What are your X2 4400 made of?

[Pyr0]

Sorry, no experience with this folding@home program. We use 2xprime95 for 8 hours. Post a screenshot with that

i primed it for more than 24 hours ages ago, i had a screenshot, but it seems imageshack has decided to screw with my images, now all i have is this stupid small thumbnail :confused: @%#£$

according to imageshack the pic is from Tue Sep 27 18:23:44 PDT 2005

 

like i said before i'm too lazy to do it all over again, i only have one rig together at the moment and it's constantly in use, so i don't really fancy being without a pc for the next day just for a screenie

until i get a new PSU you'll just have to take my word that it is prime stable for over 24 hours :

it never gets switched off and is rarely reset, unless i install a new driver or some software that requires a restart

[YeaYea&#33&#33&#33]

I wish I knew how to overclock. I want to so bad. That bloody guide confuses me.

peanutplanters,

 

does a 4200+ count? if so, im running at 270x10 = 2.7ghz at 1.49v

Not exactly. I open this thread to get people to post their 4400 oc results so I could compare. You can still post your results here. You should also post your results in the Overclocking Database and according to the rules of DFI-Street. I hope to see them.

ok...

i finally got round to installing my DFI Venus board last night, so i'm overclocking and testing for stability again before running folding@home

(don't want to loose points because of errors)

so for the time being i've just tried to duplicate my 24/7 clock managed on the SLI-D (2750MHz)

here's a screenie passing 12hrs of stressprime 2004, custom test using 800MB per core

it'll prolly be priming for another 12 hrs yet

 

drive strength is level 5 and data drive strength is level 1, tref 4708

 

had to increase the core voltage slightly (maybe something to do with the older lanparty boards overvolting under load), but my memory is running a little better with less voltage

 

[edit] this is with Tony's modded 0406 bios with the odd divisor correct option disabled

 

[edit] 24hrs prime stable

Pyr0,

 

How are you cooling that puppy? What are your volts set at? Thank's for any info.

1.568V watercooled with a swiftech storm and fans on low speed

Holly carp fish!!!!! No wonder my rig keeps puking at 10hr prime. I’m on air, Zalman7000 and my room temp is 17C. I guess it's going to take a lot more work.

 

I’ve been trying:

CPU FSB/HTT 250

CPU Multipler 11

Memory Divider 150

= 2750mhz @183.33 x 2 = 366.66 x 4 = DDR1466.64 failed

 

CPU FSB/HTT 306

CPU Multipler 9

Memory Divider 140

= 2754mhz @211.85 x 2 = 423.7 x 4 = DDR1694.8 failed

 

CPU FSB/HTT 250

CPU Multipler 11

Memory Divider 150

= 2750mhz @183.33 x 2 = 366.66 x 5 = DDR1833.33 failed

 

CPU FSB/HTT 306

CPU Multipler 9

Memory Divider 140

= 2754mhz @211.85 x 2 = 423.7 x 5 = DDR2118.5 failed

i could do 2750 on air with an xp-120 and a 120mm panaflo fan completely stable.

the temps were up around 56-57C in the summer tho, and the noise of the panaflo at high speed started getting to me

 

recently, as the weather has started to warm up a little, i've been thinking about cutting the ihs off it to keep the temps down

i tried it on an opteron 146 and found the load temps dropped approx 4-5C to 38C loaded at 3100MHz & 1.65V

 

it sounds like you may have found the max for your cpu

what voltage are you running through it?

 

if i take this cpu up to around 2850 it starts to flake out, although i've only gone up to 1.625V

[tasr]

You’ve done a great job oc’ing that rig. Well my work is still cut out for me with my x2 4400. I’ll try a little more volts; it’s not going to help the heat though. I’ve also been thinking about removing the HIS. My concern with that is seating the Zalman7000 HSF. Just concerns me but I’ll get though it.

[Pyr0]

thanks tasr

one thing i forgot to mention is that when i switched to watercooling, i found i needed slightly less voltage to reach the same clocks

SLI-D 2750 @ 1.575v with air

SLI-D 2750 @ 1.540v with water

Venus 2750 @ 1.568v with water

 

i think the venus needs a little more voltage because the older lanparty boards overvolt slightly when under load, but i could be wrong

also, my memory needs approx 0.10v less in the venus, 2.7+0.3 (2.76 read in bios) on the sli-d and 2.66 (2.64 read in bios) on the venus

Some 4400+ just don't do 11 * 250 (like mine) i can get into windows with it, run 3Dmark 05 and 06 with it, but both Prime and Super PI32 crap out immediately

 

It's not a temp problem since Prime also doesn't want to do 1 core a time and it happens immediately (not enought time to ramp up the heat)

Idle temps are 34c

Anyone running these G.Skill Extreme Series 2GB kit (2 x 1GB) Model # F1-4000USU2-2GBHZ on a Ultra-D with an A64 x2 4400?
