Title: Gaming vs mining clock speeds and volts Post by: SMOKEU on August 12, 2012, 11:00:21 AM I'm finding that with my shader unlock 6950 I need more voltage for the same clock speeds to be stable in BF3. Usually I run 930MHz @ 1.200V for mining, and it's stable at that all day using -v -w 128 flags, but for BF3 it keeps crashing even at stock memory clocks so I have to either increase the voltage or decrease the core clock speed. I thought that mining would place a lot more stress on the card than gaming, and therefore present stability issues more quickly than gaming. The card is otherwise fine.

BF3 dosen't like overclocking on most systems,be it vid card,CPU,RAM or Front Side Bus :( The 6950 (unlocked shaders by soldering a wire) I have on my second gameing puter only likes to play BF3 @ 900 core clock & 800 or higher mem clock,no overvolt. My 6970 crossfire setup is the exception-925 core clock & stock mem clock,20% Power Control Setting works well in game & gives me 422 mh/s per card ;D I had my 965 CPU up to 4.2 & my RAM OC'ed to 1880mhz,but BF3 would stutter pretty bad until I reverted back to stock settings :( Title: Re: Gaming vs mining clock speeds and volts Post by: racerguy on August 13, 2012, 03:36:15 AM I always found mining could take a much higher core clock than gaming, usually just reset my 5770 back to default settings using trixx before gaming.

Did you solder the wire to enable writing to the BIOS EPROM? Or is there a new hack that I am not aware of?

Did you solder the wire to enable writing to the BIOS EPROM? Or is there a new hack that I am not aware of? I borrowed the card from my bro,who did the deed.I redid the thermal paste & saw a wire soldered on a chip,don't know what the chip is.But it is on the lower left of the GPU chip. This is the card: http://www.newegg.com/Product/Product.aspx?Item=N82E16814150530&Tpk=XFX%20HD-695X-CNFC%20Radeon&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-na-_-na-_-na&AID=10446076&PID=4176827&SID=810tmmxwkltw Found the info: http://forums.extremeoverclocking.com/showthread.php?s=d7d12b7c72ef64011363d4914d416242&t=355592 http://i63.photobucket.com/albums/h148/Bigblock462/6950shaderunlock.jpg Be sure to use a shorter wire,as when fitting the heatsink back on,it will get in the way & possibly keep it from seating properly.We used a piece of paper/sticker to "insulate" it from the heatsink. BTW,this WILL void your warranty !!!!!!!!!! Title: Re: Gaming vs mining clock speeds and volts Post by: GenTarkin on August 14, 2012, 05:59:52 AM Yes , gaming actually puts stress on MORE areas of the video card than mining does. Mining stresses the shaders the most, but gaming also stresses the VRAM, VRAM controller, the ROP's and other key areas of the GPU itself that mining hardly touches at all.
This is why gaming in general results being stable at lower clocks / higher voltages than mining. |
