harryob Posted March 24, 2013 Share Posted March 24, 2013 Ran a few tests. I'm able to get the core up to 1004 (+350) with memory at 2450 (+650) for a 3d Mark of 6170 vs a stock 3d Mark of 4269. At those settings the temp maxes at 87 deg C . I know people have pushed the memory higher, but I've only seen minor improvements with it up to 825 and I got artifacts as low at +700 on one of the PCs so I'm going to call it good at +650. I think +350 on the core clock seems like it's already pushing my luck, but I might try higher just for testing. Quote Link to comment Share on other sites More sharing options...
harryob Posted March 24, 2013 Share Posted March 24, 2013 Seems like my limit is somewhere between +400 and +450. At 450 the driver crashes. Anyway, this is the most stable run I got at +400. The temp did peak at +90, do you guys think that's ok for daily use or should I ratchet it back for a lower temp? Quote Link to comment Share on other sites More sharing options...
roo7y82 Posted March 24, 2013 Share Posted March 24, 2013 @svl7 hey hope you doing well ? any news of vbios for our 670mx ? i uploaded my bios 1 month ago for you. thanks for your help regardes from france Quote Link to comment Share on other sites More sharing options...
elmo Posted March 25, 2013 Share Posted March 25, 2013 can I ask what you did to get it working? as I'm currently stuck with the 256byte mismatch errorI first had a couple issues also. I flashed the wrong one (4gb one) and thats why it first wasn't working. But the card still worked sense I didn't turn the computer off yet. Before I even turned it off when I tried to pull the vbios it came out as a 0kb file, and GPU Z showed like it didn't ever recognize the card and had no specs on it after I turned the computer off and back on, and on top of that it would't even work, it wasn't even recognized by windows. This is when I tried flashing the vbios again for the 2gb. I think it working had something to do with wiping the card of the vbios fist so it was blank, the flashing the bios on the blank card. It when through fine as a blank card. I think there is a option for this nvflash. Quote Link to comment Share on other sites More sharing options...
heywheelie Posted March 25, 2013 Share Posted March 25, 2013 Pardon the newbie question, but what is the latest vbios for the Dell 680m.I have an alienware M18x R2 w2ith 2 x 680m and vbios 80.04.33.00.32Is there a later one? Quote Link to comment Share on other sites More sharing options...

svl7 Posted March 25, 2013 Author Share Posted March 25, 2013 I don't quite understand which vBIOS I should download for the best performance. There's one Clevo version on the first post and 3 Clevo versions with seemingly different voltages on the second post in the attachment section. Which is the latest release and the one I should download? Use the 33.10 version. The temp did peak at +90, do you guys think that's ok for daily use or should I ratchet it back for a lower temp? That's too hot for my taste. I take it you have a Clevo system? This card should run cooler provided the heatsink applies enough pressure on the GPU die. @svl7 hey hope you doing well ? any news of vbios for our 670mx ? i uploaded my bios 1 month ago for you. Ah right, pardon, I'll upload it asap. Write me again if it isn't here in the next couple of days. it still wont flash What did you try so far?

This card should run cooler provided the heatsink applies enough pressure on the GPU die.Yes it's a Clevo. The first run seems to have been an anomoly, it's peaking at 85 degrees C now with the average temp about 80 with gaming use and in the benchmarks at +400 MHZ. Looks like the absolute max I can get it to benchmark at is +405 before the driver will crash. I'm thinking of running it at +375 for daily use to provide a little more margin of error.

buluunee Posted March 25, 2013 Share Posted March 25, 2013 i still think thats bit hot coz i have never seen more than 74C in full benchmark with demo and thats with +450 core +830 memory. with mild OC in benchmark it usually sits around 69C. you can expect to see some overheating with games on that OC. most of late 2012 and 2013 games run 10C hotter than benhcmark. and also, i would not recommend you to OC your gpu more than 200 on core and 400 on memory for daily usage. as for me i do not OC my nb for games coz atm its sufficient enough to have fun with the latest games and my temps maxes out 83C on tomb raider 2013 on High setting which gives me very playable 40 fps and i could also push my turbo fan feature to lower my temps untill 65C so i think thats overheating as for your nb Quote Link to comment Share on other sites More sharing options...
Captmario Posted March 25, 2013 Share Posted March 25, 2013 ive been trying to search around for a know-how on backing up your old vBios, just incase new one gives any problem?do you know how to backup the present vbios because im waiting to upgrade my vbios with one of svl's modded bios. just to be on the safe side Quote Link to comment Share on other sites More sharing options...
harryob Posted March 26, 2013 Share Posted March 26, 2013 I think the 15inch Clevo models just run hotter. Even with no overclock, I'm hitting 89-90 degrees with Kombuste after 5-10 minutes. My temps in actual games seems to peak at about 85 regardless of overclock unless I push it all the way to +400 GPU. If I do that the temp will hit 90 in games.

It might not work with FreeDOS. Also if nothing helps you can try the windows version of nvflash. Quote Link to comment Share on other sites More sharing options...
nfshp253 Posted March 26, 2013 Share Posted March 26, 2013 Thanks, svl7. I assume the voltages you provided have been tested to some degree and extent. Quote Link to comment Share on other sites More sharing options...
harryob Posted March 26, 2013 Share Posted March 26, 2013 Don't use Kombustor or Furmark or similar tools... at least not if you want a working GPU.Got it. I didn't realize how bad kombuster could be, but at least it proves that the throttling is working to limit the max temp to 90. I reduced the overclock to +375 core / +400 mem and get a 3D Mark score of ~6250 with a max temp during the benchmark of 78. I'm pretty happy with that, although Heaven Benchmark still peaks at 83. The averages during both tests are about 5-7 degrees lower than the max. I can of course max the fans and drop the temp quite a bit, but that seems wasteful and very loud.

Captmario Posted March 26, 2013 Share Posted March 26, 2013 So basically if i flash with a vBios and i happen to have a brick ( just assumption ).. how do i unbrick it? Will optimus help since there will be a second card namely intel hd 4000. Quote Link to comment Share on other sites More sharing options...

HighBounce Posted March 27, 2013 Share Posted March 27, 2013 has svl7 done a vbios mod for the clevo k3000m? Quote Link to comment Share on other sites More sharing options...
Toopy Posted March 27, 2013 Share Posted March 27, 2013 Probably it's not flashing. Make sure your machine has the latest EC and BIOS on it. Did you use MS DOS or FreeDOS? It might not work with FreeDOS. Also if nothing helps you can try the windows version of nvflash.Using MSDOS, swapped back from prema's mod to the latest Clevo BIOS (which had never been on the machine before as it had the Horize BIOS), still didn't flash. back to premas mod still wont flash. I have a feeling that the #WP pin on the flash chip is enabled in hardware. I'm away from home at the moment so I don't have a any tools to check. Hopefully that's what the problem is which shouldn't be to hard to overcome. I also wonder if they are using a newer flash chip and nvflash only partially supports this one. Once I ope it up I'll check. Quote Link to comment Share on other sites More sharing options...

setonfire Posted April 3, 2013 Share Posted April 3, 2013 Guys how far can or should I push the oc on my 680m ? Till you don't sniff an acrid smell (kidding) Well... until the temperature stays below 90C, you don't have artifacts and your driver doesn't crash.

If I have no intention to oc the 680m, would it be wise to flash the vbios?2. If I flash the vbios, should I re-enter my win 8 serial number?Any advices would be appreciated.Thank you.
