some motherboard/ cpu/ ram questions
What is the difference between 3.0 and 3.0E ghz? The only difference
I see in the specs is that the 3.0E has a larger cache. What does serial ata/ ultra ata mean? What's the difference between single and dual channel memory? What is raid for? Thanks for any answers you can give. |

... " What is the difference between 3.0 and 3.0E ghz? The only difference I see in the specs is that the 3.0E has a larger cache. " The 3.0C has a 130nm Northwood core. It has an L1 cache of 12KB + 8KB, and an L2 cache of 512MB. The 3.0E has a 90nm Prescott core. It has an L1 cache of 12KB + 16KB, and an L2 cache of 1MB. It supports SSE3, which the Northwood doesn't. Prescott review: http://snipurl.com/9vc6 Further Northwood / Prescott comparison: http://snipurl.com/9vc5 " What does serial ata/ ultra ata mean? " Ultra ATA / 33 / 66 / 100 / 133 and Serial ATA / 150 are the external speeds of your hard drive. http://www.webopedia.com/TERM/U/Ultra_ATA.html http://www.webopedia.com/TERM/S/Serial_ATA.html " What's the difference between single and dual channel memory?

How much better is ddr400 than ddr333? I already have 1gb pc2700 Kingston ValueRam. Would it be worth paying another $175+ for 1gb ddr400? Anything good or bad to say about any of these boards?

What does serial ata/ ultra ata mean? What's the difference between single and dual channel memory? What is raid for? Thanks for any answers you can give. Larger cache will be significantly faster, but CPU speed is only part of overall system performance. If you are not sure you need the larger cache, then you don't. SATA (serial ata) is a new, potentially faster interface for disk drives that is gradually replacing IDE, which goes by several names, including EIDE, PATA, and Ultra ATA. Right NOW, there is no performance gain by choosing SATA over IDE. (IDE is already faster than the fastest hard drives, so you gain nothing by upgrading to SATA) However, it would be a good idea to buy SATA drives anyway, if you have to purchase new drives. That way, they can more easily be recycled into your next system, if needed. There is NO difference between single and dual channel memory. NONE. The difference is in the mainboard chipset. Some mainboards can take two sticks of DDR RAM and use them as one stick that is twice as wide. If you have trouble grasping that concept, think of RAM like an Excel spreadsheet. Now double the number of columns, and you have dual channel. This allows information to be transferred to and from RAM faster, just like if a highway is widened from two lanes to four. But there is no difference in the memory. The difference is in the way the mainboard uses the EXACT SAME memory. But if you want to use dual channel memory, you should buy two sticks of RAM that are the same model number. They do NOT have to be matched pairs, though. You gotta watch out for that marketing gimmick. Some memory makers sell dual channel kits at a premium price over what two SINGLE sticks of RAM would cost. That is a ripoff, as there is NO difference in the memory itself. RAID usually refers to using two hard disk drives as one, to increase performance compared to a single hard disk drive. This is somewhat similar to dual channel memory, sometimes. You can do two different things with raid. You can speed up disk performance by using both drives at the same time, so that they are essentially one large, fast hard drive. This is what is usually referred to as "RAID". You can also make one drive an exact copy of the other one (for a real-time backup). That is also RAID, but a less popular use of RAID. Just like with dual channel memory, you will want similar hard drives (but not necessarily identically matched pairs) to use for raid. -Dave |

And the first kind of RAID you described is called RAID0. The second one is called RAID1 and again yes they do have to be a matched pair, as in same size and speed, not necessarily same manufacturer though, although this helps in performance. As for your reccomendation for SATA, there is a BIG difference in the performance of a SATA hard drive as opposed to a regular IDE hard drive. Please don't confuse this person with your ignorance. |

ABIT IS7-E AOPEN AX4SPE-UN GIGABYTE GA-8IPE1000-G INTEL BOXD865PERL MSI 865PE NEO2-V Regarding your question about the ram. Kingston valueRAM is one of the best brands of ram I've come across. It's easy to overclock (or not, your choice) and runs every bit as well as other brands. Unless you just really want to spend the extra money buying ddr400, I wouldn't. You won't see much of a performance boost out of the ddr400 as opposed to the ddr333 (unless you overclock the 333, which is sometimes easier than overclocking the 400. This is done by relaxing the ram timings, but if you don't know what you're doing, then I wouldn't. As for your question about the above boards you mentioned, the Abit is the best of those choices. I know many people who have those boards, and have nothing but good things to say about it. The MSI board is also very good. |

ABIT IS7-E AOPEN AX4SPE-UN GIGABYTE GA-8IPE1000-G INTEL BOXD865PERL MSI 865PE NEO2-V The AOpen is the best of the bunch, with the MSI board a close 2nd, and everything else a distant 4th. You're in a tough spot, as the RAM you have is good stuff, and it would not be worth it to upgrade to DDR400. BUT, the processor you need won't match perfectly with what you have. At the same time, I think it would be a waste of money for you to spend ~$200 for the RAM that you really need, as the performance difference won't be noticeable, other than a slight increase in numbers of some certain benchmarks. A good compromise might be to buy a gig of DDR400 to match an 800FSB processor, and then sell the gig of DDR333 on ebay. But even if you get a good price for your current RAM, you will still be out a good hundred bucks or so, for very little performance gain. Basically, you have a tough decision to make, and nobody here can help you with it, only offer their own opinions. There is no obvious RIGHT decision here. MY OPINION: Use the RAM you have. If you have extra money to spend, invest in a faster video card. For a gamer, you can't possibly spend too much on a video card. (!) But this will mean your mainboard will slightly UNDER-clock your RAM, if you choose a fast processor. A good choice of processor would be a 3.0E, 800FSB, 1M cache. But for that processor, there is no exact match of clock speed/divider that will allow the processor to run at 800FSB AND the RAM to run at 333. Most mainboards will run your RAM at ~320 to allow the processor to run at full speed 800FSB. But then again, you fork out the two hundred bucks for DDR400, and the increase in overall system speed won't be nearly enough to justify the extra two hundred bucks. IMHO -Dave |

though, although this helps in performance. As for your reccomendation for SATA, there is a BIG difference in the performance of a SATA hard drive as opposed to a regular IDE hard drive. Please don't confuse this person with your ignorance. No, you are confused. SATA has the potential to be faster, just like PCI Express has the potential to be faster than AGP. No doubt at some point in the future, SATA will kick IDE's butt, performance wise. But it hasn't happened yet. -Dave |

No doubt at some point in the future, SATA will kick IDE's butt, performance wise. But it hasn't happened yet. Most SATA HDs, with the exception of the WD Raptors, are IDE drives with only the interface electronics changed. They are subject to the exact same physical limitations (spindle speed, head performance, cache size) as their IDE predecessors. Therefore, their performance as SATA drives will not change from their IDE roots. OTOH, built-to-purpose SATA HDs -- the WD Raptors -- DO have significantly increased performance over IDE HDs. They are closer in performance to 10K RPM SCSI HDs. |

Yea I like the features on that Aopen board very much and the review I read said it was really good. The problem is that it says it supports ddr400, it doesn't say ddr333, which is why I asked if it was worth it to upgrade my ram. I was gonna ask if I could use my ddr333 ram in Aopen board, but I noticed that most of the boards I looked at listed both ddr333 and ddr400, whereas the Aopen only said ddr400, so I assume it doesn't support both like some other boards? MY OPINION: Use the RAM you have. If you have extra money to spend, invest in a faster video card. For a gamer, you can't possibly spend too much on a video card. (!) I already have a 9800pro. Thanks for the response it was very helpful. |
