Help with linx stability - i5-750

[joxang]

I'm having problems getting Linx stable with an i5-750 on a GA-P55A-UD3. It never bsods, but always stops with error after anything from 4-8 passes. Running 4GB of generic OEM RAM.

The build is stable with a whole night of prime, and mem test is fine. Load temps are 60 with Linx, and 55-60 with prime.

Currently:
Multiplyer: 19x
BCLK: 200
RAM @ x6, 1200Mhz
VCore: 1.375V
QPI/Vtt: 1.230V
CPU PLL: 1.8V
RAM: 1.5V

I don't really want to go any higher on the voltages though I guess I could bump the cpu up to 1.4V. Would raising the PLL help?

I've never had a crash even when gaming with these settings, so at the end of the day does Linx instability (no bsod) matter for 24/7 usage? Any advice would be great, cheers.

I'm guessing you are using LLC level 2. I'm in the LLC is bad camp and find it to introduces random instability. Opinion is split 50/50 on the use of LLC tho. Personally I'd aim for an overclock using LLC level 1 as it is much less aggressive.

You're also running 200BCLK which will likely require far more qpi/vtt volts than currently being used. My recommendation would be to lower the BCLK and up the multiplier to 21x. If you're running cheap 1333mhz ram with no overclocking headroom you may have to run it at a much lower speedtho. For reference, I run at roughly the same qpi/vtt volts with a BCLK of 189. I need >1.3v for 200BCLK.

Great, thanks for the advice. I'll give it a go .

Slight thread necro, but if anyone's interested, I had to turn on load-line calibration in BIOS to help manage the extra VDroop from linx hammering the cpu on and off. Fixed the instability anyhow .
