  1. Thanks Mar...tomorrow I'll tweak a little bit more with some of your settings. I appreciate it! EDIT: Messed around with the settings for an hour or so. No change in the overclock. I max out at 2700MHz, and even then prime isn't stable on one core for more than 10-12 minutes. So, i'm back down to 2650MHz for now. I will play around with the x2 4800+ tonight and see how well that handles.
  2. Well, temps on the Expert have always been very suspect. In the BIOS, at idle i get around 34c. At full cpu usage, i think it hovers around 45-47c. I have my current VID set at 1.55v now, instead of the higher 1.58-1.6 i had been using. Like I said, I'll have a x2 4800+ to play with this Friday, so I hope that it will play a bit more nice than the x2 3800+ regarding the max of 270MHz FSB. (HTT). I appreciate you posting your settings, and look forward to see how much more I can tweak out of this chip.
  3. Please do not hijack threads. Make a thread of your own. However, in response look a few posts above for BIOS tweaks i posted. I am using the EXPERT version though.
  4. LvL 7 and LvL 3 actually decrease the stability of the system by a tad (2720Mhz fails with Prime...it used to be stable, but 2700MHz is fine for now), Combos of 7/1 5/1 3/1 and 5/3 3/3 result in a system reboot during windows startup. I think this CPU has hit its limit with my cooling/RAM/mobo. I'll keep tweaking though. I have a 4800+ X2 coming friday, so I'll see what that does on my system. -Shaun
  5. Well, i have the RAM on a divider of 166. Would that matter much if I got different RAM and left the divider the same?
  6. Well, i've tried numerous other settings. Looks like the HTT(fsb) craps out at 272MHz. I think this CPU could go a higher if it weren't for that limit. Anyone with known tweaks to up the HTT?
  7. Googled and found a guy who had an X2 3800+ on water doing 2900MHz. He said, and i quote : "You could try lower the max async latency and read preable like I did, I thought it didn't matter since my Ram can run stable @ 250Mhz but putting mem divider makes it unstable even when the RAM is running lowever than 240Mhz." Funny thing is, I can't find where i found it...some forum somewhere. Well, whoever posted it, thanks! I saved it to a text file, printed it off, and changed a few settings and now i'm up to 2700MHz vs my old limit of 2400MHz. Not bad for $150! Now, I think my HT is limiting me at 270MHz....anyone have any idea on how to tweak to raise the limit? -Shaun
  8. Ok....here's my tweaks that got it to 2700MHz! I hope this has a bit more left in it though... DRAM Frequency Set - 166 Command Per Clock (CPC) - enable CAS Latency Control (Tcl) - 3 RAS# to CAS# delay (Trcd) - 04 Bus Clocks Min RAS# active time (Tras) - 04 Bus Clocks Row precharge time (Trp) - 04 Bus Clocks Row Cycle time (Trc) - 08 Bus Clocks Row refresh cyc time (Trfc) - 16 Bus Clocks Row to Row delay (Trrd) - 04 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) - 3120 Cycles Write CAS Latency (Twcl) - auto DRAM Bank Interleave - Enabled DQS Skew Control - Auto DQS Skew Value - 0 DRAM Drive Strength - Level 8 DRAM Data Drive Strength - Level 4 Max Async Latency - 10.0 Nano Seconds DRAM Response Time - Normal Read Preamble Time - 8.0 Nano Seconds IdleCycle Limit - 256 Cycles Dynamic Counter - Disabled R/W Queue Bypass - 16x Bypass Max - 04x 32 Byte Granularity - Disable(4 Bursts)
  9. EDIT: I got to 2700MHz, look down a few posts to see what tweaks i did to the BIOS to get there. Ok, I bought into the price reduction hype and am the owner of a brand-new spanking 3800+ x2 CPU. I was excited to get this because I'm usually multitasking quite heavily with Photoshop, Illustrator and a few other programs. However, I "upgraded" from an Opteron 146 running at 2900Mhz to this that won't overclock past 2400Mhz. Help? :confused: I have read the OC guide through and through, with little help getting past 2400Mhz. I also read somewhere a lot of people can't get past 2400Mhz with the 3800 x2's, and this is the place to come for expert help. Notice that I am using WATER COOLING, so heat should be a huge factor. I have tried DOZENS of settings, and can't find a way past 2400Mhz. Here is my system config settings. I also have my sig updated (yes, i read the forum rules!) FSB Bus Frequency - 240 LDT/FSB Frequency Ratio - x3 CPU/FSB Frequency Ratio - x10 PCI eXpress Frequency - 100Mhz CPU VID StartUp Value - Startup CPU VID Control - 1.5v CPU VID Special Control - Above VID * 102.4.% LDT Voltage Control - 1.3v Chip Set Voltage Control - 1.5v DRAM Voltage Control - 2.8v DRAM Configuration Settings: DRAM Frequency Set - 166 Command Per Clock (CPC) - enable CAS Latency Control (Tcl) - 3 RAS# to CAS# delay (Trcd) - 04 Bus Clocks Min RAS# active time (Tras) - 08 Bus Clocks Row precharge time (Trp) - 04 Bus Clocks Row Cycle time (Trc) - 12 Bus Clocks Row refresh cyc time (Trfc) - 16 Bus Clocks Row to Row delay (Trrd) - 04 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) - 3120 Cycles Write CAS Latency (Twcl) - auto DRAM Bank Interleave - Enabled DQS Skew Control - Auto DQS Skew Value - 0 DRAM Drive Strength - Level 8 DRAM Data Drive Strength - Level 4 Max Async Latency - 8.0 Nano Seconds DRAM Response Time - Normal Read Preamble Time - 6.0 Nano Seconds IdleCycle Limit - 256 Cycles Dynamic Counter - Disabled R/W Queue Bypass - 16x Bypass Max - 04x 32 Byte Granularity - Disable(4 Bursts)
  10. He's right, it's the nvidia firewall/ethernet connection. I tried disabling the firewall, active armor, etc...but i'd still received BSOD's of "IRQL not less". My only solution was the same. Disable the nvidia ethernet port, and use the Marvell. Never really had a problem since. I've only had a few "system freezes" for about 20 seconds and that only occured during internet web surfing. Personally, the ethernet ports on this motherboard (SLI-DR Expert) leave a LOT to be desired.
