  1. I've seen and heard some contradictory information on this topic so I thought it would be best to share my experience. If you have an NF4 Ultra-D motherboard the system will only post in the following configuration. Jumpers normal --------------- 16x top slot .............. (16x electrical) 16x bottom slot .......... (2x electrical) NOTE: A DFI NF4 Ultra-D motherboard WILL NOT post with an Areca card in top or bottom 16x slots if the jumpers are set to SLI mode. Now with that said, if you have an SLI-D or SLI-DR motherboard with an Areca card in the top slot, you can successfully post when the board jumpers ARE configured in SLI mode. Jumpers SLI --------------- 16x top slot .............. (8x electrical) 16x bottom slot .......... (8x electrical) It is possible to hardware mod your Ultra-D to an SLI-D motherboard. Thanks to Exroadie detailing this information, if you perform this hardware mod your motherboard will become an SLI-D. You will then be able to successfully post with an Areca card in the top slot with jumpers set to SLI mode. Picture Tutorial - Mod the Ultra-D to SLI-D Picture Tutorial http://www.diy-street.com/forum/showthread.php?t=10736 Now what's the benefit of using an Areca card in the top slot with jumpers set to SLI mode? Assuming you didn't perform the SLI mod, in normal mode (16x top/2x bottom) on an Ultra-D motherboard, the bottom 16x slot can only run at 2x electrical. However, an Areca card can only run at 8x/4x/1x electrical. So basically, the 2x electrical slot is reduced to 1x speed and thus bandwidth of your card/slot is severely reduced. The second benefit from using an Areca card in the top slot is reducing temperatures of the card. There is insufficient airflow if you run a dual slot video card in the top 16x slot and a controller card in the bottom 16x slot. The video card will emit lots of heat that transfers to the controller card and it will increase temperatures of the controller card by up to 10 degrees Celsius. Not only will a top 16x slot video card bottom 16x slot controller card configuration bring the operating temperatures dangerously close to Areca's specified limit, but it can also reduce the life of the hardware. If you have an Ultra-D motherboard, I suggest you mod it to an SLI-D. Then change jumpers to SLI mode and run the card in the top slot. HTH
  2. I went ahead and gave this SLi mod a try when I removed a Thermalright HR-05 SLi chipset heatsink to lap it. The mod was pretty straightforward when following the instructions and using an exacto knife, but I suggest anyone attempting this mod have a steady hand and be patient if necessary. My NF4 Ultra-D board that had some protective dot of goo adhesive applied on top of the contact points so it took a little longer slowly scraping away until i could hear metal to metal contact. A can of compressed air really helps in blowing away the goo to clear up the surface for good contact. I taped off the trace with some scotch tape and used a circuit writer pen to close the circuit. Then I used a hair drier on low setting to cure the silver. After assembly, cleared the bios, reassembled the box, and applied power. Everything worked fine on first boot. Overall this was a really easy mod although it requires some patience so you don't damage the chipset. Thanks ExRoadie.
  3. I'm aware of aging capacitors, but I don't think you read the 78 page thread either. There was a widespread engineering defect with Ballistix where the RAM would degrade and become unstable over time. It may or may not be a contributing factor with this user's experience, but it is a REAL problem that has been documented. Also, despite stability problems, Memtest would not show any signs of failure until the sticks were on their deathbed.
  4. Maybe you missed the 78 page thread about how Crucial released large quantities of defective Ballisitix DDR PC4000 RAM into the retail channel, but refused to acknowledge high failure rates? http://www.diy-street.com/forum/showthread.php?t=6719 Look for my posts in the thread, I originally built this system with Ballistix and experienced nothing by headaches from after the first month trying to troubleshoot system instability at stock speeds. Eventually, after seven months and several RMA I finally tossed the Ballistix and replaced with OCZ RAM. The problems disappeared. A couple of my later replies: http://www.diy-street.com/forum/showpost.p...&postcount=1188 http://www.diy-street.com/forum/showpost.p...&postcount=1218 http://www.diy-street.com/forum/showpost.p...&postcount=1219
  5. This is true, I realize that as an enthusiast I recognize certain flaws in products that the average consumer would not see nor would they even care about. This is also why companies like emachines stay in business, or why wal-mart is able to sell through cheap computers (like those linux systems pre-installed with Ubuntu - and this does not speak poorly of Ubuntu). AMD should strive to target this market, but at the same time AMD needs the server market (high performance, low power consumption) because these are the sales that generate the most revenue. The enthusiast market is a byproduct of advances targeted towards the server market, but it still generates high revenue turnover, because AMD can price these processors high. The margins aren't as high when you're targeting price conscious consumers.
  6. Not enough anger, but other than that I think there are valid points about short/long term market strategy, pricing, and the general nature of the price conscious consumer. Where I do disagree is about the financial solvency of AMD. By acquiring ATi, AMD took on huge amounts of debt. Contrast this debt with AMD's short term prospects by failing to deliver Phenom on time with performance and lower power consumption stats that were hyped as being able to beat competitive products from Intel. If anyone has monitored AMD's stock the past five months it has plunged from over $20 share to under $10. Intel is fighting a war of attrition, but AMD is also making huge blunders that are significantly leading towards its own demise. AMD did need a chipset of its own so it could compete with Intel selling complete systems to OEM systems integrators like Dell, HP, and Supermicro. However, AMD also needed Phenom to be a huge success out of the gates with performance and lower power consumption so that AMD could sell their chips at a higher price point and put a large dent in all those liabilities that were acquired from ATi during their merger. The chips did not come out in time in Q1-Q2 '07, and when they finally were released in Q4 '07, the chips were released broken with erratum in L3 cache, that required AMD to recall all Barcelona Opteron chips. Phenom is effected too, but why were these chips not recalled like Barcelona processors? Because it would have cost too much money. AMD's solution? Release a BIOS patch and hope the general consumer doesn't notice any instability or performance loss in Phenom processors. This is also overlooking that Hector and AMD PR spent the better part of '06-'07 hyping Barcelona and Phenom as the chip that would outperform Core2Duo/Quad , but would also offer significant power savings because AMD's True QuadCore architecture allowed for independently clocked cores for on demand processing power. I haven't personally tested a Barcelona or Phenom chip, but from every review I've read, real world statistics do not match the hype. It's a chip that uses more power and offers less performance. By all means it appears Phenom is to AMD what Prescott was to Intel; overhyped and under delivered. Similarly, ATi has failed to produce a GPU product at lower price points than Nvidia with higher performance and lower power consumption the past two generations. The one shining beacon of hope for AMD right now is of course the 790 generation chipset and it uses only 7-9 watts of power. Compare this to Nvidia's 780 generation chipset which requires around 30 watts of power and a huge heatsink with active cooling for sufficient dissipation of heat. This development should help AMD secure more OEM contracts for server, desktop, and laptop markets. Don't take this criticism the wrong way, with the exception of a stability issue due to the infamous crucial ballistix DDR500 I've been happy with my AMD system for the past couple of years. I hope AMD can fix these problems and survive, but their short term outlook is rather bleak.
  7. Came across this thread while searching google.. http://www.pcmoddingmy.com/forum/index.php...9&mode=threaded Plenty of pics covering the mod. The only thing that could be done better IMO is to use scotch tape to ensure a nice and straight trace path without leaving excess conductive material.
  8. Just to update thread... After some discussion with Angry, I went ahead and took the plunge on a Corsair 620HX. Installed the unit in the second week of December in combination with a DFI NF4 Ultra-D. No stability issues have been encountered that can be attributed with the Corsair unit in this build configuration. Sig updated...
  9. Hi Dirty, Yes, being able to use the 2nd PCI-E 16x slot was a concern of mine from the start. I don't plan to use the 2nd slot for SLi, but rather for a PCI-E RAID card which requires 8x electrical signaling. I haven't kept up on the ability to mod the NF4 Ultra chipset, but last I remember Nvidia was taking measures to try and stop this through forceware drivers. The main problem with using the HR-05-SLI in a top mounted configuration is that there could be some clearance issues with different HSF. Some of the larger HSF like older XP-120 or Zalman 9000 will have clearance issues with a top mounted HR-05-SLI. The Thermalright Ultra-120 extreme may also have clearance issues, I'm not sure. Personally, for my application it's overkill. I don't think I'd need a HSF that large for an older AMD dual core, maybe if it was a newer Intel Quad Core. The 7000B keeps temperatures at around 34-39c at idle, which is fine for me until the HSF indicates failure and requires replacement. As far as the Antec 900, I could not say, I run a rather large tower case which uses 4x120mm fans with plenty of airflow. I'll take a look at some pictures of the Antec 900 if I can in the next couple of days, but really that's not the best way to find clearance information out. It's much better to find someone who's already done the experimentation for you and has the configuration that you're interested in. I'm not sure about the Ultra-120 extreme, it's huge so there may be clearance issues. =/ As far as clearance between a top mounted HR-05-SLI and a video card in the top slot, there is approximately, 1/4 inch clearance. The HR-05-SLI itself is I want to say 3/4 inch deep. Depending on the size and physical dimensions of the cpu HSF you may be able to top mount a HR-03 GT, but I think that would only be possible with certain square HSF. I'd say it's pretty obvious you definitely could not fit the HR-03 GT piping and surface area between the video card and the HR-05-SLI. The HR-03 GT looks much too large and the cooling fins are angled in a way that would not avoid contact. The 8800GTS, 8800 Ultra or other variations which use a dual slot cooler do not leave much clearance between the first card and the location of the 2nd PCI-E slot. There's only like a 1/4 inch clearance approximately, maybe a little more or less. I don't think you could fit a fan on a top mounted HR-03 GT and clear most cpu HSF. There would be clearance issues. You wouldn't be able to get direct cooling, but you may be successful keeping temperatures somewhat ok with indirect cooling from the cpu HSF or even from a 120mm case fan if it has a clear and unobstructed wind tunnel. This all depends though on the HR-03 GT's ability to efficiently dissipate heat from the cooling fins. Personally, I have no experience with the HR-03 GT so I can comment on this. I don't have Ultra-120 eXtreme atm unfortunately. I may end up building a new rig in a couple of months when the Intel Penryn processors come out and at that point I may consider a Ultra-120 eXtreme. I also don't really feel like tearing my case apart again either. It wouldn't be as bad just pulling the motherboard this time as opposed to stripping a chassis bare, but I think I've had my fill of playing around at this point. Also one thing to note. The spring clips will secure the HR-05-SLI but the chipset does sag slightly when the motherboard is mounted vertically. As someone in the thread previously mentioned, for better temperatures it may be worth it to secure the HR-05-SLI to the motherboard and chipset with some nuts/bolts with rubber washers between the bolt/motherboard (backside) and the nut/motherboard (frontside). I would have done this, but unfortunately the local hardware stores did not sell rubber washers that small. You may have similar issues finding rubber washers that small. I would not install the nut/bolt without it though or you risk damaging the motherboard or potentially creating an electrical hazard. No problem, glad I could help. In my case, for my own sanity, I got tired of listening to my VC-RE screaming (fan was dying) and it was time to replace it.
  10. Even if the PCI-E slot is only running x8, your video card will never use all the bandwidth. Video cards couldn't even saturate AGP 8x
  11. If the bios on your Ultra-D is 3/10/2005 it probably doesn't support dual core X2 cpu as those cpu weren't released until June of 2005. Use the 6/23 official bios. It will work fine with Athlon X2 4400 and OCZ memory.
  12. re-seat your video card, make sure it is in the slot. Use a thumb on the top corner of the card and press down with some firm pressure. Not so much to break the card or the motherboard but enough to make sure it's seated. Sometimes the bracket on the card is tight and won't easily allow a video card to make contact with PCI-E pins. If the video card isn't seated you will receive 3 lit LEDs, no video signal, and fans will spin at high RPM. Often times it's the most simple things that are overlooked.
  13. Anyone have recommendations on where to buy 4/40 rubber or plastic washers? The local hardware stores don't carry anything that small.
  14. In the event anyone was curious, a HR-05 SLi WILL fit without clearance issues in the top mounted position with a Zalman 7000 HSF installed on DFI NF4 Ultra-D/SLi-D/SLi-DR motherboards. The photo below is slightly deceiving, but installed this way you have about 1/4 inch clearance above a video card when the video card is inserted.
  15. The information from the last few pages of the Seasonic incompatibility thread contained some conflicting information. There were a few posts suggesting that the issue would be fixed in a 3rd revision. However, a page or two later there was an official response from Seasonic posted that more or less refused to acknowledge any problem, nor was any statement made about a fix. The reason I posted this question was due to a conversation I had with a member of Corsair's tech support a few days ago. The support tech more or less conveyed that the 620HX would not work with the Ultra-D motherboard, even though the NF4 Ultra-D was compliant with ATX 2.01 and that they'd had some issues with that board. I figured I would post here to try and receive some clarification since I'd seen a few people with the DFI NF4 Ultra-D and Corsair 620HX configuration.
