I was told to not use the stock heatsink and fan if I want to overclock. The only reason I didn't get another heatsink/fan is because I didn't want to have to apply the thermal paste, but after seeing some videos of how to apply it I feel I can do it. The power supply is apparently enough for a one graphic card setup, but I'd need to get a 1000-1200W when I decide to try crossfire. When that time comes is when I'd be willing to overclock if the stock heatsink/fan won't cut it. What do you all think? Around christmas and maybe a little ways afterwards when thngs go on sale and I can snag another 4870, power supply, and heatsink/fan for cheap is when I was thinking. Any reccomended heatsink/fans? Thanks a lot.
That psu is WAY MORE than enough to handle a 4870 Crossfire.
However, That Mobo will not handle the 4870 Crossfire well.
I would recommend selling the 4870 when the time comes and getting a 4870x2 or GTX280 or whatever may be the top of the line card at the time.
The reason is that the PCIE-E Slots drop from 16x to 8x when you do Crossfire. In some cases, the 4850 gets limited. The Faster 4870 would be even more limited. The Result is that in some cases you could see a noted drop in performance if a game does not use CF well since each individual card would run slower than a single card.
I have that motherboard, it let me attain 3.6ghz with that processor and a Xiggy HDT S1283. The first thing you want to know is your VID, so download coretemp or realtemp.
Once you know that, you will use it as your first voltage. My Q6600 has a VID of 1.300V.
You will want to overclock in steps, so maybe 100mhz at a time. At each step, check your stability with prime95, if it passes after about 30 minutes or so, your probably ok. I was too impatient for this, so my first OC of the CPU was to 3ghz, or 333 x 9. It worked great at 1.30V.
So I stepped it up to 3.2ghz, or 400 x 8. It crashed after 10 minutes of prime 95, so I added voltage. Took it up .05V to 1.35V. It turned out to be stable. So I took it up to 3.4ghz, added voltage, yada yada.
Eventually, I was able to reach 3.6ghz (400 x 9) at 1.48125V. I don't leave it clocked that high though, because thats a lot of voltage and 3.2ghz its good enough for me. Just about as fast as the highest clocked CPU intel offers.
