When you installed the second memory module, you enabled dual-channel mode and doubled memory bandwidth. GPU performance is highly dependent on memory bandwidth and your frame rates reflect the increase in bandwidth. The AMD A10-6790K is an "Accelerated Processing Unit" (APU). APUs combine a CPU with a relatively powerful integrated graphics processor ...

From Motherboard, CPU and RAM Troubleshooting, if you do not get any beeps but can hear the fans, then it is probably a motherboard failure (but do read this on-line book entirely). Some of the tests require having some spare-parts on hand, so can be better done by a tech-shop. See also Laptop CPU Failure Analysis and Solution can be helpful with its ...

Yes, you can use amd64 on your Intel Core 2 Duo. The architecture is named after AMD because AMD invented it, with the Athlon 64. Similarly, the 32-bit i386 architecture is named after Intel's 386 processor, because it was the first of its kind, but i386 will also work on AMD processors.

Multi-core CPU:s can perform several actions per clock cycle, loosely speaking. The clock speed is measured in Hz, and it is not correct to say that it is tripled just because you have more cores. Everyone loves car analogies! A three-file motorway as compared to a one-file motorway with the same speed limit will not predictably enable you to arrive at your ...

Because the use fundamentally different bus architectures; see HyperTransport and QuickPath Interconnect for the details. Physical similarities in the arrangement of pins, etc, are mostly down to the physical realities of building a CPU dictating much of the form. At a larger scale, the answer is: because they believe they have more to gain from ...

You have an APU, rather than a discrete CPU and discrete GPU. That means that they share system RAM for the texture cache, rather than dedicated on-board memory on a graphics card. The reason the RAM upgrade sped things up for your game likely is because of texture resource swapping. With more RAM available overall, that means more texture data is able to ...

The CPU type should be in the environment variable %PROCESSOR_ARCHITECTURE%, and echo %PROCESSOR_ARCHITECTURE% in the command prompt should give you AMD64 on a x86-64 processor. msinfo32.exe should also have a "System Type" field, which says x64-based PC for me on a x86-64 processor. I'm not sure how/why you have a IA64 system binary... It seems to be a ...

I've saw the names of some instructions that we're added on SSE, however there's no explain about all of them (Maybe SSE4? They're not even listed on Wikipedia). Where i can read about what they do? The best source would be straight from the people who designed the extensions: Intel. The definitive references are the Intel® 64 and IA-32 ...

It automatically reduces your CPU multiplier (slows CPU down) when the computer isn't doing much. It's a way to save power. And according to this page, your CPU supports it.

More than just reducing the CPU multiplier goes on in C1E. The Processor to processor and processor to chipset links are also put into low power (high-Z) state. Allowing the whole platform to use less power but still appear to be on to the user. From an AMD Blog: C1E is a power management state that allows the processor to reduce power beyond just ...

AMD K8 is a processor microarchitecture, which was the first to implement the AMD64 instruction set as an extension to the x86 architecture. The following x86 processors use the AMD K8 microarchitecture: Athlon 64 X2 Athlon 64 FX Athlon 64 Sempron Opteron (Later also released using K10) Turion 64 Think of it as being analogous to the Intel versions; the ...

Not necessarily, but installing memory in matched pairs will ensure optimum performance. A computer will function with only one module or with modules with different sizes or speeds, but performance will be less than optimal; furthermore, if memory with different speeds are used, both modules will be limited to that of the slower module. If matched pairs ...

I would count on 6Gbps SATA. All of AMD's chipsets in manufacturing since mid-2010 have 6Gbps SATA. Also a look at the Fusion platform shows that they work with a new south-bridge - "Hudson FCH" which is an evolution of last year AMD's latest chipset - SB850. Very similar notebook by HP was reviewed by AnandTech: ...

Yes, all Athlon 64 X2 processors are 64-bits. You can upgrade to Windows 7 64-bit. I don't know why your system information says it's a 32-bit processor. Perhaps because you're running a 32-bit OS, it is showing you the mode that it's currently running rather than the full capabilities of the processor.

Head over to Catalyst Control Center, Crossfire tab & uncheck the checkmark against Crossfire.

This is a common problem with default settings of Catalyst Control Center. To fix: open Catalyst Control Center go to My Digital Flat-Panels choose Scaling Options slide the slider all the way to the right (so that it is a 0%)

Both temperature and voltage kills a CPU. A high voltage spike can kill it quickly. In your case I wouldn't worry though. The voltage spikes you have are still low. The Intel spec sheets specify the max vCore VID as 1.52v for that processor. Now, I wouldn't actually run the processor at anything near that, but on the other hand I doubt a voltage spike up to ...

I know for a fact that with my HP laptop, no AMD driver download works - you have to get it directly from the HP website... and it is an outdated rubbish version. Unfortunately, I don't think AMD have changed, and, the catalyst download is mainly for people who have an unlocked laptop / one that allows you to install whatever drivers you want. If this is ...

I solved the issue myself after a lot of testing. As it turns out, the Setup.exe that AMD gives you doesn't always actually install the graphics driver. It installs the Install Manager, CCC, and the HDMI Audio driver, but not the graphics drivers. Below I'll lay out the steps for solving this: Open the device manager and select your Graphics Card in the ...

Yes, it's a desktop with a PCI Express x16 port, put whatever you want in there, well, within the limits of your power supply that is. Since the 7750 requires no dedicated 12V, you should be fine. As far as a second card goes, I think that motherboard only has ONE PCI Express x16 slot, so don't get your hopes up.

From some AMD presentation: Each SIMD unit contains 16 stream cores, and each stream core houses five processing elements. Thus, each compute unit in the ATI Radeon HD 5870 has 80 (16 × 5) processing elements. Analogue for CUDA core is Stream core, and SIMD unit is analogue to nVidia's Streaming Multiprocessor. The difference between CUDA core and ...

Universal replacement parts fit universally badly. At one time when AMD was licensing from Intel to produce 386 and 486 chips, it was possible, but with the Pentium forward, this compatibility disappeared with divergence between the Pentium and the AMD line. This led to the necessity of having different support chip sets and therefore different ...

Yes, the cards can have different chips as long as they are the same generation and family. Specifically, the 5850 will work with any card starting with 58xx (and also with the 5970, which has two 58xx processors). It won't work with 57xx cards (different family), or with 68xx cards (different generations). It is not mandatory that the manufacturer is the ...

"AMD K8" is the processor. "AMD64" is the instruction set.

Go look at Tom's Hardware cpu comparison charts. They runs tons of tests and list many processors. A great resource for CPU's and VideoCards

I think it's a placebo effect. IMHO a system with 512MB can't run very smooth. I had a nice system once that had 512 MB RAM, too, and a fairly modern Processor (at that time). Then i worked with a better system for a while. When i got back to my own machine everything seemed so slow, even if nothing had changed. In the end this is a dupe of ...

I believe I may have found the answer. When I disabled the BIOS setting for AMD Cool n Quiet, my performance jumped to 178% of my old system, which is a little bit faster than my very comparable work hardware. A lucky catch, really, since I only tried disabling C&Q because I have beeen having occasional crashes. I also pushed the memory from 1T to 2T ...

As long as you get 2 video cards that each have 2 DVI outs each, you should have no problem. The Nvidia/ATI software should help you set up your 4 monitor configuration. Also, as Dan mentions below (thanks!): Note: If a video card has 2 outputs, 1 DVI and 1 VGA, this may not work to go to 2 monitors even if you have a VGA->DVI converter. This is ...
