using asus k8n
latest result from mine
i found out that setting the ram clock of DDR400 to DDR333 in bios doesnt affect anything since im overclocking everything..
using sempron 256 k 2800+ 64 which is 1600 MHZ stock which memory running at 201MHZ/8
Memory running at CL 2.5 3/3/6/11/16
DDR running at 400 which is 201MHZ which is same with the above 201/8
HT set to 4 which is 4*200 =800 Bus
running 270 FSB * 8 = OC tuill 2160 MHZ
Memory running 216 MHZ/10
memory running at CL 2.0 3/3/5/10/16
set bios DDR runnng at 333 but....
HT set to 3 which run at this 216MHZ*3=810 Bus
overall 35 % increase from 1600 mhz to 2160 MHZ.
this is the best i get so far
never touch the Vcore and Vdimm..i leave it to auto or default.
memory speed i also set to auto.

QUOTE(ahpaul82 @ Aug 28 2005, 09:47 AM) HERE, they able do 350HTT  , but vcore...  Using DFI NF4-4X mobo.  (SDA2500AI03BX LBBWE 0529EPCW Q382909G53101)
(SDA2500AI03BX LBBWE 0528BPBW Z727669G51962)they said this two stepping can easily hit 300HTT. i believe they only running the HT X 2..not X3 or X4 they only getting 350.4*2 =700.8..i think it's impossible to get X3 HT which is 1051.2 bus. AMD sempron running 800 Bus... and they already set higher voltage |

wah wah ..latest news..
i think im lucky ..i dont know what is my revision model
but mine is E6 sempron 64 2800+
update my bios asus K8n 1008...
i dont OC..but jz wanna try out
295 Mhz X 8 = 2360 Mhz 2.36 gig from 1.6 gig = 760 mhz increase = 47.5 % increase after o/c
HT set to 3,using ddr 333 set from ddr 300....
so memory instead of 200 mhz..running at 295 Mhz...
Ht X 3 = 295* 3 =885 instead of stock 800 mhz bus..
running stable....
Vdimm stock.....Vcore also stock....AGP clock also stock..all running stock
i did set to 300 getting 2.4 gig from 1.6 gig....can boot.....windows got registry error.....so i set till 295 never bother 296 till 299...
can see windows performance increase very dramatically...
yahoo
hopefully asus come up with new bios which i can set my vcore,and v dimm manually.....and the fsb i can set till 350.....

QUOTE(Cyclone87 @ Sep 4 2005, 06:17 PM) Oh ya...i forget something. I see u guys hardly break 300HTT mayb becoz of the pci/agp lock thingy. Some mobo came with Pci lock, but SATA Pci clock wasnt lock. If so u will end up sumwhere below 270HTT. My S64 was running under no CDrom and floopy on board. My OS is in my HDD, and i juz install the driver when i plug on my S64. Btw for me, with 2800+ ,my HTT is max at 345 and HTT Ratio is 3 which make it 1035mhz. If i running on a 2500+ sempron with 7x multiplier i can hit around 390-400 HTT with ratio 2x but vcore around 1.7v. I gonna go shop for 3100+ few more days. how u set vcore?in the bios can set ar? mine asus cannot set ler |

QUOTE(Cyclone87 @ Sep 4 2005, 06:58 PM) I hit 339HTT without vcore adjustment. Higher den dat i need to up abit . I will try up my HTT voltage n nf3 voltage to max n c how high i can go. wei i want to ask u something ur fsb:dram is 1:1? how come mine is cpu/10? you see right...my asus mobo max fsb 300 only so i juzt set the HT from 4 to 3...set the ddr ram from 400 to 333 then the timing all auto..... then i manually set the fsb to 295... then i got 2.36 gig is there other way? r u using good ram? mine is geil with blue sink |

QUOTE(sidewinderz @ Sep 4 2005, 10:08 PM) lolz...i dun think so la..cause processor OC capability varies between processors..even processors with the same stepping might not haf equal performance... my processor max out at 292x8.0 but if i go 289x8.0, i gotta use 133 devider  har..mine is C version ar..then low grade wan lor..hope i got A grade mine max out at 295 if i set it to 300X8 windows 98se got registry error..consider max out already? check this out... http://labs.zol.com.cn/2005/0408/162519.shtmlamd 2800+ OC on par with P4 3.4E and AMD64 3400+ page 9 till 12..dunno read chinese..but can understand the chart mah.. |

ram running at 236 mhz...
wish i had a abit mobo
