Hi Lance, my ambient is 30c and i'm running at 1.45v + 10% or 1.57v in bios. At 2610mhz, it need around 1.52v to boot into Windows but i have not tested prime stability at this voltage. It has been around 8hrs since this morning's fluke and dual prime is running fine. I still don't understand why i got the error though. System has morning blues??

Thank you guys for your opinions. I guess weighing the pros and cons, removing the IHS doesn't seems to be a great idea afterall. I still need w/c because this X2 is Hot (55-60c at load) and i will like to cool my vga card and overall quietness.

I woke up today and ran Dual Prime(large ffts) on the same 290 x 9, 1:1 but it crashed within 30mins. This was stable for 12 hours yesterday... :confused: Reboot, checked all settings are correct and running again now. I hope the error was a fluke.

lol your bad haha :shake: Guess i have to seriously consider before putting the knife onto my 4400.

Wow ElDuderino, you have a very nice setup! :nod: I'm thinking of using dual 3 x 120mm rads in my w/c setup with Storm, MCP655, MCW55. Hope this can help me hit 2700mhz stable if not some more. I'm also praying i don't have a poor core that can only do 2610 stable. By the way, did you remove your IHS?

Hi dfx, thanks for the links. I'm now 10 hours dual prime(large ffts) stable at 290 x 9, 1:1. However HTT 300 will cause one Prime to give an error. (the same 0.4 but 0.5 error...) Using multipliers won't help as well. I guess it's my core 0 that has heat problems or can't go higher because it's always the one that has error when HTT is 300. My load temps at 1.45v + 110% is 55-60c. Do you think it will be a good idea to strip the IHS and put this under a Swiftech Storm?

Hi Lance, thanks for the encouragement. Mine is setup in a corner of my living room which has been designated as a testing area before it moves into my room haha. I have now backoff to CPU 2610mhz and Ram 580mhz. (HTT 290 x 9, 1:1) This has been running dual prime for nearly 4 hours and i hope it can continue to 8 hours or more so i can have at least a stable overclock. Sure hope it works or i'm going crazy. Also i was planning to put a good watercooling setup on this system but now i'm not entirely sure how the w/c will help me other than quietness... Anyway i guess i still need the w/c since my full loads temps are pretty high, 53-60c. Thanks again man!

I just tried increasing multiplier to 9. CPU is 2655ghz and ram 590mhz. (HTT 295,1:1) Both settings were found to be the highest stable cpu and ram clocks but when they are put together, it wouldn't pass Dual Prime.... I always get the same error within 1 hour of priming. (rounding should be 0.4 but given return was 0.5...) Can someone please advise me what could be wrong?? Really appreciate your help!

I have increase Tras to 7, Trc to 12 and Trfc to 14. This is now 12 hours Dual Prime stable.(large ffts) I hope when i increase multiplier to 9 to 2655ghz which is my safest CPU overclock, everything will run fine.

Sorry for the misunderstanding and forgetting to include this information. When i test the rams at HTT 295(where memtest is stable but Prime is not), the divider and CPC is, 200 Dram Frequency 1:1 Enable CPC

Hi bigzorro, thanks for the suggestion. I will try prime blend and probably only do Memtest when all Prime tests are stable.

Hi Boppo, thanks for your advise. I will try to increase TRAS and report back. For drive strength, i have tried 3,5,7 in memtest and all works fine but not Prime. Will try this as well. DFI is starting to become a love and hate kind of thing...

Hi ElDuderino, this is the first time i'm using a AMD cpu and DFI mobo. May i know what divider would you suggest?

I have been overclocking and tweaking my new X2 system for the past week but without success to make it stable. I'm sleeping at 3am everyday for the past week and this is making me crazy... :sad: In case anyone will like to know, my definition of 100% stable for 24/7 usage is at least 12 hours Prime95(run 2 copies, large ffts), 100 passes of Memtest #5 & #8, at least 8 hours HCI Memtest, 3dmark and games. First off, i started using the startup settings provided by Rgone in the stickys. Stock CPU and Ram speed. Dual Primed for 12hrs and no errors. http://www.dfi-street.com/forum/showthread.php?t=21248 Next, i tried overclocking and found my max CPU clock is 2655 using the below settings. Again, primed for 12hours with no errors. Average temps are, CPU : 55-60c (i know this is high but i'm planning to remove IHS and put on a good w/c setup after getting this thing stable) PWMIC : 48c Northbridge : 46c a. HTT = 295 a1. LTD/FSB = X3.0 a2. CPU/FSB Frequency Ratio = 9 a3. PCI EX Frequency = 100 a4. Cpu Startup VID = 1.45 Volts. a5. CPU VID 1.45 Volts. a6. CPU VID Special Control = 110% a7. LTD voltage = 1.4 Volts. a8. Chipset Voltage = 1.8 Volts. a9. Dram Voltage = 2.9 Volts. DRAM CONFIGURATION a1. 100 Dram Frequency 1:2 (the lowest multiplier) a2.

(tried both and primed for 12hours each time, both setting works for me) a16. DQS Skew Control = INCREASE a17. DQS Skew Value = 0 (zero) a18. Dram Drive Strength= Level 6 a19. Dram Data Drive Strength= Level 4 a20. MAX ASYNCH LATENCY = 7X a21. READ PREAMBLE= 5X a22. IDLE CYLCE= 256 cycles a23. DYNAMIC Counter= Disabled a24. R/W Que Bypass = 16x a25. ByPass Max 7X a26. 32 Byte Granularity = Disable 8 Bursts. Now that i have my max CPU at 295HTT, i set out to enhance my ram settings hoping to make it stable at HTT 295 and 300. (i'm not really looking to oc ram at the moment, just getting it to work stable at rated 600mhz will be nice) a. HTT = 295 a1. LTD/FSB = X3.0 a2. CPU/FSB Frequency Ratio = 7 (underclocking the CPU speed) a3. PCI EX Frequency = 100 a4. Cpu Startup VID = 1.45 Volts. a5. CPU VID 1.45 Volts. a6. CPU VID Special Control = 110% a7. LTD voltage = 1.4 Volts. a8. Chipset Voltage = 1.8 Volts. a9. Dram Voltage = 2.9 Volts. I used the ram settings as suggested for Gskill TCCDs in XS forums. Only changed Trcd to 4 because 3 will not work at all. (many users in XS also had to change to 4) http://www.xtremesystems.org/forums/showthread.php?t=57317 200 Dram Frequency 1:1 Enable CPC Vddr: 2.7v Tcl: 2.5 Trcd: 4 Tras: 6 Trp: 3 Trc: 9 Trfc: 12 Trrd: 2 Twr: 2 Twrt: 2 Trwt: 3 Tref: 3072 (200MHz 3.9us) Twcl: 1 Bank int.: Enable Skew control: 255 + Drive strength: 7 Data strength: I used Auto (or 2) *** why don't i see any option # 4 for this setting in both bios 623-3 and 704-2bta?? Max. Async: 7ns Read Preamble: 5ns Idle Cycle: AUTO Dyn. Counter: Enable R/W Bypass: 16x Bypass Max: 7x 32Bit Gran.: Disable This setting works great and i passed Memtest #5 and # 8, both 25 passes each. Then i ran HCI Memtest for 8 hours, 4000%+ completed with 0 errors. But my problem is when i tried to run Dual Prime(large ffts) with this supposely stable ram settings, my Prime will only run for 1 to 4 hours and give an error. The error i get is rounding should be 0.4 but given return was 0.5. I have tried lowering(7), increasing multiplier(8,9) and it does not help. I have tried vdimm 2.7 - 2.9 and it's the same. Am i right that if i get an error that is so close, ie. 0.5 instead of 0.4, i'm already quite close to attaining 100% stable? I will greatly appreciate any advise by the experts here to make my system stable!!

Have you tried the non-boot way of clearing bios and/or flashing to 704-2BTA? These have helped my system to be stable at stock speeds when even bios 623-3 is not stable. Do you also have your rams in the orange slots? Well at least for me, the yellow slots are very unstable but the orange helps to give much more stability.
