with case side open
id recommend an xspc raystorm kit if youre up for it and wishing to overclock like mad.
theres a thread of a couple noobs trying it out and well we was amazed lol
H100 or similarly performing AIO's like the collermaster seidon, NZXT Kraken. Or one of the top end tower coolers, like the Phanteks PH14, Thermalright and noctua offerings.
I managed to safely cool a 8350 at 1.475v full loaded. That netted me an OC of 4.8, but all chips will be different, so just use the voltage as a baseline.
NB freq is at default 2200 Mhz and Ram is at 1333. Ram is Kingston HyperX blue 1333, going to try 1600. What is the best timings for Ram for FX?
NB freq - don't know how far my board will allow, but what freq will give better performance, I will try it out.
I am happy @ 4 Ghz on the CPU with low volts, so won't go higher than that as it sucks more watts if I increase freq and volts. If I increase the NB freq do I still need to increase the CPU volts or try the CPU NB volts?
Sorry new to FX and need some help in getting the best out of it.
If you can get cas 6 out of 1333mhz, try that.
Just increase the CPU NB volts for the NB. It's separate from CPU voltage.
for NB speed just try to go as high as possible, probably 2500-2700. I don't think there is a specific speed for best performance.
Mine just decided to no longer run higher than 2500 today, I've had it almost 2800 before and now it'll only do 2500 stable
@irony, have you ever applied 1.6v to ya chip?
and does it lock up when at 1.6v and above? PLL lowest setting!
This is what I have
Kingston HyperX Blu 8GB (2 x 4GB) 240-Pin DDR3 SDR...
running @ CAS 6 will be a dream.
I thought running at 1600 will give higher bandwidth?
And I have 4 of those sticks for 16GB total (is 4 x sticks still ok for OCing?).
Just push them up like any other ram. I doubt they wont do 1800mhz.
Anybody else here with the same board as me
havent seen anyone with an evo for a while.
i usually look back through pages to see system specs of people on here.
I have that board as well as an M5A99X Evo
damn nortons got a bunch of evo's lol
any crunching/folding comps coming up i can prepare for?
You just missed a crunching one- 7/5 thru 7/8... ends in about 2 hrs
You can join up anytime but if you want to wait on a competition in order to join then you need to keep a watch out on our WCG threads
Ya I've been up to 1.65 trying to get 5ghz+ stable. It doesn't lock up from the high voltage i don't think. It's been a few months since I've tried it, don't remember any details. It would boot even with lower volts at 5.0-5.2 but can't get it stable for anything in any sort of stress. Might give it another go, now you got me wondering lol. Time to turn the A/C up and get the ambient down, lolz It's over 100 outside right now...
Edit, maybe this is a noobish question, but what is PLL?
i got a m5a99x evo r2.0
im not too sure, read a few things today.
what i know is phase locked loop, means the internal clocks have more volts to draw upon, and is better for higher FSB's.
on our boards its called CPU VDDA.
tbh i havent seen any impact on overclocking/stability.
well my chip locks up when 1.6v or more is applied. i cant get pass 4.9 stable, im trying different things but its a lengthy process and the heat doesnt help! and it wants plenty of volts!
I cant get 4.8 stable on mine, i gave up and left it at 4.5ghz on 1.4V so just above 0.2 core V
Oh ok. Well I have my FSB at 250 so maybe that will be of some help. I normally just disable most everything including that, cuz I didn't really know for sure what it was.
How hot have you gotten your CPU with that loop? My max stable clock so far has been 4.875, and it gets to around 50c pretty quick with IBT.
I got some new memory, it's Kingston hyper x 2666, and then suddenly I couldn't get my NB to OC high enough to use it at that speed. Apparently it has to be faster than memory speed? I never had any memory faster than 1600 so it never came up. So It's at 2400.
@pipson: 4.5 is the sweet spot on mine too. It's perfectly stable there with 1.33v
run ram at intended speeds
Deneb and Thuban benefits most from NB overclocking, push it around 2.7-2.8ghz. Beyond that the performance increase will be less significant in relation to the voltage needed to make it stable.
I was talking about FX-8320 OCing.
lol what am I thinking , anyhow, you should be able to push it up 2.6ghz on stock volts. Piledriver and Bulldozer is not as beneficial to nb overclocking as the previous gen. Though you might see a difference mostly in benchmarks from stock to around 2.6-2.8ghz. They are sensitive to nb changes though and may require higher voltage above 2.6 based on my experience.
It has two XMP profiles, 2400 and 2666, I'm running it at 2400.
FX 8320 @ 4.8 Ghz with 1.42v, Stable so far.
