Intel Quad Core Processor in '07

Hello,
At the Intel Developer Forum in San Francisco this week it was announced that a quad-core desktop processor will be unveiled in January 2007. The 65mn 'Kentsfield' Core 2 Quad CPU will be preceded on November 16 by the 2.6GHz Core 2 Extreme QX6700, a quad-core CPU with 8MB total cache, operating on a 1066MHz FSB and spitting out 130W of heat. The first kick at the 4-core can will see two physical silicon dies integrated onto one CPU - or in other words two Core 2 Duo's side by side and forced to communicate via the Front Side Bus. Not the most ideal configuration when confronting bandwidth bottleneck issues, but the first logical step towards one silicon / four core solutions. By the end of 2007, 45nm multi-core CPUs will be the norm from Intel.

Early analyst reports coming out of Taiwan are already looking towards the initial Core 2 Quad processors' replacement, the 45nm 'Yorkfield' core. By Q3'07 the quad-core Yorkfield will be introduced, and with it support for a 1333MHz FSB, PCI Express 2.0, DDR3-1333 memory, and most importantly an L2 cache which is split between each pair of processors.

In other words each set of cores will communicate directly, which is a more efficient approach. At the present, it may be recommendable to eschew the first-generation quad-core QX7600 entirely, and possibly even the first Core 2 Quad's in anticipation of the 'Yorkfield' that is expected to follow this time next year. Given the impressive standing of the Core 2 Duo CPU right now, adopting a transitional quadzilla chip a few months from now may not be the best route to take in the long run... although the Core 2 Extreme QX6700 has already been benchmarked by Intel to illustrate select advantages over Core 2 Duo.

Fresh from the test bench today is PCSTATS review of the Epox EP-MF570 SLI and Gigabyte GA-M59SLI-S5 nForce 590 SLI motherboards. Core 2 Duo may be catching the headlines, but socket Socket AM2 AMD Athlon64 platforms are still nothing to sneeze at. With all new platforms on DDR-2 memory, you might want to pop on over and check out this review of the new OCZ PC2-7200 memory, and the Asus EN7900GT Geforce 7900 GT graphics card. Last but not least is look back at the Gigabyte GA-965P-DS3 P965 Express motherboard for Intel Pentium D and Core 2 Duo.

We've posted a correction to last week's Tech Tip below, along with a new one! Remember, PCSTATS Newsletter is now archived, and completely available for online reference. Browse, or run a search through over 200 archived PCSTATS Newsletters!

Gigabyte GA-M59SLI-S5 nForce 590 SLI Motherboard Review
READ

If you're looking for a top of the line gaming system based on the AMD socket AM2 processor, it's almost guaranteed that your motherboard chipset will be the nVidia nForce 590 SLI. If you're thinking about getting into the best AM2 has to offer, the Gigabyte GA-M59SLI-G5 motherboard is a pretty sweet starting point. Onboard the GA-M59SLI-G5 'S-Series' motherboard you'll find a 7.1 channel Intel Azalia compatible audio codec, dual Gigabit network connections, a secondary Serial ATA II/RAID controller, IEEE 1394a Firewire, three physical PCI Express x16 graphics card slots, twin BIOS chips for redundancy, and a flurry of other handy hardware devices. The boards' four DDR2 RAM slots will support a maximum of 16GB of DDR2-400/533/667/800 memory in unbuffered ECC/non-ECC formats. Expansion is taken care of with two PCI, two PCI Express x1, and three physical PCI Express x16 slots (two x16 and one x8).Continue Here>>

Epox EP-MF570 SLI nForce 570 SLI Motherboard Review
READ

The nice thing about computers is that if you do your homework, you can buy yourself a very modular system from the start. First, seek out something built on nVIDIA's nForce 570 SLI chipset; it's not top of the line but offers good value. The nvidia nForce 570 SLI is a single chipset AMD socket AM2 solution, and it's a little cash strapped for PCI Express lanes as compared to the nVidia nForce 590 family. The Epox MF570 SLI has two PCI Express x16 slots for dual graphics cards, and will support SLI, but with each videocard receiving 8 PCI Express lanes each instead of 16. This is an AMD socket AM2 motherboard, supporting all current 940-pin AMD Athlon64 X2. It's four 240-pin DDR2 memory slots will accommodate up to 16GB of double-sided DDR2-800 memory in a dual channel configuration. Storage options are more varied than the new Core 2 Duo motherboards offer; the Epox EP-MF570 SLI has two IDE channels. Continue Here>>

OCZ DDR2 PC2-7200 Platinum XTC SLI-Ready 2GB Memory Kit Review
READ

Overclocking is a ton of fun if you're interested in getting into it.. but ask any seasoned overclocker about the importance of good memory and they'll talk your ear off. OCZ's 2GB PC2-7200 Platinum XTC SLI Ready memory offers users an interesting mix of high speeds and low latency. The 2GB kit has been rated to run up to 900 MHz while keeping CAS Latency timings of 4-4-3-15. The memory requires a stock voltage of 2.1V. The DDR-2 modules come wrapped in OCZ's XTC (Xtreme Thermal Convection) "heatspreaders", and it looks like the entire package has been deep-fried in the chrome-plater! Continue Here>>

Gigabyte GA-965P-DS3 Intel P965 Express Motherboard Review

READ

The future for Intel 's P965 chipset is a bright one, particularly with Core 2 Duo processors finally rolling out the door (actually, physically so). Aside from PCI Express x16 videocard support, the Intel P965 chipset leads with a 1066 MHz front side bus, a new 12.8GB/s 'Fast Memory Access' memory controller, and a few other technologies we'll touch upon momentarily. Gigabyte's GA-965P-DS3 motherboard offers a good mix of performance and value for the remarkably proficient Core 2 Duo processor series, and for the purposes of this review PCSTATS will be testing it with an Intel Core 2 Duo E6600 CPU - the sweetheart of the bunch for its 2.4GHz clock speed and 4MB of L2 Cache.Continue Here>>

Asus EN7900GT TOP/2DHT/256M/A Videocard Review
READ

Assembling a wicked gaming machine can be a challenging task, but realistically the most important device is the videocard. At first glance, the Asus EN7900GT TOP/2DHT/256M/A looks like a normal GeForce 7900GT... closer inspection shows that it is a highly tuned videocard that is faster than the average stock 7900GT. The 256MB Asus EN7900GT TOP/2DHT/256M/A videocard is compatible only with PCI Express x16 slots so that means AGP users needs to get their fix elsewhere. The game comes with a large software bundle which includes a full copy of King Kong, two DVI to analog converters, a component output cable and a six pin molex power connector should your power supply not natively support the new generation of high powered videocards.

PCstats Weekly Tech Tips: Tweaking the DNS

One very annoying feature of the WindowsXP operating system is that it automatically caches failed DNS lookups. It's not a problem when addresses are truly wrong, for instance when you type an incorrect URL, but it can get irritating when the system caches failed DNS lookups for legitimate sites (like if you're having ISP problems). Luckily the fix is easy...

Load up a command prompt (Start -> Run then type "cmd" and press OK), type "ipconfig /flushdns" and press the "Enter" key. After that's done close the command prompt by typing "exit" and press enter. Now open up the registry editor (Start -> Run then type "regedit" and press OK) and follow this path. HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> Services -> Dnscache -> Parameters. In the right hand window create these three DWORD values ("NegativeCacheTime", "NetFailureCacheTime" and "NegativeSOACacheTime") and give them all a value of 0.

From now on your machine will not cache failed DNS lookups anymore, it might take a bit longer for your system to resolve bad websites addresses but at least it won't return false negatives. ;-)

Last issue's Server 2003 and Domain Controller Troubles tip was a bit garbled, the three command lines should have been set as follows:

REG DELETE HKLM\SOFTWARE\Policies\Microsoft\Windows\IPSec\Policy\Local /F
REG ADD HKLM\System\CurrentControlSet\Services\IPSEC /V Start /T
REG_DWORD /F /D 1 regsvr32 -s polstore.dll
