QUOTE(phunkydude @ Mar 5 2005, 07:03 PM) below are front and back of my pcb... your RAM is 5nsi only found the same ic at the front of my pcb (circled with yellow) i can't find any of it at the back of my pcb..... hmm... bout the green " [ ] " that i draw... izzit the location that i need to use pencil to draw " [ ] " ? .... 2 side? or just one side.. and which side... and another thing, how to check the vgpu ? ... i didn't see any vgpu in my bios... got vcore lah..

A 9600xt is doing 500Mhz at 1.5V also... since its the same core, i think it should be the same.... Its not adviseable becoz i reckon the stock HSF is not so efficent in term if working outside stock value. The lifespan of the product might shorter due to the excessive heat. Maybe u can follow Dead_man and mod a AMD HSF on the core before ocing more. |

U see a big difference in 400Mhz and 500Mhz?? but 100Mhz difference in a core can be alot. maybe can attach some ram sink on the ram and clock more. wat is the brand of the ram btw?? |

he's talking about the vAGP option in the mainbaord bios. it rarely affects overclockability.

I tried the mod. For the core I got it running at 535 at 1.63v.
But..... i have no luck with the memory though. Accidently applied too much voltage for it. Now got those vertical line artifact all over the place. I think i fried my gc. Solutions? |

well, did you remove the graphtie line again? i once bumped up my voltage to 3v artifacts, removed the graphite line, and presto, it worked again.

I just got mine today, and i must say i am rather disappointed with this card. It seems cheaply made all round. The PCB has sharp edges which they did not bother to sand down and the stock heatsink screams CHEAPY. Doesn't even contact the memory chips properly.

The stock cooler is rated quite good compared to other brand in fact.... u shd check out other brand's stock HSF.Other brand dun even bother to cover the RAM with anything.... Cant really expect much from stock HSF. That cap they used is from sanyo... thats kinda good in fact. sharp edges.... dunno about that. I havent see a card with round edge thou.... U know of any?? Btw, im not a fanboy of this card... just posting my own opinion. Also, its probably not wise to get this card at the moment due to the 6600non pro series.... |

(i'd like to thank arj to moving this to essential reviews and guides)
btw, the coltage regulation ic has an input of 12v. my overclocking of core seems to be limited after setting the voltage over anything than 1.6v. i believe the core might not be getting enough current (not voltage, remember two diff things here). if i connect my psu 12v to the ic's 12v input will my core get mroe current? i'm askling mroe the absolute vmod pros or electronic experts here. would appreciate any info. here the ic datasheet: http://www.onsemi.com/pub/Collateral/NCP1571-D.PDF |
