CPU and Motherboard: PERFORMANCE OC Recommendations
CPU: AMD Athlon 64 FX53 (2.4GHz 1024K L2 cache)Motherboard: MSI K8N Neo2 (nForce3 Ultra)
Price: CPU - $811 shipped (Retail). Motherboard - $165 shipped
For Overclockers looking for the best performance possible, it would be tough to recommend anything other than the Athlon 64 FX53. The Athlon 64 is currently the fastest processor you can buy; the Dual-Channel Socket 939 is the top-performing A64 Socket, and the FX is the fastest 939 processor. The FX also has the distinction of being the only processor that is completely unlocked. That means that you can adjust multipliers both up and down, to obtain the highest possible speed at the fastest DDR400 memory timings, or to obtain the highest FSB that your high speed memory can run or your CPU can reach. Most FX53 that we have tested easily reach 2.6GHz at default voltage with air cooling, and some do even better. This pegs performance at a clock speed that we won't see in a retail CPU until late this year.
While the 3500+ (2.2GHz) can reach similar speeds, it is still multiplier locked at the top (lower multipliers can be selected though) and the cache is only half of what is found on FX53. The 3800+ runs at the same 2.4GHz with half the cache, but again, the regular Athlon 64 are top-locked, and the small price difference between FX53 and 3800+ makes it difficult to choose the 3800+ over the FX53.
What you get in the FX53 is the fastest stock performance currently available among desktop processors, and the ability to reach even higher. AMD does not call the FX series their Enthusiast CPU for nothing. There are no locks to hold you back and the real limit is what the .13 process can do with Athlon 64. Based on how very well the FX53 has performed in our tests in recent reviews, we can hardly wait to test the new 90nm process FX chips that should become available at the end of the year.
While they are just beginning to appear in the retail channel, the MSI K8N Neo2 stood out in our recent Socket 939 roundup as a top performer and earned the AnandTech Gold Editor's Choice. Perhaps even more important to an overclocker, the K8N Neo2 was the only board in the 939 roundup to match and actually edge ahead of the standout memory performance of the legendary Asus P4C800-E in our overclock tests. The K8N Neo2 actually reached a Clock Frequency of 290 (DDR580) with fast DDR550 memory that we used in our overclock tests. Wherever you can take the FX53, the K8N Neo2 will go - to the limits of your CPU or memory.
While the overclocker will likely turn off most everything when pushing boards to the limit, when the day is done and the system returns to a little more sedate levels, the K8N Neo2 will continue to impress with a full implementation of the features of the nForce3-250Gb/Ultra including fast on-chip LAN, any-drive RAID that allows IDE and SATA hard drives to be combined in RAID arrays, and an on-chip Firewall. The feature set compares well to any premium Socket 939 on the market and will not disappoint.
For the best overclocking experience, you can count on a working AGP/PCI lock with adjustments from 66 to 100, CPU multipliers from 4X to 20X, HyperTransport adjustments from 1GHz to 200MHz (5x-1x), and CPU frequencies from 200 - 300. You also get a full range of voltage adjustments - vCore to 1.85V, memory voltage to 2.85V, and vAGP to 1.85V. This is even a board for the beginning overclocker, since there are automatic overclocking selections in Core Cell that set everything for you. You just choose the % overclock from 1% to 11% and the board does the rest.
We have never tested a perfect board, and as much as we like the K8N Neo2, there are still areas for improvement. The CPU frequency range is really not wide enough for a board that does 290 at 1:1; we would prefer to see 350+ in that area. The greatest improvement that MSI could make is to provide finer adjustments for CPU ratios, providing 0.5X ratios like some of the competing boards. Last, there is no real voltage adjustment for HT or chipset voltage, and that would add to the flexibility. In the end, it's hard to complain about a board that does so much, so well. The MSI reached 290x9 (2610) with fast memory, and for those who prefer raising the ratio, 2652 was an easy 13x204. Since all of these were at near stock voltages, serious overclockers will find ways to get even more from an FX53 on the MSI K8N neo2.

Well I decided to try the EVGA card for 389 from www.buyxg.com Went to the site, lo and behold the card is stated there at 389. I go to buy it and it rings up 409. Ok, so I see it's backordered and I send them an e-mail basically asking them to honor the homepage. They essentially tell me that I don't know what I'm talking about and the page is now fixed. I don't think I'd recommend them in the future as an accurate price guideline. Granted Anandtech doesn't guarentee prices, but I think poor business practices should be addressed.PrinceGaz - Thursday, July 29, 2004 - link
Just a slight error in the article regarding the Mobile XP 2500+"However, the FSB speeds and multiplier are also a fortunate accident on the 2500+, since 11X is also the same multiplier as the top 3200+ Athlon XP. Since the 2500+ runs at 166 FSB, 3200+ performance is often as easy as setting the FSB to 200 from the default 166. Most, but not all, 2500+ can easily reach 3200+ speeds. The 2600+ mobile also looks even more promising as an overclocker, though we have not yet tested it. With specifications of the same 45 watt power consumption, a 12 multiplier, and 166FSB, it is hard not to be tempted when it is less than $10 more than a 2500+."
The desktop version of the 2500+ does run at 166*11 (1833 MHz), but the Mobile version has a 133FSB default. Thats not a problem because as you say in the article, they are unlocked so you can set the FSB and multiplier to whatever you like. But you will need to lower the multiplier with the Mobile 2500+ to run it as a 3200+.
The Mobile 2600+ is probably a much better choice because it has a much higher default speed than you'd expect,
Desktop 2500+ 166*11 = 1833 MHz
Desktop 2600+ 166*11.5 = 1917 MHz
Mobile 2500+ 133*14 = 1867 MHz (1.45V)
Mobile 2600+ 133*15 = 2000 MHz (1.45V)
the Mobile versions of both chips have a slightly higher clock speed than the desktop versions to compensate for the lower default FSB. In particular the Mobile 2600+ is a whole 133MHz faster than the Mobile 2500+ to compensate for the ever diminishing returns of higher multipliers.
For an overclocker that means the Mobile 2600+ is an unlocked chip that is guaranteed to run easily at 2GHz while still at 1.45V. That pretty much guarantees it will reach 2.3GHz, and maybe as much as 2.5GHz at the desktop 1.65V. And you can always give it a little extra juice if that isn't enough :)

#2 bluedarti did some research about a month ago on the synthetic diamond heatsinks and it seems they have been used for many decades (40+ years)."Swans" research was extremely helpful. i would like to know what material you are coating the diamonds on and also if you are infiltrating the diamonds with copper etc,(if you are makeing one you know what i mean). i have one ordered using tungsten and 6%cobalt as the base metal, 1mm to 1.5mm thick. i'm glad to hear someone else is playing around with this. btw, the specs that i looked at were 7x better than silver, using single crystal. also, what size are you using and are you using an existing product or are you starting from scratch? have fun.

I like the writting style and thought processes behind the review.. It definetly was the most fun, and most detailed one ive seen.BUT,
Your Recommendations are shaky at best. When you argued the 2500+ over the 2600+ for the mobile chip, it made sense, but the inclusion of the FX-53 over an Athlon64 just completely eludes me.. Id suggest you talk to some people on the forums before you do your next one, to doublecheck you have all of the current overclocking trends down. Oh, and a true overclocker would never even CONSIDER a Speeze heatsink.. If you want to talk about the article I can try to give you my opinion, you have my name in the forums just PM me.

I have to say that this is by far the best of ANY of the guides that you and Evan have put together for Anandtech, Wesley. Perhaps it's the inclusion of four system options (with prices for all four, even!), or maybe it's just that I'm an overclocker at heart? Anyway, I'm not too sure about the FX-53 on the performance end, as it's just way too expensive, but that's about my only complaint. You mention the 3500+, and for the price, I would think that's the way to go.I have to agree with the suggestion of just making suggestions for the five basic platforms, though. I mean, you already have done that, with the exception of the socket 754 system. Add in a motherboard (MSI K8N Neo Platinum?) and CPU (3200+ 1 MB?), and you're pretty much done.
Anyway, great job! I'm seriously looking at a socket 754 overclocking setup in the near future, unless someone can convince me that the extra $120 for the 3500+ over the 3200+ (not to mention the motherboard probably costing ~$40 more for S939) is worthwhile. Any takers, or should I just go with a 3200+? I won't be buying for at least another month, Wesley, so you can address my needs in your next OC guide! :)

MSI just sent the following reply to our request for information about when the K8N Neo2 would be available for purchase by our readers:"I am sorry for this kind of situation and inconvenience. My first shipment of K8N Neo2 will be this coming Tue. (Aug 3rd). Most on-line etailers (newegg, ziproomfly, .......) will post the board on Wed. or Thu to allow customers to buy it.
We will also modify the product page from "available soon" to "first week of AUG." http://www.msicomputer.com/product/p_spec.asp?mode..."

Great article as always. These are my favorite because it is exactly what I look to your website for the best of the hardware out. Key word out. The MSI board is not out and now had been delayed to somewhere around August 9. By August 9 the board will probably be delayed again. Why do you keep putting a board up that no one can get? The 6800s are hard to get but can be gotten . This just a suggestion. Still great article except board.Wesley Fink - Wednesday, July 28, 2004 - link
The Coolermaster CM stacker is not an all-Aluminum case, but a mixture of 1.0 mm steel plate for strength and Aluminum alloy. The description has been corrected in the article.Anemone - Wednesday, July 28, 2004 - link
Agreed Shinei...I'm looking at the 3700 EB (3-3-2-8) and then at the new 4000 Rev 2 (2.5-3-3-?) and curious how they compare. Had a chance to look over the new 4000 Rev 2 yet Wesley?
Loved this article totally - as well as the 939 reviews. OC'ing on the new 925X boards has a host of connected issues with pci-e and sata, so bye bye Intel...
Another great AT article for sure

T8000 has apparently never read any of the Socket 939 benchmarks AT did, or he'd know that the AFX's stomp out Intel at media encoding (along with just about everything else). Anyway, moving on from Trollville.I agree about the 3500+ being the better price/performance part over the FX53. Of course, I don't own one, so I can't comment on performance, but based on AT's results, it looks like a promising component...
