At 300MHz HTT, I can do SuperPi 1M and 2M stable.... but cannot do 4M and higher.

Do I need more voltage on the CPU? It is already 1.3V * 136%. Is it because of the memory controller sucky? It's kinda weird coz most Palermo out there usually runs 2.4-2.5ghz speed with 1.6V or less.

Or could it be because of high temperature that it produces error during stress test? I'm only running on stock AMD aluminium heatsink... haha Still waiting for my XP-90 which is coming in a few days.

I already run RAM/FSB divider at 2/3 so that my RAM runs at 200mhz. RAM is set at 2-2-2-5 with 2.6V (Memtest stable for hours).

CPU : Sempron 2800+ Palermo DH8-D0
Stepping : LBBID 0514CPMW
CPU VID : 1.3V * 136%
HTT : 300MHz
Multi : 8x
LDT : Auto
RAM : 200mhz, 2-2-2-5-1T @ 2.6V
AGP : 66MHz, 1.5V
Chipset : 1.6V
(Every else is set at default)

sempron a ar.. burned in at 1.875 and then after 1 week can use 1.8v

wah wah !! how u burn-in ? mind tell us ?

Run it hot hot on stock cooler ~58-60C folding 24/7

well stepping...how to see?
cpu-z?but my cpu-z cant recognize it..i use older bios
a7n8x deluxe uber 1007 bios coz i see som ppl say it got more option
sommmore no influence oso...jus cannot run super pi argh
i think the last method to see is take out the heatsink to see?
well another question...how high can set?anybody tried?
i dun dare to set at 1.75V scare burn

to see the stepping, u have to take off the heatsink... no other choice.

Topic merged.


Refering to post 1102,

Soulfly, I guess it's because of the high temp. 54 degrees is by all means not a desirable temp. If you could get below 45, I think this chip might fly.

Orite.. got that.

Received my XP-90 already... but currently no high cfm fan to play around with

Looks like a bit overvolt. Default Vcore for Sempron is 1.4V

Anyway.... your E6 can do prime stable at that speed?

newbie here.. how u guys OC?? juz increase the FSB enough?? in the bios??

AMD Sempron 2800+ 1600Mhz s754
Multiplier x 8
FSB 200Mhz

Default:-
200Mhz x 8 = 1600Mhz

OC:-
300Mhz x 8 = 2400Mhz


if using stock CPU fan n stock PSU.
wat is the temperature??
can get burn??
can it damages other components??

stock psu is dangerous, can damage the mobo or hdd, or other component.

stock cpu fan is not really dangerous... i'm using it to OC at 300*8 ... max temp is no more than 54'C with normal room temperature at full load. it all depends on the cpu. sempron k8 usually runs at a bit lower temp compare to athlon64 at the same speed, bcoz of smaller cache.

I think up to 2.65ghz is stable to prime under default. I tried to prime 10minute and it pass. Tonite gonna prime till tmr n post my result again. Btw i feel my abit NF8 mobo got good capasitor. My icute psu giving me good rail compare to my other mobo. It giving me constant +5v and +12v . So i gonna use icute for this rig n purepower for 2ndary rig.

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.....

kekekeke

seems like more and more people is joining the Sempron K8 ranking

my OC result..
Venice 3000+
2.808 @ 1.52 V
Cooling type : air : xp-90c + Ventec Tornado

What a 'big' image. I can barely see your score.

sorry

next time i will post "kecik-kecik"..

attention DFI NF4 DAGF / INFINITY users....

the Beta BIOS dated 11/8/2005 is now official.....

Download = http://www.dfi.com.tw/Upload/BIOS/CK84D811.zip

Date = 11/8/2005

Desciption =

1. fix IDE channel 2 access mode issue.remove CPU temp (outside) item.
2. Change DRAM configuration item value.
3. CPU voltage 1.55~1.85 one step 250mv.
4. add chipset fan control 90%, 70% and 60%

found the place they sold the week 25 E6 venice.. will update you guys soon

In aussie or here? I can't seem to find any, the nearest i get is week 29.
