help plz in my overclock

[four4two]

im new to overclocking etc and im trying to squeeze the best outta my kit.

heres what ive got so far

ECS KN1 SLi Lite mobo
AMD 3700+ san diego SKT 939
Akasa evo air cooler
JeanTech Phong case
4 x 512mb ddr 3200
xpertvision 7600GT ( running @ 651 and 1578 with coolbits )
200gb samsung spin point
120gb maxtor
60GB maxtor

using systool ive managed to move the fsb upto 226.29 and the mem upto 177.80 using standard voltages. the temp ( according to everst is stable at 35c )

can some one tech me how to decipher the mem settings and increase performance even more ie voltage settings, CAS AND RAS TIMINGS.

CPU SETTINGS FROM SYSTOOL

MEM SETTINGS FROM SYSTOOL

CPU-z id

any more info needed just post and ill show what ive got

thx folks

Not too sure about fiddling with the memory timings, they're probably already set at their rated speeds & if it's only value RAM, you might not be able to tighten the timings up that much (if at all) anyway.

My two words of advice however would be to reduce the HTT multiplier to 3, as the HTT speed should be as close to 1000MHz as possible. Don't worry too much if it's lower though, as it won't have any affect on performance. Also make sure that you lock the PCI-E bus to 100MHz else you run the risk of buggering up your windows install.

EDIT: Just saw that you're using 4 sticks of RAM, this is a known limiting factor in terms of overclocking and I'm pretty sure that the RAM will default to CAS 2.5 and a 166 divider.

Yeah, 4 sticks is too many. I have 2x512 in dual channel.

I dropped the CAS to 2 or 2.5 whatever is the lowest your ram will go at a reasonable speed and saw how high I could get the HTT

Write down this figure. this is as fast as your mem will go at the CAS chosen.use MEMtest

You can now increase the VDIMM but I only did this becuase mine was rated up to a high voltage whilst still being on warrenty.

CAS latency is very important for us A64 users, lower the better.

Being on a divider hardly effects us.


NEXT...
Put a low divider on, something like 2:3.

And see how high you can raise the HTT. Decrease the HT multiplier so that the HTT*HT is no more than 1000MHz.

Now you have a figure which is how fast either your motherboard or A64 will go. You can do PRIME95..

You now have the option of increasing the Voltage of the CPU or the chipset voltage.

With this value and the value of how fast the RAM will run you can work out the best divider for you.
