How are people GPU temps with the p650se with the 970m? I'm getting 62 degree celsius max on shadow of mordor, but htwinghut got 55 degree celsius. If I''m not mistaken, that is a pretty decent difference. I mean I guess I have the 4720hq while htwinghut has a 4710hq but still...

Its not a Haswell thing it's a Clevo thing. My desktop 4790k is set at 100 BCLK and stays at 4700MHz with virtualization enabled. I can't speak about other laptops but spread spectrum is not enabled by default on my Z87 Maximus VI Formula and doesn't cause any issues. Enabling it will actually make my overclock unstable. Haswell is much more sensitive to core frequency instability than previous chips - my 4.7GHz overclock is totally stable - at 4.7GHz. If I turn on power management instead of high performance, it will BSOD at some point when the clock frequency is going up and down.

@Prema Any word on a vbios that has undervolting on 980M? My cards run on the hot side and undervolting would probably help a lot, especially with my master that does 1321 at 1.062v. Thanks

Hes working on undervolting on the fly for the next update. Atlhough, I wonder how much these gpus can be undervolted without instability.

Just to clarify, if I use premamod bios it will not bypass the overclocking limitation for my chip right? For instance, I have a i7-4720hq and I can only overclock by 200 mhz whether be a single core or a quad core. If I have the premamod bios, the limitation will still be the same right?

it should, since all display output goes through the igpu in your case

Should I just undervolt the IGPU and Dynamic CPU Voltage Offset? Looks like you can undervolt the processor cache but I never heard of it helping temps.

if u used the core voltage offset for the -100mV u need to check both load and idle stability, since that offset will be applied to all cpu states (and thus different clocks with different voltages each). thus, leave ur machine overnight at idle and see if its still running the next morning. for load stability u can also use prime95 large fft test for minimum 20 min.

Alright thanks! Well it crashed while i was playing shadow of mordor. I went down to 90 mv seems to be alright for now ill need to test prime95. By the way, do you know if undervolting the igpu helps?

One of the reasons I want to undervolt the 970M in my p650se (i7 4720hq, gtx 970m, 1080p IPS screen AUO, 500 GB HDD 7200 rpm 7 mm) is so I can try to game with a 150 W razer blade adapter. Anyone thinks this is achievable? So far I did a 100 mv undervolt on my i7-4720hq and it has passed the 15 minute stress test on Intel XTU but I doubt that is enough to check stability. Anyone know the best way to test stability?

Hi,

My Clevo P650SE is due to arrive today (specs: 1080p IPS AUO B156HAN01.2, 4720MQ, 3GB 970M, 1x8GB 1600Mhz, 128GB M.2 SSD X110, 1TB 5400RPM). I would have liked the 2/4k screen- but didn't want to reduce the battery life any more (this is a priority for me).

My reasons for buying

• Portablitiy
  
• Power/gaming
  
• Expandable memory (RAM & Hard drives)
  
• Looks
  
• Screen size (previously owned the W230SS, but found 13.3" uncomfortable/small)
  

My premise- I need power when I'm plugged in (gaming) and just need more hours of batterylife when I'm not plugged in (I don't game on-the-go).

In order of importance- here are my reasons for being here/using the PremaMod)

• Unleashing/free'ing my laptop
  
• Maximize battery life
  
• Dual OS (Win 8.1 & Mac OSX Yosemite)
  
• Maybe- overclock my 970M (to 980M standards) but I may need a bigger power supply?
  

If anyone has questions about the laptop, I'm very happy to answer.

Does anyone have any advice on what I'm trying to achieve?

As someone with a similar objective (I have a similar build except I don't have a SSD in general and my HDD is a 500 gig Hitachi TravelStar 7 mm 7200 RPM drive), I would like to know how your temperatures doing various benchmarks (I've only tested Intel XTU so far) and I would be curious how your temps are. I doubt you have a kill-a-watt to check for how much watts are being pressed on Furmark+Prime95, but most people wouldn't do that test anyway since it gets abnormally hot.

Hi all.

Just wanted to check something. I just wondered if anyone has ran their p650se on a thin light weight 90w charger? The 180w which comes with it is just far to big for me to carry around me with as it weights the same as the laptop. I'm thinking about getting a small light weight charger for when I'm on the road.

I'm under the understanding that as long as I keep the draw below 90w there shouldn't be a problem. The laptop will just charge slowly and anything taxing like playing games ect off it is a no go, but I should be able to do office work / internet on a 90w charger fine.

As anyone done anything like this before on any laptop? I know it's not clear cut as I got a 60w charger by mistake with my macbook pro 15 when it needed a 85w. It wasn't till I took it back to apple thinking there was a problem with the changing that I found out it needed a bigger charger lol

I ran my mac for 6 months off a weak charger.

I'm thinking of buying a razer blade 150W charger for my p650se and I think the 19V and 7.7 Amps rating should be sufficient for travel and light gaming and not damage the laptop, but what I'm worried is the polarity since its not listed anywhere. Does anyone know the polarity on the razer blade charger? I think it should be the same as the 180 W chicony charger that comes with the p650se.

For undervolting (when the next update releases) will we be able to lower the voltage however we want or would it only be able to go as low as nvidia has it able to go in the vbios? Also, lowering voltage wouldn't cause the vbios to throttle/underclock would it?
