As the above mentioned, what is the maximum voltage or timing that i can try to push without fyring them? Thanks in advance, new in OC and would like to try.

BTW i'm using Gigabyte GA-8I915G Duo, not sure how far i can go. Currently running on a P4 640 Prescott 3.2. Thanks for advice.

Check your RAM's box ... Higher than what voltage void warranty?

I use value RAM all put 2.1v also no problem.. I guess performance 2.2v consider ok..

Some info i got of the intel website about my proc.

I think HyperX can clock higher without adjusting vdimm .. Try clock higher first lar..
IF PC restart or hang.. Then increase 0.1v.. What is the current vdimm? 1.80v?

Problem is, i dunno how to clock higher, using bios or using software? lolz.. i'm newbie, bought a performance ram but dunno how to utilise. I'm only running at 333 now, very very sad. lolz..

Oh... Haha.. I don't know much about PEntium 4 .. Long time din use already..

Want increase voltage must go through BIOS ..

Download some overclock tools first :-
- CPU-z
- Everest
- ClockGen
- Memset
- Prime95
- Orthos

What else ?

Which 1 should i be using to tweak my RAM clock?? lolz..

All also must use ..

Everest to monitor everything..
Clockgen to adjust ur clockspeed ...
Memset to adjust the timing..
Prime95/Orthos to do stressing..
Supermod PI to check if ur RAM stable..

Open Everest, Clockgen and memset ..
Then open prime95 or orthos .. Run the CPU & RAM stress..
Watch the Everest's table .. Wait till CPU Utilization & RAM Utilization at 100%..
Use Clockgen to increase the clockspeed by 3 or 5 whichever u like but not so much..
IF PC hang or restart .. then u need to add vcore, vdimm or change timing..
Long way to go man..

anything above 2.2V is consider risking
