Oc X2 3800+ A8r

Alright heres the deal i have an Asus A8R-32 MVP Deluxe and a 939 3800+ X2. Just recently i purchased the nice big zalman cooler for the thing. The big one with lots of fins and heatpipes. Now im idling at around 42-44 and i know load gets to about 48 so i believe i have some breathing room. Can anyone tell me some good settings? This asus overclocking friendly bios is just too much for me.

 

Does anyone even have this mobo or a A8N as it probably has some of the same features. AI Overclocking is my problem.

 

With very good cooling and some tweaking, I've seen 2.8Ghz with a 1.375 Vcore. If you want to get around the AI Overclocking, just set it to manual and you will then be able to make adjustments yourself.

A little advice, disable everything you don't need in the BIOS: USB Legacy, Controllers - IDE, JMicron, SATA ports, raid and so on You get the idea. Less chance of conflicts. Find out what timings your memory runs at and set them manually as well. And to start, try out an auto setting for your voltages and then make manual adjustments if you need to.

 

Ok i will try this when i have a lil time and get back to you. thanks for the tips!

 

Ok so i did a ver ybasic set ram to 400 to keep it there and set multiplier to 10x and clock to 223 and getting 2.23 per core. Now this is with stock voltage. If i get to 230 it fails the oc. If i increase the voltage will it let me go higher? ANd if so what voltage would u suggest. id like to get 2.4 or 2.3 if possible. id be happy!

 

yes, increasing the voltage will let it go higher. dont increase it more than a notch or 2 though, its really easy to overvolt your CPU. up the voltage in the smallest increments possible until you reach stability. try to keep the voltages within 15% of the stock voltages though, anything over that will (further) decrease the life of your CPU

 

Viper's right. Upping the voltage allows for higher clock speeds, but also decreases the life of your processor and kicks up the heat output. Don't worry about the life of the processor that much though unless you plan on keeping it for a very long time. And make sure you keep an eye on your temperatures as the processor will run hotter than it is now with a higher voltage.

 

If you want some More Help post all your system specs, what kind of memory are your running? what PSU?
You dont need to run your memory 1:1 with a 939 what matters most is Max MHz

Your x2 3800 should do 2.5GHz with ease, with some great memory, good PSU and some work 2.7 maybe even 3ghz is very possible.

First thing I noticed your idle temps are on the High side, Might need to look into that, to find your true Max load and to test for stability you should run Orthos http://sp2004.fre3.com/beta/beta2.htm this will test & run both cores & memory at the same time Keep an eye on temps though
If you keep your Max temps under 50c your CPU life Will Not Suffer

If your running pc3200 set your memory at 333, then manually set you multiplier at 10x, voltage I'd manually set to 1.4v to start, then start raising the cpu fsb
The CPU Voltage 1.4 should be good for up around 2.4Ghz/2.5Ghz

Here's some info on OCing an x2 3800 http://www.legitreviews.com/article/229/2/

 

thanks for all your help guys once i get home from school today ill be going for it.

 

Im running 2 sticks of 2.5 CAS pc3200 Corsair Value ram. And a 500 Watt Blue Aspire psu. A8R32-MVP Deluxe and the 3800X2

 

i left the ram setting to auto and it set it to 333 so i think thats good my voltage is 1.35 and i can only got to a max of 1.4.

 

its running orthos at 2223 and my temp is 48. soz for the triple post

 

Ok i set my my voltage to 1.375 the only step btwn 1.35 and 1.4 and i set the external clock to 240 with a 10x mulitplier i set RAM to atuo and it is running at 333. Under full load in Orthos im getting 50-51 C which is pretty high i think. Its clocking in at 2.4ghz. what do you think? I idle at like 36 which is like always.

 

Good news after a few hours of gaming no ocing related problems and ive found while gaming my processor only gets to about 44! Which is well within my limits.

 

While running Orthos 51 c is fine

36 Idle 44c while gaming thats fine


To be sure your stable run Orthos for 8 hrs then run some 3Dmark benchies if you can do that & keep you max Load temp's in low 50's You can consider your OC Stable


You might be able to improve your temps several ways, Your fine but cooler is always better.
You can try to run the CPU Volts at stock speed, this will probably lower couple degrees but if you have stability problems raise it back up,
1.4 is no problem for your chip
Keep your PC clean
Make sure you have good case air flow / air exchange
add some case fans or replace the ones you have with high flo fans
You might be able to shave a few degrees by laping your CPU HS
Might also see improved cpu temps with better CPU fan


I have to Warn you
Aspire PSU's are probably the Worst on the Planet, I would replace it before it Dies or Kill's any of your other hardware
The PSU is the Most important piece of hardware in any system OCed or not

 

I can relate to this. When I built my first system, I cheeped out on a power supply and had it blow up (literally) sending sparks and smoke everywhere when I was playing Metal of Honor. Thankfully, it didn't fry anything else!

 

Lol yeas its holding me over to R600 when ill probably get that nice corsair psu. I have the massive 92mm Zalmann cooler on my processer wit harctic silver, the problem is when i had my comp downstairs my idle would be 29 and load 36 but i just moved up into my room so my idles is 34-36 now. And i bought a thing of compressed air and blast it out every day or too. Surprising how must dust is there that you cant even see.

 

Im happy with the stability i have at 2.4ghz and no problems so i will probbly go to 2.5 for an even 5ghz and call it a day. I really suck at this double posting thing.

 

LOL
It doesnt work that way

 

In my little world if i have 2 cores at 2.5 it equals 5ghz lol. so shhhhhh. Or you could explain! Enlighten me! Oh yea im at 2.5 and everything is just fine. No temp difference btwn 2.4 and 2.5.

 

Doesn't it feel good with a little OC:major

Get your self some PC4000/DDR500 memory & good Quality PSU you'll have the tools to get you near 3Ghz
Might need some cooling improvements
____________________________________

Here's an Asus I just gave a mild OC too, 2.5GHZ makes her a bit Snappier
My screen shot's show my stability test results of 8+ hr of Orthos and all the 3DMark benchies, if you can pass all the same test as me your system IMO would be Stable
My Max temp was during Orthos, it would fluctuate between 49c to 52c
During 3Dmarks Max CPU temp mid 40's, my VC would max about 70c, idle mid 40's
My idle is about 31-32c

can u give me a psu suggestion that will run my processor the same but also run a single R600? Price range of around 150 if possible.

 

off topic here but ASUS i got my 6800XTreme up to 480/1300 no artifacts after quite a while of ATItool stress testing and some 3dmark runs. also, with my setup p4 3.0 @ 3.6, pc4100 2.5-3-3-6 w/ the video card OC i got almost 12000 on 3dmark03. shouldnt urs be a bit higher?

good work on the OC vash, lookin' very nice

 

one question with my ram at 333 what going on there is that a super oc of my normal 3200 ram or what?

 

no, its underclocking it to compensate for the raising of the FSB which should bring it back up to about 400. when i set mine at 333 and ran my p4 3.0 @ 3.6 it would get back up to pc3100 (not sure about the actual mhz) but its just below the stock speed of pc3200.

 

This allow's you to crank up the CPU Frequency while keeping the memory within speed's it can run at.

Example the memory I used is nothing special it is PC3200 ddr 400 but it will not run 1Mhz over 400 so by setting it at 333 this gives me some headroom to raise the CPU Mhz/Frequency
When you raise the CPU Frequency, the Memory FSB goes up
Your CPU & MOBO can support much hicher speeds than your memory

some pc3200 memory can OC nicely


Did you read the OCing guide sticky at the top of the page http://forums.majorgeeks.com/showthread.php?t=52812
or the Link I posted earlier

Here's one of the Best 939 OC guides, geared more to DFI A64 MOBO's but applies to all http://www.diy-street.com/forum/showthread.php?t=20823

 

ATI -tool is nice tool to find artifacts

My card will OC much higher, get's hotter too.

My intent wasnt to find the fastest 3d score, more of Stability thing & to help vash2051

If I wanted fast I'd buy a better VC

That benchie may have been at stock I usually run my VC at stock.
I'm not really a Gamer

I know I was at 400/1201 for 3Dmark2001se
I dont know for sure if VC was OCed for the other 3D's, I use a manual setting with Riva-Tuner & I dont save it, a reboot would have set my VC back to stock, I dont remember, I'd have to run em again to know for sure.

 

Lol i read some of it its just nice to have someone explain it like that personally. Thanks! Rating of this cheap ram>>> http://www.newegg.com/Product/Product.aspx?Item=N82E16820231047 ?? Im getting it over some normal 3 Cas Value select cuz it has red heat spreaders and will go nicely with the rest of my look. It seems to be nicer ram also.
