Clevo 5870 flashed to Dell 5850?

Exactly as the title says. I'm picking up an M15x with a Clevo 5870, and I wondered if it is possible to flash the card with the Dell 5850 VBIOS. I know it would be slower, but I figured it would be less hassle then having to use the ATI GPU Clock Tool, and I can always OC it past 5870 clocks anyways. Thanks!

 

No idea, it's generally not a good idea to flash a vbios to a card which isn't made for it... You may end up with a brick.

Anyway, I don't understand what the advantage would be... ?

 

nope, afaik the ppl who tried to flash a dell bios on the clevo's for the 5xxx series got it bricked.

 

The only advantage would be that I wouldn't have to use the Clock Tool, and it could be more easily sellable, in the future. I don't think I will, though, if most were bricked. Not worth the risk.

 

For what do you need the clock tool with this card?

 

The user I'm buying it from says that you have to use the clock tool to get it to run at non 3D clocks. Is he mistaken? Sorry for the trouble, I didn't take the time to read the entire thread on the 5870 in the m15x.

 

Never had a 5870m in my system, but I always thought it runs fine, no adjusting needed. If I remember correctly, the only problem with the Clevo 5870m is that powerplay doesn't work, so it won't clock down... idles at 3d clocks.
I'm sure someone here as more experience with this and can help you.

Maybe you can flash the Dell 5870m vbios on it, but don't count on it, I don't know whether this has been tried.

 

I think Mandrake, and maybe Inap, tried flashing the Dell vbios to a Clevo 5870M back when people were transplanting 5870M's into the M15x before the 5850M was available. The motive was to get PowerPlay and Overdrive, neither of which were available with the Clevo bios. It failed, and the cards became paper weights after various recovery attempts proved unsuccessful. Don't do it.

 

Yeah, thats what he said, idled at 3D clocks. I'd need the clock tool to get it to run at 2D or idle clocks. I tihnk I'd also try some super low clocks to see if I could save some power. The Dell 5870 BIOS could be a good idea...

 

Rev, thanks for the info. Definitely won't try it, hah. Is it possible to go OC the card with the GPU Clock tool?

 

Yes. In fact, that was its original purpose. You can create shortcuts that execute Clock Tool with embedded command line arguments to set the clocks to whatever you desire.

 

That's what I plan to do. Just have 4, most likely. Stock Idle, Stock 3D, OC, and something like 25/50 maybe, if it works, for ridiculous power savings.

 

just be aware, some low clock settings for the ram may cause artifacts and/or crashing.

mine didn't like 200mhz on the ram and would go all glitchy, making usage impossible.... but 100mhz was fine.

the command line for shortcuts is as follows
" C:\Program Files (x86)\AMD GPU Clock Tool\AMDGPUClockTool.exe" -eng=700 -mem=1000"
replace the numbers with what clocks you want, eng being core and mem being memory obviously. if you combine it with watto's " stealth mode indicator" it's possible to turn your stealth mode into a 2d/3d clock toggle. i did this ages ago but can't find where i posted the files.

also, another thing i noticed was that with low clock settings, youtube (with hw acceleration enabled) would green screen making the video unwatchable, any attempt to play a second time would result in a BSOD. I HAD to swap to 3d clocks before watching youtube (or disable HW acceleration in youtube)

 

Thanks for the tips! I'll try the stealth mode trick when I get it. I'll try to find how low the clocks can go. Youtube does the exact same thing when I try to play videos on the M11x R1 IGP, but never BSOD's, just gets annoying. Also, for the OC, I hope to hit 5770 clocks.

 

Sapphire Trixx work for you? It did with my Clevo 5870m. You can just flash to 100/150 0.9v, then use Trixx to change the clocks and voltage for gaming.

 

Don't know, lol. Don't have the laptop yet. I'll try it, what exactly is Sapphire Trixx? I always thought it was just an OC program.

 

It is, but it also has voltage control.

 

Ahh, okay. Thanks. I really want to have it run at as low voltagea and clocks as possible, since I know the m15x has no battery life.

 

before modding the bios, make sure the card is happy at those settings.
use sapphire trixx and test them out first.

last thing you want is a looping BSOD or having to flash the card blind.

 

I've had that happen before, BIOS moddig a 3870. BSOD looped unless in safe mode. What would I mod the BIOS for? I wouldn't think that would work, since even if I set low idle clocks, it wouldn't go there because it "idles" at 3D clocks.
