Games to test overclock stability.

Disco_P · 23 Aug 2014 at 08:42

Hi there

Right now I have a 780 sitting at 1241Mhz and 1.212v and would like to know if it is stable.

Reason I have my doubts is that after a few hours of BF3 or BF4 CTE I sometimes get a directx error. This could easily be just the games or some other part of the system so want to know of other games I can use for testing.

Games Library:

Many thanks

I found Sleeping Dogs to be a great PSU test, but not seeing it in your list of Steam games there (shame, it's a great game too). A few years ago I used to get random reboots in Call of Duty games when other games ran fine - turned out to be a PSU PCI-E cable arrangement issue - so those would be the ones I'd lean towards using from your list. Nothing else jumping out from your Steam, I'm afraid mate.

Sleeping dogs is there, between portal 2 and super amazing wagon adventure.

Crysis 3 and battlefield 4. Sleeping Dogs for memory stability

Sorry, when I first looked there was only one image. From your list then, I'd have to pick Sleeping Dogs, Crysis 2, Far Cry 3:BD, and CoD:BO2 as the most demanding, but I have no facts to back this up so very happy to be proven wrong by others.

Metro 2033 will give it a run for its money, its old but still manages to cripple some cards i believe.

Witcher 2 aswell

Farcry 3 is the best for core testing, 3dmark 11 for memory. Games like Crysis 3, bf4 and sleeping dogs are also good for all round stability.

Another vote for SD's, if your oc passes SD BM, your clocks a good one-it's a card killer.

Witcher 2 I have been meaning to play, good game and a extra reason to play. I put in a hour whilst I waited for replies and had no problems.

I have no touched memory for now. I'll use 3DM11 when I get to it.
Hopefully Blood dragon will suffice in FC3's place (no interest in saving Jason McDoucheBag Brody's friends).

Shame I don't own crysis 3, I would like it such that I can finish the crysis storyline but cannot find it for less that a tenner.

Fortunately I have sleeping dogs on my Backup drive. Will have to download 2033 overnight, is there a benchmark type thing that you can leave running?

Try MechWarrior online, max settings.
Especially good when there are some intense close range brawls.
The light show makes single 780 slow down a bit, SLI seems fine most of the time.
Game is free and you can just jump into a trial mech and play with no problems, just don't read the team chat, there are some real jerks and kids there sometimes

You can choose how many times to loop Metro, and Heaven BM can run on a loop too.

Have you tried your local GAME store? I managed to pick one up for a fiver about a month ago...

Good - I will stick metro on a loop. I used heaven previously but found it unreliable. Ridiculous clocks would pass without any problems and then instantly crash in games.

"Location: Lake District" should say it all. People here have only just discovered wireless radio.

I'll bear mechwarrior in mind but it doesn't seem like my kind of game. Never been a fan of free to play - attracts more unsavoury folk and I would rather pay upfront a get the entire experience. Then there is the pay to win plague.

I found that for the Vram, the Metro: Last Light benchmark is good for getting close to where you want it to be, then in Crysis 3 when aiming a grenade, the aiming arch goes everywhere if the memory isn't completely stable. After adjusting for this I've never had issues with either my 670 or 780.

As for core clock I found on both my 670 and 780 that the Heaven benchmark will freeze, usually when going through the tunnel if the clockspeed is too high. I'm not the only one who has found this either. Again everything else runs fine.

Welcome to the forums man!

Unfortunately I own neither Metro LL or Crysis 3. C3 is on my list of to buy and play but I have no interest in Metro (I got 2033 for free from nvidia's facebook page).

Heaven was stable for an hour plus at 1280Mhz which is a good chunk higher than any games are stable at.

Well their online store seem to still have stock on the download version:

1241 MHz at 1.212v is quite likely to be borderline unstable and that'll be why you have DX errors. I found that with my 780 which was a reasonable clocker it would top out being game stable a couple of notches lower than that speed. Benchmarks it was stable until about 1267...

The other thing to note is that unless you have the BIOS on there which disables Boost 2.0 the voltage will be flickng up and down by 13mV so that can cause a clock speed to bomb out as well. The BIOS I used on mine had constant voltage forced as well in 3D mode.

I know that 1241 is near borderline. But which side of borderline is what I want to know. This 780 is a reference A1 card with 80+ asic and does clock really well (50mhz better than a lightning I had for about 3 days).

Using skyn3t's EVGA OC BIOS so no boosting and more forgiving power target (though it only gets to around 70%) and I know for a fact that the 1.212v is constant.

Rusty0611 · 23 Aug 2014 at 14:15

That's good then. It was just something to bear in mind if you had the stock BIOS on. I had no crashes in BF3/4 on mine but when I clocked it too highly for it crashed with the same error. I think you can deduce from that, that it is borderline stable only. Of course more testing never hurts

.

I ran mine at 1189/1700 24/7 clocks with 1.187v constant. It was rock solid. The extra 50 or so MHz I could get out of it wasn't worth the extra heat and noise IMO especially when it barely affected performance.
