3700 san diego overclocking

Dimension said:
I just built my first A64 rig yesterday

my 3700 san deago appears to be running hot. 40 oC idle and 50 ish at load

I am using a Scythe Ninja it does not get more than warm.. the CPU temp intermittently jumps every now and then between 30 and 50 when under load and 20 and 40 at idle
I'm not sure if that indicates that the reporting chip is faulty ?

I am using a DFI NF3 ultraD board, cos i bought a x800xtpe AGP at the begining of this year and i cant afford to replace it with a pci-e yet...

I have applied AS5 twice now, so im sure that is ok.

don't think your chip is fauilty, but might indicate your temp sensor on your mobo is a bit naff.

Don't kow your mobo. but the neo 2 's had the same problem til a bios change. might wanna check your mobo manufacture to see if there are any bios updates ... and more importantly .... IF they fix your prob. ( temps jumping. )

i didn't thik 50C was a problem for these chips, and considering your HS is fanless ...??? i'd say it was pretty good. ! :)

ok well i have a 3700 i am currently runnin at 236*11 so 2.6ghz HT5 its very stable gonna have a play in a moment see what we can get

HT5 :eek:
that's pretty good !

if you get any problems i'd first turn down to HT4
I'm sure you want to keep it at 1000
 
Just put a new 3700 in my new rig. The new 3700 i've got is amazing. Its doing 275 x 11 (3030mhz) at only 1.48v (9hrs prime stable - then i turned it off). Running superpi 1mb at 28s.
Will keep you posted as to what it does.
 
seem to of hit a wall at 2.7ghz no matter which multiplier ht width between 3-4 which either remains below 1000 im thinking of changing the HTT width but dont know what is best 16-16 8-16 16-8 ??

cheers blade148

Found a couple of beta bios's they have dropped my temps down by 7 oC. looks much better now.

I'm running 240x11=2660 and it keeps below 45 at full load now.. the only thing holding me back now is the cheap memory i am using. adata pc3200 2.5T :(

Not sure if it's worth spending much on DDR now, as the M" boards will be out next year and they use DDR2

The stepping of my 3700 san diego is KABCE 0542

My chip is the same stepping. At the moment its at 3.14ghz at 1.55v and its still going higher. This is the best chip i've ever had. Load temps are 37 degrees with a xp120 and a vantec stealth fan.
 
hi guys, im new here and i have a 3700/ mobo Lanparty SLI-DR/ 2gb Crucial Ballistix Tracer pc4000/ air cooled with Gigabyte 3D...
I tryed to make a over but the system rebooted...i tryed 10.5X240, but i leave other things on AUTO...Its to many things to setting!!!
What i have to leave on AUTO on DRAM and CPU, and what i have to change for this configuration? Since i read this post, i was happy because its about 3700...
sorry, but im newbie in over and i dont want explode my computer :D
can anyone help?
sorry for my English
Regards

you will need to set the Hyper transport (HT) multiplyer to 4 and you may need to put the ram on a divider also what voltage are your using
 
Mine is at 2.75GHz, Asus nForce4 Ultra SLI, 2GB OCZ Value RAM.

Stock heatsink and fan, running 52*C after 8 hours on Prime95.

ok, but should i change de voltages????
and wich settings should i keep in AUTO?
tks
 
To get to 2.6 mine took 1.525 but its now sitting at 2.8/1.65v

I can't get any more of a useful gain. Well, only if i went to stupid volts. I got scared at 1.72. lol. :D
 
Mine does 2.6 at stock vaults, no probs, stable as anything. Tested 2.8 ghz at 1.5v last night, seems stable in super pi 32m and passes the occt 30 min stress test. Testing stability using super pi 32m at 1.9ghz, hopefully all goes well. Will start priming next week. Load temps stay below 50 at all times, 45 average, stock cooling innit.

Currently running 2.75 here on stock volts on my temp mobo ECS nforce4-a939 hehehehehehee :D
My Abit AN8 Ultra went **** up.Awaiting replacement.
See it can be done on any mobo why pay extra anyway..

Can do 2.85 at stock but ram fails. not got around to doing all the tests yet on extra volts but i will.. :eek:

Mmmmm 3 gig..
 
Hmmm i have mine running at 2.85 at 1.45v but i have to run my ram at 166. even though i have just bought some corsair pc4000 it fails memtest at anything over 230mhz no matter the timings.. i'm convinced it's the crappy DFI nf3 motherboard, as their plagued with faults :(

I'm hitting 50 oC at full load with a Scythe Ninja with a 80mm nexus strapped to it.
 
Ive got mine prime stable at 2804MHz, thats with a FSB of 267 (10.5 multiplier) at 1.45V. Dropped the HTT to x3, and got the RAM on a 166 divider so its running at 215MHz@2-3-2-6.

If I keep my multi at x11, I can only get to 250MHz on the FSB (2750MHz), if I changed it to 251 or anything higher, Windows wont even load! I've tried it with up to 1.5V, messed around with the other settings, but it still wont boot... kinda weird:S
