Overclock 2 pairs of TR3X6G1600C9


Recommended Posts

Can someone help me out, i've been reading this forum and all over the web and think i'm very confused. First time overclocking. Basically I want to run this thing as high as I can, overclocking the processor and tweaking the memory (not even sure if their are any tweaks).

 

Both test I set the board to XMP instead of manual. BCLK was set to default of 133, DDR Freq 1600mhz, QPI to6400.

 

second i set BCLK 190, ddr freq 1523 (other values where above 1600), QPI 6857 (lowest it allowed).

OCCT shuts down on overheat after 30sec into the test. Just want to know that i'm on the right track selecting settings as i start going lower.

I attached the everest benchmarks. Not sure that the 190 settings are producing better results.

 

Suggestions on what I should be tweaking, starting points etc?

Overclocking two sets of modules is touchy. The memory controller (MCH/Northbridge) is already being put to the test since it must load and access double the pathways. So I do not advise an overclock of the memory.

 

However, your issue is that you are overclocking that i7 quite highly and very likely are not dealing with the temperature issues.

 

What cooler are you using?

 

Download Real Temp from-->

For i7

Download LinX - Linpack that will run on Core i7 8 threads fullbore. Do NOT use this program if you are running with stock cooling.

 

Download LinX from-->

Run Linpack for full memory (1) and use a 5 pass iteration. Run Real Temp and watch the temperatures. Let the Linpack program run for the full 5 passes. The output in the screen Residual <norm> will give you five sets of values. They should be identical for a stable CPU and DRAM.

 

Be sure to turn off your screensavers, display settings that turn the monitor off for this test.

 

What are your temperatures with LinX?

I'm using a Cool Master V8 for the CPU.

 

I bumped the CPU down to 160 (3.2ghz). I ran Everest, Real Temp and LinX. Below's the LinX results, attached the other 2.

Seems like its ok but the temp goes up to around 81, is that too much? Can I start pushing it say in increments of 5 until LinX shows different results?

You can drop a good 10C when comparing LinX with Prime95. My overclock reaches 90C but idles at 35/37/35/37 and I have never seen it do more than 65 - 70C at full gaming, compressing, and video rendering. I would not worry with 81C LinX personally. You can increase with increments of 5 and testing for stability. Also, keep in mind, that you can also drop a good 10C with disable of the Hyperthread. Most people do this because there are very few programs that make use of such threading. I run with 3.6Ghz and the HT and Turbo enabled personally though.

i920 on H2O//TRUE//Stock coolers under OC conditions.

 

It is the prevailing view that the max temp for an i7920 is 90C (after which BSOD). At 3.8 TRUE is doing 83C at 100% load in open case, I think you have to add 4-5C to that in closed case. This means temperature could be the limiting factor in a i7 overclock. At least for air coolers. From the looks of it, 4Ghz will be a max for most air OC of this line of cpus. Still pretty impressive. of course those with water blocks can push the chip more.

Cool. think i found my sweet spot setting. 175 (3.5ghz). Goes up to 88 degrees at full load, still get consistent results with LinX. Occt runs for almost an hour before complaining that the 88 deg is too hot.

 

Thanks for the help!

Looks good to me :)
