Hi everyone. I have model # ZSFC. Anytime i try to up the GPU core on this thing even like 20MHz I will start getting artifacts pretty soon after just from simply windows browsing. I am using CCC for this. Is there another program i should use? Does my card just suck for overclocking? I even installed a side fan to blow right on this bad boy. Any suggestions or similar problems?
well the one thing i noticed with my card that any program i use will not display any voltages. Is it impossible for me to overclock without increasing the voltages a bit? also. CCC has automatic fan speed that seems to adjust with the temperature. Are you suggesting I permanently put my fans on a 50% setting or higher?
I've never flashed a different BIOS to a video card out of fear. How risky is this? Hav you used this pencil volt mod and had success with it? I am at 875/1000 now and its been stable for a few days now. Did you have to increase voltages just to get to 890?
thanks...yea I would prolly need some aftermarket cooling if I was gonna mess with the voltages. another thing i've never installed. I did consider at least taking the card apart and applying some arctic silver 5, but wasn't sure which spots to apply it to. Would you by chance have some type of diagram for that procedure, and maybe explain how to take apart this specific card? thanks
good tutorial. Well if you do this with your 4890..take some pics..I would really appreciate it! I am definitely interested in trying this. I got a nice tube of AS5 sitting here from my last build!You have the ZSFC model correct?
I'm having some issues with my card presently, so before I go ahead and redo the Thermal Compound, I want to make sure that it won't void my warranty, as my card Errors out with 81 Errors on STOCK CLOCKS in OCCT. :-/
I'm going to see if maybe I can RMA it for a better revision, as this is kind of the last straw... I love XFX, but these Non-Reference cards are such a pain!
Here are some pics of me replacing the thermal compound with Arctic Silver 5 on my Sapphire 4890 Toxic (this is a reference board with Sapphire's aftermarket cooler). Simply unscrew (make sure you put them back in the same order, so take a picture or organize your screws), it will take a little force to seperate the heatsink from the GPU so don't be afraid, I used ArctiClean to remove the old paste, re-applied AS-5, and put it back on. Make sure not to work around carpet and if you do, don't scuffle your feet or anything to create static. Apply the paste the same way you would a CPU, less is more. That's about all the tips I can give from my experience.
