When i got this well it was on a budget so thought i would sacrifice on the motherboard. Later only i realise the mistake of buying a 800mhz ddr2 for
Amd X2 4200 as at stock i only get 367 and not 400mhz. So i contacted kingston and they told me well i can still set the timings at 4-4-4-12 at 2.0v
at that speed.

So i clocked the FSB at 212mhz and actually can push it to 213mhz via easy tune 5 with the hope of not changing the mem divider in the bios (no option to change in the bios anyway )so that i could get as close to 400mhz. Comp hangs at FSB 214.
Suspect...HT Link which at 1062,7 at 212 and around 1070 at 213.
All Vcore was at 1.35v
Is there any way to increase my FSB as much as possible either till my Ram runs around 400mhz. So far CPU temp has not increased at all.
I tried reducing my HT link to 4x and then changing my ddr2 to 667 so i can go higher FSB...nope failed at 215mhz. So then i thought keep the Ram at 800 and change the multiplier at 10x and HT link at 4x...again nope failed at 213mhz...

Any Solution..

I am noob to this so please help me..TY

There should be an option to change the memory divider in accordance with the FSB. You're currently running at 1:1, but there should be other options such as 5:4, 4:5, etc.

If this is available, you can try upping the FSB with a 5:4 divider, and keeping your multiplier at 10x. This would give you the ability to go 250 on the FSB, keeping your memory at 200, and 2.5GHz on the CPU. Leaving it at the default of 11x would result in 2.75GHz...you get the idea.

Without these types of BIOS options, I'd say your out of luck, unfortunately. You'll have to look around as I'm not familiar with that board.

Hmmm so that when u mean divider does that means i change my DDR2800 to DDR2667??

1.Is the problem now my HT Link is at the treshold??
Y cant i go above 213 FSB???

Now i have another problem i cant run 212 FSB stable so had to go down to 210 FSB via bios. HT Link is running at 1053.5 and Mem is at 386.3

2.After reducing the ht link multiplier ro 4x, y Doesnt it work??
Mem is not even above 400.

3.How to know how much vcore volts i need to increase??

 

[cstkl1]

ok I tried 230FSB 1.4v and i set the DDR2 at 667mhz running at 5-5-5-15
at Ht link 4x and CPU multiplier at 11x

It was running for awhile and then it crashed.

Where did i go wrong??

Is it the ram timings???

the Ram was running at 700 plus so still hasnt hit the 800mhz that i was hoping for

temp increased due to the increase in Vcore. Actually not even sure whether i should have increased it to 1.4v

 

[cstkl1]

Ok i tried with the experiment that u meant the memory divider is the frequency thingy is the same for ram.

I reduced my mem frequency to the lowest and left the timing at 5-5-5-16 which was on auto.

Then i changed my Ht-link to 4 and left the cpu multiplier at 11

I managed to change my fsb to 230 at 1.42v ( I upped it till there was no problems in starting windows and also till there was no fluctuations)

Question is 1.42v too high??

Temp at no OC is 38C at idle and now it is at 40C( changed the upper and lower limit of the smart fan)

I noticed that during overclocking in the beginning above that theres a limit i can do go for my RAm bios reported speed

Meaning that 213*11/5.5= 426 is the max eventhough real mhz or the ram is at 213*11/6=390.5mhz

that means even i overclock my ram at 667mhz to 800mhz my motherboard has a limit to it???
so max i can get from this mobo is at 390.5??real and bios report at 428mhz??

did a stability test via ntune for oc setting above...was fine but after having the cpu stress

noticed flctuation in the vcore that it was 1.47v which means that i have to up the vcore to 1.45v but problem>>

Temp at full load was at 56c..isnt that kindda hot??
Ambient temp is at around 32C
Idle Temp is at 40C

is it worth to keep the comp at that setting for mere 16percent difference??

Question .

If i reduce the multipliers does that mean i can reduce the vcore??

Weird thing
Every time i look up the web ppl say theres no point in overclocking the PCIE

ok so at my setting of 230*11=2530 PC6400ddr@ 730mhz 4-4-4-12 HT link at 920mhz
MsI Nvidia 7900gto 695/800

I wanted to see the benchmark of this using 3d mark
the first two graphic test the movement was jerky...

Hmmm so i lowered my FSB back to 200 and then restarted it back....it was fine

So i Made my FSB back to 230 and now i clocked my pcie step up till the movement was ok at 110mhz

so how come this had a difference??
Bandwidth was not enough???
