  1. Hello, What is the pc specification. When buying memory there is always a risk that it may not work with the old modules. For this reason you should never mix different memory modules unless you know that the chips used on both are exactly the same. On the 939 CPU 3 modules will never work. Also when you buy new memory you should find a way to test them. The DFI board has a program called memtest, this is what you should use. Using your old sticks in the orange slots, do the following. GENIE BIOS Setting >DRAM Configuration..................Press Enter = New Menu FSB BUS Frequency....................200 LDT/FSB Frequency Ratio..............AUTO LDT BUS Transfer Width...............16 16 CPU/FSB Frequency Ratio..............AUTO PCI eXpress Frequency................100Mhz K8 Cool 'n' Quiet Support............Disable Cool 'n' Quiet MAX FID...............AUTO CPU VID StartUp Value................Startup CPU VID Control......................AUTO CPU VID Special Control..............AUTO LDT Voltage Control..................1.20 V Chip Set Voltage Control.............1.50 V DRAM Voltage Control.................2.70 V +0.3v if not 3.2v....................Disabled Run MemTest86+.......................Enabled GENIE BIOS Setting >DRAM Configuration DRAM Frequency Set (MHZ).............200 (DRAM/FSB:1/01) Command per clock (CPC)..............Disabled Cas latency (tCL)....................2.5 RAS to CAS delay (tRCD)..............4 Min RAS active time (tRAS)...........8 Row precharge time (tRP).............4 Row cycle time (tRC).................11 Row refresh cycle time(tRFC).........14 Row to Row delay (tRRD)..............2 Write recovery time (tWR)............3 Write to read delay (tWTR)...........AUTO Read to write delay (tRWT)...........AUTO Refresh period (tREF)................1560 Write CAS latency (tWCL).............N/A Odd Divisor Select...................Disabled DRAM Bank Interleave.................Enabled DQS Skew Control.....................Decrease DQS Skew Value.......................0 DRAM Drive Strength..................AUTO DRAM Data Drive Strength.............AUTO Max Async Latency....................6ns Dram Response........................Normal Read Preamble Time...................5ns Idle Cycle Limit.....................AUTO Dynamic Counter......................Enabled R/W Queue Bypass.....................AUTO Bypass Max...........................AUTO 32 Byte Granularity..................Disabled (4 bursts) Save and exit. If the pc boots, let memtest run for 1 pass. If all is ok, turn off. Insert the new modules in the yellow slots. Power the pc and see what happens. If it works memtest should be running. Let memtest run for 6 hours. (as long as possible). If you receive no errors then it is probably ok, try to go into windows.
  2. With your current settings but start at 166, 250FSB and x10. If it is stable just change the multiplier.
  3. Yes, if 250x10 works try 250x11 then try 250x12. < which = 3Ghz.
  4. Depends on how long you had it running at the higher voltage. There are side effects when doing so. You may find that it needs more voltage to run at the previous setting. And when lowering the OC you may find that it needs more voltage than previously. And in the most extreme cases, running at stock settings requires more voltage. That is the risk of overclocking and when possible you should try to keep the voltage as low as possible and keep everything cool.
  5. I haven't seen you here for a while. Happy x-mas, if you don't do x-mas happy new year. And if you do both, both
  6. Hello, Are all six jumper blocks on pins 1-2 or 2-3? (all up or all down).
  7. I wouldn't go past 1.45v. CPU, 50DC is a safe place to be. Now as it is, what happens if you lower the CPU multiplier to x10. Set the DRAM ratio to 166 5/6 Set the FSB to 250Mhz HT ratio to x4 And leave the rest? These still on? Max Async Latency 8ns Read Preamble Time 6ns
  8. Hello, Yes there will be a very small performance hit. Due to the extra capacity the memory controller needs more time to access the memory. "noticeably slow performance." We are talking nano seconds so there is no way that you will notice this. More memory is always an advantage especially in todays world.
  9. Just the board, CPU and memory. Any fans jerk when you press the power button? Plus what Wevsspot has suggested.
  10. Start at 200Mhz as this should be 100% stable. Then when you reach 250mhz (if you can) stop. Leave it at 250Mhz and go to x9, if stable x10 and so on. But now if it isn't stable at 200Mhz something is wrong. Do you have any other memory modules to test with? Up the voltage to 2.7v.
  11. Yeah only when clearing CMOS you must not. Something about the board, it stores more settings which when cleared (by removing the battery) may cause the board not to boot.
  12. It is not the same . The CPU has something called the base clock frequency, IE 200Mhz. When you change the FSB this is what you change and it makes the cpu core physically try to run faster. Lower the multiplier and slowly increase the FSB, see how far you get. If you successfully get to 250x8 with the memory on a 166 divider you are in a good position. Then increase the Multiplier to x9 if it works go to x10. When you get stuck the vcore voltage may need to increase. You can take it in small steps to 1.45v.
  13. Hello, Use a program like Everest to find out the memory timings. Then manually specify the timings in the BIOS. And use that as your starting point to start tweaking. http://www.lavalys.com/products/overview.p...3&ps=UE&lang=en
  14. I changed that post, you must never remove the battery on the Expert/Venus boards.
  15. Sorry for not getting back sooner. TRC...........07 change to 11 TRFC..........11 change to 14 And try running the memory as close as you can to 200Mhz (400DDR). Lower your multiplier (CPU ratio) to something such as x8. Dual core means it requires a lot more power and the memory controller/memory settings may be running low but the actual memory controller isn't. Should it fail start increasing the Vcore voltage and monitor the PWM and CPU temps. (What are these temps at the moment?)
  16. Hello, The winchester core will only run 4 double side modules at 333DDR and 2T command rate. And just using 2x1GB = DDR400 at 2T command rate Windows XP/any 32bit OS will not make use of 4GB, in fact you are wasting your time and money trying to run more than 2x1GB on such an OS. And on top of those issues DDR1 costs more than it should.
  17. Hello, If you can find some, a 2x1GB PC4000 kit would be the one to go for. OCZ have a PC3200 2x1gb XTC kit rated at 2-3-2-5. http://www.ocztechnology.com/products/memo...el_platinum_xtc This is a good one to get, if you are into overclocking it may be able to run at [email protected] G.skill ZX http://www.gskill.com/en/f1-3200phu2-2gzx.html or this http://www.pc-memory-upgrade.co.uk/new-pro...000-2gb-kit.asp All decent DDR1 kits are now rare.
  18. Hello, When using 4x512MB it can only run at 2T, this is due to the memory controller on the 939 CPU. It is a limitation that you cannot get around when using 4x512MB. Also when using 4x512MB the memory controller needs more time to be able to access the memory, therefore your overclocking settings that worked with 2x512MB will require adjusting. And in general you will lose a bit of performance but dont be put off by this. You may not be able to run the memory at 300Mhz. Does this help you?
  19. Try these. Max async latency = 8ns Dram response = normal Read Preamble = 5ns or 6ns
  20. Hello, Stop all your overclocking, Read this http://www.diy-street.com/forum/showthread.php?t=20823 You need to find out the following, 1, What is the Hypertransport BUS (HT link in 1.JPG) 2, What does the LDT ratio do 3, When you overclock the FSB what happens to the Hypertransport BUS When you can answer these questions you should know where you are going wrong. Obviously memory timings also play a part in a successful OC. The FSB also changes the memory speed.
  21. Hello, How hot does your PWM, and chipset get? What are your other memory timings like, if you could post them here.
  22. Set the memory voltage to 2.8v, GENIE BIOS Setting >DRAM Configuration DRAM Frequency Set (MHZ).............200 (DRAM/FSB:1/01) Command per clock (CPC)..............Disabled Cas latency (tCL)....................2 RAS to CAS delay (tRCD)..............2 Min RAS active time (tRAS)...........6 Row precharge time (tRP).............2 Row cycle time (tRC).................11 Row refresh cycle time(tRFC).........14 Row to Row delay (tRRD)..............2 Write recovery time (tWR)............3 Write to read delay (tWTR)...........AUTO Read to write delay (tRWT)...........AUTO Refresh period (tREF)................AUTO Write CAS latency (tWCL).............N/A Odd Divisor Select...................Disabled DRAM Bank Interleave.................Enabled DQS Skew Control.....................Decrease DQS Skew Value.......................0 DRAM Drive Strength..................AUTO DRAM Data Drive Strength.............AUTO Max Async Latency....................6ns Dram Response........................Normal Read Preamble Time...................5ns Idle Cycle Limit.....................x16 Dynamic Counter......................AUTO R/W Queue Bypass.....................AUTO Bypass Max...........................AUTO 32 Byte Granularity..................Disabled (4 bursts) Give that a try, but it probably wont work.
  23. Hello, If your memory is rated 3-4-3-8 You must do this, Cas latency (tCL)....................3 RAS to CAS delay (tRCD)..............4 < Min RAS active time (tRAS)...........8 Row precharge time (tRP).............3 < You mention the memory voltage changing back, it does this with BIOS v125 which is quite old. Does that also mean you have a winchester core CPU?
  24. I have seen such issues, when people remove the IHS from the CPU and a few times bent pins cause the cpu to stop working in dual channel mode. Very strange. If you can, test the CPU in another pc or borrow another cpu.
