Is there anything more I can do? - Page 2

post #11 of 26
Thread Starter 
I am right around 31°C idle. After two minutes of CPU Burn In (running two instances of it) i was at 48°C. I tried again and ran both for 5 minutes and got up to 51°C. I have seen temps up to 55°C when playing a game and running Prime95 in the background.

Would you say that the Typhoon is better than the ZALMAN CNPS9500 or the THERMALRIGHT XP-120?

Your temps are good. To be honest I dont think its the temps that are holding you back. Did 260x10 work? I'd say the Typhoon is by far the best air cooler. 2.6 ghz is the highest 75% of the x2's get to. I dont think you could reach 2.7 stable even with the big typhoon anyways but if you got a DFI the max voltage would be alot higher, like 1.8. Id say the highest safe voltage on air is 1.65.

My brother has the 4400+ X2 on a DFI RDX-200 CF-DR and it hits 2.75 with I think 1.425 or 1.438vCore so I am having a hard time believing that yours is having difficulties at such a "low" overclock with 1.500 vCore, try to set the vCore to 1.400 and see how high you OC with that, I did notice that I got a higher overclock with 1.425v than 1.550v, which was weird.

Also, pandapimp, Asus mobos support X2 CPUs out of the box because they come with the lastest BIOSes preinstalled while DFIs always ship with the first BIOS release, as far as I have seen in the past atleast.

EDIT/// Are you sure your A8N-SLI only gives you vCore up to 1.5? Is there anything named CPU VID or VID control in your BIOS? I find it odd because my Asus P5N32-SLI Deluxe has up to 1.7vCore without even using the VID controls.

Try this, this is for A8N-SLI boards, note that it was posted by Shamino who, IMO, is the best overclocker in the world and I THINK he holds the current 3D Mark 05 record, anyways as you can see in the pic on the second page he is running 1.680vCore on his CPU so clearly this is not some baby step up!

I have yet to try the 260x10, I am at work but I will as soon as I get home in the AM. I believe I have tried it before, but maybe I didn't spend enough time working to get it stable. I will let you know how it works out!

It is interesting that the X2 max out so soon, but it did seem like that was turning out to be the case versus some of the single cores people were using. Maybe at some point I will look into getting an older single core chip system setup so I can mess around with OC'ing a bit more. And maybe move to a DFI board if I can get rid of my Asus.

Thanks again for your help!

If you want to push some more out of your X2 check out the link I provided above to increase your vCore, vDimm and Chipset voltages. *I think it would be wise for me to say that I take no credit nor blame for anything that happens voltmodding is dangerous and actually pretty irresponsible, but yes I would do it if my mobo didn't already give me way too much voltage* anyways, if you go single core AMD s939, I would get a 3000+ Venice for cheap or a 3700+ San Diego if you actually plan to use the system and not just sell the CPU once you are done OCing it, if you happen to have gobs of cash, it seems that the new FX60 is a VERY good overclocker, hitting 3.2GHz with the stock AMD heatsink in a review I read yesterday.

"Without much trouble we reached 3GHz with stock voltages. Upping the voltage to 1.5 we were able to reach just under 3.2GHz. We are working on a more thorough set of overclocking tests including high end air, and phase change cooling."

They did use water cooling but note that he said 3GHz on stock voltages so that means even the stock heatsink should do fine, 1.5vCore would still be fine with the stock heatsink. Judging by the CPUz SS I would say that the stock voltage is 1.3125 (1.312 in CPUz) which is astoundingly low, especially considering they hit 3GHz without touching it!

Yeah, it definitely goes up to only 1.5v. I have heard that v1008 (i believe) allowed it up to 1.55v. I am running 230x11 at 1.475v right now. I have tried to notch it down but definitely is unstable at even one notch less than this. I am thinking that this may even be unstable because I have had a few errors when running the regular Prime95 backround program (non-torture) every 10 hours or so.

I am away from my system now, so I will check when I get home, but I dont remember seeing any VID control options.

Off the top of my head I am not sure how high I got OC'ing with a lower vcore, but I will test again and let you know. However, I can only go to 232x11 by bumping up to 1.5v, and that leaves me in the high 50's as far as temp goes. Maybe I have a faulty MB or something??

I have seen this before and am tempted to try it. However, I may not be brave enough yet I probably need to hone my soldering skills first. Seems like a good project though that I may tackle at some point for the sake of more speed and a new experience!

Heed Red's suggestion on the oddity of higher OCing with lower vcore settings.
I've been spreading the word on that w/re, to the Optys but the more I read the more I'm convinced that the 939 in general don't need to be force fed high volts!

Good call, I will do a little more experimenting. Any possibility that the AUTO vcore setting could actually be helpful on these boards? Or stick to manual?

No dice running 260x10 with max voltages on all settings, minimum voltages, dividers or not. I can't get more than a minute into Prime95 before I get an error.

I also tried going back to my 230x11 stable OC and lowering the voltages. Stock wont allow me too boot, and I need to get back up to at least 1.475v to be stable. To answer my own question before, AUTO on vcore definitely does not work!

Looks like I may be stuck at my 230x11 unless I do the hard wire mod, or use the other clockgen mod that I saw on here to get more volts and maybe switch over to water cooling.
