link26 im as suprised as you are :Q
i was only hoping for the same temp from a quieter fan - but the alpha does work very very well. prolly cause its huge and very very heavy. i was previously using a thermaltake P4V S478 30cfm 37dba - also a very good cooler.

i dont know what the OEM is rated @.

BTW: i have the fan direction blowing down onto the cooler.

Thugsrook What brand of PSU did you get?

Two things I notice about my system that are limiting my system to go upto 160FSB+
I did the wire trick and everything is rock solid @ 150FSB, even setting vcore to 1.700v
First it is my memory, it would lock up and blue screen me @ 160MHz. I know it is my memory because when I used my friend's Samsung PC2700 it boot up fine with no lock ups...it even boot up at 166 @ 2-2-2-5 setting. I tried changing the memory setting to 2.5-3-3-6 ro 7, still no good...it's a little more stable...but still blue screened...I tested the Samsung PC2700 on a P4S333 (flashed w/ P4S533 BIOS) where FSB @ 100 w/ memory ratio 3:6 which = 200MHz = DDR400, but only at conservative memory setting 2.5-4-4-7, having really mess around with it.
Second, I notice my 12v line would drop to ~11.5v if I put the vcore @ 1.850 (max setting w/ wire trick) when under load.

So I am planning on getting new memory and new PSU. I just want to know what PSU is the best. I currently have a 420W PSU.

SupermanCK im glad you are figuring it all out

im using the Enermax 550W.
a 431W Enermax would be good to 2656mhz 166fsb, but not higher.

there is a TON of Kingmax PC2700 for sale in the FS/FT forum.
Kingmax aint the best out there, but it will run upto 400DDR.
...and by the way it looks in there, you should be able to pick it up extreamly cheap

youre doing good work there - keep it up

again i have not tweeked 1 setting on this board yet - everything is on default.
*vid card is a gf3ti500, 250x550, 27.50 drivers

3DMark2001SE 9519 Compare
Sandra Mem 2527 / 2417
Sandra CPU 5104 / 3332
Sandra Media 10763 / 13116

im gonna stop at 170fsb for now, and start testing for 12 hour stability.
ill keep this thread updated with my progress.

Impressive. Most impressive

 

[THUGSROOK]

Texmaster wow those GF4s are awesome

UPDATE
everything is 100% stable @ 2800mhz 175fsb 350DDR cas2/2/2
not 1 crash, hang, bsod, or slow down - awesome

vcore is set @ 1.775v and gives 1.820v, vmem is still 2.5v.
im using the 1.7v wire mod and NOT using the overvolt jumper.
turbo1 mode.

 

[SupermanCK]

Thugsrook so how much did you get the Enermax 550W PSU for?

 

[THUGSROOK]

it wasnt cheap - $155.
a 431W goes for $89

 

[SupermanCK]

Where did you get it from? Directron? Is it the new one with adjustable fan speed?

 

[THUGSROOK]

no - i got it from newegg.
it has the thermal fans - plenty quiet, plenty cool.

 

[Zainul]

Anyone have luck on MSI 645E MAX2-LRU + 1.8AGHz = 2.4GHz with default fan and voltage?

 

[Shimmishim]

have you sold that 431W enermax yet? PM Me thanks!

[boObYtRap]

Hey THUGSROOK... can u please post your memeory settings and ratios and all that. I have the same mobo.
Did u go for the "Turbo 1" in the BIOS.?

 

[THUGSROOK]

 

[SupermanCK]

Has anyone been able to find out what are the settting "normal", "turbo 1", and "turbo 2"?

 

[THUGSROOK]

for the moment i am using turbo1 mode.
im gonna do some more bios tweaking tho, so that may change.
i guess ill just give a full report on what i get outta the bios.

BTW: im using bios v1004.001. i didnt like the v1004.002 bios.

 

[THUGSROOK]

SupermanCK my guess is....

Normal = Normal PCI and AGP speeds
Turbo1 = 35PCI 70AGP lock
Turbo2 = 40PCI 80AGP lock

im gonna run more tests and keep you updated on what i learn. LMK if you find any info in other forums.

 

[zzzz]

Thugsrook, you should get a rdram based mobo and some PC1066 ram and unleash that beast of the cpu!
People have got the abit Th7-2 to about 180 fsb so the chipset is not a problem overclocking. You have to lower the ram multiplier to 3 so you will be ruuning at (175*3=525 )which is well within the PC1066 capability(533). + that board had pci/AGP lock as well as the fsb/pci ratios of 5:1, 6:1 wtc.

 

[THUGSROOK]

na, all i need is a memory ratio and that RDram will be dust

 

[link26]

Yes. you can stop overclocking now, thugsrook. We'll check back with you in one year. You are the Anandtech guinea pig. We are all too chicken to push the cpu up that high....

 

[THUGSROOK]

i dont blame you guys for being chicken
was getting nervous myself going above 1.8v.

hopefuly everyone found all this info and the 2 charts in main post useful.
LMK if there is any other info you guys need me to post.

 

[John]

One heck of an o/c, congrats.

 

[JTKGY]

Guys... i'm getting a mobo warning with vcore over 1.7v...
is this the limitation on the mobo+cpu that requires
the wire mod??

 

[THUGSROOK]

John thx

JTKGY thats a moboard thing.
in bios set "HALT ON = NO ERRORS".
if that dont work - "IGNORE" vcore voltage in bios.
the 1.7v wire mod would stop that too.

HTH
