Did you lower you LDP multiplier from x5 to x4?

LPD? MUltiplier? Is it the one with X1-10? Which should i lower it? BIOS?

based on ur mobo, i dont think the problem comes from pci freq unlock.. how bout ur HTT multiplier? u must make sure ur HTT x htt multiplier = 1000 or below.

let say ur HTT is 200, the default htt multiplier is 5x, so 200x5 = 1000. that is default. if u increase ut htt to 220 for example, u've to drop ur multiplier from 5x to 4x.. so that it become 880 (220x4).

201-249 use 4x
250-299 use 3x .. n go on

other tips for oc is increase ur HTT / clockspeed first before increasing ur vcore. goes into windows to test the stability using benchmarks program n if stable go back to bios n increase ur clockspeed again. if the benchmarks program fail or windows cant boot, increase ur vcore step by step. then go back into windows to test the stability. Repeat this until u find ur max oc or u r satisfy with ur oc.

n if u r using el cheapo ram aka non high performance ram, u've to loose ur ram timing. the loosest' timing is 3-4-4-8.

n if u think that ur ram is holding ur processor potential oc, and u want to oc ur processor alone, use ram ratio. set ur ram to either ddr 333, 266 or whatever setting in ur board.. use this website for ur reference :

hope it helps a lil bit



i think it is LDT (/HTT) multiplier. u can find it in bios. it has setting with x1,x2,x3,x4,x5 and auto.

Whoa great!!!!!!!!!!!!!!!!!!!!!! Thx a lot everyone!!!!! Whoaaaa precious suggestion and guides! I really aprreaciate it!!!!! But then i haven't install any cpu fans. I use the orginally fans from the AMD box one...... Is it fine?

Yeah, you should be able to do some overclocking by just using the stock HSF. I've just installed my X2 3800+ and I'm testing it using the stock HSF right now

afaik X2s use the heatpiped AMD heatsink.. those are better than other stock amd heatsink.. should be fine for mild overclock

That's for the higher speed X2. The X2 3800+ comes with the normal stock AMD HSF

Wow... So arj, u havin 2 rigs now..? FX and X2..?

I have 2 rigs for quite some time already. Removed the specs of my Work Rig to make way for the Battlefield 2 signature

Owh.. I didn't noe..

LoL... So which rig you say is best for performance : price ratio..?

AMD Athlon64 X2?

Between the FX-55 and the X2 3800+, I'd definitely say the X2 since it's an all-round processor. Excellent for multi-tasking stuff and not to shabby for gaming. Waaay cheaper than the FX too.

Whoa! It works! Thx Extram Newbie! But the load temp could reach 52c and idle temp is around 42c. So is this normal range temp.? Will it harm the CPU? I set the cpu voltage for 1.4v and overclocked till 2.2ghz...... Is that fine? Or i should raise the voltage? And where can i get those stress test software?

haha damn.. that heatsink on that hot mofo

That's nice to hear..

Just google and search for Prime95 or SuperPI..

what a bad news, installed the new DFI-NF4-UD and 7800GT, when pluging the power suply, found out that the mobo is using 24 pin, then go to C-Zone to get a converter, but the fxxking thing is, when i on the power supply, not turn on mobo yet, the power supply will beep for long time, changed to another Enermax 300W, samething happend, I just dont know why the PSU will beep for long time.

now take out the whole mobo from the case, put back the old system, everything work fine...

i suspect it might be the converter problem, i would like to know is there any differences between 24-to-20 converter and 20-to-24 converter?? are there both same or different? the convertor wiring looks very strange when i compare the actually 20 pin and 24 pin PDU diagram.... the convertor looks like wired opposite way...

Power supply beeps? Never heard that one before. Have you tried plugging in the 20-pin PSU directly to the motherboard without a converter? If you have a good PSU, it shouldn't be a problem to use a 20-pin PSU with the DFI board. My friend is using a 20-pin Antec and he's using it with his DFI board for a few months already without any problems.

X2 3800+ overclocking update time......

Here's where I'm at right now with stock vcore and HSF. Will let it run overnight with two instances of Folding@Home and will continue to push it further tomorrow

can somebody tell me is there any different between 20-to-24 and 24-to-20 convertor? been looking on internet but cannot found....

ahh....nicely warm.
wat cooling? (If i missed it ,sorry)

Me? Stock HSF at the moment

you need all 4 power connectors to be connected..

the 24pin ATX, P4, Floppy and Molex

i've seen cases where X2 system won't boot without that 2
