Hmm, alright. I guess I'll see how it works out with just the water cooling. Thanks.

Hey guys, I picked up the GTX 1080 FE (used) last week and it's been really awesome. But when overclocked, I noticed a lot of the power throttling going on, causing the core clock to rapidly fluctuate. Now, after a bit of Googling, there does seem to be a fix - the power limit mod. Now, there's a video by Der8auer showing exactly how to do this (applying liquid metal over a shunt resistor allowing more voltage to pass over than resistor - shorting it). However, in addition to shorting that one resistor in that video, there are others who say you need to short two other shunts (both labelled 5M0) as well to really benefit from the mod. Can anyone who's done this confirm this for me please? Also, I will be swapping the stock heatsink with a Kraken G10 and a H55 AIO cooler (with aluminium heatsinks for the VRM and VRAM). The guys over at r/nvidia and r/overclocking on reddit say that I shouldn't even dream of doing anything like that because I'll supposedly brick the card the moment I try any sort of mod. So it would be very helpful if I could get your insights as well. Any other tips, tricks and advice is also welcome. Thank you.

Oh, okay. I guess that makes sense. In that case I think I'll just leave voltage alone for now. I'm satisfied with the performance of the card at it's current clocks. Plus, given that I play at 1080p, it should be fine. Maybe in the future as games get more demanding, I'll look into flashing a custom bios. Thanks. I'll give it a day and see if anyone else has a possible solution without flashing a bios, if not, I'll mark your reply as solved -
Hmm, perhaps. Though upon further googling, I see this is a common problem for Nvidia 900 series GPU owners. A lot have said that their GPU voltage drops at load. I was just hoping someone here might have come across this problem and has a possible solution.
-
Do you reckon that's why the voltage is dropping? Due to not enough power being available?

So I recently picked up a Palit GTX 980 Super Jetstream, replacing my 770. So after trying out the new card on The Witcher 3, Watch Dogs (I can FINALLY play this without stutter!!), as well as Firestrike, I tried to see how well it handled overclocking. The card is factory overclocked to 1203 MHz at core (1303 boost), and memory is at 7200 MHz. So I saw that without touching voltage, I can go +150 on the core clock (Afterburner), giving a core clock of 1353 MHz and a boost of 1453 MHz. So naturally I started tinkering with the core voltage following that to get some more out of it. I did the usual 10mV increments, but while testing the card on the new voltage, I noticed if the voltage is over 1.225V (e.g. 1.25), it drops back to 1.225V within minutes into the game/benchmark. This leads to artifacting and also CTDs i.e. unstable overclock. Powerlimit is set to 125% in afterburner, with temp prioritized at 85 degC. Memory overclocked to 7500 MHz. So any suggestions to why this is happening and how I can fix this? Any help would be greatly appreciated.

I was expecting a bit more from the 970 Extreme, but then I realised that all the cards are overclocked, so in taking that into account, it faired quite well.
-
Yes that's a brilliant case too.
-
Seems like the Phanteks cases are a popular choice. But why is the Phanteks case better than the obsidian 750D? I'm not saying its not, just would like to know why. Thanks.
-
Well, according to their website and various other retailers, the Luxe is stated as a full tower. The primo is just the premium version, sort of like NZXT's Phantom 630 and 820.
-
So I will be upgrading my PC case soon, and am looking for a full tower case with good airflow, a good overall design, support for future water cooling, and general durability that'll last me at least 5 years. I'm having a hard time choosing between the Cosair Obsidian 750D, the NZXT Phantom 630, and the Phanteks Enthoo Luxe, and was hoping you guys can help make my decision easier. Other suggestions are also welcome. Any and all help would be greatly appreciated. Thanks.

I would recommend the NZXT Phantom 630 ($190 AUD). It's got great cooling with 3 included 200 mm fans and one 140 mm fan. More fans can be added, as well a variety of options for watercooling. The Corsair Obsidian 750D ($210 AUD) is also a great case, but doesn't look as good as the Phantom 630 (my opinion). The 750D is also quite big, which means plenty of room for airflow. However, if you want a case for pure air cooling bliss, I would suggest Corsair Carbide Air 540 ($190 AUD). It's a bit bulky, but has brilliant airflow; direct front to back uninterrupted airflow.

Water Cooling GPU with AIO Liquid Cooler
Sourav93 replied to Sourav93's topic in Custom Loop and Exotic Cooling
Hmm, okay. I'll try and remount the heatsink and see if the temps improve. When you say replace the thermal pads on the VRMs and VRAM, I am assuming you mean putting new pads on? -
Water Cooling GPU with AIO Liquid Cooler

I've seen the installation of the Kraken G10, and I don't think a not reference PCB will be THAT much of a problem. I mean, my GPU is just over 11 inches, but a there's a overhang of the stock heatsink. If I were to go for a custom loop, I'd probably start with a Swiftech H220; I know it's not really a custom loop, but it'll get the job done I suppose. And yeah, waterblocks are usually very specific, so that's another thing to consider with a custom setup. And since I recently upgraded (April 2014) from a 570 to 770, I don't think upgrading again will be wise. 95% of the games out the can be handled really well with the 770, plus mine's factory OC'd. It's just the temps really. Lowering them would also give some more room for additional overclocking. In Furmark, on stock settings, the card throttles at 80oC. With the temp limit increased to 95oC, it can go up to 86oC. In Bf4, temps have gone up to around 82oC, but they usually stay around the 75oC mark. I clean my case and components weekly with a canned air duster, and the fans seem to be spinning fine. I've attached an image of my current fan curve (default). Just fyi, my card is factory OC'd to 1150 MHz, boost to 1202 MHz guaranteed. Though usually goes up to 1241 MHz.
