Windows 7: What's your memory assessment speed?

your ram is running at 1066, 533x2 (double data rate)=1066



dont look at the SPD tab in CPU-Z it is a graph table NOT YOUR REAL TIMINGS.
the only tab you look at is the MEMORY tab.

In your BIOS, adjust your tRFC setting to 40, and try to set you CR
(command rate) to 1T, if it boots into Windows normal then it should be faster.

other than that, try to overclock your FSB or CPU speed.

post screen shots if you adjust them.

Everything I have read has said that 52 should be the lowest for me, are you sure 40? Seems like it would cause instability to me.

My bios doesn't give the option to bring ram up to 533. 400 is the highest it shows.

CPUZ is showing my RAM as PC2-6400 (400MHz), Shouldn't it be listed as PC2-8500(533MHz)?

Update: I changed my FSB to 333 with 9 multiplier and matched my ram with it, Also when I change my CAS latencys down to 4 4 4 15 I get boot failure o.O

And yet another update from me, I'm going to break something ;-P, at 333 FSB when I used OCCT to stress test it stoped within 3 mins after getting over 70c, Just tested at 80c. Will this hurt my CPU? My fans are running, all 3 of them, and my voltage is well under the limit but my system is getting hot. Stock fan but not stock Themal Grease. Should I reapply the Grease?

Where is CPU-Z showing your RAM as 400MHz? The screenshot you posted has your RAM being listed correctly.

As for the temps, try re-applying the thermal grease, but properly clean off the other stuff as putting too much can increase temps. You only need a grain of rice sized amount on the CPU, although the stock cooler will also be causing a problem as it isn't exactly the most suitable cooler for benchmarking, though make sure it's properly fitted as well.

ok, you no longer need to worry about your memory as its at 533(1066).
also your default multiplier is 10.5 so i would be running it at 10.5 to get full advantage of it.

try 320 FSB with the 10.5 multiplier. that should give you 3.36ghz.
BUT leave your ram at 5/5/5/15, i think the reason for boot fail is because you changed it to 4/4/4. the reason for that is because the actual chips used on the memory has a latency value of 5, by lowering it to 4 and keeping the memory speed,not increasing voltage slightly and not increasing other memory timing values, it will try to do the impossible, which is...impossible for the chip.

as for CPU-Z showing 400mhz, it also tells me mine is 1333mhz, which it is in fact 1600, its strange how it works.

i think the 40 value setting is a realistic value, its not insanely low. mine is set to 2, so a small decrease to 40 should be well over achievable.

and your temps do seem high. even for a stock intel cooler. when you applied the paste, was the cooler clean and it had a flat contact surface? (some intel coolers have thermal grease/pads already applied, so they are a 'plug and play' setup, so you need to make sure you remove the original stuff first).
all you need is a perfectly thin layer. i have always had good results from a thin layer on both the cpu and cooler surface, and by thin i mean THIN, its only purpose is to fill in the microscopic gaps and impure flat surface between the two layers, by putting too much can cause overheating, as its restricting the heat dissipation.
all Intel cpu's have a thermal shutdown zone. once they hit their max (TjMax-thermal junction, between the 2 cores) it will force an immediate shutdown, no BSOD nothing, no delay no warning, that way there is little or no chance to damage the internals of the cpu. it will then have to wait until it cools below the max setting before it will function again. its handy having that feature

so...i would re-past that cpu, try out the settings i mentioned above @ 320 FSB and leave the mem timings at 5/5/5/15. see if it works.

this is the specs on your CPU.
Intel® Core?2 Duo Desktop Processor E7400 - SLB9Y

anyway, here are the timings i run on my memory.



let me know what happens, i gota get some rest.

Well said. I remember AMD users burning the CPU out easily. With improper heatsink applied or improper cpu paste technique, trouble immediately!

i think there was confusion with CPU-Z on the SPD tab page. i dont know how many times i have seen people get confused with that stupid graph/table example area. it states my ram is also 667(1333)mhz but is actually 800(1600)mhz. and i dont think my ram will even run at 1.5v. its range is between 1.7-1.85 from the OEM website yet JEDEK XMP profile states 1.5 @ 1600mhz? some XMP that is.

geez i remember those days, i think that is what originally turned me off AMD, even though it was quite a few years ago, it still floats in the back of my mind, although they would have more than likely fixed that issue within a few new cpu designs from that date, as there would have been alot of unhappy enthusiasts

When I change the FSB to 320, should I change the (G)MCH Frequency Latch from 266 with 4.00a Multiplier? I'm guessing not but I'm not too sure about this.

And I think when I took my comp apart 2 days ago to clean the dust out, when I removed the heat sync it broke the thermal paste bond or something. After reapplying the temps are back down to normal.

CPU-Z was showing that under the SPD tab, but I guess that is just the chip standard settings?

Thanks to all of you for the advice. Here are the new screenshots.

ahh excellent, hows the system running at 320 FSB? is it overheating still, did you re-paste the cpu at all?

i noticed your ram has dropped back down from 533mhz?

is there a noticeable speed gain now at 320? personally i would invest in a new cpu cooler, and i would set the 320FSB as the max limit for the stockie. once you get a better cooler you can go higher

did you happen to try the 5/5/5/15/2T/40 timings? also another hint, if you want the ram to run faster, try setting that CR command rate down to 1T. that will give it a hefty boost, and seeing as your ram is rated at 1066mhz and its running at 960mhz you may just get 1T to work strait off the bat, as usually you would have to loosen timings (increase them), increase voltage a tad and sometimes decrease the mhz on the ram. but sometimes 1T can be worth it all. it usually boosts it by anywhere from 1000mb/s to 3000mb/s! there is no harm in trying!

all that matters in overclocking is that your careful with increasing voltages, the cpu is usually ok as it has thermal protection, but some motherboards do not have overheat/overvolt protect and i HAVE killed a old ddr2 mobo i had years ago by increasing the northbridge voltage a bit too high (i was still learning to overclock lga775 boards). and also the ram can be a bit sensitive to voltage, but stay around the 1.8-2.0v and you should be fine with that.

there are probably heaps of people here that can help in overclocking, but this forum is more dedicated to operating systems, so if you want to learn more, there is a forum i joined some time ago, and have learnt heaps from them in the past!
