Is there anything else I can OC???

post #1 of 5
Thread Starter 
I finaly OC'ed my CPU (3.8Ghz) and hit a wall because of my RAM, NB is also maxed out at 2800Mhz, I also OC'd my video card GPU\\memory, also maxed out.

I noticed a few other things in the BIOS that could potentialy be OC'ed, such has the HT link and the PCI-e.... but I read online that these should not be OC'ed becuase of risk of system damaged.

Is there anything else I can fidle arround in order to get more out of this baby?

I would play with the RAM timings but I doubt my system will remain stable......

RAM, CPU, NB and the GPU is all there is to (should) be overclocked.

Yes, you can OC the PCI-E bus, but it does nothing for performance gains. In previous Core 2 mobos, the PCI-E could be OC'd to achieve stability at higher OCs, but it was almost never worth it to change it.

And yes, there is a risk of system damage if you push the PCI-E too high.

I would leave it alone.

keep your ht close to stock +/- 100mhz
there is no gain from overclocking it, and you could lose stability

nb is fine to oc, great gains can be seen there

lowering ram timings can yeild more preformance boost
going from cl9 to 7 is a pretty big improvement if the ram can do it

I don't think I can lowing the RAM timings, my system won't make it up to 3.9Ghz without it being unstable in Prime95 (Blend). I suspect this is because of the RAM, since I was able to OC the heck out of the NB and the CPU without any issues.

I can OC the CPU up to 4.2 and run Prime95 without errors, so long as I run the (Small FFTs) test (CPU only) instead of the (Blend). As soon as I try(blend) it reports memory rounding errors in the result.txt in the Prime95 folder.

I didn't OC my RAM, its still at the stock 1600Mhz speed.....

I know this probably wont' make sence, but I read a few posts where OC'ing the NB actualy stabilized peoples OC... I'm wondering if OC'ing the RAM might do the same? or maybe I should bring it down to 1333Mhz? and bring up my CPU OC higher?

As far as RAM frequency, 1600MHz is often called the "sweet spot" for AMD chips. Your 1090t (with good RAM) should be able to hit about 2700Mhz-3000Mhz NB with RAM at 1600Mhz CL6-CL9.

As a general rule of thumb CPU frequency>NB Frequency>Ram Timings>Ram Frequency

Edit: Oh, and for me, upping the NB frequency did stabilize my overclock.
