Overclocking HD 7970 past 1.3V in MSI AB (4.0.0)

shorinman

So, frustration.  Can't figure out how to get afterburner to let me overvolt this card past 1.3Volts.  I'm getting a rock stable 1225Mhz @ 1.3 Volts, but feel like I can get higher!

 

Anyone know how to get MSI to let me go further than 1.3V?

Hang on cowboy! 1.3V doesn't look like a lot, but for a GPU it's really A LOT, the reason it won't go any higher is because you will possibly blow it up if you do that. Tbh i'm suprised it's still alive now.

overvolting a GPU is not the same as a CPU. If you want to oc it just for benching and want to start using the soldering iron, then you can push more voltage trough it. You can find tutorials on the internet, but if it is for 24/7 use, bad idea.

If you want my attention, quote meh! D: or just stick an @samcool55 in your post :3

ahhhhhhh. what temps are you getting? im getting 1775 mhz stable at 1.2 volts. a extra .1 volt is not worth the 50 mhz. let alone any farther. 

 

edit: and to answer your question, with my 7950, i have the unlocked afterburner that allows extra OC, and it wont let me go past 1.3. the only way would probably to flash a new bios. even then i dont know if its possible.

 

 

It feels sketchy to run the card at 1.2. your cutting years off your card running higher.

I've been running 1225 @ 1.3V stable, mind you not 24/7 or anything.  Only during heavy gaming sessions (games that are GPU intensive anyway).  Anyone else have any insight?

Can you provide any proof that pushing 1.3 volts decreases the card's life span, even if the temps stay below 70C?  (VRM might be a different issue)

Does using alternatives to MSI allow more voltage...Like MSI on the 290 uses ONLY +.100, yet Sapphire TRIXX software can allow up to +.200 to be added.

 

Look into NON-MSI based OC utilities like TRIXX on your 7970 to find out.

Maximums - Asus Z97-K /w i5 4690 Bclk @106.9Mhz * x39 = 4.17Ghz, 8GB of 2600Mhz DDR3,.. Gigabyte GTX970 G1-Gaming @ 1550Mhz

I thought 1.3v was maxx for 7970. I mean nothing higher was ever an option.

You need to use Sapphire TriXX.
