I wonder if the warm temperatures are occurring with the 326.41 or later drivers? Supposedly there was a fix for the custom VRM in the 326.41 and newer drivers.

I think only a few cards in Europe are showing up with Samsung modules since their shipment took so long. I actually like my Elpida memory! biggrin.gif

Hey guys,

Where can I get my hands on a modified bios 3A revision of cards?

  • 1450 - 1500 core starts giving a lot of artifacts. I wasn't able to pass 3DMark11 at any voltages (including 1.5v when it starts throttling) without a driver crash. This is with default memory clock and voltage. It's just not gonna happen.
  • 1.4875 was the highest I could get without throttling. Even then my temps were approaching 60c - which is just ridiculously hot on water.
  • 1400core seems to be the "sweet spot" in regards to power. I'm able to sit pretty at 1400 with 1.35 classy controller or EVBOT and still OC my memory up to 7500-7700.

As I don't have a multimeter I'm not able to verify exact voltages. I was only using EVBot. However in my opinion, I just don't see the advantage of going above 1400 for every day gaming. I might play around with 1425 but I'm not sure it's really worth having to sacrifice memory overclock & water temp.


Anyone else on water with similar conclusions?

I can hit 1411 on air and 1.3volts so when i get it on water im sure i cane get to 1500 with less than 1.5 volts

You can for sure. Problem is you run into artifacts/instability going past 1450 (even 1430s are iffy). I could not pass 3dmark at any voltage going above 1450. I highly doubt it's possible to have something stable longterm over 1450 on a standard loop.

However, results may vary so I'll be interested to see once more people get blocks on.

Also I just finished benching a really high Valley run. Who say's Elpida memory sucks? smile.gif



1450 core / 3947 mem (7894)

Just finished installing my Classy and so far so good! Just running the stock bios and have passed 3dmark 11 and other benchmarks at 1293mhz core @ stock 1.162v.

Nice! That was as high as I could go on stock as well. Did pass 1302 with 175 on the mem, but it had artifacts at the end of first and second part.

I did a search but didn't see anything about this. EVGA card owners, we have a double bios built into our cards. Sweet, can load a custom bios and keep the stock in the first spot.

Yep. There is a switch on the card that allows you to choose LN2 bios or standard bios. thumb.gif
