Arctic Cooler 64 Pro

[darkorb]

i got one of those in my rig right now with some AS5.

when i set it to full speed in the bios (not to increase speed once it hits 50, just go max) at 2.4ghz the highest i see it get to is 52

i tried setting it to speed up when it hits 50, and the highest i get is 54 (i turned intake/exhaust fans on low, i want my comp to be near silent)

Just wanted to know, are those high temps? 2.4ghz on a x2 3800+ Manchester i believe

let me know..

I got a 3800x2 Manchester on an Abit AV8 here, that`s just folding on both cores atm, running @ 2.5 for a few months now.

Under load it`s 49, fingering 50 every now and again. When I stop everything it drops to 38/39.

This is with a Scythe Ninja (using AS5), no fan control just always on.

Others will have to tell u if the Artic Cooler 64 is better/same/not as good as a Scythe.

 

[darkorb]

i would think the scythe is better

i really want to get to 2.6, so my CPU can be less of a bottleneck for my gpu

yet i have a few questions

240x10 with 333 mhz divider my ram is at ddr 400

with 266divider, what would my CPU have to be at for my ram to be at ddr 400?

Did you clean off the paste on the 64pro?

I'm using the paste that came on the 64pro and initially the temps were high, but after a week or so they dropped. I think it takes much long er to set in compared with other compounds.

You've got about 10° headroom there. 52 is fine.

For DDR400 (200mhz) on the ram you need 300mhz fsb on the cpu. on a 400:266 (200:133).

And remember too turn the HT multi down for 939 clocking!

i had my e6600 stable @ 3.7 on a scythe ninja full load @ 65

i could get 1.5 without a fan full load @ 70

 

[darkorb]

there is no option in my bios for the HT, and around 2k is where its supposed to be

sry Ham, i dont understand ur terminology

i wana get to 2.6 or 2.8, 260x10 and 280x10 (lets work on 2.6 first)

my ram is on 333 divider, and its at ddr 400 right now. so some how ddr 400 = 333 divider x 260 bus speed? i dont get how it works

 

[Ham]

Hyper Transport can be called loads of things. IIRC you have an Asus board? Most likely its called LDT Multi/setting.

As for a ram forget ddr speeds, its nothing more than a rating. To get the actual speed of the ram you just divide it by 2.

If your running 200x10 then on your 333(333=166mhzx2) divider you will be running 166mhz on the ram. So at 250x10 you will be running roughly 200mhz on the ram. Too achieve 200mhz on the memory on a 266(133mhzx2) divider you need 300x10.

Ofcorse you dont need 300x10, you could use 300x9 (2.7ghz)

Hope that helps.

 

[darkorb]

ohhhh

so 300x9 with 266 divider i will get 200mhz out of my ram?

i hope i can hit 2.7 without raising the voltage too high

so you said 200x10 with 333 divider my ram is at 166

and at 250x10 with 333 divider ram will be at 200? but 200-166 is 34mhz and 250-200 is 50mhz.

see where im coming from? im not saying your wrong or anything nono, im just trying to grasp this concept by the horns so id ont have to bother you guys no more:worship:

 

[Ham]

The numbers were rough from memory.

250x10 on a 333(166mhz) divider comes out at 208mhz on the ram.

200/166 = 1.2

250/1.2= 208mhz Or DDR416

The divider names (400, 333, 266 and 200) are taken from the ratio of stock cpu FSB too actual ram speed, then x 2 (for ddr).

Hope that makes sence...

 

[darkorb]

ohhhi c

so i dont no if my board can handle the 300 bus speed

i c i c thanks alot!! reped

so what are some good settings for 2.6ghz and 2.8ghz without taking ram higher than stock (ideally being at 200mhz)

i tried myself with the way you said, but i was falling at 166mhz somehow

280/166 = 1.686

280/1.686 = 166mhz
