Overclocking my A64 help pls

[balilu]

ok my cpu was overclocked to 2.15ghz and all the time time i overclocked more my ram was giving errors. and im sure that the ram can't go higher because it's a cheap ram which i bought and which i have to stay with for quite along time . anyway i decided that maybe i should try use a different memory:cpu ratio to overclock my cpu more whilst keeping the ram stable.

my current overclocking so far is:

Ratio 5:6 ( mem:cpu )

Mem: 186mhz ( 186*2 =372mhz effectivley ) @ 2.6v

CPU: 2.24ghz ( 236*9.5 ) @ 1.8v

mem timings are: 8-3-3-3

when i try increasing the cpu more it starts giving errors so i can't increase the fsb more so at least the ram would achieve a 200mhz clock ( 200*2=400 ). i also tried decreasing the multiplier but once i get beyond 240 fsb it starts giving me errors ( maybe it's the bios. gonna go and update it ). i need help to at least to make the ram run @ 400mhz ( 200*2 )

Before this overclock:

Ratio 1:1 ( mem:cpu )

mem: 215mhz ( 215*2=430mhz effectivley ) @ 2.6v

CPU: 2.15ghz ( 215*10 ) @ 1.6v

mem timings were: 8-3-3-3

i tried increasing mem voltage and loosening the timings before changing the cpu ratio so i could achieve i higher overclock but still no go. my ram is really keeping me behind ( too bad i have no money )

altough cpu is running @ 1.8v temps went down instead of higher and i arleady had this kinda strang thing and maybe it's because my cpu is a downgraded cpu. temps are 28 idle ( before: 35 ) and load are 37 ( before: 42 )

any help appreciated. i wanna get the best out of my rig.

EDIT: does it have anything to do with maybe the sata ports aren't locked?

changed the hdd from sata port 1 to sata port 3 and reached:

Ratio 5:6 ( mem:cpu )

Mem: 200mhz ( 200*2 =400mhz effectivley ) @ 2.6v

CPU: 2.28ghz ( 240*9.5 ) @ 1.8v

mem timings are: 8-3-3-3

EDIT: my bios in the text says 1.8v but according to cpuz and speedfan it's 1.7v and i think this is an issue which i found to be in the neo2 and i guess it's in the neo1 aswell

 

[NickS]

1.7v is kinda high for a winnie.

 

[balilu]

it's a newcastle

I dont realy think that you can do that much with your OEM ram. I defently think thats the ram thats holding ya back.

You schould probably leave the Ratio on 1:1 because it sure is faster then 4:5 or something like this.

ok updated new bios to a modded one. placed sata drive to sata port 3 which i found that it's not locked. and reached i higher overclock:

Ratio 1:1 ( mem:cpu )

mem: 220mhz ( 220*2=440mhz effectivley ) @ 2.8v

CPU: 2.2ghz ( 220*10 ) @ 1.65v

mem timings were: 8-3-3-3

gonna try on a different ratio

wow mem timings ! 8-3-3-3.... wow thats high. nice.

erm, i dont know how far you are going to get with your RAM. is it non brand?

 

[balilu]

yeah it's unbranded. altough i reached ddr440 with it and passed memtest @ 8-3-3-3. which isn't that bad. il be trying using 5:6 ratio. will there be a bottle neck? and will it be much noticable?

 

[Dav0s]

your ram will almost definately be your bottle neck. try and pick up some cheap branded stuff like geil and you will see that it can run higher at better timings. you really want to be looking at a max of 2.5CAS for good performance. also running a divider will definately affect performance and although your clocks will be higher, it will prob perform better at 1:1. hope this helped.

10x altough i have to stay with this ram for now ( unless someone is willing to send me some money ) il try testing with better timings and im sure that they are stable at 2.5CAS so il try and enforce an test it. and about the ratio il use the 5:6 and see how high i can go and see if i get any performance improvement in benchmarks
