  1. OK having troubles with the IDE SW driver. Once I instaleld it from "Found new drivers" comand along with all the other Nf4 drivers the system BSOD's? I dropped th e speed to 533MHz which at leas gave me nough stabiity to Roll back throuhg Windows error boot up screen. It's working now but not very well and shouldn't I be using Nf4 drivers not rememnts of 590 drivers?
  2. Hi I'm new here. I just got a ULTAII-M2 from Newegg to replace my Asus M2N32-SLI which I had problems with after flashing to the infamous BIOS 903 to accomodate Opterons. I've had a few 50 board but kept hearing this baord was an exceptional overclocker and the few reviews Ive read stated it was the best AM2 board they ever tested. I just did a new build: ULTRAII Opteron 1212 BFG 8800GTX Ballistix Tracer 5300 2GB PCPower&Cooling TurboCool 1KW DD NIVIDIA 4101 H20 kit Windows XP Seagate 80GB Perpendicular Problem: I hit the power button the system began to run and the loudest continual Beep I ever heard comes from the board. I mean loud, of course I was siting in front of the thing as I used the manual power button. EDIT - One reason I've nick-named myself the Idiot Savant is because I'm so smart I'm boderline stupid. The PCIe 12V external power cables were not plugged into the BFG 8800GTX. I'm lucky the card or board wasn't damaged. It was only on for a second the first time and two the second time but seconds are to micr-electrnics what human years are to dog years.
  3. I have simple question. Why when AMD is enduring their worst design and production era are there no Socket-AM2 desktop enthusiast boards supporting the AM2 Opteron? The only boards running 590 chipset were produced by DFI. I ordered a 1218 I got for $300 Retail at the egg 9 months ago, it gets to my home and I'm so excited to plug into my trusty Asus M2N32-SLI dlx in which I'm running a 3800X2 at 10x300FSB without Vcore increase! The Opty 1218 arrives and I'm psyched I plug it in the Asus and no post? It took me One minute to remember I'm an Idiot Savant and two minutes to learn there were practically no mobos supporting Opterons except for a few DFI's and some with chipsets I'd rather not mention because not too many people want them for Gaming, Desktop or all purpose. With the option of buying another Socket-590 mobo which would have to remain in my test system I I sent chip back got a refund and when one of my my Leadtek 7950GX2's fried and I ordered a BFG 8800GTX, at that point I tried to forget about the AM2 Opteron and wait like everyone else, but as time went on this got stuck in my craw. Then about 4-months ago I decide to get the DFI 590-SLi and a Opteron 1212. As the combo is in route I learn that Asus just released the 903 BIOS supporting AM2 Opterons? Once the stuff arrives I try my 3800X2 in the DFI and she won't boot to 300FSB without Vcore? Then I install the AM2 Opteron 1212 and the same thing. I then install the Opteron 1212 in my Asus M2N32-SLi with the new BIOS 903 and immediately boot to 350FSB which posts, then drop to 320FSB which remains stable for almost all benchmarks without any Vcore increase! The Socket 939 Opteron rage made AMD some money but more importantly introduced the Opteron to Overclocker's the world over. When AMD launched Socket AM2 why had no mobo makers supplied Opteron BIOS's and listed the AM2 Opteron as "Officially SUpported"? If I were a conspiracy theorist I'd say AM2 board makers were threatened by Intel they would loose right to C2D support in their existing i975X chipset baords and any future chipsets such as 965 if they "Officially or un-officially" supported AMD's ACE in the Hole, AM2 Opterons. Of course it's probably not a coincidence DFI (very small) and only recently Asus (now the largest mobo maker) were the only two to provide BIOS supporting these potentially overclocking animals. Asus has leverage given their aquisition of Gigabyte and ownership of other companies like Asrock, DFI possibly slipped under the radar or were allowed to prevent the look of a conspiracy. Whatever the case, for my reviews I use two systems, one AMD and One Intel always trying to keep them updated with what the "largest" majority of PC-Enthusiasts are using, and I can tell you the Opteron and 590 combo still trounce Intel in many areas, and we would do well to remember almost all of C2D performance is based on it's ability to overclock. Run em head to head and AMD AM2 Opteron crushes C2D by over 50% in memory bandwith and does a dam good job at default speeds in 3D yes I said 3D if you use the right memory at the right speed and latencies.
  4. Truth is with Latency much is made of numbers without understanding how they work. This quote is my Bible for understanding latencies. Lets dicuss 32-bit systems with DDR-SDRAM DDR2 is only slightly different, but this easier to understand... Current systems read memory in 32-bit chunks, comprising four 8-bit bytes. CAS latency specifies the number of clock cycles required before the first byte can be read. After that first byte is read, the remaining bytes are read without latency, in one clock cycle each. For example, CL3 memory delivers the first byte after three clock cycles and the other three bytes in one clock cycle each. This memory timing is designated 3-1-1-1 and indicates that six clock cycles (3+1+1+1) are needed to read all four bytes. CL2 memory uses a 2-1-1-1 memory timing, and therefore reads all four bytes in five clock cycles (2+1+1+1). Similarly, CL1 memory uses a 1-1-1-1 memory timing and requires only four clock cycles to complete the read. On that basis, one might conclude that CL2 memory is 16.7% faster than CL3 memory and CL1 memory is 33.3% faster than CL3, which is a substantial difference. In fact, that differential holds only for single 32-bit reads, whereas most reads are streaming. During streaming reads, each 32-bit read after the first is performed without latency. As the number of streamed 32-bit reads per access increases, the relative significance of the CAS latency overhead incurred for the first byte diminishes. For example, compare a streaming 32-byte read (eight sequential 32-bit reads) with CL3 versus CL2 versus CL1 memory. With CL3 memory, the first 32-bit read requires six clock cycles. Each of the following seven 32-bit reads does not incur the CAS latency penalty, and so requires only four clock cycles. The full 32-byte read therefore requires a total of 6 + (7*4) or 34 clock cycles. With CL2 memory, the first 32-bit read requires five clock cycles, and each of the following seven 32-bit reads again requires only four clock cycles, for a total of 33 clock cycles. With CL1 memory, all eight 32-bit reads require four clock cycles each, for a total of 32 clock cycles. In this (very realistic) example, CL2 memory is actually only 2.9% faster (1/34) than CL3 memory, and CL1 memory is only 5.9% (2/34) faster than CL3. Hope this helps
  5. Depending on the IC's these are using, DDR2-800 may be better simply because you can run CL3-3-3-12 just beyond 800MHz however the faster memory may use Elipida or newer Micron D9's which don't holf tight timings well. I've seen some real improvementts between CL4-4-4-12 at 100MHz which the less expesnive Patriot DDR2-800Mhz will do easily on Gaming benchmarks compared to 1100MHz runing 5-5-5-12 on the other "faster" chips. This link may tell you which memory uses which chips and that may help. Just remember with Intel systems that latency isn't going to matter as much as top speed. Here's a MadOnion2001SE benchmark using 800MHz Micron IC's aka PC2-6400;
