Athlon 4000+ San Diego voltage

[Laurijan]

did you set your HTT link to 3x?

Yes i never was over 1000Mhz

 

[Laurijan]

So what speed is your ram actually running at at those clocks and what actual speed is your HTT?

My ram are never over the speks 400Mhz and the htt which i tryed to adhive was 250Mhz on a 12 times multi

 

[cdawall]

i doubt your system is killing you seeing how i pushed my chip up to 2.59ghz and a 1.82vcore on a 500watt

 

[Laurijan]

use an 11x multiplier, then use 275 fsb. That gives the best performance. then just increase ur fsb from there if its stable

I´ll try different bios versions cause the multi 11 htt 275 didnt work either

 

[trog100]

mine got to its 3.2 gig at default core voltage on a via chipset mobo and value ram.. i did use a zalman flower cooler but it still ran hot..

i ran it at a nice round 3 gig for about a year before it moved to its new owner who has carted it off to the Philippines where they still think it and its pretty cooler plus 1900xtx card is the bees knees..

What BIOS are you running at present ?


Also something to look into burning to ISO is TMODS bios medic...found here....

BTW have you tried dropping the multi to like 6-7 to see if the bus will even post any higher?

I run the offical latest bios from the dfi site and when i lower the multi to 7 and the ram divider to 100 and the ht multi to 3 while rising the bus speed to for example 250 prime95 workes flawless - so its not the bios or the mobo holding me back - also i got enough juice from the PSU and the memory is not the case because the same limit (233 bus) i reached with mushkin black level II ddr ram - it has to be a badly overclocking san diego i got.

i played with mine for ages difernt boards an 3.3ghz was max on all but i never went over 1.55v on good water cooler core temps wer never over 35c

im still wondering if my opty165 can take 1.7v cus it will do 3.2gh if it can

Is the stepping code CABGE?

I heard that CABGE sux.

But, I'm still with socket A.

 

[Laurijan]

Cpu-z says stepping 2 and revision dh-e6 it must be that cabge crap because no other component can be the cause for this low overclock

 

[curt]

youled be suprised

it could be your ram settings

my new dfi expert board is vary picky with ram settings

like if i do 366fsb i can do 2.9gh at 8.0x but if i put it to 8.5x it wont boot

but if im running my normal 338fbs i can run 3,ghz or 3.1gh all day

like last night 1 setting needed 3.22v on my ddr1 ram to be stablerite now my ram is useing 2.8v

Im not tryin to be funny about this but if you have another CPU ,Id love to give it a go as I have the exact mobo in my 2nd rig. There are a few guys here that I think will assure you I am a good stand up guy and not trying to steal your chip.

I say realistically I could take that chip and OC it to its max and take screenies of my bios options and settings.

Reason I say this is you would then know for sure if it is in fact the CPU or possibly the ram or Mobo.

Im not saying you need to be this trusting , but I am a very good DFI clocker and have all the parts it takes to clock on a DFI well. If you plan to keep a 939 for a bit the week or so without the sandy could be well worth the time!

If you are reading those voltages out of the BIOS or any other software they are probably wrong.



I had to bring home a fluke meter to test my Antec, and make sure it was putting out the correct voltage. I also checked the VREGS for actual CPU output, but be careful when doing this as one slip while it is on and you have a toasted chip.


BIOS for me was .2v shy of true, and CPU-z and Everest kept reporting voltage fluctuations where there were none, I had to lap my HS more though, and this board didn't like the chip for some reason, I managed to get it stable at 2.9 and no more, but the guy it was sold to has it at 3.2Ghz stable. He has a DFI and more memory timing control.

Yeah, that's because 939 chips really don't like using half multis. Only the AM2 brisbanes can really use them.

Might it help to use 2T instead of 1T?

How many RAM sticks are you using?

 

[Laurijan]

2 Sticks of Valueram at 2.5-3-3-7 400Mhz usually while the didvider is 180 i achive a 396Mhz overclock of the CPU with them

 

[Darknova]

Ok you should be fine then. You only really need 2T if you have 4 sticks. The problem with DDR is that you can lose up to 40% performance going to 2T. Which isn't worth a few extra Mhz on the CPU.

Laurijan I have a San Diego (3700+) therefore voltages up to 1.55 are not dangerous.
It is recommended the CPU temperature keep up to 50-55 Celsius under full load.
My CPU is 23 months old and is still alive.
The Vcore is 1.47-1.52 Volts (depending on settings).
