My First 4ghz Overclock (980x)

[Henrik]

ok blue screen or just a worker failed? and how long into prime?

 

[Hay11Mac]

Worker failed, and then Prime95 stopped working "needed to close"

Was about 8-10 minutes in

 

[Henrik]

Ok just a test: What do you think we need to increase?

and how much?

 

[Hay11Mac]

The QPI/DRAM from 1.30v to maybe 1.32v?

 

[Henrik]

Yeah you are learning

yes increase QPI to 1.32-1.34

 

[S1EJ0]

No RAM is at 2000mhz Timings 8.8.8.24, although CPU-Z says DRAM Frequency is 1002.4mhz but in bios its set to 2005mhz

If your ram is the same as mine they are rated at 8-9-8-24. They don't like 8-8-8-24 without again more QPI/VTT voltage and maybe more VMem.

 

[Hay11Mac]

Leaving vcore at 1.30v right?

 

[Henrik]

Leaving vcore at 1.30v right?

Yeah I would..

 

[S1EJ0]

Leaving vcore at 1.30v right?

1.3V should be plenty Vcore for a 4GHz OC

 

[Hay11Mac]

If your ram is the same as mine they are rated at 8-9-8-24. They don't like 8-8-8-24 without again more QPI/VTT voltage and maybe more VMem.

It's corsair dominator 2000mhz ram, say on the side of the ram 8.8.8.24 which is why I set it to that, but I will change it if you think that maybe the problem?

 

[Hay11Mac]

Ok running prime again now, change QPI/DRAM TO 1.32v

 

[S1EJ0]

No if thats what they are rated for then that is fine. Obviously its a better kit than mine!

 

[Hay11Mac]

Also says on the side 1.65v, I am guessing the the DRAM Bus right?

 

[Henrik]

Also says on the side 1.65v, I am guessing the the DRAM Bus right?

you are 100% correct

 

[Hay11Mac]

Woohoo am learning LOL so cuz the ram is running at 2000mhz it needs more volts?

Why does CPU-Z only show DRAM frequency at 1002.3mhz, when in the bios it's nearly double that?

 

[Hay11Mac]

Prime95 has crashed "Prime95 application has stopped working" although no workers failed, or not that I saw anyway

A worker did fail number 8 grrrrrrrrrrr!

 

[Henrik]

once again i would try increasing the QPI. Go for 1.35V. did it run any longer then last time?

As for the memory speed reading in CPU-Z, its normal it has somthing to du with the memory being doul-channel or somting like that

 

[Hay11Mac]

I have put the QPI TO 1.34v did it before I got your message,

Ran for about same amount of time I think......

It's kinda a nightmare to get stable huh?

When I am upping the QPI volts the ram that prime95 uses is less, 3.05gbs now

 

[Henrik]

Well OC'ing can be VERY! frustrating but the first time you overclock you have no idea what sort of voltage you need so its just a matter of going up and up until you find a stable voltage. (nut ofc. not to high)

As Joe wrote he needs 1.42V QPI to be stable so keep trying

if 1.35V dose not work go for 1.4V

 

[Hay11Mac]

Could my motherboard be at fault here, cuz I'm not 100% it's ok, as like I said a while back USB connection keep connecting disconnecting (not keyboard etc but like my iPhone, and an external DVD drive, I can't burn anything with it, cuz when it goes to power up it disconnects (if you know what I mean)

But if my motherboard has become faulty this might be the reason for the unstable ness?????
