  1. ahh i see, thanks~ Even when i set in bios the cpu voltage to 1.45v, it shows up only 1.42v in bios. set at 1.475v shows up 1.44v. lol...
  2. I have set the CPU VID startup and VID control in bios at 1.40V In bios, it shows 1.40V In windows, CPU-Z = 1.376V ITE smartguardian = 1.37V Nvidia monitorview = 1.45V so... which one is correct?? Thank you~
  3. yii, how come some of my own replies in this thread are missing. I have setup my system yesterday, new Corsair DDR550 4x512mb were not able to run stable at anything above 220mhz at 1T @ 2.74v, very strange as compared to previously I was able to run up to 255mhz 1T @ 2.74v(only 1 pair at orange slot). I have yet to test them 1 by 1 to see if any of the RAM is faulty. Now running 2x1024mb Kingston, and the system is stable at 13.5 x 206mhz @1T. The reason i use half multiplier is because it crashed at 14x200 ... i have not much choice, the RAM is not stable at 2-3-2-6 1T above 210mhz. FX55 2600mhz 90nm has no better overclocking potential compared to my old FX55 130nm , both ceiling at about 2780mhz. I will stick to this 2x1024mb then~ the Corsair RAM will be used at my old P4 system.
  4. I just got my CPU claim. The replacement unit is 90nm (old one 130nm), yahoo~ I just got my RAM claim, Corsair 4000 no longer in stock so they give me 4400, sooooo lucky that they are the same model as my another pair. I have 4x512mb now. 2.5-4-4-8 at DDR 550 I have another pair, Kingston 2x1024mb 2-3-2-6 DDR 400 So if compare with same frequency, which one will offer best performance, 13 x 200.9 = 2612 @ CL2 1T or 9.5 x 275 = 2612 @ CL2.5 2T or 10.5 x 249 = 2614 @ CL2.5 1T ? I can use benchmark programs to test, but real application may be different from these benchmark result. Please assist to decide which RAM combination to use. Thank you~
  5. err, yeah that is the problem. The on-die memory controller is dead. RMA at AMD and the new unit shall reach me in next few days. T_T
  6. Slot 1 & 2 will not run in dual channel mode. only 1 & 3 or 2 & 4 will (same colour)
  7. My RAMs never boot in dual channel (1 pair). It boot in single channel (1 pair) but not stable with what ever setting. With single RAM setup, first yellow slot never boot. Orange slot boot and run perfectly. So now i can only run 1 piece of RAM, the other RAM rest in peace. Tested with RAMs at DFi, single sided 2x Kingston 256mb, boot dual channel. Corsair 3200C2PT cannot boot dual channel. Change the CPU solve everything... T_T
  8. Err? memory controller is something operate independently? But some RAMs did work dual channel on my CPU... T_T how come?
  9. WAHAHAHAHAHAHAHAHAHAHA, ****FX CPU****, WAHAHAHAHAHAHAHA I think you have exactly same problem as me. The reason is simple, CPU compatibility. I just opened up a thread before reading yours. wahahahahahahaha i have friend now wahahahahahahahahahahahahh..... NO CURE my friend, at the moment. I am waiting DFI taiwan's solution through the local DFI distributor. I think only a bios upgrade can save us (WIDE upgrade it will be, involve almost all DFI boards) Although yours is FX57, i guess our problems are similar. Before this i used 2x Corsair 512mb without problem too.
  10. Need help from those who have FX55 *****ONLY**** plus a DFI NF4 board that has been running over some times; and have access to many RAMs (from friends or other sources) My system will never boot in 1st yellow slot with single RAM, and will never boot dual channel with my RAMs. It boot single channel in slot 1&2, but very unstable in windows regardless of what setting i tried. Tested in DFI distributor place, it boots dual channel with certain RAMs only. Tested also on DFI Ultra D and CFX3200, no go. Finally, I changed a DFI Athlon 3000+ CPU, and all RAMs work perfectly now. Changed back my CPU and its dead again. If my CPU is faulty it wont work at all. Appreciate other FX55 (0.13) users to confirm this. Thanks.
  11. LOL ok. So the clarification shall be:- "DIMM 2&4 exceed normal specification", and not "DIMM 1&3 are of poor quality." They fulfill normal spec instead.
  12. LOL... ya, more RAM is better. tighter timing lose to more ram in real application. This thread is to point out that, why DFI says DIMM2/4 perform better than DIMM1/3, which make user confused that 2/4 is better than 1/3. I just found out my system problem yesterday at DFI distributor, which I write in another thread about unable to boot 1st slot and dual channel. So i can no more comment on this timing thing until DFI/AMD solved my problem.
  13. I think it is better for you to open a new topic about your problem. if you have 2 RAMs, put in same colour slots. yellow+yellow or orange+orange.
  14. err, I should change the word "Best RAM" to "Fastest RAM". 512mb module can has tighter timing compared to 1024mb module. i.e. 1.5-2-2-5
  15. All right, a breakthrough discovery was made today after I went to DFI distributor today. I brought along my board, CPU, 2 pairs of RAMs for them to test. The DFI distributor was nice enough to help troubleshoot my problem. They have carried out these steps:- 1) Tested and confirmed my problem was true with the items i have. 2) Opened up new DFI NF4 SLI-DR Expert to test, cannot boot dual channel. 3) Opened up new DFI NF4 Ultra-D to test, cannot boot dual channel. 4) Opened up new DFI CFX3200-DR to test, cannot boot dual channel. 5) Changed my RAM with their old Kingston RAM 2 x 256mb single sided, BOOT dual channel. RAM chip written "Kingston", but i think Kingston is not making own RAM chip. Before giving up, the distributor made a call to a "computer expert" to seek advice. That "expert" just say one thing, "the processor". When I heard that, I feel like, "What!? what to do with processor?? my processor is FX man..." Unwillingly, I change my CPU with DFI old Athlon 64 3000+ CPU to test. what's next? THE SYSTEM BOOT DUAL CHANNEL, WITH ALL TYPES OF RAM THROWN IN!!!!!!!!!!!! I was speechless when i saw that. When i changed back my processor, dual channel boot failed again. The distributor kept telling me that dont worry my processor was fine, was a good one...well if my cpu was damaged then i wont be able to use it all this while. The distributor said they will liase with DFI Taiwan engineering section as well as AMD to sort out the solution. DFI or AMD may directly contact me if needed. Personally i think this is not AMD FX problem, but more to mainboard compatibility problem. This is a really new discovery, the moderator may can make some comments about this in FAQ or something. Ohh ya there is one interesting thing during the test. The distributor tried a wierd way to put the RAM as follow:- CPU : My FX-55 Slot 1 : Value RAM Slot 2 : Value RAM Slot 3 : HyperX RAM Slot 4 : HyperX RAM Guess what? The system BOOT and printed DUAL CHANNEL, 3.6Gb RAM ... LOL... this shouldn't happen. I am now back at home running the system with single channel mode (2x HyperX). Unstable to run at rated 2326-1T stock voltage. Adjusted to 2336-1T at 2.8V at the moment. **** update ***** Single channel unstable. One by one RAM test, one of the HyperX RAM was found unstable at CL2 after overnight stress test. Jesus, what is wrong with Kingston, this is 3rd pair I changed from the shop, all because of one of the pair not stable at CL2.
  16. LOL... that is because your PROCESSOR is different from mine. "WHAT!!? %@$" i guess this is your first impression when you read it. Well I dont believe that too until just now. I will explain it in the next reply.
  17. DFI stressed that orange slot offer better compatibility with tight timing compared to yellow slot. It is written clearly at very first few front pages of the manual before introduction of the board. Q: How can I obtain good performance on an overclocked system? A: Insert two identical broad bandwidth memory in DIMM2 and DIMM4. (orange) Also in memory installation page, it writes:- "When modules are inserted in DIMM1 and DIMM3, the SPD must be 2T for better system stability. We recommend inserting DIMMs in DIMM2 and DIMM4." So the conclusion is, DIMM 2 & 4 offer better stability and performance than DIMM 1 & 3.
  18. As topic :confused: How can we fans get maximum out of it if 2 of the 4 RAM slots are of lower quality? Best RAMs are usually low capacity (MAX 512mb per piece) only...
  19. ah, thanks. lol Kingston is **not recommended** memory for DFI. aih, how come the Corsair C2PT wont work as well >_<;
  20. try go to nvidia to download nforce driver and install the IDE driver.
  21. All right, I went to the shop and they helped to do intensive testing. Finally found the problem:- 1) The board is not faulty. 2) The RAMs are not faulty. The shop opened up some of his shop's new Kingston Value RAM, 256, 512, 1024, will NEVER boot dual channel. He then opened up few pairs of new HyperX RAM, 512, 1024, and same thing happened. The shop opened up 2 of his new DFI board to test, same thing happened. The shop flashed all official bios from DFI website, no go. Finally, the shop used a pair of old Kingston RAM, holla, it BOOT dual channel!! We found out the RAM chip was different from those we tested earlier. So the conclusion is, Kingston RAM with Hynix chip will NEVER boot dual channel. Anyway we donno what type of chip is on HyperX... What about RAM from other manufacturer? The shop tested some and below was the result:- 1) TWINMOS value ram - Boot dual channel (non Hynix) 2) Transcend value ram - Boot dual channel (non Hynix) 3) Corsair XMS 3200 C2PT platinum - NEVER BOOT dual channel !!!!!!!!! (cant see chip type) That shop has only high performance RAM from Kingston and Corsair, and both will never boot dual channel. He suggested me to go straight to DFI distributor and demonstrate this problem, hopefully the distributor can solve it or, reflect it to DFI taiwan for another bios upgrade. I think this is important information for DFI fans, hopefully moderator will highlight this in FAQ or something.
  22. Ohh ya, i missed out this. Yes, they boot in slot 1 and 2 (yellow & orange), single channel mode.
  23. I have been using DFI NF4 Ultra-D for a year before, with Corsair 4400 C25PT. (having wierd problem, finally identified is RAM problem and now sent for claim) While waiting the claim (about 2 months) I changed to current system, wanna try on tight timing and thus bought 2x Kingston HiperX 3200 1Gb each. I also add on a Gigabyte i-RAM and bought 2x Kingston Value RAM 1Gb each for it. So the problem here is, with CMOS cleared and no other PCI rubbish installed:- with single RAM 1st slot (yellow) - NEVER boot on any RAM (HyperX or Value) 2nd slot (orange) - boot on all 4 RAMs. HyperX 2-3-2-6-1T also no problem. 3rd & 4th - never boot, of course. with dual channel, 1 pair 1st and 3rd (yellow) - NEVER boot on any pair (HyperX or Value) 2nd & 4th (Orange) - NEVER boot on any pair (HyperX or Value) with dual channel, 2 pairs NEVER boot Since i-RAM is very sensitive on defective RAM, I tested all RAMs on it and it was running fine. **confused** Appreciate any help T_T. Thank you.
  24. PLEASE READ CAREFULLY about that new bios before you flash that 04/06 bios. Check your bios chip version on mainboard!!! Check your bios chip version on mainboard!!! Check your bios chip version on mainboard!!! Did i say that 3 times? ohh well, I flashed that bios and kill my board a month ago, just because the 04/06 bios is for another version of bios chip. The bios chip version just different by xxxx004 or xxxx040 the 04/06 and 03/29 are identical, just different by the bios chip version.
  25. OMG... see what happen now, I take this RAM to other machine, clear cmos, and then start the PC. It runs without any problem at everything default !! passed Prime95. Jesus, what is wrong here? That DFI board specifically goes against my RAM? The board i tested was Intel 875P (200mhz)
