Is Heaven still valid for Maxwell cards?

[Michaeljcox24]

Im running a watercooled 980 at 1.262 volts and 125% power limit with +250 on the core and +400 on the memory. Core never goes over 40 degrees, no matter what I throw at it. Im 2nd place at the moment in the Monster Hunter benchmark scoreboard with this card.

I got AC Unity free with it, which is actually an OK game once its patched up. Since I've had it though, Ive had the ACU.exe crash quite a lot, which doesnt show up as a card failure until you look in Windows event viewer.

On my old 690, I used Heaven as the frame of reference for stable gpu overclock. It would die at +120 on the core. In comparison, this 980 overclocks like a monster, like all the reviews says they do.

Heaven is rock solid stable on +250 and +550 on the memory. As is every other benchmark I throw at the card. The ONLY benchmark that shows up errors is furmark. Even then, the card hits 43 degrees max.

Is Heaven still a good guide for Maxwell? Valley runs fine too. I'm wondering how relevant it is for mondern demanding games.

I could be wrong but wouldn't that be just another bug in an Ubisoft published game?
I'm sure I've heard of a few people with crashing issues.

Whats it like in other games. Cause tbh, every recent game that ubisoft has released has been a disaster. Certainly not the best of games on which to test any form of stability.

 

[Michaeljcox24]

Its fine in other games. But when you max it out, its one of the visually most spectacular games I have ever seen. When you look on event viewer, there is always the graphics driver crash a seconds or two after the unity executable dies.

Coincidence?

 

[setter]

Ive had that on event viewer as well, mainly bf4 and a known bug with it, (now fixed), bf4 exe crash message followed by an nvidia driver crash. Probably just windows way of reporting that the card is no longer running due to the application closing.

 

[Michaeljcox24]

Ill have to do further testing. Furmark was crashing at the memory clock that ACU.exe was, but heaven wasnt. Heaven was solid as a rock. As was Valley. Monster Hunter. Etc etc.

When Ubi are officially saying its all patched up and ok now, I want to be sure before I submit a bug report

I wouldnt reccomend furmark for testing gpu's, iirc all the big review sites stopped using it several years ago due to unrealistic loads, (it's like the haswell cpu equivalent of prime 95). When i had a pretty highly clocked 670, the clocks that were stable in heaven, valley, 3d mark etc would crash in games, (1320/7700 iirc) had to back of on the core to 1306 and 7500 for stable running in games. What about unity with the card at stock clocks, any issues?

 

[Michaeljcox24]

I only played it at stock speeds when I first had the game, and it didnt crash at all. Its quite demanding and responds well to higher clocks

I wouldn't use heaven or valley for stability testing.

Personally found ludicrous clocks will work just fine whereas I would instantly crash in other games.

My go to test is BF3. Just leaving it open at the spawn screen works as well as any other gameplay moment.

 

[facboy]

if you don't get the issues when you lower the clocks (or at stock), then your oc is unstable. end of.

 

[Telecaster]

Same here, but only on a 750ti, Heaven and Valley will run monster clocks rock solid but I get artifacts and crashes in game.

Never been into battlefield, are there any other benches out there that are up there with furmark in terms of stability testing. I saw one yesterday called Catzilla, but when I downloaded it, you had to pay to get 1080 res. Meh.

i found heaven rubbish for finding stable clocks, i much prefer 3dmark

I recently had similar problems with Black Flag where it would crash with an executable failure which turned out was caused by the card. Could take anywhere between 30 seconds and several hours. In my case I believe it is the card as it happens in other games such as BF4. Heaven certainly isn't useful for testing stability as no matter how long I run it for it doesn't crash, same with Valley, the same goes for Furmark and OCCT. If it's just the one game then may well be an AC: Unity bug but try and try out other stressful games. For several months I mainly played BF4 and thought the crashes were due to the game as the other, less stressful games I played weren't showing problems, so try and rule out that possibility ASAP.

Firestrike doesn't crash either. Perhaps I need to try FS Extreme

You have to factor in that games utilise the CPU as well which puts extra strain on PSU and cooling, try running a CPU test at the same time as Heaven for a more realistic stability test...

Either way there's no definitive stability test that's 100% reliable, a stable overclock shouldn't crash in anything unless it's a software bug, if it does you're not stable.
