1055t overclock advice

post #1 of 14
Thread Starter 
hi guys!
as the title suggests i would like a little advice on this CPU.
i dont have any trouble clocking this cpu to 3.8ghz, and thats what i run it at. and ive even clocked it at 4.4ghz all done through the bios. problem is anything over 4ghz doesnt actually seem to take effect...i ran ASrock extreme tuner to verify the clock is in effect and also CPU-Z both say that im still at 4ghz.....that seems to be as high as it goes no matter what i do with the settings in bios. any ideas as to why it wont register anything higher?

here is are the settings i used to achieve 4.4 from what i remember
bus speed - 271
CPU voltage - 1.525v
multiplier - 16.5 (4415mhz)
HT link as close to 2000 as i could
NB voltage was around 1.3v
ram - 1444mhz
ram volts - 1.650v


anyway heres the rig

AMD 1055T
ASRock 990fx extreme 3
8gig DDR3 1600Mhz XMS3 Corsair
Gainward GTX470
Viper 80+ 850w PSU
120Gb Mushkin Chronos SSD
1Tb 7200 Hdd
Vendetta 2 cooler

I wonder if there is a distinction between the base multiplier, (14X) and the turbo sped multipliers (up to 16.5X) that is causing the discrepancy. Ensure that turbo and any proprietary turbo enhancing functions on the board haven been disabled.

Yeah, give that a try.

Also, I would suggest just running it at 4.0Ghz and try get your CPU/NB (CPU/NB and NB are completely different btw) as high as possible for the best performance, 2600-3000Mhz with a max voltage of 1.3/1.32 for safety on the cpu/nb. 1.52 volts will cause degradation over time. 1.4-1.46Ghz is what I'd deem a good 24/7 voltage to run.

thanks for the replies! all turbo and cooling options are all disabled in bios. this is what i have so far now....
13b1.jpg


and im not sure what im doing with the RAM timings, ive read articles on it and it doesnt make much sense to me lol. i dont know what they mean if someone says i need to tighten my timings, does that mean i go from 9-9-9-24 to something like 8-8-8-20?

hre6.jpg


like i say anything over 4ghz doesnt seem to take effect :S bloody confusing. temps are no problem either, im getting 50 under load.

Your HT link needs to be at 2000Mhz or as close as possibly possible as anything over 2000Mhz starts to give you less performance. Thubans benefit greatly from a good overclock (4.0Ghz is the sweet spot) with a good CPU/NB overclock. Aim for 2600Mhz on the CPU/NB and see how you go. Truth be told I wouldn't be too bothered about not getting over 4.0Ghz as the performance gain is very low compared to the 4.0Ghz CPU and 2.6Ghz or higher CPU/NB.

As for your RAM, yes, tightening one's RAM timings means lowering the values. You can try lowering it one set of timings, such as 9-9-9-24 to 8-8-8-20. Testing with games and stress tests like Prime95 for a few hours will give you an idea of how stable you are or not (crash, freezes, blue screens or not, etc).

For the time being I would focus on your CPU overclock stability and trying to run it with as low as voltage as possible without it crashing. Then I recommend moving onto your CPU/NB as that will net you quite a bit of performance in every scenario, and then when you're ready and know that your CPU/NB is stable and is running at the lowest voltage possible that gives rock solid stability at whatever you speed you can, move onto RAM timings. Off the top of my head I can't remember what benefited Thubans (1055T, etc) more.. RAM speed or tighter timings. I'll look it up now.

Best of luck thumb.gif

EDIT: Turns out you want to overclock your RAM speed instead of timings for Thuban as the bandwidth really opens up once you have your CPU/NB at 2400Mhz and above with your RAM at 1600Mhz.

EDITT: I wish my 1055T hadn't died :/ such a great chip.

You screenshot clearly shows (X14)X16.5 as the CPU multipliers, which suggests to me that it is still treating the upper multiplier as a "turbo" frequency rather than a base frequency.

Check if a setting along the lines of APM is disabled. According to what I have read it is a power limit function. If you can't find it then don't worry. Have you updated your bios? Latest?

yup, everything that needs to be off is off. bios is latest version too.
