how much shall i push it in terms of heat? I increased the vcore 1.416 now as it failed in test. Is it safe under 60 celc for my cpu im getting 51 celc core now with this vcore.

Safe temps are under 62 Celsius on the Core and around 72 Celsius on the socket. So you have lots of room to work with.

The thing is my cpu core temperature is very near to cpu temp which are 47 celc and 48 celc respectively (under load prime blend test). Sometimes it even passes the cpu temp.

Is it normal or is something wrong? Using Hwmonitor to check temps btw

thks

I use core temp to monitor temps and hw monitor, then if theres a major difference i know somethings not reading right

Le me stress testing:





not a minute passed after uploading this image and two of my cores crashed
i guess i need help figuring out what im doing wrong voltage wise.
also can you please tell me if you think my temp's are acceptable or am i right on the limit, for this was a very short test and it jumped up pretty quickly.
(check out rig for more details)

Thanks in advance and please tell me if you need more details on bios settings etc'.

Thank you so much for this guide. I have worked with other guides and along with my past experience and with all the work I've done over and over again I have never been so successful with my cpu oc. I had only been able to get my fx-8120 to 4200MHz and that was way too hot. So I had to drop it down to 4100MHz. Your guide, with just a few difference in settings than what I have done, has got me to 4400MHz. Huge accomplishment. I have stuck with multiplier ocing with the bulldozer for the most part but on my AMD's in the past I always did a little of the multiplier and fsb combination. I still would like to stick with multiplier ocing. I so want to make it to 4.5GHz but my 7th core keeps crashing.

the most interesting difference in my success is my temps. My sockets temp has always been at least 12*C higher than my cores. while my cores maxed at 61*C my socket would reach 73*C and higher at 4.2 GHz . I have always heard that a way to solve this is adding a fan blowing on the back side of the cpu but wouldn't find one thinking it had to be a certain size that I couldn't find locally. You mentioned the solution of using the fan from the cpu heatsink. It was just that easy to get a perfect fit. I have it attached to my right side case blowing right on the cpu and my socket temps have dropped below my cores by 4 to 6*C at full load. The cores are hotter than the socket again! Cores would reach 61*C while at full load with my socket at 55*C. I now have 17 degrees from the 72*C max on my socket that you suggested I should leave.. I have another cpu f&hs. If I can fit it under the H80 fans and radiator and force that air on my vrms will this give me anymore stability to make another 100MHz to a 4.5GHz? If I could get my FX-8120 to 4.5 GHz I promised myself I wouldn't work any further to get higher. I would probably work more on stability and drop some voltage if I got to that goal.

Also could you give me more details about this setting you mentioned in op:

"NB 1.8V Voltage - Adjust the voltage for the Chipset/CPU Multiplier. Higher multi requires more voltage"

How many increments and what would be that max voltage for that? I would like to see if this could get me to 4.5 GHz too. Again thanks for the help to get this far and you can bet I will vote yes to your poll.

Nice Overclock Dorian101. It looks like you will be at the limit of your CPU cooler with 4.8Ghz.
You should start by increasing the cpu voltage a few notches and then re-trying. Between 4.8-5.0Ghz is where most of the FX 8350's start to require a lot more voltage to keep stable.

You can also try increasing the CPU/NB voltage a couple notches as well.

Hi aas88keyz,

it's amazing how much that fan drops the socket temps, glad it worked well for you. I would recommend putting a fan over the VRM's as well, because the cooler you can keep them, the more effecient they are. It may not make as large of a difference on the CHV board because it has such a nice heatsink, but if you have a fan, why not.

For an 8 Core FX, it's very unusual to have the Socket Temp lower than the Core Temp, even with cooling on the socket and the VRM's. This leads me to suspect that maybe your H80 isn't seated properly on the CPU, or the airflow through the radiator is not working well. By addressing that possible issue, you should be able to reach 4.5-4.6Ghz with your Overclock.

About NB 1.8v - This is more for using Liquid Nitrogen to reach extreme Overclocks. For air or water you should leave it at 1.8v.

Sorry took so long to get back to you but I have been creating headaches for myself. I don't remember all the details but I did as suggested and reseated my waterblock... 3 times! LOL. Anyway, when I took off the water block of the H80 I did notice that the TIM wasn't spread evenly. Probably cause it was so thick and I might have been in a hurry and just dabbed a little in the center like in the olden days. The system must have been running half way decent though cause it didn't overheat that bad in the few months after I seated it the last time. 1st time I tried to reseat yesterday the temps were much higher and not capable of a stable 4.4 GHz I had before then. When I removed it I could see where all the bubbles were. 2nd time was with a rubber glove i tried to smooth it over with lightly. kept sticking to my glove though and I think I had too thin a layer. As soon as I stressed it took seconds to overheat and crash Prime. 3rd time, before I went to bed I tried two thin lines of TIM, seated the heatsink and glided once forward and back and again left and right. I haven't stressed it yet but idle temps are a lot better. for core and socket. I did place another fan on the vrms below my radiator. can't tell if it helps or not. Not that I could see the temps on it but on my Crosshair the heatsinks on the vrms don't usually get hot to the touch for me but doesn't hurt. I do think that it makes it a little more stable but I might be wishful thinking. I will let you know what my stress tests come up with with my newest reseat of the waterblock.

Hopefully it turns out well. I set up my FX 8150 to give you an idea of what to expect. (Most 8120's can Overclock the same as 8150's)





Here's a 5 minute run of Prime with this above cooler. It's nothing fancy. You'll have to look at the Maximum Temps because Prime was already ended before the screenshot was taken.

Couple Things About the H80 Warning: Spoiler! (Click to show)
Pea Size amount of Thermal Paste right in the center of the CPU works well to get even coverage. Let the pressure of the H80 waterblock spread the thermal paste to prevent air pockets.

Tightening the H80 Block too much can cause high temps and poor performance.

H100.jpg

The Water Block should be tightned evenly or you'll end up with the above issue.

Make sure the Rad Fans are plugged into the headers of the Water Block, then the speed can be controlled by the button on the water block.

Radiator Fan Placement
Intake - Fans are set up push/pull drawing air into the case. Other case fans should be set up to blow air out of the case to create a negative pressure, to improve CPU cooling.
Exhaust - Fans are set up push/pull drawing air out of the case. Other case fans should be set up to draw air into the case to create a positive pressure, to improve CPU cooling.

Hope that's helpful.

I lost most all stability along with higher core temps. This 3rd time reseating the cpu I finally dropped the temps of core and socket where they used to be. Except then I was at 4.4 GHz and no higher than 55*C on either socket or core. Now I am forcing a 4.3GHz oc and barely getting my cores in at 61*C and socket 55*C. I don't know if I am failing miserably with the TIM or what but I was doing a lot better when I was following your guide in the beginning and then I started messing with things trying to get to a golden overclock (to me atleast) of 4.5GHz. I don't know how much of my TIM I have left and yes I know it only takes the smallest amount but I was just not getting it to spread evenly. I don't know if I should try a reseat again and see how it was spread or accept what I have now. With the temps that I have now do I have the chance to get considerably cooler with reseating once or twice more? I never had this trouble before but I think the difference is the consistency with the TIM. I had more liquidly TIM in the past and now the stuff I have is real thick. though it had a good review. What do you think?

It may just be a TIM issue then. If it's really thick it must not be spreading well when you put the water block on.

I'd recommend MX-4 or Artic Silver 5. Hopefully that and following the info above will get your results.
