@Mr. Fox @GTVEVO

I don't understand how to set manual CPU voltage in the BIOS, like what is the value like? for example if I want 1.165V would I enter a value of 1165?

Also, what do you think is a good voltage for 42x4 or 43x4?

 

The best voltage is always the lowest that is stable for your chip.

 

Obviously, but as I asked, how to enter the value? since 1.165V for example has a dot after the first number 1 and like I'd want to know what's an average good starting point for the voltage for a 4,2 GHz on all cores.

Like I know my CPU is stable and cooler with an adaptive voltage and a -150mV offset. But what if I wanted to keep it at a static voltage.

 

I was asking myself the same thing. On the voltage override entry, it doesn't looks like I'l have like 1165mv if just put "1165" there.

I saw @Mr. Fox images where he was using like just "600".

 

Any reason you want to run 42 or 43 as opposed to 45 let's say? Aside from small fluctuations in clock mine runs at 45 with no crashing and good temps.

I have a bad overclocking CPU, I can barely get 4.2 on all cores stable

 

In all honesty for x42 just use Throttle Stop with adaptive voltage. Usually around -80mv should put you around 1.19 or 1.2 VID or VR voltage under load. Then test for stability and perf here and move up or down. Just take your time.

Using the static voltage is possible but using TS will be safer until you find your true core voltage which will be lower than your VID at the regulator.

right but what is the value that one would need to enter if he wants for example a voltage of 1.165V?

 

Yes 1165 mv = 1.165v

BTW, let's say one day my CPU goes bad, can I just go to any computers shop and buy a regular desktop 6700K and just replace it or is it some special 6700K that is used for laptops?

 

Yes you can, it's a standard 1151 socket. socket. Nothing special.

Adaptive voltage will keep you cooler under idle, it's best to use it if you can.

 

Yes!, in fact, if you want a pre-tested at highest speed 6700k, delidded even, you can get it at SiliconLottery.com - anywhere else?

6700k tested at speeds

On the p870dm bios adaptive or static still use vdroop and offest the same so the result in idle and load will perform the same VID. I have done lots of testing to work around the high idle voltage with cpu at 100 pct min.

Just be aware SL tests their CPU on 1.4v!. A voltage that probably wont be relevant to this laptop.

 

That's what I was thinking, how high of a voltage should one go on this CPU in a laptop?

 

They have been very helpful through the support emails, I am sure if you ask they will tune for your needs, it might cost extra, but it's worth asking.

 

It's a desktop CPU in a desktop chipset motherboard, I would think the same goes for the P870 laptop as for the desktop.

 

Its mostly depended on heat imo. Anything higher than 1.4v on desktop is close on the insane territory without liquid cooling. I believe thats what ASUS recommended as a maximum. I doubt you can get pass 1.3v without delidding and CLU though. Even if cooling is fine, I wouldnt run anything over 1.4v on this laptop out of concerns for the VRMs. @Mr. Fox any recommendations?

I can do 4.5ghz on 1.24v. I am happy with that. FYI, I noticed a huge voltage wall after 4.5ghz, like you start to need way more voltage to get 4.6ghz stable.

 

Yes the desktop 6700k I overclocked hit a wall, 1.4v netted me around 4.7ghz with some base clock tweaking but with a huge tower cooler it was getting hot.

 

I hate it when ISPs overpromise and underdeliver. Spending my night troubleshooting my wifi is not the idea I had when I came home.

Canadian ISPs suck so bad that I want comcast...

 

Has anybody pre-ordered the oculus rift CV 1 to try and test with this beauty?

I use my supplied router as a modem and then a high quality router to actually give out the wifi

 

Without prema bios, actually voltage is not the problem.
Current and power limit is the bottleneck of CPU OCing.
The stock bios of p750 and p870dm allows only very little power and current.

 

Hypothetically speaking, can this machine support a m5000m as display GPU and a Tesla m6 in the second slot using something like unRAID or even Dx12.
If possible we could probably even create our own wireless grid 2.0 VDI

Yes I was all over cv1 and had my order completed about 2 min after pre-order was open. March delivery expected.

Yes we discovered this back in Oct/Nov right after release. There is an issue with the stock EC firmware. I would have thought they would have fixed by now. The older firmware doesn't have the problem so FYI.

Sent from my LG-H901 using Tapatalk

 

Maybe they did it on purpose, in which case it may never be fixed except with @Prema Mod BIOS. Clevo has always been of an anti-overclocking mindset and selling systems with horrible stock system BIOS. Their machines are only good with overclocking after @Prema steps in and fixes all of their terrible firmware messes. Even the almighty P570WM that @johnksss @Kpaxx, myself and others are rocking is pathetic with a stock BIOS.

 

Right and I agree as it wouldn't surprise me at all, I was just always assuming they would fix after someone joining our thread quite a while back stating they had a fix and it was just in testing. I want to say around the December timeframe, it's a shame for sure.

Yeah, I think that was @Larry@LPC-Digital if I remember correctly. And, it may have been an update from Sager only, not something from Clevo. Hard to say. You'd think Clevo would want their flagship product to work correctly using stock firmware without an overclock, but it doesn't seems like it.

 

Hi, using Throttlestop 8, what settings exactly should I change and what #s should I set them to to get a -120mv voltage on the CPU? I never used this program before and I' M not sure what I need to lower on it with a Clevo's 6700k. I'm not familiar with voltages and timings and whatnot and I don' t want to accidentally fry anything. Thanks.

 

I know I brought this up a ways back and I scratched the idea... but here I am again with sli questions. Just so happens I sent my Myth machine back to swap out the 2. 256gb 950 pro ssd's for 1 512gb 950 pro. Long story short.. the Raid 0 was causing too many issues. So I decided to drop it and run a single drive for the OS. I will be getting it back with the latest bios and all that good stuff.

Ok so now on to the other side... since the laptop is back at headquarters... I have an opportunity to swap out my gtx 980 with 980m sli. I was overall pretty happy the with 980 performance. However there are still games that under max setting dipped into the 40-55fps area and I really prefer 55-60+. I have read a TON of horror stories on sli which is why I never went with it to begin with. However.. I also have seen some forum members have an amazing gaming experience with SLI, and with DX12 fixing most sli issues in the future it got me thinking. So.. I need brutal honesty here. Overall is the 980m sli going to be the better way to go? Or are the issues that come with it and compatibility just not worth the trouble. I am running windows 10 pro btw. I mostly want to hear from the gamers here that have the same Prema build/prema partner build. How has it been?

 

I like it. Waiting for Prema vBIOS. It really depends on how much you want to spend on making sure things work and how much you are tolerate certain games that dont support SLI.
Do you want absolute performance or consistent performance?

 

Well that's a loaded question because I want both. I figured consistent is better which is why I chose one. But it just seems like everywhere I turn people talk about how great sli works for this and that game etc despite the horror stories I hear. The part that I'm concerned with is what kind of tweaking is needed... And then if it absolutely doesn't support it I am back to one card which is not only weaker than the desktop variant... But it's the card I had in my alienware. Which would be like having no upgrade at all.

Now if it does work well overall... I can see absolutely loving the OC headroom and performance I get from it..

Well, how much it will cost you to get the 980m SLI? Also remember you can sell off the 980m SLi for your pascal upgrade, you cant sell off 980.

 

Anywhere from little to nothing actually. So not really a matter of cost. More a matter of 980 vs 980m sli. I just have to let Mythlogic know before they send back my laptop if I want to keep it as is or go sli before they ship it out.

Sent from my XT1580 using Tapatalk

 

I personally would go with SLI imo. You end up saving more money since you can sell off the cards off. If SLI works, you get huge performance boost. An overclocked 980m is easily on par or above a 970 anyways. Though listen to other people's opinion before deciding. I have my own preferences.

 

I would stick with the single 980 myself unless I was seriously considering VR.

 

You also have a desktop . For those of us laptop only, we need the extra power man!

 

I haven't used Throttlestop, only Intel XTU so I can't answer your question right now... Sorry.

 

What kind of "extra" tweaking is required for sli? Anything particular? How do you know it's working properly?

Sent from my XT1580 using Tapatalk

 

No I don't actually

 

I know i know Mythlogic doesn't support it yet(or anywone exept cybertron PC at the moment). But would you stretch your budget for the 980 sli if available before they ship it back?

Does anyone else have an ETA for this option to be available through more vendors?

The edit feature sure is handy . I wish you could do the same to PMs...or even texts and mails

I looked on the CybetronPC site and it looks like all the "Osiris 17x" will launch within the next 6 hours when the CLX portion of their site relaunches to coincide with an Egyptian holiday. Since I had to send my phoenix in for RMA to my reseller (Xidax computers) I may talk with them about exchanging the 980m SLI towards the cost of dual 980s. I've built up a good relationship with them and they have an option to order parts not available on the site so we'll see. If not, I could always sell the 980ms' in the future.

 

I've never had any issues with SLI and I don't understand the people that knock it. SLI performance is almost always superior. I have had trouble with 980M. If you get a good pair of 980M they are awesome. If you do not they suck.

Typically none required unless the game or benchmark is a poorly coded piece of garbage. A few now and then lack support so you just pretend you have a single GPU for those crappy titles and disable SLI. A few title now and then required setting AFR1 or AFR2 in NVIDIA Control Panel until driver updates fix the SLI profile, but is pretty rare and not often enough to be inconvenient. For all intents and purposes, I've had no real problems with SLI other that those occasional exceptions. The vast majority of the time you simply turn it on in NVIDIA Control Panel (set it and forget it) and it works automatically.

 

What do you mean by 'good' pair of sli cards. Could you please elaborate (sounds like a lottery )

Sent from my Micromax AQ4501 using Tapatalk

 

It is a silicon lottery for both GPUs and CPUs. Some overclock better than others. Higher GPU ASIC scores are nice, but not a guarantee of good overclocking. All the higher ASIC score does for the most part is allow you to use lower voltage for higher clock speeds. I've had GPUs with ASIC below 70% that overclocked like a banshee if you gave them the voltage they need and took steps to keep them cool with the higher voltage. The 980M SLI in my Panther works flawlessly stock or with a moderate overclock, but they are not stable enough at higher overclocks for me to do any hardcore benching. For that reason I put them up for sale on eBay so I can try my hand at getting a better pair of 980M cards that will handle a 1450MHz+ core overclock stable.

 

Interesting! I've heard of silicon lottery and its effects on overclocking before (I can imagine the odds are worse for sli), but what about stock SLI. Should warrenty lubbers and overclocking newbies (like me ) be worried?

Correction: I was thinking of the CyperPowerPC not CybertronPC.

Here is a link to the laptop I was remembering, one of many from them with 150w power adapters listed in the Full Spec:

https://www.cyberpowerpc.com/system/Fangbook_4_XTREME_SX-L_500_Gaming_Laptop

Spoiler

The one odd thing I noticed is all those CyberpowerPC GT80 like models have a 150w power adapter, including the SLI 980 model.

150w is no where near enough power even for a single 980m laptop, let alone 2 x 980.

Make sure your model comes with at least 1 330w, but for 2 x 980m/980 you really need 2 x 330w + adapter to run dual power 330w's.

 

I agree, but won't 1 330w be enough for 2 980m's at stock?
