post #961 of 1562
hi steven thanks for the advice. is there any way i can test them individually without pulling them out of my case?

EDIT: i just ran it 5 loops with my full attention. no green spots anymore. Weird! scared the s*** out of me. didnt wanna RMA!

you can open up nvidia control panel and turn off SLI....however this only stresses the top card, and in order to test the bottom card, you will have to move it to the top PCI-E slot

let us know if you have any further questions....RMAing the cards do suck...but you do have EVGA to back you up....they ship a replacement card to you first, then you ship the defective one back....incredible service smile.gif

noticed that my cards dont use over 110% tdp on max read so i turned it down to 120%. was wondering if i could mess with the voltages. i dont like it going 1.175 all the time. anybody tried messing with it yet?

by the way thanks for the info again steven. i see u have the ftws in sli too. mind if i know what u got?

If you don't want the voltage to stay at 1.175v under load don't mess with the power target. But why wouldn't you want it to hold at that voltage under load? It will still drop down when the clocks drop.

i haven't tried overclocking it yet....because even at stock, its already running hot as heck...the blower design isn't the most effective way of cooling....and not only that, my room is hot in the summer

but out of box clocks are 1215 and 1163

I've always wondered... for the Asus users with Maximus/ Rampage boards that have on board tweaking such as through OC Key, does it work to boost voltage from there, circumventing the locks placed on by the board makers? Or is there some sort of a hardware lockdown that prevents Voltage increase.

Like the MSI PE 670 for example, if you used a Maximus level motherboard with onboard voltage tweaking, couldn't you increase the voltage past the 1.2v limit?

I have always thought that feature as just overvolting the bus. The cards voltage regulators would still limit the card. BBBBUT if Im wrong anyone please correct me thumb.gif

GOD... I feel so awesome now. Last week I received my 670’s FTW Backplate’s ( aka 680 ) and I had to take my RiG down for Backplate installation and some new MoD ( two 830’s 128GB and two Vertex 80G, after the new SSD’s mounted on the side of 5.25” cage I decide just to run some bench to how it goes with Backplate and PowW.w..n.n.n.n.N....M.....W...w.... first run I broke 15k.

My GPU is an MSI N670 GTX Power Edition
I ran some benchmarks in Crysis 1 last night to determine how my OC's scale with regard to gaming performance.
All test were performed with my CPU at 4.4 GHz using a my custom Crysis config @ 1920x1200 with 8x AA
The FPS figures below represent the average FPS over 5 loops.

Stock: Core 1215 MHz | Memory 3005 MHz = 56.575 FPS
OC1: Core 1266 MHz | Memory 3305 MHz = 60.830 FPS
OC2: Core 1280 MHz | Memory 3500 MHz = 62.165 FPS
OC3: Core 1300 MHz | Memory 3602 MHz = 64.005 FPS
OC4: Core 1316 MHz | Memory 3703 MHz = 65.115 FPS

My highest stable OC yields 8.54 FPS over the GPU's factory default overclock. (15.10% increase)
The OC i run 24/7 yields 5.59 FPS over the GPU's factory default overclock. (9.88 % increase)


Question: If i underclock the core and memory in Afterburner down to reference 670 settings and run the same Crysis benchmark... will the numbers i get accurately reflect the performance of a reference 670?
