wevsspot Posted May 17, 2008 Posted May 17, 2008 Sabmac, I'm going to help you out by giving you a starting point in your overclocking adventure. Try these settings. You may need to change the strap because A is the tightest (266) but it also yields the closest RAM speed to that specified by the mfg. MB Intelligent Tweaker (M.I.T.) Robust Graphics Booster............. - Auto CPU Clock Ratio..................... - 9 CPU Host Clock Control.............. - Enable CPU Host Frequency (Mhz)............ - 423 PCIe Frequency (Mhz)................ - Auto Performance Mode.................... - Turbo C.I.A.2............................. - Disabled System Memory Multiplier (SPD)...... - 2.50A Memory Frequency (Mhz).............. - 1058 DRAM Timing Selectable (SPD)........ - Manual CAS Latency Time.................... - 5 DRAM RAS# to CAS# Delay............. - 7 DRAM RAS# Precharge................. - 7 Precharge Delay (tRAS).............. - 25 ACT to ACT Delay (tRRD)............. - Auto Bank Write to READ Delay............ - Auto Write to Precharch Delay............ - Auto Refresh to ACT Delay................ - 52 - 56 experiment (lower is better) Read to Precharge Delay............. - Auto Static tRead Value.................. - 8 - 10 experiment (lower is better) Static tRead Phase Adjustment....... - Auto Clock & Skew Controls............... - all at defaults System Voltage Control.............. - Manual DDR2 OverVoltage Control............ - .10 PCI-E OverVoltage Control........... - Normal FSB OverVoltage Control............. - Normal (G)MCH OverVoltage Control.......... - Normal MCH Reference Voltage Control....... - Normal DDR Reference Voltage Control....... - Normal DDR Termination Voltage Control..... - Normal GTL Ref1 Voltage Ratio.............. - Normal GTL Ref2 Voltage Ratio.............. - Normal Loadline Calibration................ - Disable CPU Voltage Control................. - 1.2875 Normal CPU Vcore.................... - 1.225V Share this post Link to post Share on other sites More sharing options...
Sabmac Posted May 17, 2008 Posted May 17, 2008 Thanks so much for that wevsspot, that's a lot of effort... apparently in vain. Passes the stat test, then reboots itself after memory test and keeps all settings except CPU host frequency (or FSB). Is my memory faulty?

wevsspot Posted May 17, 2008 Posted May 17, 2008 Not necessarily. For now change the strap to 2.0b and that should get you a successful boot. I'm fixing to go to dinner, so hurry Share this post Link to post Share on other sites More sharing options...
Sabmac Posted May 18, 2008 Posted May 18, 2008 Works! You're a legend! Sorry for late reply, watched some footy. One area of concern, my CPU and GPU are both not showing up in CPUID now. Would you be able to explain what you've done with these settings? I can't have an overclock without knowing how it was achieved, that would be cheating... You don't have to delay dinner due to me, lol. Perhaps you're as excited as I am. Share this post Link to post Share on other sites More sharing options...
wevsspot Posted May 18, 2008 Posted May 18, 2008 what version of cpuz are you running? mine works fine with version 1.43 we aren't totally out of the woods yet, since using the 2.00b divider and strap is running your memory very underclocked. another way to go about this is to reduce your cpu multiplier and up your fsb. try this; change cpu multiplier to 8 leave memory on 2.00b divider and strap change your fsb to 475 this will also yield a cpu clock of 3.8ghz and your RAM should now be running at 950mhz you may have to bump up a couple of your voltages by one or two notches. here would be my recommended starting points - start here and reduce one increment at a time until system becomes unstable. PCI-E Overvoltage Control - .20 FSB Overvoltage Control - .20 (G) MCH Overvoltage Control - .150 Share this post Link to post Share on other sites More sharing options...
Sabmac Posted May 18, 2008 Posted May 18, 2008 CPU-Z is working fine, CPUID (temperature monitoring) isn't. This is a lot of work mate, I appreciate you going through this with me but it's bed time now. Pick this up tomorrow? I know it's a drag but it's all work, sleep and the girlfriend is coming over to bother me tonight (bed time is around midday, graveyard shift.)

wevsspot Posted May 18, 2008 Posted May 18, 2008 NP, Have a good night's rest. Talk to you tomorrow. Share this post Link to post Share on other sites More sharing options...
Sabmac Posted May 18, 2008 Posted May 18, 2008 Morning! I used your new FSB and multiplier, got the voltages to .10 .10 and .100, which I think is an okay amount. I might lower them in future. prime95'd it for a couple of minutes, don't dare doing it for longer until my heatsink is installed. Temps seemed fine (with a low ambient temp) and no errors recorded.

Sabmac, Please please please tell me that you have some sort of heatsink sitting on top of your processor, even if it's only the factory one.

LOL yes of course, factory heatsink. I've ordered a Tuniq Tower (it was on special) so I don't want to stress the orig heatsink too badly until I have that one installed.

You know me, the only dumb question is the one that never gets asked. The Tuniq Tower is a very nice air cooling solution. The overclocks I've started you with are pretty mild. There is probably quite a bit more left in both your processor and memory if you want to push it that far. Smart to wait on the good cooler though. Good luck and keep me posted.
