Title: Is this normal : current problem ? Post by: heretolearn on February 01, 2014, 02:06:20 PM Hi,
One of my cards sometimes fluctuates the current level shown in GPU-z The normal current lievel VDDC Current is 93-94 A (Amps). However the card sometimes falls to 76-77 A for a few seconds and comes back to the level earlier. Is this normal ? Or it something wrong perhaps with my PSU ? PS: I recently had one of my burnt cards replaced so don't want the same situation again. Title: Re: Is this normal : current problem ?

PSU : Silverstone 1200 W Cards : 3 Title: Re: Is this normal : current problem ?

Will do and update. UPDATE : GPU load remains stable at 99%. What else could be causing the fluctuation in current ? ??? Title: Re: Is this normal : current problem ?

Try switching the PCI power connectors of the card and see if the same card that keeps getting his current drop. Title: Re: Is this normal : current problem ?

Hmm nice suggestion ... will do it the next time I power my rig downn in the morning and update. Meanwhile still looking for any other ideas/suggestion as to why this might be happening. Title: Re: Is this normal : current problem ? Post by: heretolearn on February 02, 2014, 10:47:48 PM Ok now the VDDC voltage seems to be fluctuating !! Is it the power supply ? Should I continue mining ?

The GPU load is fluctuating after kept it running for a day. Someone please help. I don't want to burn/damage my cards. |
