  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
