I paid cheap for the ram and the voltage is the less to concern as it is less than 5V of difference.

You can get a 920 4.2 stable on Air with hyper-threading on with cheap ram at 1.38-1.40 volts?! That has got to be a record.

what settings are you using?

Screen shots?

Has anyone been able to hit 4.0 to 4.1-ish with HT on with a 920 air cooled?

I tried with HT off for giggles... needless to say. with MORE voltage, temps were over 10c lower at load with it off o.0.

The ram and CPU are tied up by the internal memory controller which means if the ram gets corrupted by a minor margin of fluctuations then the CPU will freeze instantly.

My better ram do you mean tighter timings? Or is it ram speed you are referring to?

A little birdy left a gift for me....


Unfortunately, I can't do jack with it until D-Tek releases a LGA 1366 mounting kit for the Fuzion V2

Nice birdie!
have fun...even with the stock cooling!

I didn't even think about that! I can still use the stock cooler, I will get right on it! I was planning on letting it sit in the box till I got the mounting kit, lol...

just leave the screws on the mobo for the water cooler mount loose and tightening the cpu block once in place will work.

for socket 775 to ghetto rig i7 socker

by the way congrats and sick setup!

I will do it later right now I'm at 4.2 1.35V hyper-Threading off watching an important movie

Reserved:

Well I tried but it was not possible due to the high temperatures

That is the reason I keep it 4.2Ghz with 1.35V Hyper-Threading off.

First: Intel recommends it below 1.35
Second: Load times are 10 to 20c degrees less.

The first screenshot is at 4.2Ghz with 1.37,5 which finished 2 tests as Super PI 1M and 32M.



The second screenshot is the reason why I can't go ahead with this. I do respect 10%. An example is if the chips runs with a TJMax of 100c then the maximum I would let is 90c. This is far higher than my 10%, check the Realtemp program well. You will see it reached 100c and it was on the 3rd Prime 95 test 1024k which is a bit further than the beginning of the test.



The conclusion is simple and can see by anybody interested on the topic. If you need to use 8 threads with this speed at 4.2 using the best of the best aircolling solutions the Thermalright true copper 2 kilos then It would be better for you to go water cooling solutions as you will get a better voltage than me with 1.38V 8 threads hyper-threading on.

As for me I will stay with my 4.2Ghz at 1.35V 24/7 4 threads no problems. The reason is again very simple, it is cooler with 4 threads, less voltage, programs which I most use can not even use 4 threads let alone 8 threads.

I hope this helps,

I wouldn't run it that hot; it seems you topped 100C already. A good general rule of thumb for a maximum 24x7 temperature is Tjmax - 20 (Tcontrol).
