    TO be honest it's really not worth going through too much pain to get the 400 strrap going. put the strap setting on auto and try all the settings for system memory multipliar that get your RAM at or near the speed you want to run it at.

    Start with a FSB of 333 and a multiplier of 10.5 to get 3.5GHz. Use the 2.4B multiplier to get DDR-800. If it's stable, up the FSB a little to 345. A 1:1 ratio is no different from using a higher multiplier. You won't get better performance from a 1:1 ratio, not on an Intel Core 2 platform.

    You seem to be using "Strap" and "FSB" interchangably. They're totally different. If your motherboard has a 400 strap, then of course it's able to use it. It's the RAM and CPU that dictate it's stability, along with timings and voltages set.

    E5200's that can run a 400 FSB are in the minority. Your CPU has a 12.5 multiplier.... use it, or at least use *10 or more. There's no need to try and go for a 400FSB. The only difference you'll likely see is in benchmarks. CPU speed is king.

    Psycho, I have good news. I traded my friend my OCZ Fatal1ty RAM for his OCZ Gold that does 1066 Mhz @ 5-6-6-18 2.1V (I know, not the best timings, but better...) My big question now is - Do certain straps only allow your FSB multi to get so high?

    ex. Can a 200Mhz strap allow you to do 333 x 10 ?

    I understand that certain straps will allow different latencies for your RAM...

    I also heard that if you are wanting to do the 400 Mhz Strap you should set your FSB multi below or above 400 by a tad bit. Maybe I should give that a shot?

    Straps seem for me to either work or not. they don't do anything more, or at least I haven't gotten them to.

    At the moment with the over clock in my sig, I can run with a multiplier of either 2.5A or 2.66C. most others that keep my RAM in a sensible range (leaving only both 1:1 multi's and 2.66D) fail to boot completely, no matter the settings.

    From my testing I've concluded that on my combination of components (same was true on my Q8200, just different multi's were awkward) that strap selection is often hit and miss, and it's better to try all within your RAMs operating range for the best stability. This doesn't over ride my fundamental principle of setting an over clock I want then working on getting stable. It just means I'll try straps and multipliers first on something I believe should otherwise work.

    I was able to do 333 x 10.5 = 3500 Mhz, but it required much more vcore than my 1.24375 at 3333 Mhz. I would really like to do 3500+ Mhz, but my main problem is my load temperatures.

    I am using an Arctic Cooling Freezer 7 Pro with Arctic Silver 5. Real Temp reports 65-68 C during Intel Burn Test [max 10 loops] @ 3500 Mhz. When I have it at 333 x 10 @ 1.24375v, I get around 60-62 C Max load temp via Real Temp.

    Are these temperatures bad enough to lower my OC & vcore? For some strange reason my BIOS reports a lower CPU temperature than does Real Temp. I am more inclined to trust Real Temp, but I'm not for sure. I think I need to re apply AS5 on my heatsink in vertical lines under the heatpipes. I used the spreading technique and I've been told this is not as efficient as spreading thin lines. Is this true?

    Also, why does Windows recognize the speed of my CPU wrong? CPU-Z recognizes the speed right, but most games / other apps recognize my CPU speed incorrect.

    If anyone can answer any of my questions above I would greatly appreciate it.

    Re-applying your thermal paste will likely not reduce temps by much. If you used the right amount first time that is.

    65-68c is acceptable at least to me, when running IBT. My overclock reaches ~71c using IBT, but only gets as high as 60c under prime load. I've run Realtemp on several occasions all day, while doing various stuff, including gaming and video transcoding. Temps never got over 63c, and averaged I's guess about 60c.

    Your 3500Mhz overclock is more than viable IMO.

    As for Temp readings, the BIOS uses a completely different temp sensor than Tealtemp. Realtemp accesses the CPU's built in temp diodes, imbedded into the cores themselves. The BIOS is reading a temp sensor located on the CPU socket. BIOS readings are often cooler than core readings. It's the core readings that are important, and it's these that Intel refers to when stating the max temperature range. They're not always accurate, as they're designed purely to initiate thermal throttling at the stated TJMax, and are more accurate at high temperatures than low ones. Your sensors sound as if they're in good working order though. Both of mine are stuck at low temps, but start working and matching each other at 40c and above.

    RealTemp & BIOS report temrature that is read from different sensors.

    You will find some info that will clear things up here & here.

    Is it OK that Windows and other games / programs don't recognize the right CPU speed? I notice that when I check the console after Crysis loads it reports my system as 4.16 Ghz instead of the 333 x 10 = 3330 Mhz. It won't hurt performance will it?

    Thank you so much for the suggestions Psycho.

    It is an issue with some programs that don't use the correct way of detecting CPU speed. Crysis is one of those programs, and even windows itself is guilty of it. These progs use the default max multi x current FSB to arrive at the CPU speed, even if you've lowered the multiplier. For example Windows & and even Orthos Prime report my CPU speed as 4.315GHz, (10.5*411) when it is in fact 3.9GHz (9.5*411). Nothing to worry about. What ever CPU-Z reports is highly accurate.
