AMD 1090T BE Overclocking past 4.1ghz

post #1 of 36
Thread Starter 
I've been tweaking my 1090T and have reached 4.1ghz (after 1 hr of prime95). This is at 1.488 Vcore. However, I'm not able to get above 4.1 by simply adjusting the core multiplier. I've been raising the VCore, but that doesnt seem to help (all other settings are at stock settings except turning off CoolNQuiet, Turbo Mode).

Should I continue to push the VCore past 1.55V which is recommended by AMD? My temps are pretty good (custom watercooling); the cores are all between 37-41C, the CPU overall around 57C under prime95 load. The reason I ask is because the article here says that for BE CPUs I should just have to adjust the core multiplier and VCore to get the highest CPU frequency. Is this correct or should I still have to monkey with the NB voltage and NB frequency?

Another question - when monitoring CPU temps when overclocking this chip should I only care about the core temps, or should I also pay attention to the CPU temp overall?

I'm using this RAM (G. Skill DDR3 2133):

Thanks in advance.

im at 4.3 at 1.55 only if you had adequate cooling for it and remain under 50c

50C on your cores or 50C on the socket?
post #4 of 36
You want to look at the socket. 57 at full load, you should stop there.

Since it's a Black Edition and I can change the multiplier should I be changing the NB speed / voltage or RAM speed / voltage?

You want to look at the cores, not the socket.

Thanks for the replies guys! Can anyone answer whether or not overclocking a BE CPU should involve more than just tweaking the multiplier and Vcore? Specifically when overclocking above 4.1ghz.
post #8 of 36
Well, my 1090T loves the multiplier. I really don't bother with much else. Although, you may need to use the FSB just a little when you get up to 4.0GHz to get better stability.

i've been playing with my "1090T wannabe" and in order to go past 4 i have to make adjustments to the cpu/nb voltage. for example, if my vcore is at 1.4 i'll set the cpu/nb to 1.35 or 1.36. i try to keep them within o.05 v.

i read here that raising the blck (fsb) may help in the overall performance of the system. so, you can play around the multiplier and the fsb keeping the 4, 4.1, 4.2, etc as the reference. note that adjusting the fsb will adjust the speed of your rams. but you have a lot of room given the speed of your rams. you may have to increase voltage on your drams as well. mine is set at 1.63v.

a better guide is written by El Gappo here in ocn. i wish i can link it but i am away from my desktop atm.

gl and watch those temps closely!

Thanks for the reply. I'll try and up the cpu/nb voltage in my next round of testing. I'm also adding a 576 Qc Watt peltier chiller in my system tonight to get the temps down even further (right now the cores are at 33C after 5hrs of prime95).
