humm... great guide, but! im having problems i dont seem to have a PCI lock in my BIOS and when i set my front side bus to manual i only have the option of 200, My board is ASUS A8N-VM CSM

anyhelp guys

edit: and ive got AMD A64 3200+, 512mb of corsair value select ram pc3200

Have you tried clockgen? It should not only let you increase the HT speed (the 'FSB'), but you should also be able to see if your PCI bus speed is locked (it should go up/down as you change the HT frequency).

yes i have and the pci bus speed does move on the second slider not top one, although still can'tOC in bios and clockgen has to be redone everytime you restart

cheerz for the guide helped me get my amd athlon newcastle 3000+ oced a bit. was running at 2000 mhz now running at 2390mhz only thing now is i cant get it to run past 2390 its either my cheap ram or my cooler as i have the same one i got with this cpu i think cheerz

Sorry to sound like a complete noob,but does anybody know where in the bios I can enable PCI lock?I have an ASUS A8N SLI Deluxe mobo

Sorry for the n00b question but to find your maximum FSB why do you need to lower the multiplier, why cant you just up the FSB?

thanks

By lowering your multiplier and upping your fsb (htt) you are effectively removing the cpu from the equation. You will be literally underclocking your cpu.

You are trying to find the max stable fsb that your mobo will be happy with.

Thanks for your reply.

I'm still confused to be honest, so to get the best overclock you want to up the FSB as much as possible to help the speed of data transfer. so it's not all about the actual CPU clock speed then?

The only way to overclock, is to up the fsb.

The reason you lower the multi and see what the board can do fsb wise is so you know what is going out first.

E.G. If itested my fsb on my memory, and i got it to 290fsb, and then i put the cpu to normal and overclocked it, and the computer crashed at 265fsb, i would know it was the cpu that was holding me back, because i know 100% that the memory can run at 290fsb, as i tested it.

ah right now i get it, thanks!

just a small note to add to this
peternewell made a remark back on page 3 at the very end of it, having lots of hard disks is infact a bad thing for two reasons.
first reason, obviously its heat
second reason is that they slow 3d performace down
i have seen a rise of around a 1000 3d mark points just from removing two hard disks that were using pata connections,
i have only wha bt i need in my system, 2 raptors in raid 0 and one single 300gb sata2 disk for installing games on.

it makes a huge difference, i feel the difference after removing the 2 hdd's
if u like two have lots of data on hard disk, i advise using NAS as external usb disk cause a simular slow down effect.

just my own expirance, let me know if its any help

[finlay666uk]

Well a Raid 1+0 is actually better as it is read of two disks at the same time, and density of the disks matters a lot in terms of performance as does defragging them well and often

and the hard disks on a PATA connection must have been pretty poor as I see no notable improvement in removing my SATA1 maxtor hard drives which are purely for data storage as well as my media

Anyone know how I could overclock a e6400? I think that if I increase the FSB (dunno how) I can get to overclock higher than 3Ghz. I would be using a freezer 7 pro as the HSF

FSB speed is mostly controlled in your bios (press escape or delete during post screen usually), you then look for the cpu frequencies and /ram and each time you make a change you must hit f10, save and exit and restart your system, then test in windows, go back to bios(restart) and repeat.

or if you are lucky you might have windows driven software that will help you overclock, like ntune for the NF4 chipsets. not all boards have this but there are also third party programs which do roughly the same thing.look online..

if i were you though I wouldnt go changing anything until you know what the principals of overclocking are and a good idea of whats needed to successfully overclock without blowing you stuff up. this guide is a great starting point

[parkes53]

Phew...I didnt blow my pc up

[krsvz]

Thanks alanore.Much appreciated. especialy as i know nothing about oc'ing and im new to all this computing malarky. Keep up the most excellent work.

Mon the biffy!!!
