BIOS modding for GPU OC fun and profit!!

That's a good thing and perfectly normal that your temps went up. Correct me if I'm wrong, but it means your CPU is working harder now to keep up with the GPU. The GPU is easily still the bottleneck for games, but it allows the CPU to do more now. And since they share a heatsink, some of that temperature will spill from the CPU to the GPU.

My CPU is fine (PHEW! If that got any hotter...!) only my GPU is affected but 81C isnt so bad is it? did not apply new paste or remove vent filter yet. btw that is the clear film over the intake right?

81C is a bit warm, but nothing dangerous. If it is only 2C above your old max, then it's a normal increase. If you start exceeding 84C, then it might start throttling, but you won't damage anything until you're 100C or higher.

If I were you, I'd try removing the vent dust filter (yes, it's the black plastic mesh film over the intake), and see if that drops you back below 80C, which is should.

Oh my freaking god, seeker!!!! after 2 hours hours of L4D2, it hit 86 on my CPU and 85 on the GPU! So bad! I was thinking there was damage until you said it can go up to 100C. It knows when is too much right? I dont want my computer to die
Im scared to remove my dust filter. my house is always dusty and i dont want my computer to explode.

The dust filter doesn't do much of anything anyway, except clog up with dust and restrict airflow. You should really clean out the heatsink/fan with compressed air at least once a month, whether you have the filter attached or not. I'd remove your bottom cover, clean the dust filter, spray out the heatsink, and try again. Then re-check temps, they might improve just on the cleaning.

Yeah, overheating isn't as big of a deal on laptops as most people think. The BIOS will shut your computer down before it allows any damage to occur. A lot of people coming from the desktop world don't understand that while 60C is alot on a desktop part, it's quite cool on a notebook, which has to deal with much weaker cooling solutions. Nearly all mobile chips (CPU or GPU) can handle 100-110C temps before damage sets in, though the Dell will start to throttle at around 84-ish, and will likely shut you down in the mid-90s.

seeker! :-) can you make a modded bios set for clocks 800/1050 for the 5730 A12? Thanks! :-)

I think that is what Seeker is using right now according to his sig. 750/1000 is already hot enough imo.
would 700/1000 be a lot more cooler? thats the 5870's speed!
I just looked at my vent and its dusty. I just cleaned it with compressed air too! I hate it when my computer enters the 70sC(but acceptable) and i REALLY hate it when it gets to 80C

Aw man the temps are ridiculous! Id like to try a 700/1000 5730 if you have that made already

Yeah, but the 5870 has twice the shaders and pipelines as the 5730 does (800/32 vs 400/16), so even if the clocks are the same the performance isn't even close. At 835/1100 I benchmark around the same as a stock 5830, but even that's far behind the *70.

How much did your temps drop when you dusted it out? You should be fine. If you want to keep your temps in the mid-70s, even under heavy stress test loads, you're going to be better off removing the dust filter and changing the thermal paste, than lowering clocks. Doing the filter/paste will drop your load temps by at least 5C, and as you said, your temps only increased by 2C with the OC.

If you really want to drop your OC clocks, instead of changing to a arbitrary new number, try testing out different clock settings with GPU-Z, then letting me know what works. That'll be a lot easier than constantly re-flashing your BIOS.

Here you go.

I understand that it will never perform as good because of the pipelines. I just thought I could base my speeds off that. i will stay on ur speed, but i really need to clean it. i have not cleaned it yet because i ran out of compressed air

If your heatsink/fan is dust clogged, then cleaning it out will help your temps significantly. Clean it out, test new clocks, and let me know.

Here's something a little lower if you think you really need it 1645_A12_715_940.zip
