Overclock FX6300: suggestions and ram problems

post #1 of 43
Thread Starter 
Hi everybody.
I've just bought my new platform based on FX6300, Asus M5A99FX Pro R2 (with latest bios), Noctua U14S, Corsair 2x4Gb 1600MHz Cl9.
I use my pc about 18 hours a day, working with lots of different programms (MpLab, Eagle, Codebloks, Povray, Matlab, LtSpice) and always running folding@home cpu.
I haven't cooling problems (47°C on CPU and 33°C on Cores after 6 our of Folding@Home 6 thread full stress with stock frequences).
Now I'd like to overclock the system without lose stability, it is a must.
I've done some tests and the cpu passed 1 house of OCCT Linpack (6Gb of memory) without errors at 4.5GHz with 1.41V and at 4.6GHz with 1.44V. What about? Is it good? Is still useful going over?

Talking about ram, I have some problems. At 4.5GHz ram is not stable with default frequences/cas/voltage. How is it possible? I can pass 1 house of OCCT Linpack or 6 hours of Prime95 smal FFT but I can't pass 10 minutes of Prime95 Blend without error (with the ram at default setting).
Now I'm running stock setting on CPU, NB and Ram and I can pass lots of hours without errors in Blend (ram 1600MHz, cl 9 9 9 24, 1.55V) but with default settings I have the NB at 2000MHz and the HT Link at 2000MHz too.
When I try to overclock the cpu what frequences have I to choose for NB and HT link?
Why the ram is not stable running default setting with the cpu overclocked?

Thanks in advance

hello,
your cpu-nb and ht can go up to 2200mhz and cpu-nb on mine uses 1.225v to be stable.
oh yer, monitor your ram tab on cpu-z, I found after high oc the ram if on auto change to different timings, 2133 timing.

you could try putting your ram in 1866 ram timings, 9.9.9.27.47.2T.

Right. When the Ram is overclocked do not use AUTO timings, use MANUAL timings. For 1866Mhz you may need 10-10-10 as you stock is 1600Mhz at 9-9-9. Increasing Ram voltage also helps.

Ok thanks. I'll try with lower CAS.

Wich is a maximum safety dram voltage for a daily use?

I would say 1.75v.

Is it safe for the dram controller?
However, setting NB and HT to 2000MHz, are there any performance problems?
post #8 of 43
For FX series no. The HT Link is okay around 2400Mhz but the cpu nb is best left between 2000-2200Mhz. The Ram can take upto 1.75v. I have ran my Corsair value select Ram 1333Mhz at 1800Mhz at 1.75v with my Athlon II x2 250 and it's still fine.

Ok, thanks for the feedback smile.gif

For a daily use, which is a good frequence for the FX6300 in order to have good performance without too much power consumption and without decreasing the cpu lifetime?
post #10 of 43
hello again,
1.65v for your ram, 1.75v is to high. don't auto voltage your cpu-nb. I found mine liked to give 1.45v for the cpu-nb at 2400mhz , which is wrong, 2500mhz is reachable with 1.275v.
