QUOTE(-pWs- @ Dec 15 2007, 06:57 PM) I cannot check the fan rpm. How you check? HIS didnt give u the software for ur GC? mine is Asus. They gave i think,3 softwares. 1 for Video,1 for in-game gc setting and the other 1,is for the setting of the GC. like u can set the fan rpm,the core & memory clock  -pWs- From the software,i can set the fan rpm. dunno bout HIS brand though.. |

I think mostly dun have  -pWs- maybe u can try other 3rd party software? but i dunno what's the software since i havent tried one yet because i found that software given by Asus is more than what i need. so,change to Asus brand la bro...go sell ur HIS 3850..and grab Asus 3870! btw, im still waiting for anyone who have OCed their 3850 with stock cooler. wanna know the temp during full load and is there any big difference with stock core & mem clock...  |

QUOTE(hanny562 @ Dec 15 2007, 09:39 PM) yupz...about 63~66 degree C..quite cold.. hurrmm...quite ok the temp..not that hot since u are using the stock cooler..btw,is the temp above is during the full load? or during idle? EDIT: around 4-5C increased between idle and full load...so,what's the RPM of ur cooler fan? did u set it to 100% speed? im really interested to try it since i've done with my X2.

i have some doubt here about proc core voltage when OCing my GC.
If I wanna OC my gc, do i need to increase proc core voltage? let say my voltage now is 1.35v. if i OC my gc,will there be any instability issue due to my voltage? anyone can clear my doubt?  |

QUOTE(fesick @ Dec 16 2007, 02:35 AM) uish..my 3850 temp quite scary woo why not try to increase the cooler fan speed? my default fan speed is 40% (dunno the exact rpm as it only stated in percentage), the temp is around 50-52C when idle. i changed the speed to 60%, idle temp is around 44-45C. Will post some screenies tomorrow..btw,im using Asus and they've given a software so that i can change the fan speed. for other brand,i dunno. |

QUOTE(-pWs- @ Dec 16 2007, 11:19 PM) Ermm...hard to say here. Sometime will experience random restart. i think,its time for u to change to 1kW psu + 3870 series.. And when i load the 3850, 12v rail from 12.10v drop to 11.90.  Like this still ok, PSU keluar bunyi pula  -pWs- im still waiting for hanny562 to share his experience of OCing his 3850 before i OC mine..  |

QUOTE(egoiste @ Dec 18 2007, 06:26 PM) 3850 owner..is it really worth to buy this card? 3870 is out of my budget.. if u really have tight budget,then go for 3850. but i think there's one forumer selling 3870 at RM770. forgot the brand. FYI,i bought my Asus 3850 at that price! after 3 weeks, 3870 change the price to rm770. very sad... btw,3850 is worth the value for me + the Asus brand is really good... wanna buy mine? |

QUOTE(-pWs- @ Dec 18 2007, 10:30 PM) Wow...do u benchmark w 3DMark? i've benchmarked it with 3DMark06. Improved around 1000+ Want to see how much it improves -pWs-  before OC,the score is around 6k+. after OCed,score increased to 7k+. dunno whether its good enough or not but i certainly feels the different when play games like NFS & Crysis. @-pWs-, go laa OC ur card. then post ur ss here im still at kampung now.will post my ss once i go back KL.@MangKoK^ayon, yup,a very good temp & OC! as i said,the temp will be around 55-56C max when play games.if stress it,temp max is 68C. so,very good card indeed!

QUOTE(-pWs- @ Dec 19 2007, 02:58 AM) How come so low for your 3DMark06? yeaa...thats what im thinking ..but then,i think its my ram that limit the score. My card stock can go near 9k already -pWs- dun have any idea,but logically,my proc & mobo is good,so should be the ram that limits my gc...(correct me if im wrong) |

QUOTE(noobianz @ Dec 19 2007, 01:08 PM) IMHO and from my experience,an Athlon X2 4000+@stock will bottleneck my 8800GTS 320mb which only score around 7k in 3dmark06(now im using HD3870)...after i oc'ed my proc to 2.7ghz, my 3dmark06 score increase to 8k+ with SM2.0 and SM3.0 score increase alot..the same situation happens when i change my GC to 3870...from 2.1ghz to 2.7ghz give me around 10-15fps bonus in certain games such as company of heros my x2 4000+ is running at 2.5ghz already so i would say,current X2(even 6400+) proc will bottleneck any high end or top midrange graphic card which include 3870,8800GT and so on after i OC my card,the score increase around 1k+ i saw ur signature,u r using Corsair valueram too,rite? so,would u say that i need to push my proc more so that i can get at least 9k score for 3DMark06? i saw in review in the internet,3DMark06 score around 11k+ using stock core&memory clock!  *Image taken from xtremesystems.org forum. how did they do like that??
