Help getting 1055t stable at 4ghz.

post #1 of 9
Thread Starter 
Hi!

I just managed to boot into 4ghz and I was amazed by how much faster windows loaded all my startup programmes.

However, of course I encountered a problem.

After launching Intel Burn Test, my PC reboots after a few seconds.

What could this be? Can it be everything from the CPU to the NB to the RAM?

CPU: 4050mhz
Multiplier: 13.5
FSB: 300
NB: 3ghz
RAM clock: 1599mhz
Timing: 9-9-9-24

DRAM Voltage: 1.5v
CPU NB Voltage 1.275V
CPU volt: 1.475


Any help? THank in advanc!

The CPU-NB voltage is too low for a 3000mhz NB. Try bumping it up to 1.35v-1.4v and see if it helps to stabilize it. You may also need a higher vcore, but try the CPU-NB first.

That has nothing to do with the fact his comp restarted
"but still the truth"
Do you have a heatsink over your mosfets?

they get REALLY REALLY HOT like i touched mine once and it blistered my finger,this was

right when i got the motherboard, i since then have put a mosfet heatsink on them.

Its called enzotech mst-88 it fits perfect, and i also have a small fan blowing on it.

The chipset on this board both the mosfets, and the chokes, and the nb get abnormally hot on this board for some reason, put a fan blowing on all of them and see if your prob remains.

It could also need some more Vcore.

CPU-NB voltage could definitely use a boost, I need 1.375V for 3Ghz to be fully stable which is pretty average.
GA-870A-UD3 mosfets getting hot? I usually don't recommend mosfet heatsinks for this board until reaching 1.5-1.55V, thanks for letting me know. I'll definitely be recommending adding mosfet heatsinks more now. I'd think the 8+2 would've ran cool enough.

Thanks for all answers.

Solar0987 I have exactly that heatsink, got it a few days ago .

When I started to OC the first time I got to 3,6ghz with auto on Vcore. My Vcore was then 1,2v, which I thought was amazingly low (ran the same Vcore on 2,8ghz and 3,6ghz).
So I'd love to get 4ghz at a low Vcore (and thus being proud to have a golden chip).


About the NB. Should I aim for 3ghz and thus having more volt on CPU-NB or keep it at stock (2ghz)? Would it benefit a lot?



About stability tests in IBT, I do not recieve a BSoD, my PC just restarts and acts normal again.


Can it be RAM causing the instability or have you stated its probably the NB+

How are the RAM timings? I'm completely noob at RAM so dunno anything about RAM.


cheers

Random restart? That is either CPU instability or NB instability. Since NB not OC-ed probably CPU. Of course OC the NB! Huge benefit if you get it to 3Ghz at ideally 1.35-1.4V.

btw what does a BSOD mean when running prime test? That's vcore isn't it?

I now tried to run it with 1.5volt, still restarted Must it be CPU related or can it be anything else?

Also I cannot boot if my NB is at stock, at 3ghz I can however.

So what else to try? Can it be my RAM in any way?

Thanks in advance
