Overclocking the FX8350 questions

[Thick8]

Hi Guys,

I've been overclocking for many years now. I havn't done a major upgrade for about 4 years so I'm kinda out of the loop.
This Asus BIOS is impressive but I'm a little lost. So far I've just done a basic OC with a multiplier and voltage bump. I also hacked a H50 and H100 loop to be able to keep things cool at 4.8Ghz and 1.4375v. I made it up to 5.1Ghz at 1.5v but the temps started getting out of control.
Now I've ordered a water cooling setup (will be here Monday).
Apogee Drive II
Mini res
120mmx240mmx60mm all copper radiator
4 120mm pure wing fans.
Can anyone who is getting 5Ghz+ from their 8350 post their Sabertooth BIOS settings so i have a jumping off point?
Thanks.
John

I think it will be more possible with your Water Unit, I just picked one up as well for cheap at Tiger Direct a few weeks ago. I just got my Hyper 212 EVO installed on it with a Silverstone FHP-141. I will have results soon on this chip, I am not getting anywhere near 5GHz but for the price, I simply do not think you can match it with anything else on the market.

Update 1: Now Priming Stable at 4.5Ghz on 1.42v core.
Update 2: Now Priming Stable @ 4.6 on 1.5v core.

Wow if you've got an 8350 that'll do 5.1 on 1.5v then count yourself lucky. What are you using for stability test?

The key with FX chips overclocked is keeping the vrms cool. Make sure a fan is blowing on them. ..memory fan coolers work best because they clip on.

Good luck

It looks like I am about tapped out at 4.6 on Air as well. The addition of another Silverstone 141 to the HS as a Pull Fan got me to 4.6

Edit: Is 56c Load after 8hrs of Prime a decent Temp for this? Also, would Liquid Metal TP take me down in some temps if I got it?

56c seems about right

ive always wanted to delid my FX chip like in the old chips, but i think they weld them on now?

Be thankful AMD is using solder. If we had to delid our chips like some Intel users have been I think our members on the AMD overclocking side would be substantially scarcer. Now Intel says they are using TIM because it is cheaper than the solder they used to use... I'm not sure if the price different for Intel would actually reflect in an end user's price or is only a figure on some accountant's spreadsheet. I just know AMD needs all the help it can get keeping hobby overclockers buying their chips.

I did lap my heatsink. definitly helped have a solid surface area contact.

Ill look at my bois tonight and give you some suggestions its been awhile though....play with the cpu-nb volts a little

Temps are good, 4.6 is probably about as high as you're going to go on air.

Oops, I forgot I started this thread.
So I ended up at 5.014Ghz stable at 1.488v. I set the FSB to 238 but it's running at 238.8. temps stays under 60c running Prime95 on all 8 core. The Asus BIOS has tons of options to stablize voltages and condition the current to make for a killer overclock. Needless to say I'm happy with the results.

show some results here

[Thick8]

Here's a couple of screens of the BIOS settings and a Cinebench run. I'll do a Prime run this evening. I thought i was running 1.488 volts on the CPU but forgot that I raised it to 1.49375

nice
