evga 460 ssc+ gtx + crysis demo results + OCs?

[mikedev10]

hey all. i am wondering if anyone else has this card and what comfortable overclocks they have done? did it take more voltage to achieve them at stable speeds? should the core and shader clocks be adjusted independently?

here are my results, trying to replicate with the framebuffer warhead bench tool. is original crysis much better in 64-bit vs. 32-bit resolution? or is the game really just dependent on gpu? will dx11 yield better results or just more visual gizmos?

also i was getting these weird lines on the floor, but only in the beginning portion of the demo. is this normal?

That's normal, the AA is just messed up on that level.

My GTX 460 is at 950 core and 1100 memory, but it's overvolted to an extent.

how hot? how many volts? what do you get on this demo? is the shader adjusted up with the core? what are you using to tweak these things and which card do you have?

this version of the software was from evga. i did not install their oc program "precision" on the disk that my card came with, although i heard it was made special for this card so maybe i should. the version i installed is right from their site. it doesn't seem like i can save profiles into slots or change voltages. the core and shader clocks seem like they are always linked as well, although between the ssc and ftw versions of this card they have different cores but the same shader clockspeed.

It doesn't go past 64C or so. I hacked the bios to allow extra voltage. I have it set to 1.175v. I don't know what I score on that demo, but apparently a GTX 460 overclocked this high is faster than a stock GTX 470 in terms of performance. I used NiBiTor and NVflash to hack the bios, and I use MSI Afterburner to overclock the card. I leave the shaders locked to the frequency of the core. I have an MSI Cyclone 768mb card.

If your card has reference cooling, you might have trouble reaching higher speeds. Also, be careful when adjusting the voltage. I took a chance in running mine so high. I've heard of people frying their cards, so take it easy.

same voltage for cpu and mem? i changed mine through evga's "e-leet" tool. i was scared of going higher because i don't know where the "generally considered safe" range is. what's the highest that factory overclocks apply? i'm guessing they tie it with greater heat dissipation but i don't think i got over 60 or so.

i don't know what type of cooling my card has, it's the evga 460 ssc+ ; did you add additional cooling to yours? http://www.newegg.com/Product/Produc...460%201380

so here's what i find really confusing:

why is my card slower than a FTW?
ssc card oem: core/shader/mem 850/1700/3900
ftw: 850/1700/4000
oc: 910/1820/4010

mine is overclocked, but the one in this article on this machine is a regular evga ftw - http://www.anandtech.com/show/3987/...renewing-competition-in-the-midrange-market/7

yet it appears to be handily beating my fps average (mid 48)

how can that be? the specs of my card are non-trivially higher, as is *most* of my machine. why are they getting a 50?

i thought it was the cas timings, then noticed my ram was set at 9-9-9-24 but also at ddr3 1600. i went into the bios and changed it to ddr 1866. i had to bump the bclk down to 102 because the kb would no longer work. memory bandwidth went up in sisoft sandra a significant amount. fps went down, 48.23 avg 33.72 min.

does my memory bandwidth matter so little? is cas latency this significant? (7-7-7-20 in the test rig)

based on this i expected my frames to go up

i really am quite perplexed as to why
1. increased memory bandwidth (and a minor drop in cpu cycles - which doesn't run at 100 during crysis anyway) did not increase fps
2. my card/rig is slower than that of the tested FTW

 

[mikedev10]

would i be correct to attribute this difference to the i7 on the test rig having 8 mb L3 cache vs. my 6 mb?

 

[mikedev10]

ok, so i figure that can't be right based on this either.

halp? why is my score lower than what one might expect?

AFAIK I have only changed the GPU voltage, not the memory. In terms of safe voltages and what other cards use, I'm not sure. I'm pretty sure mine was able to go up to 1.05 or 1.1v by default; with my mod I think I can take it up to 1.2v. For me it's been stable at 1.15v, but I don't use the card all that heavily and there is a chance I could burn it up.

My card has the "cyclone" cooler on it, and it seems to work really well.

i have version 1.1.1687 of crysis warhead - is that not the latest?
