Dear forum friends
I ask for help with a problem that is about to drive me crazy. I bought a new PC and performance is ridiculously low, like about half of what it should be, like my 4 year old machine.
Gigabyte MB-B85M DS3H
Intel Dual Core G3220
3GB DDR1333 RAM (1GB-2GB Dual channel)
No external video card
Source 300w certified, which works well with a i3-2100 another MB. (Note: The MB has 12v 4x2 connector but the manual indicates that it works well with 2x2, so I did)
Hard Drive WD5000AAKX
Windows 7 Professional 32bit
The problem is that absolutely ALL benchmarks report a performance that is about 50% of what they say all the reviews for this processor, and almost 10-20% BELOW my very old Core2Duo E8400. I have run Aida4.6; Superpi and Performance Test 7, with the following results:
AIDA:
CPUQUEEN: 6102 (This is a joke ?? My Core2Duo produces 13000)
PHOTOWORXX: 5900
ZLIB: 70MB / s
CPU AES: 257MB / s
CPU HASH: 980MB / s
FPUVP8: 1391
FPUJULIA: 2920
FPUMANDEL: 1408
FPUSINJULIA: 917
-------------
SuperPi: 19 sec (My E8400 does in 12 seconds)
----
CPUmark: 1890 (in other reviews is above 3000)
2DGRAPHICSMARK 330
3D GRAPHICS MARK: 380
PassMark RATING: 1017

I do not know what can be happening. I updated bios, I reviewed source, settings and I do not know what can be happening.

Am I doing something wrong? Please help me.

I don't think your memory is really running in dual channel. Since you have mixed densities in the slots, I don't believe it will really run in dual channel.
The clock speed of your new CPU is the same as the E8400 but has half the cache. Half the cache would make it more susceptible to main memory quirks.

Since you are showing about 1/2 performance could you have the number of CPUs limited to 1 somewhere, either in the BIOS or in the WINDOWS config?

Thank you friend. The problem is that others g3220 are well above e8400 in all tests. It should also not be the same, being a processor 4 generations later. I have looked in bios and settings that are on the two cores. Do you think that can happen otherwise?

The webpage I looked at showed the "single thread CPUMark" to be approximately what your number is. That is what made me think maybe you weren't using both cores.

So windows task manager shows two CPU boxes in the performance tab? When running the benchmarks are both cores tasked?

Yes, friend. I see two boxes CPU usage. I verified there is 100% activity both when benchmarks. At AIDA is possible select 1 or 2 cores. With only a core the performance is still lower.

Does CPUz show the appropriate clock speed when the benchmarks are running?

Since I think your memory is not optimized with the 1GB/2GB DIMMs, it would be interesting to see if you benchmark scores improve if you run with JUST the 2GB DIMM.

I will try that tonight, my friend (I'm at my job now). Thank you very much for your help. I will write again later.

Hi, Kanewolf.
First, THANK YOU for your help.
The issue is solved (pure lucky)
It appears that the HighDefinitionAudio driver, integrated in Intel HD Graphics causes the problem.
I deleted the Win7 installation, then installed XP, then run benchmarks and I got the real performance at all tests (i.e. 15000 for CPUQUEEN). So I tried win7 again, without drivers, and got same performance. Installed driver one to one, and testing performance every time. When I installed HD Graphics, performances dropped again to 6200 at CPUQueen. So, I uninstalled it and I recovered performance. Then, I installed the driver deleting before the HDaudio files, and Installed HD Graphics and the performance did not below.
I dont know why, but if there is someone with this trouble, should try it.
Sorry bad english.
thank you.
