Is my PII 1055T Overclock okay?

post #1 of 4
Thread Starter 
Hello good and knowledgeable people of OCN.

I am a long time lurker and rare poster. I'm here today to seek the opinions of people more knowledgeable than me on my 1055T OC. So without further ado here it is.

Hardware:

CPU: AMD Phenom II X6 1055T
Motherboard: Gigabyte GA-890FXA-UD5 (F6 BIOS)
Cooling: Corsair H80 (stock fans [low speed], exhausting out back of case)

Settings:

CPU Clock Ratio - x14 (3808MHz)
CPU NorthBridge Freq. - x10 (2720MHz)
CPU Frequency (MHz) - 272
HT Link Frequency - x9 (2448MHz)
Memory Clock - x5.33 (1449MHz)

Voltages:

DRAM Voltage - 1.510V
NB Voltage - 1.230V
HT Link Voltage - 1.220V
CPU NB VID Voltage - 1.3000V
CPU Voltage - 1.4500V

So questions are, are these settings and voltages okay? Should I be aiming for something different? Is it safe to run these settings 24/7?

Thank you in advance to anyone who takes the time to look at my OC and advise me on it.

Drop your HT link multi, get the speed between 1900-2100 mhz. Your vcore seems a little high for 3.8 ghz, have you tried dropping it some?

 

Also, You could probably take the nb up a little higher. You get a good performance bump from that

Hi Yumyums, thanks for responding.

I've tried what you suggested.

Current settings are now

Settings:

CPU Clock Ratio - x1 (3809MHz)
CPU NorthBridge Freq. - x10 (2930MHz)
CPU Frequency (MHz) - 293
HT Link Frequency - x7 (2051MHz)
Memory Clock - x5.33 (1561MHz)

Voltages:

DRAM Voltage - 1.510V
NB Voltage - 1.230V
HT Link Voltage - 1.220V
CPU NB VID Voltage - 1.3000V
CPU Voltage - 1.4250V

OH NOES!

Started Prime95 on the new above settings and Worker 5 failed in 5 minutes frown.gif

What do you reckon I should do about that? Put the CPU voltage back up? Give the NB more voltage now that it's higher? Something else?

Try using a 300Mhz bus clock to start with to allow your memory to run at about exactly 1600Mhz (easier config that way) and set the rated timings and voltage.  You have plenty of headroom to work on CPU/etc overclock by raising frequency from there.  ONE AT A TIME though.  Keep CPU-NB down while raising CPU and testing to ensure stability, then take the CPU-NB up with you.  Leave HT link frequency at 2000Mhz +/- 200Mhz as always.
