Hi Hi Hi, been reading these threads for awhile now and finally decided to join in.
Setup for benchmark:
4xSapphire 7950 10032-4L @ 1170/1570 in CCC
i7 3930k @ 4.6Ghz
Freezer blocks on my GPU radiator during runs
3536 was the highest I could push these without the screen locking up during my runs. Unfortunately I did not get a screenshot with it running. Just the saved file, oh well. It doesn't make much of a difference anyway.
Perhaps the system might be a bit more stable at higher clocks if I reduced the amount of RAM used while running this bench or maybe lowered the speed of it. Increasing the CPU clock did seem to have an effect on my score, but not a more than a change of 25pts for every 200MHz above 3800.
I tried using Trixx to run the clocks on the cards higher as the Hynix RAM modules on these cards should be able to take more than what the max is in CCC, but when running Heaven it didn't recognize the settings of 1400/1800 and instead ran it and scored it as though I was at 925/whatever teh stock memory is. It seems that CCC on these cards are limited by what would be safe on Elpida memory but that I have a lot of room unused on the Hynix.
I'm sure I still have some tweaking left to do on my CPU primary and secondary voltages.
System specs are:
ASUS Rampage IV Extreme mobo with EK MB Blocks on Bios 4804
Quad Fire 7950HD with EK waterblocks
Platimax 1350W PSU
64GB G.Skill RipjawZ 2133MHz memory kit
Corsair H100i for CPU
Phobya 400mm X-treme radiatior with 200mm BitFenix all black fans
Kingston 120Gb SSD
WD red 3tb HDD
Thermaltake level 10GT case (annoying LEDs removed)
Other bits and pieces
I think I am at about as far as I bother pushing this system. My pockets are not deep enough to get R9 290x's and then the waterblocks that go on them, plus I haven't even received the EK back plates that I ordered a couple weeks ago. I think I will mostly work on aesthetics of the system from here forward. The cable sleeving from the PSU are not the best looking and do not come up far enough to the connectors. The majority of the cabling is hidden so what is primarily seen is the wires that extend beyond the sleeve. I may switch out the 18ga wires with 16ga when I get around to redoing them. I only have flexible hose in my system but now that I am pretty settled on the routing of the water lines, I will move to acrylic soon. Just need the money to buy the extra fittings as I currently use 12 compression fittings. I do have a nice Steinel ESD safe digital heatgun programmable in 10 degree F increments so dealing with acrylic should be no problem. I digress, this thread is about GPU performance and I really don't have anywhere left to go unless I can figure out how to get past the 1200/1575 limits. These cards should be unlocked, but as of yet I cannot get past the 1200/1575 +20 power limits. I might not want to go past +20 power until increase my PSU PCIE power wire gauge anyway.
