First attempts at OC: 1090T @ 4.1

post #1 of 15
Thread Starter 
Motherboard: ASUS Sabertooth 990FX
CPU: 1090T
RAM: GSkill Sniper Series @ 1600 ; 16 GB (4x4GB)
Cooler: H50 in Push/Pull.

Idling @ 22C at 21.5 multiplier (4113 MHz) vCore @ 1.475V (goes up to 1.5V at load) with HT Link @ 2600 and CPUNB @ 2800

Full load max temps between 42 and 46C

RAM timings changed to 8-8-8-24 from 9-9-9-28.

Passes wPrime 1024M with flying colors, but inevitably a few minutes into a Prime95 Blend I get a "FATAL ERROR" for rounding on single cores at a time (not really sure what this signifies). Seems to always be core #4 first, then core #3 shortly thereafter. Computer does not crash, just shuts off those cores for the Prime test.

I feel like I should be able to go higher than 4.1 since I'm not really at the heat wall yet, but going up to 4.2 crashes, and I'm not really sure if I should go higher than 1.475V for stability. Any suggestions?

Put the ht back to stock and try mix of multi and FSb for oc and you might be able get lower voltage.
Your temps seem fine but you are close to your voltage limit.
post #3 of 15
Your voltage seems too low... It took me 1.52V under load to keep it steady at 4.1. This is with the fsb set to normal (200), NB @ 2600 (1.25V) and HT at 2600. Use HW-Monitor to view your temps and voltages all in one place along with the min and max values.

I'll try boosting the CPU voltage a bit, and my NB, I think its only at 1.15 or 1.2.

How do people hit 5.0+ with the voltage seeming to cap so low? Are they just hitting it, but its not stable? I was hoping to hit at least 4.2-4.3 stable, and with the heat where I'm at, I feel like it should be able to do it, though with the voltage already at ~1.5 I thought that was the highest you really wanted to go.

Failing Prime in 2 minutes means you're highly unstable.

You DEFINITELY need more volts. Id say always leave the HT link as close to 2000 as possible. Reset your NB also to stock values.

Overclock only your CPU ONLY. Like someone said -- I'd be surprised if you don't require at LEAST 1.500v, if not 1.525v to be stable at 4.1ghz. Once you KNOW your CPU overclock is stable, you can move on to clocking the NB (reset your CPU clock to STOCK til your NB is stable)

Once your NB is stable, you can move on to the RAM (With both your CPU and NB at stock). Once all of the things are stable by themselves, you can go ahead and set them ALL to their "stable values" and test everything altogether.

You could also be hitting your cpu's limit. I know some 1090ts overclock better then some how ever personally with mine I couldn't get mine passed 4.0Ghz. And even at 4.0 I had to run something like 1.525Vcore and it ran way high.

See, I had been under the impression that when you start to wall on the CPU, sometimes a boost to HT/NB would halt the bottleneck and stabilize the OC.

Perhaps I was mistaken. I'll try your method tonight. I just tried it again at 1.52 and 1.54 and cannot get it to stabilize so perhaps I should just trot back down to 4.0 and be happy.

4.0 is probably your best bet. I tried hitting 4.0+ on mine when I had it and just couldn't find the nudge to accomplish it. I upped my vcore, nbvoltage, nb frequency, ht frequency, adjusted my ram voltage. I tried everything I was told and I just couldn't get passed 4.0. I also had it cooled by a corsair h60 and even with that my temps were pretty high. I think I was reaching something like 70C on the cpu socket area and 65Cish on each cores. Not good from what I have been told. If your looking for a better overclock your best bet would to perhaps snag a BD. I hear those things overclock nicely.

Highest mine went was 52 at 1.54 and still errored out in Prime95.

I had it stable at 4.0 and only about 1.425V , but wanted to go higher since it was only hitting about 42-44C (load) at that speed. Felt that having another 13 or so C to work with would be able to produce a much higher result, especially considering that it was hitting about 40C (load) at stock clocks. Stock clocks it idles between 16-18C. LOVE my H50!

Yah stock clocks they run pretty cool tbh. Mine would stay in the upper teens on the h60. But when i clocked it to 4.0 it was getting hotter and hotter. Close to the threshold or w.e. of 55c and 65C sometimes going passed that. I remember some where someone telling me the highest you want amd cores to go is like 65 or 55C and the cpu socket area 55 or 65C i cant remember which was for what. Either way I wasn't liking the temps nor the vcore I had to use for 4.0. I think the max vcore for anything is like 1.55 and at load my Vcore on the 1090t was reaching 1.55ish.
