IC7-MAX3 - P4 2.6 - Hyperthread cause PC to random reboot

Hi!

Have anybody else experienced problems with random reboot and HyperThread
enabled?
Well I have.... I and it has taken a while to sort it out!

If I enable HT I am guaranteed that PC will random reboot whitin the
hour....and I am NOT OC'ed!!

I am reading about voltage problems on DDR, and I am wondering if this
problem with HT is caused by a voltage problem?

Speedy

IC7-Max3
P4 2.6 at standard voltage
Twinmos Dual 512*2 3200 at 2.6v
NOT overclocked!
Chieftec 420W PSU

 

I've not seen that issue with respect to HT and this is also the first time
I've read about it in a post here in the group. I still think you have a
problem with respect to the ram on the board and either the voltage, the
timings for the ram or both. have you tried setting the timings on the
Advanced Chipset Settings page to manual and then setting the timings
purposely high to something like 3, 7, 3, 3 and left GAT on Auto?

get your hands on Memtest and test the system and see if it errors on the
memory tests with HT enabled and the ram in various bios setting settings.

Are ALL MB setting with regard to CPU, FSB and memory set to default
when you get the problem ?

--- CPU default-auto
(Memory by SPD etc.....)
--Game Accelerator Auto

I have actually seen posts from folks where having the DDR set to By SPD
caused a problem which is why I recommend sometimes, setting things manually
and choosing the slowest memory timings as a test.

YES!!

All is at default setting.... all but the disk boot order!!

Speedy

 

Memetest....like the "DOS" boot disk memtest?? would it have the ability to
test HyperThread??


Speedy

 

Not realy, but I have the exact same setup as you have. I get some artifacts
in windows sometimes but I can't remember any reboots (I think it's a
problem with the graphics card).
What OS are you running?

Setup:
Abit IC7-Max3
P4 2.6GHz 800
2 x TwinMos DDR PC3200 (not winbond)
Ati Radeon 9800Pro

Ola Flaagan

 

no, won't test HT but certainly will test RAM and that is where a lot of us
feel the issue lies.

Just sitting in Windows desktop ? Or what ?

John Lewis

 

Win XP Proff.

Just at desktop .....baaaammm reboot.
No errormsg...nuttin...
Just black screen and reboot.
Somethimes it comes while watching movie or other intensive load operation,
so not a spesific pattern.

Graphic is 3D Blaster FX 5600 256mb ram

Speedy

 

I assume that you have a P4 2.6c (800MHz) and not just
a non-HT P4 2.6 (400MHz) ? ( Sorry, I had to ask this really,
really, stupid question, but you only wrote P4 2.6 in your
header and text...)

Use Hardware Doctor or Motherboard Monitor to check
CPU, NB etc.temps while in Desktop with HT on.

If OK, you need to download Memtest or similar and
fully exercise the memory. This is the prime suspect.
If you see ANY errors at all, raise the memory voltage.
Do not exceed 2.8 volts.

John Lewis

 

Yes...it's the PC800 P4 2.6

And yes...have run memtester all night.....Tested ram for 7 hours....16
times with no errors!!
Have tested up to 2.8v, and my only experience is that is has become more
unstable!!

Speedy

 

well, if your DDR tested with Memtest and found no errors, then you have
given me enough to say that I agree that it is not ram problems. something
else is going on if you can pass a bunch of memtest...

AFAIK, you never reported your temperatures............presumably well
within reasonable limits ?

John Lewis

 

you're probably posting to SpeedyGonzalas but just for reference, mine are
around 45-48 at idle and 59 to 61 under heavy load.
