How and what to overclock GTX 580M to?

Hey everyone. So I ordered some thermal paste online waiting for it to come in. When I search for "overclock GTX 580 or 580m" nothing comes up so I am making this thread. I want to get a little extra performance out of my GPU. Was wondering what you have to change to overclock and how much of an overclock to do that is safe and not risking my GPU of being fried. Please post your input on this question and I would definitely like to here from Widezu on this one of course Thanks guys

 

You could try using one of these programs.

msi afterburner
nvidia inspector

Don't raise the clocks by like 500 though. You can experiment by raising the clocks little by little, then running a benchmark program like 3dmark06 to see if it's stable.

 

Overclocking is not an exact science, but I assume that you've installed the power throttle fix?

why dont you start with a 10% OC (e.g., 682/1364/1650), run furmark, check your temps. If its all good, then try 15% (e.g., 713/1426/1725) etc, then if its good, try 20%

Each card is different, so there is going to be a lot of trial and error. The trick with the 580m in Alienware is you want to OC as high as possible, but avoid the 77c temp throttle

 

A question you must answer for your self young grasshooper.

Each card is differant and has differant limits.

 

You've been watching way too much Kung Fu

 

It seems like it.

 

Okay now obviously nvidia inspector is the best thing to use overclocking. When you click the overclock tab its brings up with overclock settings. What exactly am I overclocking because there is the tab with P1 and P0 and etc. if I can remember corretly what thats called. Basically dumb it down a bit because I never overclocked a video card.

 

Start by overclocking the P0 settings. Those are the basic 3d (gaming) clocks. If you're using the stock 580M vbios, then you're limited to .87v, which allows most cards to support up to 750/1700(850)/1500. Some will go on up to 800/1800(900)/1600, but few will go higher without flashing a new vbios to increase P0 voltage to .92v. The P1 settings are the clocks that the card drops down to when throttling occurs, intended to mask or reduce the effects of throttling. These can be separately increased all the way up to the revised P0 state settings.

 

Okay and do you suggest to overvolt to 0.92v just for gaming? And when you change the clocks for P0 and P1 do they usually stay tue same? Also, what is the highest overclock that is still considered pretty safe for the card? Thanks Rev

 

Nope, there is no need to increase P0 voltage for gaming. If you find the need of a bit more power, try overclocking to 700/1600(800)/1400. Increasing voltage to .92v is really for benchmarking. You'll find that the 580M can handle most gaming environments using stock settings. Just use it and experiment a little. With the built-in throttling triggers and shutdown points, you are well (overly) protected from pushing the card into dangerous territory.

 

I'm trying to do the same thing with my GPU. I tried 682/1364/1650 then I run 3DMark11 then got a score of 3802 using stock voltage.

Then I tried 713/1426/1725 then run the same benchmark then I got 2923

I thought the score is gonna go higher the more you OC the card. Is there something wrong with what I'm doing? Thanks.

Edit: My max temp for both test is 65C.

Also when I tried to rerun the 2nd test, after moving the slider, its going back to stock clocks when I press apply.

Edit2:
Well, I reboot the laptop and did another run on 3DM11 @ 744/1488/1800 and I got 3995. I guess the reboot resolved it.

 

What are you using to overclock?

 

Nvidia Inspector.

 

Glad you have it working. I was having a hard time coming up with a theory that made any sense. Without suggesting that anything is wrong, your score (P3995) is a little light for 750/1800(900)/1500. I got P4254 at the same settings. Probably just a matter of background programs or drivers or the like, but be aware there is probably more to be had without even further raising the clocks.

 

Yeah, I was hoping I'll reach 4k. Maybe its the CPU difference? I think I have Tera running in background when I did the last test. I should have closed it. I'll try tinkering with it again when I get home later.
I didn't know that this feels quite addicting lol! I feel like I can still go on higher.
Do you advise rebooting everytime you do another test? I'm thinking just to refresh the machine.

 

You don't need to reboot after each test, but closing background programs is important. Any non-critical program, utility or service that is using CPU cycles is potentially at least reducing the performance capabilities available to the running benchmark. Don't need to get crazy about it, but streamlining the operating environment pays dividends. It can get very addictive, but it's also lots of fun and a great way to learn about your systems strengths and weaknesses.

 

It's weird. I got 3995 @744/1488/1800. Then I tried 750/1500/1800 and I got lower @ 2797

Is there something wrong with what I am doing? Or with the card?

 

It could be that there is a delay before the 580M kicks in. Go to Nvidia Control Panel, select Manage 3D settings, click on the Program Settings tab, click on 3dMark11 and tell it to use the 580M for that program. Optimus can be a PITA, which is why I ultimately disabled the IGP and currently use the 580M exclusively since my R3 is plugged in nearly all of the time. Could be something else, but this is a good place to start.

 

I've run into this problem before. For some reason, after an initial reboot, the tests will run best. No matter what I did, I would always not score as high as my first run, even if the clocks were higher. After doing a restart, and rerunning with the higher clocks, I would get a score that would reflect the clocks.

When I was benching with any 3DMark programs, I would have to do a restart to get the best scores.

 

I think that's exactly what is happening. When I got home, I did the following:

- Turned on my R3.
- Run 3DM11 @745/1480/1800 and got P4051. Finally happy I reach 4k
- Decided I want to try 3DM Vantage and run on the same clocks and got P12163. Lower than my stock setting results of P14820.
- I did a reboot and tried again with same settings and I got P16135.

I think I'll just reboot before every test to be safe. BTW, what are the dangers in OC'ing using unlocked voltage?

 

How do you exactly stop the throtling?
My 580M gets throtled at more than 702MHz core...
can anyone help me here?
I have a DELL 580M from a X18 in a 16f2 MSI...
Thanks!

 

What temps are you throttling at? Have you tried this? http://forum.notebookreview.com/ali...e-fixing-m17x-r3-580m-thermal-throttling.html

 

Just want to bump this too. I would appreciate it if someone can point me to any procedure on how to unlock my GPU voltage and some guidelines on OC'ng outside the default voltage will be nice too Thanks.

 

The only way to increase voltage for your 580M is to flash a modified vbios with the 3d clocks set to .92v (vs stock @ .87v). That's currently the only choice available. You can get the modified vbios here: http://forum.notebookreview.com/ali...x-no-need-modify-system-bios.html#post7976588 (bottom of post, download file vbios.zip and use the file 580m92v.rom). The modified vbios also includes modifying the P1 state clocks to be equal to the P0 clocks to mask the effects of the power throttle (mid-60C's). Widezu includes flashing instructions in that post, together with links needed to create a bootable DOS stick and the NVFlash utility. This will allow higher o/c. Cards vary, but most will go on up to 865-875 core with the .92v vbios, but best results have been obtained limiting the core to ~850 and memory to 950/1900 max. Be careful with heat; it is prudent to keep the fans running full speed when pressing the upper limits at the higher voltage under load. It is best to avoid Furmark altogether when running the higher voltage.

 

I've been running the .92v vbios for a little while now and have been pleased that my card hasn't fried yet, lol. I just picked up FFXIV and have noticed that with an OC and the .92v vbios, I am hitting some really high temps. The highest I've seen is 78C, but I didn't get any throttling. I think I am going to go back to the .87v vbios and see what my temps are with it. Hopefully I'll be able to keep my system cool enough to enjoy the game and not fry my card. If it does get fried, hopefully I'll get a nice replacement. A 7970 or 680m (when released) . Hopefully they'd be out of the 580m and 675m if I do indeed fry my card.

I do play with the back elevated (I use a 100 pack of index cards to prop it up) and if I'm playing in bed, I use my cheapo notebook cooler.
