  1. PLEASE IGNORE MY LAST POST. I WASN'T THINKING. It's too late, I need to go to bed.
  2. Ok, so I have the FSB at 265MHz and the memory divider set to 180MHz / 9:10. This should give a memory speed of 238.5 right? But it doesn't Both CPUz and clockgen report that the memory speed is at 227.16MHz. Am I missing something? I am using the latest official 4/06 bios.
  3. I can't get the 2048-4000PTs that I have prime95 stable... I've put the CPU multiplier down to 6x, Vmem = 2.8V, Vcpu = 1.35 x 1.144% = 1.5444 1T timing, 1:1 mem dividor, 4x HTT multiplier, All over voltages are at stock, and the memory settings are: Command Per Clock (CPC)....................... - Enabled CAS Latency Control (Tcl)..................... - 3 RAS# to CAS# delay (Trcd)..................... - 4 Min RAS# active time (Tras)................... - 10 Row precharge time (Trp)...................... - 4 Row Cycle time (Trc).......................... - 14 Bus Clocks Row refresh cyc time (Trfc)................... - 20 Bus Clocks Row to Row delay (Trrd)....................... - 02 Bus Clocks Write recovery time (Twr)..................... - 03 Bus Clocks Write to Read delay (Twtr).................... - 02 Bus Clocks Read to Write delay (Trwt).................... - 03 Bus Clocks Refresh Period (Tref)......................... - Auto DRAM Bank Interleave.......................... - Enabled DQS Skew Control.............................. - Auto DQS Skew Value................................ - 0 DRAM Drive Strength........................... - 08 DRAM Data Drive Strength...................... - 04 Max Async Latency............................. - Auto DRAM Response Time............................ - Fast Read Preamble Time............................ - Auto IdleCycle Limit............................... - 256 Cycles Dynamic Counter............................... - Disable R/W Queue Bypass.............................. - 16 x Bypass Max.................................... - 07 x 32 Byte Granularity........................... - Disable(4 Bursts) These timings should be pretty relaxed but I can only get prime95 stable (tested for 3 hours) up to FSB of 243MHz... A LONG WAY OFF 250MHz. Adding more voltage to memory doesn't help. Does anyone know what the Tref should be for these dimms? 7.8us??? 15.6us??? Also, what should the drive strength and data drive strength settings be for these dims? Someone please help, I've been trying for a while here. Thanks, Jonathan
  4. Loose timmings can only help stability. The fact that dropping the multiplier from 12x 200 to 11x200 without chaning HTT speed helped, would indicate that the ram is not the problem. I'm guessing it's either the CPU or PSU. Of course I would hope it's the latter. For now I'll just have to run the CPU under stock because I have a EE thesis due in 2 weeks and I can't afford to not have a working computer for simulations. Thanks for your help guys.
  5. update: Underclocking the CPU seems to help. I pulled the multiplier back down to 11x (200) and put the HTT ratio on 4x. The restart issue goes away... I'm going to run some prime 95 + 3DMark loops and see what happens. Not sure what this would mean. Could still be the PSU.
  6. Sorrento, I'm using higher than rated latencies at 200MHz. As you know, the ram is rated to 250MHz at faster latencies than this. I'll play around with the timmings but I'm not sure that that is the problem. In addition, the stability on memtest and prime 95 support that the memory is fine. blick, the CPU was OC for about 4 months on CPU VID 1.5. The temps NEVER got above 51 Celcius. They would usually run around 48 load and 42 idle. I really hope that I haven't burned out the chip. This would be my first. I'm usually pretty careful. madgravity34, thanks for the responce. It's interesting that you say that. I'll try taking stuff out and seeing what happens. I'll keep you guys posted. Thanks so much for the help.
  7. Ok, so I'm experienced OCer and I'm doing my masters in EE so while I'm not by any means an expert, I usually have a fairly good idea what I'm doing with these sorts of things... I'm this case I don't have any idea what’s going on. I know the following description is long but please bear with me. Bottom line: ON STOCK I'm getting blue screens plus other strange side effects. A few weeks ago I was running at 245 x 11 without problems. Then the blue screens started happening so I dropped it all back but I still get them at stock. I can't seem to find a pattern for the blue screens, they just happen randomly (load or idle). Also, when I restart the computer sometimes it will just hang. The fans spin up but they stay high and the computer doesn't beep. It requires a restart and then the computer usually post fine. I'm Prime 95 stable for 4+ hours (I haven't had enough time to let it run longer but I'm sure it would). Also I ran Memtest for 3 hours today without problems. My CPU temps are 48 Celsius under prime 95 (both cores) + 3D Mark 06 looping in the background (51 Celsius at 245x11)... Which is a little higher than I would like, but I find the 7800s and the 4800+ run pretty hot on the same cooling loop... and silence is important to me (since my computer is in my bedroom) so the res. fans aren't running very hard. BIOS settings are: CPU VID 1.3V Dram Voltage 2.9V CPU: 200 x 12 HTT ratio: 5x (increasing the CPU voltage doesn't help...) My BIOS memory settings are: TCL 3 TRP 4 TRCD 9 Trc 11 Trfc 15 Trrd 4 Twr 3 Twtr 2 Trwt 4 Twlc AUTO Tref 3120 cycles Bank Interleave Enabled Async Latency 7.0 ns Idle Cycle Limit 16 cycles The PSU voltages are 11.83V on 12V rail, 3.21V on 3.3V rail and 4.99V on 5V rail in Smartguardian under load. Also, I'm running Windows XP x64. I just did a reformat and reinstalled everything (I thought maybe the NTFS file system was currupt). My thoughts are to the power supply because of the random nature of these blue screens. How would I know if it was the power supply? If not that then maybe the memory heat sinks on the video cards aren't very good. They're the ozc ones with some thermal tape. I would use thermal epoxy but I want to have the option to remove them in the future. But, would over heating video card memory cause random blue screens?? I would have though vid artifacts first. If anyone has any experience with this sort of thing (on this board) then please let me know.
  8. thanks, I've never seen the MHz drop, I guess it must have a fairly high thermal threshold before it starts to kick in.
  9. Ok, in the 7 months I've had this board and have been overcloking, I've never noticed that this option is in the bios. Is this basically turning on Cool and Quiet? What is it? Should I leave it at 50%?
  10. i just tried a memory stick of a friend of mine, which I know works, so it's definitelly not the memory. My next guess is the motherboard. Dam... I guess I need to send this MB back. Has anyone had to RMA a board with DFI? Is the process long?
  11. yes. I unplugged the computer, took out the battery, changed the jumper, waited 30 minutes, put the jumper back, put the battery back in and then turned the computer back on... Didn't help.
  12. yeah, the memory is in the top orange slot. I've tried both sticks in all combinations, both dual channel and single stick. I've disconnected everything and then connected components trying to see if it will turn on and off again. I took of the CPU water block and took out the CPU just to see if there was any hidden water dammage that I couldn't see (of course there wasn't... I leak tested it for 24 hours). I took out the CPU to check for bent pins... none. I put the waterblock back on. I took out the video cards and the sound card to see if they were causing the problem, but it still wouldn't post past three lights. I've tried taking some of the power jumpers out (ie the FDD and the motex MB connectors) but that didn't help. I'm completely out of ideas. Has anyone had problems getting this OCZ 4000 VX memory to post?? Thanks, Jonathan
  13. thanks for the quick responce. THANK GOD its no the CPU. This is a little dubious though, I never touched the ram. I wonder if the memory controller on the CPU is stuffed... Then again, I might just be being overly pessimistic. I'm the meantime I will try to hunt done some sticks of RAM and try those. I've sometimes had troubles with these VX sticks. Often if I haven't set the Dram voltage to +0.4 V above the default value in the bios then it sometimes wont turn on. However, I've never had it stay off continuously like this.... Anyone have any ideas?
  14. ok, I've had this build for a number of months now and everything has been working up until this point. Yesterday I installed a water cooling setup in my existing build. I've leak tested it for 12 hours and THERE ARE NO LEAKS. I've got the CPU and the two graphics cards cooled, one with a swiftech storm and the other with two danger den blocks. Anyway, now the computer wont post. The Ram light and the power lights come on. When I turn on the computer the first diagnostic LED goes off. But then it hangs there just beeping at me. The FDD Led flickers on and off. I've cleared the CMOS, I'm now only using one ram stick in the top orange slot. I've periodically taken everything out and it doesn't change anything. Does anyone know what might be going on? It says in the manual that the 2nd diagnostic LED is to indicate that a CPU was found. Does this mean that when it TURNS OFF the CPU has been found or what? Or is it not recognising the RAM (which is supposed to be the next light. HELP!! I'm worried I've destroyed my CPU so a quick responce would be great. I guess I might have knocked off a MB component sometime, but I can't remember evern knocking it. I'd rather it be the $200 MB rather than the $820 CPU.
  15. where is that thermal throttling setting in the forceware drivers. Do you need rivatuner to get to it? Cheers, Jonno
  16. ohh and I tried turning off the read cacheing in the device manager but it makes no difference. It's wierd though, there are two instances of the same controller. Is this what you guys have?
  17. ok, so I'm getting HORRIBLE scores. I'm getting 43MB/s with bursts of 120MB/S. I'm running two WD raptors 74G a raid 0 array. I'm overclocking and my settings are: 10 x 264, 3x HTT multi., 1T, 1:1 ram, 2,2,2,6, and pci-e at stock. Why am I getting such low scores??? Please help. Thanks
  18. this is long... but bare with me. ok, so I want lots of memory bandwidth (3DMark05 LOVES the bandwidth) so I'm running my CPU at 10x multiplier and I want to find my highest FSB / HTT overclock at this speed. So I seem to be hitting this limit of 264MHz which seems ok. Prime95 is stable for 6+ hours with two threads of it running simultaneously. However, Memtest fails! So my first guess is that it's a memory problem. So I lower my multiplier to 8x and up my memory voltage to 3.5V... No good. So I eventually raise my CPU from 1.40 to 1.475 volts (big jump) and all of a sudden memtest is stable. Not a memory problem but a CPU problem? This doesn't make much sence since a blend test in prime95 is ok AND I've run the CPU at faster speeds using higher multipliers. I've been able to get 2676 = 12 x 223 vs 2640 x 10. So my best guess is that the on chip memory controller must be failing at 264MHz HTT (ok at 263) while the rest of the CPU can go faster. Is this normal? Has anyone else found that the on chip memory controller is the limiting factor in their overclock?? I thought that the ALU and the internal cache were the biggest problems at high speed. This makes me believe that the new revision E mem-controllers aren't very good at overclocking.
  19. ohh, I just noticed you have all 4 of your dimms slots filled (2GB). YOU HAVE TO HAVE 2T MEMORY COMMAND. There isn't any way past this. Even the new revision E cores have to have the 2T setting. The new cores do support DDR400 instead of DDR333, but still have the 2T limitation. This will affect your bandwidth in Sandra, but not much in real world applications. Thats the price you pay for 2GB of memory. I haven't made that sacrifice yet.
  20. ok, so I'm also running a 4800+ on a DFI NF4 - SLI DR... I've been pretty happy about its over clocking so far. I did own a FX – 53 130nm part that didn’t clock as well as the 4800+ even though they have the same stock CPU speed. Here's what I've been getting… I'm not going to overclock much since I don't want to go past 1.4V for now (I just don't see any point... it's fast enough), so these are REALLY week over clocks. 1.45 or even 1.5 I don't think would be pushing it. I'm using a Thermalright SI-120 CPU heat sink and my temps are 38 - 40 under load and 33 idle. Anything up to 48 should be fine (though not ideal) for the 4800+ and therefore I feel that I could get at least 2720 with enough voltage while still keeping in temp ranges. Highest 12x OC @ 1.4V CPU 12 x 221 = 2652 at 4x HTT, 1:1 memory, 3.3V memory, memory latencies 2, 2, 2, 5 Highest 11x OC @ 1.4V CPU 11 x 240 = 2640 at 4x HTT, 1:1 memory, 3.3V memory, memory latencies 2, 2, 2, 6 Highest 12x OC @ 1.4V CPU 10 x 264 = 2640 at 4x HTT, 1:1 memory, 3.4V memory, memory latencies 2, 3, 3, 7 These are all with 100% stability in prime95 (running both cores at once and 200MB for each thread). I found that the limiting factor in ALL these overclocks was the voltage. If I went up to 1.425 in each case I would get at least 30 - 40 more MHz out of the CPU. But for now, I'd rather not. Of course the 10x OC is the fastest since it gives the highest mem bandwidth (+10% over 12x OC), which real world applications seem to favor over just +/- 5% CPU speeds. It seems like your results aren't too bad. These high end chips never OC to the same percentages as the lower end chips. A note about the OS: I found that my overclocks were better after I did a OS reinstall. I had to anyway because I wanted to add another raptor to my raid0 array, and therefore I need to start from scratch. There really shouldn't be any reason for it, so I don't know why. Maybe the fresh install helped with stability. DON’T INSTALL THE AMD DRIVERS! There has been some talk around forums that they help with speeds, but in my experience they only cause more problems… Last time I installed them I got strange stutters in Counter Strike and other apps. The “fix” that supposedly fixes these stutters DIDN’T work for me. The fresh install helped this problem. What are your idle and load temps? What voltages are you putting across the mem and the chipset?
  21. anyone know where you can get these in the US?
  22. I'm now using a new x-fi sound card so I want to know how do you disable the Karajan Audio. I can't see the settings in the bios. Also, I want to disable the Silicon Image Sil 3114. I can't find that either. Every board I have owned has had bios features to disable such things, but I can't for the life of me seem to find it on this board. I'm running the latest official bios release. and here are my specs... eVGA e-Geforce 7800 GTX KO video card Enermax Noisetaker 600W OCZ EL DDR PC-4000 Dual Channel Gold VX (voltage extreme) AMD Athlon 64 X2 4800+ CPU 2 X Western Digital 8MB buffer, 74GB Raptor DFI LANParty nForce4 SLI-DR Lian-Li PC-V1200 Plus case modified with window Thermalright SI-120 CPU heatsink and Panaflo (Panasonic) 120mm M speed HydroWave fan Dell UltraSharp 2405FPW 24-inch Wide Aspect Flat Panel LCD Monitor IBM Thinkvision L190 19" LCD Monitor Sound Blaster X-Fi Fatal1ty FPS Logitech Z-5500 digital 5:1 speaker system
  23. Hey guys. Just bought a new 4800+ and I must say I love it. I could never recommend the FX57... the smoothness of the overall computing experiance is awsome. Anyway, thats the topic for another thread. I have 1GB now and I was wondering if I have to take the 2T hit when moving up to 2GB. I know with my old FX53 I had to, which really hurt my memory bandwidth... So much so, I sold the extra sticks and stuck (sorry about the pun) with 1GB. I've heard rumors but does anyone know for sure if they've fixed the memory controllers in the new X2s?
