Ok, next question. I got the GTX 465 working perfectly (so far) on a different system. I got the black version and everything I read says that the BIOS can be flashed to a GTX 470 with no problem. The "bar" in MSI Afterburned starts at 607MHz and goes all the way up to 916MHz core freq. Tried running it up to 916MHz but when I did, the sensors told me it had actually down clocked to 403MHz and the PG WUs ran alot slower so I set it to 700MHz and it crunches units in 16 minutes. So this leads me to conclude that once I get the card BIOS flashed, I should be able to OC this thing to its full potential. Oh yeah, there was a question.....I have never flashed a BIOS on a video card before so I was wondering if anyone had some guidance for me?

@Dan - Nice work! I like that plan. How many machines are you running?

@Joker - I found this link that may help...

Actually, the reason the card clocked down when you tried to set it to max speed is because it crashed. It's part of their built in safety features. The reason it clocked down could be that at 916MHz, cooling wasn't adequate and after it reached 105C, which may have only taken a couple seconds, it immediately lowered the frequency to keep from frying itself. It could also be that the voltage didn't support the card running that fast and every computation it did errored out. Changing the BIOS may not solve this issue, as it normally happens for physical reasons instead of software.

If the voltage was increased to support that speed, then it's very possible you had electron jumping within the chip that also would cause everything to error out. Just because it allows you to overclock by 50% doesn't mean it'll be stable at 50%.

Thx Max. That post is from 2007 so it is still applicable to modern cards?

+1 to what JPM said - just because the software lets you, doesn't mean you should overclock that high. For my 5970s, Afterburner lets me go up to 1000, but I've never gotten it stable above 850 (currently at 825). I would suggest starting from stock, then going up in small (~20MHz) increments, checking temps, WU errors, etc. along the way.

And I believe what the BIOS flash does is unlocks extra shaders/cores (I may be wrong - someone correct me if I am) on the card. The clock is a separate issue...

EDIT: I think it is, joker, but here is a better link, I think...

Good info JPM. I am more looking for the BIOS update to increase my stream processors. I have read that a flash (with this card) will increase/unlock them from 352 to 448. Dont know if this is true or not but I would like to find out. That would be a pretty good OC in and of itself and any MHz increase would be a bonus.

I think you are right Max as far as the BIOS flash.

I'm running two i7 boxes with Bonic running 24X7, except when I'm gaming.

Now something new. Every time my screen saver kicks in, the WUs take hours then get a computational error. Anyone ever have this problem?

[DrPop]

huh....must be screwing up the data somehow. I NEVER have a screen saver - it takes some CPU power that could be going to my BOINC account! heh! I always just go into the power settings and make it turn off the monitor after 5 min.
See if that works for you, maybe?

[joker]

Life is not that easy for me right now. I used to have the monitor turn off but then one day, for some reason I have yet to figure out, me monitor would not turn off. That message that tells you that your monitor is working but is getting no signal would just stay on the screen. dont want that burning into the screen. Ok, I say FU, i'll just turn off the monitor! Power switch on the monitor went goofy after about the third time I turned it off and it took me 10 minutes of pounding on the key to finally get it to come back on so I dare not turn it off again. And on top of it, I decided to switch 5830 cards in the machine that is giving my trouble to see if that would fix it and now I cant get Crossfire or dummy plug to work. Windows, MSI afterburner and GPU-Z all tell me that there are 2 cards but CCC just refuses to find the second card and so BOINC is only using one of them.
