XP 1700+ Tbred A, Overclocking!! Help Needed!!

[vikash4900]

Hello Friends,

I have the following hardware:

XP 1700+ Tbred "A" OEM
CoolerMaster DP5-6I31C Cooler (ALL Aluminium)
Jetway KT333 Mobo
Kingston 512MB PC2100 DDR Ram (2x256)
40gb Seagate Barracuda 4 7200rpm
ATI Radeon 8500LE 64mb
Onboard Audio
300w Power Supply
Full tower ATX Case with 2x80mm exhaust and 1x80mm intake fan.


I have tried almost every thing, but i am unable to get the cpu to work properly over 1750mhz.

the highest frequencies that worked stably are :

9.0 x 194fsb x 194ram = 1746 mhz
10.0 x 173fsb x 173ram = 1730 mhz
10.5 x 166fsb x 166ram = 1743 mhz
11.0 x 158fsb x 158ram = 1738 mhz
11.5 x 151fsb x 151ram = 1736 mhz
12.0 x 145fsb x 179ram = 1740 mhz
12.5 x 139fsb x 172ram = 1737 mhz

With the above results, it is clear that neither the board nor the ram are the limiting factor.

all these results i got with the vcore : 1.625v and Vdimm : 2.7v.

Increasing the voltages beyond these does not help at all....i've tried vcore upto 1.8v....

I've got the highest 3D Mark 2001 Result with 9.0x194fsbx194ram:

The Default benchmark gave a result of 8551 3D Marks.


Where am i getting stuck? why can't i cross this 1750mhz barrier? Are my 3dmark scores ok?

Please help me. I want to be able to reach 1.9ghz like others have done....

i think that it's the RAM
PC2100 is rated to 266mhz
but when you push it to 194mhz(x2)=386MHz i think it gets unstable
try to find for the CPU:memory ratio and set it to 1:1
then i think that you will see a better overclock

I dont think its the ram....coz with multiplier 9.0, the fsb and memory can work stable even at 194mhz.........so, when i raise the multiplier to say 12.0....and lower the fsb considerably, even then the highest i can reach is 145mhz....

i dont think its the ram or the mobo.......?!?

what do u think of the 3D mark scores though?
