Hey evryone, new to overclocking but ive done a little research. I have a 1090t on air cooling set at 20 multiplier and fsb at 204. Vcore @ 1.42v and ram at 9-9-9-27 @ 1.59v. My computer tends to crash crysis after about 15 to 20 min of play and intel burn in test says the overclock is unstable. Temps are fine on the cpu. I really want to get the cpu to 4.1GHz but i have not touched the northbridge settings which ma be what i need to do, any tips would be appreciated.
Did you checked cpu temp after 10-15 minutes of playing? It could be an overheating...
Also, try reducing the multiplier or FSB until you get 3.5GHz and play again, see whether your system is crash or not...
Yea I got it figured I had a bad overclock on my vid card. Now burn in test will pass the overclock sometimes and sometimes it fails it. Everything plays fine right now at 201 FSB. I just wanted to see if Icould squeeze some more out of it. I got 1333mhz corsair which should be ok to raise the fsb more than 204 but I have it at 201 now and all is stable, I just want to see if theres anything else I can do to improve stability and OC to 4.1.
Drop the memory ratio to 533 from 667. Bump the NB/IMC volts to 1.2v. Disable Turbo. Lock the PCIe to 100MHz. Drop the HT multi to '8' (or drop the speed setting to 1600)
Settings on Auto tend to over-volt <--- keep an eye on this (and monitor for the Thuban Volt Boogie).
With the above settings you should be able to get 16x250MHz stable -- just depends upon the voltages and temps, otherwise. I would consider 1.4v the sweet spot for the x6 -- be careful above that.
16x250MHz will raise the IMC/NB to 2500MHz. Your RAMs will be at spec 1333 (5.33x250). Lotsa tinker room with the cpu multi from there. As tempting as it may be, don't run 1.45v+ for the long run. It will do 1.5v+ but do you really want to go there in the Big Picture?
