Think I'll give 200x21 a try and see what she does. If I don't come back, she blew up!

 

[Rubycon]

I bet if I pumped the X6 back to 3.7 (even speed) it would neat the 920 !

I should hope so! It has six cores!

4200 is the sweet spot for most retail 920/3520s. Although 90 pct of my parts are Xeons they are similar in limits. Some need ratcheting the vcore up at 4GHz and some don't approach that turn until after 4.3. The latter ones are quite desirable for obvious reasons. 4200 should be doable without unreasonable (> 1.4V) voltage on core/vtt. Your temps may skyrocket especially with LinX if you don't have a super cooler though.

 

[Amused]

Well, it took a CPU voltage bump up to 1.3 but I'm at 4.2 now. DDR3 @ 1603

Relative Speed: 32.03

Kilo nodes per second: 15372

Not a bad bump. Temps seem very close to the same. Maybe 1 degree higher at idle.

Gonna stability test with Intelburntest now.

 

[Rubycon]

1.3 at 4.2 is decent.
Verify voltage though!
If 1.3 is set in BIOS and vdroop is off (Award BIOS) or LLC ON (Phoenix BIOS) then under load your actual vcore is probably closer to 1.4. If you're idling at 1.3 and dropping down to 1.25 or so under load and stable at 4.2 you have a good cpu!

I have a Noctua DH14 both fans on full in an Antec 300 all 5 fans on med. So I'm covered.

I was at 4.0 using 1.275V. It took a bump up to 1.3V for 4.2.

Temps are 30c idle. And it hit 66c while running standard linpack 8 threads.

Just passed 5 passes at standard on the intelburntest 8 threads (uses linpack). Gonna try max now.

I don't think I have vdroop on this Asus board (p6x58d Deluxe).

Asus probe shows 1.29v. Will check under load.

Hey Mark, curious...were you having issues maintaining the 4.1 o/c? Too much juice required?

 

[Amused]

Okay, just passed 5 passes on max/8 threads. Temp hit 69c.

Vcore never budged. Stayed at 1.29.

Sweeeet...go for more!

Bah! I WAS gonna stop at 4.0/1.275v and be happy with my good luck.

When I put this rig together, I was ready to be happy with 3.5-3.8.

I'm just worried about longevity. Seriously, how many years can this thing go at 4.2/1.3v?

I may just drop back down to 4.0 just so I'm not volting it so high. Makes me nervous.

Are you checking this in CPU-Z?
The default setting on ASUS is Loadline Calibration = AUTO. That will prevent excessive voltage drop/droop under heavy load.

Next up would be 205/206 BCLK for 4.33GHz action.

Gotta push it until it stumbles then back off a bit for margin of safety and keep things stable.

It will run far longer then you're willing to keep it! (unless you like to keep your computers for 5+ years!)

When I got my first W3520 I thought the same thing - 4GHz "holy grail". Then 4.1, 4.2, 4.3, 4.4, 4.5 and you get the idea. It's like walking the street at night blindfolded and someone has removed the man hole covers. Eventually you have to fall in!

CPU-Z shows 2.88 steady. I'll check my BIOS for what I have loadline calibration set for. BRB...

 

[Amused]

Okay, loadline calibration is set to enabled. I thought it was... needed to make sure.

That's what I want, right?

Seriously, how much does going over 4.0 effect longevity?

Makin me kinda nervous.

If you're running 4.2 at 1.3 that's fine. The guys that degrade or pop (as some say! ) their chips are running MUCH higher VCORE/VTT/IOH voltage. I set LinX to run for 300 minutes instead of number of passes. If it passes then you are good to go.

Well, I'm back to 4.0/1.275v. She bluescreeened during my last test with an "IRQL_NOT_LESS_OR_EQUAL" error.

Any idea what that means?

 

[Rubycon]

Not stable!
What are your other voltages like such as uncore and memory?

Hope you can read this ok!

Intel SpeedStep Tech.. Disabled
Xtreme Phase Full Power Mode...Enabled
BCLK Freq..............200
PCIE Freq...............100
DRAM Freq.............1603MHz
UCLK Freq..............3200MHz

QPI Link Data Rate....Auto Change to lowest allowed value!

CPU Voltage Control..Manual

CPU Voltage...........1.3 (now 1.275) Try to keep this below 1.35V at FULL LOAD. If higher don't go over 1.4V and monitor loaded temps as well. They should not go over 85C continuous.
CPU PLL Voltage......1.80 This one is tricky. On non enthusiast Asus boards 1.8 is the minimum. Most will tell you 1.5~1.65 is ideal at higher BCLK. Unfortunately you cannot set it that low!

QPI/DRAM Core Voltage.1.25000 Raise this to match your VCORE at min. 1.35 would be a good start. Keep this below 1.4 though.
IOH Voltage.............1.14
IOH PCIE Voltage.......1.50
ICH Voltage..............1.20
ICH PCIE Voltage.........1.50
DRAM Bus Voltage.......1.64

CPU Differential Amplitude...800mV Set this to 1000mV or AUTO

CPU Clock Skew..............Delay 300ps Set this to AUTO. This MUST match IOH Clock Skew below!

CPU Spread Spectrum......Disabled
IOH Clock Skew.............Auto
PCIE Spread Spectrum....Disabled

C1E Support................Disabled
Hardware Prefetcher.......Enabled
Adjacent Cache Line Prefetch..Enabled
Intel Virtualization Tech..... Disabled

Execute Disable Bit..............Enabled I usually disable this. It does not affect stability but is not needed either.

Intel HT Tech.....................Enabled
A20M................................Disabled
Intel SpeedStep Yech..........Disabled
Intel C-State Tech............. Disabled

 

[Amused]

I can read that fine. Thank you.

I will try those settings and see how they work. Had no idea qpi/dram core voltage should match VCORE. BBL with the results!

It does not have to match it but qpi should be higher and ALWAYS within 500mV of your RAM voltage. (per spec they claim exceeding that can damage your CPU but I have yet to do it with higher spreads - better safe than sorry though!)

 

[Amused]

Okay, tried it a few times and couldn't get it stable at 4.2.

It would pass intelburntest at standard setting/8 thread, but would freeze up on max setting/8thread.

I didn't feel comfortable going over 1.3v even though I know it's supposed to be safe up to 1.4.

I'm very comfortable and stable at 4.0/1.275v. It's rock solid here and can run linpack 8 thread max mem all day.

Think I'll stay here. I'm retired now and can't afford to fry anything.

I have my QPI at 1.3v now.

Can't complain, though. Like I said, I was set to be happy with 3.5-3.8 max. That it did 4.0 without breaking a sweat was just icing on the cake.

What I REALLY want now is an SSD (torn between C300 and Vertex 2) and a second GTX480. I think that will bring me a LOT more happiness than 200MHz. That Mafia 2 benchmark and demo thread in the graphics forum showed me that one 480 just isn't enough. I had planned to SLI with this from the start, though. That's why I went with X58.

I think I'll be holding off on the SSD until the supposed price drops and capacity jumps later this year.

 

[Rubycon]

Yes ALMOST stable at 4.2 shows it's doable with more effort HOWEVER at 4.0 you'll have a comfortable margin that allows for warmer ambients and reduced cooling from dust, etc.

Adding another 480 definitely gets the kick in the pants feeling going. I'd recommend a 1200W PSU though. 1000W will handle it but at extreme loads it will run warm.
