780i and a Q6600?

post #1 of 13
Thread Starter 
How good are the 780i's/790i's for overclocking quad cores
Anyone run into issues? I know the 680's had huge issues.
Thanks.

i have not had any major issues. My ram crapped out on me, but that was no fault of the board or the processor. Search Robilar, he has an excellent OC guide.

The 680i is pretty good for OC'ing quads (IF you have the right versions). The max FSB you'll get is around 480-490 due to motherboard straps. With the Q6600, that equates to over 4GHz, so the motherboard itself isn't really the limiting factor. BUT keep in mind the "A1/T1" version of the 680i has the proper GTL reference voltage fixes, the older versions (such as the AR/TR) and "LT" versions do not have this fix.

The 780i/790i are even better, as there are individual, adjustable GTL reference voltage lanes which make quad core OC'ing even better.

I've been out of the chipset game since the P35's, so I was debating an X48 vs an 780/90i for a build. So, I could achieve 3.4 ghz stable, daily use with a TRUE/Tuniq, off the 780i build, correct?

While I obviously won't guarantee anything, getting to 3.4GHz on my Q6600 even with my 680i A1 was relatively easy. It shouldn't be a problem with a 780i/790i.
