when you raise your HTT.. you need to set your LDT multiplier to x4 or x3 appropriately according to your HTT..

HTT x LDT multiplier can't exceed 1000.. well it can.. but there's a limit on how far you can go past 1000.. the best way is to keep it under 1000..

as for ram timings.. it depends on which ram you are using..

there's 2 multiplier..

CPU multiplier

which is 200 x "10" for your particular CPU

and LDT which is 200 x "5" = 1000 for every athlon64 system

i can't remember what it's called in abit's bios.. but there should be one stating something like 1x 2x 3x 4x 5x or 200 400 600 800 1000

as for your ram.. run it at a divider.. in your dram configuration page.. set it to run at DDR333 / 166 to eliminate your ram as the factor that's holding back your CPU..

don't bump your voltage unless u can't go any higher

there's definitely one there

find one that gives u only 5 options

1x
2x
3x
4x
5x

or

200
400
600
800
1000

if you don't set it to x4 don't expet it to go higher than ~ 220

there's actually no gain if you go past 1000

just keep it below 1000 and it'll be fine

up to 250 set x4
past 250 set to x3

and so on

don't use a .5 multiplier for your CPU .. it manipulates your ram to give you that clock..

if you use .5 your ram will be clocked lower..

use a divider.. run until u hit a wall then raise your voltage.. then keep going.. hit a wall then raise voltage.. and so on..

it's safe to go until about 1.6 i guess if the temps are below 55

test one by one.. don't try to overclock both together.. u'll end up wasting more time..

did you set your ram to run at DDR333 / 166 divider?

for abit the temps usually is about 5-8c lower.. so add about 5-8 back to the reading and it should be right

if you don't set your ram will run async to your HTT.. and if you ram can't take it your system won't take it as a whole.. running a divider makes sure that you are not RAM limited when overclocking your CPU..

sse3 is a set of instructions used in programs.. i think it was first used on intel CPUs.. and now it's on Athlon64 as well.. i think winchesters are the first one to have? (correct me if i'm wrong)

i'm not familiar with SSE3.. maybe someone else can enlighten you on it smile.gif

actually there's no performance difference running it below 1k.. so don't worry too much if it's under.. i use x3 all the time..

if your bios have the option to raise the LDT and chipset voltage.. do so.. it helps improve stability..

try a 133 divider if you wish to go higher.. always keep your ram at or below spec when you're testing your CPU..
