are there any better options that don't involve voiding the warranty?

The only way I see you getting cooler temps is a 3rd party heatsink or having liquid cooling. The latter being much more expensive :C

That's not to say, if you are running at 250 HTT that somehow you'll get more out of your CPU, but multi might only give you 4.3ghz, and the chip might flake out at 4.360.
The system does seem a tad bit snazzier when I have it set to a high HTT; placebo or not, I'm not 100% sure. The benchmarks seem to indicate it as well, but the difference is so minute that it's not worth the additional headaches.
My system is weird too, because if I drop the ram multi to 4x (800) and jack the FSB to say 250, it doesn't work nearly as well. It's also rated to run 2.3V @ 1066 @ 5-5-5-15-2. I'm not sure where they got their "ratings" from but I run it @ 1066 @ 5-5-5-15-2 @ 1.9V, lol. Anything higher than that and it gets funny, which I think is a problem with ddr2 imc to begin with.

I wish it were that simple. I test every component...but every time I change something, 'stable' maxes change. For instance, I can run say 4GHz at 1.45v and 200MHz x 20. But lets say I go to 250 core clock so I can OC my RAM and change the multiplier to match to 4GHz, now it's not stable at all, even at 1.5v. Or I change nothing but the NB to 3000MHz and it's fine. I change the CPU up and NB is no longer stable. I wish it were as easy as finding the max of each component individually and throwing them all together...but they all seem to effect each other in a multitude of ways. So far I know I can run 3GHz NB stable by itself, but once I start changing other things, that changes. And with RAM, too, some frequencies are stable with some settings and not with others, and not necissarily what you'd think, i.e. higher or lower. Weird combinations...

On a side note I had a nightmare tonight when testing for max RAM clocks by changing the core clock. I started at 260 core/2080Mhz and worked my way all the way down to 220/1760. At this point, as to be expected, I had some really weird stuff going on when the system would hiccup from unstable RAM speeds, like it would POST and boot but restart once it got to the welcome screen, etc. One of the weird things: Windows 7 gives the option to do a 'startup repair' if it detects the system didn't boot properly, and it goes into a recovery console. Sometimes, when I choose to "Start Windows Normally", it shows the boot animation for recovery console but boots into Win 7 normally.
Well, eventually it just restarted at welcome screen every single time..no matter what my settings were. Safe Mode worked, but nothing else. CMOS clear, etc etc, you name it. System would not boot from testing RAM speeds...nightmare. Thought I needed new RAM or corrupted the OS somehow. Eventually I got back into Windows by using F8 and choosing "Last know good configuration", but I got an 'unknown device could not be installed' error, and could not connect to the internet.
After some investigation, I found that critical Windows services were not starting and I could not start them manually, nor could Windows (access denied). I ended up in the registry and all that ****...HKLM/CurrentControlSet/Services and changed permissions to allow all for all everything...cuz I was desperate. I finally figured out what happened: Windows booted using it's "Selective Startup" rules from either the Recovery Console or Safe Mode in the NORMAL operating system environment, and rewrote access privileges and service startup rules for everything in the OS onto the normal boot routine when it started up one of those times. Ended up in msconfig and all I had to do was uncheck "Selective Startup" and recheck normal startup. I want my 3 hours back frown.gif

tl;dr of the above: crashing your computer over and over again testing components can eff you over big time. Felt very tech savvy figuring out this problem but wasn't worth the time spent tongue.gif

Also, for those of you that have made it this far, I have a question: it's about vBoost (I think I've heard it called vDrop as opposed to vDroop). I did 4GHz @ 200 x 20, and I ended up putting my vCore all the way up to about 1.45 and it still wasn't stable (*** mate.). But when I would run prime95, or any load, my vCore would slowly rise from ~1.46v at idle to 1.48+. I saw it go from 1.43 (1.425 in bios) to 1.48v. Why is my system adding .05v+ to my bios selection? that seems insane. I've disabled all the obvious power "features" that I know of, CnQ, Turbo, C1E, LLC. Should I turn them back on...? This kind of jump is common across almost all my vCore voltages, except some sweet spots like 1.275 which varies a lot less, etc.

Hmmm, well, for your windows problem, that sucks. Back in the old XP days it was worse. You'd overclock and in an instant you'd get the some corrupted files. Bam, 2-3 hours down the drain to fix the os. 7 is far more stable and you really have to work hard to bork it up.

I'd start thinking your motherboard might be contributing to part of your problem. People say that the refclk is just a number, but the system behaves funny with it set too high, even if everything else is well within spec.

In the end, best to use the cpu multi, minor htt bumps and leave the htlink as close to stock as possible (I tested it up to 3.0ghz and couldn't see any reason to have it that high), and o/c the hell out of the northbridge.

To get my ddr2 working @ 1066 requires a 267mhz fsb, which my motherboard doesn't like -- so right there, I'd lose out on my ram. The only benefit I can see from running it like that is I get to choose from lower latencies. Choosing 5.33x I no longer have access to certain timings.

BadRobot:

oh! sorry but i have some ask for u:

how many ºC is the normal temp in prime95?

in 4 cores?
in 6 cores?


if im the 1600T over 62º its safety no?

and in game the micro is arround 45º/49º (battlefield 3)

what do u think about this?

please i whant to know if my computer its fine or is worst.....

Its best to keep the temperature under 60*C. That's what the others told me smile.gif 45*C is a great temperature! My cooler is quite good so during stress test with prime95 my maximum temp is 46*C

@Ozzy I finally got to 4Ghz wiht 200x20 @1.5 stable enough for 5 minutes. Though of course the error I get is the rounding one from Prime95. That'll be solved with RAM timings (seemed to work last time by setting them looser instead of tighter).
edit:: I upped the voltage to 1.51 and it lasted longer in Prime95. It's now at 1.52V with my RAM timings on 11-11-11-28-2T. Loosening the RAM has worked before on my OC to 3.8Ghz. Right now It has lasted over 10 minutes which is promising.

I'm also having the same thing as Kylezo that CPU-Z and CPUID don't actually have the correct voltage but rather a variation of +-0.05. It's probably how it's measured I guess.
When I first start it up CPU-Z registers 1.5V (when its at 1.52 in the BIOS) and while Prime95 runs the voltage goes down to 1.464V??? It's going lower than I guessed it would.

Yeah, reference clock is one of the 'system components' i checked to see how high I could get it. I think I went up to like 300MHz keeping evrything else the same as before and I stopped cuz I'd never use it that high. But once again, once I start changing stuff, the rules go out the window...

Well you've got vDroop which is at least a lot more well documented than the significant (and sometimes scary) boost that I'm seeing in my system. Got any power management features on? Also some people don't trust CPU-Z for vCore readings, so try a couple different applications and see if you like one better than the other. More than likely, though, it's just your motherboard and/or PSU causing the vDroop.

None at all. Everything is disabled like you have it (LLC, CnQ, CE1 support). I guess vDroop is good lol. I still find it weird so I'll have to read up on it.

Found in an articale on it:
Quote:
If you’re looking for vdroop on your own system, you’ll only see it if all of the power saving features (such as SpeedStep, C1E, and C-States) are disabled. Vdroop is still there even if the power saving features are enabled, but you just won’t be able to notice it as easily.

Sweet sweet overclock =D I'm leaving my pc prime test overnight while taking screenshots every minute just in case it crashes and it loses the results ^^
-Good night 960/1600/1605-T Club

edit: bah...it did 1 hour and hasn't failed yet, temp max is at 47*C, voltage still drooped to 1.464V (1.52 in BIOS)...so I'm calling this one stable. Tomorrow's schedule? Benchmarks =D

to the guys running a 1600T/1605T.
what are you using to monitor your "core temps"?
hw monitor, core temp and everest dont show jack.
i have always watched the CPU temp, but i guess i should have been watching the core temps instead.
i guess the cpu temp could read 7c-10c higher than what it actually is-is this true?

just picked one up off newegg for $125, hoping to get lucky with an x6 unlock. I'll either be using this or my x6 1405T with an ASUS M599X Evo as a server. I'll post back results when I get the chip
