Unlocked L3 Cache on Athlon II X3 but not 4th core. Is this normal?

post #1 of 11
Thread Starter 
I received my brand new ASUS M4A88TD-V EVO board, and tried the "Core Unlocker" switch to unlock the fourth core on my Athlon II X3 450 Rana. That was a no go, since the Windows wouldn't load.

I then went into BIOS and tried enabling/disabling each core individually in order to figure out which one was bad. Once I disabled the bad core, the system loaded normally and Windows installed a new CPU driver.

Now, even though I wasn't able to unlock the 4th core, L3 cache has been unlocked according to CPU-Z. Is this normal? Also, is such a large increase in power consumption normal (just for enabling L3)?

Look at these before and after screenshots. Ran prime95 for a few minutes with no issues, but how can I test L3 cache in particular to see if it's fully functional?

Better then nothing at all I guess. I can't really explain why it is jumping up the power. It might be because the motherboard is seeing the chip as a phenom chip now. so it is running as if it was a 125watt phenom II chip.

You got a Phenom II X4 with locked cache and core; you got a Deneb instead of a Propus. Now you have a Phenom II X3.

It's not normal, but definitely possible. The first batches AMD released of the Athlon II X3 and X4 had Deneb dies mixed in with Propus dies.

After running 3D Mark Vantage/2006 about 10 times per cache state, I averaged all scores and there is a measurable increase in performance. I know it's not much, but what the hell, can't complain about free L3 cache. tongue.gif The only thing I'm worried about is whether the considerable increase in power consumption will have any adverse effects on the CPU or not...

3D Mark Vantage CPU Score

Before L3 cache unlock: 7744
After L3 cache unlock: 8206

Difference: 6% improvement



3D Mark 2006 CPU Score

Before L3 cache unlock: 3552
After L3 cache unlock: 3645

Difference: 2.6% improvement


Windows Experience Index, on the other hand, didn't change (in both cases the CPU subscore is 6.9 out of 7.9).

In games there's a boost of 10% overall when having the 6MB L3 cache. Tom's Hardware did a study on that.

There is no increase in power consumption because of the cache, the programs are just reporting wrong. It's the same 95W as before.

HWmon and CPUZ just report the wattage based on what chip you have, they dont actually track your real power consumption.

Check the Advanced Clock Calibration in your BIOS, even though you have unlocked it, the 4th core might still be locked and you need to set it to active. Give that a go smile.gif

There is no ACC in SB850 chips (which is what I have) AFAIK.

Basically, I went to Advanced->CPU Configuration and set ASUS Core Unlocker in BIOS to "Enabled". This by default enables all cores, which resulted in no boot.

Below the ASUS Core Unlocker option there is another option called CPU Core Activation. I changed that from "Auto" to "Manual" (originally all cores were ON and Windows wouldn't load) and started disabling each core one at a time in order to figure out which one was bad. Once I found the bad core, I left it off and enabled the rest which resulted in a successful boot.

Makes sense. However, with HW Mon wattage changes in real time depending on load (I have Cool & Quiet enabled, so CPU multiplier changes constantly). Originally, it would vary between 34W and 103W, while now it varies between 49W and 137W. headscratch.gif
