Eh heaven isn't really good for temp testing or stability. It's better as a benchmark. Those 'awesome overclocks' and 'runs so cool' will quickly turn to 'my card is poop!' and 'why is my card on fire?' on OCCT Error test or other fur-based stress tests like furmark.
I left on the VRM and memory cooling that Sapphire had on (it was pretty good actually). Max VRM temp was 83 during this run. Core voltage was 1112mv (I have a very high ASIC score so I only need really low voltages to keep overclocks stable). I normally go about with 1100mhz on the core at 1031mv which is fantastic for temps. In fact, if I go to stock speed (950mhz) I am stable at 924mv, which is AMAZING for cooling (sub 50 degree Valley runs).
I'm sorry, I'm really confused what overclocks you do. You keep saying like 3 different voltages and then never mentioning the clock speed. 1.112v for what core clock?
What model card are you on? You say sapphire but sapphire has literally at least 6 models sold in at least 10 uniquely different iterations.
And what cooler is this on exactly? The accelero hybrid or accelero with 3x fans? I assumed you meant the air cooler but relooking at your post I realized there's 2 different accelero 7970 coolers.
I can OC the RAM a bit if I overvolt it to 1.7v, but what's the point really, minimal gains, f*ck you Elpida.
In GPGPU applications, which is what most 7950s are used for (maybe not as much recently but still a large percentage), RAM overclocking actually is more important than Core overclocking, as in per mhz gained in ram is a bigger boost in performance than core. Total opposite of gaming, but ~100mhz in gaming can still give you a good 1-2fps gain in gaming at larger resolutions.
1.7v, is that what's considered safe? I always thought ~1.65v is what's considered the max. Thinking on it, I guess that's likely due to the VRM more than the DDR3 based GDDR5 ram, with GPUs tending to use crappy components and limited real estate. I guess if you can keep your GPU VRM cool, 1.7v should be perfectly fine. I just recall people saying blow outs at 1.7v and lots of people saying never, ever go above 1.65v. As long as you have a heatsink on the GPU VRAM VRM though i guess.
83*C is pretty hot for VRM, I usually worry about VRMs going over 80-90C depending on the model. And with sapphire I'm not so sure I'd go over 80. If you don't hear coil whine then whatever.
. Core voltage was 1112mv (I have a very high ASIC score so I only need really low voltages to keep overclocks stable).
Did we come to a conclusion on ASICS? As far as I understood, ASIC meant absolutely nothing at all... If you only need low voltages to be stable that's your core's binning, not the electronics on it. Good electronics will account for maybe .1v, not anything dramatic. And it's more like better voltage regulation than actually using less voltage.
I just cut my panel last night. Scratched it =(
How can I fix the scratch??
Ah, trying to cut corner will always just bite you in the butt. Now you'll have to spend 3x as much time as you spent doing the cutting, repairing the damage. I did the same thing on this build too though. It really sucks ;/
It depends how bad and deep the scratch is. If it's not too deep, just put some paint on it. I've tried about a dozen acrylics (ie those you find at craft shops), about 2 dozen different spray paints, and a half dozen other things (paint pens, hobby paints, etc), and it's quite hard to find the perfect mix, as you need both the perfect color and
The closest I've come, is Warhammer Black paint, which I believe is slightly too flat but you can only tell at an angle and even then it's not very noticeable even in bright lighting. If the scratch has some depth to it, you are going to need to fill it a bit. As for that, I can't say I've found an optimal solution on that, I'm sure some sort of putty would work fine. You can easily find warhammer paint at a local hobby store (like any place that'd sell magic cards or models).
Powder coating is such a unique way to applying color that the only way to fix a scratch on a powder coated item, is to just powder coat it. You can get it done for i think ~$50 at a local powder coating place though. There are so many scratches in my current build that I just stick with warhammer paint. Interior scratches, scratches on edges and stuff I cut, that is, only that one scratch on anywhere major.Edited by Belial - 11/8/13 at 4:30am
