I freaking love ICD7

OK, after some apparently much-needed 'cure time' with ICD7 and using the auto-tune settings for ATI Overdrive, I've managed to get 865/1215 with my 5870, no glitching or artifacts, and it never breaks 87C in Furmark. (I didn't really want to use Furmark but I couldn't think of a better way to test my paste job besides auto-tune.)

Just thought I'd share.

 

Booya! And I hate you...

Wish I could push past (correction) *740*/1040

 

I E-N-V-Y Y-O-U ! ! ! !

 

and it's the Best Buy version too! (not that it should matter, but still.)

 

Wow, did you have to raise the voltage for those clocks? I'm just now working on stable OC for my 5870m, and am up to 780/1110.

 

nope, stock voltage. running chastity's modded vbios, to enable overdrive... and then I just let ATI Overdrive within CCC do its thing.

 

lol auto tune eh? I've never had good results on any system with that ... interesting. My 780/1110 clocks are maxing at 70c in furmark with stock paste (no, its not in my freezer lol)

 

did you mount it inside of a snowman? jeez man that's pretty good with stock paste.

 

Haha, nope ... testing room is at 73F as well. Trust me, I'm as in disbelief as you are!

Edit: Just happened to think ... what drivers are you using? I'm on custom 10.9a. I read that they're giving lower temps to people, though no idea why.

 

Great results. I have the Best Buy version too, and I haven't re-pasted yet. My memory won't clock past 1060 without some serious artifacts on the desktop screen. The core hits 800 with ease. When I get enough nerve, I'll re-paste and then make sure the memory heat pads/tape is in place. I have a theory they are not, but on the other hand all cards are not equal, and I just may have a dud for overclocking.

 

ICD7 has nothing to do with your stability at higher clocks, your chip can either handle those clock speeds or it can't. You're not increasing your voltages so you're really not pushing the "thermal envelope" where extreme cooling comes in to play. You can thank Asus/ATI for giving you a good chip.

 

Nice results. I just ran auto tune and Ive yet to repaste and received results of 865/1110. Obviously ICD7 repaste has helped your system.

Would love to repaste but until I really have to Ill just leave it. Not game enough yet lol.

 

Well, Evergreen, in general (well... just in my experience with the desktop Juniper and Cypress chips) is rather tempurature sensitive during OC. So lower temps *might* help. I say might, because you are correct, the bigger factor is going to be the individual chips, and the luck of the binning process (determining whether that chip is worthy or not). While temps mostly matter in extreme OC, lower temps will never hurt - especially not in a laptop

 

I cant install Install AMD overdrive! Did you managed to install it on your G73Jh or what machine?

THX

 

It says AMD Overdrive failed to start!!!

How can I run it?

 

Can you post a pic of your screen?

 

Mine screenshot?

 

you are wrong, the clock is set so it is heats reasonably, the clock can be increased "indefinitely " If you can maintain your thermal limits, many people forgot to take Moores Law completely into account, people always remember the transistor doubling but forgot the thermal overhead, that's why we don't have 20 Ghz processors like the curve was supposed to, and how else do you think people can double their frequencies or even triple them? Liquid Nitrogen, people set records that way.

 

nice number you get there, mine max out at 800/1100. above this, i will get system freeze

 

850/1150 here 1200 memory timings gives me some lovely GSODs

 

how lovely? take pics please!

 

1150 on the memory started turning up artifacts in FurMark, so I dialed it down to 1100.

Room ambient: 20.2C

(I love having my new fan controller on my desktop, and having temp sensors)

 

I can furmark for hours at 850/1100, but in actual games it doesn't take long for the driver to crash (after which it recovers). First time I've ever ran into this sort of issue while overclocking a card.

 

I use 800/1300 clocks for gaming now for months without problems

 

Can someone tell me how to start amd overdrive and give me the download link vecause from ati site there is only download for desktop. Where can I get mobile download?

THX

 

Overdrive is part of CCC. You need to use a vBIOS with it enabled to see the tab in CCC.

 

lol, people that dont even know how to search i nthe web should quit trying to overclock an vga card xD, btw icd7 is THA thing

 

Darn, I just started envy you now......

 

Don't tell me I'm wrong when you have no idea what you're talking about. There are 2 obstacles to overcome in overclocking: stability and thermal. A majority of people run into stability issues on stock voltages before they run into thermal issues. Those of us who can't OC our 5870's to 900/1200 aren't starting fires in the process. It has little to do with heat and everything to do with chip stability at those frequencies and voltages. More stable chips can handle higher frequencies, and given a little more voltage can handle quite a bit more frequencies without crashing. Once you've started uping your voltages, you can probably start worrying about the thermal limits of your chip.
