Can you look at the picture and tell me which temp is vrm and which one is ram?

1 core

2 core

3 mem

What about vrm as voltage regulator module? Where can i see the temps? What are ram safe temps? And how much voltage is safe for vrm without heatsinks.

Only core cooled by stock. I have four 120mm fans blowing over the card tho.

What? Are you trying to fry your card on purpose?? Best way of reading vrm temps in a meaningful way is thru gpuz sensors.

No i don't want to fry anything that is why i'm asking. My card came without a single heatsink!

Like this one:

That is why i am worried.

I can only see core temp in gpuz(?).

Holy carp, I've seen soem cheap stuff but that's really pathetic on an upper end card. It's a $400 card for crying out loud Sapphire. That said isn't there at least a shroud over the whole thing?


Ok, I would buy a heatsink kit for your card.

This is how it looks originaly, the temps were up to 80 with a minor OC. Now i bought accelero s1 plus+2120mm fans. The temps are max 60 with 1150 on core on full load. Dont get me started on noise.

I'm only worried about vrms and ram. More the vrms tho since ram temps i can see and they are in ~60C.

Would like to get my hands on the front plate that coveres ram and vrms from OC version of the card but i don't think that is happening.

If you have any ram heatsinks around they will work for the mosfets, I just pulled out the hacksaw & cut some in half to fit.

This sound EXACTLY like my card. Although I can usually get a away with slightly less voltage for those clocks. Any higher core than that and things start to become shaky. I have managed 1225 on the core for a 3DMark11 run, but gaming and Heaven don't like it that high, and Vantage cuts out too through the spaceship scene.

I would say that anyone looking to really push these cards, really needs to get the volts up a little. As long as you have an after market cooking solution (Sapphire Dual Fan, Gigabyte W/Force, etc.) you should not worry about temps until you're high in the 1100's or hitting 1200Mhz if the GPU can take it. Water cooling is another story entirely, but the massive size and quantity of heat pipes on the custom coolers coupled with the appropriate fan set up, which most have, have enabled these cards to operate at speeds WAY past what was intended.

I still say AMD released these cards well under clocked. Almost ANY board will hit 1000Mhz without breaking a sweat on stock fan profiles and near stock voltage. Yes, we wouldn't be raving about how we get and extra 400Mhz out of the core on most of our cards, but in turn, the benches would have been that much more impressive in the reviews.

I hate hearing how the 7950 is a NO GO now with the 670 out, even though my card is beating a slightly OC'd 680.

But I'm sure the vets here have said and heard this a million times, so.... smile.gif

That is the same card that I had to RMA the first time before I bought the OC version. Being relatively new getting back into the PC scene after 6 or 7 years, I now know a few things that I would do a little differently. Possibly number one would be not to buy reference cards unless you do not want to overclock, or are putting them under water. I LOVE getting the most out of my card, and when that happens, the standard shroud and much to be desired heatsink do not do enough to protect your gear, really.

The beefy cooler solutions that go onto the OC versions of the cards are so much more comforting. The amount of copper on my card is awesome. People say "why get the OC version, you can OC it yourself?" The thing is, I pay for the cooler, not the extra Mhz that comes along with it. That's the main thing you get an OC card for. Most have immaculate coolers which are also tonnes quieter.

Hello guys, i am from brazil and i wil ltry to explciate what is happening with my card... Sorry for the bad english, i will try my best,ok??

Thats deal, i have 2 7970 from XFX Core edition, but one of those started to show some coloured points in the screen, some times the monitor dislpay gets black and come back, like i shut him down, but is the vga, but this happens just when i am at the windows, or surfing on the internet, not in games like bf3 or mw3 and not in benchmarks like 3d11, 3d vantage and heaven benchmark... Both are under water and i dont think i can killed the vga with the overclock, don't know exactly what happened, but i would like your opnion because you have lot more of experience... Soem friend of mine told me that can be like a thermal pad that was not corrected put on the block and vga is in contact with the block, something like that... If you need some pictures i can take some ones to you guys.. But i turned off the vga, i am waiting some stuff that i bought at ppcs to finish my worklog, so i will put the vga back to stock cooler, test to see what happens and try to block again..

Thank you everyone for anything you can do for help me...
