no luck here either, even upping it by 0.2 Mhz crashes my system

nope, no delidding yet but as i said before, those 4.8 Ghz clocks were stable without throttling in firestrike but i have no idea how stable they actually are! ill have to do further / proper testing for that...

oh yes, undervolting 980M would be brilliant indeed

sounds like voodoo @Khenglish did u at least get the control back after resetting the value?

isnt there also an option to set that spread spectrum in the premamod bios? maybe one could set it to a smaller calue to have less fluctuations

have u tried changing the bclk speed in the bios? its in the advanced / intel icc section

also try and flash back to the stock bios to check and see if its really due to the premamod or not.

try 1/2/3 sticks first and check if u can boot

if thats not the case, it might just be a ram/system incompatibility, things like that happen sometimes...

it indeed does help temps, got mine undervolted and it shaved a few degrees off load temps. what didnt help though, was undervolting system agent/digital io/analog io

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

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?

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.

yep it was iirc altho i have no idea how stable it is at that setting, it was just sufficient for that firestrike run ive only tested the cpu up to 4.5 ghz primestable at a VID of 1.16V (which was also my thermal limit)

i could possibly get it stable at 4.9ghz, but 5.0 is only good for validation i think. havent played around much at 4.5ghz+ yet though....

funny, that was exactly what was going through my mind, thats why i was wondering if he was on an alienware

lol, i still remember my desktop from way back barely breaking 9000 points in 3dmark06, and now its being trumped by an igpu loving this haha

Sent from my Nexus 5 using Tapatalk

are u able to use the 330W brick to its full potential?

also, what kind of oc are we talking about?

what kinda machine are u sporting?

hm, isnt it possible to use 30/40 pin cables in a 50 pin connector? at least i thought it was...

isnt that tool officially supported by asus?

Sent from my Nexus 5 using Tapatalk

depends how u implemented the gpu oc if it was just a software solution like nvidia inspector/msi afterburner etc and its not set to boot with the system then u should be fine. if, however, u set those clocks in the vbios of the card then theyll definitely notice them

on his website

ill look up my comparison post again if you like. the differences in gpu load and temps werent that big, but valley had a slight edge.

funny, i compared heaven, firestrike and valley with maxxed out settings at max. resolution (2880x1620 in my case) and found that valley is the most demanding out of those three

no worries there those are crazy temps though, at least as far as the 980M in the ZM series is concerned. even overclocked / overvolted to the max. im barely breaking 70C in unigine valley at 3K resolution....

the thermal limit of the vbios is already at 87C....

omg, that mustve been a TERRIBLE stock paste job
