Overclocking. I know how to do it but results are odd?

[dannyboy2005]

I have asked on a few computer forums on how to overclock.

I now know how to do it but seemed to have a issue.

I have a ASUS A8N-SLI DELUXE with AMD ATHLON 4800+ X2 (2.4ghz) SKT 939 and 4GB Ram

i can only get my processor to OC to 2.6Ghz BEFORE the blue screen hits and have to down grade.

Now, i've asked on a few forums but no one wants to help cos your a 'n00b' with not many post counts (The fact i've got many many other forums to visit other then theirs makes me a n00b?)

You guys on here seem knowledgeable and very helpful to say the least.

I want to know IF it is POSSIBLE to go any more then 2.6Ghz before it bottles out? If so how to do it?

I forgot to mention, i'm running a Artic Cool CPU cooler and have several cooling fans. Iirc (From memory) the CPU atm, now at 2.6Ghz (O/c) runs at around 50*C ?

Thanks

I think you'll get more help at Anandtech, Overclockers or Extreme since this a software forum.

In a nutshell; there is lots more to o/c ing than just cooling. RAM timings and tweaks, BIOS settings, individual cpu's and motherboard characteristics all combine to produce exceptional overclocks.

So if you aren't getting the answers you hope for, it may be that your question is too broad. Do a bit more digging into your specifics and refine the questions and you may find others more willing to invest in your solutions.

No, you reached the limit of your hardware once you get a BSOD. Going any higher is not going to happen.

Unfortunately I have zero experience Overclocking AMD chips so I can't really help you apart from suggesting you either need more vcore or loosen your RAM timings/speed.

But it appears you are close to your max vcore as it is.

I honestly couldn't say whether you at your 'wall' or not

Since you have an asus board there should be the over clock setting in the bios correct?
What options do you have?

 

[Etihtsarom]

Overclocking is really all about voltages. If you reached that speed at stock volts, give the board, the CPU and the ram more volts. And make sure you cool it well.

Overclocking

To gain better overclock results for AMD CPU

it's important before you start to overclock that you make sure you are starting out with the correct minimum voltages for your hardware.

now in the bios:

take the hyperthreading off of auto and set it to X 3 then lower the ram speed below it's rated max aka memory divider you may have to play with this but don't worry your overclock will more than make up for lowering the ram speed because as you overclock the ram runs faster.

Now you can raise your front side buss slowly a few mhz at a time and reboot each time till your computer does not post all the way then go back in and lower the front side buss a notch or two until it will post now you know your max FSB

Now this is where you can bump up the voltage if you want to try to get a little more speed just be careful here you don't want to increase the voltage to much and proper cooling is a must but bump your ram and cpu voltages just a tad then try to raise the FSB a few more notches and see if it will post if it will keep trying to raise the FSB untill it won't post again then you can try another voltage bump but BE CAREFUL! not to much voltage it helps to know the max rated voltage on your ram and cpu I try not to exceed it you usually have some room between minimum and maximum voltages I never recommend going over max unless you water cool good luck and have fun

Overclocking

You can also relax your ram timings and various other ram settings to achieve better overclocks as well depends on what settings your board gives you for ram settings it helps to have an overclocker friendly board and some good ram

Those old S939 X2 are not big overclockers. I have one in my workshop PC and the most I could get out from it was 2.9GHz but it wasn't stable enough for 24/7 use and it needed a significant increase in Vcore: CPU-Z Validator 3.1

I would keep it at stock speeds just to avoid damage to the CPU.

First off, i know little about overclocking AMD's so others can offer better advice there.

However, some general rules of thumb that i think applies to both AMD and Intel:

1. Research and make sure you know the MIN-MAX VCore voltages for your CPU, RAM, before you make any voltage adjustments. Exceed MAX recommended at your own risk. This is very important and the 1st thing you should know before doing anything.

2. Know your thermal limits of the chip, and keep a close eye on temperatures at all times.

3. have a goal in mind, but nothing to excessive. Generally speaking a 20% OC is good goal to start with. (this may be a bit lower with earlier AMDs Im unsure)

4.Also, when trying to find a good stable OC for CPU, it helps to underclock certain hardware.
I/E while looking for CPU OC, youll want the RAm underclocked so its not a issue.
When adjusting the RAm & timings, youll want to lower the CPU muliti until your sure the RAM is stable.

You'll need to work with 1 thing at a time so you'll know exactly what part the instability/BSOD is occuring in.
Many new overclockers, or those just learning want to start turning up CPU clock then ask why is it BSODing, or what to change.
By tuning one thing at a time, youll know what the culprit is.

And finally, Overclocking takes time, and a lot of trial and error.
Be patient and be careful, and watch the temps and voltage.

hopefully some of this will be a little help. Sorry i couldn't offer anything more.

This isn't just a software forum, what is the sub-category that this thread is in? Performance and maintenance. I know that that are a lot of people here who know how to overclock. Just look at this thread : http://www.sevenforums.com/performance-maintenance/2309-post-your-overclock.html. Just my point of view,

Dom

If you're serious about it here is a little light reading on overclocking for socket 939,

A64 Overclocking (Socket 754, 939) Intro Icrontic Tech

P.S. Did you remember to lower both the HTT and the memory divider? You need to lower both, then work on finding the max CPU overclock, then you can work the meory divider back up. Keep the HTT to less than 1000 (HT Link in CPU-Z).

This little tool,

Download A64Calc.rar

will help with figuring out the numbers. Just to give you an idea I ran an old x2 3800+ at the following,



for close to two years.

take the hyperthreading off

Soz computersplus I don't like to correct peeps but I'm sure you meant "Hyper Transport" AMD X2 don't do "HyperThreading" --- just 2 avoid confusion

But I agree the X2's weren't very stable when Oc'ing

Thanks your are right my mistake see what happens when you only sleep for a few hours each night lol....

when you increase the bus speed, the ram and ht link goes up too. so, along with downclocking your ram, you might need to tune the ht link down to x4. whenever you get the ht link above its 1ghz freq, you're prone to bsods. some boards are more finnicky than others.
(just saw that i repeated the same thing as stormy13)
