GTX 580m OC

First of Happy Thanksgiving to everyone! Hope everyone will have alot of good food!


I had one small question regarding OC'ing this chip. Iv been playing around with it lately at the stock vrefs and have been able to achieve 755/1510 as the OC If I go much further then that it becomes unstable.

I was curious what others have gotten with the stock voltages. Have you been able to push it higher?

Thanks in advanced!

 

That's a decent overclock on stock voltages. Most users are able to get much higher memory clocks though. I've seen 740/1800. Don't skimp out on the memory but I wouldn't advise going higher than 2000.

 

Ya know I haven't even pushed the memory Ill have to try doing that my value up there was the core/shader. I just assumed this is what people are posting. Ill have to play with the memory and see what I can get.

So just did a few rounds of BF3 and its stable at 755/1950 core/memory respectively. I'm pretty pleased atm. I also just threw on your vbios from your link. +rep for that!

 

Nice remember you have to OC both P0 and P1 to avoid throttling.

 

Hi,

With the 0.92v, I manage to push mine up to 880, stable enought for benchmark. I've didn't start playing with memory, what will it change for bench/games (vs higher clock for core/shaders).

(Widezu69 modded bios works perfectly, thanks )

 

Higher memory bandwidth gives faster loading textures and objects. You have a nice core OC there but you probably have to dial that down to around 840 if you want to bench using a memory OC of over 1800.

 

What's the Nvidia counterpart to Sapphire TRIXX for overclocking the 580?

 

Best to go with is Nvidia Inspector for many reasons. First of all it is user friendly, looks a bit like GPU-z. Secondly, if you flash my modded vbios for throttle removal, you must use Inspector to OC both profiles (check the link in sig for more info) and thirdly but most importantly is that it has an UNLOCK MAX button which allows the sliders to go much further, for benchers

 

Widezu if you use your vbios do you still need the one from Dell Drivers?

 

No the vbioses in my fix are the same as the Dell update with a small modification to remove throttling. You also have a choice between the 0.87v and the 0.92v one.

 

No.

Yeah I have been using Nvidia Inspector and I ended up at 757/1950 and did this on P0 and P1 stock voltage with widezu's bios. I didn't push the memory much higher since widezu recommended not going past 2000.

I will likely be putting the higher vref bios on at a later date and give that a spin to see how much more I can open her up.

Also I still have to find a good thermal paste to re paste with. Been looking at Arctic Cooling MX-4 or IC Diamond 24. Anyone have any thoughts on thermal pads?

 

I have Fujipoly pads intended as replacement pads, but still using the stock pads, which are working well.

 

PLEASE DO NOT USE IC Diamond. I know I have recommended it in the past but when you go to repaste and your removing the old IC Diamond you scratch up the die and the heatsink because of the diamond particles in it.That's how I bricked my 6990. There are no abrasives in MX4

 

^^ THIS. I've been telling anyone who listens to NOT use ICD-7. AC MX-4 or Prolimatech PK-1 FTW

 

Interesting I had no clue. So why is it still so highly recommended and is there a safe way of applying it?

 

Prolimatech PK-1 -> Pure damn awesome! And the tube is way bigger

 

When I get my 580 I'm going to do a clean install.Before I do that should I do what Widezu said with the flash drive. Also do I install first the Dell 580 drivers and then update from Nvidias website?

 

It's not the application, it's removing it if and when you repaste

 

Its all hype bro. Someone recommends ICD to you, you use it, you then recommend it to someone else. Doesn't matter how you apply it, I'd stay away from it. But to be fair, ICD works ok on desktop CPU's because they have lids on them (a metal plate which protects the actual CPU die)...but all CPU's and GPU's in laptops are lidless

Actually, ICD is only an average paste once you factor in contact level

HEre is a list of most thermal pastes in 2011. look at moderate contact for what you might expect on a laptop

2011 Thermal Compound Roundup – Results Compilation | Skinnee Labs

you'll notice that IC Diamond is not on the list because Skinnee has to wait until all the testing done...then use ICD last because it alters his water blocks

his explanation:

"IC Diamond will only be tested after this testbed is ‘retired.’ Due to its severe polishing effect, ICD is not something I can test 15 mounts of and guarantee that the testbed will perform the same after as it did before (it permanently alters the CPU IHS and the block bases). That said, I did briefly test it while pre-testing for this testbed and procedure and I can say it’s really good with Poor Contact but does not improve much as contact improves, making it just an ‘okay’ paste when you have at least moderate contact, which most CPU blocks, most GPU blocks, and most heatsinks do"

 

BTW Dell is sending me a new 6990 and heatsink. No charge

 

How did you pull that off?

 

pls use this to clean ur proc/gpu core /heatsink

 

Well first of all I didn't tell them I repasted the GPU. Also I wanted to ask, if I'm running on Intel Graphics would that give me poor CPU performance?

 

if you wan request a new heatsink... just told dell, ur gpu is getting overheat.

 

I used IC Diamond 24 and my cpu and gpu die both seem to have scratches .. What should I do now?

 

there's nothing that you can do. Just don't use it anymore

 

I'm glad this thread is turning out to be informative for others. Its been an eye opener for me. I'm not really new to OC'ing a computer or video card (I haven't done it in awhile) but I had never done it to laptops because I never really owned a powerhouse laptop.

I will probably endup going with Arctic Cooling MX-4 when I re paste my parts.

Just goes to show there is always something new to learn =) Thanks a bunch for all the info.

 

Prolimatech PK-1 is probably better. It performs just as well as IC-Diamond from what I have seen and doesn't have the scratching problems.

 

i'm a big supporter of PK-1...this stuff is liquid gold

 

Haven't tried it yet. Must get some.

 

widezu, what are your clocks?? what do you recommend for a mild OC?

 

For BF3 I use 800/1800. But I'm on the 0.92v vbios.

 

I ended up ordering some Prolimatech PK-1 since it seems to be the crowd favorite here. Thanks again for the info.

One last question what thickness pads are you guys using that have replaced them?

 

Thanks Widezu69, will try to push higher for memory, and try to beat my 18K on vantage. I personally use MX2, that works very well. the 580M GTX works like a charm and never hits higher temp than 66°C.
Nobody use old artic silver ??? Alwys use it on my cpus and always had good results (with a good cooler like the U3 from coolermaster).

 

hey widezu... you say you use 800/1800 for bf3 now for me i'm not into benchmarking just looking for good performance in gaming. Should I use 0.87 or 0.92?

 

I don't know if Wide will see this thread, but I wanted to let you know that he has kinda changed his mind on OCing that hard. His card died and he had to replace it, he advised me a few days ago that going that high really was not smart or needed.

Another forum member suggested that the memory may not really need to be OCed, since in a real-world situation you wont gain much if anything from the memory OC. Wide also said the memory is not cooled nearly as well as the rest, and he thinks it was the memory that died in his last card.

If you want to go over 750 core you need the .92 vBios.
