Opteron shut down when overclocked

[avision]

What are your load temps ? Maybe you are exceeding the upper limits set under PC Health in the Bios. If so, increase ...

[ICON57]

setting your timings at 2.2.2.5. is not relaxed, that is tight! try to loosen them up to 2.5.3.3.6.

Thank you both for your answer, sorry for miss placing the thread.

No It can't be a temperature isue. I tryed both water (~35) and air (~45). And temperature went higher runing 1M and I didn't encounter problems.

I'll try but I hope it isn't that, a cpu which cannot handle 2-2-2-5 is trash...

And why would my 2 opteron be that crapy

 

EDIT: If my thread is there I have no chance to be answered by DFI staff isn't it ?

It may not be the opteron. It could be the memory.

lol. a cpu which cant handle 2-2-2-5 is trash....LMAO

and "relaxing" timings to 2-2-2-5...come on what kind of help do you expect with statements like that....

[HeskyR32]

if it did it with 2 diff opterons you have ram compatibility probs. not because of the latencies but simply cuz these opterons are fussy gits and they dont like your ram.

fussy about which divider used also.

 

good luck!

Thanks to stay cool, your answer doesn't help me at all.

 

Any cpu should andle 2225 timing. Memory are sold for those latencies and there should not be any compatibility isue on the side of AMD.

 

I shall say that I already tryed two sets of memory; old BH5 and new BH5.

Lots of people run BH5 with tight timing whith no isue on opteron.

 

I'm posting here because I think the problem is related to the setting of the board.

Anyway tomorow I'll try to relax timing to 2.5-3-3-8 and eventualy try another set of memory with micron chip, in that way it will quite diferent from BH5; which still the best memory according to me

 

EDIT: I tryed several memory divider, and most of my tried were with 1:1 divider

[avision]

I tryed to relax timing to 2.5-3-3-8 with BH5

I tryed with another type of chip which is not lowlatency (noname 2700)

 

same problem

 

help please!

Have you tryed adjusting your beta timings and what are your volts? I suspect it is the memory find an appropriate bios and try to work with it. I cant use any CAS other than 2 nothing else will boot into windoes whatever I try you might have the same strange mojo.

 

You can still get good overclockes with a divider and if your cas is 2 you can have good memory bandwith. I would try a 2:1 divider just to make sure it is your memory as is so common and go up on the FSB. I might suggest you fix the problem instead of complainging that it doesnt work right stock the opteron has the memory controller and it is not approved for the DFI. There are plenty of threads on getting BH5 running loosening the timings is not going to help in the least unless you are talking beta timings.

 

You might also need more volts on the CPU to keep up with the memory if it goes faster even if you dont overclock the CPU.

Try raising the read preamble/max async latency to 6.5ns/9ns, see if it has any effect.
