Guys I recently traded my Q6600 to my girlfriend's Q9550. Boy I'm lucky without any payment. I do more stuff on the PC than she does so 2.4Ghz wont hurt her. And I needed something stocked at a almost 3Ghz so I won't have problems overclocking it. Plus! Its a E0 revision so I overclocked it to 3.2Ghz at [Auto] core voltage. Since I didn't know what voltage it would need. I haven't stress tested it yet any app suggestion? I know there are a lot out there but I want a specific trusted stress test app to be precise. Just look at my signature rig for more information.

Thanks!

4554MHz stable. That's awesome!

I need a Quad.

Hey guys, hope someone can help me,

I overclocked my system around two years ago to 3.83GHz in 'Sync' mode through the bios and produced 900MHz memory. I used standard timings and memory voltage and only changed two voltage settings. These were northbridge, which I set to 1.40V - and also vCore which I set to 1.22500. I was able to boot into Windows etc, and pass quick stability tests. This previous overclock was with a Noctua NH-D14 in push-pull configuration so I was not able to pump enough volts in to fully stabilise the system. Temps were around 68*C with Intel Burn Test.

However, I recently purchased a new Antec cooler, a closed loop water cooler. It idles around 35*C @ stock, and never above 50*C @ stock full load. I love it!!!

This has brought with itself a big problem. Now that I have the cooling headroom to get 100% stable I cannot seem to find the correct mix of settings in bios. I will post my bios settings below.

FSB and Memory Config
FSB Memory Clock Mode === Linked
FSB Memory Ratio === Sync Mode
FSB (QDR) MHz === 1800

1.2V HT Voltage === 1.30
Bridge Core Voltage === AUTO

CPU GTL_REF Voltage === +30mV
NB GTL_REF Voltage === +20mV
Currently idling @ 45*C, vCore must be way too high - IDK. crashes different cores on Prime95, and crashes Hyper-Pi on anything larger than 4M places of p. Also crashes GTAIV, (Which I have found to be the best game for stressing systems across the board. I max every setting out and force V-Sync off, never falls below 35FPS, 60-80s usually, well as long as it doesn't rain then its like 20-25FPS. tongue.gif)

Well, I just don't know what to do, been steadily rising vCore with little to no improvement. I even went all out last night and reset the FSB to 1568 to produce 3.33GHz and couldn't even get that stable. I must be missing something or not testing properly. Its like some people say Loadline Calibration is bad, then others say use it. I actually seem to get more stability with it Disabled.

My PC is Prime stable 24/7 @ stock. Intel Burn Test all week!

PLS help me guys, I know at least one of you will have my exact setup running at 4GHz, I just want 1800MHz FSB 1:1 ratio! I will erase my memory timings if needed. Normal for my RAM is 5-5-5-15-2T @ 2.1V, but the sticks can take 2.2V all day long!


That's it I've finished - PLS help.

Perhaps your hitting a FSB wall, the Nvidia chipsets arent the best when it comes to high overclocks on quads. A good way to test this out is to reduce your CPU multi to the lowest setting, and loosen ram timings so you can remove the CPU and Memory from the equation. Run blend for 12 hours and see if you have any errors, bsod's, or freezing. If in fact you have no issue, then move on to the memory.

Generally speaking, when you try to push the last few hundred mhz out of a chip, you have to do alot more work to get it stable, compared to the first 600-800mhz tongue.gif.

Thanks for quick reply, lose the RAM and reduce multiplier but keep same voltages?

Yeah, you can keep the same voltages.

At 6.0x now, ram is at 5-6-6-21-2T set by bios @ AUTO. Really hate to lose my RAM timings though because my latency was great at 4-4-4-12: 48.0ns. Now its a pathetic 56.1ns. Do you recommend that I use the RAM at the normal SPD of 5-5-5-15 @ 2T? Which gives around 52ns

Also, I have set all CPU and MB voltages to AUTO and read them through Everest to get their initial values and go from there. vCore @ AUTO setting is at 1.3280V idling @ 40*C. Running Intel Burn Test now.
