The San Diego OC DISCUSSION Thread

Me and a friend of mine have bought an 3700+ 939 kab1e 0626fpmw. This is stable at 3150 mhz with 1.45v on air but we are not able to let it do 3180 mhz even with 1.6v maybe it's the mobo ( asus a8n sli deluxe bios 1013) or the 350watt bequite psu. And for a reason unknown to us it is not able to boot with tccd at all.

Where you bought that CPU?
Asus is bad motherboard for A64 overclocking, so does 350w psu.

In germany i know this store owner and he lets me pick out the one's with nice steppings .
i know asus a8n sli is bad for oc'ing a64 bit i got it for 20 euro's. psu is going to be changed to 520W bequite ( i have it laying around here.... somewhere)
You think this board can be voltmodded to like uhm 1.8v or atleast fix the droop. If this can be done we can bench in a cooling ( where meat is stored and stuff, it is capable of holding the temp on -25 ) the manager there has agreed to put in right in front one of the huge blowers.

having problems over coming 2805hz with my 3700+ and making it PI stable.

I've tried changing the multi, and can get better HTT ... but still seem to hit a wall around the same overall chip frequency. running 1.5volts atm, have had it up to 1.7volts to try and get this suckers to go higher, have lowered the HT etc .. but still not having much luck.

cooling is ZALMAN CNPS 9500 ( and some crappy thermal paste ... will sort that out )

load temps 33/47

can anyone give me any advice ..??? or is this the end of my chip's performance increase ?

Hi, did u tried other dimms ? This could be the problem. If it´s not ur cpu is an their end.

I'm the same mate, only 255x11 (2805MHz) is my stable limit with prime running for a week using predominantly small FFT's.

I can't remember the stepping, but I can get 255x11, 280x11 and 330x10 stable. Using .5 multipliers is bad, apparently. 2.8GHz is good enough for me, although i'm tempted in getting a 4000+ SD to break 3GHz with that 12x multi.

[blade148]

tried other dimms, and had the HTT much higher and the ram was stable.

i have a strange stepping ...

KABCE 0542FPMW

and early one, so could well be the end of the road for my chip.

thanks foir the replys though, wanted to know if i was doing anythign wrong. ... !

I have a KABYE 0542 FPWM lying around (3700+) which does 3Ghz prime stable on 1.45v.

And, I've received a new toy yesterday:



The stepping of this 4000+ is KAB1E 0626 FPMW. Havent found it's max. overclock, but I'm pleased to see it does 3Ghz. Besides that, here's some TCCD fun:

Unfortunatly this RAM doesn't want to boot over 300Mhz on the sandy core, will have to tweak around again

[knopflerbruce]

I have an FX57 CABYE 0540MPMW here, anyone ever heard about it?

Can't find ANY info about it anywhere, lol. Just want to know if this could be a WR-stepping or if I should look for some other stepping instead
