1/14/2024 0 Comments Cgminer 3.1.1Ok think i'll keep the 6950, 5770 in my main pc. Might switch it around with the 5770 so it not sucking in hot air off the back off the 5770. Have to use the auto-gpu option to try and keep the temps down. The 6950 overheats like a mofo and isn't even o/c. Ok just finished installing etc the fm2 asrock board into my main pc, its running a 7xxx series apu, 6950 (shaders unlocked) and a 5770. Mobo: Asrock Z77 Extreme9, $340 : Extreme9/Ĭase has 9 expansion slots, motherboard supports trifire (cards won't actually be running in trifire) and I can effectively take up 3 expansion slots per GPU which will allow enough cooling. What you guys rekon of this for trifire miner? Since cards aren't running at high volts (below stock even) and not much more faster than stock speeds, its hoped their temps won't be that bad. If so it should make a 3 GPU setup possible even with barely there gaps between gpus. Now testing to see at stock or with only a modest overclock and lowish volts if I can get an avg hash of 1.2Mh/sec (over 24hrs). As I don't have it installed now and previous drivers that worked would crash (at stock settings hash rate = 1.131 Mh/sec. I think the app sdk was causing cgminer to crash the driver. I'll be happy with 600Kh/sec per card 1.095 means temps will be fine and power consumption low. Ok I'm running stock clocks - 925/1250 non stock undervolt 1.095, going to run it overnight to see what my avg hash is.Ĭurious to see if my o/c really is offering much which I suspect its not. I guess there is only one way to find out! I can only hope they have a well developed windows 7 64bit driver and it'll work with cgminer and see the extra gpus. From the looks of it, it uses a pci-e controller card you put into a PCI-E on a host PC's motherboard which then drives the expansion system. That said if I'm going to bother with 7990s I should just look at importing one of them PCI-e expansion systems. I don't think newegg ships internationally anyone know of a good US online ship to get some bargain 7990s from? Tho to try and maximise my hashing, might import some 7990s as a "cheat" to get more than 2 gpus in there. If I end up buying the maximus board and it doesnt' work out, guess I'll be building another mining rig that only takes two gpus. Was at 1125 vddc but now at 1118 vddc i get a saving of about 2C. So far at 1000 engine, 1200 memory (won't drop below that if u try just reverts to 1250) and 1118 vddc. ![]() Playing with the o/c to see how low on gpu/mem/vddc I can go before I drop under 1.2Mh/sec. ![]() Basically gpu 0 sits on 75c and gpu 1 sits on 65C. On another note man there must be a big "heat cloud" around gpu0 as its like 10C hotter than gpu 1.īoth cards have a decent amount of room between each other and two 140mm fans on the front blowing cold air at them with the lid of the case off. Afterburner doesn't work even with the overclocking options enabled, yet Trixx works. There are only sapphire 7950s (two of them).
