Want to OC just my CPU - Page 11

One of the issues with ran and the voltage increase is heat... these XMS have some pretty sweet heatsinks on them, so you should be fine with up to around 2.2-2.3 vdimm.
Can the 2gb kit use the same voltage as the 4gb kit though?

On the corsair website they listed as having the same voltage and timings. Its interesting, both the 2 & 4 gig 4-4-4-12 kits were tested from corsair at 2.1v, while the 5-5-5-18 kits were tested at 1.8v, and in one of corsair's OC tests (they tested the DHX heatsink) they ran their own ram at 2.4v w the tight timings of 3-4-3-9. I think that it should be fine.

Sweet, so I can oc to 3.3 and tighten my timings to 4-4-4-12 at 2.2 or 2.3v?

And I do love the heatsinks on this ram, but one thing I hate is that they really limit the cpu cooler I can use with the board I have. They sit right next to the cpu. Oh well, I have a Thermaltake V1 that keeps me at about 47-48c oc'd to 3.2 at load.

And thanks for the help guys!

Yea, you should be able to hit 3.3GHz now, if that was really what was holding you back. Try running memtest to see if the ram is stable (what speed is it running at?) And yes, the ram is awesome, i've had a hard time finding a heatsink too, mostly because there are never any measurements from the manufacturers about how high from the mobo the fins start. For right now I've lapped my stock heatsink (weird but true) and added an old 92mm fan to it.... load temps are down 7c, so I cant complain.

Well, it is running at basically 400, so 800 (i think like 414, so 828) with a 3.2ghz oc. It was a bit underclocked when I started.

Then you've got alot more headroom (as far as ram goes) for more FSB, try keeping the multi where it is, and see how high you can push the FSB. The ram shouldn't be a holdup for a while.

So I can't seem to get a stable 3.3ghz overclock. I didn't oc my ram at all, and upped my voltage to 1.45 (shows 1.5 in cpuz). I don't know what it could be. My ram has just a slight overclock at 414 (828) but prime95 wont go more than 10 minutes without erroring out.

What voltage is your ram running?

It was at 1.8, but I turned it up to 2.0. It seems to me though that since it was running fine at 1.8, such a minimal oc on it shouldn't make it unstable all the way to 2.0, should it?

It depends on the timings probably. What timings are you running at? As mentioned before, you should try memtest to ensure that your ram is good. It does the test before the OS opens to help eliminate variables.
