Anand doesn't like 4x4

Can anyone point me to a benchmark review of QuadFx 4x4 using anything other than 32 bit XP? Didn't think so. These reviewers need to run some XP Pro x64, Server 2003 SP1, Vista, Linux before writing the final words. Also given that AMD is already testing true quadcore Barcelona (also...

AMD 4X4 review

Few people buying a high end system like this would intend to run the 5 year old 32 bit windows XP as its operating system. XP32 doesn't support NUMA. Newer OS like XP Pro x64, Server 2003 SP1 and Vista, not to mention Linux, DO support NUMA. It is unsurprising that Anandtech found higher...

Via C7 Processor

In general, the C7 won't really run most applications like games anywhere near as fast. But you are forgetting the possible exception of ONBOARD HARDWARE ENCRYPTION and TRUE NOISEBASED RANDOM NUMBER GENERATION. I would buy several C7 for these reasons. My issue is that although it was...

Let's say Conroe and AM2 came out today

Hmmmmmm, I think I'd go for the Quad core socket F OPTERON with a closely coupled Xilinx FPGA. Oh sorry, if I had to choose, well note that the Conroe is not so big a percentage ahead, and that NONE of the preview benchmarks looked at lots of FLOATING POINT MATH. ie Intel might still be...

Any Conroe ready motherboards out??

Yes it is a good question, I was asking it myself about 3 weeks ago. eg Gigabyte responded since there is no Conroe on the market yet we cannot say if it will work. ANYWAY The conclusion I came to is that NONE of the 975X based boards on the market will support Conroe. HOWEVER, in...

Question about mobos with SLI

What are you trying to display? A windows desktop and apps can span all three screens and drag around. If you are playing HL2 or CS:Source or other games, don't assume you will get some amazing panorama across all. That's what SLI is for. But it may be possible to do some SLI-like comms...

Question about mobos with SLI

Yes indeed the second "sli" slot can be used either for other pcie cards like scsi, network, or in fact video cards. They do not HAVE to run in SLI. As you will not use them in SLI mode there is no need to use the "BRIDGE" connector. Your motherboard manual will tell either bios settings or...

PSA: The correct abbreviation for PCI Express is PCIe

Actually THEY DID call it something else. It was "3GIO" ie 3rd generation I/O. or "Next generation I/O". Unfortunately, the first might be confused with 3G mobile phones, and there were other competing standards for next generation like "Future I/O". So probably it was some marketing...

motherboard with most 4x PCI-E slots?

If you want to work with 10 Gigabit ethernet, you will be talking x8 cards. Go buy a couple of these http://www.myrinet.com/Myri-10G/NIC/10G-PCIE-8A-C.html for $795 each. I doubt you will find any much cheaper or as FAST! With additional software $$$ and a myrinet switch they will also...

PSA: The correct abbreviation for PCI Express is PCIe

In that case refer to the specification for the correct terminology. Which is..... 16 LANES comprising one LINK which may be described as a "x16" link. However, also distinguish between physical slots, and the number of active lanes on that slot at any given time. Eg put two graphics...

PCIe 1x cards?

Just a bit of lateral thinking, but most PCIe systems have lots (8 or 10) USB2 ports. Perhaps consider a USB2 wireless networking "dongle". They are cheap compared to card based versions, and as has been said, standards like 802.11A, N (final not pre) and WIMAX will mean you don't want to...

PCIe 1x cards?

TERABIT cards? I don't think so. Remember that for each pcie lane an 8/10 encoding scheme is used so the actual rate is less than the raw gigabaud rate. Now x4 PCIe is NOT sufficent to handle even 10 Gigabit/s ethernet. That is why Myrinet use x8 lanes for their 10 Gigabit/s cards which...

PSA: The correct abbreviation for PCI Express is PCIe

NO, this is NOT a trivial issue. There was PCI. Then there was an improved faster/longer/widertransfers version called PCI-X developed by the same group of people. Now there is the next generation PCI Express, by the same group. Unfortunately many lamer people in the computer business...

motherboard with most 4x PCI-E slots?

Just as an aside, something that may be of use to you in this application is a clever little PCIe adapter from Twin Industries. This will hold your X4,X8 or X16 card and allow it to plug into a X1 physical slot. http://www.twinhunter.com/catalog_detail.php?id=303 Of course you only get...

motherboard with most 4x PCI-E slots?

Hi Azeem, Well, first I will say that 4x does NOT translate to 10Gbps. 1 lane of PCI express operates at 2.5 Gigabaud raw modulation rate. It uses at 8/10 encoding scheme which means the MOST possible data you get is less ie a real 250 MByte/sec (or238 Mibibyte/s). Further, you would...
