[Help] Problems with my overclock ! R3E + 980X !

Hey, guys. Looks like I'm having problems with my computer.

I can't make my cpu stable and all hardware is new!

The maximum frequency that I reached was 4Ghz on 3DMark Vantage with voltages @ auto and temperature @ full load around 52ºC.

Above that, something weird happens and the system crashes at cpu test with less than 1 second running.

I did it all with memories, uncore, qpi, nothing worked.

I use watercooler.. i don't believe that's the matter...

Anyone know what can it be?

Where am I doing wrong??

Checklist:

Cpu configurations: ALL OFF (exceto HT e ALL CORES)
Cpu Voltage OCP: OFF
QPI, PLL Voltage OCP: OFF
CPU PLL: 1.30v
VTT/QPI: 1.35v ~ 1.50v (Unsuccessful)
Vcore: 1.50 ~ 1.65v (Unsuccessful)
Clock testado: 4200mhz ~ 4812mhz (Unsuccessful)
Uncore: 2800mhz ~ 4000mhz (Unsuccessful)
Cpu Ratio: 29 ~ 35x (Unsuccessful)
Load line: Full Calibration
Mode: X-Power
PCI Express: 102
Spread Spectrum / CPU e PCI: Disable
Hardware Prefetcher and Cache: Enable

That's all that I remember for now.

I updated BIOS, cleared CMOS.

Need help here!

Help-me Please !

Also be really careful with voltages, Vtt 1.5v is scary stuff, so is 1.65v on water, you don't need anything like that for 4-4.5GHz and 32nm cpu's are very sensitive to it.

Try this though:

Cpu configurations: ALL OFF (exceto HT e ALL CORES) Turn TM on incase something happens and you need it
Cpu Voltage OCP: OFF
QPI, PLL Voltage OCP: OFF
CPU PLL: 1.30v Set this to default 1.80v and only change it later on once things are stable
VTT/QPI: 1.35v ~ 1.50v (Nada com sucesso) Keep this under 1.40v max, the lower the better! (to a point)
Vcore: 1.50 ~ 1.65v (Nada com sucesso) - way to much vcore, keep it sane. 1.375v (real) max for now
Clock testado: 4200mhz ~ 4812mhz (Nada com sucesso)
Uncore: 2800mhz ~ 4000mhz (Nada com sucesso) - use the lowest or second lowest setting
Cpu Ratio: 29 ~ 35x (Nada com sucesso) - Try 25-29x to start with.
Load line: Full Calibration - I use 50% LLC its better for your CPU
Mode: X-Power - try T Balanced + Power, works fine for most of us
PCI Express: 102 - why 102? Set to 100 to start with
Spread Spectrum / CPU e PCI: Disable
Hardware Prefetcher and Cache: Enable


Set your ram speed to around DDR3-1500 to 1700MHz and use loose timings to start with. Use 1.64XXX vdimm to start with.

Thanks for the help.

I tried using 4500mhz less than 1.50, it was not possible.

Not tested lower multipliers, I'll do it tomorrow.

There may be a processor (batch) so bad?

I am grateful.

Edit:

Oh god, I'm having the same problems ...

Black screen without launching the video, when it starts, it takes longer than normal.

Problems above 4500mhz, it is perfect with unless.

:(

980X's are difficult to get above 4.5 ghz unless you're on sub zero or a very good batch on air, and even great air batches usually need >1.45v for 4.5 ghz.

You look like you had some success at lower speeds I know you were able to get more than 4.1 ghz. What was the highest speed (at sane voltages) you achieved?

And you shouldn't go above 1.45-1.50v vcore on water.
That 1.30 PLL was definitely a serious problem early on. Way below default.

Fully agree with this ...:up:

Its ok !

The best I got was stable:

4495mhz with 1.50v
BTT: 1.40
Uncore: 3200MHz
Memory: 1684mhz
QPI link: 5200, More or less

I'll follow the tips CryptiK friend this afternoon, and give feedback to everyone.

Please, post, help-me, I need to fix this.

High investment not to succeed in benchmark.
