3700 san diego overclocking

shortone · 11 Dec 2005 at 11:43

I am currently running at 2803 mhz
HT x 3
255.01 X 11
Using 166 divider Memory is 212mhz I am still unsure of how to do memory timings properly Ntune says is RAS 7 RCD 3 RP 3
Dimm Voltage 2.7v
Chipset Voltage 1.6v
Loaded Temp=41 Degrees Idle 36 Degrees

Shorty

mine's running as below. when i upgraded to 2gigs my overclock went out the window - i could do 245x11 with my vx. then i lowered the multi to 10 and bunged the htt to 260 (with dividers) which is pretty sweet with 2gigs. i might play and see if i can get it higher with some loser ram timings/maybe a little voltage bump to the mem and core.

what's everyone else getting with 2gs on their sd3700s?

AMD64 3700+ @ 2.75GHz, Patriot 2GB PC3200 2-3-2-5 192.8 MHz, POV 7800GTX

I can get 2-2-2-5 on the RAM If I sacrifice some MHz. Hopefully my Arctic Freezer will be here by the end of the week I can't stand the noise with the vcore at 1.55.

How long have ya been running ya 3700+ @ 1.55v... I think i need to increase my vcore more to reach 2.75Ghz... What load temps do you get on air, as i'm currently on stock cooling, but looking to go to an Arctic Cooler 64 Pro soon...

Just a day see my post above. Gonna bring it back down to 1.7 till I get the cooler just to keep the fan under control.

I'm now running at 3Ghz 273*11 @ 1.5v thats about as high as my mobo will let me go

Blimey! What tests have you done on it?

BS Dave · 12 Dec 2005 at 20:58

what stepping is that needmore?

dokko · 12 Dec 2005 at 21:15

I really need to keep an eye on this thread.

So only raising the volts is dangerous for frying the chip? Raising the other two setting is ok?

shortone · 12 Dec 2005 at 21:52

Ok been 24 hours now using Prime95 no errors
2803 mhz
HT x 3
255.01 X 11
Using 166 divider Memory is 212mhz
Ntune says is RAS 7 RCD 3 RP 3
Dimm Voltage 2.5v
Chipset Voltage 1.5
Loaded Temp=39 Degrees Idle 30 Degrees

Going to play again try to get it to 2.9

prime stable for 24hrs it was still going i just wanted to play doom3 which runs very smoothly i got a pcmark05 score of 4090 http://service.futuremark.com/compare?pcm05=202602 seems alittle low so i gonna try tweaking the settings alittle haven't done anything else yet

i don't know what stepping it is a let you know when i take it out to see how far i can push this opteron i recieved this morning

YooEntSinMeROYT · 13 Dec 2005 at 03:03

Had mine upto 290x11 under a Mach II GT when I was running 1 gig of RAM.

Upto 275x11 so far using 2 gig RAM with a 1:1 ratio Prime stable.

Gonna crank it up to 280 & see how the Ballistix fairs in my DFI SLI-DR

needmorespeed · 13 Dec 2005 at 12:13

The stepping of my 3700 san diego is KABCE 0542

DaMasha · 23 Dec 2005 at 09:56

Could you post some 3dmark 05' cpu scores for these setups please?

BS Dave · 23 Dec 2005 at 12:07

i've got a cabge is cabce and earlier run? as mine will only do 2.60 with 2 gigs

just read this thread and a lot of people are getting stuck at 270 mark on the asus boards. Toms hardware reviewed the asus a8n deluxe board and they got to 270 as well. Have tried loads of different things and cant push past 270.

Think mine stops somewhere in the 260s so I run 11x multi. Can't get my CPU past 2.75 on 1.55vcore.

I can have 2.7GHz on 1.475 vcore or get 50MHz more if I run it at 1.55. Does anyone thing upping the vcore to it's max for 50MHz is worth it?

My DFI doesn't like going over 274HTT either. Although i havent checked for a newer bios so that could help.

At the moment my san diego is at 2650/HTT265/MEM265.

Not bad with cack value ram.

Since changing to watercooling i am now at 2800MHz/HTT280/MEM254
Plus the temps have gone through the floor! Lol! CPU voltage is 1.62v, i tried getting up to 2900MHz but it didnt want to know and im too scared to raise the voltage especially around christmas!

hi ya all !
i signed up to this forum solely on the strength of THIS THREAD ! !

I've got a san diego 3700 + and have managed to O/c it to 2750ghz, on a standard HSF !

the only thing that's stopping me atm is my 6800gt GS ( if appears it doesn't like the 4 C increase in cpu heatsink .... and then freezes during 3dmark2001 )
am getting a better HS for my vga card and then hopfully will resume my Oc ' ing experiance !

think it's def. the best chip i've ever had for Oc'ing and i'm loving it !

Matt

P.s will post full rig spec. in sig. when i get time .

james_earl · 27 Dec 2005 at 20:36

are you sure your gfx can be responsible for the lock up. a small increase in the hsf temp is unlikely to play havoc in gfx stability its more likely that 3d01 triggers instability that other stress testing programs do not.
