Here's some answers... some duplicate what others have already said so just take it as verification. All are IMO and if you prove me wrong, well, like they say, winning an argument on the internet is like winning at the special olympics...

PIB CPUs (Processor In a Box, AKA "Retail Box") enjoy a 3 year AMD warranty to the end user. OEM CPUs have a 1 year AMD warranty to the company who purchased them from AMD. Newegg may be large enough to purchase direct, but most companies purchase from distributors, which purchase direct or as surplus from other distributors or from large OEMs. However it works, just know that you as an end user only has as long a warranty as the retailer you are purchasing from is willing to warranty it. Most (but not all) online vendors warranty CPUs for 15-30 days from date of purchase.

Both motherboards are NFORCE4, which is good. The manufacturers are
ECS and Biostar, which is bad.

Not all terrible, though this particular Biostar board has a less than stellar record. The Biostar claim to fame is the "fake" AGP slot. You may (or may not) be able to reuse your old AGP card while saving up for a PCI-E card. The slot, AFAIK, is just running your AGP card on a PCI slot with a fraction of the bandwidth, so performance will be impacted. AFAIK only the Asrock Dual-SATA board using the ULi chipset had "true" AGP as well as PCI-E. I didn't read up too much on the bad reviews for the Biostar, but some of them may be for compatibility issues with AGP cards.

The ECS board looks to be the Nforce 4 Ultra chipset version of the ECS NFORCE4-A939. That board... wasn't bad. I used it in my main system (used daily) for a half year and never had any real issue beyond the known USB lockup - use a high speed USB 2.0 device and experience lockups. I just used a PCI USB 2.0 card that I already had laying about. I don't know if this board suffers from this problem. There are things I don't like about this board, such as the placement of the chipset (too close to video card IMO) and the use of a hook/loop retension for chipset HSF instead of the more common push-pin. This board is likely nicely overclockable. I had good results with the NFORCE4-A939 and someone reports 290MHz HTT on this board. Yes, nice overclocks with ECS boards :Q though I only tested at highest multiplier and don't know if the board can go insane with 300+. Still, with a 11x multiplier you'll hit the limits of the CPU well before the limits of this board.

My choice, unless hampered by an AGP card, would be the ECS.

From all your cpu/mobo combo posts and reviews.... Anand's lucky you aren't interested in starting your OWN tech site! :)

Thanks for all the continuing education!

LOL, you should see my garage... full of computer stuff, but not as full as back when I lived in CA.

i wish i did this instead of the S754 system i bit a month ago....now i'm about to bite 200 after tax on that XFX 7600GT when the pciE versions are like 120-130

Heads up from the customer comments:
THe only major con with this chip, which is a HUGE one is the 1600 mhz HT bus, instead of the 2000 MHZ HT bus that all other VENICE Cores have. The HT bus difference = roughly a 15-20% noticeable hit in FPS in most games.

I'm jumping in though, serves my needs just fine. :thumbsup: thx op

NOTE: This ECS is a PCI-e board.

There is absolutely no performance difference between 1600 HTT and 2000. AMD probably released these chips specifically so socket 939 motherboards could be made with nforce 4 chipsets that wouldnt run at 2000mhz.

Glad to hear this since mine is on the way... :) but why is there no performance difference? Isn't AMD's HTT (somewhat) analagous to Intel's FSB, which affect throughput platform-wide?

The Nforce4-4x can "only" run at 1600MHz, also there were older Nforce3 chipsets like that as well, IIRC (150 series).

I set up one of these combos today, with the free ECS motherboard. It works great. I overlocked the cpu to 2.5 Ghz without breaking a sweat (I also bought an Artic Freezer 64 Pro along with it). My first attempt to set the FSB to 220 Mhz didn't work, so I lowered the starting memory speed to 166 Mhz and tried again and then everything was fine. I'm very happy to be able to get an overlock of 2.5 Ghz sao easily. Idle temp is 34C. I think I could overclock higher, will try in a minute.

Just overlocked to 2.6 Ghz (using ClockGen software) and things are good so far. I have to say that the included ECS motherboard is a pretty good overclocker. It can and will overlock well with the right settings.

Running your memory at 166 on this board doesn't limit the overall speed? I have a gig of pc2700 ram that I would love to put to use in a budget system like this, but I was thinking PC3200 would be the minimum for a system like this.

Well, if your PC2700 is a matched pair, then you'd be running in dual channel mode. Even not, such a setup will be a reasonable performer - probably wringing more performance out of your existing RAM than any other platform.

The other thing is that when overclocking, you'd have to lower RAM speed because when you raise HTT, the RAM speeds will go back up.

I have PC3200 memory, but to overclock the system I need to lower it to 166 MMhz (PC2700) speeds. The memory speed then goes up as I increase the FSB. I have the FSB set to 236, which raises the memory speed to 180-something MHz (I'm not at the system now, so don't know for sure). Since I have my memory "underclocked" I can maintain tight timings, so system performance is very good. Athlon 64s were never starved too much for memory speed - the cpu speed increase far outweighs the slightly lower memory speed.

I did not see a way to adjust the voltage in the BIOS (I only looked briefly) but I can easily adjust it using ClockGen software. I was able to hit 2.6 Ghz on stock voltage.

PC2700 RAM would work fine in this system, but you'd have to lower it to 133 Mhz if you overclock, since raising the FSB will raise the memory, perhaps above what it can do. By lowering to to 133 Mhz in the BIOS, the memory speed will approach its rated 166 Mhz speed as you overclock.

For a "cheapie" motherboard, getting the cpu to 2.6 Ghz is quite nice.

I added a second stick of RAM (a cheapo 1 GB Kingston stick with slower timings than my 512 MB Crucial Ballistix that was already there) and the system wouldn't boot. I reset things and it now boots, but the memory divider was set to 22, so my RAM runs at 100 MHz! I can easily overclock to 2.6 Ghz, putting the memory at 118 Mhz. This means that my memory speed is less than PC2100.

My Super PI calculation times are 10% longer than when I had a single faster memory stick, running at higher speed with faster timings. I guess that's what I get by having cheap mismatched memory sticks. Overall, the system is still very fast. I'm going to see if I can get my memory speed up a little, though...

Overall, the system has been extremely stable, though. No problems running Prime95 overnight @ 2.6 Ghz.

The combo is now $99 with an ECS motherboard!

Free shipping, too.

Wow! That's a really nice deal. I have my cheapo, mismatched memory sticks running at better speeds now, and am quite pleased. I should mention that the ECS motherbaord has both cpu and memory voltage adjustments, so really is a decent overclocking board.

With the new lower price, its like getting the heatsink for free. I recommend the Arctic Freezer 64, for around $25 if you plan to overclock.

Similar weekly combo specials at fry's weekly. If you have a frys near you check the weeklys. Both very hot deals. I'm still running my $69 frys combo special 2 years now. The thing is unstoppable.

The Biostar nforce4 is also avail in the combo, it even has AGP and PCIExpress, though i head the AGP bridge is pretty iffy. Good if you want to chance your old AGP on it.

In for 3. Very curious to see how well the ECS board overclocks. I had reasonably good results with the NFORCE4-A939 board, which is pretty much the same board but with the non-Ultra version of the chipset. One report of this board doing 290MHz HTT.
