the Delta, it costs about the same, but at 3-4x the power potential. Plus, it has active cooling and direct watt + voltage monitoring, so no need for a kill-a-watt gizmo anymore.

Only thing is modding the plug and, out of precaution, removing the voltage control button after setting it to the desired voltage. Wouldn't want to risk inadvertently setting it to 30V during transportation or brushing against it while it's in use .

The 'Specs' tab mentions different dimensions than the 'Overview' tab, but upon inquiry HobbyKing stated that the latter is correct. Perhaps the other one is for the shipping package.

 

This OC hardlocked about 30 seconds into a RealBench stress test

 

yeah too much of an undervolt man. as Mr. Fox says, don't be stingy with voltage

try -20Mv or 0mV (just stock voltage)

if it overheats, repaste with IC diamond using the X Cross method

The X Cross method is the best in my experience as once the heatsink is fitted, it provides the maximum coverage with the least air bubbles

 

@t456 We pulled about 820W max in one of our (internal) tests from a P870
Eurocoms 780W Adapter has a 900W peak rating, so it should get us a large part of the way until we reach 'total nuts territory', but I am afraid we will get there eventually

 

System will crash if the voltage was too low, not throttle.

 

true, power limits need to be raised along with the current limits, that's IF one is on the Prema BIOS. If they're on the stock BIOS then say bye bye to overclocking

 

If it's too low it certainly will. I'm thinking it's not quite low enough for a lockup/BSOD. Under those circumstances with Adaptive voltage the clocks can fluctuate and not hold and be perceived as throttling.

It could very well be something else...

 

Thats why, i always tell people to tests overclocks under the high performance power profile. The moment the voltage high the right "gap" the clocks will settle. If its too high, they will jump around.

 

You can test this yourself by spinning up a load and decreasing voltage in 5mV increments. I've never seen anything resembling throttling before it hard locks.

 

In my experience, there is a gap with voltage where it won't cause a BSOD, but it isn't sufficient to keep the system going. At this point, it generally causes black screen shut offs.

On the GPU it's reversed; slightly too little voltage will cause a driver crash and way too little voltage will just reboot the damn PC. I once applied a +262MHz core OC and +500MHz OC on my 780M and hit apply forgetting to adjust voltage; my PC instantly rebooted xD

 

I like where this is going though

 

Who all is sitting at their laptops today?

 

Me

Dont have the 7700k popped in atm though.

 

6700k?

 

yes, I have no clue which he keeps switching between the 6700K and the 7700K

 

Yep, the second one is in the desktop. And the first one, well we will know where it is on Tuesday

 

7700k's are for other systems. He hasn't actually bought one for his laptop....yet.

 

Bloodhawk soon will launch his own Silicon Lottery company to sell binned CPUs called the BloodHawk Lottery of Kaby Flakes

 

His will be called BloodHawk Kaby Bakes edition. You know, we don't want to name infringe.

 

I'm at work with mine for nine more hours (6700K). Single AC(330W) doe.

 

That would be fine.. We would only be doing cpu testing anyways.

 

Technically I am, but I don't think I can be of much help xD

 

This would be for the 6700 and 7700k's

 

What did you have in mind? I'm limited to max fans with 21C ambient, so can't do anything too extreme.

 

If I run a CPU test on my P870DM3 with a single power adapter, the power adapter would shut down within a few seconds until I plug it out of the wall and re plug it in

 

Just going to do some voltage testing is all. and to see if you can even run something simple like google chrome or internet explorer

Don't know what was going on with yours, but it is not suppose to do that. CPU does not pull enough to shut the PSU off on a 330W PSU. I have gamed on a single PSU before.

Edit: To clear up some confusion though....If you are over clocked and don't have enough or too much voltage....Computer will reboot or go to bsod.

 

maybe because I was trying to fun Fire Strike

 

Did you disable SLI before doing so? I can game perfectly fine and benchmark a single 1080 + overclocked 6700K on a single 330w PSU

 

yes sir

 

And both PSUs do this? I don't know what else could cause the PSU to shut down with only a load on the CPU.

 

maybe because I am using the PSU from my previous Eurocom Sky X9? the 2 new PSUs that came with the laptop are at home and I have that third one in my backpack always

 

Naw that shouldn't matter. At work I use one of my previous 330w ac adapters and I've been doing so for a long time without any issues. Only time it ever shut off was once when I forgot to disable SLI lol

 

anyway, not really bothered about this as I want to sell my laptop but no luck so far as I've posted it for 5999 USD on eBay with a min selling price of $5300 USD

 

Oh so you are going to sell the P870DM3 completely?

PM me

 

Yes, if you spec it out on HIDevolution's site, the price is above 6K, PM sent
