currently running my AMD X2 3800+ @ 2430MHz 1.6v (stable for more than 24 hours prime and memtest), and the motherboard is Gigabyte K8NS Ultra 939.



with my current water cooling set, prime for 24 hours and the temperature is maintain about 54C, without aircond, if i on my aircond, the temperature is about 48C.

i was told that gigabyte is not good for OC, I am planning to get a DFI NF4, and a new 7800GT PCI-E. I am wondering, will this new motherboard can help me OC more with lower voltage?

I had tested so many combination of the BIOS configuration, and my RAM for sure can do DDR520 2.7v 3-4-4-8-1T, i just dont know why my CPU can't OC more....

need your guru suggestion, will the new DFI NF4 help? and which model should I go? I will buy a 7800GT PCI-E at the same time, but my budget for the mobo is around RM600 only.

that vcore's pretty high for a 3800+ to get 2.4ghz

what's the steppings of your cpu?

the stepping is as show on my first attachement.

but the CPU is actually a Toledo 512KB version, which is 1MB disabled unit.

babyelf means the stepping code on top of the IHS of the CPU.

if you haven't checked the steppings how'd u know?

Wat's a safe voltage for a processor actually..?

The CPU-Z dispaly the proc as Manchester, but, how do you know it is Toledo? is it CDBOX and BVBOX thingy? I've heard somebody told me the same thing too, which the CPU-Z display the wrong info. By the way, here's mine, donno Manchester or Toledo screen shot @ 2500MHz @ 1.39V, Currently priming at 1.38V. water cooled with homemade water block Max load @ 43C, at sunny day and non-air conditioned room.

latest everest ultimate edition reported Toledo-512, and the batch is something end with AA5CD, and forumer from Anandtech said ending with CD usually is a disabled toledo.

can anyone tell me will the DFI NF4 have a better oc than my current mobo?

why not use 10x multiplier? with w/cooling i suppose u dont need to drop the multiplier.... or maybe the HT multiplier?

1.392v voltage only... Impressive.. My Athlon64 3000+ over 1.5v adi.. =\

CD is E6

my experience.. DFI will give better overclock and will have a higher HTT limit..

NF3 Ultra Chipset might have problems reaching too high of a HTT for you to clock it too high with a 9 multiplier..

and i do'nt recall gigabyte giving the option of increasing the chipset and ldt voltage to gain more mhz..

it could very well be your HTT holding you back.. and pumping more vcore won't get you any further

But if you upgrade to DFI, then you need to upgrade your RAM as well, because AFAIK, DFI NF4 LP not friendly with CT or BT-d43.
Haha... quite happy with it, i'm now dual priming at 1.375v for almost 9 hours now.. hope can pass 23-24 hours.

babyelf, ok, thank very much for your suggestion, i will go for DFI!

Be careful as I see you are using D43 RAM. It is known to usually have problems with our el cheapo D43 RAMs. That was the reason I didn't get the DFI in the first place.

Secondly, HTT normally works upto 1GHz. So please check if your HTT multiplier is dropped to 4x instead of the default 5x if you raise your HTT beyond 200.

my HTT now is at 3x for 270MHz.

what about the Abit Fatality you are using? good oc?

talking about OC, i will prepfer DFI, but i dont know which model to go, can somebody tell me? thanks.

Not sure whether it is good or not but it is quite stable so far. But there are a lot of people here who would swear by DFI if you are talking about overclocking.

For Abit, it is more tolerant of cheap RAM and recently I tried even 2 pcs of 512MB and 2pcs of 256MB RAM and it worked although it has to run 4 pcs at 2T. Other than that, it has front cmos reset which is really convenient for overclockers to OC a bit too much.

just got my DFI LP UD, and a 7800GT.

i decided to go for UD instead of SLI-D because some one told me UD is confirm modable to SLI-D, and i will mod it one year later, since modding will void warranty!

going to assemble it now, hope can get better result.

The bridge will cost you at least RM50 and last time I checked, it's not easily available locally while a conductive pen from Jalan Pasar will cost you RM100+. At the end of the day, it is not cost effective at all buying an Ultra-D to mod it to SLI-D.Then there's also the risk that the mod will not be successful.

I'm having problem overclock my AMD Athlon 64 3800x2....

Here's mY Computer tech:
1. CPU: AMD Athlon 64 3800+ x2
2. Harddrive: Western Digital Cavier 250GB Sata 2
3. Motherboard: ASUS A8N-SLI Premium
4. GPU: 1X MSI Geforce 7800GT TD256

By adjusted the CPU Voltage from default 1.3v to 1.4. From 2.0GHZ to 2.15GHZ. Everything seems ok. The idle temp is around 40c and load temp is around 52c. But after i adjusted the CPU voltage ffrom 1.4 to 1.425 watt. And CPU frequency from 2.15ghz to 2.2ghz. The system just crash and show that i need to insert XP cd's coz some files are missing and said need to repair. But after i set the voltage and frequency to 2.15GHZ and 1.4volt. Everything seems fine. So i wondered wut's wrong? Temparature too high? Volt too high? Or???
