help needed to OC a 4600+

[kaver]

Hi guys here is the thing i want to overclock my CPU but im a litle over my head with this im very new to this overcloking business so i need some expert help

this is my configuration

AMD 64bit X2 4600+
1GB Kit HyperX DDR2 800MHZ Dual Channel
Asus M2R32-MVP AMD 580X CrossFire Chipset+ATI™ SB600
X1900XT 512MB
this part sucks 550W Viomax PSU (like 30 bucks)

I have only been able to go up to 2.64ghz that's a 10% increase stable

the hiest I have been able to go is 2.97 i think or close and i dont remember how, I was messing with the settigs and i was lucky i gues but my system crashed, what do you guys recommend I know temp is not a problem my CPU runs very cool air (small room with good air conditioning he he my private play space he he)

it runs at 25-30 idle and 30something max under load not close to 40 wile OC to 2.64ghz

I just use the overcloking utility in the motherboard to (AI noss) 10% increase

First off I would not use any Windows based program for my overclocking, you really should be doing that from the BIOS. First off you are going to want to test the limits of your CPU and take the memory out of the equation, then after you find your maximum CPU speed take it out of the equation and see how far you can take your memory.

So to test your CPU out go turn your memory divider (it will be set at DDR800, DDR667, DDR533, or DDR400) as low as you can. This will allow you to overclock your CPU without worry of your memory getting up to insane speeds. You should have a 12x multiplier for your CPU, slowly increase your CPU frequency. After each bump up in speed go back to your Desktop and run dual instances of Orthos Prime 95 for at least 6 minutes to test for stability, once you get your final overclock you will want to run Prime 95 for much longer but 6 minutes or so will be good enough for now. Dont forget you dont want your Hypertransport going much over 1000 so as you overclock also decrease your multiplier from 5x. Once you get into Windows and find a certain overclock unstable you will then want to go back into the BIOS and increase your Vcore in small increments until it gets stable and then continue to increase your CPU frequency until you need some more juice, I personally wouldn't go much over 1.5v.

After you have your highest CPU overclock go into your BIOS and and crank the settings way down for your CPU. Set your memory to DDR800 and play around with memory speeds until you find you find a stable speed. For testing your memory you should really grab Memtest86, it is bootable from either a floppy disc or a CD. After you find your maximum memory speed with the timings that you want it is then up to you to find the best mix of the two. This may look different for different people, some people just want the highest possible CPU overclock and they let their memory speed/timing suffer a little because of that; some people will run a much lower CPU overclock in order to run their memory as fast as possible with the tightest timings.

Just remember to get Memtest86 and run it before botting into Windows every time to check your memory stability and then after you get into Windows run dual instances of Orthos Prime 95 for at least 6 minutes. Then once you have the settings you want to keep, let Memtest86 run through 3 full sessions and run Orthos Prime 95 for 24 hours.

I just wanted to point out that AI NOS is a BIOS level OC'ing system. Also, even with tasandmnm's instructions, you probably won't get any higher than 2.8GHz. In fact, with my old 3800+ (single core version of 4600), I only hit 2.6 GHz. After about two years of that disappointing OC, I upgraded to an FX-60 @2.8GHz to max out my 939 socket. I believe there is a sticky specifically for OC'ing A64 on the hardware -> CPU(OC) page.

Well after messing with my settings here are my results

My CPU its a 4600+ dual core and i see you have the same CPU but is it Dual core also? cause i tried your settings but they dint work :-()

4600+ OC @ 2.639.76 FSB 1319mhz 10x264 temp idle @ 27-30c

memory HyperX 800mhz no OC on it

what do you think tasandmnm?

the only deference i have from my last OC is the FSB its much hier last time was 1100mhz now ist 1319!! is that bad?

its aparantly stable do


I couldnt find the way to increase the Voltage on my CPU do could that help to increase the OC?


tks
guys

 

[EXT64]

First off, there is no FSB for AMDs, it is Hypertransport (though it is often mislabeled as FSB). Was your stock HT/FSB 1000MHz? I know for my FX-60 and all of the 939 chips, you had to keep the HT/FSB as close to 1000MHz as possible. 1100MHz is okay, but 1300MHz (unless they changed something) is way too high.

You should be able to turn down your HT multiplier (you could on 939 boards). It must be below 1100 to be stable. HT link and ram stability issues got on my nerves so much that for my most recent OC I just increased the multiplier, a special feature of the FX line.

FX-60 @ 2.8GHz (x14 CPU Multi, 1000MHz HT)
A8N-SLI Deluxe
6800Ultra SLI
2GB Corsair XMS @ 2-3-3-6-1T 400MHz

well yes its hypertransport im just use to "FSB"

but yes I couldn’t get my processor more than 2.64 ghz so i tried getting a hier HT on it and it seem to work I ended with the 1319mhz

with a stable system played city of heroes for like 2 hours with no problems my only concern is to damage the motherboard

my load temperature was 45c max so i think im on the safe side with the processor

Does increasing the CPU voltage helps to OC more cause I couldn’t figure how to raise the Vcore

http://forums.extremeoverclocking.com/showthread.php?t=151373 This is the best guide I've found & check in practice, being a newbie to A64 OC.

 

[EXT64]

Increasing the core voltage can increase OC'ing results, however it is also the easiest way to damage the CPU if it is raised too high. My guess is, if you haven't already reached that chip's OC limit that the HT speed is limiting you. I know for my comp there was a system clock of 200MHz that everything was based off of. The rest was determinded by multipliers:
x5 for HT link (adjustable-1,2,3,4, or 5)
x2 for ram (could reduce w/ dividers)
x14 for CPU (1-25)
etc.
What I would recommmend for OC'ing is, if you can find them, turn down HT and ram speeds so they are always at or below stock so you know that the CPU is the limiting factor, though, if you can't change Vcore, you probably won't get much higher than 2.6 or 2.7GHz. But if you say that yours is stable at 1300MHz, they may have changed something. I thought, though, that the HT link for 939s was the same as that for the AM2s. But, if it is stable, it is probably safe.

From Asus site, about this mobo:

Designed for serious overclockers
It offers ways to raise system performance inch-by-inch and step-by-step to achieve maximum performance! This is about getting the most out of your machine and taking pride in your customized computer.

vDIMM - Take control of how much power is going into the memory modules. ASUS gives you 12-step voltage control to the DIMM
vCore - Find out "exactly" how much power your CPU needs. Fine-tune it with 0.025 volts at a time!

SFS (Stepless Frequency Selection) allows
- FSB tuning from 200MHz up to 400MHz at 1MHz increment
- PCI Express frequency tuning from 100MHz up to 150MHz at 1MHz increment

Tested @anandtech, December 2006:

it has offered excellent performance and fairly good overclocking rates up to 315HTT to date

 

[tasandmnm]

As others have pointed out you need to get that HT multiplier lower and keep your HT bus hopefully less than 1100 or so and you also need to find out how to crank up your Vcore, that is definitely why you arent getting over 2.64ghz. I can leave my Vcore alone and get right around that area too...but for anything more I have to increase the Vcore. When you first start increasing it take it slow; only raise it in the smallest amount that you possibly can and then go back and check for stability. Once you are stable, then go back in and increase your CPU speed until you need to increase your Vcore again. Eventually you will hit a brick wall probably in the 2.8-3.1ghz area. Then start bringing your RAM into the equation, etc etc.

 

[kaver]

Apparently I did reach a brick wall with this CPU cause my Vcore was automatically adjusted by the Motherboard to 1.5v when i checked the settings on my AIBoster it said 1.49 to 1.5v sometimes spiking to 2.71ghz on my CPU but only on full load and my temp reached no more than 47c at that point with the stock heat sink and fan

And it was stable played again for 3 hours CoH with no problems and with way better performance than before so that’s a plus

I guess my CPU its a crapy overcloker does anyone know if there is a better AMD CPU to overclock

Il also try to manage the Vcore manually see if I get better results with out having to go above 1.5V

4600+ Dual core AM2 89w

i gues ill stick to my Asus P5WDH DELUXE Digital home MOBO and get a E6300 to mess with

Haa... to OC or not to OC that is in deed the dilemma :roll:

 

[kaver]

Another think i forget to mention I have a a very crappy power suply so before I keep messing with my system ill get a good one

I have a Viomax 550w I paid 30dlls for it new

what PSU should i get? :roll:

 

[EXT64]

I would highly suggest reading the PS 101 and other pages on the Power supplies and cases page before choosing a new one. I have a couple of Ultra PSs that I bought because they had modular cabling that serve me well (I have a 550W version in my FX-60 computer), but I am sure you can do better with a little research.

One thing that I did notice is that you have the 89 watt version. I think tasandmnm had the 65W version. This may be part of the reason why his OC'ed better. As for a better OC'er, I don't think that it is really worth it. I know some of the new low end (3600 Brisbane) OC'ed like crazy and are cheap, but they would probably still top out at 2.9-3.1GHz. CPUs like mine top out (if I really pushed it, I was lazy this time) in the 3GHz range, but mine of course is 939 and no longer in production.
