GA-P35-DS3L OC Time!

[BALISTX]

A friend is using an AC7 Pro and has his E2180 OCed from 2.0 to 2.6 and temps are well under 60C under load.

I have a good idea what the AC7 can do, but we're talking about a Quad oc'ed at 3.0. I don't think an AC7 is enough under load.

Has anyone modded a ACF64P? I am thinking of getting one, lapping it, and installing it with screws and a back plate, as well as putting a better fan on it....what do you think I should expect temp wise?

John: I know the Q6600 would be a different story and it would work for a moderate OC. But I was referring to the previous post when the poster (sorry forget name) heard that the AC7 Pro was not good any OCing at all.

The Ultima-90 might be a good alternative.

Sorry Jerry, didn't read that part...

OP, the AC7 is a great budget cooler. But for a Q6600 at 3.0, it might be asking a little too much of it. I've been reading on Q6600 air cooling (which I don't know much), and most 3.2-3.6 oc are done with a Tuniq or a TRUE 120. A Zalman 9700 could do the trick too.

Ohhh.... I still have mine, along with an E6400. Once I build my new rig I will use the AC7 and will surely try that!

I had my q6600 with AC pro 7 at 3.6 Ghz at 1.38 vcore with load temp 57C in the antec 900 case before i switched to water. I made the rear fan a blower instead of exhaust. That helped a lot.

How many case fans did you have in that rig?

I also have a question regarding gigabyte boards' memory multiplier vs memory ratio in OCing guides. I'm mathematically challenged and can't figure out the relationship between the two. What translates to a 1:1 ratio, 2:1, etc?

[3.0charlie]

Memory multis.

1:1 = 2.0 in BIOS
2:1 = 4.0 in BIOS

and everything in between.

Yeah 2.0 = 1:1. It means the RAM is running at 2x the FSB. All you have to do is divide the higher # by 2...like so:

2.0 = 1:1 ............FSB 333 = RAM-333 = DDR 667(53/5400)
2.4 = 1.2 or 5:6....FSB 333 = RAM-400 = DDR 800(6400)
2.5 = 1.25 or 4:5..FSB 333 = RAM-416 = DDR 832(66/6700)
3.0 = 1.5 or 2:3 ...FSB 333 = RAM-500 = DDR 1000(8000)
3.2 = 1.6 or 5:8....FSB 333 = RAM-533 = DDR 1066(8500)
4.0 = 2.0 or 1:2....FSB 333 = RAM-667 = DDR 1333(10600)

Have fun.
