Asus A8V Deluxe: Overclocking and Stress Testing
FSB Overclocking Results
| Front Side Bus Overclocking Testbed | ||
| Processor: | Athlon 64 FX53 Socket 939 2.4GHz |
|
| CPU Voltage: | 1.5V (default) | |
| Cooling: | Thermaltake Silent Boost K8 | |
| Power Supply: | Antec TruePower 430W | |
| Maximum OC: (Standard Ratios) |
204 x 13 2652MHz (+10.5%) |
|
| Maximum FSB: (Lower Ratio) |
289x9 (2601) at 1:1 Memory | |
The A8V Deluxe Revision 2 has come a long way from the first revision that didn't even have an AGP/PCI lock. Revision 2 is in a virtual dead heat with our top-performing MSI K8N Neo2 at 289 x9 with our Shikatronics DDR550 memory. The A8V also matched the highest OC with this FX53 at 204x13 at default voltage. This overclocking performance is as good as we are accustomed to seeing on the best nForce3 Ultra boards, and can only be called superb when achieved with the VIA K8T800 PRO, which is not always the best overclocker. To achieve this overclock level, we needed to reduce the base Hyper Transport frequency to 800.
Memory Stress Test Results:
The memory stress test measures the ability of the the Asus A8V Deluxe to operate at its officially supported memory frequency (400MHz DDR) at the best performing memory timings our Mushkin PC3500 Level 2 or OCZ PC3500 Platinum Ltd Modules will support. Memory stress testing was conducted by running RAM at 400MHz with 2 DIMM slots operating in Dual-Channel mode. The memory configuration of the Asus is the more standard setup with slots 1 and 3 are the first Dual Channel.| Stable DDR400 Timings - 2 DIMMs (2/4 DIMMs - 1 Dual-Channel Bank) |
|
| Clock Speed: | 200MHz |
| Timing Mode: | N/A |
| CAS Latency: | 2.0 |
| Bank Interleave: | Enabled |
| RAS to CAS Delay: | 3T |
| RAS Precharge: | 10T* |
| Precharge Delay: | 2T |
| Command Rate: | 1T |
The Asus K8V Deluxe Rev.2 was completely stable with 2 dimms in Dual-Channel at the settings of 2-2-3-10 at 2.6V default voltage with 1T command rate. This is very slightly slower than the timings than worked on other Socket 939 boards. While we could run the majority of benchmarks at 2-2-2 timings, there were a few that were not completely stable until we increased Ras-to-Cas delay to 3. It should be noted that the BH5 memory modules we used for testing are no longer available for purchase, but we have not yet established our standard memory for future testing. We will be using a new standard memory in future motherboard tests.
As we first found in our latest Socket 754 roundup, the Command Rate is very important for top performance on a VIA chipset motherboard. The best performance is at a Command Rate of 1T, and the Asus A8V was completely stable at a 1T setting with 2 dimms. We set 'Bank Interleave' to 'Enabled' in the BIOS, and Sandra 2004 SP2 reported a 2-way Bank Interleave was being used by the memory controller. With an on-CPU memory controller with Athlon 64, this is not as important a setting as it is on with chipset-based memory controllers.
Filling all four available memory slots is more strenuous on the memory subsystem than testing 2 DIMMs on a motherboard.
| Stable DDR400 Timings - 4 DIMMs (4/4 DIMMs - 2 Dual-Channel Banks) |
|
| Clock Speed: | 200MHz |
| Timing Mode: | N/A |
| CAS Latency: | 2.0 |
| Bank Interleave: | Enabled |
| RAS to CAS Delay: | 2T |
| RAS Precharge: | 10T* |
| Precharge Delay: | 2T |
| Command Rate: | 2T |
We see a very interesting result with all 4 dimm banks filled. The Asus A8V was able to run with all 4 dimm slots at more aggressive 2-2-2-10 settings than the 2-2-3-10 required for 2 dimms. Please keep in mind, though, that the Command Rate must be reduced to 2T when filling both Dual Channels, and the memory is actually a bit slower even though the other timings are slightly faster. The A8V Deluxe is also very picky about the settings that are used with 4 dimms in the 'Enable 2T' option in BIOS. If an Auto setting is used with 4 dimms the board tries to set 1T and single channel memory at a lower memory speed. If 'Auto' is selected and memory timings are forced to DDR400 the board would not boot. With 4 dimms, you will need to set the 2T option to 'Enable 2T' for proper Dual-Channel operation at DDR400.

#50 (RyanVM)...A quick check at pricewatch shows you CAN'T BUY IT (the 3.4EE S775, nor the 3.6E 775). Nobody even advertises the S775 for sale at top speeds. The 3.6EE has not even been released yet, and the 3.4EE can't be bought (775's I'm talking). Of course anand could get some engineering sample as before (Intel Confidential written on all pics I've seen ANYWHERE), but are we comparing something I probably won't be able to get for 2 months or more? Prescott 3.4 anyone? Took 3+ months for these to FINALLY show up as a product I can buy (and they were announced Feb2nd I think, reviewers got samples march 21st or so))...I'd call that a bit of an early review, just kills sales for the competitor as people wait for Intel (nvidia 6800 ultra anyone?). If you CAN buy it, show it to me. Otherwise for all intents and purposes the 3.4EE S775 chip doesn't exist. Is that a bit clearer for you? Did you bother to read where I said only 10 places are even selling the 3.4EE for S478? Paper launches and whats AVAILABLE are two completely different things. AMD can probably show some benchmarks of their dual core shortly, but who cares if I can't buy it until mid 2005 (or later)?The 6800 Ultra has been out for what like 2 months. I still can't buy that either (nor sell it, which is pissing my customers off..."why don't you have it, I've been waiting 2 months"...blah). The prescott 3.4E just finally started shipping last week for crying out loud (15th I think it was..strangely that press release is GONE everywhere..hmmm). I think reviewers should either completely disregard products that can't be bought or at least dedicate a good paragraph of two to the track record of the last release, and how you'll probably be waiting for months for the one 'we're reviewing today'. I'd say the same about ATI's, but at least one place is selling its best for $999 (ROFLMAO...IN STOCK though..heh).
Note that Dell's 3.6E isn't expected until December! http://www.theinquirer.net/?article=17347 (5 months away?) I can see telling me about something I might be able to get next week, or maybe 2 weeks, but we're talking 3-5 month paper launches here. Do my statements make more sense to you now? Maybe I'm just tired of customers chewing my butt as if I could do something about it.

#34, the ECC support question is less obvious than you might think.The specs for socket 939 boards I have checked either say "non-ECC", or don't say either way, except I learned today that the MSI K8N Neo2 Platinum does say it supports ECC.
The general lack of support is surprising given the Athlon64's on-board memory controller. AMD's specs do say the 939 CPUs support ECC, but that does not obviously imply that all motherboards do.
Some official specs that explicitly say non-ECC:
ASUS AV8 Deluxe:

#49 & #50 - There is indeed a Socket 775 3.4EE, but as Anand showed in his 775 launch article the 3.6 is actually a faster CPU. you can check his results at http://www.anandtech.com/cpuchipsets/showdoc.aspx?...Our motherboard testing showed the same thing, which is why we did not even bother to test with the 3.4EE. It is true there a few benchmarks where you pick up a few points with the 3.4EE, but the difference is generally small and the 3.6 is faster overall. Of course the 3.4EE is in addition a lot more expensive than the 3.6. Given the 3.4EE cost and lack of standout performance, we felt the fastest 3.6 compared to the fastest FX53 was the fairest comparison at the top.
It would have possibly made sense to include Socket 754 data for the 3400+ for instance, but that is a different socket and could not be tested in these boards. Those benchmarks are available in the 2nd Generation 754 motherboard motherboard roundup at http://www.anandtech.com/mb/showdoc.aspx?i=2063. Since those benchmarks were done only a few weeks ago we didn't repeat them, but we could include the K8N Neo (754) running a 3400+ for referenc in future charts.
We never had an FX53 754 in the motherboard lab so that direct comparison can't be done here. However, Derek did exactly that comparison in his 939 launch review at http://www.anandtech.com/cpuchipsets/showdoc.aspx?...

#49: "There is NO P4EE for S775"There very much is a Socket775 P4EE at 3.4GHz. Did you read any reviews at all before spouting that off?

#22 TrogdorJWFirst of all, ONLY 1 place shows the 560 P4 "IN STOCK" and only 2 others as PRE-ORDER. Is it even fair to say this CPU exists? The 3.6EE doesn't exist yet either in any socket. I would have liked to see more cpu's like you, but the 3800+ would be the only real need here, as it is the exact price range as the 560 (but a A643000+ and P4 3.0 would be cool for the poor). However, when looking at the situation as a whole who'd pass on 64bit, TOTALLY UNLOCKED chip, and domination for around $90-100? If you're spending $700 on a CPU wouldn't you spend $788 to dominate, and completely obliterate once 64bit gets going (did I mention the totally unlocked part?)? If that $100 really means that much the 3800+ w/64bit is much better (not to mention gaming domination now). On another note, you can't expect Anandtech to compare a CPU that won't even go into S775 yet. There is NO P4EE for S775. How could they possibly throw in one of those? Even for S478 there are only 10 places selling them (3.4EE, again no 3.6EE exists) let alone how many in stock. Test a dead end 3.4EE S478? Better include a caveat then that states it's about to be EOL.
Why test Xvid when its not a real standard? Divx is barely getting going in DVD players, getting Xvid on them too (right now) is a shot at a dart board. I'd prefer they drop these tests totally and show a DVD9-DVD5 rip as I think people are more interested in that. I don't know anyone encoding to divx when dvd burners are $60. Who actually watches movies on their PC (not many)? Who wants to fight to get X revision of Y codec to work on their setop DVD player? I think many more people are joining netflix (etc) and DVD9-5'ing it. Or just downloading what someone else already did (9-5) in the newsgroups. Downloading from the newsgroups (what divx was made for pretty much) is pointless when you have to try to get [x version, at y resolution and z codec and xyz audio bitrate (heh, ran out of letters)] to work on your dvd player. The only way to get them to work 100% is buying a player and doing your own rips that you prove WORK on your player (nobody trading on the web does vids to your dvd players specs mind you). But why would you go divx/xvid at all if you're doing this yourself (and not sharing them) with retail dvds? Wouldn't you dvd9-5 it instead and end all compatibility BS? If you're talking quality, divx/xvid etc is NOT DVD Quality. No matter how you encode it. Burn a DVD and get it over with :)
RE: 64bits breaking 4gb. That's not what its about for us Desktop users. It's about the extra registers etc. We are probably 3-5yrs from 6-8GB on desktops (as norm). On desktops you've seen anands (etc) tests with 2GB or under but getting the EXTRA registers benefits. In a server review I'd expect 8GB or more tested. In a desktop review 4GB will make no difference in anything they'd probably throw at this review. Also, if you can afford GB dimms, you'll buy a server BECAUSE you're trying to break the barrier for X app that you use and have 16 slots probably for smaller sized dimms (at 1/2 the cost). Desktops have no more than 4GB support in ANY board on either side. We are only after the OTHER benefits of 64bit. The extra registers can be used with just a GB of memory. I'm not against having 4GB in my machine, but I don't see how it would change any of these tests. Just 2GB in one test setup could show us if anything would happen, no need for 4gb just yet.
I'd also like to see more games thrown at these machines. Use fraps to toss in more game types that don't have benching built-in. Painkiller, Perimeter, Ground Control 2, City of Heroes,Battlecry3 etc. CPU/Motherboard tests should look more like the videocard tests. On top of that, aren't we all downloading something in say Xnews/Agent etc while playing some game? How does that affect FPS? Pick a game and test the same group like that. Saturate your cable connection by firing up an easynews download or something, and benchmark a game. I'd think this would show NForce3 and Intel's chipsets at a MAJOR advantage as the Ethernet is NOT PCI. I'd bet tons of people download while playing games (online or not). Life sucks on PCI in this case.
One more comment/question. Where is the driver that scored 80+ in DRV and DX and dominated the rest of the workstation tests, even aquamark etc in this review: http://www.anandtech.com/mb/showdoc.aspx?i=2036&am...
We're talking 20-40% improvements and that was on a 5950 vs. this reviews 6800ultra. Seems I'd really want that performance for FREE. Where's that driver? 88 to 57 in DRV? SHEESH. How'd they do that? Where can we get it? I expected workstation domination on nvidia boards here.

Silly me on the MSI lan - new board using the NF3 250 LAN, right design, I didn't read carefully.My bad
Anemone - Wednesday, July 21, 2004 - link
I like them being interested in overclocking and speed :)Curious of Asus will put out a NF3 ultra board. Curious why MSI didn't use the NF3 Lan - since its better and lower in cpu useage.
Great review!
