Hello guys,

What do you think are Acceptable Memory Voltage for HD7970 in the long run?

Just got my first hd7970 and default memory voltage is 1.6v, what do you guys run on the memory voltage?

thx thumb.gif

Guys I'm wondering, what is VDDCI voltage. Have to touch it?

all i have needed was 1.6V but i beleive upto 1.7V should be the max you can go but i am not sure i would unless i have good cooling, but thats just me lol

Cooled my old 2500K at 5GHz / 1.5V without issues smile.gif

H100 is a waste of money :l

I know you mean well, but it's personal preference. It does the job and I don't want clunky CPU air coolers anymore. wink.gif

An excerpt from an old R6850 MSI document I found:

"VDDCI controls the voltage of PCI-E on VGA card. When increasing the PCI-E clock on the mainboard, users can increase the VDDCI voltage of VGA card to get better stability."

So there is a VDDCI setting on mainboard? Let me check
post #23067 of 38721
I don't think so on the main board, although motherboards vary.

What I think this is for is if you were to overclock your BCLK on your motherboard, raising VDDCI on your graphics card would give you better stability since the PCI bus frequency is derived from BLCK. Increasing BCLK not only raises CPU frequency, but also PCI bus and memory. Most people just leave BCLK at the recommended setting of 100MHZ, but a lot of the LN2 people like to overclock the BCLK, so the VDDCI setting is mostly for them.

sorry i cant be more helpful. i am sure it is a fine card.

Hi Mega Man,

Thanks for your reply smile.gif That's fine at least you tried smile.gif now go get some rest smile.gif
I know i should have waited for the vapor x, but i wasn't sure when the shop had stock again... Until now i saw a great improvement from my old graphics card... but any other opinions would be nice smile.gif

Thanks for this post!

I recently bumped up my BCLK and was wondering why my graphics card suddenly became unstable.

Do you know where to find the VDDCI setting?
