Has anyone overclocked the EVGA gtx 260 SSC 55nm yet? I was wondering what I can look to acheive.

GTX 260 Overclocks and Vantage Results
- Thread starter 555BUK
- Start date
Probably the same as my superclocked or maybe slightly better if you are lucky.
Nice one fella, worked a treat!
GPU-Z doesn't detect the 2D frequencies but Rivatuner does and the card is running about 6-10c cooler at idle You sir, are a lovely man Anyone else wanting to try this, I found a great utility that will format a USB stick and make it bootable, so all you have to do is add NVFlash and the .ROM file.

The HP USB Flash tools used to be good, but I couldn't get 'em to install under Vista 64.

Only done a few runs but seams crash with display driver error once I go over 705 on core.
xfx 260@705/1478/2320
Be intresting to see what people are getting with there 4870 and 4890's

Not that much less tbh as I went from an 4870 512mb card. My gpu vantage score is up but not by masses. I'll post my old results tonight.
However, all my framerates in games are way up and that's what counts

For people with Gainward GTX260 216 Golden Sample cards with part numbers EAN 4260xxxxx0025 only
This fixed bios solves issues with 2D clocks and voltages running at 3D settings. It should save you electricity and extend the life of your card.
You need these files.
0025 BIOS
NVFlash
Instructions.
1). Read the sticker on your card to confirm part number. It must begin 4260 and end 0025.
2). Make a DOS bootable floppy or USB disc (use Google if you do not know how).
3). Copy above bios and unziped NVFlash onto disk.
4). Change PC bios (if necessary) to boot from floppy.
5). Boot from Floppy
6). Backup original bios with command "NVFLASH -B BACKUP.ROM"
7). Flash new bios with command "NVFLASH -5 -6 0025260.ROM"
8). Hit "y" key when prompted and hold your breath.
9). Restart your PC and check 2D clocks work correctly.
If you brick your card it is your fault for following instructions an unknown person posted on the web. However, this is the official FIXED Gainward bios which I sourced directly from the Gainward Tech Support chaps in Germany. It worked for me.
This will not work on any other card because Gainward (it's actually made by Palit for Gainward) use non-reference parts.
This info is not available anywhere else (yet), so all credit goes to me
I flashed the bios and riva tuner and NiBitor shows the different profiles for 2D but the card still working a full speeds as I write now
Just checked my back up bios and it was the same version 62.00.49.00.03 which is also the same one at fudzilla's review.

Hey guys, im thinking of trying out overclocking my GTX 260 for more extra speed but before I do, can anyone please give me pointers on the best method of finding the cards max core, shader and mem speeds??? Is it just a case of me starting off with say the core speed, upping it until i get artifacts or crashes, then when i've reached my max, back down a little the overclock, then move to the next one i want to overclock???

I am testing a 260 216 right now and above 1152 i start to see yellow dots.
Core is ok at 729 and shaders at 1512.
If i push the core or shaders higher furmark stability test fails after a short period.
With the shaders set at 1566 or the core over 741 Furmarks bombs out in a big way.
I have 2 cards and will test the second shortly.
Edit: Memory on second card cant reach 1200 either, goes very slightly more about 1180.
I've settled on 720 1512 1152, wth the cards SLI'd.

You need to have at a minimum
EVGA precision
AtiTool
Furmark
AtiTool is useful because it scans for artifacts.
It does have other functionalitty but is basically broken and any tweaking of clocks is best done with EVGA precision.
Trying to overclock with it is hopeless if you have 8 series or higher cards.
Just use it for the artifact scanning.
Load up AtiTool and EVGA precision. set AtiTool running an artifact scan.
With ATI precision adjust the memory clock until you start to see yellow dots on the artifact scan.
Look carefully because the dots will start to appear before AtiTool recognises any problems so you will still see no errors on it's status.
You will notice that the memory clock goes up in steps, so moving the slider up a notch and hitting apply wont always adjust the clock you need to take it a little higher before the next speed step is applied.
You do the same for the shader and core clocks.
As to which to do first, i generally find the limit on the core before the shaders.
Note:
You will find that if you have them unlocked then a low shader clock will prevent you setting a high core clock so up the shaders a bit to allow a higher core clock.
If you keep them locked that wont be an issue.
When you are happy tweaking the clocks and Atitols artifact scan is yellow dot free it's time to test with furmark.
Do not be surprised if a minute or 2 into the stability test you have issues as it gives the card a good thrashing.
If furmark fails then it's down the shader or core clock time.
Everyone probably does it a bit differently but hopefully you have enough to get you started and you will develop your own testing process.
The real clocks are shown on the graphs.

Not bad results and every card differs. I am disappointed with my memory overclock as I see quite a few people acheive 1200+ and some 1300.
However somebody has pointed out that some manufacturers use faster memory chips which won;t overclock as high but their bandwidth will be as good or better so perhaps I shouldn't sweat on it.
Temps seem to be the downfall of my card's core and shader clocks. It needs 100% fan on furmark to keep it stable and 55% fan on ATItool to keep the yellow dots away at the speeds in my sig.
Once it hits a certain temp (can't remember as I am at work) that's when the benchmarks start to fail. Not too bothered as it's going under water later this week.
So for quietness (rest of system is watercooled) day to day benching I run at 729/1542 from memory and leave the fan on stock 40%.
Also if you leave your core/shaders linked I find that the shaders fail first. Once you reached the highest stable overclock with them linked you can normally then go higher on the core unlinked.

core is prolly fine, unlink the core/shader clock and back the shader clock down below 1500 (think 1458 is the next increment below 1500) and it should be fine upto 729 core.

What temp should I be looking for in games with my evga gtx 260 ssc core 216?
I seem to max at at 70c at 690mhz core clock. Is this okay? Could I have the core clock higher?

Depends on what your fan is running at? Have you left it at 40%?
70C is fine btw and from memory the fan profile won't have even upped it's speed by then (or maybe just up one step)
My card maxes out at 70C but for the silly maximum clock speeds it really doesn't like anything more than 64C before it artifacts etc so I need to ramp up the fan speeds to keep it cool enough and artifact free.
at 729/1542 I can just leave it on the stock profile.

70c at 47% fan. What temp is good to run at? like would 75c be acceptable?
75c is fine as well so long as your card overclock is stable. As I have said my card does not like to be above 64C with the extreme overclock but happy at a lower overclock at 70C.
