GTX690 Lower GPU overclock after Haswell upgrade

post #1 of 4
Thread Starter 
Hello everyone.

I am hoping someone maybe able assist with this, for me, rather perplexing issue.

I recently upgraded from a 2400 + P8Z68-V LX to a 4770K + Maximus VI Hero. Everything is great with the new hardware, I am having good fun OC, the CPU will do 4.9 @ 1.35v biggrin.gif The GPU however, a Asus GTX690, will not go past +110% clock offset 1149MHz boost. Before the upgrade it would do 150%, 1201MHz boost, the voltage is the same 1.175v the memory offset dose not seem to matter if I set a 0MHz the gpu still wont clock past 1149MHz. Temps are good max of 48c GPU core, delta arround 8c, running heaven @1600p for 60 min.

Just to clarify when I say 'wont clock' I mean that it wont run stable. It reacts the exact same way as when I first started OC on my old MB. If I increase the gpu offset to 130 % say, it will run for a while but, under continued benchmarking or heavy gaming it will crash back to the desktop. IT was rock solid @ 150% before the upgrade

I have tried resetting the BIOS to defaults so no CPU OC which made no difference. I have also tried various voltage setting in the BIOS but being relatively new to this level of tweaking I don't want to push them without first knowing what they are doing.

The GPU will run at 1175MHz for a while, enough to run 3dMark, but it wont run stable, its like it is teasing me....... I have also noticed that the at higher than 110MHz offset during firestrike the GPU voltage is erratic even with KBoost enabled. I don't remember this happening before.

As you can see from the link below performance is good, so I am not complaining wink.gif

My limited knowledge leads me to believe that the card is struggling for voltage. Could the change from PCI-e 2 > PCI-e 3 be why?

Can anyone suggest any voltage, setting or configuration I can try?

thanks for reading

Well since you have a single GPU it runs at 16x pci-e 3.0 which has twice the bandwidth of your previous system. Possibly the card wasn't few being used at capacity on the pci-e 2.0 so it wasn't being stressed as much which allowed a higher over clock.

As for lack of power, your PSU is massive for your system so I doubt that is the case.

I also have the maximus iv hero w/ 4770k. But haven't tried to OC my GPUs yet. Have a pair of 660 ti cards in sli. i know they benchmark at stock a lot higher then on my last PC which was a i7 960 with pci-e 2.0.

Edit: meant maximus vi hero

Good point make sense. I never keep any of my benchmarks results from my old system but performance in game is massively improved. For example Tombraider, 40-70 FPS with noticeable and annoying stuttering, now its perfect never drops bellow 60 fps butter smooth. Am not 'seeing' a drop in performance so I guess I should just be happy.

I didn't mean lack of overall power from my PSU. I was thinking that PCI 3 may use move voltage so maybe increasing the volts to the pci-e controller or something like that might help. I have been through most if not all of the settings in the BIOS now and none seem to make much if any difference to the GPU. Maybe its a combination I have not hit yet or I am just way off the mark. The most annoying thing for me is not knowing why there is a difference



Thanks for your reply. thumb.gif

No problem friend, just remember this is just my best guess as to why you can't OC as high anymore.

As to voltages over the PCI-E, you only need to worry about those voltages when OC'ing motherboard speeds such as your bus. Have nothing to do with your actual GPU/Memory OC on the graphics cards. Those voltages are delivered by the 6-pin Molex connectors, and are controlled by the graphics card itself. The PCI-E slot would not be able to handle delivering that much power to the GPU, hence why you have separate power connections for the card.
