Gigabyte GTX 780 ti GHz edition game crash

[taimur_111]

Hi everyone,

I just purchased the gigabyte 780 ti GHz edition 2 days ago, fresh installed the drivers (removing old drivers etc completely) and started to play around with the card.
Day 01:
Tomb Raider ~ No crashes
Crysis 2 ~ Crashed after 2 minutes of the game
Metro last light ~ Crashed after 2 minutes (multiple tries)
3D Mark futuremark ~ No crashes

I should have researched for this card as everyone is having trouble with Gigabyte's 780 ti and even 780s. But the problem is mine is not as severe as others.

Day 02

Tomb Raider ~ 1 hour game play - No crashes
Crysis 2 ~ No crashes
Crysis 3 ~ No crashes (yet disappointed at fps 40 avg with everything high.... I don't know if this is what a 780 ti OCd should get?
Metro last light ~ crashed after 5 minutes
Heaven 4.0 ~ 30 minutes everything extreme etc no crashes or anything
3D Mark futuremark ~ No crashes

Since everyone either RMAd their cards or refunded. Now I'm wondering if I should do the same or nothing is wrong with my card?
Only the metro LL is giving me a headache

I had GTX 680 SLi before and yet no such problem in any of those. Metro LL running smoothly with 120 fps without SSAA

System:
Intel i7 3820 @ 4.5 GHz
16 GB GSkill aries @1600 MHz
Samsung Evo 250GB SSD
Gigabyte GTX 780 ti GHz Edition
SilverStone 1000w PSU

Which x79 mobo are you using with which cpu ? I was thinking to go for 4930k and get the 3.0 PCIE speed, what do you reckon

 

[i7Baby]

I'm using 3930k with ASRock Extreme 3.

If I could afford it, I'd get 4930k with ASRock Extreme 6.

 

[taimur_111]

your gpu is already enabled with pce 3.0 speed

 

[taimur_111]

^nevermind, i just read the 3930k and it has the revision 2.0 pcie :/ i thought it was 3.0

 

[i7Baby]

I only really use my two gtx670's for their cuda cores for video editing hardware acceleration.

 

[taimur_111]

try the hack and see the performance boost, I'm pretty sure the hack is not harmful, I was on it for like years without any issue. Btw, is the i7 4960X any good or how much better compared to the 4930k ?

 

[i7Baby]

10% better perfromance for 40% more $

[taimur_111]

I'll go with the 4930k then, will see how much performance difference between both 3820 n this.

Hi, Sorry I've ran into a small issue and thought to ask you for help...
I bought the 4930k and it is simply awesome! I OCd to 4.6GHz (gpu is still evga 780 ti) running perfectly smooth. I also bought corsair H100i thought to try water cooling. It performs better than my Noctua NH-D14.

Anyway the cpu was bought yesterday. I played games for hours without any issues. Today I thought to stress test the beast with Prime95 and OCCT. Problem is system crashes every 5 minutes in Prime95 Test and OCCT fails within 2 minutes with message: Core#0 Max value reached = 185 degrees (which is ridiculous and isn't even possible?) maximum I've seen my cpu temp in MSI AB, ASUS AI suit, RealTemp is 74 C. CPU idles at 26-30 C which is perfect. I'll post some pics.

Thanks

That's what Prime 95 is for - to test the OC. If it's crashing, you have to back off on the OC. Drop Vcore .05V

 

[taimur_111]

OCCT & HwInfo

OCCT now cannot run at all! just for 2 second and gives the error message of max value reached 🙁

I've never touched voltages, only increased the BLCK and the ratio thing to 37 and BLCK to 125 i think..

 

[i7Baby]

Your Vcore is OK. Your core temps are too high. Must be the h100 not working properly. Check fan speeds and pump speed. If OK, re-seat the block.

Why does OCCT say your Vcore is 1.45 but HWInfo says 1.2V? Check with your UEFI. Keep Vcore less than 1.25V

Thats bothering me, I mean temps never exceeds (when i monitor) 73-75 degrees. H100i seems fine i don't see any seating issue or anything, also the fan speed runs ridiculously loud and rpm gets to 2300 when under load.

I'll report back with UEFI Vcore if its more than 1.25V but just out of curosity (sorry I dont have much exp in here) is 1.25V too less for OC ?

 

[i7Baby]

Usually you can start to OC from 1.20 to 1.25V. Depends on the exact cpu (they vary).

more info on 3820 - http://www.cpu-world.com/CPUs/Core_i7/Intel-Core%20i7-3820.html Vcore range: 0.6 to 1.35V

 

[taimur_111]

I'm not using 3820 anymore got the 4930k. I really don't know how to work on with the Vcore voltage. In bios, there is CPU VCORE Voltage with 2 options, Offset Mode(Current) and manual Mode. At the moment the cpu is overclocked (4930k not 3820) at 4.445GHz and VCORE voltage is 1.404 by default like i didn't do anything. How should i change this to 1.25V ?

 

[i7Baby]

If its overheating then don't overclock it!

When you want to overclock look up overclocking guides for doing it first.

The H100i should keep your cpu to under 55C even under load. On idle it should be under 40C. If its not, then it hasn't been set up right.

Double check your cpu temp. Use your mobo UEFI.

 

[taimur_111]

I read some forms and many people's suggestion was to increase the multiplier rather than the BCLK (which was at 125 all the time). I changed that to 100 and the multiplier to 43. Seems pretty stable, Idling at 24-28 C and medium load is 45-55 C. With full load using prime 95 it gets maximum 66 C which is much better. Only the OCCT is failing. I guess there is something wrong with OCCT as the failed temps that it reports is ridiculous (150 C) lol.

Thanks for your help.

No worries.
