Dell E6220 SpeedStep - GeekBench Results

Recommended Posts

Hi all, I recently followed the great guide of Herve's E6220 Yosemite installation and I'm so happy with this build and laptop.  I checked the GeekBench result which showed around (4800 - 4900) for my system.

 

I noticed the guide showed a GB result of (6098), which was taken from a finely tuned Mavericks system. I presume the Yosemite build would have the same result or better, or would it decrease due to the OS change.

 

I followed the guide accurately, but I was wondering if I could have missed anything obvious as I am still learning from this.

If anyone could help with this please then great. Thanks CLM

 

Spec:

 

OSX - 10.10.3

BIOS A13 - Default set, except AHCI set

Crucial M4 SSD 128GB (Non TRIM)

16 GB RAM DDR3 1600MHZ

Intel Core i5-2520M @ 2.5GHz (even though my SysInfo says 2.49GHz)

Intel HD 3000 512MB GPU

Chameleon v2468 ?

HWMonitor running (freq only goto 2.5ghz)

Herve's Extra folder applied

10.10.3 kernel

Kexts added to /S/L/E (AICPUPM)

 

 

Results from Console for AICPUPMI.

You have the Sandy Bridge i5-2520M CPU and can therefore re-use the entire bootpack I posted, SSDT table included. There is nothing to worry about SysInfo/SysProfiler showing 2.49GHz instead of 2.50GHz, it's what Chameleon detects and it's a pure cosmetic thing. You may fix that to 2.5GHz by entering a CPU speed of 2500 in the SMBIOS plist through Chameleon Wizard for instance. You may notice that HWMonitor always shows CPU speeds a couple of Hz slower than exactly rounded up frequencies too. That's perfectly normal.

 

HW Monitor should definitely display turbo boost multiplers/speeds in the range x26/2.6GHz to x32/3.2GHz. Your AICPUPM log certainly shows P-States that fall into the whole expected range so you should see the same in HW Monitor...

 

Regarding GeekBench results, bear in mind that this is a CPU test so results may depend on what you've got running at the time you run the test. Consider it mostly OS-independant but you may not get 6000+ all the time and it may be a little lower indeed. 4800-4900 seems much lower that what I would expect on your E6220.

 

For your reference, I've just run a test under 10.11 DB7 and I got 6068 with cDock + HWMonitor + Display Menu apps running in the background and BT + Audio + Wireless + Battery + clock monitoring in the Finder's bar.

 

You say your SSD is in non-TRIM mode; is it by choice or because it does not support it? Update to Yosemite 10.10.5 and you'll be able to use the trimforce Terminal command if your SSD supports the feature.

 

Anyway, I would not worry about anything if I were you, your E6220 appears to run Yos just fine.

Thanks for the quick response Herve. I will definitely looked into the SMBIOS fix.

As for the CPU check, there isn't much happening in the background as the build is fairly new. It's an observation at the mo and really happy with the build and is super fast compared to my beloved D630.  Even though I am missing the ModularBay's some what.

 

The only issue now is iMessage like all other users at the mo. I know message_debug fails with the ROM and MLB.

 

I don't want to waste all the time changing ROM's and MLB's, if it can't be achieved, so could you please let me know if this build/chameleon/FileNVRAM will work with iMessage with the correct setup.

 

Thanks once again. CLM

Thanks for the update. That's a pretty hefty score with all those apps in the Finders bar.

Not sure of the difference to be honest, probably something minor as always.  

 

Anyhow, my machine is v.snappy with that score and v.happy, but we all want to push it, that little further. Then the Build breaks ...  :shock:

 

As for the SSD Trim, I thought I saw somewhere where it was disabled, maybe an older E6220 blog/build. I did TRIM it before on 10.10.3 with TRIM enabler app i think. Well it changed the TRIM support option in the SysInfo to Yes. But have re-built since then. So will try that also.

 

Thanks Herve for your advice, and no benchmark races just yet :)
