post #6151 of 8112
Did u guys tried to lap the fx 8120 , i have bought in february a thermalright true spirit 140 which has a wery unflat base that needs to be lapped and i was wondering if the cpu shoud be lapped to or if its safe to lapp it
post #6152 of 8112
you can lap the cpu. Most people don't as it voids the warranty.


Then again if you overclock so does that. I lapped my antec 920, but not the cpu itself. I took a machinist flat edge and found it to be rather flat already.

FX4170
Asus M5A99x
cooler master 600w
3D HD6850
CPU Cooler Thermalright 140 True Spirit with single fan
CPU overclocked base to 4530 Mhz and turbo boost to 4830 Mhz on 1.413v
FSB 2317 Mhz
Ram 1680Mhz on 1.65v (8gig)
NB 2317 Mhz
LLC on NB set to medium (50%)
LLC on CPU set to Optimised
CPU core temps do not go over 40c
CPU socket Does not go over 50c
MB stays around 38c
VRM spread is on
Everything else in the Cool n Quite section is on. TPU and EPU is on
Game FPS increased a few frames with this overclock from the standard over clock I had from 4600mhz with turbo off. System boost faster and loads programmes and games faster with this overclock.
(Interresting)

Can you please replay to me when you got time, go to the BIOS, and see if is possible to change CPU memory controller mode in Ganged mode (like on PII CPU's). Thank you in advance.

I did some test,a nd i found that FX CPU's don't suffer from same bug as PII CPU's using unganged mode, but, my testing is very limited (only few games), but anyways, i would like to try it,a nd mine BIOS (Mainboard) do not allows me to turn off DCT Unganged mode, or in translation, to turn on Ganged mode.

Thanks.

What should I expect my limit to be on a FX-8150 with a Hyper 212 Evo. Right now I have 4.4GHz at 1.4125v. My max temp is 54C after an hour of Prime95. The temps get too high if I raise the voltage anymore and the clocks are unstable above 4.4. I have only changed the multiplier, would it helped if I raise the FSB, downclock my memory multiplier and possibly raise NB?

that good for air cooling

Okay, I was hoping to get 4.6 but 4.4 is good. Are there added benefits to raising the NB past 2200MHz (thats where Im at now).

Also I read about claims of the chip being better for gaming if your BIOS has the option to run one compute unit per core. In my BIOS I have this. The guy was taking too long to post his results biggrin.gif so I got skeptical and tried it myself. My scores on Unigine Heaven 3.0 and 3Dmark11 were basically identical. And when I ran Cinebench, even when I overclocked to 4.9GHz (I was able to get overclocks much higher using the chip 4c/4t because of less heat) my score still fell short of my old Phenom II 980BE. So I guess this guy was full of it, or I was doing something wrong. Anyone heard of these claims or have any input?

my 8150 is definitely slower than my 1090t

I ran the 8120 for a while and didn't like it at all. Maybe I had a bad chip, but would NOT OC for anything. I ended up selling it and went back to my FX-4100 - and I overclock the heck out of it. I had it over 4GHz on air, but it's underwater now and easily clocks over 5GHz. I keep it at 4.9GHz for long gaming sessions. Never had a problem with the 5GHz clock, but I want my chip to last a while...I'm kinda fond of it. wubsmiley.gif
Warning: Spoiler! (Click to show)

thumb.gif GREAT Chip!

here give this a read it shows it all and bench tests at diffrent NB frequancys and HT link frequancys and diffrent ram speeds
