The temps are higher than I want for OCCT Linpack, 71C worst instance, Primes95 'Torture' segment shows about 65C highest peaks.

I will try to bring the voltage down a bit more, but from what I read here, over its many posts, I'm about in the same range as most.

It will take some time to figure out all of the V settings, I don't yet know what most of them will accomplish or undo. VCore is now at 1.375V RAM 1.55V.

My 06 3DMark was 15262, I suppose it would be considerably less with a high-res monitor, but no idea how much.

****************
RATS! Blue screen memory dumping lousy crash! Maybe the voltage needs to be a little higher like 1.4'ish'V.
Don't know, but will try some more tonight. Sigh...

Its normal for OCCT to stress your system much more the prime95

indeed, the comfort zone of most E5300s on this thread is around 3.6Ghz...after that, the voltage demand spikes much higher for every +100Mhz overlclock

The safe voltage for the E5300 (or any wolfdale CPU for that matter) is 0.8500v-1.3625v you can still go beyond 1.36v up to 1.45v but anything over 1.36v will degrade your CPU's life span (though if you keep things cool it will happen at a slower rate, but the damage will happen nonetheless)

I am back to 10.5 x 343 (3.6Ghz) since its within the safe limit while my previous max overclock of 3.77Ghz (11 x 343) needs around 1.39v ideal and 1.36v and its only stable enough to play games..forget about stress testing with the stupid stock cooler

So that's why the 3830MHz failed!

And I thought my 1.25 was low! That is why I didn't want to go into the one-point-fours; other than briefly to experiment. Temps too high, and this goes with your advice on the 1.36 safety limit, which I had never had put to me so clearly and explicitly. I now know that voltage and/or high temps can independently hurt these little over-achiever processors.

I am now several hours into a new stress test, 327 x 11.5 = 3760MHz, with a VCore of 1.35V; 1089Mhz DRAM, just barely over rated speed and I let it have 1.55V because it seemed like a good idea!!!

Should that work, I'll crank up the FSB, drop the multiplier back and try to run the same CPU clock. No reason to fail unless my board is approaching that "wall". Will be an interesting comparison.

I'm doing my surfing, e-mail, and forum things with Primes95 working away. It gets a bit distorted in time, but I figure the extra tasking mess will tell its own tale, too.

BTW, where did everyone go? Is this too boring, or are they not involved enough in their own projects to want to share?

If you are more than 2 hours into prime95 then its safe to say that your 3.76Ghz overclock is stable, maybe you should try 3.8Ghz just to round things up

Also, you DRAM voltage is fine so don't worry about it

The E5300 is a relatively old CPU now so its good enough that this thread reached 1000+ posts

Yes, old, and about $66.00 several months back when I bought some for cheap customer builds, expecting NONE of this potential!

Look at the price of my rig so cleverly hidden in the "My System" link.

What now? I've got my eye on an i7 875, just as soon as everyone thinks a processor must have an "i7-9--" in front, they will be just right. Maybe sixty days?

Maybe these old E5300s are no longer available and this thread will wind down.

I'll see you at the next hot topic that has some common ground. Thanks for all the encouragement and tech-support. Happy trails...

that upgrade is nice but unnecessary until quad core games are the norm..so far only like 2-3% of games are quad core optimized so it isn't a mandatory upgrade if you want to game until maybe a year or so

Hey watching this thread, wonderfull work guys.

You mention here, about the quad core games, which I have had a recent delema with, but seem to have overcome at 3.6 mhz, at least to the degree that I am now competetive.

I do have moments where those nano seconds cost me a kill.

FYI Agency, Im at 333 FSB @ 1.275v (bios). RAM at 889. 3D-05 doing 20k . Core temps 58c max P95. Res is 1024x768, on those 3D tests.

Also if if push up even a little I too have to add lots of voltage.

Iconan,

I like that 3.66G, a clean, totally stable, even running OCCT Linpack, and low voltage O.C. My temps don't touch 65C there and upper 50sC most of the other tests.

That works slightly better than my old standby of 3497MHz, 269X13, I think I'll try it for a while before I go back up. The faster FSB should have some dividends too, as you have found.

I am pretty sure my 3760MHz config. will work in the long run, but with work to do, I have to put that off.

BTW, JEDEC standards for my memory shows 7,7,7,20,27 at 1066, but it will not boot even at your 3660MHz! Auto DRAM sets me at 7,9,9,25,75.
