Help with Overclocking Amd X2 4200

[Dashock]

Hi all i hope someone can help me take this chip to the next level as the most i have been able to get with this chip is 2.625ghz and this setting is done with a multiplier of 10.5

At 11 Multiplier its almost hopeless after i hit 2.4 ghz
Setting right now




My Gear
Amd X2 4200 939 Manchestor Core
Asus A8n-Sli Deluxe Rev2
OCZ GameXstream 600 watts
OCZ DDR-400 Performance 2gb kit at 2.5,3,3,8 at 1T

anyways i been using 1.4625 volts to achieve this 2.6ghz i found a sweet spot at 10 multiplier as well but again the chip is not stable more then 2.6 i got it to boot to 2.8 but after 25 mins it just locks up do you think i put the multiplier down more to say 9 or 8 i would have better luck ??? my issue is im putting a lot of volts on this thing i hoping to achieve atleast 2.7ghz stable attleast because i want to last me atleast the end of the year.




So if anyone has experience with this board or chip that would be awesome im just tryin to get the most outta my chip thanx yeall!

if the focus of your system is on CPU-Z use Alt+ Prt Scr to put just the CPU-Z window on the clipboard ... far less distracting than all the background stuff you've posted

Are you dropping the memory really low in speed to check for max cpu speed, and vice-versa?
And stability testing with prime95 (dual-core)?

I usually don't bother with much voltage increase, once you have to start ramping the voltage up for stability, it takes a lot of voltage for relatively small MHz gains.

I had a 3800+ Manchester on my DFI SLI-D, it topped out at 2.6, ran with nice low voltage at 2.4 GHz. Currently running a 3800+ Toledo, getting 2.8 GHz with this one.

Did you try dropping the 1t setting on your memory to remove it from the mix?

It's been a while since I played with an AMD rig, but I remember that being something that could make a huge difference in stability while in the initial overclocking phase. I suspect it's because of the integrated memory controller.

I'm not suggesting leaving it at 2t (makes a huge difference in memory performance) but if it's holding back your OC, you can beat the crap out of the proc, and them come back to tweak the memory settings to allow for 1t.

1T makes little difference in real world use and you would never notice the difference in anything except benchmarks. You get maybe a 3-5% boost at the most. Switch it to 2T and stability will be easier to get for the memory. I would not bother even trying to get it 1T stable ever, just not worth the effort at all.

This is a S939 rig here, so DDR1. Going to 2T on S939 systems doesn't usually make a whole lot of difference in performance, and even less in stability for a given clockspeed.

I would generally run 1T with 2 sticks, and 2T with 4 sticks, as that's all the mem controller can cope with.

[Dashock]

Im going to try dropping it to 2t to see if it makes a difference the ram is pretty good can do ddr 440 in 1t and ddr 460 is the max i put it to under 2T right now i went down to 10 multiplier i think this chip reallly likes this multiplier but i will bump it up to 2.7 again to see if i can get it stable .

[Dashock]

I wishh ohh i wish i had a toledo chip i hear those clock a lot better wish i knew half the stuff i know now back then would have helped i paid 300 dollars for this chip lol right after it went down from 500 to 300

put your mem on a low divider and concentrate on the cpu. raise volt a bit along with the FSB

then put cpu on low multi, and leave the ram @ 1:1. then raise FSB 2-3mhz at the time and run memtest, if memetest put out error, put slacker timing or try dropping frm 1T to 2T.

also add a couple V to the ram but not to much, personnaly i wouldnt expect that much from that OCZ performance series., those arae like all other compagnie Value select stuff but with nice copper heatsink ..... ....


personnaly i would keep the ram on a divider and concentrate on the CPU, (BTW those 4200+ wheren't the best overlcoker in the world ..... my firned had one and it was topping 2 2.5Ghz, so far 2.6 on that chip is a nice acheivement)

since the ram divider dont realy decrease performance of the A64 system, like ive already said, keep ram @ stock speed with a divider and increase the cpu speed.


once you have play long enough with those A64 cpu, you can acheive nice OC in a few minutes.

got my 165 opty to 2.7 in less then 30min, and it wwas prime stable for 8hrs ... also got Para_Frank 5600+ to 3.25 i n less then 1 hrs ....

I know a lot of people cant even get 2.6ghz outta this chip but i think there should be more outta of this chip call it going on hopes and dreams what would you recommend to volt the ram to right now its sitting at 2.6 stock is 2.5?
