R9 290 or GTX780 ??

[jj109]

Glad you could join us, can't wait for you to add to our results!

That said...

Really should have gone for more vram /\

Dammit balla, I was wondering why my 780's score was only 3080 until I saw there you were a full 100 MHz ahead.

 

[BallaTheFeared]

Went to low on the vram, barely scaled over 1330.

What's the difference between voiding the warranty through improper use (i.e. hilariously high voltages for TSMC 22nm) and voiding the warranty through improper use (i.e. custom vBIOS)?

I don't think I could have been much clearer. EVGA has stated (on the Classified) that the use of an unofficial BIOS in place of the LN2 BIOS would not void the warranty. Now if there was evidence of an obscene amount of voltage being pushed through the card and that caused it to fail, who is to say what they would do. But a custom BIOS in and of itself would not void the warranty.

EVGA has also stated that cards must be RMA'd in factory condition including vBIOS wink wink. I take that to mean as long as we get the original vBIOS back on before we RMA, it's all peachy.

So why do some people differentiate between abusing an unlocked voltage and flashing a vBIOS?

If the card dies with a warranty voiding BIOS you will not be able to RMA it.

Balla: Is your 780 the EVGA GTX780 Classified?

Nope, its more like a ftw with a bigger cooler.

Look at a powertune+power limit problem on overclocking a custom 290x card(that still have the reference PCB): http://www.pcper.com/reviews/Graphi...B-Graphics-Card-Review/Overclocking-and-Concl

Quickly read the single page you pointed to.

What problem...??

The reviewer had no complaints..

The card is throttling even though it has enough cooling so power tune is keeping it from sustaining boost.

 

[BallaTheFeared]

I wonder if Ryan was aware you could scroll the bar to enable +50% powertune with Trixx?

 

[rtsurfer]

Well the reviewer didnt post the OCed temps so it is hard to know if it was throttling even though it had more temp headroom.

And it still averaged at 1214 from a set speed of 1225, which is not bad.

Maybe this is a stock Bios/PCB issue which can be overcome with the custom PCB version or modified BIOS.

I am not too worried about it as this happened at 1225 Mhz.
Considering what the few owners of the 290X have posted, 1200 is around the max OC possible on reference PCB. Some fluctuation above 1200 Mhz doesnt bother me as the card might be at its limit.

 

[Gloomy]

lmao what a boob, he can't even test for stability properly without raising the limit

 

[Leadbox]

That looks like powertune working as it should, throttling the card to keep power consumption in check

That's why i said some posts ago that i suspect a limitation in the 290(s) PCB... I presume this is keeping the R9 290 cards to reach good overclocking levels.

PS: Adding information: could a redesign to a 8+8 PowerPins PCB could bring better overlock results to the card?

 

[BallaTheFeared]

Silicon prevents cards from reaching good clocks.

It's not like you can throw down 600w into the card with 1.5v for daily.

If the cards are hitting a limit at 350+w consumption from powertune how much higher do you honestly except them to go if allowed to use 550? Another 15-25 MHz? The power scaling is going to become obscene for the performance gains at those consumption/voltage levels.

 

[rtsurfer]

Actually

From the OCN's GK110 vs. HAWAII Bench off thread.

1300 Mhz and beats Balla's score too.

Source: http://www.overclock.net/t/1436635/...s-team-red-gk110-vs-hawaii/1540#post_21477173

I did not want to use some random user's benchmark scores, but sadly I cant get my hands on the Sapphire 290 as Newegg is price gouging and OOS.

Edit: Forget the last part.
Found the thread. Silly me.

 

[BallaTheFeared]

Isn't it a bit early for desperation? Yeah pity all the 1300/1800 water cooled R290s are OOS on newegg right now, I'd love to pick one up myself.

What's next, I post the 95.4 FPS 780 score, what are you going to do then?

 

[rtsurfer]

What..??
I wondered around OCN because our sample size for 290s is really small.

I did point my concerns in my post on the reliability of the results.

I meant that I wanted to buy the air cooled sapphire 290. Also I cant afford to pay to 559$ for it anyways.

 

[guskline]

If I'm going to spend $559, I might as well save up another $20 and get the EVGA GTX780 Classified for $579!

Here is the card I've been using:

http://www.newegg.com/Product/Produc...82E16814125488

$510 right now.

It's not a classified. It's no where near as binned.

That doesn't mean you won't get lucky, but the chances you'll get something like I got are far higher (got it twice in a row basically) than getting a 1300+ 1.2v classified which isn't common everyday but it's not exactly rare either.


If you want max clocks go with the classified or lightning or HoF, you'll have buyers remorse otherwise because those cards are cherry, they're binned that way.

Here is the HoF for $520:

http://www.amazon.com/Galaxy-GeForce.../dp/B00DZIFN4M

With softmods you can take the voltage to 1.4 and beyond, you don't need a classified for voltage. You will need to flash for higher power limits, but the HOF is like +126 out of the box, mine is 113. You should be able to run 1.3v off the stock bios with a HoF, whatever that gets you for core/vram speeds is purely chance but it is binned.

 

[l2ez4m]

Prolly most comprehensive up to date OC 290X vs OC 780 review from Lepilov@xbitlabs puts 290X@1130Mhz - 2% faster @1080p and 4% - 1440p against overclocked 780@1032/1085/1162Mhz (core/boost/max actual). Maxing out Oc potential reserves likely gonna tip the performance scales marginally towards the greenside.

 

[blackened23]

The heck? I don't see that review on xbit labs anywhere. Link please. That image you provided is from some website in Russia. I don't see the applicable review on Xbitlabs. Anywhere.

 

[l2ez4m]

Oh yeh, there is about two weeks incubation period from their russian review and english version.

But the question i'm pointing lies in this. How much those numbers can be improved with a decent PCB+Great Cooling?
There's something making this numbers be too high like this.
Maybe a revision on Hawaii chip can too help to make its power consumption/ overclocking levels be better.
