M17x-R2 vbios

Hello, if anybody has, or is able to take a screen shot of rbe with their mr5870 voltages and clocks page, I would greatly appreciate it. I'm not planning on overclocking my 5870, so I'm looking to get it to the Dell voltages, which seem perfectly stable. I'm aware that there's plenty of information on this, but having it all in one place with the exact placement for where to change each voltage goes would be helpful.

Thanks!

Edit: another thing that would also work is if anyone knows what the values of .95 (on a normal mr5870) go to (I believe it's .9, but I'm not positive). I already know that anything that's 1.15 goes down to 1.05.

Edit number two: I went ahead and flashed the vbios only changing the highest of the voltages and leaving the lower voltages clock voltages unchanged.

 

Value of about 90-95 from the original voltage of 1.15 is what the G73JH owners did and they literally get almost 4 hours of battery life with it.

 

That's an amazing undervolt! I'll have to make a new vbios to try out more voltages. I already have my temperatures managed, with my maximum being 78 Celsius on the memory, but I'm definitely going to try this. If there's a chance that 700/1000 is stable at .9/.95, I might even try lowering the other clocks a bit. The only issue is I don't think I have powerplay enabled. I need to go check on that.

Thanks for the input! +rep

 

Hey what's up thanks for the rep! I have been a bit busy sorry for not replying. Anyway How is your testing going? Any BSODS? What is your current highest and lowest clock? How is your battery life also? Which is what would be awesome if you can have like 4 hours, the G73JH owners get like about 3 hours which is really good, of course i do a different testing of screen brightness almost all the way down and wifi turned off while in class that's my test and of course extra battery life with a high contrast theme.

 

I found out my blue screens were software related after I bricked the card with a bad vbios flash. This means it was definitely okay down to 1.05, and .9 was too far.

That card limit for stock clocks was around .95-1.

 

Hmm interesting, looks like each card is different but then again the Asus ones are reversed backwards, and the alienwares are not. Sucks you can't go lower be awesome to get some good battery life, and custom drivers finally.

 

I just undervolted my 3D clocks to 0.95v and the rest to 0.8v. So far it's very stable, it can handle furmark's xtreme burn no problem at 1920x1200.

 

I expect .95 to be stable on the card I had, since .90 wasn't stable, but only resulted in a driver crash and not a blue screen or an immediate shut down.

If I'm not able to get a replacement card for whatever reason, is there anybody with an M17x-R1 who'd like to bring this Clevo MR 5870 with either MSI or Dell vbios (lol) back to life? All I would need is the original vbios to be reflashed (I saved them, and I also have a flash drive prepared to boot and flash from) and then I can resume flashing myself with only the vbios from that card (I wasn't sure if MSI/Dell/other MR5870 vbios would flash properly, but I tried it anyways).
