GPU crash and beeping

Hi NBR,

I found what I thought was a stable overclock on my 970M (+240Mhz on the core) which has run perfectly 24/7 for about 6 months now. I have since started playing Project Cars and I am having it crash to a black screen and this last time it started beeping. It was continuous until I forced the machine off.

Is this any indication as to what the issue at hand is, be it voltage, VRM overheating or is the overclock unstable now?

GPU core does not go over 67C with auto fans.
CPU does not go over 63C
Panel is OC to 100Hz

 

sounds like one of the gpu components without a thermal sensor overheating. have you checked the placement and contact of your gpu thermal pads? also return that overclock to stock and see if the issue still persists. if it doesnt, then youll know its one of the other gpu components overheating.

 

Thanks for your reply.

D2ultima has said the game in question being built with PhysX being heavily used.

Perhaps with high core usage and physx at the same time the VRM is overheating?

Any other component in mind which could be the culprit?

 

well, im no electrical engineer, so i basically just go the safe route and cover everything larger than a solder point on the GPU with thermal pads

 

Agreed, a full repad of the GPU with some good thermal pads, I use Phobya XT pads which are relatively cheap and good... Along with a repaste with some good ICD should solve your problems..

Hi! Sorry I was away from home. The OC was fine in winter, now come summer I guess it's overheating as pointed out above.

For now I have returned to stock voltage and working out what OC will work on stock voltage.

However I do want to change the thermal pads over as suggested to try have my OC back. Do you know what thickness to order?
Links are very much appreciated if you have a reputable retailer to purchase from.

 

I would get 0.5mm and 1mm and stack accordingly..

As for links, firstly where Are you located?

Edit, I see your from Aus... I got Phobya XT pads off ebay from a German seller but probably ezpensive to ship to you.. @jaybee83 recommends some Arctic cooling 6W/mK pads which are available more easily and show some better characteristics according to him, worth getting touch with him or seeing his Sig, has a thread on this!!

I had the Black screen issue with my 980M. Now I got the Phobya Pads but they transfer the heat too much compared to old factory pads adding up the total heatsink Temps raise faster & the cooling system needs to catch up too when we change factory pads to aftermarket pads, I strongly suggest you to do a hard mod on the Notepal U3+ which is fairly super easy & much rewarding.

Though I feel It's mostly due to the gimping of the Maxwell MXM Cards with the low VRM count since people who hard modded the cards can push it further to 1400MHz-1500MHz+ and stable. Also the VRM replacement can also result in positive outcome but significant effort and resources are needed.

 

I don't have the knowledge or equipment to modify the card in that way.

Are you saying after changing the heat pads the core temperature rises due to more heat being transferred?
When using auto fans on a hot 32 Celsius day, pushing my GPU at it's max OC the core reaches 69 Celsius.

Perhaps in my case the extra transferred heat is easily managed in my system.

 

Yeah, Hard modding card is not possible for many of us & Just letting you know about the reduced VRM count related to the OC potential and Stability.

Only a theory that the pads transfer heat faster than the stock ones, from the behavior what I'm seeing on AW17 (Gimped EC fantables on Haswell Alienwares), Although temps have dropped.

Yeah, You should be golden since Clevo machines have better cooling. Go for the pads also do a repaste fairly easy and no hassle solution.

 

My Clevo reseller did a good job of pasting my components it will be a shame to destroy their paste job to change the pads. (I have a shared heatsink so CPU paste has to go too)
But I have been recommended the 11W/mK Fujipoly pads that I may just go for over the 6W/mK ones. Perhaps my VRM's need the extra heat transfer ability.

 

The 11W/mK pads are not that much better then the 6W ones according to the testing done by Jaybee, its really not worth the extra cost.. The 11W pads are also not very durable.. So if you ever have to repaste, you might have to throw them away!!

^I second that, Also to add Clevo HS are not that precise when it comes to the fit. That's why most of the resellers offer ICD7 to minimize it. The Phobya ones I use are already hard but not that like of Fujipolys.

 

The Phobya's can be reused however the 11W ones will be really soft and break so one trick pony..

Thermal paste wise, ICD is the best IMO, it just works for quite long without pumping out lol!

check out the link in my signature for more data on the thermal pads i can defo recommend the arctic cooling 6W/mK pads as the best solution for price per performance and reuseability!

Thanks Jaybee, reading in to it now.

Edit: Any idea on what size sheets to purchase for a single GPU thermal pad replacement?

Many thanks

 

About 120X120mm should be enough but let Jaybee confirm...

hm....lemme check my older 980M repadding posts on that, i mentioned how much thermal pad area i used up there for a complete redo....

edit: ok, so for a total gpu and cpu repad ive used about 6000 mm² at a thickness of 1 mm, that should be sufficient if youre careful in measuring up dimensions and cutting the pads to exact specs

right now im using a mix of 1mm arctic cooling 6W/mK pads and 3/4mm Phobya Ultra pads. moved away from stacking up pads towards using the correct thickness right away.

 

You used 2cm x 30cm of Phobia pads? With 7$ per 20x120mm it's like 21$ of pads. Are you sure?
edit: fixed my calculations but still... and price is optimistic.

 

yep yep, very sure. i checked my emails: i had ordered two sheets of fujipoly 17W/mK pads with dimensions of 60 x 50 mm each at a thickness of 1 mm. thats 2 x 3000 mm² and i remember it being EXACTLY enough to do a complete repad on the gpu and cpu side

 

Did that cost you $80? Those pads are crazily expensive and not worth it for the average person!

 

lol yes! theyre indeed very expensive, thats why i opted for the best price/performance ratio this time around and went with arctic cooling 6W/mK pads, in combination with phobya ultra for 3 and 4 mm thickness

at the time i paid 46 USD incl. shipping for the 6000 mm² fujipoly pads

in comparison, i paid 8€ for 1800 mm² Phobya Ultra pads and 15€ for a whopping 21000 mm² Arctic Cooling pads
