Hey friends please help me out!

Ok… so I'm going to be as detailed as possible! Obviously I'm a noob and I'm super lost lol! I'm trying to over clock my CPU to a stable 4.1mhz-4.2mhz I prefer 4.2mhz I will start with my specs first to give you guys an idea what I'm working with.

MOBO: Asus Sabertooth 990fx
CPU: FX-8320 (clocked at 4.0)
COOLER: Corsair H55 water cooler (please tell me if this cooler can't accomplish 4.2mhz)
GPU: EVGA GTX 760 2gb (SC)
PSU: Corsair 750watt gold
OS: Windows 7 Premium
CASE FANS: 5

Alright with that ^ out the way this is my problem... Please go easy like dump stupid easy no abbreviations PLEASE! Unless they are terms that can clearly be seen on my motherboard. Like CPU……lol right now as we speak my CPU is sitting at 4.2mhz with 1.26v I noticed that when I went from 1.45v to 1.26v heat when down A LOT! But I'm still running very hot! I ran prim95 for 10-15min and already was at like 65c-67c I just found out that the more volts you push the more heat you get! I'm telling you guys I'm new at this I'm not joking =) but I think for some reason 1.26v is very low and it might affect performance! So I don't want to keep lowering the volts! Unless it's a good thing?? Another thing when over clocking do I only focused on 2 things? CPU multiplier and voltages? Like what are NB voltage and all that other extra stuff??... I have disabled all the power saving stuff and AMD turbo crap and so on... I've done a lot of reading but nothing is dummy proof everything has abbreviations I don't understand... Please if someone is kind enough to give me a break down in your own words that would be easy to understand I would really appreciate that! One last thing I promise. I'm volts are at 1.26 and still hot everything else is on auto... Maybe something else has too much voltage causing the overheating? Like NB which I don't know what that is but noticed a lot of people talking about it in over clocking forms... Thanks for ready and all the help!

I don't think that is very appropriate.

I found it gross but whatever. You need to post screenshots like the guys asked you at the other forum where you started a thread. It is work on your part. If you want real help you will do it.

Your right its overboard it was funny at first... But now its not.. But back on the reason I'm here I haven't had the chance to do that yet. I was at work. Did you have any tips? Or just policing around? I understand if you are no biggy ?

Right off the bat you need a better cpu cooler. Like I said, you need to post screen shots of hardware monitor after stressing your rig for 20 minutes using Prime95 to see your temps, voltages, etc.. screenshots of all the tabs in CPU-Z etc.... Then I am sure the more knowledgeable posters here or elsewhere will help you. But they aren't going to do your legwork for you.

Cool thanks!! ? I'm not expecting them to do it for me but some tips help just to help me process things. As soon as I get home I'll do what he asked. Thanks for the time. And again sorry if you got grossed out just messin around.

Not to be rude, but this is your third thread in two days about the same thing. The more appropriate thing to do would be just continue on in the thread that you already started. Usually threads are more or less about one main topic. So if the question you are having is related to your original post then you should likely keep updating the original thread. This keeps the forum cleaner by having less duplicate threads, and also helps you because all participants in a thread are notified when a new post is added to that thread. So you'll get the same people coming back and helping instead of trying to generate new interest in the same topic.

That, and try to keep it age appropriate. OCN is a family friendly place, and we want to keep it that way.

Now that that is out of the way...

Voltage is most definitely directly connected with temperatures. The more voltage you use, the higher your temps will be. Too much voltage can cause heat issues (as you noticed), and can damage your chip. Too low of voltages make your system unstable (might not boot, might bluescreen, crash at random, corrupt your OS installation, etc). In general, higher clock speeds require more voltage to be stable. So you are in a sense balancing three things 1) Temperatures 2) Voltage and 3) Stability. You want the most stability, with the lowest voltage and temperature you can get (a simplification, but close enough for this simple explanation).

NB stands for North Bridge. The NB is what is used to communicate between the CPU and the IMC (Integrated Memory Controller). I've been away from things for a bit, but last I can remember was that NB overclocking did improve performance by a measurable amount on phenom II's, but that generally NB OCin hasn't been super productive for most FX chips. Other than that, I don't recall having to mess with it tons. Since you are just trying to overclock the CPU frequency right now, I wouldn't bother with adjusting the NB voltage.

Oh, and the cooler isn't great, but it should be fine for 4.2GHz

.

And finally, while I know you said you have read some, read up a bit more. There are many guides out there to help you learn the basics of overclocking, many written by members of OCN (I even wrote one for Phenom II's that can mostly apply to FX chips) that do a much better job of explaining things than anyone can do in a single post. I know I had to read through the guides I could find more than once before I even got the basic idea of what was going on. Eventually it sinks in though

Good luck with the OC, and let us know when you have more questions

First off I'd like to say thank you for an amazing reply I understand this a little better now
smile.gif
sorry for being inappropriate ? I was just Trying to be funny... But like I said to the last guy I apologize. And I respects everyone's views! This is my first time posting so I thought to get more ppl involved you post again.. How do I delete the other post? I don't want to give anyone a hard time.

really quick! When I installed my H55 2 days ago I smeared some of the thermal compound of not much but I did leave my finger prints on the block should I put new thermal paste?

UPDATE!

GOT MY CPU STABLE AT 4.2GHZ AT ONLY 1.23V!!!!!! ran prim95 for about 2hr and my CPU never went over 62c and package was 40c then I played 2 games of bf4 and titan fall everything is perfect no overheating at all. Ty for all the tips guys.

Its all good, we've all done something like it one time or another. And to be straight with you, I'm just trying to help you get off on the right foot, not give you a hard time

. OCN really is a great place to learn, and I'm glad to see you've got a good attitude about trying to fit in and keep this place excellent

You can delete/edit your post simply by clicking on the pencil icon on the bottom leftish side of the post, then just clicking save after your changes. Sadly, you can't edit things of yours that people already quoted, but you can at least take care of any random misspellings or failed attempts at humor

Also, the H55 is a solid cooler. Its no custom water cooling loop, but its pretty inline with good air coolers. From the sound of it, you did mess with the thermal paste. Its not so much that you touched it, that it the imprint of your thumb might have allowed air bubbles to get trapped in there when you seated the heatsink. So if you think your temps are high, I'd probably reseat it. At worst, the temps don't improve. At best, you might get a couple degrees lower temperature.

Also, if you want better temps out of the H55, you can also add another fan to it (called a "push - pull" setup). That is usually good for a few degrees C as well. And finally you can add higher performance fans if you're not too worried about the noise. Personally, I'd take one of those extra case fans and see if the push pull makes a difference in temps.

Excellent! That is REALLY low voltage. I just barely got a 8350 (yesterday in fact), and I think my stock voltage is higher than that. Now if you're interested you can keep trying to push the OC farther

Try 10-12 hours of Blend and then 10-12 of largeFFT and unless you got a really lucky chip, you will see it fail. 1.23v is very low for 4.2Ghz for most FX chips. Simply Prime95 takes time to show instability.

Many users nowdays run 60 minutes of Prime and they think they "passed"...

Looks good on internet forums though.

Many people don't even run Prime95 and say they have a stable 24/7 overclock!

Some people don't even boot at 1.2v I was reading that its not necessary to run prim that long because no one runs a PC 12 str8.. What's the benefits of tuning prim so long?

Thanks I'll get to editing as soon as I'm near my PC (on my phone now) I did mount the extra fan! And new paste I think it made a huge Difference and its running way cooler then before.

Yes, i never overclock, but i have noticed some crazy values from people who just want to celebrate their uber chip and they think that Prime is more or less useless... i 've seen crazy undervolting claims too...Especially in Thubans, i remember once a guy claiming so low voltages that it seemed almost a 65W chip. Of course he never provided a 10h run of Prime, so i don't believe he had a golden chip.

Up to a few years ago, the "Bible" of overclocking was requiring to pass 24hours straight Prime95, before claiming a stable overclock. In the most recent years, this has gone down to 30 minutes, in a race between users that only cared to post CPU-Z "validations" with higher clocks.

There is even a new "fashion" amongst FX users, that when their overclock can't pass Prime95, they blame the software and not their overclock. Oddly enough, other FX users manage to pass Prime95, so it can't be software problem.

The "benefit", is simply because the algorithms that are ran during Prime95, are not the same. If you look carefully, you will notice that they are different. And CPUs that aren't perfectly stable, will sooner or later fail in a different algorithm. I 've had undervolting attempts failing after 6 hours Prime. I 've had times where it would pass IBT but not Prime after 10 hours. Even more, i 've had times where it would pass Blend for 8 hours,but not largeFFT for less hours.

At the end, there are many users that are happy enough with "almost stable". But, to my experience, if you stress the CPU a lot, sooner or later, an instability in Prime, will show. A BSOD that happens once a month, a mysterious corruption of your windows installation, it can be anything. Then people go to fora and complain about software problems, that in reality were caused by their "non perfectly stable" overclock. Same applies with undervolting really...

The lowest booting voltage, oddly enough, is also motherboard dependent. The FX-6300 is stable at 1.185v on my Asrock 970 board, while needs 1.23v on my Gigabyte 970 board (at stock frequency).
But 1.23v for 4.2Ghz, sounds a bit too optimistic for me... It could happen in a very good chip, but unless you run Prime for 10h at least, you can't be really sure. As i said "old school" overclockers, before the trend of showing off CPU validations was out, used to run 24h Prime. I stop at 12h plus IBT, because undervolting is less complicated and haven't witnessed any instability doing so, despite putting full load on CPU for days non-stop.
